Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components or the two components and any additional member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature

Description
- The present application claims the benefit of priority under 35 U.S.C. § 120 as a continuation of U.S. patent application Ser. No. 10/952,540 titled “Self-Contained Axle Module” and having a filing date of Sep. 28, 2004, the complete disclosure of which is hereby incorporated by reference.
- The present invention relates generally to hybrid electric vehicles, and more particularly to a self-contained axle module for an electric vehicle.
- In a conventional electric vehicle, a prime mover such as a diesel engine, is used to drive an electric generator or alternator which supplies electric current to a plurality of electric motors. The electric motors typically are coupled to wheel sets, in line, on the vehicle. The vehicles that utilize this type of hybrid electric motor are typically railroad locomotives.
- The prime mover drives the generator/alternator that typically produces an AC current that is then fully rectified with resulting DC current and voltage being distributed to current converters coupled to the electric motors. Such systems are highly integrated with each of the components typically designed and manufactured to operate with the other components in the overall system. In other words, “off the shelf” components are not readily adaptable for use in the initial design or ongoing maintenance of such vehicles. Further, such vehicles have multiple components associated with the change of AC to DC to AC power. Maintenance of such systems is expensive since specific components must be used.
- In the use of hybrid drives for such electric vehicles, it is often necessary to add support systems such as pressurized lubrication and supplemental cooling for the motors and other components. Typically, these systems are centrally mounted on the vehicle and require the routing of specialized, pressurized, conduits to move the oil and coolant medium to specific points around the vehicle. Such additional equipment in conduit routings typically take up space that could be utilized for other purposes, such as cargo space. Such arrangements also are not cost effective since additional materials, i.e., conduits, pumps, filters, are required.
- Thus there is a need for a self contained axle module for an electric vehicle that includes lubrication pump, filter, heat exchanger integrated into a single module. There is a further need for a self-contained axle module for a hybrid electric vehicle that is easy to replace and repair, particularly in the field. There is also a need for an electric vehicle that includes a self-contained axle module.
- There is provided a self-contained axle module for a vehicle. The vehicle includes a support structure, a source for electric power, a source of cooling medium, and a vehicle control device. The self-contained axle includes a first side plate removably coupled to the support structure. A second side plate removably coupled to the support structure. A housing coupled to the first and second side plate. An electric motor coupled to the housing and the source for electric power. A motor drive controller unit coupled to the electric motor and to the vehicle control device to communicate signals to the vehicle control device such that one of the speed and torque of the electric motor is controlled based upon the signals. A gear train is mounted in the housing and coupled to the electric motor and an output shaft, wherein, the self-contained axle module can be selectively coupled and decoupled from the support structure. The self-contained axle module can include a first wheel end assembly coupled to the housing in the output shaft and a second wheel end assembly coupled to the housing and the output shaft.

FIG. 1 is a schematic diagram of anelectric vehicle 10 according to an exemplary embodiment. An electric vehicle is a vehicle that uses electricity in some form or another to provide all or part of the propulsion power of the vehicle. This electricity can come from a variety of sources, such as stored energy devices relying on chemical conversions (batteries), stored electrical charge devices (capacitors), stored energy devices relying on mechanical stored energy (e.g. flywheels, pressure accumulators), and energy conversion products. A hybrid electric vehicle is an electric vehicle that uses more than one sources of energy, such as one of the electrical energy storage devices mentioned above and another source, such as an internal combustion engine. By having more than one source of energy some optimizations in the design can allow for more efficient power production, thus one can use power from different sources to come up with a more efficient system for traction. Theelectric vehicle 10 can be used to implement electric vehicles in general and/or hybrid electric vehicles in particular. Theelectric vehicle 10 can implement a number of different vehicle types, such as a fire-fighting vehicle, military vehicle, snow blower vehicle, refuse handling vehicle, concrete mixing vehicle, etc. - In the illustrated embodiment, the
electric vehicle 10 includes anengine 18, agenerator 20, anelectric power converter 24, anenergy storage device 26, a plurality ofelectric motors 28, a plurality ofdrive controllers 30, avehicle controller 34.Electric vehicle 10 optionally includes anenergy dissipation unit 32. Thegenerator 20, thedrive controllers 30, and theelectric power converter 24 are interconnected by a power bus 42, such as an AC or DC power bus.Electric vehicle 10 is generally configured to use a combination of theengine 18 and thegenerator 20 to provide braking capability and to dissipate excess electrical power generated by theelectric motors 28 during regenerative braking. - The
engine 18 is preferably an internal combustion engine, such as a diesel engine configured to both provide mechanical power to thegenerator 20 and to receive mechanical power from generator such that may function as a mechanical engine brake or air compressor. Thegenerator 20 is coupled to theengine 18 and may be configured to function as both generator configured to provide AC or DC power, and as a motor configured to receive electrical power and provide mechanical power to theengine 18. - The
electric power converter 24 is coupled to theenergy storage device 26 and is configured to convert the electrical power generated by thegenerator 20, or by theelectric motors 28 during regenerative braking, to the energy mode required by theenergy storage device 26. For example, according to an exemplary embodiment, the electric power converter is configured to convert AC power generated by thegenerator 20 to DC power and transfer such converted power to thestorage device 26. Theelectric power converter 24 may also convert the energy stored in theenergy storage device 26 back to the energy mode ofgenerator 20 to augment and supplement the power generated bygenerator 20 over the power bus 42. Theenergy storage device 26 may be electric capacitors, electrochemical capacitors or “ultracapacitors,” storage batteries, a flywheel, or hydraulic accumulators. - The
electric motors 28 are appropriately sized electric motors, which may be AC or DC electric motors. Theelectric motors 28 are configured to receive electrical power from the power bus 42 in order to provide a mechanical energy output to a wheel or axle. Theelectric motors 28 are also configured to receive mechanical energy from the wheel or axle during regenerative braking in order to generate electrical power onto the power bus 42. - The
drive controllers 30 are coupled to eachelectric motor 28 and are configured to control the operation of eachelectric motor 28. More specifically, the drive controllers are configured to allow theelectric motors 28 to either receive electrical power from the power bus 42 in order to provide a mechanical energy output to a wheel or axle, or to receive mechanical energy from the wheel or axle during regenerative braking in order to generate electrical power onto the power bus 42. - The
vehicle controller 34 is coupled to theengine 18, thegenerator 20, theelectric power converter 24, and thedrive controllers 30 via adata bus network 76. Thevehicle controller 34 is generally configured to control the operation of theengine 18, thegenerator 20, theelectric power converter 24, theenergy storage device 26, the plurality ofelectric motors 28, and the plurality ofdrive controllers 30. More specifically, thevehicle controller 34 is configured to assist in controlling the distribution of electrical power on the power bus so that the flow of electrical power fromgenerator 20 andengine 18 may be reversed to provide braking capability, and so that excess electrical power generated by theelectric motors 28 during regenerative braking is routed back to thegenerator 20 so that it may be dissipated throughengine 18. - The optional
energy dissipation unit 32 is typically a resistive element through which electrical power generated by theelectric motors 28 during regenerative braking is dissipated as heat if the electrical power exceeds the capacity of theenergy storage device 26. Preferably,electric vehicle 10 is configured such that the excess electrical power generated by theelectric motors 28 during regenerative braking is sufficiently dissipated throughengine 18 andgenerator 20. - In conventional vehicles and particularly in vehicles having a hybrid electric drive, it is often necessary to add support systems such as pressurized lubrication and supplemental cooling systems. Such systems typically are centrally mounted on the vehicle and require the routing of pressurized oil lines throughout the vehicle. The elimination of or limiting the number of such specialized conduit lines being routed through the vehicle, results in additional space for other components and truck parts. A self-contained
axle module 50 for thevehicle 10, which includes alubrication pump 70, theoil filter 72, andheat exchanger 82 at the axle and integrating such components into a self-contained axle module minimizes the conduit routings mentioned above. - A self-contained
axle module 50 can be mounted or coupled to thevehicle 10support structure 12 at any convenient position determined by the manufacturer or user of thevehicle 10. Also, because of the modular configuration, a self-containedaxle module 50 can be easily removed and replaced for maintenance or repairs. The self-containedaxle module 50 only has to be coupled to the source for electrical power such as the principal power unit andgenerator axle module 50 to provide the necessary electrical power to operate theelectric motor 28, as described below. In addition to coupling electric power to the self-containedaxle module 50, a control signal, through adata bus 76 network provides the necessary control and feedback signals for operation of the axle. It is also contemplated that supplemental cooling may be required because of the environment or operating conditions of the self-containedaxle module 50 and therefore supplemental cooling source can also be coupled to the axle. - The self-contained
axle module 50 includes afirst side plate 52 removably coupled to thesupport structure 12 of thevehicle 10. Thesecond side plate 54 is removably coupled to thesupport structure 12. Ahousing 56 is coupled to the first andsecond side plates FIGS. 3-5 .) The side plates can be composed of any suitable material, such as steel, and formed by any convenient and conventional method. Theside plates support structure 12 of thevehicle 10 by bolts, however other means of coupling can be utilized as determined by the user. The positioning of theside plates vehicle support structure 12 is determined by the intended use and operation of thevehicle 10. - The
housing 56 can be composed of any suitable material, such as iron, steel, or aluminum and can be cast and machined as designed by the manufacturer. Thehousing 56 includes a sump portion in the lowest area of thehousing 56. Thehousing 56 in addition to the components described below also houses a gear train 58 which transmits force from theelectric motor 28 to theoutput shaft 60. The gear train 58 may include several types of gears such as planetary gears, sprocket gears, bevel gears or the like with selected gear ratios as determined by the manufacturer and operator of thevehicle 10. - An
electric motor 28 is coupled to thehousing 56 and to the source for electric power. As described above, the source for electric power can be the engine/generator energy storage device 26 as routed through thepower converter 24 and the power bus 42. Control of the power routing is provided through thevehicle controller 34 over thedata bus network 76. - A motor
drive control unit 30 is coupled to theelectric motor 28 and to thevehicle control device 34 to communicate signals to thevehicle control device 34 such that one of the speed and torque of theelectric motor 28 is controlled based upon the signals. Themotor drive controller 30 working in conjunction with thevehicle control device 34 can operate at preset parameters or in response to inputs from an operator typically situated in the cab of thevehicle 10. However, it should be understood that control of the vehicle can be established and maintained outside of thevehicle 10 with a tethered control unit remotely by use of radio frequency signals, infrared signals, or the like. - The self-contained
axle module 50 can be selectively coupled and decoupled from thesupport structure 12 as determined by the operator of thevehicle 10. It should also be understood that the self-containedaxle module 50 can be mounted as illustrated inFIG. 2 wherein two separate self-containedaxle modules 50 are mounted to thevehicle support structure 12 in a tandem arrangement. However, one or both of the illustrated self-containedaxle modules 50 can be rotated 180° relative to thevehicle support structure 12 as such configuration is convenient or appropriate for the intended use of thevehicle 10. It should also be understood that one more or one less self-containedaxle module 50 can be coupled or decoupled from thevehicle support structure 12 as determined by the user or manufacturer of thevehicle 10. - A self-contained
axle module 50 may also include a firstwheel end assembly 62 coupled to thehousing 56 and theoutput shaft 60. A secondwheel end assembly 64 can be coupled to thehousing 56 and theoutput shaft 60. Thewheel end assemblies output shaft 60. The wheel end assemblies may also be coupled to a track, for example, on a bulldozer. - A self-contained
axle module 50 can also include anoil pump 70 mounted inside thehousing 56. Theoil pump 70 and its associated motor is configured to be immersed in oil contained in the sump portion of thehousing 56. (SeeFIG. 6 .) Anoil filter 72 is also mounted on the housing and fluidly coupled to theoil pump 70. Theheat exchanger 82 can also be mounted on thehousing 56 and configured to provide cooling for the interior of thehousing 56, with theheat exchanger 82 fluidly coupled to theoil filter 72 andoil pump 70. Theheat exchanger 82 may also be coupled to the source of cooling medium 36 which may be the oil in the sump portion of thehousing 56 or a supplemental cooling source mounted on thesupport structure 12 of thevehicle 10 with the oil pump submersed in the oil in thehousing 56. Theoil pump 70 may also be used to preheat the oil and axle components. Preheating of the oil and the axle components reduces the stress on the components particularly in cool or cold environments. By mounting the oil cooling and pumping components directly onto thehousing 56 of the self-containedaxle module 50, high pressure oil lines routed through the truck are not necessary thereby providing cost reductions and operational efficiency to the system. - The self-contained
axle module 50 may also include askid plate 80 coupled to the first andsecond side plates FIGS. 3-5 .). - The self-contained
axle module 50 may also include a power take-off (PTO)apparatus 74 mounted on thehousing 56 and coupled to the gear train 58 and a tool 77 (SeeFIGS. 3 and 4 .). The PTO can be used to drive the tool 77, such as a pump 78 to power other equipment associated with thevehicle 10. The PTO can be configured to operate at a speed independent ofwheel 14 speed of thevehicle 10 and dependent on theelectric motor 28 speed or the PTO can be configured to operate at a speed related to bothelectric motor 28 speed andwheel 14 speed. Theelectric motor 28 provides power to the PTO through an associated gear train and can be coupled or uncoupled to theoutput shaft 60 of the self-containedaxle module 50. - It is also contemplated that the
vehicle 10 may also include a plurality ofindependent suspension assemblies 86 which independently suspends one of the wheel end assemblies relative to the vehicle support structure. - For purposes of this disclosure, the term “coupled” means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components or the two components and any additional member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature
