Description

Description A PARALLEL HYBRID VEHICLE
[001] Technical Field
[002] This invention relates to parallel hybrid vehicles.
[003] Prior Art
[004] The environmental pollution caused by waste gases and the greenhouse effect, the decreasing fossil petrol reserves and thus the increasing petrol costs have forced automobile producers to find solutions different than internal combustion engine. As these vehicles utilize any kind of resources, such as solar power, wind power, hydrogen etc., which can be used in electrical energy production, their dependence on fluid fossil fuels is diminished. On the other hand, the weight and the low performance of the batteries hinder the expected demand for the electrical vehicles. Therefore, hybrid vehicles which combine two different power supplies have been taken into consideration.
[005] Hybrid vehicles which are powered by an internal combustion engine and an electrical engine are becoming widespread. These vehicles can be fundamentally classified in two groups: a) an internal combustion engine actuates a generator, and this generator charges the batteries or actuates an electrical motor which is connected to a transmission assembly. Consequently, internal combustion engine and an electrical motor operate by being connected serially, b) a fuel tank and an internal combustion engine are connected to a transmission assembly from one line and an electrical motor is connected to a transmission assembly from a separate line which is parallel to the former.
[006] Many parallel hybrid vehicle applications are known in the art. One of these is the United States patent application US5713425, wherein an internal combustion engine and an electrical motor which are connected to the traction axle of the vehicle by means of the same transmission assembly. In the United States patent US6110066, an electrical motor/generator and an internal combustion engine which are connected to the axle by means of the same gear box. In the British patent GB2386879, a similar embodiment is disclosed. Moreover, in United States patents US6026921, 6308794, 6307276, the British patents GB2367795, 2374844 and the European patent EP1232891, an electrical motor and an internal combustion motor is connected initially to another and later to a connection coming out of one of them.
[007] In the parallel hybrid vehicles present in the aforementioned two groups, an internal combustion engine and an electrical motor actuate the same tires by means of a mechanic transmission assembly. The batteries are charged when the electrical motor is not used or during regenerative braking. However, utilizing extremely complex transmission assemblies in order to transfer the motion coming from the two power supplies to the axle became necessary. Moreover, the drive of the vehicle is ensured solely by the two tires at the end of the axle which is connected to the transmission assembly.
[008] As disclosed in the United States patent US4438342, it is possible to connect each power supply to the separate pair of tires in order achieve more drive. However, in the embodiment disclosed herein, an alternator which is powered by an internal combustion engine is used for charging the battery and the alternator feeding the electrical motor by deactivating the batteries operating at normal power mode is envisioned.
[009] In all of the aforementioned embodiments, as the electrical connections between the electrical motor and the internal combustion engine and also the mechanical connections between the internal combustion engine and the electrical motor require many intermediate pieces and transmission elements, it is necessary to design the entire components from the very beginning. And this prolongs the process of preparing the project and increases product cost due to the transmission elements.
[010] Apart from these, it is possible to convert current internal combustion engine vehicles to hybrid vehicles.
[011] In addition, the vehicle can carry on proceeding without stopping even if one of its motors breaks down due to the mechanical and electrical connections present in between.
[012] Brief Description of the Invention
[013] The object of this invention is to realize a hybrid vehicle which does not comprise complex transmission assemblies.
[014] An object of this invention is to realize a tire drive (4x4) hybrid vehicle.
[015] Another object of this invention is to realize a hybrid vehicle which can be adapted to internal combustion engine vehicles which already exist or which are to be produced.
[016] In the hybrid vehicle realized in order to attain the objects of this invention, an electrical motor and an internal combustion engine, unlike the prior arts, are connected independently from each other to the separate pair of tires. There is no electrical or mechanical connection between the electrical motor and the internal combustion engine. The electrical motor can also operate as a generator and the batteries are charged with the rotational movement transmitted to the electrical motor by the tires via an axle during the motion of the vehicle by means of an internal combustion engine. Front and rear drives are obtained when both of the motors are actuated simultaneously.
[017] A Detailed Description of the Invention [018] The hybrid vehicle realized in order to attain the objects of this invention is illustrated with the accompanying figures; wherein,
[019] Figure 1 - is a schematic view of the prior art parallel hybrid vehicle;
[020] Figure 2 - is a schematic view of the said hybrid vehicle;
[021] Figure 3 - is a schematic view of another embodiment of the said hybrid vehicle;
[022] Figure 4 - is a schematic view of another embodiment of the said hybrid vehicle.
[023] The components in the figures have each been numbered corresponding the following: 1. Hybrid vehicle 2. Tire 3. Axle 4. Internal combustion engine 5. Electrical motor/Generator 6. Fuel tank 7. Battery 8. Power management mechanism
[024] The inventive hybrid vehicle (1) comprises at least two axles (3 a and 3b) which connect together the vehicle tires (2) two at a time and at least one internal combustion engine (4) which is connected to one of these axles (3 a); and characterized with at least one electrical motor/generator which is connected to the other tires (2c and 2d) by being electrically and mechanically independent from the internal combustion engine.
[025] In the embodiment of the invention illustrated in Figure 2, an electrical motor/ generator (5) is connected to a second axle (3b). Thus, the internal combustion engine actuates only one of the tire pairs (2a and 2b) (front or rear) and the electrical motor actuates only the other tire pair (2c and 2d). The internal combustion engine (4) is connected to the fuel tank (6). The electrical motor (5) is connected to the battery (7) by means of a power management mechanism (8). The movement generated by the electrical motor (5) is transmitted to the tires (2c and 2d) by means of a differential. On the other hand, charging of the battery is ensured by the rotational movement transmitted from the tires to the electrical motor when the vehicle is driven solely with the internal combustion engine or when the brakes are used. In this embodiment, the control mechanism has a simpler and a more economic structure as there is one electrical motor (5) and a power management mechanism (8).
[026] In the aforementioned embodiment, in the Figures 3 and 4 of the invention, two electrical motors/generators (5) are connected to the tires (2c and 2d) separately in order to overcome the possible tightness in the layout that could arise when the movement is transmitted to the tires (2c and 2d) by means of a differential. In this embodiment, each electrical motor/generator can be connected to a common battery (7) through a separate power management mechanism (Figure 3) and also it is possible to connect it to separate batteries (7) through separate power management mechanisms (8). In both of these embodiments, layout problems can be overcome when two motors with smaller dimensions and less capacity is used instead of a big electrical motor. However, the mechanical connections realized separately on each tire can have simpler structures.
[027] In the preferred embodiment of the invention, the internal combustion engine (4) is connected to the front axle (3 a) and the electrical motor is connected to the rear axle (3b). However, it is also possible to make the direct contrary connections.
[028] The inventive hybrid vehicle is disclosed above with the accompanying figures and examples in order to provide a more clear understanding, however it cannot be restricted with these examples. The scope of the invention is principally as stated in the claims.
