2.7 large sedan-chairs are broadening 500mm on the basis of 3 large sedan-chairs, increases 1000mm, adds 4 seats.
According to the design concept of " light, little, simple, just, economize ", large sedan-chair has following great change compared with roadlice in layout:
1, front row only has one and occupy middle and drives seat! This is the large feature that the large sedan-chair of the present invention is different from roadlice, why dare to do like this, be because: the power system of (1) large sedan-chair has really accomplished " the simplest ".The power system of large sedan-chair only has: several assemblies such as two consubstantiality motors, lithium cell, speed governing and braking power module, E-Diff, it does not have power-transfer clutch, diff, retarder, change speed gear box and selector thereof and " automatic transmission " etc. these for parts usually indispensable roadlice; In addition, large sedan-chair is " battery-driven car " inherently, and it does not need separately to establish the starter motor for roadlice startup and storage battery.(2) because the assembly of power system is few and have local pendulum.As: lithium cell to be placed in the battery compartment of large sedan-chair bottom, by the direct frame of two consubstantiality motors on two trailing wheels, speed governing and braking power module are placed in driving console, the position of E-Diff is first-class at the connecting rod of bearing circle, therefore large sedan-chair is just eliminated long " headstock " that protrude from roadlice front portion absolutely, driving seat reach between two front-wheels.
2, back seat is positioned on trailing wheel and two consubstantiality motors.This is another large feature that the large sedan-chair of the present invention is different from roadlice.Large sedan-chair eliminate three railway carriage or compartment roadlices be positioned at car after " boot ", and under trailing wheel has been advanced to back seat straight, chat the headstock removed before adding, like this, large sedan-chair shortens the length more than 2 meters fully compared with three railway carriage or compartment roadlices.Thus enable 3 large sedan-chairs at long 2300mm, wide 1300mm, only and the area of three railway carriage or compartment roadlices 2/5ths has been laid two row three seats; Enable 5 large sedan-chairs when taking advantage of manned number identical, area of conter only has 54.17% of three railway carriage or compartment roadlice areas of conter (the wide 1800mm of long 4400mm); Enable 7 large sedan-chairs at long 3300mm, wide 1800mm, in even also short than three railway carriage or compartment roadlices plane, arrange seven seats.
3, two row's seats only have " two ", and this is the another large feature that large sedan-chair is different from two row's seats " four " roadlice.Although without " boot ", large sedan-chair drive the place (3 large sedan-chairs and 5 large sedan-chairs) that wide 300mm, long 600mm have been vacated in a both sides; Or wide 550mm, long 600mm place (4 large sedan-chairs and 7 large sedan-chairs), on the one hand, this ground can for depositing object, to make up the inconvenience brought because having lacked boot temporarily; On the other hand, this place is seen away from back row seats (3 large sedan-chairs and 4 large sedan-chairs) or middle row seat position (5 large sedan-chairs and 7 large sedan-chairs), drive a both sides to have no small " space ", therefore, though 3 large sedan-chairs and 4 large sedan-chairs have two arrange seatses, but " two " can be designed to, though and 5 large sedan-chairs and 7 large sedan-chairs have three arrange seatses also can be designed to " four ".These are all because " front row only have one and occupy middle drive seat " " facility " of bringing undoubtedly.Certainly, though 3 large sedan-chairs and 4 large sedan-chairs " short ", also or " four " can be designed to.Therefore, all do not give about " door " accompanying drawing of large sedan-chair and illustrating.
4, in addition, conveniently drive and get on and off, driving that seat needs to be designed to simultaneously can forward and backward movement and turning left and right, and this is also the place that large sedan-chair is different from that roadlice drives seat.
The power system of large sedan-chair and the power system of general battery-driven car different:
1, the power of large sedan-chair is taked " with double engines ", and this is the feature that large sedan-chair is different from general battery-driven car.With double enginesly bring following advantage: (1) can get rid of the large and mechanical differential gear box of heaviness, replace simple, small and exquisite and " E-Diff " of cheapness; (2) be conducive to saving local and alleviating deadweight; (3) be conducive to improving car load efficiency; (4) even if an engine damages also be unlikely to " casting anchor ", be equivalent to for large sedan-chair adds one " double insurance ".
What 2, " with double engines " of large sedan-chair adopted is " two consubstantiality motors " structure, be placed among same steel pipe by two motors, its benefit is: the installation of (1) motor is considerably simplified, only need by direct for the shaft extension of two motors frame on two trailing wheels; (2) vehicle body can be directly installed on motor steel pipe simply by bumper, with simplified structure and saving cost.
3, two consubstantiality motor rated powers of large sedan-chair are equal, and motor type is all " series machines of 3 times of electric currents, 4.5 times of moments of torsion ", and this is the important feature of the large sedan-chair power of the present invention.Why large sedan-chair will adopt traditional " series machine " to be because the speed adjusting performance that there is no a kind of motor so far can match in excellence or beauty with it.
4, due to the function of voltage " moment of torsion to be the function of electric current and rotating speed be " of " series machine ", therefore objectively need, for its coupling one has the speed governing power source of " power stabilize " character, just can give full play to its excellent speed adjusting performance.So-called " power stabilize speed governing power source " refers to the large power supply that electric current and voltage all can adjust from zero to specified peak bidirectional linear, the speed governing power source part during Here it is described " speed governing and braking power module ".About " speed governing and braking power module ", the present inventor submits separate case to patent application.
Large sedan-chair adopts lithium cell as electrokinetic cell without exception.It is reported: the gravimetric specific energy of China's lithium cell has been accomplished at present: 137wh/kg.As the gravimetric specific energy getting lithium cell is: 120wh/kg; The ton-kilomiter energy consumption of getting large sedan-chair is: 70wh/tkm, and lithium cell accounting course continuation mileage sees the following form:
Note 1: " accounting " refers to that lithium cell accounts for the ratio of battery-driven car gr.wt..In the dimension that this " battery-driven car gr.wt. " is random.
Note 2: as can be seen from the table, along with lithium cell accounting strengthens, the course continuation mileage of battery-driven car is also larger, but battery-driven car will stress load carrying ability, as excessive in lithium cell accounting, just becomes the car of fortune battery.
Course continuation mileage is generally designed to be no less than 150km by large sedan-chair, and lithium cell about needs to take 10% of load carrying ability.Gr.wt. as 3 large sedan-chairs is 750kg, and lithium cell accounts for 10% for 75kg, and course continuation mileage can reach more than 150km.The rest may be inferred by analogy: the gr.wt. of 4 large sedan-chairs is 1000kg, and lithium cell accounts for 10% for 100kg; The gr.wt. of 5 large sedan-chairs is 1250kg, and lithium cell accounts for 10% for 125kg; The gr.wt. of 7 large sedan-chairs is 1750kg, and lithium cell accounts for 10% for 175kg.As special requirement, also suitably can strengthening the accounting of lithium cell, to improve course continuation mileage, but should consider suitably reduce load-carrying or suitably increase power of motor when implementing.
After the gr.wt. of large sedan-chair and " modulus " (modulus of large sedan-chair is: 250kg/ people) are determined, the body weight of people is in average 75kg, the payload-weight ratio that just can calculate large sedan-chair is: 75/175=42.85%, exceeds nearly 18 percentage points than the payload-weight ratio (5x75kg/1500kg=25%) of general three railway carriage or compartment roadlices.
The gravimetric specific energy of lithium cell is in 120wh/kg, the 75kg lithium cell gross horsepower of 3 large sedan-chairs is 9kw, and take 6 hour rate chargings, the power of charger needs 1.5kw, the ammeter of general family can afford to bear, and therefore 3 large sedan-chairs are suitable for individual and nuclear family's use.The like: the 100kg lithium cell gross horsepower of 4 large sedan-chairs is 12kw, take 6 hour rate chargings, the power of charger needs 2kw, general family's ammeter also can afford to bear, therefore 4 large sedan-chairs are except being applicable to individual, nuclear family, are also suitable as taxicar and use, be used as the taxicar used time, suitably can strengthen lithium cell accounting and amplify power of motor, should " customize " if desired; The 125kg lithium cell gross horsepower of 5 large sedan-chairs is 15kw, and take 6 hour rate chargings, the power of charger needs 2.5kw, and the ammeter of general unit can bear, and therefore 5 large sedan-chairs are suitable as officer's car; The 175kg lithium cell gross horsepower of 7 large sedan-chairs is 21kw, and take 6 hour rate chargings, the power of charger needs 3.5kw, and the ammeter of general unit also can bear, and therefore 7 large sedan-chairs are also suitable as officer's car.
The F-Zero of large sedan-chair is set to: fully loaded 80km.Due to series machine in theory " no load speed trends towards infinity ", therefore, the underloading speed per hour of large sedan-chair may reach more than 100km.
The climbable gradient of large sedan-chair is set to: 8-9 degree.It normally travels by " rating horsepower " with double engines, starts, climbs that what then lean on is two consubstantiality motors " 3 times of electric currents, 4.5 times of moments of torsion ".
Finally, large sedan-chair is the same with other battery-driven car, also has the systems such as manipulation, damping, brake, instrument, instruction, and this specification sheets does not describe as " feature ".
The embodiment of the large sedan-chair of the present invention can have various combination and other embodiment, and all technical schemes taking equivalent replacement or equivalent transformation to be formed, all drop on the protection domain of application claims.
