Less than the vertical line distance of described motor from described battery pack, and the axial line of described motor is higher than the axial line of described back axle to described motor from the vertical line of described back axle distance.
Described DC conv is installed in a side of described electric machine controller.
Be separately installed with forward and backward bridge shock absorber and forward and backward bridge steel spring on the described forward and backward bridge.
The front end of described crossbeam assembly is equipped with foresteerage gear, and the rear end of described crossbeam assembly is installed with spare tyre holder.
The utility model has following advantage with respect to prior art:
At first,, can play a very good protection to battery pack on the one hand, prevent stolen and hit, increase safety, also can simplify the laying of circuit on the other hand, avoid the loss of electric weight by battery pack being concentrated the inboard be arranged on chassis two longitudinal girders.
Secondly, the postposition of actuating device makes motor obtain simplifying to the intermediate drive link between the back axle, thereby reactive power consumption and the transmission fault that can effectively check mechanical transfer, and then the transmission efficiency of raising drive motor and the reliability of transmission, simultaneously also can alleviate complete vehicle weight, electric energy is rationally utilized.
Once more, the reasonable Arrangement of built-in and other members of the postposition of actuating device, battery pack makes that the forward and backward load in chassis is even, the positive and negative 20kg that is no more than of four-wheel.
At last, by to the aforesaid many optimization of chassis structure, make pure electric automobile can maximize, the most reasonable, utilize the electric energy of battery pack most effectively, improve the continuation of the journey mileage of vehicle.
Description of drawings:
Fig. 1 is the plan structure scheme drawing on the utility model pure electric automobile chassis.
The specific embodiment:
Referring to Fig. 1,, comprise propons 1, back axle 2, car beam assembly 3 and be installed in battery pack 4, DC conv 5, actuating device 6 on the car beam assembly according to the pure electric automobile chassis structure that the utility model provides.Car beam assembly 3 comprises two longitudinal girders 31 and some crossbeams 32 that these two longitudinal girders are connected as one, and adopts riveted joint between crossbeam 32 and the longitudinal girder 31, so that assembly and disassembly.Battery pack 4 and actuating device 6 are installed in the inboard of two longitudinal girders 31, wherein, actuating device 6 is near back axle 2 settings and be used for driving rear axle, battery pack 4 is installed between actuating device 6 and the propons 1, and for back axle 2 or actuating device 6, battery pack 4 more is partial to propons 1 and is provided with, with the forward and backward weight in balance chassis.And, preferably 2/3~5/6 position of battery pack 4 is arranged on the front position of longitudinal girder 31 longitudinal centerlines as a kind of optimal way, promptly battery pack 4 only has 1/3~1/6 portion to be positioned at the back-end location of longitudinal girder longitudinal centerline.
