Abstract
The utility model discloses a special chassis of ultra lower floor pure electric vehicle, which comprises a crossbeam bracket, a portable type bridge, wheels, a pulley cone reducer, a swinging arm torsion bar absorber, electric motors and a power battery pack. Wherein, the wheels are connected with the crossbeam bracket through the portable type bridge; the double electric motors are connected respectively with two rear wheels through the pulley cone reducer in a transmission manner so as to drive the vehicle to move forwards. The utility model can open thoroughly the channel of the rear wheels, and the power battery unit is arranged in the underground below the passenger seats in the middle of the vehicle, which does not take up the space of the chassis, and has an effect of balancing the load, thus solving thoroughly the difficulties of designing the traditional vehicle into ultra low floor, in addition, the utility model can fully realize localization, which makes the construction cost cheap; the channel of the rear wheel can be opened fully, which plays an active and practical meanings to the further development of the electric motor coach.
Description
Technical field
The utility model relates to a kind of passenger-carrying chassis, particularly a kind of super-low floor pure electric vehicle chassis special that is used for electrobus.
Background technology
The passenger vehicle of super-low floor (one-level is marked time, height off the ground 360mm) is the developing direction of future city passenger vehicle, also can't produce but the front and back bridge of super-low floor passenger vehicle is domestic, has only import or joint product, costs an arm and a leg.In addition, traditional fuel vehicle of super-low floor is owing to be subjected to the restriction of intrinsic space and traditional vehicle transmission principle, and the mechanical layout on chassis and electric wiring are all very difficult, causes the passage of back wheel location to be difficult to open simultaneously, has influenced interior space greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of chassis structure simple, rationally distributed super-low floor pure electric vehicle chassis special for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the super-low floor pure electric vehicle chassis special that the utility model is designed, it mainly comprises big fine strain of millet support, gate-type bridge, wheel, cone pulley retarder, swing arm torsion bar bumper, electrical motor, power battery box, and wheel links to each other with big boom support by the gate-type bridge; Double motor is in transmission connection with two rear wheels respectively by the cone pulley retarder, moves ahead with powered vehicle; Swing arm torsion bar bumper links to each other with gate-type bridge and big boom support and plays the effect of damping; Power battery pack is arranged in the middle front part on chassis, plays the effect of symmetrical load; Because the vehicle counterweight is even, rear wheel adopts wide tire single-wheel.
The resulting super-low floor pure electric vehicle of the utility model chassis special, adopt double-motor to drive two rear wheels respectively by the cone pulley drop-gear box, back axle adopts the gate-type beam, can thoroughly open the passage of trailing wheel, passenger-seat was underground in the middle part of power battery pack was arranged in the car, do not take the space, chassis, play the effect of symmetrical load simultaneously.This super-low floor pure electric vehicle chassis special can thoroughly solve a difficult problem that runs into when conventional truck is designed to super-low floor, owing to can realize production domesticization fully, makes low cost; The trailing wheel passage can be opened fully, by 600mm can broadening to 1100mm; Because counterweight is reasonable, trailing wheel can adopt wide tire single-wheel, has further widened the trailing wheel passage.It has very active operation significance to further developing of electrobus.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment:
