Abstract
The utility model relates to a special-purpose chassis for an ultra-low floor fuel electric vehicle, which comprises a big beam support, a door type bridge, wheels, a cone pulley reducer, a swing arm torsion bar shock absorber, motors and a power battery box, wherein two pairs of wheels on the front side and the rear side of the chassis are respectively connected through the door type bridge, the door type bridge is connected with the big beam support, double motors are respectively connected with two rear wheels through the cone pulley reducer, and the swing arm torsion bar shock absorber is respectively connected with the door type bridge and the big beam support. The special-purpose chassis for the ultra-low floor fuel electric vehicle has compact structure design, low cost and convenient operation, and has excellent economic benefit.
Description
Technical field
The utility model relates to a kind of chassis, particularly relates to a kind of super-low floor pure electric vehicle chassis special.
Background technology
Along with constantly bringing forth new ideas of urban construction, having hommization more, intelligentized facility is the trend of future city development.The super-low floor passenger vehicle has characteristics such as the chassis is low, ride comfort, HOP ON, greatly facilitates the passenger of discomfort in riding.The super-low floor passenger vehicle costs an arm and a leg, makes complexity, also can't be extensive use of as urban transportation tool at present.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design, lower-cost super-low floor pure electric vehicle chassis special are provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of super-low floor pure electric vehicle chassis special, comprise big boom support, gate-type bridge, wheel, cone pulley retarder, swing arm torsion bar bumper, electrical motor and power battery box, connect by the gate-type bridging respectively between two pairs of wheels of side before and after the chassis, the gate-type bridge links to each other with big boom support, double motor is connected with two rear wheels respectively by the cone pulley retarder, and swing arm torsion bar bumper links to each other with big boom support with the gate-type bridge respectively.
Described power battery pack is arranged in the middle front part on chassis.
Described rear wheel adopts wide tire single-wheel.
Compared with prior art, the beneficial effects of the utility model are:
1, adopt double-motor by driving two rear wheels, back axle adopts the gate-type beam, can thoroughly open the passage of trailing wheel, power battery pack is arranged under the passenger-seat of the interior middle part of car, do not take the space, chassis, play the effect of symmetrical load simultaneously, solved a difficult problem that runs into when conventional truck is designed to super-low floor
2, trailing wheel adopts wide tire single-wheel and trailing wheel passage to open fully,, further widened the trailing wheel passage.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of super-low floor pure electric vehicle chassis special, as shown in Figure 1, comprise big boom support 1, gate-type bridge 2, wheel 3, cone pulley retarder 4, swing arm torsion bar bumper 5, electrical motor 6 and power battery box 7, connect by gate-type bridge 2 respectively between two pairs of wheels 3 of side before and after the chassis, gate-type bridge 2 links to each other with big boom support 1, electrical motor 6 is connected with rear wheel 3 by cone pulley retarder 4, and swing arm torsion bar bumper 5 is positioned at chassis head 8 places, and links to each other with big boom support 1 with gate-type bridge 2 respectively; Power battery box 7 is arranged in the middle front part on chassis, and the effect of symmetrical load is arranged.Both sides, rear portion, chassis are respectively equipped with an electrical motor 6, and each electrical motor 6 is corresponding with a chassis rear wheel 3, moves ahead with powered vehicle.It is anterior and be connected with gate-type bridge 2 on the front vehicle wheel 3 that swing arm torsion bar bumper 5 is arranged on the chassis, plays the effect of damping.Chassis rear wheel 3 adopts wide tire single-wheel, makes that the vehicle counterweight is even.
The resulting super-low floor pure electric vehicle of the utility model chassis special, adopt double-motor to drive two rear wheels 3 respectively by the cone pulley drop-gear box, back axle adopts the gate-type beam, can thoroughly open the passage of trailing wheel, power battery box 7 is arranged under the passenger-seat of the interior middle part of 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 battery-driven car.
