Abstract
The invention relates to a rear suspension system of an electric vehicle. The rear suspension system of the electric vehicle comprises a rear axle. A left trailing arm and a right trailing arm are respectively and movably connected with the rear axle. Rear spiral spring supports are respectively arranged at the two ends of the rear axle. Rear spiral springs are sheathed on the rear spiral spring supports. Rear shock absorbers are arranged at positions where the rear axle is connected with the left trailing arm and the right trailing arm. Compared with the prior art, the rear suspension system of the electric vehicle has the advantages that the structure is simple, the cost is low, the occupied space is small, the shock absorbing performance of the electric vehicle can be effectively improved, and the control performance and the driving comfort are higher.
Description
Technical field
The present invention relates to a kind of battery-driven car rear suspension system.
Background technology
It is power that electronlmobil is meant with the vehicle power, goes with power wheel, meets the vehicle of arteries of communication, the requirement of legislative control on safety each item.Electronlmobil has the waste gas that internal-combustion engines vehicle when work produces, and does not produce exhaust pollution, is very useful to the cleaning of environmental protection and air, almost is " zero pollutes ", and its prospect is extensively had an optimistic view of.
Suspension is the general name of the vehicle frame and all the power transmission connecting devices between vehicle bridge or the wheel of automobile; It mainly acts on is the power of transfer function between wheel and vehicle body; And relax by uneven road surface and pass to the impact load of vehicle body, the vibration that decay causes thus; Guarantee occupant's traveling comfort, reduce the live load of goods and vehicle itself.
How improving the damping effect of battery-driven car, is each manufacturer's urgent problem.
Summary of the invention
The object of the present invention is to provide a kind of battery-driven car rear suspension system, reduce body vibrations, improve travelling comfort.
For achieving the above object; The technical scheme that the present invention adopted is: a kind of battery-driven car rear suspension system; Comprise back axle, left and right trailing arm flexibly connects with this back axle respectively, is respectively equipped with the rear coil springs support at these back axle two ends; Rear coil springs is set on the described rear coil springs support, is provided with rear shock absorber in the junction of back axle and left and right trailing arm.
Be provided with the collar at left and right trailing arm one end, roller is arranged in the collar, the roller bearing that described roller comprises wheel body and is arranged on the wheel body both sides; Be provided with the roller bearing hole that cooperates with above-mentioned roller bearing at the back axle two ends.
Because the employing of technique scheme, the present invention compared with prior art has the following advantages: simple in structure, cost is low, it is little to take up room, and can effectively improve the damping performance of battery-driven car, has higher handling and drives comfort level.
