Technical field
The utility model relates to the two transverse arm active suspension of a kind of vehicle, especially adopts Direct wheel drives system and motor has two transverse arm active suspensions of energy regenerative effect as actuator.
Background technology
That vehicle suspension is mainly divided into is passive, half initiatively and active suspension three major types.Passive suspension because of structure simple, cost is lower, is widely adopted, but can only compromise in certain specific road surface and speed during design and be issued to optimal performance.Semi-active suspension structure is relatively simple, advantage of lower cost, according to road surface and speed of a motor vehicle change adjustment suspension damping, can improve suspension property to a certain extent.Active suspension can provide different active forces under different road surface and the speed of a motor vehicle, its essence is equal to rigidity and the damping of adjustment suspension in real time, at utmost can improve suspension property, but because of complex structure, energy consumption and cost higher, its application and promote be subject to very large restriction.
Tradition active suspension often adopts the form of air bellow or hydraulic actuator, the energy input that its need of work is huge, and this, in today of discharge and power conservation requirement increasingly stringent, shows inapplicable.Energy Hydraulic-active Suspension complex structure, and the hydraulic energy obtained by vibration feedback is difficult to storage and application.And orthodox car battery tension is low-yield little, the development of Active suspension is subject to severely restricts.In today that new-energy automobile is greatly developed, high-tension battery can provide suitable energy source for electric actuator, and simultaneously can as the storage element of electric actuator regenerative electric energy.Therefore, Active suspension causes and studies interest widely.
The form of Active suspension actuator mainly contains linear motor type, motor and pinion and-rack and motor and Ball screw type.Linear motor type active suspension structure is relatively simple, but actuator volume is relatively large, and high-performance electric motor-car often adopts distributed form of taking turns limit or wheel hub driving, and wheel limit arrangement space is limited.Motor and pinion and-rack are inadequate because of rack-and-gear over-speed gear ratio, often need other speed increasing mechanisms, or adopt larger motor.Ball screw has higher positive drive efficiency and inverse driving efficiency, the motor matched with it can adopt the high power density motor that the little rotating speed of volume is high, but especially adverse efficiency is still a little less than gear transmission for the driving efficiency of ball screw, and a whole set of actuator size is also larger.In addition, the structure design of these active suspensions is applied to McPherson suspension more, and active suspension is usually used in High Performance luxury car, and double wishbone suspension enjoys favor because its ideal for wheel alignment parameter controls.
