汽车车轮五点悬挂是汽车车轮独立悬挂的一种广义体现。车轮支架通过布置在空间的五根不同长度的连杆的球铰链与底盘空间接点相连。在一般情况下能区分相应于车轮弹簧运动和转向运动的两个运动自由度。其它结构的独立悬挂可以看作是五点悬挂的特殊情况。斯图加特大学力学A研究所使用空间机构试验方法,对五点悬挂的刚体运动学进行了完整的模型分析研究。一方面研究车轮架的微分运动和有限运动,另一方面也研究速度和加速度,并用计算机解约束方程。此外,可以直接算出在汽车底盘设计中所需要的结构参数,如车轮外倾角、前束、主销后倾角和主销内倾角。
Five-wheel car wheel suspension is a kind of vehicle independent suspension of a broad manifestation. The wheel brackets are connected to the chassis space contacts by ball joints of five different length links arranged in space. In general it is possible to distinguish between two degrees of freedom of movement corresponding to the wheel spring movement and the steering movement. Independent suspension of other structures can be seen as a special case of five-point suspension. The Mechanics A Institut of Stuttgart University used the method of space agency test to conduct a complete model analysis of rigid body kinematics at five-point suspension. On the one hand, we study the differential and finite motions of the wheel carrier, on the other hand, we also study the velocity and acceleration, and use the computer to solve the constraint equations. In addition, structural parameters such as wheel camber, toe-in, kingpin caster and kingpin camber can be calculated directly for the chassis design of the car.
