Description
Technical field
Suspension system is turned to the invention belongs to vehicle technology field, more particularly to electric vehicle hub.
Background technology
Conventional fuel oil car brings many negative effects to ecological and environment, therefore, the continuable electric energy of clean and effective is posted
Give great expectations.Under this upsurge, lifting vehicle electrical gasification level reduces dependence being total to as auto industry to conventional ADS driving technology
Know, wherein wheel hub motor is become to realize that the vision provides a great potential approach.Wheel hub motor technology changes traditional vapour
The pattern of car engine centralized driving drives for distributed, realizes that wheel independently drives by installing wheel hub motor additional in wheel
Dynamic and steering, eliminates huge and complicated engine and transmission system, there is great simplification in structure, achievable driving,
Braking, the coordination control for turning to, so as to possess more preferable handling.However, the lateral dimension of motor is larger, meeting is installed in wheel
The arrangement space of heavy compression suspension and knuckle, causes and is difficult to obtain preferable suspension positional parameter, thus trigger suspension with
The adaptation issues of Electric Motor Wheel, wherein it is excessive caused to be primarily due to scrub radius；Motor causes unsprung mass excessively heavy simultaneously, tire
Adhesion effect on ground can also be deteriorated.If continuing to use the suspension frame structure of conventional truck, vehicle control stability is inevitably resulted in
With the severe exacerbation of ride performance, or even cause the kinematics of chassis structure to be interfered, produce Exploration on Train Operation Safety.Therefore, pin
Suspension design and the just aobvious urgent and necessity of exploitation to wheel hub motor feature.
Preferable motor turning control is simultaneously around a certain based on all wheels of Ackermann steering model, i.e. automobile
Pivot does pure rolling, can thus avoid the slip between tire and ground from wearing away, and its fact also indicates that the mill of tire
Sliding friction when mostly turning to is damaged to cause；Make all wheels simultaneously while do pure rolling around a pivot, can be with
It is prevented effectively from the rollover of vehicle, throws away the accidents such as road, so as to lifts manipulation stability and security.Preferable Ackermann steering
Model needs four-wheel independently can be turned to significantly, and if wheelspan moment between tire ground contact patch center keep constant, can
To avoid introducing compensation operation.Zero turn radius suspension may insure tire ground contact patch centre wheel away from being definite value, but its stub cloth
