ACTIVE VEHICLE SUSPENSION SYSTEM |
摘要 |
An active vehicle suspension employs a multi-point support system between a vehicle's chassis and cab. Each support point has an isolator which includes a linear hydraulic actuator (52) that is connected at its quiet end to the payload by a passive vibration isolator (62) and is connected at its vibrating end to the chassis. Each isolator also has a support spring (68) to off-load the majority of the weight of the cab from the hydraulic actuator. An accelerometer (78) is mounted to sense movement at a point between the linear hydraulic actuator and the passive vibration isolator. An electrical signal produced by the accelerometer is processed to operate a hydraulic valve (26) that controls movements of the hydraulic actuator so that transmission of vibrations from the chassis to the cab is attenuated. |
