SUSPENSION SYSTEM FOR A DRIVER'S COMPARTMENT OF A VEHICLE

摘要

A suspension system for a driver's compartment on a vehicle chassis is provided, comprising a mounting arrangement for mounting the driver's compartment on the vehicle chassis including at least two pneumatic springs to be arranged along a lateral side of driver's compartment and coupled between the driver's compartment and the vehicle chassis. For each pneumatic spring a pressure sensor and a deflection sensor are provided, measuring a spring pressure and spring height respectively. For each pneumatic spring a valve device is communicatively coupled to a pressure supply; a vent and a respective pneumatic spring. A continuously variable force setpoint can be set that defines a pressure difference between an inlet and outlet terminal and a controller is provided for setting a force setpoint of the valve by powering the actuator based on a reference derived from a electronic vehicle control system (ECU) irrespective of mass flow and temperature.
