SUSPENSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/045097
Kind Code:
A1
Abstract:
When the travel state of a vehicle is a roll state, by exchanging compressed air between front-wheel left and right air suspensions by means of a compressor and exchanging compressed air between rear-wheel left and right air suspensions by means of a compressor, the left and right front wheel air suspensions and the left and right rear wheel air suspensions each independently generate reverse roll. As a result, it is possible to perform height control of the left and right front wheel air suspensions in parallel with height control of the left and right rear wheel air suspensions, and it is possible to improve the responsiveness of reverse roll control.
