Title:
METHOD AND SYSTEM FOR ADJUSTING HEIGHT OF SUSPENSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/073652
Kind Code:
A1
Abstract:
A method and a system (100) for adjusting a height of a suspension system. The system comprises: arranging a pneumatic valve (130) and an air spring (140) between a first connecting part (110) and a second connecting part (120), wherein the positions of the pneumatic valve (130) and the air spring (140) are adaptive to each other; connecting the gas output end of the pneumatic valve (130) with the gas input end of the air spring (140); the pneumatic valve (130) collecting, at least one motion variable, relative to the second connecting part (120), of the first connecting part (110); and meanwhile, making the pneumatic valve (130) change its own operation stroke according to the collected motion variable and/or a change in motion variable, so as to connect the air spring (140) with a gas source generating gas flow to inflate the air spring (140), or connect the air spring (140) with an atmosphere to generate gas flow therebetween to deflate the air spring (140) and adjust the height.
