Document Type and Number:
WIPO Patent Application WO/2021/073653
Kind Code:
A1
Abstract:
A method and system for adjusting height and damping force, the method comprising: between a first connection part (110) and a second connection part (120), arranging a pneumatic valve (130), an air spring (140), an adjustable damper (150) and a damping force adjusting device (160) used for adjusting the damping force of an adjustable damper (150), the positions of the pneumatic valve (130), the air spring (140), the adjustable damper (150) and the damping force adjusting device (160) being adaptive and the the pneumatic valve (130) being connected to the damping force adjusting device (160) and the air spring (140), respectively; the pneumatic valve (130) collects at least one movement variable of the first connection part (110) relative to the second connection part (120); meanwhile, the pneumatic valve (130), according to the collected movement variable and/or the change in the movement variable, controlling the air spring (140) to inflate or deflate so as to implement height adjustment; and/or carrying out air driving on the damping force adjusting device (160) to control the adjustable damper (150) to output corresponding damping force, so as to adjust the size of the damping force of the adjustable damper (150), which improves the sensitivity of height adjustment and damping force adjustment.
