Title:
MECHANICAL ACTIVE SUSPENSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/093693
Kind Code:
A1
Abstract:
A vehicle mechanical active suspension mechanism. The upper ends of each damping spring (5) and each shock absorber (6) in a suspension are connected to a worm gear swing arm (7), and then the worm gear swing arm is connected to a vehicle body by means of a worm-and-gear mechanism. An ECU controls a servo motor (9) to drive each worm (8) to rotate so as to drive the worm gear swing arm (7) and the suspension connected thereto to generate a lifting motion relative to the vehicle body, thereby realizing the height adjustment of the vehicle suspension. A lever member (12) is used to adjust a fulcrum of an upper wishbone (4) of a transverse double wishbone suspension relative to the vehicle body, thereby solving the problem of excessive wheel inclination change during the lifting of the suspension; a novel four-bar Y-shaped longitudinal swing arm is employed to improve the supporting performance of the suspension; a braking mechanism is provided in the middle of an anti-roll bar, and the disconnected anti-roll bars are combined by a dog clutch (18), thereby overcoming defects of anti-roll bars in conventional suspensions and further improving performance thereof.
