Abstract

The invention discloses a vertical translation spatial multi-connecting-rod individual suspension rack, which comprises the following parts: vehicle bulk or rack, front swinging arm, front swaying arm, vertical mobile arm, back swinging arm and back swaying arm, wherein the middle through-hole is set on the center flat of vertical mobile arm of back suspension rack, the static main-pin inner-incidence and main pin shaft cylinder are set on the middle flat of vertical mobile arm of front suspension rack along vertical direction, the left and right suspension ears on two ends of vertical mobile arm are not on the same plane without paralleling, which parallel two intersection lines of middle flat, the axial line of rotary spoke A, B and C of mobile chain ABC parallels mutually, which is vertical of the plane decided by connecting rod AB and BC, the axial line of rotary spoke F, E and D of mobile chain FED parallels mutually, which is vertical of the plane decided by FE and ED, the separation angle of the plane of AB and BC and plane of FE and ED equals the separation angle of plane of left and right suspension ear.

Description

technical field [0001] The invention relates to an automobile suspension system, in particular to a space multi-link independent suspension system, and belongs to the field of automobile engineering. Background technique [0002] From the point of view of mechanics, the suspension and the steering system are both spatial multi-link mechanisms, and their performance determines the handling stability and ride comfort of the car to a large extent. Suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel). Its functions mainly include: ① Easing the vibration caused by the impact caused by the uneven road surface. With suitable damping performance, the vibration frequency of the car is low and the vibration attenuation is fast. Ensure that the car has good ride comfort and the vibration acceleration experienced by the occupants does not exceed the limit value of international standards. ② It can...
