Description
Technical field
The present invention relates to automobile suspension system, more particularly to a kind of macpherson suspension assembly.
Background technology
Automotive suspension is the important component for ensureing riding comfort, automotive suspension as vehicle body (or vehicle frame) and axletree (or
Wheel) between make the force transferring part that connects, be again the important component for ensureing ride safety of automobile.
Independent suspension is that the wheel of left and right two on an axletree by automobile is individually installed on vehicle body (or vehicle frame)
Under, vehicle bridge uses breakaway-element, and middle one section is fixed on vehicle body (or vehicle frame), mutual not shadow when the sidecar wheel of independent suspension two is hit
Sound, and independent suspension lighter weight, buffering are very strong with damping capacity, and riding comfort is good, every relative to rigid axle suspension
Index is all more excellent.
Present Independent Suspension including macpherson suspension, double cross arm independent suspension and multi-connecting-rod separated suspension etc.,
Wherein, macpherson suspension is with its simple structure, light weight, the advantages of fast response time, is used widely.As shown in figure 1,
Existing macpherson suspension assembly includes shock absorber 1', knuckle 2', lower swing arm 3', lower swing arm ball pin 4' and subframe
5', wherein, one end of knuckle 2' rotates with shock absorber 1' and be connected, and the other end of knuckle 2' passes through lower swing arm ball pin 4' with
One end of swing arm 3' is connected, and the other end of lower swing arm 3' is connected with subframe 5'.
It is well known that the physical dimension of adjustment suspension, the change of camber angle, toe-in etc. when can just change Suspension movement, from
And change the movement locus of tire.Tire is in same movement travel, and swing arm is more long, and transverse movement is smaller, the earth point of tire
Change is small, and camber angle change is small, so that tire wear is just smaller, the stability of vehicle traveling is also better.
And macpherson suspension only has lower swing arm, therefore for the automobile for having used macpherson suspension,
Bottom arm lengths L0The distance between (pivot of lower swing arm ball pin 4' to lower swing arm 3' with the fixing point of subframe 5') is right
The influence of tire wear performance and riding stability is larger.Due to the limitation of installing space, the bottom of macpherson suspension
Arm lengths are shorter, cause the earth point of tire to change greatly, and camber angle changes greatly, causes tire wear big, vehicle run stability
It is poor.
The content of the invention
