Even, lower end is connected with vertical arms；The upper end of damper is connected with vehicle body, and lower end is connected by stent with vertical arms；
Disturbing rod is arranged in the upside in brake axle center, and one end and the vertical arms of disturbing rod are assembled, the other end and vehicle frame or secondary vehicle
Frame is assembled；Limited block is assemblied on vehicle body.
The present invention has the following advantages that compared with prior art：
1st, a kind of vertical arms of the invention disturbance rod-type independent suspension structure, by the glue of the trailing arm of traditional single trailling arm type suspension
The axis arrangement of set is angled, and increases lateral disturbing rod on trailing arm top, provides multidirectional control force for suspension, disturbs
Lever can resist the tendency of the wheel top introversion caused by the moment of flexure of tire ground force, and effectively be corrected in wheel hop
The excessive introversion of wheel or the harmful trend of flare；
2nd, the characteristics of present invention has simple in structure, and unsprung mass is small is conducive to improve vehicle ride comfort；
3rd, the present invention effectively combines the high resiliency and viscoelasticity characteristic of rubber bushing, and rubber bushing has low temperature resistant, resistance to
The characteristic of fatigue, shock stiffness are more than dynamic stiffness, and dynamic stiffness is more than Static stiffness, effectively reduces blastic deformation and dynamic deformation,
The structure takes full advantage of the vibration damping feature of hinge joint rubber, can reach higher ride comfort by orienting matching optimization and multiply
Sit comfort；
4th, vertical arms of the present invention include the first rubber bushing, the second rubber bushing and trigonometric expression trailing arm main body, the first rubber
Glue bushing stiffness is connected to the end of trigonometric expression trailing arm main body, and is hinged with vehicle body；Second rubber bushing is rigidly attached to triangle
The end of formula trailing arm main body, and be hinged with vehicle body, specific aim can be done according to vehicle concrete condition by connecting angle and degree of freedom limitation
Adjustment, the hinge joint and disturbing rod can do orientation adjustment for vehicle, and development cost are low, be adjusted by the position of hinge
Active accommodation wheel alignment when can enable Suspension movement can improve tire earth-grasping force to greatest extent, improve handling
Energy.
