The invention discloses a bushing and a vehicle control arm assembly. The bushing comprises an outer pipe, an inner pipe and a connecting part. The outer pipe and the inner pipe are coaxially arranged, and the inner circumferential surface of one end of the outer pipe is connected with the inner circumferential surface of the corresponding end of the inner pipe through the connecting part. A protruding part is arranged on the outer end face of one end of the outer pipe and protrudes outwards in the axial direction of the outer pipe. Due to the arrangement of the structure, the auxiliary framecan be in contact with the control arm under any condition, and then abnormal sounds generated by friction between the auxiliary frame and the control arm can be avoided. Due to the arrangement of theprotruding part, stress between the bushing and the auxiliary frame is more uniform, the bushing can be protected, the situation that the bushing is affected when the control arm and the auxiliary frame get away from each other or get close to each other can be avoided, the service life of the bushing is prolonged, and then the reliability of the vehicle control arm assembly can be improved.
本发明公开一种衬套及车辆控制臂总成,该衬套包括外管、内管以及连接部。其中,外管与内管呈同轴布置,并且外管一端的内周表面与内管相应一端的内周表面通过连接部连接在一起。外管的一端的外端面设置有突出部,且突出部沿外管的轴向向外突出。这种结构的设置可使得副车架与控制臂在任何情况下均接触,进而可避免副车架与控制臂摩擦产生异响。并且突出部的设置还使得衬套与副车架之间的受力更加均匀,以及可对衬套起到保护作用,可以避免控制臂和副车架在互相远离或靠近时对衬套造成影响,以提高衬套的使用寿命,进而可以提高车辆控制臂总成的可靠性。
