The invention relates to the technical field of automobile parts, in particular to a control arm bushing which comprises an outer sleeve and an inner sleeve arranged in the outer sleeve, a rubber part is connected between the outer sleeve and the inner sleeve in a sleeved mode, and the rubber part is provided with at least one damping hole penetrating in the axial direction. The rubber part is provided with a first contact surface and a second contact surface which are oppositely arranged in the damping hole in the radial direction, the first contact surface is provided with a first convex rib, and the second contact surface is provided with a second convex rib; and the orthographic projection of the first convex rib on the second contact surface is intersected with the second convex rib. The invention further discloses a control arm mounting structure and a vehicle. According to the vibration isolation device, deformation can be generated in the vehicle running process, large impact can be buffered, vibration can be effectively attenuated, the vibration isolation effect is improved, meanwhile, the convex ribs are arranged to change existing surface contact into point contact, and therefore abnormal sound is avoided.
本发明涉及汽车部件技术领域,具体公开了一种控制臂衬套,所述控制臂衬套包括外套管和设于所述外套管内的内套管,所述外套管和内套管之间套接有橡胶件,所述橡胶件设有至少一个沿轴向贯穿的减震孔,所述橡胶件在所述减震孔内形成有沿径向相对布置的第一接触面和第二接触面,所述第一接触面设有第一凸筋,所述第二接触面设有第二凸筋;其中,所述第一凸筋在所述第二接触面上的正投影与所述第二凸筋相交。本发明还公开了一种控制臂安装结构和车辆。本发明能够在车辆行驶过程中产生形变而对大冲击进行缓以及对振动进行有效衰减,提高隔振效果,同时设置凸筋将现有的面接触变为点接触,从而避免异响。
