The invention provides a lining, and relates to the field of vehicle flexible connecting pieces. The rubber part is located outside the inner pipe, and the inner surface of the rubber part makes contact with the inner pipe; the outer pipe is positioned outside the rubber part; an abutting protrusion is arranged in the middle of the axial direction of the inner pipe and located on the outer surface of the inner pipe, and the abutting protrusion abuts against the inner surface of the rubber part and can apply first abutting force to the rubber part. The outer pipe can apply second abutting force to the end of the rubber part, at least one of the first abutting force and the second abutting force and the axial direction of the rubber part form a preset acute angle, the bush has higher axial rigidity, a system has higher inherent frequency, the possibility that the system generates resonance under external excitation is reduced, and the noise reduction effect is improved. The invention further provides a suspension swing arm of the vehicle, wherein the suspension swing arm is provided with the bushing.

    本发明提供一种衬套,涉及车辆柔性连接件领域,该衬套包括:内管;橡胶件,位于内管的外部,且橡胶件的内表面与内管接触;外管,位于橡胶件的外部;其中,在内管的轴向的中部,内管的外表面具有抵接凸起,抵接凸起与橡胶件的内表面抵接,能够对橡胶件施加第一抵接力;外管能够对橡胶件的端部施加第二抵接力,第一抵接力和第二抵接力中至少一个与橡胶件的轴向成预设的锐角,这种衬套具有更大的轴向刚度,使系统具有更高的固有频率,降低了系统在外部激励下产生共振的可能性,提高了降噪的效果。本发明还提供一种应用了上述衬套的车辆的悬架摆臂。
