The invention discloses a passenger vehicle upper suspension assembly, and belongs to the technical field of automobiles. The passenger car upper suspension assembly comprises a first shell, a secondshell and a bushing, wherein the first shell is connected with a vehicle body; the second shell is fixedly connected with the first shell to form an accommodating space, and the second shell is connected with the vehicle body; the bushing is arranged in the accommodating space and comprises an inner core and a rubber sleeve wrapping the outer side of the inner core, first protruding blocks are circumferentially arranged on the peripheries of the upper end and the lower end of the rubber sleeve at intervals, a first trough is formed between every two adjacent first protruding blocks, second protruding blocks lower than the first protruding blocks are circumferentially arranged on the peripheries of the upper end and the lower end of the inner core at intervals, a second trough is formed between every two adjacent second protruding blocks, the first protruding blocks are located in the second troughs, the second protruding blocks are located in the first troughs, and the first protrudingblocks at the two ends of the rubber sleeve abut against the inner wall of the first shell and the inner wall of the second shell respectively. The passenger vehicle upper suspension assembly has theadvantages that vibration transmission can be effectively reduced, and meanwhile, the downward jumping stroke of the suspension can be limited.
本发明公开了一种乘用车上悬置总成,属于汽车技术领域。乘用车上悬置总成包括第一壳体,其与车身连接;第二壳体,其与第一壳体固定连接,以形成容纳空间,第二壳体与车身连接;衬套,其设置在容纳空间内,衬套包括内芯及包裹在内芯外侧的橡胶套,橡胶套的上下两端的周边均周向且间隔设置有第一凸块,相邻两个第一凸块之间形成第一波谷,内芯的上下两端的周边均周向且间隔设置有高度低于第一凸块的第二凸块,相邻两个第二凸块之间形成第二波谷,第一凸块位于第二波谷内,第二凸块位于第一波谷内,且橡胶套两端的第一凸块分别抵接第一壳体的内壁及第二壳体的内壁。其优点在于:能够有效降低振动的传递,同时能够对悬架下跳行程进行限位。
