The invention provides an auxiliary frame buffering device, an auxiliary frame and an automobile. The auxiliary frame buffering device comprises a liner and a bowl pad. The liner is arranged on the bowl pad. Both the liner and the bowl pad are provided with through holes for inserting connection of the auxiliary frame. The liner comprises an inner sleeve, an outer sleeve and a buffering piece. Theouter sleeve surrounds the outer side of the inner sleeve, and the buffering piece is arranged between the inner sleeve and the outer sleeve. The bowl pad comprises a boss and a supporting part. Thesupporting part is arranged along the edge of the boss. The buffering piece is provided with an extension part. The extension part extends to the position between the outer sleeve and the supporting part from the part between the inner sleeve and the outer sleeve and abuts against the outer sleeve and the supporting part. According to the technical scheme, the buffering piece is provided with theextension part, when the liner and the bowl pad are assembled, the boss abuts against the inner sleeve, the extension part abuts against the supporting part, impact force is weakened through deformation of the buffering piece, accordingly, the function of limiting the stroke during liner and bowl pad stress is achieved, and the taking comfort, smoothness and stability of the automobile are improved to a certain degree.

    本发明提出一种副车架缓冲装置、副车架及汽车,副车架缓冲装置包括衬垫以及碗垫,衬垫设置在碗垫上,衬垫以及碗垫上均设有用于插接副车架的通孔;衬垫包括内套、外套以及缓冲件,外套包绕设置在内套外侧,缓冲件设置在内套与所述外套之间;碗垫包括凸台以及支撑部,支撑部沿凸台的边缘设置,缓冲件上具有延伸部,延伸部从内套与外套之间延伸至外套与支撑部之间,并与外套以及支撑部抵接。本发明技术方案通过在缓冲件上设置延伸部,当衬垫与碗垫装配时,凸台则与内套抵接,延伸部则与支撑部抵接,通过缓冲件的形变削弱冲击力,以起到限制衬垫以及碗垫受力时行程的作用,从而在一定程度上提高车辆的乘坐舒适性、平顺性和稳定性。
