Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an auxiliary frame buffer device, an auxiliary frame and an automobile. Background technique [0002] The pad is used to attenuate the impact force and isolate the impact force to the body when the sub-frame is impacted by the ground, thereby improving the ride comfort, ride comfort and stability of the vehicle. However, in the current subframe, when the gasket is installed, the gasket is directly fastened to the subframe through the hexagonal flange nut, or the nut is fastened with the gasket, and the gasket is solid. , the deformation stiffness of the pad is linear, and its deformation stroke cannot be limited, so the stiffness change cannot be controlled, resulting in poor ride comfort, ride comfort and stability of the vehicle. Contents of the invention [0003] The main purpose of the present invention is to provide a sub-frame buffer device, a sub-frame ...
