Description

Technical Field

[0001] This application belongs to the technical field of buffer devices, and particularly relates to a buffer member, a suspension assembly and a vehicle. Background Art

[0002] Commercial vehicles usually have a large load capacity. Especially in some sites with harsh operating environments, such as mines, construction sites, etc., the stress conditions of the commercial vehicle chassis are more complex. In addition to bearing a large static load, the chassis also bears a large dynamic load. These dynamic loads are usually borne by rubber buffer bodies installed between the leaf spring and the frame or between the axle and the frame. Due to frequent impacts from dynamic loads, the rubber buffer bodies are prone to damage and need to be replaced regularly.

[0003] In the buffer structures in related technologies, when damaged, they need to be replaced as a whole. Moreover, for different vehicle models, a new buffer structure needs to be developed, resulting in high maintenance costs and poor versatility. Summary of the Utility Model

The first ends of the side plates are detachably connected to the connecting portion, the second ends of the side plates are fixedly connected to the bottom plate, and the bottom plate is configured to be connected to the frame.

[0008] In some embodiments, the bracket further includes a top plate, and the top plate is fixedly connected to the first ends of the side plates and abuts against the connecting portion.

[0009] In some embodiments, the bracket further includes a reinforcing plate. A reinforcing plate is arranged between every two adjacent side plates, and the reinforcing plate is fixedly connected to the bottom plate and the adjacent side plates.

[0010] In some embodiments, multiple reinforcing plates are arranged at intervals along a second direction, and the first direction intersects with the second direction.

[0011] In some embodiments, the connecting portion includes a connecting plate and two first flanges. The two first flanges are arranged on both sides of the connecting plate at intervals along the first direction. A clamping groove is formed by enclosing the connecting plate and each first flange, and the clamping groove is clamped to the bracket. Each first flange is detachably connected to the bracket.

[0012] In some embodiments, the bracket further includes a connecting member and a first fastener. The connecting member is provided with a threaded hole, the first folded edge is provided with a first connecting hole, and the side plate is provided with a second connecting hole. The first connecting hole, the second connecting hole and the threaded hole communicate with each other. The first fastener passes through the first connecting hole and the second connecting hole and is screwed to the connecting member.

[0013] In some embodiments, the first connecting hole is an oblong hole.

[0014] In some embodiments, the bracket further includes a second folded edge, and the second folded edge is bent and connected to the bottom plate.

[0015] The embodiment of the present application further provides a suspension assembly, including:

[0016] The buffer member as described above;
