Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a buffer for running gear as shown in fig. 1-3, including mounting bracket 1, base 2 is inlayed to one side of mounting bracket 1, and the outside cover of base 2 is equipped with sleeve 11, one end of sleeve 11 and one side fixed connection of mounting bracket 1, and the one end of base 2 is equipped with buffering subassembly, and the fixed baffle 8 that is equipped with of one end of buffering subassembly, one side of baffle 8 and sleeve 11's other end inner wall fixed connection, buffering subassembly's outside cover is equipped with spring 3, and spring 3's one end and base 2 fixed surface are connected, spring 3's the other end and baffle 8 fixed connection.

Buffering subassembly includes rubber cushion 7, the one end of

rubber cushion

7 and 8 opposite side fixed connection of baffle, the fixed guide arm 6 that is equipped with a plurality of equidistance distributions of the other end of rubber cushion 7, set up guide slot 4 relative with guide arm 6 position on the base 2, guide arm 6 is with 4 slip joints of guide slot relative in position, the one end of guide arm 6 is equipped with blotter 5, the one end of blotter 5 and the cell wall fixed connection of guide slot 4, it compresses in the horizontal direction to utilize buffering subassembly to make spring 3 be when being extrudeed, prevent that spring 3 is in the compression of bending, and sleeve 11 plays the guard action to spring 3 and buffering subassembly.

Spring 3's surface swing joint has a plurality of equidistance ball 10 that distribute, and ball 10 movable mounting utilizes ball 10 to guarantee spring 3 when the compression, and sleeve 11 makes synchronous compression between sleeve 11 and the spring 3 along with spring 3's compression synchronous compression, prevents that sleeve 11 from breaking at the outside past expansion of spring 3, makes sleeve 11 along with spring 3 synchronous compression and resilience, increases sleeve 11's resilience.
