Description

Technical Field

[0001] The utility model belongs to the technical field of leaf springs, and particularly relates to a leaf spring buffer. Background Art

[0002] A leaf spring is a plate-shaped spring composed of superimposed and combined steel plate springs with no less than one piece; leaf springs are usually used in the suspension of wheeled vehicles and were originally called laminated or carriage springs, sometimes called semi-elliptical springs or trolley springs; in the prior art, when a vehicle is driving on a road surface with gravel, some gravel will fall onto the concave surface at the top of the steel plate spring and accumulate at the bottom of the concave surface. At this time, when the leaf spring buffers the bumps of the vehicle, the upper and lower adjacent groups of steel plate springs squeeze the gravel. In this case, the gravel may damage the steel plate spring, which is not conducive to the use of the leaf spring. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a leaf spring buffer to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:
