Steel sheet spring capable of damping and limiting

Abstract

The invention provides a steel sheet spring capable of damping and limiting. The steel sheet spring capable of damping and limiting comprises a first sheet spring, a second sheet spring and two damping assemblies, wherein the middle parts of the first sheet spring and the second sheet spring are mutually overlapped and interconnected; a buffering clearance is formed between two ends of the first sheet spring and the second sheet spring; the two damping assemblies are arranged at two ends of the second sheet spring, and each damping assembly comprises a main body which is fixed to the second sheet spring, and a buffering part which is arranged on the surface, facing the first sheet spring, of the main body; the buffering parts are adhered to the main bodies by vulcanization; two opposite ends of the main bodies correspondingly extend to form limiting parts toward the first sheet spring; and the distance between the two limiting parts is not less than the width of the first sheet spring. According to the steel sheet spring capable of damping and limiting, the first sheet spring and the second sheet spring are prevented from rigid contact through the damping assemblies, thus the vibration and noise caused by the sheet springs in moving can be reduced, and meanwhile each sheet spring is limited to transversely move, so that the problem of transverse staggering of each sheet spring can be solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a leaf spring with a damping limit. Background technique [0002] The leaf spring is mainly the elastic element of the automobile suspension system, which also has the functions of a guiding element and a damping element, so that the suspension system has a simple structure and a low cost, which is difficult for other elastic elements. Therefore, since the advent of the automobile , Leaf springs have been in industrial applications, and will still have considerable vitality in the future. [0003] In the prior art, the multi-leaf leaf springs are assembled together by a central bolt or U-shaped bolts through a certain pre-stress. The vibration of the spring, the relative movement between the plates will produce vibration and noise, and at the same time, in the long-term use process, there is easy lateral misalignment between the leaf springs.
