Novel limiting block structure

Abstract

The invention provides a novel limiting block structure which comprises a rubber main spring and an inner metal part. The rubber main spring is mounted in the inner metal part. The interior of the rubber main spring is of a hollow structure. A boss is arranged on the inner metal part and can limit overall bounce displacement of a frame. The novel limiting block structure has the beneficial effectsthat overall bounce displacement of the frame can be limited by a product adopting the structure; the problem of accumulation of outside liquid is solved by the product adopting the structure; by means of the limiting block structure, bolt and product integration is achieved, and production efficiency can be improved easily; and after a novel limiting block is adopted for loading, the good capacity of absorbing vibration is achieved, and overall vehicle smoothness is greatly improved.

Description

technical field [0001] The invention relates to the field of automobile chassis accessories, in particular to a novel limiting block structure. Background technique [0002] Current state of the art: [0003] The limit block is a key damping part of the chassis system. It is a rubber part. Its main function is to absorb the vibration generated by the car when driving on uneven roads. At the same time, it can limit the distance between the axle and the frame under severe working conditions. The maximum displacement between them is crucial to the NVH of the vehicle; this part is generally used to assemble on the frame, and it has been widely used in some commercial models. [0004] Disadvantages / deficiencies of existing technologies: [0005] 1. The structural design conflict between the soft limit and the hard limit of the product structure cannot guarantee the stiffness performance and limit the jumping displacement of the product at the same time, resulting in a mismatch ...

AI Technical Summary

Problems solved by technology

[0005] 1. The structural design conflict between the soft limit and the hard limit of the product structure cannot guarantee the stiffness performance and limit the jumping displacement of the product at the same time, resulting in a mismatch between the stiffness of the limit block and the vehicle system, and poor vibration absorption effect;

[0006] 2. The durability of the product is poor. Under the harsh working conditions of the car, the product is subject to excessive impact and is prone to failure
