Limit bushing for limiting ultimate displacement of engine

Abstract

The invention relates to a limit bushing for limiting ultimate displacement of an engine, and belongs to the technical field of automobile parts. The limit bushing comprises a bushing body, wherein a limit support in a [ shape is fixed on the inner side of the bushing body, a suspending soft pad is arranged in the bushing body, and a limit stop is arranged in the suspending soft pad and is matched with the limit support. According to the technical scheme, compared with a vulcanized rubber block used in the prior art, the limit bushing has the advantages that the limit support is added to the inside of the bushing body, the hardness is higher, the structural stability is better, a suspension support of the engine is rapidly limited, and the engine is prevented from interfering with peripheral parts, therefore, beneficial technical effect and remarkable practical value are achieved.

Description

technical field [0001] The invention relates to a limit sleeve used for limiting the limit displacement of an engine, which belongs to the technical field of auto parts. Background technique [0002] In the current field, in order to constrain and fix the automobile engine mount, the engine mount is generally constrained by a limit structure to prevent the vibration of the engine from causing the displacement of parts. The conventional limit structure includes a limit sleeve as shown in 1. Tube 1, the limit sleeve used in automobiles is generally designed to limit the limit displacement of the engine by vulcanizing the rubber block inside the limit sleeve 1. The hardness of the rubber itself is low, which is difficult to meet the limit design requirements, so the engine limit The deformation is large, and it is easy to interfere with the surrounding boundaries, resulting in abnormal noise of the whole vehicle, which poses a safety hazard. Contents of the invention [0003...
