Abstract

An EPS rack clearance buffering stop block assembly comprises a pressing block cylinder and a rubber ring. An inward-concave arc rack contact hook face is arranged at the bottom of the pressing blockcylinder, and a concave annular groove is formed in the top of the pressing block cylinder. A protruding rubber ring positioning table is arranged in the middle of the annular groove. The rubber ringis arranged in the annular groove and is limited in the pressing block cylinder through the rubber ring positioning table. The pressing block cylinder is manufactured in the manner that nylon and glass fiber are main materials and subjected to injection molding, and a teflon coating is used for processing plastics; and the rack contact hook face is provided with at least five parallel U-shaped grooves. The EPS rack clearance buffering stop block assembly solves the problems that an EPS stop block assembly on the market is prone to abrasion, abnormal sounds are obvious, the manufacturing manufacturability is poor, and cost is high.

Description

technical field [0001] The invention relates to an EPS assembly, in particular to an EPS rack gap buffer block assembly. Background technique [0002] With the development and progress of the current society, automobiles have become one of the most important means of transportation. At the same time, people's performance requirements for automobiles are also increasing, especially EPS with good performance. The traditional hydraulic steering machine has defects such as oil leakage, abnormal noise, high energy consumption, and poor economy. However, the current EPS gear uses a rack to mesh, and the back of the rack uses a metal stopper to limit the gap between the rack and pinion to make the rack rub left and right. At the same time, the back of the stopper uses spring compression to adjust the gap. This design leads to the problem of large meshing gap between the rack and pinion and prominent abnormal noise; moreover, the friction coefficient between the metal stopper and th...
