AI Technical Summary

Technical Problem

Existing vacuum boosters generate noise during operation due to the clearance fit between the valve stem spring seat and the valve stem, which affects the customer's user experience.

Method used

Design a low-noise control valve component for a vacuum booster. Eliminate the valve stem spring seat, redesign the valve stem structure to allow the valve stem return spring to have a clearance fit with the valve stem, and add a boss on the valve stem to reduce noise.

Benefits of technology

This effectively reduces the noise between the valve stem return spring and the valve stem spring seat during the operation of the booster, and lowers the cost of parts.

Abstract

本实用新型属于汽车制动系统技术领域，尤其涉及一种真空助力器的低噪音控制阀部件。空气阀座铆接在阀杆的前端，泡沫滤芯和毛毡滤芯与阀杆滑动连接，阀杆回动簧位于橡胶阀座内，橡胶阀部件与橡胶阀座固定连接，橡胶阀簧位于橡胶阀座上，阀杆回动簧与阀杆间隙配合、且后端位于阀杆的凸台上。优点是结构新颖，通过取消阀杆簧座，在尽量减少新设计零件的情况下，重新设计阀杆，既减少了助力器工作过程中阀杆回动簧与阀杆簧座之间产生的噪音，又可以降低零件成本。
