The utility model relates to a 11 inch vacuum booster assembly with a reinforcing structure of a power assisted disk, which belongs to the field of automobile braking. The riveting parts of the front shell and the rear shell are connected through riveting points, the cushion plate is fixed by the screw and the riveting part of the rear shell, and the seal ring and the rear shell riveting part are riveted to form a sealed shell. The sealing ring is in interference with the valve body. The support disc and the valve body are filled with the diaphragm, and the control valve parts and the valve body are connected through the lock card. Matching, pressing block, spacer pad, feedback disc, retainer and main cylinder push rod are assembled inside the valve body. The advantage of the utility model is that the structure is novel, the positioning structure of the contact position of the support disc and the valve body is improved, the bending is increased, the size of the support disc and the valve body is matched, thus the stress of the stress concentration point is reduced, the reliability of the product is improved, and the structure of the traditional structure support disc and the valve body is well solved on the large size product. It has advantages of good location, simple assembly, small space occupation and easy processing.
【技术实现步骤摘要】
一种具有助力盘加强结构的11英寸真空助力器总成
本技术属于及汽车制动领域,尤其是指一种真空助力器总成。
技术介绍
现有用于汽车制动的常规真空助力器总成由:前壳体、后壳体、后壳体螺栓、导向杆、密封圈部件、控制阀部件、锁片、防尘罩、调整叉、压块、反馈盘、主缸推杆、护圈、回位弹簧、支撑垫、密封圈、阀体、膜片、助力盘等主要零部件组成。常规真空助力器总成工作中,由制动踏板输入力,带动控制阀部件与阀体配合,通过膜片将真空助力器总成分为前后两腔,前腔为真空腔,后腔接通大气,受大气压力作用产生助力效果。但随着汽车工业发展,中大型乘用车逐渐走入日常生活,对制动系统制动效果要求逐渐提升,大尺寸真空助力器随之出现,然而大尺寸真空助力器的助力盘在工作时受力强度大幅提升,导致助力盘与阀体接触位置应力集中,在行驶的汽车频繁制动时,可能导致助力盘由应力集中位置出现开裂破损等异常现象,造成制动效能降低,当汽车行驶在拥挤的都市及高速公路上极易发生追尾、撞车等交通事故,严重危及生命财产的安全。
