The invention relates to an 8-inch vacuum booster with a non-uniform air passage valve body, and belongs to a vacuum booster assembly in the technical field of automobile brake systems. The front shell is riveted with the rear shell, the rear shell is in interference fit with the valve body through a rubber part and a rear shell air seal, the boosting disc is in riveting fit with the valve body, the control valve part is assembled with the valve body through a locking plate in a clamping mode, the feedback disc, the main cylinder push rod and the retainer are assembled on the valve body, and one end of the return spring is assembled with the retainer, a dustproof cover is assembled on an air seal of the rear shell; four ventilation air channels are formed in the end face of the valve body,and the four ventilation air channels are non-uniformly distributed and form a certain angle so as to avoid riveting points when the assistance disc and the valve body are riveted. The utility modelhas the advantages that the structure is novel, the non-uniformly distributed ventilation air passages are used for replacing the original uniformly distributed ventilation air passages, so that the riveting points avoid the ventilation air passages, the ventilation effect is achieved, the air passages are prevented from being blocked by the riveting points, the safety problem is avoided, the safety is high, and the error-tolerant rate is high.

    本发明涉及一种具有非均布气道阀体的8英寸真空助力器,属于汽车制动系统技术领域的真空助力器总成。前壳体与后壳体铆接,后壳体与阀体通过橡胶件后壳气封过盈配合,助力盘与阀体铆接配合,控制阀部件与阀体通过锁片卡接装配,反馈盘、主缸推杆、护圈装配在阀体上,回位簧一端与护圈装配,另一端与前壳体装配,防尘罩装配在后壳气封上,该阀体在端面有4个通气气道,该4个通气气道非均布,均成一定角度,以躲避助力盘与阀体铆接时的铆点。优点是结构新颖,用非均布的通气气道代替原来均布的通气气道,进而使铆点避让通气气道,达到通气效果,避免铆点堵塞气道,进而避免发生安全问题,安全性高,容错率高。
