The invention discloses a vacuum booster assembly, which relates to the field of automobile parts and comprises a control valve, a servo piston, a dust cover, a rear shell assembly, a front shell, a large servo diaphragm, a small servo diaphragm, an output push rod assembly, a stay bolt and a control valve rod. The front shell, the rear shell and the separation frame of the vacuum booster are connected in series through the stay bolt, the opposite acting force of the brake master cylinder is borne by the stay bolt during working, and therefore elastic deformation and permanent deformation are reduced. Meanwhile, the material thickness of the front shell is 0.8 mm, the material thickness of the rear shell is 1.0 mm, the weight of the vacuum booster is about 3.0 Kg, and the weight of the vacuum booster is reduced by about 32% compared with that of a vacuum booster with the shell material thickness being 1.8 mm.
本发明公开了一种真空助力器总成,涉及汽车零部件领域,包括控制阀、伺服活塞、防尘罩、后壳总成、前壳、大伺服膜片、小伺服膜片、输出推杆总成、拉杆螺栓和控制阀杆。本发明用拉杆螺栓将真空助力器的前、后壳体及隔架串联在一起,工作时制动主缸的反向作用力由拉杆螺栓来承受,以此减少弹性变形量及永久变形。同时,本发明的前壳体材料厚度为0.8mm,后壳体的材料厚度为1.0mm,真空助力器的重量约为3.0Kg,较壳体材料1.8mm厚度的真空助力器减重约32%。
