The invention relates to a booster assembly capable of adjusting a jump increasing value without disassembling the assembly, and belongs to a vacuum booster assembly in the technical field of automobile brake systems. The diameter of the retainer is smaller than that of a main cylinder hole of the front shell, the retainer is in interference fit with the valve body, a limiting return spring structure is additionally arranged on the valve body, axial limiting of the retainer is changed, and the return spring is limited by the valve body. The vacuum booster assembly has the advantages that the structure is novel, the jump increasing value can be adjusted without disassembling the assembly under the condition that only the valve body and the retainer are changed, and the performance of the vacuum booster assembly is not influenced. Compared with a conventional vacuum booster assembly, the booster assembly capable of adjusting the jump increasing value without disassembling the assembly has the functions of being simple in adjustment of the jump increasing value and reducing the rejection rate of products, has good cost performance, and has the advantages of being simple in product structure, complete in function and capable of adjusting the jump increasing value without disassembling the vacuum booster assembly. The vacuum booster is suitable for different vacuum booster assemblies.
本发明涉及一种无需拆解总成可调整增跳值的助力器总成,属于汽车制动系统技术领域的真空助力器总成。护圈直径小于前壳体主缸孔直径,护圈与阀体过盈配合,阀体上增加限位回位簧的结构,更改护圈的轴向限位,回位簧由阀体进行限位。优点是结构新颖,在只改变阀体、护圈的情况下,便可实现无需拆解总成调整增跳值,不影响真空助力器总成性能。与常规的真空助力器总成相比,此无需拆解总成可调整增跳值的助力器总成具有增跳值调整简单,减少产品报废率的功能同时具有良好的性价比,具有产品结构简洁、功能齐全,具有无需拆解真空助力器总成便可调整增跳值功能,适用于不同真空助力器总成上。
