The invention relates to an adjustable ball head type vacuum booster assembly, which belongs to vacuum boosters in the technical field of automobile brake systems. On the structural basis of an existing vacuum booster, the end, located outside a dust cover, of a valve rod is provided with an external thread, an adapter ball head with an internal thread at one end is in threaded connection with theexternal thread of the valve rod, and a hexagon thin nut is in threaded connection with the external thread of the valve rod and locks the adapter ball head. The vacuum booster assembly has the advantages that the structure is novel, an original ball head type valve rod is split into the valve rod with the thread and the adapter ball head with the thread, the height of the ball head of the vacuumbooster assembly can be adjusted under the condition that only the valve rod is changed, and the performance of the vacuum booster assembly is not affected; compared with a conventional ball head type vacuum booster assembly, the adjustable ball head type vacuum booster assembly has the function of adjusting the distance between the ball head and the end face of the rear shell; and the vacuum booster can be applied to various types of ball head type vacuum booster assemblies, and has good cost performance.
本发明涉及一种可调球头式真空助力器总成,属于汽车制动系统技术领域的真空助力器。在现有真空助力器的结构基础上,阀杆位于防尘罩外部的一端有外螺纹,一端带有内螺纹的转接球头与该阀杆的外螺纹螺纹连接,六角薄螺母与阀杆的外螺纹螺纹连接、并将转接球头锁紧。优点是结构新颖,将原有球头式阀杆拆分成带有螺纹的阀杆和带有螺纹的转接球头两部分:在只改变阀杆的情况下,便可实现调节真空助力器总成球头高度,不影响真空助力器总成性能;与常规的球头式真空助力器总成相比,此可调节球头式真空助力器总成具有调节球头到后壳体端面距离的功能;可应用于各种类型球头式真空助力器总成上,具有良好的性价比。
