我国引进的斯太尔91系列汽车采用的手制动阀原是西德WABCO公司生产的手制动阀,它有两种类型:一种是WABCO公司70年代的手制动阀;另一种是80年代WABCO公司发展的新一代手制动阀。两种手制动阀的功能相同,但结构不同。新型手制动阀在保证灵敏性的前提下尺寸进一步缩小,手柄在工作时运动方向也作了改进,便于司机操作,见图1。由于轮廓尺寸减小,还可以把它布置在一些特殊要求的地方,如仪表板内部。下面介绍这种新型手制动阀。
The hand brake valve used in China’s Steyr 91 series was originally a hand brake valve manufactured by WABCO in West Germany. There are two types of hand brake valves: one is the WABCO hand brake valve from the 1970s; the other Is a new generation of hand brake valves developed by WABCO in the 1980s. Both hand brake valve function the same, but the structure is different. The new hand brake valve to ensure the sensitivity of the premise of further reduce the size, handle the direction of movement has also been improved to facilitate the driver to operate, see Figure 1. Due to the reduced size of the profile, it can also be placed in some special requirements, such as inside the dashboard. The following describes the new hand brake valve.
