定轴式动力换档变速箱在工程机械上应用广泛,为了提高其换档的可靠性和平稳性,对快速排油阀的作用不能忽视。原天津汽车修配公司生产的JZ425装载机,在换档时冲击较大,甚至有时挂不上档,问题就出在快速排油阀上。现对快速排油阀探讨如下。一、快速排油阀的工作原理快速排油阀的基本结构及其工作原理如图1所示。由图可见,快速排油阀的基本构造是,
Fixed-axis power shift transmission gearbox widely used in construction machinery, in order to improve the reliability and stability of its shift, the role of fast oil discharge valve can not be ignored. The original JZ425 loader produced by Tianjin Auto Repair Co., Ltd. has had a big impact when shifting gears, and sometimes it can not even be hung. The problem lies in the fast oil drain valve. Now on the fast drain valve discussed below. First, the rapid drain valve working principle Fast drain valve basic structure and its working principle shown in Figure 1. Can be seen from the figure, the basic structure of the rapid drain valve,
