自动变速箱的深入剖析分析

发布日期: 2021-05-11 来源: / 点击:

在自动波箱修理行业,控制翻修率总是人们关心的因素之一,因为它直接关系到企业的利润、企业的品牌以及业务的发展前景。然而这又是难解决的问题,如果限于表面的修理而不找出变速箱内部的故障根源,翻修率是很难控制的,尤其是当变速箱进入正常维修期,内部的故障开始出现的时候。

In the automatic wave box repair industry, controlling the renovation rate is always one of the factors that people care about, because it is directly related to the profit of the enterprise, the brand of the company and the development prospect of the business. However, this is a difficult problem to solve. If the repair is limited to the surface and the root cause of the internal fault of the transmission is not found, the repair rate is very difficult to control, especially when the transmission enters the normal maintenance period and the internal fault begins to appear.
要做到正确的故障分析和成功的变速箱翻新,理解变速箱内的一个重要的油路循环是尤其关键的:油泵-主调压阀-变扭器-散热器润滑回路。从图1可以看到,油泵/调压阀和变て鹘?润滑油路实际上处于串联关系,按先后次序联系在一起的。
In order to achieve correct fault analysis and successful gearbox renovation, it is particularly critical to understand an important oil circuit cycle in the gearbox: oil pump - main pressure regulating valve - torque converter - radiator lubrication circuit. As can be seen from Figure 1, the oil pump / pressure regulating valve and the transformer are connected? In fact, the lubricating oil circuit is in series and connected in sequence.
这其中的任一部分出现变化,都会直接影响到其它的部分。这里大家将要深入探讨这些系统是如何相互联系在一起的,以及如何用流量计(SonnaFlow®)来帮助监测它们的运行,同时也更容易理解索奈克斯的阀体零件是如何修复变速箱内的液力回路使其正常工作的。
If any part of this changes, it will directly affect other parts. Here we are going to explore how these systems are interconnected and how to use the Sonna flow meter ®) To help monitor their operation, and at the same time, it's easier to understand how Sonex's valve body parts repair the hydraulic circuit in the gearbox to make it work properly.
调压阀(以下称“PR阀”)是这个油路循环中的核心部件。液力泵可以产生非常大的油压,PR阀能将油压限 制或调节在变速箱中通常的50-250psi(磅/平方英寸,美制压力单位)的范围内。受调制的主油路压力的变化范围是由分别位于PR阀两端的弹簧和油路压力共同决定的。
Pressure regulating valve (hereinafter referred to as "PR valve") is the core component of the oil circuit cycle. The hydraulic pump can produce very large oil pressure, and the PR valve can limit or regulate the oil pressure within the range of 50-250psi (pounds per square inch, American pressure unit) in the transmission. The variation range of the modulated main oil pressure is determined by the spring and oil pressure at both ends of the PR valve.
在通常情况下,PR弹簧和增压阀推动PR阀向一个方向运动,而阀另一端的平衡压力阻止或方向推动PR阀,从而使PR阀处于一个平衡调节位置。在启动时,当PR阀平衡端的油压达到后,PR阀会克服弹簧(以及增压阀)的压力,朝它的平衡调节位置移动。一旦油泵产生了足够大的油路压力将PR阀推入它的平衡调节位置,PR阀会将多余的油泵容量导入泄油孔,或导回油泵的吸入端
Under normal circumstances, the PR spring and the booster valve push the PR valve to move in one direction, while the balance pressure at the other end of the valve prevents or pushes the PR valve in the other direction, so that the PR valve is in a balance adjustment position. During start-up, when the oil pressure at the balance end of PR valve reaches, PR valve will overcome the pressure of spring (and booster valve) and move towards its balance adjustment position. Once the oil pump generates enough oil pressure to push the PR valve into its balance adjustment position, the PR valve will lead the excess oil pump capacity into the drain hole or back to the suction end of the oil pump
