我单位共有4台卡特14M型平地机,主要用于矿区内道路修复或平整施工场地。该型平地机采用电子控制(ECPC系统控制)液压换挡平行轴式变速器,可以实现平稳换挡和换向。本文介绍卡特14M平地机变速器控制原理,分析其出现高温故障的原因。1.变速器控制原理(1)油路流向该型平地机变速器液压换挡控制系统如图1所示。发动机将动力传输至变速器,变速器内的泵轴带动齿轮泵10转动,齿轮泵10为充油
My unit has a total of 4 Carter 14M grader, mainly used for road construction in the mining area or flat construction site. This type grader adopts electronic control (ECPC system control) hydraulic shift parallel shaft type transmission, which can achieve smooth shift and commutation. This paper introduces the control principle of Carter 14M grader transmission and analyzes the cause of high temperature failure. 1. Transmission control principle (1) the flow of oil This type of grader transmission hydraulic shift control system shown in Figure 1. The engine will power transmission to the transmission, the gear pump shaft drive gear pump 10 rotation, gear pump 10 is filled with oil
