SB11S型推耙机采用液力换挡变速器,该变速器由液力变矩器和换挡变速器组成,若该推耙机发生不能行走故障,其排查和维修比较复杂,为了排查故障有时需要拆装驾驶室。本文讲述该推耙机不能行走故障类型、排查方法和排查实例。1.故障类型SB11S型推耙机不能行走故障,按液力换挡变速器油温高低,可分为冷车不能行走和热车不能行走2种类型。冷车不能行走是指启动发动机,待转速升至中速时挂挡,推耙机不能立即行走。热车不能行走是指推耙机在作业过程中,随着液力换挡变速器油温不
SB11S push rake hydraulic transmission gearbox, the transmission by the torque converter and gear shift transmission composition, if the push rake can not walk fault, the troubleshooting and maintenance is more complicated, in order to troubleshoot the need to dismantle Cab. This article describes the push rake can not walk the type of failure, troubleshooting methods and troubleshooting examples. 1. Type of failure SB11S push rake can not walk fault, according to hydraulic transmission gearbox oil level, can be divided into cold car can not walk and hot car can not walk 2 types. Cold car can not walk is to start the engine until the speed rose to medium speed when hanging, push rake can not immediately walk. The hot car can not walk is pushing rake machine in the operation process, with hydraulic shift transmission oil temperature is not
