一台已使用了3年的ZL30C型装载机,每当发动机刚启动时,变矩器齿轮室透气孔处就向外窜油;随着使用时间的延长,变速器壳体中油位不断增高。 该机系变速器、变矩器分体式结构,其液压系统由工作系统、操纵系统和转向系统3个独立部分构成。发动机的动力通过泵轮壳上的主动齿轮驱动安装在变矩器壳体上的3个齿轮泵工作。 分析认为,变矩器透气孔处窜油的原因主要有三方面:一是出口压力阀阀芯卡滞,
A ZL30C loader, which has been in use for three years, ramps oil out of the air vents of the gearbox chamber every time the engine is started; as the service life increases, the oil level in the transmission casing increases. The machine system transmission, torque converter split structure, the hydraulic system by the working system, steering system and steering system composed of three separate parts. Engine power through the impeller on the pump housing drive gearbox mounted on the gear pump work 3. Analysis, the torque converter breathable hole at the main reason there are three aspects: First, the outlet pressure valve spool stagnation,
