液压控制机构 液压控制机构包括油泵(液压源)、阀体总成(内含液压控制阀及通道选择阀)及液压活塞(作用于离合器及制动器)。1.液压回路(空档) 液压控制机构回路如图16所示。2.油泵 油泵将自动变速器油送到液力变矩器,并且产生油压作用于液压控制机构,并润滑摩擦机件,如行星齿轮及超速传动离合器。油泵的结构如图17所
Hydraulic control mechanism Hydraulic control mechanism includes oil pump (hydraulic source), valve assembly (including hydraulic control valve and channel selection valve) and hydraulic piston (acting on the clutch and brake). 1. Hydraulic circuit (neutral) hydraulic control mechanism circuit shown in Figure 16. 2. Pump The pump delivers automatic transmission fluid to the torque converter and generates hydraulic pressure to the hydraulic control mechanism and lubricates frictional components such as planetary gears and overdrive clutches. The structure of the pump shown in Figure 17
