1.分类及工作原理(1)分类电液换挡变速器通过开关挡位电磁阀来切换挡位,然后通过换挡操纵阀实现挡位离合器摩擦片的接合与分离。换挡操纵阀具有调压功能,可使挡位离合器工作油压平缓上升,从而提高换挡品质。电液换挡系统有全自动和半自动之分。全自动电液换挡系统挡位控制器可根据油门开度、车速和挡位选择器位置等传感器信号,由中央处理器(CPU)根据各传感器信号,按照设定的换挡规律计算出适应当前工况的最佳挡位,并自动控制换挡操纵阀进行换挡。
1. Classification and working principle (1) Category Electro-hydraulic shift transmission through the shift gear solenoid valve to switch the gear, and then through the shift valve to achieve gear clutch friction plate engagement and separation. Shift control valve has a pressure regulating function, allowing the gear clutch work oil pressure rise, thereby improving the quality of the shift. Electro-hydraulic shift system with automatic and semi-automatic points. Automatic electro-hydraulic shift system gear controller according to the throttle opening, speed and gear selector position and other sensor signals from the central processing unit (CPU) according to the sensor signal, according to set the shift rule to calculate the adaptation The current conditions of the best gear, and automatic control shift shift valve for gear.
