二、液压控制系统1.F4A4液压控制系统概述(1)系统使用一个齿轮式油泵建立液压。(2)有两个重要的油压调节阀:一是系统压力调节阀,用于调节变速器的工作压力;二是变矩器压力调节阀,用于稳定到变矩器的油压,在换挡杆不同的位置和不同的挡位时,有不同的系统油压,这由机械式调压阀实现,没有使用压力控制电磁阀。
Second, the hydraulic control system 1.F4A4 hydraulic control system Overview (1) The system uses a gear pump to establish hydraulic. (2) There are two important oil pressure regulating valves: one is the system pressure regulating valve, which is used to adjust the working pressure of the transmission; the other is the torque converter pressure regulating valve, which is used to stabilize the oil pressure of the torque converter, There are different system hydraulic pressures for different positions and different gear positions of the baffles. This is achieved by a mechanical pressure regulator without the use of a pressure control solenoid valve.
