Abstract
The utility model relates to an upper cover plate for an automatic speed changer hydraulic valve plate. An oil way connector in a boss shape is arranged on the upper cover plate. A pressure sensor hole for mounting of a pressure sensor is formed in the oil way connector. During a calibration test, oil way pressure of the hydraulic valve plate can be collected conveniently. The pressure sensor collects corresponding oil way pressure information and then transmits the oil way pressure information to a control system through a wire harness. Oil way condition and oil way pressure information can be collected easily, assembling is convenient, pressure loss in an oil way is reduced, the pressure of the oil way at a hydraulic valve plate outlet can be detected accurately, during the calibration test, the number of tools is reduced, and operation is easy.
