Abstract

The invention relates to an upper cover plate for an automatic gearbox hydraulic valve plate. The upper cover plate is provided with an oil circuit connector in a boss shape, the oil circuit connector is provided with a pressure sensor hole used for mounting a pressure sensor, so that the oil circuit pressure of the hydraulic valve plate is collected conveniently when a calibration test is conducted, after the pressure sensor collects corresponding oil circuit pressure information, the information is transmitted to a control system through a wiring harness, oil circuits are orderly, the oil circuit pressure information can be collected easily, and assembling is convenient. The loss of pressure in the oil circuits is reduced, and the pressure of the oil circuits in an outlet of the hydraulic valve plate can be more precisely detected. Moreover, when the calibration test is conducted, the number of tools is reduced, and operation is simple and convenient.

Description

technical field [0001] The invention relates to a multi-speed automatic transmission, in particular to an upper cover plate for a hydraulic valve plate of the automatic transmission, which belongs to the field of mechanical technology. Background technique [0002] In the hydraulic control system of the automatic transmission, the hydraulic valve plate is the transfer station of the entire oil circuit system. Many important oil circuit pressures in the hydraulic valve plate need to be detected. Usually, the detection oil circuit is connected to the casing. The oil circuit is very messy and in the It is difficult to collect the oil circuit pressure information of the hydraulic valve plate during the calibration test. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an upper cover plate for the hydraulic valve plate of an automatic transmission in view of the above deficiencies. Finally, it has the advantages of oi...
