Problems solved by technology

The wear of the slide valve of the valve body often causes the transmission shifting impact or even slips and burns the automatic transmission. However, due to the complex and precise structure of the valve body, the performance detection of the valve body has become a blind spot and difficulty in the maintenance of automatic transmissions.
[0003] Domestic patent CN201043933Y discloses a detection device for automatic transmission of automobiles. The device is fixed on it by a frame, lifting and loading components. The detection of the automatic transmission of the vehicle by the device ultimately needs to be connected to the test board of the transmission detection with the device, which cannot truly achieve the purpose of efficient and accurate detection of the automatic transmission

Abstract

The invention relates to the field of machines for detecting valve bodies during automobile maintenance, in particular to a machine for detecting the valve body of the automobile automatic speed changer. The machine comprises a case, a motor, an oil pump, an oil tank, a heater, a pressure regulation system, a valve body adaptation board, the valve body and a servo motor, and is characterized in that: the motor is arranged at the bottom of the case and connected with the oil pump; the oil tank is arranged in the middle of the case; the heater is arranged in the oil tank; an oil return disk is arranged at the bottom of the oil tank and connected with the inlet end of the oil pump through a pipeline; the outlet end of the oil pump is connected with the pressure regulation system through a pipeline; the top of the oil tank is connected with the valve body through the valve body adaptation board; the valve body is connected with the servo motor through a line; and the pressure regulation system is connected with the valve body through a pipeline. The machine can be used for comprehensively, effectively and accurately detecting electrical performance and mechanical performance of the valve bodies of various types of automatic speed changers.

Description

[technical field] [0001] The invention relates to the field of an automobile maintenance inspection valve body inspection machine, in particular to an automobile automatic transmission valve body inspection machine and a inspection method. [Background technique] [0002] The current shift control of automatic transmissions directly controls the work of actuators such as clutches or brakes through valve bodies. The wear of the slide valve of the valve body often causes the transmission shift shock or even slips and burns the automatic transmission. However, due to the complex and precise structure of the valve body, the performance detection of the valve body has become a blind spot and difficulty in the maintenance of the automatic transmission. [0003] Domestic patent CN201043933Y discloses an automatic transmission detection device for automobiles. The device is fixed on it by a frame, lifting and loading components. The device still needs to be connected with the test b...
