Embodiment Construction
[0018] figure 1 A schematic structural view of a valve body assembly of a dual-clutch gearbox in the prior art is shown. Such as figure 1 As shown, the valve body assembly of the dual-clutch transmission includes the actuator valve body 1 and the solenoid valve body 2, and the valve body partition 3 is fixedly installed between the actuator valve body 1 and the solenoid valve body 2 to provide a seal And the role of dividing the oil circuit. When performing a hydraulic test, drill holes at the corresponding positions on the actuator valve body 1 and the solenoid valve body 2, and install a pressure sensor (not shown in the figure) in the hole, and the oil pressure value measured by the pressure sensor To judge whether the corresponding pressure test point in the dual-clutch gearbox valve body is faulty. However, due to the generally complex structure of the valve body of the dual-clutch gearbox, and various interface components are installed on the valve body, many test ele...

The invention discloses a hydraulic testing device of a double-clutch transmission valve body, which is suitable for being arranged between an electromagnetic valve body and an actuator valve body. The hydraulic testing device comprises a sensor oil way plate, a first separation plate and a second separation plate, wherein the sensor oil way plate is provided with a pressure sensor suitable for measuring an oil pressure; a first surface of the sensor oil way plate is fixedly mounted with the actuator valve body through the first separation plate; and a second surface, opposite to the first surface, on the sensor oil way plate is fixedly mounted with the electromagnetic valve body through the second separation plate. As the sensor oil way plate is mounted between the electromagnetic valve body and the actuator valve body, the real-time hydraulic testing can be performed for a hydraulic control system under the condition of not changing the structure of the double-clutch transmission valve body; and the hydraulic testing device is simple in structure, is easy to operate, and is reliable and durable.
Description
technical field [0001] The invention relates to the technical field of automobile control, in particular to a hydraulic test device for a valve body of a dual-clutch gearbox. Background technique [0002] The dual-clutch automatic transmission can automatically change the transmission ratio according to the actual needs, so that the vehicle can obtain good power, reduce the pollution emission of the engine, and greatly improve the safety and reliability of driving. The valve body is an important control unit in the dual-clutch gearbox. In order to obtain a reliable, durable and efficient valve body, it generally needs to be tested repeatedly. Among them, the hydraulic test results are the best basis for evaluating the performance of the valve body. [0003] In the prior art, in order to test the pressure of the oil circuit of the valve body, it is common practice to drill holes on the valve body of the actuator or the valve body of the solenoid valve and install a pressure ...
