Abstract

Provided is a hydraulic workstation for speed changing box testing. A speed changing box oil pump in an oil supply system is in driven connection with a driving motor, a hydraulic module is connected with the speed changing box oil pump and an oil tank pipeline respectively, a cooler in a cooling system is connected with the input end and the output end of a hydraulic module cooling pipeline, the control end of the hydraulic module is connected with a control module, and the output end of the hydraulic module is connected with a flowmeter and a pressure sensor. The hydraulic workstation integrates actual oil supply and cooling modes, a suction filter, an oil pump, a cooler and other parts of a dual-clutch speed changing box and is further suitable for hydraulic module basic function testing under actual working condition.

Description

technical field [0001] The invention relates to a gearbox testing hydraulic work station. Background technique [0002] At present, dual-clutch gearboxes on the market generally adopt electronically controlled hydraulic control methods. This type of gearbox realizes the distribution of oil at each function port through hydraulic module control, and then transfers the oil to the required position of each component. [0003] Although the oil supply system and cooling system used in the existing test bench hydraulic workstation can meet the requirements of use, there are certain differences between its functional parameters and the actual state of the gearbox. The deviation of the test results caused by this part of the factor will affect the gearbox. The accuracy of the actual work process control. [0004] In addition, each function port at the output end of the hydraulic workstation is currently connected to the required sensors. When this function port needs to be combined...
