Problems solved by technology
[0007] The purpose of the present invention is to overcome the shortcomings of the prior art, and provides a gearbox filling oil circulation equipment, which can automatically refuel and pump oil, and can quantitatively refill and make the oil pressure in the pipeline meet the pressure requirements. The cold oil tank, the heating oil tank and the plate heat exchanger are used to control the temperature of the oil through the program and the circulation of the oil pump. The heating adopts the indirect heating mode of heat transfer oil, which can avoid the damage of the oil caused by direct heating; through the switching between the valves, the oil can be filled The entire oil filling pipeline is filled to achieve flow calibration; by using a vacuum pump to pump oil, the oil pumping is fast and the margin is low. The invention solves the technical problems of the existing gearbox oil filling circulation equipment that is easy to damage oil products and poor filtering effect

Embodiment 1
[0044] Such as figure 1 Shown:
[0045] In this embodiment, the gearbox 1 is arranged on a test bench, and the gearbox 1 is connected to the heating oil tank 13 through the gearbox oil filling pipeline 2;
[0046] One end of the gearbox oil filling pipeline 2 close to the gearbox 1 is provided with a solenoid valve-3; the end of the gearbox oil filling pipeline 2 close to the heating oil tank 13 is provided with a gear pump 12; There is a filter section one 9 between them; a pressure sensor two 11 is also provided between the filter section one 9 and the gear pump 12; a manual manual is also arranged in turn between the filter section one 9 and the solenoid valve one 3 along the direction of liquid flow. Stop valve, pressure sensor one 8, solenoid valve and flow meter 7; oil is filled into the gearbox 1 through the quantitative filling form of the gear pump 12, and it will stop automatically when the filling reaches the preset amount.
[0047] One end of the gearbox oil suct...

The invention provides a gearbox filling oil circulation device, which relates to the technical field of gearbox testing. The transmission filling oil circulation equipment includes a transmission (1), a transmission oil suction pipe (4), an external circulation pipe (6), a heating oil tank (13), a cold oil tank (14), a dirty oil tank (25), and an oil supply pipe (34) and the waste oil tank (44), the gear pump (12) is used for oil filling, the vacuum pump (28) is used for oil pumping, and the oil is heated by indirect heating, and the cooling circulation pipeline (16) and plate heat exchange are combined The device (17) is used for temperature control, and the dirty oil is filtered and recycled through the multi-stage filter device, which solves the technical problems of the existing transmission oil filling cycle equipment that easily damages the oil product and poor filtering effect.
Description
technical field [0001] The invention relates to the technical field of gearbox testing, in particular to a gearbox filling oil circulation device. Background technique [0002] Gearbox is an important part of a car. Gearbox failure directly affects people's driving experience of the car. Gearbox failure will make the whole vehicle unable to run, and even cause safety accidents in severe cases. In recent years, people usually use the method of road test to diagnose and analyze gearbox faults. However, people simply operate the gearbox when the car is running on the road, and judge whether the gearbox is faulty or not by the operation of the whole vehicle. Fault, but this is often not able to accurately determine the fault of the gearbox. [0003] When developing and maintaining the gearbox, the gearbox will be pumped and filled with oil, so as to test the various parameters of the gearbox, which provides convenience for the inspection and maintenance of the gearbox. In the ...
