Problems solved by technology

[0010] In summary, the technical defect of the gearbox oil change equipment in the prior art is that the joint between the gearbox oil change equipment and the gearbox is relatively complicated, and a special joint is required to realize the oil change, which makes the purchase of the joint The cost is high, the assembly and disassembly takes a long time, and misoperation is prone to occur; the channel used by the oil change equipment in the prior art usually needs to pass through a thermostat, and the thermostat needs to reach a certain temperature before it can be opened, resulting in the limitation of the oil temperature. More stringent, which makes the structure of the oil change equipment more complicated; the oil volume in the gearbox is prone to abnormalities, which may cause the gearbox to be damaged

Abstract

The invention discloses a gearbox oil changing method and gearbox oil changing equipment. The gearbox oil changing method comprises the steps that 1, oil is pumped from a gearbox through a connector and an oil return pipeline; 2, oil is injected into the gearbox through the connector and an oil injection pipeline; and 3, the step 1 and the step 2 are repeatedly executed for multiple times. The gearbox oil changing method and gearbox oil changing equipment have the beneficial effects that the oil pumping process and the oil injection process are achieved through the same connector, the connecting mode between the gearbox and the gearbox oil changing equipment can be simplified, and the connecting mode and the connecting position between the connector and the gearbox are more flexible; the connector can extend into the gearbox through a liquid level observation opening of the gearbox, so that the connector is suitable for more vehicle types, the procurement cost of the connector is reduced, the assembly and disassembly working hours of the connector can be shortened, and the connection mis-operation risk of the connector can be reduced; and because the connector can be connected withthe gearbox through the liquid level observation opening, the oil liquid of the gearbox can be replaced by bypassing a thermostat. The invention relates to automobile maintenance.

Description

technical field [0001] The invention relates to automobile maintenance, in particular to a gearbox oil changing method and gearbox oil changing equipment. Background technique [0002] In order to make the oil change degree of the transmission oil change more thorough, the transmission usually needs to be kept running during the oil change process to keep the oil in the transmission in a state of agitation. If the oil is completely drained out of the gearbox, the gearbox is prone to damage during operation. Therefore, during the oil change process of the gearbox, it is necessary to keep the gearbox running, and it is also necessary to maintain a certain amount of oil in the gearbox. [0003] In the prior art, if you want to change the oil for the automatic transmission of an automobile, in addition to manually changing the oil by gravity draining, you can also use equipment to change the oil automatically. [0004] In the prior art, the principles of the mainstream oil cha...
