Description

Technical Field

[0001] The utility model particularly relates to a gearbox oil suction structure, which is used for sucking oil from a gearbox of a high-horsepower tractor. Background Art

[0002] The oil suction structure of existing high-horsepower tractors is as follows Figure 1 As shown, the main method is to cast an oil suction chamber 05 on the auxiliary tank housing 01, and then draw the oil from the oil pan 02 into the sleeve 03 through the oil suction port 06 of the oil suction chamber 05. The oil is then filtered by the coarse filter in the sleeve 03 before reaching the oil pump. Because the oil suction chamber 05 is directly cast on the auxiliary tank housing 01, the structure is limited by the casting process. At the same time, the interference with other parts during assembly must also be considered. It is necessary to ensure that the flow area of the oil suction chamber 05 is sufficient, that the oil suction chamber 05 does not interfere with other structures, and that the feasibility of casting is guaranteed. At the same time, due to the limitations of the oil suction chamber, when the auxiliary tank oil outlet 04 is raised, the oil suction chamber 05 cannot be raised to the same height at the same time, which will increase the length of the sleeve 03, resulting in structural waste and increasing the difficulty of casting.

[0003] Chinese patent CN215891018U discloses a "new transmission structure with a shared oil tank," comprising an oil pan, a first sleeve, a first sleeve oil inlet, an actuator oil inlet, a coarse filter mounting structure, and an operating mechanism oil inlet. The first sleeve and oil pan are connected via the first sleeve oil inlet. While this structure cleverly utilizes the oil pan space and reduces casting difficulty, it still fails to eliminate the oil suction cavity, resulting in an excessively long sleeve and a wasteful structure. Utility Model Content

[0004] The utility model aims to solve the technical problems of the existing gearbox that the limitation of the oil suction cavity leads to an increase in the sleeve length, resulting in structural waste and increased casting difficulty, and provides a gearbox oil suction structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A gearbox oil suction structure, the gearbox includes an auxiliary box housing, an oil pan and a sleeve arranged on the auxiliary box housing;

[0007] Its special features include: including oil pipes;

[0008] An oil pipe interface is provided on the outer wall of the sleeve;

[0009] The upper end of the oil pipe is connected to the sleeve through an oil pipe interface, and the lower end is inserted into the oil pan to suck the oil in the oil pan into the sleeve.

[0010] Furthermore, a sealing ring is provided between the upper end of the oil pipe and the sleeve.

[0011] Furthermore, the method further includes a plug and a through hole provided on the outer wall of the sleeve and opposite to the oil pipe interface; the plug is provided in the through hole to seal the through hole.

[0012] Furthermore, a sealing structure is provided on the end surface of the plug close to the sleeve.

[0013] Furthermore, the diameter of the through hole is larger than the diameter of the oil pipe interface.

[0014] Furthermore, the length of the oil pipe is 15cm-25cm.

[0015] Furthermore, the sealing structure is made of rubber material.

[0016] Beneficial effects of the utility model:

[0017] 1. The utility model provides a gearbox oil suction structure, which replaces the original oil suction chamber with an oil pipe, directly processes an oil pipe interface on the sleeve, and connects the oil pipe to the oil pipe interface. The position of the oil pipe interface and the length of the oil pipe can be arbitrarily adjusted according to the height of the oil outlet. In addition, the angle of the oil pipe can be adjusted according to the limitation of the internal structure of the gearbox sub-box to ensure that it does not interfere with other parts.

[0018] 2. The utility model provides a gearbox oil suction structure, which not only solves the problems of the existing oil suction chamber structure being difficult to cast and difficult to adjust, but also arranges the oil pipe inside the gearbox. Compared with other structures arranged outside the gearbox, it is easier to ensure its cleanliness and is less likely to cause the risk of external oil pipe collision. It has certain reference significance for the design of the oil suction structure of the gearbox of high-horsepower tractors.

[0019] 3. The utility model provides a gearbox oil suction structure with a simple structure, which reduces the difficulty of casting, saves the internal space of the gearbox, and facilitates the arrangement of other parts; the sleeve can be adjusted at will according to the height of the oil suction port position without being restricted by the structure of the oil suction chamber.
