Description

Technical Field

[0001] The utility model belongs to the technical field of gearboxes, and particularly relates to a new type of gearbox oil suction pipe structure integrated with a filter screen, a gearbox and a vehicle. Background Technique

[0002] In order to ensure the continuous and efficient normal operation of the gearbox, modern-designed gearboxes usually are equipped with an oil pan and a precision oil suction device specifically oriented towards the oil pan. This device can effectively transport the lubricating oil stored in the oil pan to the oil pump through suction, providing necessary lubrication and cooling for the gear system of the gearbox.

[0003] At the same time, in view of the increasing requirements of current users for the performance and reliability of the gearbox, ensuring the cleanliness of the gearbox gear oil has become an urgent problem to be solved. Therefore, many existing gearboxes have added lubricating oil filtering devices to further filter out impurities and particulate matters in the oil. However, it should be noted that most of the gearbox filter screens on the market are directly installed in the cavity of the gearbox housing. This not only requires additional filter screen installation structures and end cover sealing structures on the housing, but also often requires separate arrangement of the oil suction pipe and the filter screen, resulting in a relatively complex overall structure of the gearbox.

[0004] In addition, although some gearboxes integrate the filter screen on the oil suction pipe, since the oil pipe rotates during use, it is easy to cause damage to the pipe or the filter screen on the pipe, and then cause the oil with impurities to be transported into the oil pump, affecting the service life of the oil pump. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a new type of gearbox oil suction pipe structure integrated with a filter screen, a gearbox and a vehicle, and enable it to integrate the filter screen, the oil suction pipe and the anti-rotation structure together, so as to have the advantages of convenient installation, simple structure, high reliability, etc.

[0006] To solve the above technical problems, the technical solution provided by the present utility model is as follows: A new type of gearbox oil suction pipe structure integrated with a filter screen, which includes an oil suction pipe body with a Z-shaped trend. A rear end cover and a front end cover are fixedly installed on the outer wall of the oil suction pipe body in sequence along the direction of oil flow. A filter screen is fixed between the rear end cover and the front end cover. The filter screen is sleeved on the outside of the oil suction pipe body, and a through hole is provided at a position on the oil suction pipe body opposite to the filter screen. A plug is installed at the rear side of the through hole. On the one hand, since the present utility model directly integrates the filter screen on the oil suction pipe body and sets a plug at the rear side of the through hole, the present utility model can not only ensure that the lubricating oil can only enter the oil suction pipe through the filter screen during the oil suction process, thereby improving the cleanliness of the lubricating oil, as well as improving the efficiency and service life of the lubricating oil pump, but also has the advantages of compact structure, simplicity, and high integration; on the other hand, since the oil suction pipe body of the present utility model is designed with a Z-shaped trend, it can also play an anti-rotation effect through the shape of the oil suction pipe body itself, without the need to design additional anti-rotation structures, thereby further improving the integration and reliability of the entire oil suction pipe structure.

[0007] Further, the depth of the through hole is greater than the radius of the oil suction pipe body to ensure that the lubricating oil can smoothly enter the oil suction pipe.

[0008] Further, the front end cover and the rear end cover are welded and fixed on the outer wall of the oil suction pipe body and have good stability.

[0009] Further, both the front end cover and the rear end cover are eccentrically arranged on the outside of the oil suction pipe body.

[0010] Further, both ends of the filter screen are welded and fixed to the front end cover and the rear end cover and have good stability.

[0011] Further, flanges are provided on the outer rings of both the front end cover and the rear end cover. Both ends of the filter screen are welded and fixed to the corresponding flanges to ensure that the front end cover, the filter screen, and the rear end cover can be firmly connected together.

[0012] Further, the material of the filter screen is a metal material.

[0013] Further, the plug is welded and fixed in the inner hole of the oil suction pipe body and has good sealing performance.

[0014] On the other hand, the present utility model also provides a gearbox, which includes a gearbox body, and the above new type of gearbox oil suction pipe structure integrated with a filter screen is installed in the gearbox body.

[0015] In addition, the present utility model also provides a vehicle, which includes a vehicle body, and the above gearbox is installed on the vehicle body.

[0016] As can be seen from the above technical solutions, the present utility model has the following advantages: on the one hand, since the filter screen of the present utility model is directly integrally installed on the oil suction pipe body and a plug is provided at the rear side of the through hole, the present utility model can not only ensure that the lubricating oil can only enter the oil suction pipe through the filter screen during the oil suction process, thereby improving the cleanliness of the lubricating oil and the efficiency and service life of the lubricating oil pump, but also has the advantages of compact structure, simplicity and high integration; on the other hand, since the oil suction pipe body of the present utility model is designed to have a Z-shaped trend, it can also play an anti-rotation effect through the shape of its own oil suction pipe body, without the need to additionally design redundant anti-rotation structures, thereby further improving the integration and reliability of the entire oil suction pipe structure.

[0022] First Embodiment

[0023] As Figure 1 、 Figure 2 shown, the first embodiment provides a new type of integrated filter screen gearbox oil suction pipe structure, which includes an oil suction pipe body 1 with a Z-shaped trend. The outer wall of the oil inlet end of the oil suction pipe body 1 is sequentially welded and fixedly installed with a rear end cover 4 and a front end cover 2 along the oil flow direction. The rear end cover 4 and the front end cover 2 are both eccentrically arranged outside the oil suction pipe body 1, and flanges are provided on the outer rings of the front end cover 2 and the rear end cover 4, and a filter screen 3 made of metal is welded between the two flange structures.

[0024] The filter screen 3 is sleeved outside the oil suction pipe body 1, and through holes are formed at positions on the oil suction pipe body 1 opposite to the filter screen 3, and the depth of the through holes is greater than the radius of the oil suction pipe body 1. A plug 5 is welded and installed at a position on the inner cavity of the oil suction pipe body 1 behind the through holes, and the plug 5 is used to prevent the lubricating oil entering the oil suction pipe body 1 from flowing towards the rear side of the through holes.

[0025] When the lubricating oil is transported by using the first embodiment, the lubricating oil can be filtered by the filter screen 3 first, so as to block the impurity particles in the oil outside the filter screen 3 and prevent them from entering the inner cavity of the oil suction pipe body 1; then the filtered lubricating oil is prevented from entering the oil suction pipe body 1 from the rear end of the oil suction pipe body 1 by the plug 5, so as to ensure that the filtered lubricating oil can smoothly flow forward along the oil suction pipe body 1 and enter the oil pump. At the same time, during the whole transportation process, since the oil suction pipe body 1 in the first embodiment adopts a special Z-shaped trend, the oil suction pipe body 1 itself can also have an anti-rotation function through this shape, and there is no need to additionally provide other anti-rotation structures.

[0026] Based on this, the first embodiment can integrate the oil suction function, anti-rotation function and filtering function together, and has the characteristics of high integration, convenient installation, simple and compact structure, high reliability, etc., so it is widely used in the transmission field, especially in the automotive transmission field with high cleanliness.
