Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to a hybrid power gearbox valve body structure. Background Art

[0002] The interior of the gearbox is filled with oil. The valve body is a key component in the gearbox that plays a key role in shifting gears and is placed at the inner bottom of the gearbox. The oil inlet of the valve body is provided with a filtering structure. The oil in the gearbox enters the valve body from the oil inlet of the valve body to prevent impurities from entering the valve body when the oil is entering.

[0003] However, the current filtering mechanism of the valve body is too simple, and only relies on the filter to filter the transmission oil. It does not have the function of automatically cleaning the impurities on the filter. There will be impurities such as iron filings at the inner bottom of the gearbox. As the transmission oil flows, the impurities will gradually accumulate on the surface of the filter, thereby clogging the filter, and then affecting the transmission oil pass rate, causing poor oil pressure in the valve body, and then causing the clutch, brake and other shift actuators to slip, affecting the normal operation of the automatic transmission, and accelerating the wear of the clutch and brake friction plates. In severe cases, it will cause the friction plates to burn out, etc., and thus a hybrid transmission valve body structure is proposed. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a hybrid power transmission valve body structure, including a hybrid power transmission valve body plate 1, an oil channel 2 is opened on the surface of the hybrid power transmission valve body plate 1, and the flow channel of the transmission oil in the transmission is opened. The inner wall of the oil channel 2 is slidably connected with a filter frame 3, and the inner wall of the filter frame 3 is fixedly connected with a filter 4, which can filter and block impurities in the transmission oil.

[0024] Frame-shaped slide grooves 12 are provided on both sides of the inner wall of the filter frame 3, and a cleaning mechanism is arranged inside the oil channel 2, which includes a moving frame 10, and moving rods 11 are fixedly connected on both sides of the moving frame 10, and the surfaces of the two moving rods 11 are respectively slidably connected to the inner walls of the two slide grooves 12, and a cleaning plate 9 is fixedly connected to the side of the moving frame 10 close to the filter 4, and the surface of the cleaning plate 9 is slidably connected to the surface of the filter 4, and the surface of the cleaning plate 9 is slidably connected to the inner wall of the filter frame 3, and the lower side of the cleaning plate 9 is an inclined surface, so that impurities attached to the surface of the filter 4 can be better removed, and a collecting groove 15 is provided on the surface of the cleaning plate 9 for collecting the removed impurities to a certain extent, thereby reducing the content of impurities in the transmission oil and reducing the difficulty of subsequent filtering of impurities in the transmission oil.

[0025] The inner wall of the oil passage 2 is rotatably connected with a rotating shaft 6, the surface of the rotating shaft 6 is fixedly connected with an L-shaped connecting rod 7, the surface of the connecting rod 7 is slidably connected with a sliding sleeve 8, the surface of the sliding sleeve 8 is slidably connected to the inside of the moving frame 10, and the surface of the rotating shaft 6 is fixedly connected with a turbine 5, and then through the setting of the turbine 5, the flow of transmission oil in the hybrid transmission valve body plate 1 can be used to impact the turbine 5, thereby driving the rotating shaft 6 to rotate, thereby providing a power source for the operation of the device.

[0026] Furthermore, the inner wall of the slide groove 12 is slidably connected to two push plates 14 with a trapezoidal cross-section, and the surface of the push plates 14 is also slidably connected to the inside of the filter frame 3. The two push plates 14 are diagonally arranged in the slide groove 12 and are oppositely arranged at the same time. The opposite sides of the two slide grooves 12 are fixedly connected to springs 13, and the ends of the two springs 13 away from the two push plates 14 are fixedly connected to the inside of the filter frame 3 for resetting the push plates 14.

[0027] Furthermore, when the device is used, the flow of transmission oil impacts the turbine 5, thereby driving the rotating shaft 6 to rotate, and then driving the connecting rod 7 to make a circular motion, and then pushing or pulling the moving frame 10 to make an up and down reciprocating motion in the filter frame 3 through the sliding sleeve 8, thereby driving the cleaning plate 9 to make an up and down reciprocating motion on the surface of the filter 4, so that the cleaning plate 9 removes the impurities attached to the surface of the filter 4 and enters the collecting tank 15 along the inclined surface of the cleaning plate 9. Therefore, through the setting of the cleaning mechanism, the impurities on the filter 4 in the hybrid transmission valve body plate 1 can be cleaned when the hybrid transmission valve body plate 1 is running, thereby avoiding the situation where the transmission oil passing rate in the hybrid transmission valve body plate 1 is reduced, the oil pressure is poor, and the normal operation of the transmission is affected, and the filter 4 can be automatically cleaned, thereby ensuring the normal operation of the transmission, which has a high promotion significance.

[0028] The moving frame 10 moves up and down, thereby driving the moving rod 11 to move up and down in the slide groove 12. When the moving rod 11 gradually moves to the push plate 14 below the slide groove 12 during the descending process, the surface of the moving rod 11 squeezes the inclined surface of the push plate 14, thereby pushing the push plate 14 to slide in the slide groove 12 and compressing the spring 13, so that the push plate 14 no longer hinders the descent of the moving rod 11. As the moving rod 11 descends, the moving rod 11 moves to the horizontal groove below the slide groove 12. At this time, under the elastic force of the spring 13, the push plate 14 pushes the moving rod 11 so that the moving rod 11 is located in the other vertical groove of the slide groove 12, thereby driving the moving frame 10 and the cleaning plate 9 to move, so that the cleaning plate 9 and the filter screen 4 are separated from each other, and at the same time, the sliding sleeve 8 and the connecting rod 7 are pushed to slide against each other, so that as the rotating shaft 6 rotates, the moving rod 11 moves along the slide groove When the cleaning plate 9 is lifted up, the impurities on the surface of the filter screen 4 are prevented from being pushed up by the cleaning plate 9 during the lifting process, thereby preventing the impurities on the filter screen 4 from being accumulated on the top of the filter screen 4 and being unable to be cleaned, thereby ensuring the cleaning effect of the device on the filter screen 4.

[0029] Working principle: The flow of transmission oil impacts the turbine 5, thereby driving the rotating shaft 6 to rotate, and then driving the connecting rod 7 to make a circular motion, and then pushing or pulling the moving frame 10 to reciprocate up and down in the filter frame 3 through the sliding sleeve 8, thereby driving the cleaning plate 9 to reciprocate up and down on the surface of the filter 4, so that the cleaning plate 9 can remove the impurities attached to the surface of the filter 4, and enter the collection tank 15 along the inclined surface of the cleaning plate 9.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
