Description

Technical Field

[0001] The utility model relates to the technical field of gearbox housings, and in particular to a gearbox housing for a new energy vehicle. Background Art

[0002] The transmission is a key component in enabling reverse driving. Since a car engine's crankshaft typically rotates only in one direction, a reverse gear is built into the transmission to facilitate this function. When the driver selects reverse gear, the transmission changes the direction of the engine's rotation, allowing the car to travel in reverse. This allows the car to reverse even when the engine's crankshaft rotates only in one direction. New energy vehicles also utilize transmissions to improve their high-speed performance. However, due to the higher motor speeds, new energy vehicle transmissions are more prone to metal debris. Excessive metal debris can affect the transmission's performance and reduce the life of the gears within it.

[0027] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1: Figure 1-5As shown, a new energy vehicle gearbox housing includes a housing 1, a filter area 4 is opened on one side of the housing 1, a plurality of filter holes 3 are opened on one end of the housing 1 and the filter area 4, a partition 21 is fixedly connected to one end of the filter area 4, a filter plate 7 is fixedly connected to the inside of the filter area 4, a synchronous wheel 9 is rotatably connected to one side of the partition 21, a synchronous belt 11 is transmission-connected to one end of the synchronous wheel 9, a scraper 8 is rotatably connected to one end of the synchronous belt 11, a limit bracket 10 is slidably connected to the other side of the housing 1, and one end of the limit bracket 10 is slidably connected to the scraper 8, and a sedimentation tank 5 is opened on one side of the filter area 4;

[0030] When the gearbox is in use, the internal oil enters the filter area 4 through the filter hole 3, and then passes through the filter plate 7 to filter the metal debris in the oil. After the debris accumulates on the surface of the filter plate 7, the synchronous wheel 9 rotates to drive the synchronous belt 11 to rotate. At this time, the scraper 8 can be driven to rotate along the rotation trajectory of the synchronous belt 11. When it is close to the side of the filter plate 7, the debris can be scraped down to the sedimentation tank 5 for accumulation. The sedimentation tank 5 can be cleaned regularly by opening a cover on one side. When the scraper 8 moves upward, it is located away from the filter plate 7 and does not contact the filter plate 7. At the same time, the limit bracket 10 moves up and down with the scraper 8. Because the edge of the limit bracket 10 is square and will not rotate, the scraper 8 can be stabilized in a parallel state and will not rotate for easy scraping.

[0031] In this embodiment, one end of the filter plate 7 is rotatably connected to a paddle 12, and one end of the paddle 12 is fixedly connected to the drive shaft 6. When the drive shaft 6 rotates, the paddle 12 can rotate to accelerate the flow of oil and prevent the oil from standing still and reducing the filtering effect.

[0032] In this embodiment, one end of the partition 21 is rotatably connected to the bevel gear 15 and the bevel gear set 14, the bevel gear set 14 and one end of the bevel gear 15 are meshed with each other, and the drive shaft 6 and one end of the bevel gear set 14 are connected through a drive chain 13;

[0033] One side of the partition 21 is rotatably connected to a synchronous sprocket 22, one end of the synchronous sprocket 22 on one side is fixedly connected to the bevel gear 15, and one end of the synchronous sprocket 22 on the other side is fixedly connected to the synchronous wheel 9, and one end of the synchronous sprocket 22 is transmission-connected to a synchronous chain 23;

[0034] The drive shaft 6 and one end of the bevel gear set 14 have a sprocket, which can be connected through a drive chain 13. At the same time, the bevel gear 15, the synchronous sprocket 22 and the synchronous chain 23 drive the synchronous wheel 9 to rotate, so that the blade 12 and the scraper 8 start synchronously to improve the filtration efficiency.

[0035] In this embodiment, when the gearbox is in use, the internal oil enters the filter area 4 through the filter hole 3, and then passes through the filter plate 7 to filter the metal debris in the oil. After the debris accumulates on the surface of the filter plate 7, the synchronous wheel 9 rotates to drive the synchronous belt 11 to rotate. At this time, the scraper 8 can be driven to rotate along the rotation track of the synchronous belt 11. When it is close to the side of the filter plate 7, the debris can be scraped down and accumulated in the sedimentation tank 5. The sedimentation tank 5 can be cleaned regularly by opening a cover on one side. When the scraper 8 moves upward, it is located away from the filter plate 7 and does not contact the filter plate 7. At the same time, the limiting bracket 10 moves up and down with the scraper 8. Because the edge of the limiting bracket 10 is square and does not rotate, it can stabilize the scraper 8 in a parallel state and does not rotate for easy scraping.

[0036] When the drive shaft 6 rotates, the blades 12 can rotate to accelerate the flow of oil, preventing the oil from standing still and reducing the filtering effect;

[0037] The drive shaft 6 and one end of the bevel gear set 14 have a sprocket, which can be connected through a drive chain 13. At the same time, the bevel gear 15, the synchronous sprocket 22 and the synchronous chain 23 drive the synchronous wheel 9 to rotate, so that the blade 12 and the scraper 8 start synchronously to improve the filtration efficiency.

[0038] Example 2: This example makes the following improvements based on Example 1. In this example, multiple cooling pipes 2 are fixedly connected to the outside of the housing 1, and a cooling assembly 20 is fixedly connected to one end of the cooling pipe 2. Coolant is retained in the cooling pipe 2 to reduce the temperature. The cooling assembly 20 can cool the coolant and then pump it out;

[0039] An impeller groove 19 is formed at one end of the cooling pipe 2 on one side, and a hydraulic torque converter 17 is fixedly connected to the other end of the cooling pipe 2. A driving impeller 18 is fixedly connected to the power input end of the hydraulic torque converter 17. A driving chain 2 16 is transmission-connected to the power output end of the hydraulic torque converter 17. One end of the driving chain 2 16 is transmission-connected to the drive shaft 6.

[0040] When the coolant flows, it drives the impeller groove 19 to rotate, thereby driving the torque converter 17 to drive the drive shaft 6 through the drive chain 16 to rotate to achieve cleaning. No additional power source is required, and the torque converter 17 can prevent jamming.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
