[0039] The content of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment 1

[0041] As Figure 1 and Figure 2As shown in the figure, a clutch housing with a transmission bearing lubrication function includes a clutch housing body 1, an input shaft bearing mounting hole seat 11, an intermediate shaft bearing mounting hole seat 21, and a bearing lubrication assembly. The input shaft bearing mounting hole seat 11 is provided on the housing body 1. An input shaft bearing mounting hole 18 is provided on the input shaft bearing mounting hole seat 11, and an input shaft bearing is installed in the input shaft bearing mounting hole 18. The intermediate shaft bearing mounting hole seat 21 is provided on the housing body 1. An intermediate shaft bearing mounting hole 26 is provided on the intermediate shaft bearing mounting hole seat 21, and an intermediate shaft bearing is installed in the intermediate shaft bearing mounting hole 26. The input shaft bearing mounting hole seat 11 is connected obliquely above the intermediate shaft bearing mounting hole seat 21. In the present invention, a bearing lubrication assembly is provided on the existing housing body 1, and the input shaft bearing and the intermediate shaft bearing in the clutch housing are fully lubricated through the bearing lubrication assembly.

[0042] The bearing lubrication assembly includes a first oil collecting rib plate 12, a second oil collecting rib plate 19, a third oil collecting rib plate 22, and an oil passage provided on the input shaft bearing mounting hole seat 11 and the intermediate shaft bearing mounting hole seat 21, specifically as follows:

[0043] Both the first oil collecting rib plate 12 and the second oil collecting rib plate 19 are located above the input shaft bearing mounting hole seat 11 and are vertically provided on the inner wall of the housing body 1. In this embodiment, both the first oil collecting rib plate 12 and the second oil collecting rib plate 19 are rectangular flat plates. In other embodiments, the cross-sections of the first oil collecting rib plate 12 and the second oil collecting rib plate 19 can be arc surfaces or curved surfaces, etc. Or, the first oil collecting rib plate 12 and the second oil collecting rib plate 19 can also be irregular shapes formed by splicing multiple flat plates. The upper ends of the first oil collecting rib plate 12 and the second oil collecting rib plate 19 both incline outwards, so that the first oil collecting rib plate 12 and the second oil collecting rib plate 19 are arranged in a V shape. The included angle β between the first oil collecting rib plate 12 and the second oil collecting rib plate 19 is 70° - 130°. To improve the lubrication effect, preferably, the included angle β between the first oil collecting rib plate 12 and the second oil collecting rib plate 19 is 90° - 130°. A first oil collecting area 13 located above the input shaft bearing mounting hole seat 11 is formed by enclosing between the side walls of the first oil collecting rib plate 12, the side walls of the second oil collecting rib plate 19, and the inner wall of the housing body 1. The first oil collecting area 13 is used to collect the lubricating oil stirred up by the rotation of the gears in the housing body 1. At the same time, there is a distance between the lower ends of the first oil collecting rib plate 12 and the second oil collecting rib plate 19, forming an oil outlet gap.

[0044] To lubricate the input shaft bearing within the input shaft bearing mounting hole seat 11, a first oil inlet channel 14 is provided radially along the top of the input shaft bearing mounting hole seat 11. The inlet end of the first oil inlet channel 14 communicates with the oil outlet notch, and the outlet end of the first oil inlet channel 14 communicates with the input shaft bearing mounting hole 18 of the input shaft bearing mounting hole seat 11, that is, the first oil collecting area 13 communicates with the input shaft bearing mounting hole 18 through the first oil inlet channel 14; a first oil outlet channel 15 is provided radially along the bottom of the input shaft bearing mounting hole seat 11. The inlet end of the first oil outlet channel 15 communicates with the input shaft bearing mounting hole 18 of the input shaft bearing mounting hole seat 11. Since the strength at the connection between the input shaft bearing mounting hole seat 11 and the intermediate shaft bearing mounting hole seat 21 is relatively low, in the present invention, the first oil outlet channel 15 is arranged deviating from the connection line of the centers of the input shaft bearing mounting hole seat 11 and the intermediate shaft bearing mounting hole seat 21, and it should be avoided to be arranged at the connection between the input shaft bearing mounting hole seat 11 and the intermediate shaft bearing mounting hole seat 21; in this embodiment, the first oil outlet channel 15 is located above the connection line of the centers of the input shaft bearing mounting hole seat 11 and the intermediate shaft bearing mounting hole seat 21.

[0045] To improve the lubrication effect of the input shaft bearing, a first oil inlet notch 16 is provided axially at a position corresponding to the first oil inlet channel 14 on the side wall (upper part) of the input shaft bearing mounting hole 18 of the input shaft bearing mounting hole seat 11. The depth of the first oil inlet notch 16 along the axis direction of the input shaft bearing mounting hole seat 11 is equal to the depth of the input shaft bearing mounting hole 18. Correspondingly, a first oil outlet notch 17 is provided axially at a position corresponding to the first oil outlet channel 15 on the side wall (lower part) of the input shaft bearing mounting hole 18 of the input shaft bearing mounting hole seat 11. The depth of the first oil outlet notch 17 along the axis direction of the input shaft bearing mounting hole seat 11 is equal to the depth of the input shaft bearing mounting hole 18.

[0046] The third oil collecting rib plate 22 is vertically arranged on the inner wall of the housing body 1. In this embodiment, the third oil collecting rib plate 22 is a rectangular flat plate. In other embodiments, the cross-sections of the first oil collecting rib plate 12 and the second oil collecting rib plate 19 can be arc surfaces or curved surfaces, etc.; or the third oil collecting rib plate 22 can also be an irregular shape formed by splicing multiple flat plates. The third oil collecting rib plate 22 and the input shaft bearing mounting hole seat 11 are respectively located on both sides of the center at the top of the intermediate shaft bearing mounting hole seat 21. The lower end of the third oil collecting rib plate 22 is connected to the outer wall of the intermediate shaft bearing mounting hole seat 21, and the upper end inclines outward; the side wall of the third oil collecting rib plate 22, the inner wall of the housing body 1, the side wall of the second oil collecting rib plate 19, the outer wall of the input shaft bearing mounting hole seat 11, and the outer wall of the intermediate shaft bearing mounting hole seat 21 enclose to form a second oil collecting area 23 above the intermediate shaft bearing mounting hole seat. The second oil collecting area 23 is used to collect the lubricating oil stirred up by the rotation of the gears within the housing body 1.

[0047] A second oil inlet passage 24 is provided radially along the top of the intermediate shaft bearing mounting hole seat 21. The inlet end of the second oil inlet passage 24 communicates with the second oil collecting area 23, and the outlet end communicates with the intermediate shaft bearing mounting hole 26 of the intermediate shaft bearing mounting hole seat 21. In this embodiment, the second oil collecting area 23 is used to lubricate the intermediate shaft bearing, which can avoid the problem that when a heavy truck is going uphill (when the transmission is going uphill), due to the inclination of the gearbox, the lubricating oil at the bottom inclines, resulting in poor lubrication effect of the intermediate shaft bearing.

[0048] In order to improve the lubrication effect of the intermediate shaft bearing, a second oil inlet notch 25 is provided axially at a position corresponding to the second oil inlet passage 24 on the side wall (upper part) of the intermediate shaft bearing mounting hole 26 of the intermediate shaft bearing mounting hole seat 21. The depth of the second oil inlet notch 25 along the axis direction of the intermediate shaft bearing mounting hole seat 25 is equal to the depth of the intermediate shaft bearing mounting hole 26. An oil outlet through hole 27 is provided at the bottom of the intermediate shaft bearing mounting hole seat 21, which is convenient for the lubricating oil to flow back into the transmission case body and avoid excessive lubricating oil around the bearing increasing energy consumption.

[0049] In order to improve the lubrication effect of the bearing, the first oil inlet passage 14 is located at the center of the top of the input shaft bearing mounting hole seat 11. Correspondingly, the first oil collecting rib plate 12 and the second oil collecting rib plate 19 are symmetrically arranged on both sides of the center of the top of the input shaft bearing mounting hole seat 11, that is, the lower ends of the first oil collecting rib plate 12 and the second oil collecting rib plate 19 are respectively connected to both sides of the first oil outlet passage 15 of the input shaft bearing mounting hole seat 11; the second oil inlet passage 24 is located at the center of the top of the intermediate shaft bearing mounting hole seat 21, the first oil outlet passage 15 communicates with the second oil inlet passage 24, and the second oil inlet passage 24 is lower than the first oil outlet passage 15.

[0050] In this embodiment, the upper ends of the first oil collecting rib plate 12, the second oil collecting rib plate 19, and the third oil collecting rib plate 22 are all connected to the inner wall of the joint surface 3 on the housing body 1.

[0051] The lubrication process of the input shaft bearing and the intermediate shaft bearing in this embodiment is as follows:

[0052] 1) Input shaft bearing

[0053] As Figure 3As shown, the arrow indicates the flow direction of the lubricating oil. The input shaft bearing is installed in the input shaft bearing mounting hole 18 within the clutch housing. When the transmission is operating, the lubricating oil splashed by the rotating gears inside the transmission hits the inner wall of the housing body 1. When it reaches the first oil collecting area 13, the lubricating oil in the first oil collecting area 13 will flow along the first oil collecting area 13 to the first oil inlet passage 14, and lubricate the input shaft bearing from the top through the first oil inlet passage 14 and the first oil inlet notch 16. The lubricating oil that lubricates the input shaft bearing finally flows out through the first oil outlet passage 15, then via the second oil inlet passage 24, and lubricates the countershaft bearing from the top through the second oil inlet passage 24 and the second oil inlet notch 25, and finally returns to the transmission housing under the action of gravity.

[0054] 2) Countershaft bearing

[0055] The countershaft bearing is installed in the countershaft bearing mounting hole 26 within the clutch housing. The lubricating oil source for the countershaft bearing is divided into two paths. One path is the lubricating oil that flows out from the first oil outlet passage 15 after lubricating the input shaft bearing, and the other path is the splashed lubricating oil collected by the second oil collecting area 23. Since the first oil outlet passage 15 and the second oil inlet passage 24 are interconnected and the second oil inlet passage 24 is lower than the first oil outlet passage 15, the lubricating oil that flows out from the first oil outlet passage 15 after lubricating the input shaft bearing will flow into the second oil inlet passage 24; and when the transmission is operating, the lubricating oil splashed by the rotating gears inside the transmission hits the inner wall of the housing body 1. When it reaches the second oil collecting area 23, the lubricating oil in the second oil collecting area 23 will flow along the second oil collecting area 23 to the second oil inlet passage 24. The above two paths of lubricating oil converge at the entrance of the second oil inlet passage 24, and lubricate the countershaft bearing from the top through the second oil inlet passage 24 and the second oil inlet notch 25, and finally return to the transmission housing under the action of gravity.

[0056] The bearing lubrication assembly of this embodiment is not only applicable to the lubrication and cooling of the transmission bearings, but also applicable to the lubrication and cooling of high-position or high-speed bearings in other products.

[0057] Embodiment 2

[0058] The difference from Embodiment 1 is that as Figure 4 and Figure 5As shown in the figure, a first fork shaft support boss 4 and a second fork shaft support boss 5 are provided on the housing body 1 of the clutch. Correspondingly, the first oil collecting rib plate 12 includes a first rib plate 121 and a second rib plate 122, and the first rib plate 121 and the second rib plate 122 are respectively connected to both sides of the first fork shaft support boss 4 on the housing body 1; the second oil collecting rib plate 12 includes a third rib plate 191 and a fourth rib plate 192, and the third rib plate 191 and the fourth rib plate 192 are respectively connected to both sides of the second fork shaft support boss 5 on the housing body 1. In practical applications, the formation of the oil collecting area is not limited to the inner wall of the oil collecting rib plate and the housing body 1, the outer wall of the input shaft bearing mounting hole seat 11, the intermediate shaft bearing mounting hole seat 21, and the outer wall of the fork shaft support boss, and can also be other components provided on the housing body 1 of the clutch.

[0059] The above only describes the preferred embodiments of the present invention and does not limit the technical solutions of the present invention thereto. Any well-known deformation made by those skilled in the art on the basis of the main technical concept of the present invention belongs to the technical scope to be protected by the present invention.
