[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0037] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] As described in the background technology, the related art provides a reducer in which an intermediate shaft assembly is located above the differential assembly and the input shaft assembly (i.e., the side away from the lubricating oil when in use), and its overall rotation direction is opposite to that of a conventional reducer. When the differential assembly rotates clockwise, the differential gear can throw a small amount of oil onto the intermediate shaft assembly, but compared with a conventional reducer, the lubrication condition of the intermediate shaft assembly is poor at this time. When the differential assembly rotates counterclockwise, the oil thrown up by the differential gear will be blocked by the driving gear on the intermediate shaft, so that only a very small amount of lubricating oil can be thrown to the bearing at the end of the intermediate shaft, so there is a risk of poor lubrication of the intermediate shaft assembly.

[0039] In view of this, the embodiments of the present application aim to provide a reducer lubrication assembly, a reducer, a transmission assembly and a vehicle, wherein a first oil guide groove and a first oil guide rib are arranged in a sealing end cover, the first oil guide groove is connected to the oil storage chamber of the first intermediate shaft bearing chamber, the first oil guide rib is connected to the first oil guide groove, the first oil guide groove and the first oil guide rib are both located between the intermediate shaft assembly and the differential assembly, when the differential assembly rotates counterclockwise, the first oil guide rib can guide the lubricating oil into the first oil guide groove, and then allow the lubricating oil to flow into the oil storage chamber of the first intermediate shaft bearing chamber, thereby improving the lubrication efficiency of the intermediate shaft assembly when the differential assembly rotates counterclockwise, and reducing the risk of poor lubrication of the intermediate shaft assembly.

[0040] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail.

The first direction X can be, for example, the direction of gravity, and the second direction Y can be, for example, the horizontal direction. Figure 1 for Figure 3 The mirror direction of Figure 2 for Figure 4 Mirror direction.

[0042] Please refer to Figure 1-Figure 4 , this embodiment provides a reducer lubrication assembly, which is arranged in a relatively connected sealing end cover 100 and a reducer housing 200, and the sealing end cover 100 and the reducer housing 200 are detachably connected, and the two together form a mounting cavity for accommodating the reducer. Specifically, the sealing end cover 100 is provided with a plurality of through holes around it, and the plurality of through holes can be evenly arranged along the circumference of the sealing end cover 100; the reducer housing 200 is provided with a plurality of fixing holes around it, and the plurality of fixing holes can be evenly arranged at one end of the reducer housing 200 facing the sealing end cover 100; the plurality of through holes correspond to the plurality of fixing holes one by one, and the fasteners are fixed in the corresponding fixing holes after passing through the through holes, thereby realizing the connection and fixation between the sealing end cover 100 and the reducer housing 200. When disassembly is required, the sealing end cover 100 and the reducer housing 200 can be separated by simply removing the fasteners.

[0043] The sealing end cover 100 of this embodiment includes a first bottom wall 101, a first side wall 102 and a second side wall 103. Along the first direction X, the first side wall 102 and the second side wall 103 are arranged opposite to each other, wherein the first side wall 102 is arranged away from the lubricating oil; that is, the lubricating oil is located on one side of the second side wall 103 in the use state. It can be understood that the sealing end cover 100 also includes other side walls connecting the first side wall 102 and the second side wall 103, so as to form a continuous sealing structure. The first bottom wall 101 is provided with a first intermediate shaft bearing chamber oil storage cavity 110 and a first differential assembly mounting hole 120, and the first intermediate shaft bearing chamber oil storage cavity 110 is located on the side of the first differential assembly mounting hole 120 facing the first side wall 102. The first intermediate shaft bearing chamber oil storage cavity 110 can be used to install the intermediate shaft assembly, and the first differential assembly mounting hole 120 can be used to install the differential assembly 10.

[0044] Furthermore, a first oil guide groove 130 and a first oil guide rib 140 are provided on the first bottom wall 101. The first oil guide groove 130 is connected to the first intermediate shaft bearing chamber oil storage cavity 110. The first oil guide rib 140 is connected to the first oil guide groove 130. Figure 1 and Figure 2 , along the first direction X, the first oil guide groove 130 and the first oil guide rib 140 are both located on the side of the first intermediate shaft bearing chamber oil storage cavity 110 facing the first side wall 102, and along the second direction Y, the first oil guide groove 130 and the first oil guide rib 140 are both arranged close to the first differential assembly mounting hole 120. The first oil guide rib 140 is used to rotate the differential assembly 10 counterclockwise ( Figure 2 The lubricating oil is guided into the first oil guide groove 130 when the differential assembly 10 rotates counterclockwise. It can be understood that when the differential assembly 10 rotates counterclockwise, the differential assembly 10 can throw the lubricating oil on the side of the second side wall 103 toward the first side wall 102. At this time, the first oil guide rib 140 can block the thrown lubricating oil, so that the lubricating oil flows into the first oil guide groove 130, and then the lubricating oil flows into the first intermediate shaft bearing chamber oil storage chamber 110, thereby improving the lubrication efficiency of the intermediate shaft assembly when the differential assembly 10 rotates counterclockwise and reducing the risk of poor lubrication of the intermediate shaft assembly.

[0045] In a possible implementation manner, the first oil guide groove 130 and the first oil guide rib 140 of this embodiment are both arranged at an angle, so as to better receive and guide the lubricating oil to flow into the first intermediate shaft bearing chamber oil storage cavity 110. Specifically, along the first direction X, the first end of the first oil guide groove 130 is arranged close to the first side wall 102, and along the second direction Y, the first end of the first oil guide groove 130 is arranged close to the first differential assembly mounting hole 120, and the second end of the first oil guide groove 130 is connected to the first intermediate shaft bearing chamber oil storage cavity 110. One end of the first oil guide rib 140 is connected to the first side wall 102, and the first oil guide rib 140 is parallel to the extension direction of the first oil guide groove 130.

[0046] Furthermore, the first oil guide rib 140 of this embodiment is located on a side of the first oil guide groove 130 away from the first differential assembly mounting hole 120, so that the lubricating oil thrown onto the surface of the first oil guide rib 140 can flow into the first oil guide groove 130 under the action of gravity. The angle between the first oil guide rib 140 and the second direction Y is greater than the climbing angle of the vehicle, so as to better receive the lubricating oil thrown up when the differential assembly 10 rotates counterclockwise.

[0047] In a possible implementation, the first bottom wall 101 of this embodiment is further provided with a second oil guide groove 150 and a second oil guide rib 160, the second oil guide groove 150 is connected to the first intermediate shaft bearing chamber oil storage chamber 110, and the second oil guide rib 160 is connected to the second oil guide groove 150.

The second oil guide rib 160 is used to guide the differential assembly 10 clockwise ( Figure 2 The lubricating oil is guided into the second oil guide groove 150 when the differential assembly 10 rotates clockwise. It can be understood that when the differential assembly 10 rotates clockwise, the differential assembly 10 can throw the lubricating oil on the side of the second side wall 103 toward the second oil guide rib 160. At this time, the second oil guide rib 160 can guide the thrown lubricating oil to flow into the second oil guide groove 150, and then the lubricating oil flows into the oil storage cavity 110 of the first intermediate shaft bearing chamber, thereby improving the lubrication efficiency of the intermediate shaft assembly when the differential assembly 10 rotates clockwise and reducing the risk of poor lubrication of the intermediate shaft assembly.

[0048] Furthermore, the second oil guide rib 160 of the present embodiment is arranged at an angle, so as to better receive and guide the lubricating oil to flow into the first intermediate shaft bearing chamber oil storage cavity 110. Specifically, along the first direction X, the first end of the second oil guide rib 160 is connected to the second side wall 103, and the second end of the second oil guide rib 160 is connected to the second oil guide groove 150; along the second direction Y, the first end of the second oil guide rib 160 is arranged close to the first differential assembly mounting hole 120, and the second end of the second oil guide rib 160 is located on the side of the first intermediate shaft bearing chamber oil storage cavity 110 away from the first differential assembly mounting hole 120.

The lubricating oil thrown up by the differential assembly 10 rises along the second oil guide rib 160 under the action of inertia, and the direction of the lubricating oil is changed after encountering the third oil guide rib 170, thereby entering the second oil guide groove 150.

[0050] Optionally, the angle between the third oil guide rib 170 of the present embodiment and the second direction Y is greater than the climbing angle of the vehicle, so as to better guide the lubricating oil into the second oil guide groove 150 .

[0051] Please continue to refer to Figure 3 and Figure 4 In a possible implementation, the reducer housing 200 of this embodiment includes a second bottom wall 201, a third side wall 202, a fourth side wall 203 and a fifth side wall 204. Along the first direction X, the third side wall 202 and the fourth side wall 203 are arranged opposite to each other, and the fifth side wall 204 connects the third side wall 202 and the fourth side wall 203, wherein the third side wall 202 is arranged away from the lubricating oil; that is, the lubricating oil is located on one side of the fourth side wall 203 in the use state. It can be understood that the sealing end cover 100 also includes another side wall opposite to the fifth side wall 204, thereby forming a continuous sealing structure. The second bottom wall 201 is provided with a second intermediate shaft bearing chamber oil storage cavity 210, a second differential assembly mounting hole 220 and an input shaft assembly mounting hole 230. Along the first direction X, the second intermediate shaft bearing chamber oil storage chamber 210 is located on the side of the second differential assembly mounting hole 220 and the input shaft assembly mounting hole 230 facing the third side wall 202, and along the second direction Y, the second intermediate shaft bearing chamber oil storage chamber 210 is located between the second differential assembly mounting hole 220 and the input shaft assembly mounting hole 230.

[0052] Further, the second bottom wall 201 is provided with a third oil guide groove 240, a fourth oil guide groove 250, a fifth oil guide groove 260, a fourth oil guide rib 270 and a fifth oil guide rib 280, wherein the third oil guide groove 240 and the fourth oil guide groove 250 are both connected to the input shaft assembly mounting hole 230, the fifth oil guide groove 260 is connected to the second intermediate shaft bearing chamber oil storage cavity 210, the fourth oil guide rib 270 is connected to the third oil guide groove 240, and the fifth oil guide rib 280 is arranged between the fourth side wall 203 and the fifth side wall 204 and connected to the fifth oil guide groove 260. Please refer to Figure 3 and Figure 4, along the first direction X, the third oil guide groove 240 and the fourth oil guide rib 270 are both arranged close to the fourth side wall 203; the fourth oil guide groove 250 is located on the side of the input shaft assembly mounting hole 230 away from the fourth side wall 203; the fifth oil guide groove 260 and the fifth oil guide rib 280 are located on the side of the fourth oil guide groove 250 away from the fourth side wall 203. Along the second direction Y, the third oil guide groove 240 and the fourth oil guide rib 270 are both located on the side of the input shaft assembly mounting hole 230 toward the second differential assembly mounting hole 220; the fifth oil guide groove 260 and the fifth oil guide rib 280 are both located on the side of the second differential assembly mounting hole 220 away from the second differential assembly mounting hole 220. The fourth oil guide rib 270 is used to rotate the differential assembly 10 clockwise ( Figure 4 The fourth oil guide groove 250 is used to guide the lubricating oil to flow to the fifth oil guide rib 280 when the input shaft assembly 20 rotates clockwise, and the fifth oil guide rib 280 is used to guide the lubricating oil into the fifth oil guide groove 260. It can be understood that when the differential assembly 10 rotates clockwise, the differential assembly 10 can throw the lubricating oil located on the side of the fourth side wall 203 toward the input shaft assembly 20. At this time, the fourth oil guide rib 270 can guide the thrown lubricating oil to flow into the third oil guide groove 240. The oil is temporarily stored in the oil pool of the input shaft assembly 20. When the input shaft assembly 20 rotates, the lubricating oil in the oil pool is thrown out through the fourth oil guide groove 250. The thrown lubricating oil is guided by the fifth oil guide rib 280 into the fifth oil guide groove 260, and then the lubricating oil flows into the oil storage cavity 210 of the second intermediate shaft bearing chamber, thereby improving the lubrication efficiency of the intermediate shaft assembly when the differential assembly 10 rotates clockwise and reducing the risk of poor lubrication of the intermediate shaft assembly.

[0053] Furthermore, in this embodiment, the angle between the fourth oil guide rib 270 and the second direction Y is a negative angle, so as to better guide the lubricating oil into the third oil guide groove 240. The fifth oil guide groove 260 and the fifth oil guide rib 280 are both arranged at an angle, so as to better receive and guide the lubricating oil into the oil storage cavity 210 of the second intermediate shaft bearing chamber. Specifically, along the first direction X, the first end of the fourth oil guide rib 270 is connected to the fourth side wall 203, the second end of the fourth oil guide rib 270 is connected to the third oil guide groove 240, and the fifth oil guide groove 260 is connected to the middle part of the fifth oil guide rib 280. Along the second direction Y, the first end of the fourth oil guide rib 270 is arranged close to the second differential assembly mounting hole 220, and the second end of the fourth oil guide rib 270 is arranged away from the second differential assembly mounting hole 220.

[0054] Furthermore, in order to better guide the lubricating oil into the fifth oil guide groove 260, a sixth oil guide rib 290 is further provided in the fifth oil guide groove 260 of the present embodiment, one end of the sixth oil guide rib 290 is connected to the fifth oil guide rib 280, and the other end extends toward the oil storage cavity 210 of the second intermediate shaft bearing chamber, and the sixth oil guide rib 290 is parallel to the extension direction of the fifth oil guide groove 260. The lubricating oil thrown up by the input shaft assembly 20 rises along the fifth oil guide rib 280 under the action of inertia force, and the direction of the lubricating oil is changed after encountering the sixth oil guide rib 290, thereby entering the fifth oil guide groove 260.
