[0053] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0054] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] The oil pipe structure 100 , a gearbox, a powertrain, and a vehicle according to an embodiment of the present utility model are described below with reference to the accompanying drawings.

[0056] like Figure 1 , Figure 2As shown, the oil pipe structure 100 according to the embodiment of the utility model is applied to a gearbox, and includes a pipeline 1, the pipeline 1 includes an inlet end 100a suitable for connecting to an oil pump, a first outlet end 100b suitable for communicating with a first oil circuit in the gearbox, and a second outlet end 100c suitable for communicating with a second oil circuit in the gearbox. A flow channel is provided in the pipeline 1, and the inlet end 100a, the first outlet end 100b and the second outlet end 100c are respectively communicated with the flow channel.

[0057] It can be understood that the lubricating oil can flow in the flow channel in the pipeline 1, and the flow channel extends along the pipeline 1, so that the lubricating oil enters the pipeline 1 from the inlet end 100a under the drive of the oil pump and is transported in the flow channel along the pipeline 1 to the first oil circuit and the second oil circuit in the gearbox, and the first oil circuit and the second oil circuit can transport the lubricating oil to different positions in the gearbox.

[0058] Compared with the splash lubrication solution, the oil pipe structure 100 of the present application enables the lubricating oil to flow along the flow channel in the pipeline 1, so that the lubricating oil can be transported to the first oil circuit and the second oil circuit of the gearbox through the pipeline 1, and then transported to the designated position through the first oil circuit and the second oil circuit, so as to achieve stable transportation of the lubricating oil and transport the lubricating oil to different positions, thereby reducing the parts in the gearbox that are insufficiently lubricated or cannot be lubricated.

[0059] In addition, structures such as oil guide grooves or oil baffles can be reduced in the gearbox. Compared with the structure of splash lubrication set in the gearbox, the oil pipe structure 100 can have a higher degree of integration and a smaller volume.

[0060] At the same time, an inlet end 100a, a first outlet end 100b, and a second outlet end 100c are provided on the pipeline 1, so that the lubricating oil is diverted to the first oil circuit and the second oil circuit in the pipeline 1. The lubricating oil flow path is diverted on the pipeline 1. Compared with the solution in which the lubricating oil flow path is diverted in the oil circuit of the gearbox, the internal flow path structure of the gearbox is simplified, thereby reducing the processing cost of the gearbox case 50.

[0061] In the present application, there is no limitation on the setting position of the pipeline 1 in the gearbox, and the extension position of the pipeline 1 in the gearbox can be set according to requirements.

[0062] The oil pipe structure 100 of the present application can be configured to cooperate with splash lubrication. Splash lubrication can be configured at a position in the gearbox where the oil pipe structure 100 cannot be configured. Thus, through the coordination of the oil pipe structure 100 and splash lubrication, the lubricating oil can be stably delivered to more positions in the gearbox.

[0063] In some embodiments, Figure 1 , Figure 2 The pipeline 1 comprises: at least one pipe body 10, and a flow channel is arranged in the pipe body 10.

[0064] A pipe column is fixedly connected to the pipe body 10, the pipe column extends along the first direction, the pipe column is not parallel to the pipe body 10, and a connecting cavity connected to the flow channel is arranged in the pipe column; at least one of the inlet end 100a, the first outlet end 100b and the second outlet end 100c is formed on one end of the pipe column along the first direction.

[0065] Furthermore, a base is fixedly arranged at the other end of the pipe column along the first direction, and at least one connector connected to the gearbox is arranged on the base.

[0066] It can be understood that the lubricating oil can flow in the flow channel within the tube body 10, and the flow channel can extend with the tube body 10 and flow into the connecting cavity in the pipe column, so that the lubricating oil can flow in the connecting cavity along the pipe column in a first direction, so that the lubricating oil can flow along the tube body 10 and the pipe column in the oil pipe structure 100, so that the lubricating oil can be transported to different tube bodies 10 through pipelines, and transported to the first oil circuit or the second oil circuit in the gearbox through different tube bodies 10.

[0067] Therefore, by setting a tube body 10 and a tube column extending in different directions, setting a flow channel in the tube body 10, and setting a connecting cavity in the tube column, the lubricating oil can flow in the tube body 10 and the tube column, so that the lubricating oil can be transported to different positions of the gearbox through the tube body 10 and the tube column, so as to achieve stable transportation of the lubricating oil.

[0068] In the present application, there is no limitation on the arrangement positions of the pipe column and the pipe body 10 in the gearbox, and the extension positions of the pipe body 10 and the pipe column in the gearbox can be set according to requirements.

[0069] In some embodiments, Figure 1 , Figure 2 As shown, the connector includes a guide post 32 fixedly arranged on the surface of the base away from the pipe column, and the guide post 32 is used to be plugged into the gearbox, and the gearbox is provided with a guide hole plugged with the guide post 32. Alternatively, the connector includes a pin hole 31 arranged on the base and a pin inserted in the pin hole 31, and the gearbox is provided with a plug hole plugged with the pin.

[0070] Thus, through the cooperation between the guide column 32 and the guide hole, or through the cooperation between the pin shaft and the plug hole, multiple bases can be positioned at different positions on the gearbox, thereby fixing the setting position of the oil pipe structure 100 on the gearbox. The positioning of the base on the gearbox is achieved by plug-in cooperation, which has a simple structure and is easy to operate.

[0071] Further, the pipe column includes a first end away from the pipe body 10 and a second end adjacent to the pipe body 10, and at least one external interface includes a first external interface 14 fixedly arranged on the first end, the first external interface 14 faces the side away from the base, and the first external interface 14 forms any one of an inlet end 100a, a first outlet end 100b, and a second outlet end 100c. Thus, the lubricating oil flows out of the pipe column through the first external interface 14. In addition, the pipeline can be externally connected to the first external interface 14, thereby extending the pipeline and guiding the lubricating oil to a position that is difficult for the pipe column to reach. For example, by connecting a hose to the first external interface 14 or connecting the first external interface 14 to the oil guide groove in the gearbox, the flow direction of the lubricating oil can be more accurately controlled.

[0072] In some embodiments, Figure 1 , Figure 2 As shown, the pipe column includes a first pipe column 11, and the base includes a first base 21. A first external interface 14 is provided on the first end of the first pipe column 11, and the first external interface 14 on the first pipe column 11 forms an inlet end 100a. The second end of the first pipe column 11 is fixedly connected to the first base 21, and the first base 21 is provided with a guide column 32 on the surface away from the first pipe column 11. Therefore, the first base 21 is plugged into the corresponding guide hole on the gearbox through the guide column 32 to realize the positioning of the first base 21 on the gearbox, and the first pipe column 11 extends in a direction away from the first base 21, so that the lubricating oil can flow in a direction away from the first base 21, and the first base 21 will not block the flow of the lubricating oil in the first pipe column 11.

[0073] In some embodiments, Figure 1 , Figure 2 As shown, the pipe column includes a second pipe column 12, and the base includes a second base 22. A first external interface 14 is provided on the first end of the second pipe column 12, and the first external interface 14 on the second pipe column 12 forms a first outlet end 110b. The second end of the second pipe column 12 is fixedly connected to the second base 22, and the second base 22 is provided with a guide column 32 and a pin hole 31 on the surface away from the second pipe column 12.

[0074] Thus, the second base 22 is inserted into the corresponding guide hole on the gearbox through the guide column 32, and the corresponding pin on the gearbox can be inserted into the pin hole 31 on the second base 22, so as to realize the positioning of the second base 22 on the gearbox. The second pipe column 12 extends in a direction away from the second base 22, so that the lubricating oil can flow in a direction away from the second base 22, and the second base 22 will not block the flow of the lubricating oil in the second pipe column 12.

[0075] It is understandable that in Figure 1 , Figure 2In the example, the second base 22 is located in the middle of the tube body 10, and needs to withstand greater stress relative to the two ends of the tube body 10, so the second base 22 is provided with a guide column 32 and a pin hole 31 at the same time, so that the second base 22 can be more stably limited on the gearbox, thereby improving the stability of the oil guide structure on the gearbox.

[0076] In some embodiments, Figure 2 As shown, the pipe column includes a third pipe column 13, and the base includes a third base 23. The first end of the third pipe column 13 is fixedly connected to the pipe body 10, and the first external interface 14 on the third pipe column 13 forms the second outlet end 100c. The second end of the third pipe column 13 is fixedly connected to the third base 23, and the third base 23 is provided with a first external interface 14 and a pin hole 31 on the surface away from the third pipe column 13. Therefore, the pin shaft correspondingly provided on the gearbox is inserted into the pin hole 31 on the third base 23 to realize the positioning of the third base 23 on the gearbox, and the first external interface 14 and the third base 23 are located on the same side of the pipe body 10, so that the lubricating oil in the pipe body 10 can flow from the connecting cavity through the third base 23 and flow to the second outlet end 100c.

[0077] In some embodiments, Figure 1 , Figure 2 As shown, the outer wall of the tube body 10 includes a first interface and a second interface connected to the communication cavity, the first interface is fixedly connected to the pipe column, and a plugging portion 41 is provided on the second interface, and the axis of the plugging portion 41 is colinear with the axis of the tube body 10. An extension cavity connected to the communication cavity is provided in the plugging portion 41, and the extension cavity is sealed at one end away from the tube body 10.

[0078] It can be understood that the flow channel in the tube body 10 is connected to the connecting cavity in the pipe column at the first interface, and at least part of the lubricating oil flowing in the tube body 10 can change its flow direction at the first interface and flow into the connecting cavity of the pipe column.

[0079] Therefore, by setting an extension cavity formed in the sealing portion 41 at the second interface, the lubricating oil can flow into and fill the extension cavity through the second interface, so that when the lubricating oil flows to the first interface and turns, since the extension cavity at the second interface opposite to the first interface is filled with lubricating oil, the resistance encountered by the lubricating oil when the flow direction changes at the first interface can be reduced, thereby improving the efficiency of lubricating oil transportation in the oil pipe structure 100.

[0080] In some embodiments, Figure 1 , Figure 2 As shown, at least one reinforcing rib 42 is provided between the pipe column and the base. Thus, the provision of the reinforcing rib 42 enables the base to have a better stress absorption effect, thereby improving the structural strength of the base and the connection stability between the base and the pipe column.

[0081] In some embodiments, Figure 1 , Figure 2 As shown, the pipe body 10 or the pipe column is provided with a nozzle 43 connected to the flow channel, or both the pipe body 10 and the pipe column are provided with a nozzle 43 connected to the flow channel. Thus, the lubricating oil can be released through the nozzle 43 at the position where the pipe body 10 and the pipe column pass.

[0082] In some embodiments, Figure 1 , Figure 2 As shown, the pipeline 1 includes a pipe body 10 and a first pipe column 11, a second pipe column 12, and a third pipe column 13 respectively orthogonal to the pipe body 10, an inlet end 100a is formed at one end of the first pipe column 11, a first outlet end 100b is formed at one end of the second pipe column 12, and a second outlet end 100c is formed at one end of the third pipe column 13.

[0083] Thus, the lubricating oil can be input into the tube body 10 through the first tube column 11, and transported to different positions in the gearbox through the second tube column 12 and the third tube column 13. In addition, by arranging the first tube column 11, the second tube column 12, and the third tube column 13 to be orthogonal to the tube body 10, the shape of the pipeline 1 can be better matched with the shape of the gearbox, and it is suitable to connect the oil circuits at different positions in the gearbox through the second tube column 12 and the third tube column 13, thereby increasing the lubrication positions of the lubricating oil in the gearbox.

[0084] In some embodiments, the tube body 10 is configured as a straight tube, which can improve the strength stability of each part of the tube body 10, thereby reducing the deformation of the tube body 10 and improving the stability of the pipeline 1 in transporting lubricating oil.

[0085] According to the gearbox of the embodiment of the utility model, the gearbox comprises a box body 50 and the oil pipe structure 100 of the above embodiment, and the oil pipe structure 100 is fixed on the box body 50. The box body 50 encloses a receiving cavity, and the oil pipe structure 100 is located in the receiving cavity.

[0086] According to the gearbox of the embodiment of the utility model, by adopting the oil pipe structure 100 of the above embodiment, the lubricating oil can flow in the pipeline 1 along the flow channel, so that the lubricating oil can be transported to the first oil circuit and the second oil circuit of the gearbox through the pipeline 1, so as to achieve stable transportation of the lubricating oil. In addition, compared with the splash lubrication solution, structures such as oil guide grooves or oil baffles can be reduced in the gearbox. Compared with the structure of splash lubrication set in the gearbox, the oil pipe structure 100 can have a higher degree of integration and a smaller volume, thereby reducing the volume of the gearbox.

[0087] In some embodiments, Figure 3 , Figure 5As shown, the gearbox includes a transmission assembly 60, and the transmission assembly 60 includes two adjacent transmission shafts, and at least one pipe body 10 in the oil pipe structure 100 passes through the area between the two adjacent transmission shafts. Therefore, the pipe body 10 can deliver lubricating oil to the area between the two transmission shafts, and by arranging a nozzle 43 on the pipe body 10, the lubricating oil can pass through the nozzle 43 to prevent the two transmission shafts from being lubricated, so as to achieve lubrication of the two transmission shafts.

[0088] In some embodiments, Figure 3 As shown, the transmission assembly 60 includes: a main shaft 61, a secondary shaft 62 and a differential 63. The main shaft 61 is provided with a primary driving gear, and the secondary shaft is provided with a primary driven gear and a secondary driving gear. The primary driven gear meshes with the primary driving gear, and the secondary driving gear meshes with the differential 63. Among them, the pipeline 1 passes through the area between the main shaft 61 and the secondary shaft 62, and the pipeline 1 is located radially outside the secondary driving gear. Figure 3 The tube 10 is shown passing through the area between the main shaft 61 and the secondary shaft 62)

[0089] Thus, the gap between the main shaft 61 and the secondary shaft 62 can be fully utilized to reduce the space occupied by the transmission assembly 60 and the oil pipe structure 100 as a whole, which is beneficial to reducing the overall volume of the gearbox.

[0090] In some embodiments, the first oil circuit and / or the second oil circuit constitute a motor cooling oil circuit, which can ensure the delivery of lubricating oil to the motor. In addition, when the pipeline 1 passes through the area between the main shaft 61 and the secondary shaft 62, the distance between the pipeline 1 and the motor is short. By setting a pipe column of the pipeline 1 to directly connect the motor cooling oil circuit, the length of the pipe column can be shortened, which is conducive to shortening the pipe body and the motor coolant oil circuit, thereby shortening the overall oil circuit in the gearbox, which is conducive to simplifying the gearbox structure and reducing processing costs.

[0091] Furthermore, if Figure 6 As shown, the gearbox includes a heat exchanger 53 fixedly arranged outside the box body 50, and the oil pipe structure 100 includes a first pipe body 101 and a second pipe body 102 that are interconnected and located in the same plane. A first pipe column 11 is fixedly arranged on the first pipe body 101, and the first pipe body 101 and the second pipe body 102 are connected through a second pipe column 12. A third pipe column 13 is fixedly arranged on the second pipe body 102.

[0092] The first pipe body 101 is connected to the heat exchanger 53 through the first external interface 14 on the first pipe column 11. The second pipe column 12 is connected to the first rear oil pipe 71 on the box body 50 through the first external interface 14. The second pipe body 102 is connected to the first front oil pipe 72 on the box body 50 through the third pipe column 13.

[0093] Thus, the lubricating oil can flow into the first pipe column 11 from the first external interface 14 after passing through the heat exchanger 53, so that the lubricating oil flows into the first pipe body 101 along the connecting groove in the first pipe column 11, and the lubricating oil in the first pipe body 101 flows along the flow channel to the second pipe body 102, and the lubricating oil in the second pipe body 102 can flow from the first external interface 14 to the first rear oil guide pipe 71 through the second pipe column 12, and can also flow into the first front oil guide pipe 72 through the third pipe column 13.

[0094] In some embodiments, Figure 4 As shown, the housing 50 includes a first oil guide branch, the first oil guide branch includes a first rear oil guide groove (not shown in the figure) connected to the first rear oil guide pipe 71, the first rear oil guide groove is connected to the second rear bearing chamber 81 where the second rear bearing is located; the second rear bearing chamber 81 is provided with a second rear oil guide groove 91 connected to the third rear bearing chamber 82.

[0095] Thus, the lubricating oil in the first rear oil guide pipe 71 can flow into the first rear oil guide groove, and then flow into the second rear bearing chamber 81 through the first rear oil guide groove to lubricate the second rear bearing in the second rear bearing chamber 81 .
