[0035] The specific embodiments of the utility model will be described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0036] The oil guide device and the vehicle according to the utility model are described below with reference to the drawings.

[0037] As Figure 1 shown, the oil guide device in the embodiment includes a booster pipeline 1, a booster assembly and an oil pipe assembly, the booster assembly includes a first booster component and a second booster component, the second booster component has an oil inlet end 223 for inputting lubricating oil, the oil pipe assembly includes a first lubricating oil pipe 31 and a second lubricating oil pipe 32 for outputting lubricating oil into a gearbox, and the inner diameter of the booster pipeline 1 is greater than the inner diameters of the first lubricating oil path and the second lubricating oil path. One end of the booster pipeline 1 is communicated with the first lubricating oil path through the first booster component, and the other end is communicated with the second lubricating oil path through the second booster component, so that the lubricating oil input by the oil inlet end 223 can flow into the booster pipeline 1 and the second lubricating oil pipe 32 respectively. In the embodiment, by providing the booster pipeline 1 with an inner diameter greater than the first lubricating oil path and the second lubricating oil path, the delivery pressure of the lubricating oil is improved, the lubricating oil amount demand of the subsequent oil path is met, the side of the first lubricating oil path can still maintain good delivery effect even if a plurality of oil pipes for outputting lubricating oil into the gearbox are arranged on the side, the technical problem of low delivery pressure of the lubricating oil of the oil guide device in the prior art is overcome, and the output effect of delivering hydraulic oil into the gearbox is improved. The lengths of the booster pipeline 1, the first lubricating oil pipe 31 and the second lubricating oil pipe 32 can be adjusted according to actual needs, so as to better adapt to the gearbox of large size.

[0038] As Figure 1As shown, in this embodiment, the first lubricating oil pipe 31 includes a main delivery pipe 311 and multiple branch pipes 312 disposed on the main delivery pipe 311. The ends of the main delivery pipe 311, the multiple branch pipes 312, and the second lubricating oil pipe 32 all have curved output sections 33. The bending direction of each curved output section 33 faces the inside of the gearbox, so that the lubricating oil can be smoothly output into the gearbox. In this embodiment, by providing multiple branch pipes 312 on the main delivery pipe 311, and having the multiple branch pipes 312 connected to different positions on the gearbox, the lubricating oil can be sprayed into the gearbox from different positions, achieving a better lubrication effect on the parts.

[0039] In this embodiment, the curvature of the curved output section 33 ranges from 80° to 150°. Preferably, the curvature of the curved output section 33 is set to 90°, which ensures that the lubricating oil in the pipeline can be smoothly delivered to the gearbox, while also reducing the footprint of the oil guiding device.

[0040] like Figure 1 As shown, each branch pipe 312, at the end opposite to the curved output section 33, is connected to the main delivery pipe 311 via a first oil pipe connector 211. In this embodiment, there are two branch pipes 312, spaced apart along the length of the main delivery pipe 311, to ensure sufficient lubricating oil is delivered to the gearbox. Each branch pipe 312 is arranged perpendicular to the main delivery pipe 311. Furthermore, in this embodiment, sufficient gaps are maintained between the multiple branch pipes 312, and the multiple pipelines for delivering lubricating oil are evenly distributed, facilitating maintenance. It should be noted that the first oil pipe connector 211 is a tee connector as used in the prior art, and the number of branch pipes 312 can be adjusted according to actual needs.

[0041] like Figure 2 As shown, in this embodiment, the second lubricating oil pipe 32 includes a first straight pipe section 321, a second straight pipe section 322, and a third straight pipe section 323 connected in sequence.

The first straight pipe section 321 is connected to the booster pipe 1 through a second booster component. A second bent section 325 is also connected between the second straight pipe section 322 and the third straight pipe section 323. The end of the third straight pipe section 323 facing away from the second straight pipe section 322 has a bent output section 33. The bending direction of the bent output section 33 faces the inside of the gearbox. The bending directions of the first bent section 324 and the second bent section 325 are both facing the gearbox, and the arc range is 80°-150°.

[0042] Preferably, in the embodiment, the first curved section 324 and the second curved section 325 are set to have an arc of 135°, and the curved output section 33 is set to have an arc of 90°, which not only ensures that the lubricating oil in the pipeline can be smoothly delivered into the gearbox, but also reduces the floor space occupied by the oil guide device.

[0043] As shown in the drawings, Figure 1 In the embodiment, the end of the curved output section 33 towards the gearbox is provided with an external connector 4 connected to the gearbox. The external connector 4 can be a connector with external threads, and the gearbox is provided with a plurality of interfaces with internal threads. The external connector 4 is inserted into the interface by thread cooperation, which ensures that the curved output section 33 is stably installed on the gearbox. The external threads of the external connector 4 and the gearbox are not shown in the drawings. Figure 1 The position of the interface on the gearbox can be adjusted according to actual needs. The interface is generally arranged in a position in the gearbox that is difficult to lubricate, so as to ensure the lubrication effect of the parts in the gearbox. Similarly, after the position of the interface is adjusted, the position of the external connector 4 is also adjusted to correspond to the position of the interface, so as to accurately lubricate the parts in the gearbox.

[0044] As shown in the drawings, Figure 1 In the embodiment, the first pressurizing component includes a threaded first oil pipe connector 211 and a first straight-through connector 212. The first straight-through connector 212 is arranged between the end of the pressurizing pipeline 1 and the first oil pipe connector 211. The second pressurizing component includes a threaded second oil pipe connector 221 and a second straight-through connector 222. The second straight-through connector 222 is arranged between the end of the pressurizing pipeline 1 and the second oil pipe connector 221. The first oil pipe connector 211 and the second oil pipe connector 221 each have three oil ports for connecting oil pipes. It should be noted that the first straight-through connector 212 and the second straight-through connector 222 can be straight-through connectors in the prior art.

[0045] In the embodiment, the inner diameter of the first lubricating oil pipe 31 and the second lubricating oil pipe 32 ranges from 5 mm to 15 mm, and the inner diameter of the pressurizing pipeline 1 ranges from 20 mm to 30 mm. Preferably, in an embodiment, the inner diameter of the first lubricating oil pipe 31 and the second lubricating oil pipe 32 is set to 10 mm, and the inner diameter of the pressurizing pipeline 1 is set to 25 mm. At this time, the delivery efficiency of the lubricating oil in the pipeline is relatively high, and the internal workpieces of the gearbox can be sufficiently lubricated.
