[0016] The embodiments of the utility model are described in detail below.

[0017] The embodiment provides a kind of double clutch electronic machine oil lubricating system, as shown in Figure 1 And Figure 2 It shows, including engine case 5, double clutch system is arranged in engine case 5, double clutch system includes first clutch 4, second clutch 4 and shift gear set, first clutch 4 and second clutch 4 are symmetrically arranged in the left and right sides of engine case 5, and shift gear set is arranged between first clutch 4 and second clutch 4.

[0018] Oil injection pump 1 is set on engine case 5 corresponding to first clutch 4 and second clutch 4 respectively, and the oil injection pump 1 is an electronic oil injection pump 1, whether oil injection is controlled by controller. The structure and working principle of electronic oil injection pump 1 are well known, which will not be described here. The bottom of engine is oil pan, which is used to store the returned oil. The oil inlet of oil injection pump 1 is connected to the oil pan of engine through oil inlet pipe 3, and the oil in oil pan is pumped out to be used as the lubricating oil of clutch 4. The oil outlet of injection nozzle 2 of oil injection pump 1 is located in engine case 5 and is aligned with the gap of clutch plate of corresponding clutch 4, so that the filtered lubricating oil enters oil injection pump 1 from oil injection pump 1 oil inlet pipe and enters the gap of clutch plate through injection nozzle 2, and the lubricating oil can be applied to the corresponding clutch 4 by oil injection pump 1.

[0019] The controller is used for controlling the oil injection pump 1 corresponding to the clutch 4 to inject oil into the clutch 4 during the operation of the clutch 4. Specifically, the controller is used for controlling the oil injection pump 1 corresponding to the clutch 4 to inject oil when the clutch 4 is in the separated state. Thus, the clutch 4 can be fully lubricated before being combined, and the heat generated by the friction of the clutch plate can be maximally transferred to the lubricating oil, so that the service life of the clutch 4 is prolonged.

[0020] The electronic oil lubrication system of the clutch of the embodiment is used in a two-wheeled motorcycle. The state of the clutch 4 can be acquired in real time. In a specific embodiment, a detection device for detecting whether the clutch 4 is in the engaged state or the separated state is provided, and the detection device is connected to the controller. The controller is used for controlling the oil injection pump 1 corresponding to the clutch 4 to inject oil when the clutch 4 is in the separated state. In some embodiments, the detection device can directly detect the state of the clutch 4, for example, by detecting the current gear and the gear shifting operation to determine the state of the clutch 4. In other embodiments, the detection device can determine the state of the clutch 4 by detecting the operation of the operating rod for gear shifting. The controller can be the controller of the two-wheeled motorcycle, and the oil injection pump 1 is controlled to work based on the electrical signal.

[0021] The oil injection pump 1 is detachably fixed on the engine case 5. The oil injection pump 1 and the oil inlet pipe 3 are located outside the engine case 5. The engine case 5 is provided with an opening for the oil injection nozzle 2 of the oil injection pump 1 to extend into. In this way, the oil injection pump 1 and the oil inlet pipe 3 are arranged outside, and no space in the engine case 5 is occupied, so that the maintenance is facilitated. Only a structure for fixing the oil injection pump 1 needs to be arranged on the engine case 5. In a specific embodiment, the structure for fixing the oil injection pump 1 on the engine case 5 is arranged according to the structure of the oil injection pump 1 used. For example, the engine case 5 is provided with a fixing seat matched with the shape of the pump body of the oil injection pump 1, or the oil injection pump 1 is provided with a threaded connection part, and the engine case 5 is provided with a corresponding threaded connection hole.

[0022] In a preferred embodiment, the oil injection nozzle 2 of the oil injection pump 1 is located directly above the corresponding clutch 4. Thus, the lubricating oil sprayed through the oil injection nozzle 2 enters the clutch plate gap from the top, and the coverage of the lubricating oil is relatively higher.

[0023] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
