Description

Technical Field

[0001] This utility model relates to the field of engine cooling technology for motorcycles, and more particularly to a dual-clutch cooling system for motorcycles. Background Technology

[0002] Currently, mainstream dual-clutch cooling systems on the market use an oil circulation cooling mode, utilizing circulating oil within the engine casing to remove heat from the clutches, which is then cooled by coolant and airflow. However, existing dual-clutch arrangements (such as two clutches arranged side-by-side on one side or a large clutch housing a small clutch) have drawbacks: the heat from the two clutches is highly concentrated, especially in adjacent areas where the heat density is extremely high. Oil circulation cooling is insufficient to effectively remove this heat, easily leading to overheating of the clutches and even burning out the clutch plates. This not only interrupts normal vehicle operation but also significantly increases maintenance costs and frequency, substantially reducing the reliability and durability of the motorcycle. This severely limits the further development and application of dual-clutch technology in the motorcycle field, necessitating an innovative cooling system to solve this problem.

[0023] It also includes an oil spraying system 3 and an oil circulation system 4; the engine housing 1 is equipped with an oil spraying system 4 for spraying oil 3 onto the clutch, and the oil spraying system 3 is located directly above the clutch 2; the engine housing 1 is equipped with an oil circulation system 4 for the return of sprayed oil, and the oil circulation system 4 is connected to the oil spraying system 3; the bottom of the engine housing 1 is equipped with a bottom shell 102, and an oil storage chamber 10201 is provided between the bottom shell 102 and the engine housing 1; the bottom of the oil storage chamber 10201 is equipped with a pipeline for conveying oil in, and the pipeline is connected to an oil cooler; the oil spraying system 3 and the oil circulation system 4 are connected to the oil storage chamber.

[0024] The oil spraying system 3 includes an oil pump 301, a connecting pipe 302, and a spray nozzle 303. Two oil pumps 301 are symmetrically distributed on the left and right sides on the engine housing 1. Each of the two oil pumps 301 is connected to a connecting pipe 302, and the connecting pipe 302 is connected to the oil reservoir 10201 to draw oil from the oil reservoir 10201 into the oil pump 301. Each of the two oil pumps 301 is equipped with a spray nozzle 303 to spray the oil from the oil pump 301 onto the surface of the clutch 2.

[0025] The spray nozzle 303 is equipped with a diffuser for expanding the oil spray range, thereby improving the heat dissipation rate.

[0026] The oil circulation system 4 includes an oil outlet 402, an oil collection chamber 404, and an oil pipeline 405. An oil outlet 402 is located at the rear bottom of the engine housing 1, connected to a filter for filtering impurities in the oil, and the filter is connected to an oil cooler. An oil collection chamber 404 is located at the bottom inside the engine housing 1, directly below the clutch 2, and is connected to the oil outlet 402. An oil pipeline 405 is located inside the engine housing 1, connected to the oil outlet 402, for circulating oil between the engine housing 1 and the oil cooler. When flowing through the clutch 2 area, it can initially remove heat.

[0027] The oil circulation system 4 also includes an oil inlet 402 and an oil injector 403; the oil inlet 402 is provided at the bottom of the engine housing 1; several partition layers 1001 are provided inside the engine housing 1, and an oil injector 403 is provided in the arc-shaped center of the partition layer 1001. The oil injector 403 is connected to the oil inlet 402. A pump for delivering oil to the oil injector 403 is provided inside the oil inlet 402. The oil sprayed from the oil injector 403 will directly contact the engine crankshaft 101, thereby achieving heat dissipation of the engine crankshaft 101.

[0028] The partition layer 1001 is hollow, and the interior of the partition layer 1001 is connected to the oil inlet 402, so that the oil flows in the partition layer, thereby dissipating heat to the area outside the partition layer 1001.

[0030] First, the oil in the oil reservoir 10201 is drawn out by the oil pump 301 and sprayed onto the surface of the clutch 2 through the spray nozzle 303. The oil flowing over the surface of the clutch 2 continues to flow downward and then comes into contact with the engine crankshaft 101, the drive wheel 10101 and the crank 10102. The oil that comes into contact with the engine crankshaft 101 flows into the oil collection chamber 404 and is discharged through the oil outlet 4022 connected to the oil collection chamber 404. At this time, the impurities in the oil are filtered by the filter connected to the oil outlet 402. Then, the filtered oil is drawn into the oil cooler and cooled. The cooled oil is then returned to the oil reservoir 10201 and the above steps are repeated to dissipate heat from the clutch 2, the engine crankshaft 101, the drive wheel 10101 and the crank 10102.

[0031] Furthermore, the cooled oil inside the oil reservoir is pumped to the fuel injector through the pump inside the oil inlet. The oil sprayed from the fuel injector will then come into direct contact with the engine crankshaft, thus cooling the engine crankshaft. The cooling rate is increased through these two spraying methods.

[0032] The above technical solutions can reduce the probability of clutch burnout due to high temperature, reduce maintenance costs and frequency, reduce the clutch operating temperature to the optimal operating temperature, and reduce the burning failure rate, thereby improving the overall reliability and durability of the motorcycle and optimizing the user experience.
