Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to a heat dissipation housing of a motorcycle gearbox. Background Art

[0002] During the operation of a motorcycle gearbox, the friction of the speed gears inside the box will cause the temperature inside the gearbox to continue to rise, resulting in a decrease in the lubrication effect and viscosity of the gear oil. In order to protect the gearbox from damage and keep the gearbox within the appropriate temperature range, the gearbox needs to be cooled.

[0003] However, currently, when dissipating the heat of the gearbox, the gearbox oil is usually introduced into the radiator and the heat is dissipated by air cooling. However, the heat dissipation effect of only blowing air is poor. Even after the heat is dissipated by the radiator, a certain amount of heat may still remain on the surface of the gearbox. In addition, due to the limited space of the motorcycle, the gearbox is usually installed on the left and right side covers of the engine. When a person is riding, if the operating temperature of the gearbox is too high, once the driver's legs touch the gearbox housing, it may cause safety hazards such as burns.

[0004] Therefore, we propose a motorcycle gearbox heat dissipation housing to solve the above problems. Utility Model Content

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment provides a motorcycle gearbox heat dissipation housing, including a housing body 1, a water cooling component and an anti-scalding component 3, the housing body 1 includes an upper housing 11 and a lower housing 12, a partition 13 is provided inside the lower housing 12, the partition 13 divides the lower housing 12 into a cooling chamber 14 for containing coolant below the partition 13 and a working chamber 15 for containing a gear mechanism above the partition 13, the water cooling component includes a water inlet pipe 2 and a water outlet pipe 21 connected to the working chamber 15, a pump body 23 is provided on the cooling pipe 22, and the cooling pipe 22 runs through the cooling chamber 14, the anti-scalding component 3 is located on both sides of the housing body 1, the two ends of the anti-scalding component 3 are integrally connected with the outer wall of the housing body 1, and a gap is left between the anti-scalding component 3 and the outer wall of the housing body 1;

[0025] Specifically, when the pump body 23 is started, the gear oil in the working chamber 15 is pumped to the cooling pipe 22 through the water outlet pipe 21. After the gear oil in the cooling pipe 22 flows through the cooling chamber 14, it is cooled by the coolant in the cooling chamber 14, and then it is re-delivered to the working chamber 15 through the water inlet pipe 2. The cycle is repeated to cool the gear oil, reduce the heat of the shell body 1, and improve the working efficiency of the gear mechanism inside the shell body 1. When people ride on a motorcycle, the anti-scalding part 3 is used to prevent the driver's legs from directly contacting the two sides of the shell body 1, thereby avoiding burns. In addition, by arranging an independent cooling chamber 14 inside the lower cover 12, the gear box mechanism can be provided with heat dissipation protection separately, so that the heat dissipation system of the gear box can operate independently, which is more convenient during inspection and maintenance, so that the heat dissipation problem of the gear box can be dealt with in a targeted manner.

[0026] Preferably, an oil discharge pipe 4 is provided in the middle of the partition 13, and the oil discharge pipe 4 is used to discharge the gear oil in the shell body 1. The oil discharge pipe 4 passes through the cooling chamber 14 and extends to the outside of the lower cover 12. The output end of the oil discharge pipe 4 is connected to the oil discharge bolt 41. When the oil discharge bolt 41 is opened, the gear oil is discharged through the oil discharge pipe 4, and the portion of the oil discharge pipe 4 located in the cooling chamber 14 is spiral, which can increase the contact time of the gear oil with the coolant in the cooling chamber 14 when it is discharged, thereby improving the cooling effect on the gear oil and avoiding burns to the operator when the gear oil is discharged.

[0027] Preferably, guide parts 5 are provided at both ends of the partition 13, and the height of the guide parts 5 gradually decreases toward the input end of the oil unloading pipe 4, so that the gear oil in the working chamber 15 can be guided toward the input end of the oil unloading pipe 4, so that the gear oil can be discharged more thoroughly.

[0028] Preferably, a first cooling fin 6 is provided at the bottom of the lower cover shell 12, and a second cooling fin 61 is provided on the outer wall of the upper cover shell 11 and the lower cover shell 12 close to the anti-scalding part 3. When the vehicle is driving, the wind force increases and blows toward the first cooling fin 6 and the second cooling fin 61, which can dissipate the heat on the shell body 1, which helps to improve the heat dissipation efficiency of the shell body 1, and one end of the second cooling fin 61 does not contact the anti-scalding part 3, thereby preventing the second cooling fin 61 from transferring the heat on the shell body 1 to the anti-scalding part 3.

[0029] Preferably, a fixing plate 7 is connected to the side of the anti-scalding component 3 away from the shell body 1, and the fixing plate 7 can be integrally connected with the anti-scalding component 3 to improve the connection strength, and the anti-scalding component 3 connected to the upper cover shell 11 and the anti-scalding component 3 connected to the lower cover shell 12 are detachably connected by fixing bolts 71. When the upper cover shell 11 is connected to the lower cover shell 12, the upper cover shell 11 and the lower cover shell 12 are connected by the fixing bolts 71 to form the shell body 1.

[0030] Preferably, the portion of the cooling pipe 22 located in the cooling chamber 14 is composed of multiple "S"-shaped connecting pipes connected end to end, which can increase the overall length of the cooling pipe 22, thereby increasing the residence time of the gear oil in the cooling chamber 14 and further improving the cooling effect of the gear oil.

[0031] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
