Description

Technical Field

[0001] The utility model relates to the technical field of dry double clutches, in particular to a dry double clutch used in a transmission system. Background Art

[0002] Dual clutch is mainly used in dual clutch transmission, which is different from the general automatic transmission system. It is based on manual transmission but belongs to automatic transmission. In addition to the flexibility of manual transmission and the comfort of automatic transmission, it can also provide uninterrupted power output. At present, dual clutch is mainly divided into dry type and dry type.

[0003] The advantages of dry dual-clutch: fast acceleration, sufficient power, low energy loss, smooth shifting, and high transmission efficiency. Because the clutch plate of the dry dual-clutch transmission is not immersed in the transmission oil, the heat dissipation performance of this transmission is relatively poor, so the dry dual-clutch transmission is prone to overheating. The existing cooling methods for dry dual-clutch are relatively simple, and generally use wind to dissipate heat and cool down. However, the cooling method of the dry dual-clutch is only achieved by internal air cooling. When the internal temperature of the dry dual-clutch is high, the dry dual-clutch cannot achieve rapid internal cooling, which will make the cooling of the dry dual-clutch weaker when used for a long time, thereby affecting the service life of the dry dual-clutch and reducing the practicality of the dry dual-clutch.

[0047] Furthermore, six L-shaped mounting blocks 5 are fixedly connected to the inner walls of the two first fixing rings 2;

[0048] Among them, the corresponding three L-shaped mounting blocks 5 are arranged in a central array;

[0049] Among them, the L-shaped mounting block 5 is in an L shape;

[0050] A plurality of positioning holes 3 are formed on the upper surfaces of the first fixing ring 2 and the first rubber ring 4 , and the positioning holes 3 extend from the lower surfaces of the first fixing ring 2 and the first rubber ring 4 .

[0054] Furthermore, the two first connecting pipes 10 are fixedly connected to any two L-shaped mounting blocks 5;

[0055] The two opposite ends of the two heat dissipation pipes 6 are fixedly connected to the two first connecting pipes 10, and the heat dissipation pipes 6 are communicated with the interiors of the corresponding first connecting pipes 10;

[0056] Among them, two buffer rubber rings 9 are arranged on both sides of the upper side of the dry dual clutch body 1;

[0057] The adjacent outer surfaces of the two buffer rubber rings 9 are in contact with the upper and lower outer surfaces of the dry dual clutch body 1;

[0058] The outer surfaces of the two buffer rubber rings 9 on both sides facing each other are in contact with the outer surfaces of the two second fixing rings 8 on both sides adjacent to each other.

[0059] Wherein, the heat dissipation pipe 6 is arranged in a spiral;

[0060] The liquid storage tank 11 is provided on one side of the dry dual clutch body 1 , and the second connecting pipe 13 is fixedly connected to the upper surface of the liquid storage tank 11 ;

[0061] The graphite heat sink 12 is arranged on the outer surface of the liquid storage tank 11 .

[0062] Furthermore, a pump is provided in the liquid storage tank 11, the lower end of the second connecting pipe 13 is fixedly inserted into the liquid storage tank 11, and the output end of the pump is fixedly connected to the second connecting pipe 13;

[0066] Furthermore, when in use, the two first fixing rings 2 are aligned by means of the matching bolt positioning bolts 7. During this process, the two second fixing rings 8 are driven to squeeze the upper and lower outer surfaces of the dry dual clutch body 1 through the two buffer rubber rings 9. In addition, the first rubber ring 4 is also squeezed during the process of tightening the positioning bolts 7. Then, when the positioning bolts 7 are tightened, the two second fixing rings 8 are squeezed and fixed on the dry dual clutch body 1, which is convenient for disassembly and quick for installation.

[0067] As mentioned above, during installation, the liquid storage tank 11 can be installed in a position away from the dry dual clutch body 1 and at a lower temperature. Because the pump is provided with coolant, the second connecting pipe 13, the first connecting pipe 10, the circulation pipe 14 and the hose are also provided with coolant, and the heat dissipation pipe 6 is made of a high heat dissipation material, so when the pump is started, the pump transfers the coolant in the liquid storage tank 11 to the second connecting pipe 13, the hose, the first connecting pipe 10 and the heat dissipation pipe 6, and transfers the coolant in the second connecting pipe 13, the hose, the first connecting pipe 10 and the heat dissipation pipe 6 to the liquid storage tank 11, thereby transferring and circulating the coolant. In this process, the heat dissipation pipe 6 can take away the high temperature of the dry dual clutch body 1, and then conduct the external low temperature to the outside of the dry dual clutch body 1, thereby accelerating the heat dissipation and cooling of the dry dual clutch body 1;

[0068] Furthermore, in this solution, a temperature sensor 1 and a controller are provided on the liquid storage tank 11, and a temperature sensor 2 is provided on the dry dual clutch body. The controller is electrically connected to the pump, and the controller is electrically connected to both temperature sensor 2 and temperature sensor 1. When the temperature detected by temperature sensor 2 exceeds a certain threshold value of temperature sensor 1, the controller will control the start-up of the pump, thereby achieving automatic cooling and heat dissipation of the dry dual clutch body 1 when the temperature of the dry dual clutch body 1 is high, and the heat dissipation and cooling effect is good, thereby ensuring the stability of the dry dual clutch transmission, improving the service life of the dry dual clutch, and thus improving the practicality of the dry dual clutch.

[0069] Furthermore, the graphite heat sink 12 can enhance the heat dissipation effect of the dry dual clutch body 1 .

[0070] Working principle: When the device is used, the two first fixing rings 2 are aligned by using the matching bolt positioning bolts 7. In this process, the two second fixing rings 8 are driven to squeeze the upper and lower outer surfaces of the dry dual clutch body 1 through the two buffer rubber rings 9. In the process of tightening the positioning bolts 7, the first rubber ring 4 is also squeezed. Then, when the positioning bolts 7 are tightened, the two second fixing rings 8 are squeezed and fixed on the dry dual clutch body 1, which is easy to disassemble and quick to install.

[0071] As mentioned above, during installation, the liquid storage tank 11 can be installed in a position away from the dry dual clutch body 1 and at a lower temperature. Because the pump is provided with coolant, the second connecting pipe 13, the first connecting pipe 10, the circulation pipe 14 and the hose are also provided with coolant, and the heat dissipation pipe 6 is made of a high heat dissipation material, so when the pump is started, the pump transfers the coolant in the liquid storage tank 11 to the second connecting pipe 13, the hose, the first connecting pipe 10 and the heat dissipation pipe 6, and transfers the coolant in the second connecting pipe 13, the hose, the first connecting pipe 10 and the heat dissipation pipe 6 to the liquid storage tank 11, thereby transferring and circulating the coolant. In this process, the heat dissipation pipe 6 can take away the high temperature of the dry dual clutch body 1, and then conduct the external low temperature to the outside of the dry dual clutch body 1, thereby accelerating the heat dissipation and cooling of the dry dual clutch body 1;

[0072] Furthermore, in this solution, a temperature sensor 1 and a controller are provided on the liquid storage tank 11, and a temperature sensor 2 is provided on the dry dual clutch body. The controller is electrically connected to the pump, and the controller is electrically connected to both temperature sensor 2 and temperature sensor 1. When the temperature detected by temperature sensor 2 exceeds a certain threshold value of temperature sensor 1, the controller will control the start-up of the pump, thereby achieving automatic cooling and heat dissipation of the dry dual clutch body 1 when the temperature of the dry dual clutch body 1 is high, and the heat dissipation and cooling effect is good, thereby ensuring the stability of the dry dual clutch transmission, improving the service life of the dry dual clutch, and thus improving the practicality of the dry dual clutch.
