Description
Technical Field
The utility model belongs to a derailleur cooling water channel structure specifically relates to a wet-type double clutch derailleur integrated form cooling water channel structure.
Background
The double clutch is a very critical and important component of the double clutch transmission, and realizes power transmission through friction force between a friction plate and a dual steel sheet. When the friction plate and the dual steel plate of the double clutch are gradually combined and synchronously run, sliding friction occurs between the friction plate and the dual steel plate due to different rotating speeds of the friction plate and the dual steel plate, and a large amount of friction heat is generated. If the heat cannot be dissipated in time, the high-temperature environment in the double clutch can cause the friction plate to fail, and further cause the double-clutch transmission to fail. Therefore, the double clutch must be cooled.
At present, the double clutches are divided into a dry double clutch and a wet double clutch. The dry-type double clutch mainly radiates heat by air, and the wet-type double clutch mainly radiates heat by oil. Meanwhile, in order to achieve a better heat dissipation effect, a cooling liquid heat dissipation mode is adopted in the existing wet type dual-clutch transmission. The existing cooling liquid heat dissipation modes mainly comprise a water channel integrated type mode, an external heat exchanger type mode and an internal cooling pipe type mode.
The water channel integration type is that an integrated cooling water channel is arranged on the transmission shell, and the heat dissipation is realized by connecting the inlet and the outlet of the cooling water channel with the cooling pipe assembly. Specifically, heat generated by friction of friction plates in the double clutch can be transferred to a transmission shell through oil, the transmission shell transfers the heat to cooling liquid in a cooling water channel, and the cooling liquid absorbs the heat and then enters a cooling cycle of an engine through a cooling pipe assembly, and finally the heat is dissipated through a radiator. However, since the transmission casing itself needs to support the transmission shafting, and the cooling oil duct is integrally formed, the structure is already complicated, if the cooling water duct is also integrally formed, the structure of the transmission casing becomes more complicated, the difficulty of the casting process is greatly increased, and the casting defect is easily caused, so that the cooling liquid in the cooling water duct permeates into the oil cavity through the defects, the oil is failed, and further the failure of the parts in the transmission is caused. In order to avoid the coolant in the cooling water channel from entering the oil cavity, the transmission housing is 100% impregnated in the prior art, but the impregnation cost is high, and the above problems cannot be economically and practically solved.
The external heat exchanger is a heat exchanger which is specially arranged outside a transmission shell, oil in a transmission and cooling liquid in an engine cooling system are connected to the heat exchanger, and heat dissipation is realized in a heat exchange mode in the heat exchanger. If disclose a motor transmission cooling device and disclose a derailleur cooling mechanism and derailleur and vehicle in chinese utility model patent CN206723423U in chinese utility model patent CN202251889U, they all adopt to set up special external heat exchanger, and the radiating mode not only need set up the oil duct and draws forth the oil in the derailleur like this, and the cost of manufacture is high, and the oil of drawing forth is not the oil of maximum temperature state moreover, and the radiating efficiency is low.
The built-in cooling pipe type is characterized in that a built-in cooling pipe is arranged, cooling liquid is guided into the transmission, and heat dissipation is achieved in the transmission through heat exchange with the oil liquid. For example, the chinese utility model patent CN207316051U discloses a built-in cooling system of a wet-type dual-clutch automatic transmission, which needs to be provided with a special built-in cooling pipe, and has relatively complicated installation and relatively high manufacturing cost.
