Embodiment Construction

[0008] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0009] Fig. 1 has provided the structure of the present invention and the schematic diagram of the flow of cooling air, on the clutch housing 2 an air outlet 5 and an air inlet 11 are arranged, and on the clutch housing 2 the outside of the air outlet 5 is provided with a dust cover 6 , to prevent dirt and dust from entering. A motor-driven blower 12 is installed at the position of the air inlet 11 on the clutch housing 2, and a cooling air guide pipe 10 is installed at the position of the air inlet 11 in the clutch housing 2. The blower 12 is driven by the automobile power supply, and the cooling air blown out From the outlet of the guide tube 10 to the middle part of the clutch, and through the first clutch diaphragm spring 15 and the second clutch diaphragm spring 16, part of the cooling air passes through the back of the second clutch pressure plate 8 and the pres...

Abstract

The invention relates to a vehicle drying dual-clutch cooler, wherein said invention arranges gas inlet (11) and gas outlet (5) on the frame of dual-clutch automatic speed changer; mounts blower fan (12) driven by motor on the gas inlet (11); arranges divert tube (10) inside the frame (2) of speed changer; arranges axial ventilate holes on the flywheel disc (1) and clutch cover (9), to form the air refrigerating system. The invention can use cooling air to cool the clutch, to reduce its working temperature, while high working temperature will affect the service life and working property of drying dual-clutch.

Description

Technical field: [0001] The invention relates to an automobile dry-type double-clutch cooling device, in particular to an air cooling device for a dry-type double-clutch in an automobile double-clutch automatic transmission. Background technique: [0002] Automobile dual-clutch automatic transmission (DCT) usually uses two clutches (dual clutches). The transmission gears are arranged separately according to odd and even numbers, and are respectively connected to the two clutches. One gear works and the other gear waits, and the gear shifting process is completed through the alternate switching of the two clutches. DCT combines the advantages of electromechanical automatic transmission (AMT) and hydromechanical automatic transmission (AT), and inherits many advantages of manual transmission, such as high transmission efficiency, compact installation space, light weight, and low price, and realizes uninterrupted power transmission. It not only ensures the acceleration of the ...
