Embodiment Construction

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

[0009] figure 1 A schematic diagram of the structure and cooling air flow direction of the present invention is given. The clutch housing 2 is provided with an exhaust port 5 and an air intake port 11, and the clutch housing 2 is provided with a dust cover 6 outside the exhaust port 5 to prevent Dirt and dust enter. A motor-driven blower 12 is installed at the intake port 11 of the clutch housing 2, and a cooling air duct 10 is installed at the intake port 11 in the clutch housing 2. The blower 12 is driven by the automobile power supply and blows out the cooling air From the outlet of the guide tube 10 to the middle part of the clutch, and passing through the first clutch diaphragm spring 15 and the second clutch diaphragm spring 16, a part of the cooling air passes through the back of the second clutch pressure plate 8 and the pressure plate and the second The gap betwe...

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 dual-clutch cooling device, in particular to an air cooling device of a dry-type dual-clutch in an automobile dual-clutch automatic transmission. Background technique: [0002] Automotive dual-clutch automatic transmissions (DCT) usually use two clutches (dual clutches). The gears of the transmission are arranged in odd and even numbers and connected to the two clutches respectively. When working, two gears can be selected at the same time to be in meshing state. Gears work and wait for another gear, and the gear shifting process is completed by alternate switching of the two clutches. DCT integrates the advantages of electronically controlled mechanical automatic transmission (AMT) and hydro-mechanical automatic transmission (AT), inherits many advantages of manual transmission, such as high transmission efficiency, compact installation space, light weight, and low price, and realizes uninterrupted power con...
