Normally-disengaged clutch integrated in motor rotor bracket and vehicle comprising same

Abstract

The invention provides a normally-disengaged clutch integrated in a motor rotor bracket. The normally-disengaged clutch comprises a first pressure disk, a driven disk, a second pressure disk and diaphragm springs which are sequentially and adjacently arranged, wherein the first pressure disk, the second pressure disk and the diaphragm springs are assembled on the motor rotor bracket; the driven disk is assembled on the main shaft of a transmission system and is positioned between the first pressure disk and the second pressure disk; the diaphragm springs do not exert a pressing force on the first pressure disk and the second pressure disk at a normal state, and the first pressure disk and the second pressure disk do not press the driven disk; and when the diaphragm springs are acted by a driving force, the first pressure disk and the second pressure disk can press the driven disk. As the first pressure disk, the second pressure disk and the diaphragm springs of the normally-disengaged clutch are all mounted on the motor rotor bracket, the defects of low level of integration and large space occupation of clutches in the prior art are overcome.

Description

【Technical field】 [0001] The invention relates to a clutch. In particular, the present invention relates to a normally open clutch integrated in the rotor bracket of an electric machine and a vehicle comprising the same. 【Background technique】 [0002] For a vehicle, a clutch is a device arranged between the engine and / or the motor and the drive train, and is used to cut off and connect the power from the engine and / or the motor to the drive train. When starting, the clutch allows the engine and / or motor to be smoothly combined with the transmission system, making the vehicle start smoothly; when shifting gears, the clutch allows the engine and / or motor to be separated from the transmission system quickly, reducing the impact between the gears in the transmission, thereby achieving smooth shifting. When the vehicle is running, when the vehicle is under excessive load, the clutch will slip to prevent the drive train from being overloaded. [0003] For vehicles that include ...
