Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] like figure 1 and figure 2 As shown, the device for connecting the engine and the motor of the present invention includes a friction member 3 and a pressing member 5 . Wherein, the engine and the motor are connected together through the friction member 3 . When the engine or the motor is working, the friction member 3 transmits torque to the engine and the motor. And when the torque of the engine or the motor is too large, the friction member 3 can slip between the engine, thereby reducing the damage to the crankshaft of the engine or the motor shaft 2 caused by the too large torque of the engine or the motor. The pressing member 5 is used to press the friction member 3 on the flywheel 1 of the engine, so as to realize the pressing between the friction member 3 and the engine.

[0029] In one embodiment, such as image 3 As shown, the friction member 3 includes...

Abstract

The invention relates to a device for connection of an engine and a motor and a hybrid electric vehicle. The device comprises a friction part which comprises a friction plate and a connection hole in the middle of the friction plate, a motor shaft is penetratingly arranged in the connection hole to be fixedly connected with the friction part, at least part of the friction plate is pressed onto a flywheel of the engine by a pressing part, and accordingly torques from the motor or the engine can be transferred to the engine or the motor. When the engine or the motor is overloaded, slipping exists between the friction part and the engine, and consequently a crankshaft of the engine or a motor shaft can be protected from damages caused by overloading.

Description

technical field [0001] The present invention relates to a torque transmission device for a gasoline-electric hybrid vehicle, in particular to a device for connecting an engine and a motor, and also to a gasoline-electric hybrid vehicle comprising the above-mentioned device. Background technique [0002] Gasoline-electric hybrid vehicles still occupy an important segment due to their high fuel economy and superior driving performance. A general hybrid vehicle includes an engine and an electric motor, and the engine is generally directly connected to the electric motor. [0003] Due to the working characteristics of new energy vehicles, such as the engine will start and stop frequently. Coupled with the uncontrollability of engine start-up and the unique vibration characteristics of the engine, it will cause shocks to motors with relatively stable working conditions and high controllability. Both the engine and the motor may run abnormally and cause overload. At the same tim...
