Problems solved by technology

For the connection between the engine and the motor / generator, there are mainly the following types at present. The first method is to install a traditional vehicle friction plate and clutch pressure plate system between the engine and the motor / generator. The automotive clutch system parts can realize power buffering between the engine and the motor / generator, and the performance is reliable, but the connection method is heavy and the axial space is large
The second connection method is to set a flexible coupling between the engine shaft and the motor / generator shaft. This structure has a small mass, but has a large axial dimension and requires high installation and centering.
The third structure is a rigid connection between the engine shaft and the motor / generator shaft. Since there is no flexible transition between the engine and the motor / generator, this structure has large vibrations and is likely to cause overload damage to the transmission system.

Embodiment Construction

[0008] This embodiment is used to illustrate the technical solution of the present invention, and the present invention is not limited to the following protection content.

[0009] As shown in FIG. 1 , the crankshaft 2 of the engine 1 is connected with the flywheel 5 through bolts. The flywheel 5 is located in the flywheel housing 4 . Flywheel 5 disk surface is in contact with friction plate 6. The friction plate 6 is in contact with the pressing plate body 7 . The pressing plate body 7 and the pressing plate cover 10 are snap-connected, and a diaphragm spring 9 is arranged between the pressing plate body 7 and the pressing plate cover 10 . The pressure plate cover 10 is connected with the flywheel 5 through bolts 8 . The friction plate 6 is connected with the motor / generator shaft 11 through its internal spline, the crankshaft 2 is provided with a supporting bearing 3, and the end of the motor / generator shaft 11 is connected with the supporting bearing 3. According to the...

Abstract

A device used for connecting vehicle engine to motor / generator is prepared for connecting flywheel to crankshaft of engine, arranging flywheel in flywheel shell, contacting flywheel disc surface to friction plate being contacted with body of press-plate, connecting press-plate body to fastener of press-plate cover, setting diaphragm spring between said body and said cover, arranging bolt holes on periphery of said cover and bolt holes on periphery of flywheel, using bolts to connect bolt holes on flywheel and said cover then connecting integral key of friction plate to shaft of motor / generator.

Description

technical field [0001] The invention belongs to a device in a power assembly of a hybrid vehicle, in particular to a connection device between an engine and a motor / generator of a hybrid vehicle. Background technique [0002] In hybrid vehicles, the powertrain type in which the engine is directly connected to the motor / generator is used in various types of vehicles. In this powertrain, the motor / generator is powered by the engine, and the The generator starts quickly, and the motor / generator drives the engine to start. For the connection between the engine and the motor / generator, there are mainly the following types at present. The first method is to install a traditional vehicle friction plate and clutch pressure plate system between the engine and the motor / generator. The advanced automotive clutch system parts can realize power buffering between the engine and the motor / generator, and the performance is reliable, but the connection method is heavy and the axial space is...
