Connecting device between a hybrid electric vehicle and its motor and clutch

Abstract

The invention discloses a hybrid electric vehicle and a connecting device between a motor and a clutch thereof. The latter includes an outer bracket and an inner bracket detachably connected with the outer bracket. The outer bracket is a sleeve-type structure and is set and fixed on the motor In the inner hole of the rotor, the inner bracket is an annular plate-shaped structure, and its annular end surface is attached and fixed to the outer hub of the clutch. In this way, when the motor is matched with a clutch of a different specification, it is only necessary to replace the connecting device of a different specification without redesigning the motor or the clutch. Without changing the existing structure of the motor rotor and clutch, that is The reliable connection of the two can be realized, thereby reducing the design requirements of the parts and improving the generalization level of the clutch; at the same time, the inner bracket and the outer bracket adopt a detachable connection method, which improves the convenience of disassembly and assembly, and facilitates parts Replacement maintenance, improve assembly and maintenance efficiency, reduce production and maintenance costs.

Description

technical field [0001] The invention relates to the technical field of auxiliary components of a hybrid electric vehicle, in particular to a connection device used for a motor and a clutch of a new energy vehicle. The present invention also relates to a hybrid electric vehicle comprising the above connection device. Background technique [0002] With the continuous improvement of environmental protection awareness, hybrid technology is actively applied to automobile production, and the mutual supplement and mutual conversion of electric motor power and internal combustion engine power need to be realized by clutches. [0003] The traditional automotive powertrain includes an engine, clutch and gearbox. The power generated by the engine is transmitted to the gearbox through the clutch. When modifying the transmission powertrain, it is necessary to connect the newly added motor to the clutch. In the prior art, the outer hub of the clutch is directly connected to the rotor of ...

AI Technical Summary

Problems solved by technology

In the prior art, the outer hub of the clutch is directly connected to the rotor of the motor. However, this direct connection is only suitable for the simultaneous design and development of the clutch and the motor. The assembly accuracy of the motor rotor has high technical requirements for the outer hub of the clutch, and the general design of the clutch cannot be carried out, and the development and production costs are relatively high
