Hybrid electric vehicle and connecting device between motor and clutch of hybrid electric vehicle

Abstract

The invention discloses a hybrid electric vehicle and a connecting device between a motor and a clutch of the hybrid electric vehicle. The connecting device comprises an outer support and an inner support detachably connected with the outer support. The outer support is of a sleeve type structure and is fixed into an inner hole of a motor rotor in a sleeved mode. The inner support is of a circular ring type plate like structure. The annular end face of the inner support is attached and fixed to an outer hub of the clutch. In this way, when the motor is matched with clutches of different specifications, only the connecting device needs to be replaced with connecting devices of different specifications, the motor or the clutch does not need to be redesigned, and the motor and the clutch are reliably connected on the premise that existing structures of the motor rotor and the clutch are not changed, so that the design requirement for parts is lowered, and the universalization level of the clutch is improved; meanwhile, the inner support and the outer support are detachably connected, the disassembly and assembly convenience is improved, replacement and maintenance of the parts are facilitated, the assembly and maintenance efficiency is improved, and the production and maintenance cost is lowered.

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
