A power coupling device for a hybrid vehicle

Abstract

The invention discloses a dynamic coupling device used for a hybrid electric vehicle. The dynamic coupling device used for the hybrid electric vehicle comprises a one-way clutch and a self-aligning spline housing. The dynamic coupling device used for the hybrid electric vehicle is characterized in that the self-aligning spline housing is integrally arranged on the inner ring or the outer ring of the one-way clutch, the self-aligning spline housing is connected with a power-output shaft or a power-input shaft through a spline, and gaps exist between connected spline teeth, and tiny relative floating between the inner ring and the outer ring of the one-way clutch can occur, so that an automatic self-aligning function of a power-input end and a power-output end of the one-way clutch is achieved so as to meet requirements of concentricity of the power-input end and the power-output end, and the dynamic coupling device used for the hybrid electric vehicle solves the problems that the usability of the one-way clutch is reduced and service life of the one-way clutch is shortened due to the large eccentricity between the power-input end and the power-output end of the one-way clutch.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a power coupling device for a hybrid electric automobile. Background technique [0002] Currently, in single-motor parallel hybrid vehicles on the market, a part of the power coupling device uses a combination of a one-way clutch and a friction clutch for power coupling between the engine and the motor. In practical applications, the power input end and power output end of the one-way clutch (that is, the inner and outer rings of the one-way clutch) are required to have a high degree of concentricity, but due to the influence of processing, assembly and other factors, the one-way clutch There is a large eccentricity between the power input end and the power output end. [0003] In the prior art, the self-aligning spline sleeve and the power output end are integrated. In fact, neither the power input end nor the power output end of the one-way clutch has the funct...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides a power coupling device for a hybrid vehicle, which is used to make the power input end or power output end of the one-way clutch have a self-aligning function, thereby solving the power coupling between the engine and the motor, due to the one-way The power input end and power output end of the clutch are eccentrically caused by the degradation of the performance and life of the one-way clutch, etc.
