Abstract
A power assembly connecting device for a pure electric vehicle aims to solve the problem that the service lift of an electric motor bearing is influenced due to the additional radial force brought by the weight of a fly wheel and a clutch assembly and the additional radial force brought by the separation force of a clutch. The power assembly connecting device adopts the method that a fly wheel shaft, angular contact ball bearings mounted face to face and other components are added between an electric motor shaft and the fly wheel. The additional radial force brought by the weight of the fly wheel and the clutch assembly and the additional radial force brought by the separation force of the clutch are transmitted to a flywheel casing, so that the stress problem of the electric motor shaft is effectively solved.
Description
[technical field]
The invention belongs to the electric vehicle engineering field, relate to the power transmission between motor and the change speed gear box.
[background technology]
At present, in the pure electric sedan power system of having developed, motor output shaft is connected with flywheel and clutch assembly by spline both at home and abroad, and the weight of flywheel and clutch assembly acts directly on the motor output shaft; After chaufeur is stepped on clutch pedal, the axial separation force of power-transfer clutch also by flywheel action on motor output shaft.Because the constructional feature of electrical motor self, motor output shaft only can bear torsion and underloading diametral load.If bearing extra radially or axial force very easily influences the electrical motor working stability, shorten its service life.
[summary of the invention]
The invention provides a kind of simple and reliable connection structure, solved the problem that additional axial force that additional radial pressure that motor reel brings because of the weight of bearing flywheel and clutch assembly and disengaging of clutch power brings influences life-span and stability.
The technical solution adopted for the present invention to solve the technical problems is: increase clutch bell between gear box casing and electrical motor, electrical motor is connected with gear box casing by clutch bell; Flywheel shaft, angular contact ball bearing, axle sleeve, spindle nose, end cap, flywheel are installed in the flywheel shell, wherein flywheel shaft is connected by spline with motor reel, a pair of angular contact ball bearing is installed face-to-face, axially connect by axle sleeve between the angular contact ball bearing, the angular contact ball bearing outside is spacing by little circular nut, circular nut stop washer, end cap and the flywheel shaft shaft shoulder respectively; Motor reel is connected with clutch bell by the angular contact ball bearing of flywheel shaft and installation face-to-face, and the weight of clutch bell and clutch assembly is delivered on the clutch bell by flywheel shaft-angular contact ball bearing; The additional axial force that disengaging of clutch power is brought also is delivered on the clutch bell by flywheel-flywheel shaft-angular contact ball bearing.
Beneficial effect of the present invention: simple in structure, technical risk is low, efficiently solves the problem that additional axial force that additional radial pressure that motor reel brings because of the weight of bearing flywheel and clutch assembly and disengaging of clutch power brings influences life-span and stability.
[description of drawings]
The present invention is further described below in conjunction with drawings and Examples.

Diagram part explanation: 1, little circular nut; 2, circular nut stop washer; 3, clutch bell; 4, axle sleeve; 5, end cap; 6, hexagon bolt with flange; 7, spindle nose; 8, flywheel shaft; 9, angular contact ball bearing; 10, hex bolt, spring washer peace washer sets component; 11, flywheel; 12, electrical motor; 13, motor reel.
[specific embodiment]
The present invention mainly is made of clutch bell 3, axle sleeve 4, end cap 5, spindle nose 7, flywheel shaft 8, angular contact ball bearing 9, flywheel 11 etc.
End cap 5 is enclosed within on the flywheel shaft 8, spindle nose 7, angular contact ball bearing 9, axle sleeve 4 are placed on the flywheel shaft 8, circular nut is installed with stop washer 2, screw roundlet nut 1, the assembly that above part is formed places on the clutch bell 3, and end cap 5 is fixed on the clutch bell 3; The assembly that above part is formed is installed on the electrical motor 12; Clutch driven disc and flywheel 11 are installed on the flywheel shaft 8; Change speed gear box is connected on the clutch bell 3.
Clutch bell 3 is base paries of the present invention, connects motor field frame and gear box casing, is the installation basis of miscellaneous part of the present invention.
Flywheel shaft 8 is critical partss of the present invention, and during mode of operation, the weight of flywheel 11 and clutch assembly is delivered on the clutch bell 3 by flywheel shaft 8 and angular contact ball bearing 9, has eliminated the influence of this diametral load to motor reel.
During the chaufeur let slip the clutch, the separating force of power-transfer clutch is delivered on the clutch bell 3 by flywheel 11-flywheel shaft 8-angular contact ball bearing 9, thereby has eliminated the influence of this axial force to motor reel.
