Abstract
It is used for the powerdriven spline structure of pure electric vehicle the utility model discloses one kind, including external splines and transition sleeve, described external splines is installed in the internal spline of transition sleeve, and there is the utility model external splines axial location to fix, intensity is high and the characteristics of being difficult play.
Description
Technical field
The utility model belongs to power transmission connecting mechanism technical field, is used for pure electric vehicle power more particularly, to one kind
The spline structure of transmission.
Background technology
To alleviate environmental problem, exhaust emissions is reduced, government greatly develops new-energy automobile in recent years, and motor is new energy
The power resources of automobile, the power transmission of motor uses spline structure, spline structure require external splines axial location fix,
Intensity is high, be difficult play.In terms of the powerdriven spline structure of pure electric vehicle, existing external splines does not have groove structure, directly
Tipping is fitted between motor and transition sleeve, and this structure is difficult to ensure that external splines axial location, easily produces axial float, or
The groove for installing jump ring is processed at axle two ends, causes processing technology complicated, the intensity of assembling difficulty and influence splined shaft.
The content of the invention
The purpose of this utility model is that designing one kind is used for the powerdriven spline structure of pure electric vehicle, can make external splines
Axial location is fixed, intensity high and is difficult play.
The purpose of this utility model is achieved in that a kind of for the powerdriven spline structure of pure electric vehicle, its spy
Point is that the structure includes external splines and transition sleeve, and described external splines is installed in the internal spline of transition sleeve.
Can be that described external splines is provided with and axle-steel silk back-up ring to further realize the purpose of this utility model
The groove of cooperation, axle-steel silk back-up ring is installed in a groove, and the internal spline of described transition sleeve is provided with and axle-steel silk back-up ring
The inner groovy of cooperation, external splines is installed in the internal spline of transition sleeve by axle-steel silk back-up ring.
Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model is to be used to move
The spline structure of power transmission, the external splines of use, which is provided with groove, the internal spline of transition sleeve, also is provided with groove, axle-steel silk gear
Circle is stuck between the groove of the groove of external splines and transition sleeve internal spline so that external splines axial location is fixed, meanwhile, simplify and add
Work and assembly technology, improve splined shaft intensity.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another structural representation of the present utility model.
Fig. 3 is external splines schematic diagram of the present utility model.
Fig. 4 is transition sleeve diagrammatic cross-section of the present utility model.
Embodiment
One kind is used for powerdriven spline structure, reference picture 1, and the structure includes external splines 1 and transition sleeve 3, described
External splines 1 is arranged in the internal spline of transition sleeve 3, and the boss on external splines 1 is stuck in the groove of internal spline.
Further, reference picture 2, Fig. 3, described external splines 1 are provided with the groove coordinated with axle-steel silk back-up ring 2, axle
Installed in a groove with elastic spring 2, the internal spline of described transition sleeve 3 is provided with the indent coordinated with axle-steel silk back-up ring 2
Groove, external splines 1 is installed in the internal spline of transition sleeve 3 by axle-steel silk back-up ring 2, and axle-steel silk back-up ring 2 is first stuck in external splines 1
Groove in, then by the effect of external force axle-steel silk back-up ring 2 is moved in the groove of the internal spline of transition sleeve 3, by external splines 1
In the internal spline for being positioned at transition sleeve 3.
