Description
Technical field
The present invention relates to automobile more particularly to a kind of automobile drive axle wheel hub end structures.
Background technology
Existing drive axle wheel end is made of axle bearing, semiaxis, adapter sleeve, ABS gear rings, oil sealing, axle tube flange etc.,
Axle bearing is inner ring separate type ball bearing, and the bearing life is sensitive to clearance, when bearing is in positive clearance, axle bearing meeting
Rapid damage.The axle bearing clearance is by radial interference and axial pre tightening force common guarantee, and axle bearing axial pre tightening force is by tight
Gu the interference frictional force of set and semiaxis provides, if generating wriggling, axis of the adapter sleeve to axle bearing between adapter sleeve and semiaxis
Weaken to pretightning force, causes bearing axial play to increase, bearing wear is caused to fail.
Invention content
The present invention provides a kind of automobile drive axle wheel hub end structure, including semiaxis, axle bearing, brake assembly, after
Axle housing body, disk spring, adapter sleeve, the semiaxis are connected with the brake assembly, the rear axle housing body, the axle bearing
Be installed on the semiaxis outer surface with the adapter sleeve, the disk spring be set to the axle bearing and the adapter sleeve it
Between, the disk spring is installed on the semiaxis outer surface, is compressed when the adapter sleeve generates wriggling with the axle bearing
The disk spring, existing axial elasticity power always after disk spring compression, ensure that the adapter sleeve to described half
Axle bearing existing axial pre tightening force always.
As a further improvement on the present invention, the disk spring quantity is at least 1.
As a further improvement on the present invention, it is additionally provided with semiaxis clamp spring on the semiaxis.
As a further improvement on the present invention, the rear axle housing body is equipped with axle housing flange.
As a further improvement on the present invention, the adapter sleeve outer surface is equipped with ABS gear rings, axle housing oil sealing, the ABS
Gear ring is located at the front end of the axle housing oil sealing.
The beneficial effects of the invention are as follows:New wheel hub end structure improves bearing life, drives bridge reliability higher, Ke Yiyou
Effect reduces Aftermarket Claims rate, promotes user satisfaction.
Description of the drawings
Fig. 1 is the hub end structure chart of the present invention;
Fig. 2 is the disk spring figure of the present invention.
Specific implementation mode
As shown in Figs. 1-2, the invention discloses a kind of automobile drive axle wheel hub end structures, including semiaxis 1, axle bearing
3, brake assembly 2, rear axle housing body 10, disk spring 5, adapter sleeve 6, the semiaxis 1 and the brake assembly 2, it is described after
Axle housing body 10 is connected, and the axle bearing 3 and the adapter sleeve 6 are installed on 1 outer surface of the semiaxis, and the disk spring 5 is set
Between the axle bearing 3 and the adapter sleeve 6, the disk spring 5 is installed on 1 outer surface of the semiaxis, when described tight
Admittedly set 6 compresses the disk spring 5 when generating wriggling with the axle bearing 3, the disk spring 5 is existing always after compressing
Axial elasticity power ensure that the adapter sleeve 6 to the existing axial pre tightening force always of the axle bearing 3.
5 quantity of the disk spring is at least 1.
Semiaxis clamp spring 9 is additionally provided on the semiaxis 1.
The rear axle housing body 10 is equipped with axle housing flange 4.
The adapter sleeve outer surface is equipped with ABS gear rings 7, axle housing oil sealing 8, and the ABS gear rings 7 are located at the axle housing oil sealing
8 front end.
Always there is axial elasticity power in disk spring 5, ensure that bearing has axial pre tightening force always, avoid fastening after compressing
Set 6 increases with axial pre tightening force decrease, bearing axial play caused by the generation wriggling of axle bearing 3, and bearing premature wear loses
Effect.
Disk spring 5 can compensate the adapter sleeve 6 caused by 6 end face squareness of adapter sleeve and be deposited with the undertaking of semiaxis axis 3 contacting surface
Minim gap, avoid the gap cause axle bearing 3 generate wriggling.
The beneficial effects of the invention are as follows:New wheel hub end structure improves bearing life, drives bridge reliability higher, Ke Yiyou
Effect reduces Aftermarket Claims rate, promotes user satisfaction.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
The specific implementation of the present invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention's
Protection domain.
