Abstract
The invention discloses a kind of transfer case of speed change, it includes：Seal case, drive shaft and transfer axle, the drive shaft and transfer axle are set in parallel in seal case, several driving wheels are disposed with the drive shaft, the diameter of several driving wheels is reduced successively, the several and one-to-one follower of driving wheel is disposed with the transfer axle, the diameter of the follower increases successively, belt is respectively arranged between the driving wheel and corresponding follower to be connected, several lifting drives between driving wheel and corresponding follower respectively are provided with the seal case, tensioning wheel corresponding with belt is provided with the top of the lifting drive.The transfer case of speed change of the present invention, utilize the rise of different lifting drives so that tensioning wheel is tensioned to different belts, and the driving wheel of different-diameter combines with follower, thus it is possible to vary the rotating speed of transfer axle, the cost of operation and maintenance are low.
Description
Technical field
The present invention relates to transfer case technical field, more particularly to a kind of transfer case of speed change.
Background technology
Transfer case is the device for being allocated the power of engine, and rear axle can be output power to by switching, or
Person is output to front axle and rear axle simultaneously.
Common transfer case generally use gear or chain are rotated, and from great, high energy consumption, and need gear oil
It is lubricated, maintenance cost is high, it is difficult to carries out speed change, have impact on the convenience used, it is necessary to improve.
The content of the invention
It is an object of the invention to provide a kind of transfer case of speed change, realizes the change of transfer axle output speed, lifting behaviour
Make and safeguard convenience.
To use following technical scheme up to this purpose, the present invention：
A kind of transfer case of speed change, including：Seal case, drive shaft and transfer axle, the drive shaft are parallel with transfer axle
It is arranged in seal case, several driving wheels is disposed with the drive shaft, the diameter of several driving wheels subtracts successively
It is few, the several and one-to-one follower of driving wheel is disposed with the transfer axle, the diameter of the follower increases successively
Add, being respectively arranged with belt between the driving wheel and corresponding follower is connected, and is provided with the seal case several
Lifting drive between driving wheel and corresponding follower respectively, the lifting drive top is provided with and skin
Tensioning wheel corresponding to band.
Wherein, it is provided with closure on the seal case.
Wherein, bearing corresponding with drive shaft and transfer axle respectively is provided with the seal case.
Wherein, the drive shaft front end is provided with the splined shaft extended to outside seal case.
Wherein, the transfer axle front end is provided with the connecting shaft extended to outside seal case.
Wherein, the lifting drive is electric expansion bar, pneumatic cylinder or hydraulic cylinder.
Wherein, the protective baffle plate positioned at driving wheel and follower both sides is respectively arranged with the seal case inwall.
Beneficial effects of the present invention：A kind of transfer case of speed change, utilizes the rise of different lifting drives so that tensioning
Wheel is tensioned to different belts, is completed driving wheel and the connection of corresponding follower, is realized drive of the drive shaft to transfer axle
It is dynamic, and the driving wheel of different-diameter combines with follower, thus it is possible to vary the rotating speed of transfer axle, it is easy to operate, it is simple for structure, make
With low with the cost of maintenance.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Technical scheme is further illustrated with reference to Fig. 1 and by specific embodiment.

The rotation flexibility of drive shaft 2 and transfer axle 3.
In the present embodiment, the front end of drive shaft 2 is provided with the splined shaft 10 extended to outside seal case 1, it is convenient with
The connection of motor, engine or its gearbox.
In the present embodiment, the front end of transfer axle 3 is provided with the connecting shaft 11 extended to outside seal case 1, it is convenient with
The connection driving of other devices.
In the present embodiment, the lifting drive 4 is electric expansion bar, pneumatic cylinder or hydraulic cylinder, scaling operation side
Just.
In the present embodiment, it is respectively arranged with the inwall of seal case 1 positioned at driving wheel 7 and the both sides of follower 8
Protective baffle plate 9, avoid belt 6 from being flown off from driving wheel 7 or follower 8, lift stability in use.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to the present invention's
Thought, there will be changes, this specification content should not be construed as to the present invention in specific embodiments and applications
Limitation.
