Abstract
The utility model discloses a kind of transfer case of speed change, including：Seal case, drive shaft and transfer axis, the drive shaft and transfer axis are arranged in parallel in seal case, several driving wheels are disposed in the drive shaft, the diameter of several driving wheels is reduced successively, the several and one-to-one follower of driving wheel is disposed on the transfer axis, the diameter of the follower successively increases, 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 in the seal case, tensioning wheel corresponding with belt is provided at the top of the lifting drive.The transfer case of speed change described in the utility model utilizes the rise of different lifting drives so that tensioning wheel is tensioned different belts, and the driving wheel of different-diameter is combined with follower, thus it is possible to vary the rotating speed of transfer axis, the cost of operation and maintenance are low.
Description
Technical field
The utility model is related to transfer case technical field more particularly to a kind of transfer cases of speed change.
Background technology
Transfer case is the device for being allocated the power of engine, by switching can output power to rear axle 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 carry out speed change, affect the convenience used, it is necessary to improve.
Utility model content
The purpose of this utility model is to provide a kind of transfer cases of speed change, realize the variation of transfer axis output speed, carry
Lift operations and safeguard convenience.
For this purpose, the utility model uses following technical scheme：
A kind of transfer case of speed change, including：Seal case, drive shaft and transfer axis, the drive shaft are parallel with transfer axis
It is arranged in seal case, several driving wheels is disposed in 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 on the transfer axis, 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 in the seal case several
Lifting drive between driving wheel and corresponding follower respectively, the lifting drive top is provided with and skin
With corresponding tensioning wheel.
Wherein, it is provided with sealing cover on the seal case.
Wherein, bearing corresponding with drive shaft and transfer axis respectively is provided on the seal case.
Wherein, the drive shaft front end is provided with the splined shaft extended to outside seal case.
Wherein, the transfer axis front end is provided with the connecting shaft extended to outside seal case.
Wherein, the lifting drive is electric telescopic rod, pneumatic cylinder or hydraulic cylinder.
Wherein, the protective baffle plate positioned at driving wheel and follower both sides is respectively arranged on the seal case inner wall.
The beneficial effects of the utility model：A kind of transfer case of speed change, utilizes the rise of different lifting drives so that
Tensioning wheel is tensioned different belts, completes connection of the driving wheel with corresponding follower, realizes drive shaft to transfer axis
Driving, and the driving wheel of different-diameter is combined with follower, thus it is possible to vary the rotating speed of transfer axis, easy to operate, structure letter
Clean, the cost of operation and maintenance is low.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of transfer case of speed change, including：Seal case 1, drive shaft 2 and transfer axis 3, the drive shaft 2 and transfer axis 3
Be arranged in parallel in seal case 1, be disposed with several driving wheels 7 in the drive shaft 2, several driving wheels 7 it is straight
Footpath is reduced successively, and several and 7 one-to-one follower 8 of driving wheel, the follower 8 are disposed on the transfer axis 3
Diameter successively increase.In the case of 2 invariablenes turning speed of drive shaft, the driving wheel 7 of different-diameter is combined with follower 8, thus it is possible to vary
The output speed of transfer axis 3, it is simple for structure.
Belt 6 is respectively arranged between the driving wheel 7 and corresponding follower 8 to be connected, and is set in the seal case 1
Several lifting drives 4 between driving wheel 2 and corresponding follower 8 respectively are equipped with, the lifting drive 4 pushes up
Portion is provided with and 6 corresponding tensioning wheel 5 of belt.Utilize the rise of different lifting drives 4 so that tensioning wheel 5 is to different
Belt 6 is tensioned, and completes connection of the driving wheel 7 with corresponding follower 8, realizes driving of the drive shaft 2 to transfer axis 3.
In the present embodiment, sealing cover is provided on the seal case 1, easy for installation, dust seal is good, strengthens internal
The protection of portion's structure.
In the present embodiment, it is provided with respectively with 3 corresponding bearing of drive shaft 2 and transfer axis, is promoted on the seal case 1
The rotation flexibility of drive shaft 2 and transfer axis 3.
In the present embodiment, 2 front end of drive shaft 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, 3 front end of transfer axis 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 be electric telescopic rod, pneumatic cylinder or hydraulic cylinder, scaling operation side
Just.
In the present embodiment, it is respectively arranged on 1 inner wall of seal case positioned at 8 both sides of driving wheel 7 and follower
Protective baffle plate 9 avoids belt 6 from being flown off from driving wheel 7 or follower 8, promotes stability in use.
More than content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
Limitation to the utility model.
