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, and switching is more stiff or parking is needed to be operated, and speed is slow, rushes greatly, reduces operation
Comfort.
Utility model content
It is switched fast the purpose of this utility model is to provide a kind of without the transfer case rushed, reduces cost, promote switching
The agility and stationarity of operation.
For this purpose, the utility model uses following technical scheme：
It is a kind of to be switched fast without the transfer case rushed, including：Babinet, main shaft and transfer axis, the main shaft and transfer between centers
Every being arranged in babinet, the first sheave is provided on the main shaft, corresponding with the first sheave is provided on the transfer axis
Two sheaves are provided with belt between first sheave and the second sheave and are connected, be provided in the babinet positioned at main shaft and
Tensioning shaft between transfer axis, the tensioning shaft is from belt, passes through below belt or above belt, and the tensioning shaft includes
Front axle, rear axle and frustum, the frustum are connected between front axle and rear axle with one heart, are provided on the outside of the babinet and are put down with tensioning shaft
Capable retractable driving device is provided with bending plate between one end of the tensioning shaft and the end of retractable driving device and is connected
It connects.
Wherein, the front-end of spindle is provided with the spline extended to outside babinet.
Wherein, the transfer axis front end is provided with the first ladder connecting shaft extended to outside babinet.
Wherein, the main shaft end is provided with the second ladder connecting shaft extended to outside babinet.
Wherein, it is provided on the wall box positioned at the first baffle group of the first sheave both sides and positioned at the second sheave
The second baffle group of both sides.
Wherein, the retractable driving device is hydraulic cylinder or pneumatic cylinder.
Wherein, the diameter of the front axle is less than the diameter of rear axle.
The beneficial effects of the utility model：It is a kind of to be switched fast without the transfer case rushed, utilize stretching for retractable driving device
Contracting drives the axial movement of tensioning shaft so that belt is oppressed by rear axle, and rear shaft diameter is big, is tensioned when oppressing belt so that
Main shaft operating synchronous with transfer axis, preceding shaft diameter is small, and the relaxation of belt can be kept to be carried without participating in transmission work using frustum
The smooth of switching has been risen, has avoided the problem rushed, and without parking, switch speed is fast, and maintenance cost is low.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
