Description
Technical field
The utility model relates to a kind of driver train of RV recreational vehicle, belongs to the RV recreational vehicle technical field.
Background technology
As shown in Figure 1, driver train scheme drawing for original RV recreational vehicle, the driver train of described RV recreational vehicle comprises wheel 1, be provided with wheel shaft 7 in the centre hole of wheel 1, wheel shaft 7 middle parts are provided with the flywheel 9 and the sprocket wheel 5 of captive joint, are provided with clutch shaft bearing 2 between wheel shaft 7 and the flywheel 9, be provided with second bearing 8 between sprocket wheel 5 and the wheel shaft 7, flywheel 9 outsides are provided with Case of fly-wheel 3, and Case of fly-wheel 3 is connected and fixed by screw thread or spline with wheel 1, and the two ends of wheel shaft 7 are located on the vehicle frame 6.
As shown in Figure 2, driver train motion principle figure for original RV recreational vehicle, flywheel 9 is provided with ratchet 4, chain drives sprocket wheel 5 rotations during use, ratchet 4 just in time is stuck on the ratchet of Case of fly-wheel 3, rotates thereby drive Case of fly-wheel 3, because Case of fly-wheel 3 is captiveed joint with wheel 1, therefore wheel 1 also is being with and is being rotated, and advances thereby drive car.This kind driver train has been continued to use the bicycle driving mode, and the junction of Case of fly-wheel 3 and wheel 1 need process or the die sinking tool, and the oad of this structure is bigger usually, Heavy Weight, and the assembling difficulty, light with Sport Activity Vehicle, simple, require inconsistent cheaply.
Summary of the invention
The purpose of this utility model provides the general wheel of a kind of use, and it is small and exquisite, light that general purpose accessory is formed, the driver train that is easy to assemble.
In order to achieve the above object, the technical solution of the utility model has provided a kind of driver train of RV recreational vehicle, comprise wheel, it is characterized in that, the centre hole two ends of wheel respectively are provided with an inserts, it between wheel and the inserts interference fit, the inserts center is provided with wheel shaft, adopt between inserts and the wheel shaft and be threaded, wheel shaft is positioned on the part of wheel both sides and respectively is provided with a sprocket wheel, be provided with unilateral bearing between sprocket wheel and the wheel shaft, the two ends of wheel shaft are provided with bearing and bearing cap shim, and wheel shaft is located on the vehicle frame by bearing.
The utility model has the advantages that: small and exquisite, light, be easy to assembling.

Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 3, be the driver train scheme drawing of RV recreational vehicle of the present utility model.The driver train of described RV recreational vehicle comprises wheel 21, and wheel 21 centre hole two ends respectively are provided with an inserts 22, and one of them inserts 22 endoporus is a minus thread, and another inserts 22 endoporus are right-hand screw thread.21 of inserts 22 and wheels are interference fit, rely on the friction force between inserts 22 and wheel 21 centre holes to make inserts 22 and 21 of wheels not relatively rotate.Inserts 22 is contained on the wheel shaft 27, and wheel shaft 27 two ends are optical axis, and centre portion is two sections screw threads, Yi Bian wherein be minus thread, another side is a right-hand screw thread, and two inserts 22 are connected with wheel shaft 27 by screw thread.The two ends optical axis of wheel shaft 27 respectively is provided with a sprocket wheel 23, the sprocket wheel endoporus is pressed with unilateral bearing 24, the characteristic of unilateral bearing 24 is that it can only a direction freely rotate in the axle upper edge, along reversing sense when stressed can and axle between produce very big friction force, the optical axis outside, two ends of wheel shaft 27 is provided with bearing 28, there is bearing cap shim 25 in bearing 28 outsides, and wheel shaft 27 is connected with vehicle frame 26 by bearing 28, can freely rotate on vehicle frame 26.
As shown in Figure 4, driver train motion principle figure for RV recreational vehicle of the present utility model, when chain drive sprocket wheel 23 is done the rotation of direction shown in the arrow, unilateral bearing 24 and 27 on wheel shaft produce huge friction force as can be known according to the characteristic of unilateral bearing, being driven wheel shaft 27 by this friction force sprocket wheel 23 moves in a similar direction, because wheel shaft 27 is provided with two inserts 22, and 27 on inserts 22 and wheel shaft combine for interference, so wheel shaft 27 can 21 rotations of drive wheels.Sprocket wheel 23 rotates with regard to drive wheels 21 like this, and then the driving car travels forward.When chain drive sprocket wheel was done the arrow counter-rotation, according to the characteristic of unilateral bearing 24, unilateral bearing 24 can rotate on wheel shaft 27 along this direction, and this moment, sprocket wheel 23 can not drive wheel 21 motions.Rely on sprocket wheel 23 propulsive effort intermittently to make wheel 21 move along the direction that car advances all the time.
Stressed scheme drawing during as shown in Figure 5, for the motion of the driver train of RV recreational vehicle of the present utility model.When sprocket wheel 23 rotates by unilateral bearing 24 live axles 27, because being located at the rotation direction of two inserts 22 screw threads on the wheel shaft 27 just in time pushes to wheel shaft 27 centers mutually on the contrary, the squeese pressure of the big more inserts 22 of wheel shaft 27 rotating torques is just big more, and inserts 22 is firm more with combining of 21 on wheel like this.
