Abstract

The invention discloses a driving wheel system capable of realizing universal rotation. The driving wheel system comprises a wheel (1), a wheel axle (2), a wheel axle tapered roller bearing (3), a wheel axle housing (4), a check washer (5) for a wheel axle disc nut, the wheel axle disc nut (6), a direct-current motor (7), a motor fixing housing (8), a steering shaft (9), a rotating shaft sleeve (10), a frame (11), a rotating shaft tapered roller bearing (12), a check washer (13) for a rotating shaft disc nut, and the rotating shaft disc nut (14). When a torque is applied to the steering shaft (9), the steering shaft (9) drives the motor fixing housing (8), the direct-current motor (7), the wheel axle housing (4), the wheel axle (2) and the wheel (1) to rotate relative to the frame (11) so that independent steering is realized. A vehicle can be steered in situ and driven linearly, obliquely, horizontally and the like so as to operate in a narrow space.

Description

A kind of universal rotational drive train
Technical field
The present invention relates to a kind of drive train, especially a kind of universal rotational drive train.
Background technology
All be connected by draft hitch between the drive wheel of present most of vehicle and the vehicle frame, power passes to drive wheel by universal driving device.When drive wheel during simultaneously as wheel flutter, be subjected to the universal driving device structural limitations, can only rotate within the specific limits.In addition, the manual steering system of the vehicle body frame structure for automotive of unifying has also limited the steering angle of wheel flutter.And for the vehicle of some special purposes, moving velocity is not high, but requires to turn to flexibly, and steering angle is unrestricted, can realize the four-wheel independent steering, need to finish pivot stud, and straight line, oblique, cross running etc. are so that at operation in narrow space.
Summary of the invention:
The object of the invention is to for the deficiencies in the prior art, a kind of drive train that can realize universal rotational is provided.
Technical scheme of the present invention comprises: wheel (1), wheel shaft (2), wheel shaft tapered roller bearing (3), wheel axle housing (4), wheel shaft circular nut stop washer (5), wheel shaft circular nut (6), DC machine (7), motor set casing (8), steering shaft (9), rotating shaft cover (10), vehicle frame (11), rotating shaft tapered roller bearing (12), rotating shaft circular nut stop washer (13), rotating shaft circular nut (14), it is characterized in that: be bolted between wheel (1) and the wheel shaft (2), pair of axle spindles tapered roller bearing (3) is installed between wheel shaft (2) and the wheel axle housing (4), wheel shaft circular nut (6) is in axial direction restriction wheel shaft tapered roller bearing (3) position, and its elasticity of capable of regulating.The wheel shaft circular nut limits the rotation of wheel shaft circular nut (6) with stop washer (5).
Above-mentioned a kind of universal rotational drive train, DC machine (7) is connected with motor set casing (8) by socket head cap screw, and motor set casing (8) is bolted to connection with wheel axle housing (4).DC machine (7) by flat key to wheel shaft (2) transmitting torque.
Above-mentioned a kind of universal rotational drive train, steering shaft (9) is captiveed joint by socket head cap screw with motor set casing (8), one countershaft tapered roller bearing (12) is installed between steering shaft (9) and the rotating shaft cover (10), by the position of rotating shaft circular nut (14) at axial direction restriction rotating shaft tapered roller bearing (12), and its elasticity of capable of regulating.The rotating shaft circular nut limits the rotation of rotating shaft circular nut (14) with stop washer (13).Rotating shaft cover (10) is welded on the vehicle frame (11).
The present invention has reduced the too much mechanical drive in common vehicle chassis, has alleviated complete vehicle weight.When wheel tied up to as the outside outputting power of drive wheel, vehicle frame four-wheel independent steering can be realized the multiple form that turns to relatively.
Description of drawings
Fig. 1 is a kind of universal rotational drive train cutaway view.
The specific embodiment
Be bolted to connection between wheel (1) and the wheel shaft (2) as shown in Figure 1, pair of axle spindles tapered roller bearing (3) is installed on wheel shaft (2) and the wheel axle housing (4), limits wheel shaft tapered roller bearing (3) position with stop washer (5) at axial direction by wheel shaft circular nut (6) and wheel shaft circular nut.With respect to wheel axle housing (4) rotation, wheel shaft (2) is accepted the power input from DC machine (7), band motor car wheel (1) rotation by a pair of tapered roller bearing (3) for wheel shaft (2) and wheel (1).
Wheel axle housing (4) and motor set casing (8) are bolted to connection, and DC machine (7) is captiveed joint by socket head cap screw with motor set casing (8), and wheel axle housing (4), motor set casing (8), DC machine (7) are assembled into a global facility.Captive joint by socket head cap screw between steering shaft (9) and the motor set casing (8), rotating shaft cover (10) is welded and fixed and is connected on the vehicle frame (11).Steering shaft (9) can rotate with respect to rotating shaft cover (10) by a countershaft tapered roller bearing (12).
By interconnecting between the above part, when having torque to be applied to steering shaft (9), steering shaft (9) rotates drive motor set casing (8), DC machine (7), wheel axle housing (4), wheel shaft (2), wheel (1) relative to vehicle frame (11), realize independent steering.DC machine (7) connects transmission of torque to wheel shaft (2) and wheel (1) by flat key, drive and turn to be independent of each other, the four-wheel individual drive with turn to.
