In a mechanical device, a driving device is an important component, and the driving device can provide power required by the mechanical motion of the device, so that an executing part of the device can complete operations based on the mechanical motion, such as translation, rotation, clamping and the like. The mechanical equipment comprises movable mechanical equipment, such as vehicles like automobiles and agricultural machinery like tractors, the mechanical equipment usually realizes the position movement of the mechanical equipment by a way that a rotating wheel contacts with the ground to roll, wherein the rotating wheel is connected with a motor, a speed reducer, a transmission structure and other parts to acquire power, and the rotating wheel and the parts form a driving device.

The inventor researches and discovers that the driving device of the existing movable mechanical equipment directly installs components such as a motor, a speed reducer and the like on the rotating shaft of the rotating wheel, or installs controllers and parts such as the motor, the speed reducer, a brake and the like around the hub of the rotating wheel to control the rotating wheel, and the driving device occupies larger space in the axis direction of the rotating wheel, so that the whole volume of the mechanical equipment is larger, the mechanical equipment is unfavorable for running in a narrower environment, and interference, collision and winding with objects in the surrounding environment are easy to occur.

When the integrated driving device is used, the driven wheel 310 drives the connecting shaft 330 to rotate, the connecting shaft 330 penetrates through the slewing bearing 370 and drives the inner ring of the slewing bearing 370 to rotate, and the inner ring of the slewing bearing 370 drives the supporting wheel 320 to rotate through the connecting disc.

Since the mass of the support wheel 320 is large compared to the driven wheel 310, a firm support is required in use, and stability of the connection shaft 330 is required. Therefore, the slewing bearing 370 is provided, so that the supporting wheel 320 and the connecting shaft 330 can be more firmly supported, the inner ring of the slewing bearing 370 is fixedly connected with the supporting wheel 320, and the outer ring of the slewing bearing 370 is fixedly connected with the second connecting flange 150, so that the supporting wheel 320 and the connecting shaft 330 can freely rotate, and meanwhile, the supporting function of the slewing bearing 370 is obtained. The location of the second connecting flange 150 may be designed according to the structure of the support frame 100 and the pivoting support 370, and the requirement of the installation location of the pivoting support 370, for example, in some embodiments of the present application, as shown in fig. 5, the second connecting flange 150 may be directly disposed on the bottom wall 111 of the accommodating cavity 110.

In the above embodiment, the slewing bearing 370 is provided, and the outer ring of the slewing bearing 370 is fixed on the side wall of the supporting frame 100, so as to provide support for the connecting shaft 330, thereby further improving the stability of the connecting shaft 330.

To avoid interference or damage to the integrated drive from the external environment, in some embodiments, optionally, referring to fig. 5, a washer 380 is sandwiched between the bearing 350 and the support wheel 320 for covering the slewing bearing 370.

In the above embodiment, since the slewing bearing 370 is exposed to the external environment, the slewing bearing 370 may be disturbed or destroyed by the external environment during long-term use, and the gasket 380 is provided to cover the slewing bearing 370, so as to prevent dust or other impurities in the external environment from entering the slewing bearing 370, and prevent the external environment from disturbing or destroying the driving device. Wherein, the gasket 380 may be made of nylon or other flexible material; the washer 380 is provided between the support wheel 320 and the slewing bearing 370, so long as the slewing bearing 370 can be covered.

In some embodiments, optionally, one end of the connecting shaft 330 is flat-keyed to the driven wheel 310, and the other end of the connecting shaft 330 is splined to the support wheel 320.

Flat keys are lower in cost than splines, but cannot bear larger loads, in this embodiment, the driven wheel 310 has smaller mass, flat key connection can be used for cost reduction, and the supporting wheel 320 has larger mass, so that spline connection is considered for meeting performance requirements.

The above embodiment provides a preferred solution for coupling the coupling shaft 330 with the driven wheel 310 and coupling the coupling shaft 330 with the supporting wheel 320 in combination with performance requirements and cost.

To achieve a drive connection of the drive pulley 220 with the driven pulley 310, in some embodiments, the drive pulley 220 is optionally in drive connection with the driven pulley 310 by a chain or belt.

The embodiment of the present application needs to connect the driving wheel 220 with the driven wheel 310 in a driving manner, so that the driven wheel follows the driving wheel 220 to rotate, and transmit power to the supporting wheel 320. When the driving wheel 220 is connected with the driven wheel 310 through a chain or a belt, the transmission efficiency is higher, and the replacement and the maintenance can be more convenient. Referring to fig. 2, fig. 2 illustrates an example of a chain drive connection between the driving wheel 220 and the driven wheel 310, but is not limited thereto. In addition, the driving wheel 220 and the driven wheel 310 can be in transmission connection through other modes such as gears, and when the driving wheel 220 and the driven wheel 310 are in transmission connection through the mode of the gears, the structure can be more compact.

In the above embodiment, the transmission connection between the driving wheel 220 and the driven wheel 310 may have various implementation manners, and the connection manner is flexible, so that the device can be compatible with more usage scenarios.

When the driving pulley 220 and the driven pulley 310 are connected by a chain or belt transmission, the transmission efficiency is reduced because the chain or belt may lose part of its elasticity after long-term use, and the efficiency of the chain or belt transmission can be improved by providing the tensioner 140, thereby improving the driving performance of the driving device. The tensioner 140 may be an elastic structure, where one end of the tensioner is fixedly disposed at a position between the driving wheel 220 and the driven wheel 310 in the accommodating cavity 110, and the other end of the tensioner has an abutting portion abutting against the chain or the belt, and two ends of the tensioner 140 are elastically connected, so that the abutting portion is always contacted with the chain or the belt, and is extruded to be in a tensioning state, thereby avoiding the problem that the chain or the belt falls off due to loosening or affects the transmission efficiency. In addition, the tensioner 140 may be of other telescopic adjusting structure, and in use, the tensioner may be telescopic adjusted in advance according to the tightness of the belt or chain.
