Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention；
Fig. 2 is the partial structural diagram when present invention is connected with wheel；
Fig. 3 is the structural representation of supporting device.
Embodiment
Technical scheme is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, aircraft floor, which slides wheel drive system, includes frame 1, power set 2, gearbox
3rd, rotating disk 4, supporting device and auxiliary wheel 8.Wherein, frame 1 is an installation pedestal of the system, and it includes ground surface end 101
With wheel end 102, power set and gearbox are fixedly mounted on the wheel end of frame, and the rotating shaft of power set is gearbox
Input shaft；Rotating disk is installed on the side of gearbox by bearing, and the rotating shaft of rotating disk is the output shaft of gearbox, and rotating disk can be around its axle
Rotate.Supporting device is located at side of the rotating disk away from gearbox, and it includes two shored oil cylinders and two are shored hoof, wherein, the
One shored oil cylinder 501 and the second axial symmetry centered on the rotating shaft of rotating disk of shored oil cylinder 502 are fixed on rotating disk, its piston direction
Conversely；First shore hoof 601 shored with second hoof 602 structure it is identical, including rotating shaft end 6001, expansion end 6002 and arc
Shape portion 6003, rotating shaft end are provided with the hole of installation pin 701 and 702, and expansion end is provided with the part being connected with shored oil cylinder piston, arc
The outer surface in shape portion matches with the inwall of half wheel hub 901 on the outside of wheel；First shores the rotating shaft end of hoof by pin 701 and turns
Disk is connected, and expansion end is connected with the piston of the first shored oil cylinder；The second rotating shaft end for shoring hoof is connected by pin 702 and rotating disk
Connect, expansion end is connected with the piston of the second shored oil cylinder；Piston movement can drive first shore hoof and second shore hoof rotating around
Pin rotation thereon, pin shore the rear that hoof is located at rotating disk turning circumference direction both with respect to it, and first shores hoof and
Two, which shore hoof outer surface, is covered with one layer of flexible material, and it will not be caused to damage when contacting wheel hub.Auxiliary wheel is arranged on machine
The one end of frame kink away from power set, can freely be rotated.
During installation, as shown in Fig. 2 rotating disk and supporting device are located at hub interior hollow space, first shores hoof and second
The outer surface for shoring hoof is coordinated by the inwall of half wheel hub 901 on the outside of one layer of flexible material and wheel, and 902 be in wheel in figure
The wheel hub of side half.
In system work process, the first shored oil cylinder and the second shored oil cylinder respectively push out piston, so as to respectively
Make first to shore hoof and second to shore hoof and move radially outwards, contact and extrude the radially inner side of half wheel hub on the outside of wheel, by
The flexible material that its surface pastes does buffering and fixed with wheel extruding.In addition, moment of torsion inputs gearbox as caused by power set,
Gearbox is transferred to rotating disk after moment of torsion is amplified, driving rotating disk rotates, and drives supporting device to rotate, so as to impart power to
Wheel.Hoof and second is shored with the first of the installation of direction as shown Central Symmetry to shore hoof and can strengthen locking automatically.During this,
Auxiliary wheel wheel direction of motion rear ground surface, the support force from ground can resist driving machine wheel rotate caused by
Reverse torsion, frame will be prevented to be rotated in the presence of TORQ, the system can drive wheel steadily to run forward.
