The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-5, electromagnetic clutch type repeatable folding and unfolding locking wheel mechanism of the present utility model is comprised of wheel shaft, wheel hub, spoke, wheel rim four parts, wherein take turns spindle unit and comprise bearing seat 14, outer shaft backup bearing 13, axle sleeve 15, magnetic clutch absorption end 4, magnetic clutch is adsorbed end 3, outside thread axle 5, interior axle backup bearing 19, intermediate solid drive shaft 2; Wheelboss part comprises drive nut 8, pushes away a bearing 18, multi-direction movement pushes away seat 16; The spoke parts comprise fixedly spoke 10, slip spoke 9, copper sheathing 17, spoke push rod 11; The wheel rim parts are wheel rim skewback 12.Wherein, described outside thread axle 5 is arranged on bearing seat 14 by outer shaft support bearing 13, it is affixed that the axle head of outside thread axle 5 and magnetic clutch are adsorbed end 3, intermediate solid drive shaft 2 is installed on outside thread axle 5 inside by interior axle backup bearing 19, one end of intermediate solid drive shaft 2 and magnetic clutch absorption end 3 are affixed, the other end and fixedly spoke 10 is affixed, drive nut 8 is connected by motion thread with outside thread axle 5, pilot bar 7 is fixed in drive nut 8 lower ends, and be installed in nut slide rail 6, multi-direction movement pushes away seat 16 and is connected with drive nut 8 by pushing away a bearing 18, it is hinged that radially well-distributed spoke push rod 11 1 ends and multi-direction movement push away seat 16, the other end and slip spoke 9 are hinged, slip spoke 9 forms sliding pairs by copper sheathing 17 and fixing spoke 10, wheel rim skewback 12 is affixed with slip spoke 9.
The specific implementation process is as follows: motor rotates by gear 1 driving intermediate solid drive shaft 2, and magnetic clutch absorption end 4 is connected and realizes that radial location, magnetic clutch are adsorbed end 3 and outside thread axle 5 passes through interval 120 by key with intermediate solid drive shaft 2 .three screws connect.
When magnetic clutch separates, static with the hinged outside thread axle 5 of intermediate solid drive shaft 2, drive nut 8 transfixions.The fixedly spoke 10 affixed with intermediate solid drive shaft 2, form the slip spoke 9 of sliding pairs with fixing spoke 10, with the hinged spoke push rod 11 of slip spoke 9, with the hinged multi-direction movement of spoke push rod 11, push away seat 16 and be fixed in wheel rim skewback 12 on the slip spoke and synchronize rotation with it under the driving of intermediate solid drive shaft 2.
When disengaging of clutch, outside thread axle 5 stops operating, and wheel is in the integral locking state, i.e. the wheel hub of wheel, wheel shaft, spoke, being integrally formed of wheel rim wheel.Then, the rotation by its intermediate solid drive shaft 2 drives the driving functions that spoke and wheel rim rotate to realize wheel.
During the power-transfer clutch adhesive, outside thread axle 5 is synchronizeed rotation with intermediate solid drive shaft 2, because pilot bar 7 and guide rail 6 have limited the circumferential movement of drive nut 8, drive nut 8 moves when threaded shaft 5 rotates outside vertically, and promote the multi-direction movement hinged with it and push away 16 and move vertically, simultaneously, multi-direction movement pushes away circumferentially rotation of seat 16; Spoke push rod 11 is in the time of intermediate solid drive shaft 2 rotation, do the Planar Compound motion in plane of rotation, the slip spoke 9 that is hinged on spoke push rod 11 1 ends radially moves, and then drives the wheel rim skewback 12 be fixed on slip spoke 9 and radially move, and makes the radial dimension of wheel adjusted.
Principle of work of the present utility model is: motor drives intermediate solid drive shaft to rotate by gear transmission, when the power-transfer clutch adhesive, intermediate solid drive shaft drives the outside thread axle and synchronously rotates, because pilot bar and guide rail have limited the axial motion of drive nut, drive nut moves when threaded shaft rotates outside vertically, and the promotion multi-direction movement hinged with it pushes away seat motion vertically, multi-direction movement pushes away seat drive spoke push rod and does plane motion, and then driving and the affixed slip spoke of wheel rim skewback radially move, thereby realized the adjusting of wheel radial dimension; When disengaging of clutch, the outside thread axle stops operating, and wheel is in the integral locking state, i.e. the wheel hub of wheel, wheel shaft, spoke, being integrally formed of wheel rim wheel, and the driving functions of wheel just can rotate to realize by intermediate solid drive shaft rotating drive spoke and wheel rim.
Electromagnetic clutch type repeatable folding and unfolding locking wheel mechanism of the present utility model has manoevreability preferably, under deployed condition, can cross than high obstacle, while running into than soft surface, gap between the wheel rim skewback and wheel rim texture can increase high-wheeled tractive force, improve whole obstacle performance and the turning efficiency of wheel; Can reduce the car body height of center of mass folded state is next, improve moving velocity and driving efficiency, obtain better riding comfort and stability, also can meet the pipeline of height-limited system and the crossing ability in tunnel, and then strengthen the comformability of complex-terrain wheeled mobile robot vehicle to the destructuring landform.
