Abstract
The utility model relates to a wheel device suitable for running on soft road surface such as sand. The utility model is comprised of a cavity shape outer wheel arranged penetrating slot holes on the peritheca, an impeller suited in the cavity of the outer wheel through a supporting bearing and a hollow axle which outer end is connected with the vehicle body, a reducer fixed in the hollow axle and a motor driving and connecting the reducer, and an impeller hinged on the flange of the impeller and inserted in the penetrating slot holes on the peritheca of the outer wheel; the impeller is connected with the output axle of the reducer, and a pretightening force spring is connected between the outer wheel and the impeller and the spring is used to limit the outer wheel and the impeller. The utility model can improve the ground adhesive force through the impeller extended from the wheel, to increase the tractive force, therefore to effectively enhance stronger passing capacity and smoothness of vehicles on soft road surface.
Description
Technical field
The utility model relates to a kind of wheel mechanism of travelling at soft surfaces such as sand grounds of suiting.
Background technology
When conventional wheel is walked on soft road surface such as sand ground, can skid and cause the crossing ability difference even can't walk because sink.In order to solve the shop problem of vehicle on soft terrain, Chinese scholars proposes and has developed multiple walking wheel mechanism, and existing walking wheel mechanism is actually a polygon that can roll, when rolling on the ground, a polygon can produce polygon effect, be that walking is taken turns when rolling, its core wheel can fluctuate up and down, and speed is also inhomogeneous, for example when the leg number was 4, wheel momentary velocity maxim and minimum value can differ from one times; And in some cases, when for example turning to, the speed difference of left and right wheels, can cause the asynchronous of the right and left wheel rolling, in that left and right wheels is asynchronous when striding, can makes car body produce and rock, bring very big vibration to man-machine, cause vehicle to lose the ride comfort of conventional wheel continuous rolling.
Summary of the invention
The purpose of this utility model is for overcoming the shortcoming that there is the riding comfort difference in existing walking wheel, proposing a kind of composite type walking wheel mechanism of novelty, to improve the crossing ability of wheel on soft surface and good ride comfort.
The utility model composite type walking wheel mechanism, be by a cavity shape foreign steamer that on perisporium, has an inside and outside penetrating slotted eye, by backup bearing be sleeved on impeller in the foreign steamer inner chamber and outer end be connected hollow shaft on the car body, be installed in the retarder in the hollow shaft and drive connection reducer motor, be hinged on the bead of impeller and intert that the blade in the penetrating slotted eye constitutes on the foreign steamer perisporium; Said impeller is connected with the output shaft of retarder, also is connected between foreign steamer and the impeller and limits the two prefastening force spring in relative rotation.
The utility model composite type walking wheel mechanism, when vehicle was absorbed in sand ground, the blade that can utilize wheel to stretch out improved ground-surface adhesive ability, and tractive force is increased, Gu and actv. strengthens the operational capability of vehicle under soft environment such as sand ground.The characteristics that also kept simultaneously circular wheel have advantage such as travel steadily, and actv. has been eliminated the polygon effect of existing walking wheel.Both can be used for vehicle, can be used as the driving traveling gear of the moon or planetary detection car again in soft surface operations such as sand ground or paddy fields.Assemble the vehicle of this wheel, have stronger crossing ability and ride comfort, and this kind composite type walking wheel relies on self structure characteristics and the ground condition of adhering to realize the flexible of blade adaptively without any need for external control mechanism fully at soft surface.
Description of drawings
Fig. 1 is the front view of composite type walking wheel mechanism;
Fig. 2 is that the side of composite type walking wheel mechanism is cutd open scheme drawing.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model structure.
With reference to Fig. 1,2, a kind of composite type walking wheel mechanism, be by a cylindrical shape foreign steamer 2 that on perisporium, has an inside and outside penetrating slotted eye 4, by backup bearing 3 be sleeved on impeller 9 in foreign steamer 2 inner chambers and outer end be connected hollow shaft 5 on the car body, be installed in retarder 7 hollow shaft 5 in and driving connection reducer 7 motor 6, be hinged on the bead of impeller 9 and intert that the blade 8 in the penetrating slotted eye 4 constitutes on foreign steamer 2 perisporiums; Said impeller 9 is connected with the output shaft of retarder 7, also is connected one between foreign steamer 2 and the impeller 9 and can limits the two prefastening force spring 1 in relative rotation.
Said impeller 9 is the blind chamber tubes that have bead on the outer wall, is sleeved on the outer wall of hollow shaft 5 by the bearing 10 that is arranged in its chamber tube.
Said prefastening force spring 1 is a plane scroll spring, and its inner is connected on the end wall of impeller 9, and its outer end is connected on the end cap 11 of foreign steamer 2.
Described blade 8, present embodiment are provided with six, and the one end passes through the circumferentially uniform hinge of bearing pin 12 respectively on the bead of impeller 9, and its other end is plugged on respectively in six uniform on foreign steamer 2 perisporiums penetrating slotted eyes 4.
The principle of work of this composite type walking wheel mechanism is: motor 6 is by the output shaft output torque of retarder 7, and impeller 9 is rotated.The rotation of impeller will be pushed volute spiral spring 1, by spring output torque is sent to the end cap 11 of foreign steamer 2, drives the end cap rotation, because end cap is fixed into one by screw and foreign steamer, so driven the rotation of foreign steamer.Need only the predetermincd tension of rational regulating spring because foreign steamer 2 and in-to-in impeller 9 rotate synchronously this moment, and blade 8 can not stretched out outside the wall of foreign steamer 2.In wheel travels, when in case sagging situation having occurred, the degree of depth of imbedding in the soil along with wheel increases, and the resisting moment that causes foreign steamer 2 to be subjected to also increases thereupon, thereby the rotating speed of foreign steamer will descend, this moment, spring further pushed, foreign steamer and internal impeller will be rotated no longer synchronously, so blade 8 will stretch out from the slotted eye 4 of foreign steamer 2, penetrate in the sandy soil, thereby increased the adhesive ability and the tractive force of wheel, effectively raised the power-handling capability of vehicle under soft environment.
