Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described:
Embodiment 1
As shown in Figure 1 to Figure 3, a kind of running gear described in the embodiment of the present invention, including at least one wheel, it is specially and includes one, two or more wheel, the present embodiment mainly introduces the situation including two wheels, and other number wheel situations can be by that analogy.
As shown in the figure, a kind of running gear described in the present embodiment, including two wheels, two wheels are connected on vehicle frame 7 and car body centrage about whole machinery is arranged symmetrically with, under normal circumstances, the wheel installed provides onward impulse as drivewheel, therefore, each wheel is provided with independent driving device, the running gear of the present invention is without driven pulley, support whole vehicle frame 7 to replace driven pulley and follow drivewheel advance, the running gear of the present invention provides at least one supporting leg 6, when meeting whole mechanically stable, the running gear of the present invention can arrange one, two or more supporting legs 6.Supporting leg 6 is connected with vehicle frame 7 so that machinery in walking transfer to convenient, as the supporting leg 6 of slave unit, concrete connected mode is: for being rotatably connected between supporting leg 6 and car body 7.When car body 7 turns to, supporting leg 6 turns to optimum position and follows whole car body 7 simultaneously and advance.On the other hand, the bottom of supporting leg 6 should be arranged to arcuate structure, as shown in Figure 2, specifically should ensure that the side projection bottom supporting leg 6 is arc, making theoretic contact between supporting leg 6 and ground is point cantact or linear contact lay to facilitate the rotation of supporting leg 6 and to slide, certainly, in actual application, due to abrasion, the actual contact between supporting leg 6 and ground is probably face contact.As a preferred mode, supporting leg 6 and car body 7 connecting place are set to cylindrical structural, wherein, cylindrical structural is specially its axis and is perpendicular to horizontal plane, being rotatably connected as the supporting leg 6 vertical axis 360 ° rotation around the cylindrical structural on its top between supporting leg 6 and car body 7.
Wheel described in the present embodiment is mainly used in providing the effect of the vehicle frame 7 of the power advanced and the whole machinery of support, supporting leg 6 described by the present embodiment is mainly used in providing one device simply and easily to replace driven pulley, and auxiliary supports the effect of whole mechanical side vehicle frame 7 simultaneously, state on the basis of purpose in realization, the wheel of the running gear of the present invention and the combination of supporting leg 6 structure are diversified, for instance: adopt the combination of two supporting legs 6 of a wheel；Adopt the combination of one supporting leg of two wheels；Adopt the combination of a multiple supporting leg 6 of wheel；Adopt the combination of two multiple supporting legs 6 of wheel；Adopting the combination etc. of the multiple supporting leg 6 of multiple wheel, even if all adopting car wheel structure, the effect that the present invention walks in paddy field or turf moor is also significant.
Particularly illustrating two wheels in the present embodiment accompanying drawing to be arranged symmetrically with, each wheel is respectively arranged in the front and the rear with the situation of two supporting legs 6.As an embodiment having choosing, owing to walking in the farmland have crops, in order to reduce the damage to crops, in the present embodiment, the supporting leg 6 before and after each wheel is positioned at when straight ahead on identical strip path curve line with wheel, shown in accompanying drawing 3, it can be seen that the running gear described in the present embodiment is when straight ahead, the movement locus of the supporting leg 6 that each wheel and its front and back position are arranged is located along the same line.Further, running gear of the present invention is additionally provided with mud-scraping apparatus 8.
Embodiment 2
Such as Fig. 4 and Fig. 5, as a preferred mode, present embodiments providing currently preferred a kind of wheel, this wheel includes wheel hub 2 and wheel rim 1, and wheel hub 2 is connected by spoke 3 with wheel rim 1.Wheel rim 1 is seen as hollow ring, and cylinder ring seen as by wheel hub 2, and its concrete connected mode is: the dead in line of the axis of wheel hub 1 and wheel rim 1, for same straight line；The sagittal plane of wheel hub 2 (is perpendicular to the axis of wheel hub 2, and make wheel hub 2 about the plane of its symmetry) (it is perpendicular to the axis of wheel rim 1 with the sagittal plane of wheel rim 1, and make wheel rim 1 about the plane of its symmetry) parallel, two sagittal planes are misaligned, between separated by a distance so that wheel hub 2, spoke 3 and wheel rim 1 global shape spatially are truncated conical shape.Fig. 5 is front view or the rearview of the wheel of the present invention, as it is shown in figure 5, wheel hub 2 is positioned at the right side of wheel rim 1, centre is connected by spoke 3, and the projection approximation of whole wheel is in isosceles trapezoid.Further, in order to increase adhesive force over the ground during wheel is advanced, the wheel of the present invention is additionally provided with the two or more gear teeth 4, all gear teeth 4 are arranged on wheel rim 1, and be distributed along the even circumferential of wheel rim 1, it is characterized in that wheel of the present invention covers without the gear teeth at wheel rim 1 side with wheel hub 2 homonymy, as shown in the projection view of Fig. 5, at projecting direction, the gear teeth 4 are in the right edge of wheel rim 1, namely position shown in diagram A is without covering, namely A side is without the gear teeth, for smooth structure, concrete it is to be understood that from the projection view of Fig. 5, side (namely near the side of wheel hub 2 side) on the right side of the whole gear teeth 4 does not necessarily have the gear teeth 4 to cover, in addition, the gear teeth 4 can cover on the left of wheel rim 1 Anywhere, this kind of structure is beneficial to the use in particular circumstances of this wheel.As a preferred mode, what needs ensured is the gear teeth 4 concrete shape is beloid, i.e. narrower compared with its rear part foremost at the gear teeth 4, so that the gear teeth 4 utilize narrow end above the crops in front separately in the process with whole vehicle wheel rotation, play the effect being similar to seedling distributing device.When adopting this kind of wheel, as it is shown in figure 1, mud-scraping apparatus 8 is arranged on the side that wheel covers without the gear teeth.
It should be noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
