With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings:
Embodiment 1
As shown in Figure 1 to Figure 3, a kind of running gear described in this utility model embodiment, including at least one wheel, specially include 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 means, running gear of the present utility model is without driven pulley, support whole vehicle frame 7 to replace driven pulley and follow drivewheel advance, running gear of the present utility model provides at least one supporting leg 6, in the case of meeting whole mechanically stable, running gear of the present utility model 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 supporting leg 6 around the vertical axis 360 ° rotation of 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, on the basis of stating purpose in realization, the wheel of running gear of the present utility model and the combination of supporting leg 6 structure are diversified, such as: use the combination of two supporting legs 6 of a wheel;Use the combination of one supporting leg of two wheels;Use the combination of a multiple supporting leg of wheel 6;Use the combination of two multiple supporting legs of wheel 6;Using the combination etc. of the multiple supporting leg of multiple wheel 6, even if all using car wheel structure, the effect that this utility model is walked 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, referring specifically to shown in accompanying drawing 3, it can be seen that the running gear described in the present embodiment is when straight ahead, each wheel is located along the same line with the movement locus of the supporting leg 6 that its front and back position is arranged.Further, running gear described in the utility model is additionally provided with mud-scraping apparatus 8.
Embodiment 2
Such as Fig. 4 and Fig. 5, as a preferred mode, present embodiments providing preferably a kind of wheel of this utility model, 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 axis of wheel hub 1 and the dead in line of 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 wheel of the present utility model, 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 two or more gear teeth 4 it are additionally provided with on wheel of the present utility model, all gear teeth 4 are arranged on wheel rim 1, and along the even circumferential distribution of wheel rim 1, it is characterized in that wheel described in the utility model 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, shown in i.e. diagram A, position is without covering, i.e. A side is without the gear teeth, for smooth structure, concrete it is to be understood that in terms of the projection view of Fig. 5, side (i.e. 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, need ensure be the gear teeth 4 concrete shape be 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 during with whole vehicle wheel rotation, play the effect being similar to seedling distributing device.When using 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 the technical solution of the utility model, it is not intended to limit;Although this utility model 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;And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
