Detailed Description
The present invention will be further described with reference to the accompanying drawings.
A bearing type mechanically resilient wheel, as shown in fig. 1-2, includes a wheel, a set of hinges, and a hub plate. The wheels include rubber layers, elastic rings and snap rings as shown in figures 3-4. The elastic ring parallelly penetrates through the through hole in the clamping ring to form a tension pulley framework; the lower end of the clamping ring is provided with a pin lug; the outside cladding of elastic ring has the rubber layer, and the wheel is installed with the wheel hub coaxial. As shown in fig. 5-6, the snap ring structure employed in the embodiments of the present invention includes a plurality of through holes and pin ears. The number of the through holes is the same as that of the elastic rings and is at least 5. In the invention, the number m of the snap rings is 15, the number n of the elastic rings is 5, and the thickness of the flexible wheel is far smaller than the radius of the wheel. The upper part of the snap ring is attached to the inner wall of the rubber layer and is wrapped by rubber together with the elastic ring.
Evenly be equipped with a plurality of hinge group between the wheel of the packing and the wheel hub dish, every hinge one end and snap ring lower extreme fixed connection in the hinge group, the other end and wheel hub dish fixed connection. As shown in fig. 10-11, the hub disk includes a front disk and a rear disk; the two hub plates fixedly clamp the hinge group in the middle; the front disc and the rear disc are correspondingly provided with a plurality of circular through holes;
as shown in fig. 7-9, the upper end of each hinge in the hinge set according to the embodiment of the present invention is fixedly connected to the pin lug at the lower end of the snap ring through a bearing and a pin; the bearing outer ring is embedded into the pin lugs, and the pin shaft sequentially penetrates through the pin lugs at two sides and the bearing inner ring to fixedly connect the hinge and the clamping ring; the middle part of each hinge is connected with an upper section and a lower section through a bearing, and a pin shaft is fixed on the inner ring of the bearing; the front disc and the rear disc of the hub disc are oppositely provided with bearings at circular through holes, the outer ring of each bearing is fixed with the hub disc, the inner ring of each bearing is fixed with a pin shaft, the pin shafts penetrate through the through holes at the lower ends of the hinges to fixedly connect the hinges with the hub disc, and the two ends of each pin shaft are fixedly connected through bolts and further axially fixed. The bearings adopted by the invention are all tapered roller bearings, and a shaft shoulder is reserved on the pin shaft so as to realize the axial positioning of the bearings.
During motion, ground impacts are transmitted to the hub via the gradual attenuation of the wheel-hinge set-bearings, which primarily bear the lateral and radial forces to which the wheel is subjected. By adopting the bearing connection mode, the hinge movement process is smoother, and the driving smoothness is improved.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
