Abstract
The invention discloses a ram-type composite pedrail wheel and aims at providing a ram-type composite pedrail wheel which is simple in structure, convenient to process, light in weight and good in reliability. The ram-type composite pedrail wheel comprises a disc-shaped spoke, wherein a positioning hole and a connecting hole for connection of the spoke and a drive shaft is formed in the center of the spoke. The ram-type composite pedrail wheel is characterized in that multiple V-shaped connecting frames perpendicular to the end faces of the spoke are respectively distributed and fixed on the peripheries of two end faces of the spoke, the V-shaped bottoms of the connecting frames expose out of the outer edge of the spoke to form a positioning gear, the positioning gear is a circumscribed circle with the positioning hole as the center, an annular flexible pedrail is wrapped on the positioning gear, and the inner surface of the pedrail is provided with a groove matched with teeth on the positioning gear, and the pedrail is connected with the positioning gear through the groove. The spoke and the connecting frames can be formed through cold impact molding, and the production efficiency is higher than that of traditional drive wheels or pedrails. In addition, the manufacture cost is low. The ram-type composite pedrail wheel is simple in structure and light, and great convenience is brought for installation and usage of the wheel.
Description
Technical field
The present invention relates to wheel, particularly a kind of punching type composite crawler wheel.
Background technology
Crawler belt, as the actuating device of vehicle, due to advantages such as its ground contact area are large, and specific pressure is little, and adhesive ability is large, is used widely on the equipment such as tank, large tractor, large-scale forklift, bulldozer.But caterpillar drive complex structure, needs crawler belt, drive wheel, caterpillar wheel, tension wheel and tightening device etc., and poor reliability, need frequent care and maintenance, whole heavy, processing and installation trouble, manufacturing cost and use cost are high.
Summary of the invention
The object of this invention is to provide punching type composite crawler wheel a kind of simple in structure, easy to process, lightweight, good reliability.
In order to reach above-mentioned requirements, punching type composite crawler wheel is achieved through the following technical solutions: it includes the spoke of dish type, the center of spoke is shaped with for the knock hole and the connecting bore that are connected with axle drive shaft, it is characterized in that being fixed with a plurality of V-arrangement link spans vertical with spoke end face the surrounding of spoke both ends of the surface is uniform respectively, the outer rim that spoke is exposed in the bottom of link span V-arrangement forms Positioning Gear, and this Positioning Gear is the circumscribing circle centered by knock hole, on Positioning Gear, be enclosed with annular flexible pedrail, the inside face of crawler belt be shaped with Positioning Gear on the groove that matches of the gear teeth, by groove, crawler belt is connected with Positioning Gear.
On two joint faces of described link span, be shaped with outside flange, be shaped with link span fixed orifice on flange, link span is by bolt, and the spoke fixed orifice on link span fixed orifice and spoke, connects the link span in spoke both ends of the surface.
In the middle of the groove at two ends, be provided with location convex tendon, the surface being connected with spoke in the bottom of link span V-arrangement is shaped with breach, and breach is stuck on the convex tendon of location, to limit moving axially of spoke and crawler belt.
Described flexible pedrail is rubber belt track.
Each anti-slop serrations of described its outside face of flexible pedrail is distributed between each groove.
On described spoke, be fixed with altogether 16-24 link span.
The punching type composite crawler wheel of manufacturing according to such scheme, its spoke and link span all can be by cold stamping shaped acquisitions, and production efficiency is more much higher than conventional drive wheel or crawler belt, and low cost of manufacture.This car wheel structure than before support rack type triangle composite crawler wheel more simple, light, for the installation of wheel, travelling brings great convenience.And each anti-slop serrations outside crawler belt is distributed between each groove, makes to utilize under steam the elastic deformation of crawler belt, outer rim ground contact area is wheeled larger than common, has improved the adhesive ability on it and ground, is more conducive to bring into play the effective power of locomotive drive.This patent can be for equipment such as large-scale agricultural machinery, forklift, bulldozers, can pitchy highway, snowfield, sand ground, mud ground, meadow, hollow etc. travel on various ground, applicability is wide.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 to Fig. 6 is the structural representation of punching type composite crawler wheel, as seen from the figure, it include with steel plate stamping, be pressed into dish type spoke 1 as Fig. 7, shown in Fig. 8, the center of spoke 1 is shaped with for the knock hole 2 and the connecting bore 3 that are connected with axle drive shaft, the surrounding of spoke 1 both ends of the surface respectively uniform 10 of every sides (totally 20) V-arrangement link span 4 vertical with spoke 1 end face that be fixed with as Fig. 9, Figure 10, Figure 11, shown in Figure 12, the outer rim that spoke 1 is exposed in the V-arrangement bottom of link span 4 forms Positioning Gear, and this Positioning Gear is the circumscribing circle centered by knock hole 2, on Positioning Gear, be enclosed with annular rubber belt track 5, the inside face of crawler belt 5 be shaped with Positioning Gear on 10 grooves 7 matching of the gear teeth 6, with relatively rotating of restriction crawler belt 5 and spoke 1, in the middle of the groove 7 at two ends, be provided with location convex tendon 8.On two joint faces of link span 4, be shaped with the flange 9 of outside bending, on flange 9, be shaped with 4 link span fixed orifices 10, link span 4 is connected the link span 4 in spoke 1 both ends of the surface with the spoke fixed orifice 12 on spoke 1 through link span fixed orifice 10 by bolt 11, the surface being connected with spoke 1 in the V-arrangement bottom of link span 4 is shaped with breach 13 as shown in Figure 10, Figure 12, and breach 13 is stuck in moving axially with restriction crawler belt 5 and spoke 1 on the convex tendon 8 of location.Each anti-slop serrations 14 on crawler belt 5 outside faces is evenly distributed between each relative groove 7.Utilize under steam the own wt of locomotive and the elastic deformation of crawler belt 5, crawler belt 5 is contacted with ground one-tenth face, (wheel is circular conventionally as shown in figure 13, it is that line contacts with ground in theory), make outer rim ground contact area than wheeled large of common rigidity, the adhesive ability that has improved it and ground, makes caterpillar wheel be not easy to skid and sink, and has improved the ability of creeping and the crossing ability of vehicle.
