Description

Electrodeless gentle formula wheel

Technical field

The utility model relates to machine manufacture and auto parts and components field, is specially a kind of electrodeless gentle formula wheel that substitutes spoke with flat spring.

Background technology

The wheel rim of automotive wheel mainly adopts the hard spoke to be connected with the wheel between centers at present, and the hard bearing force to automobile is provided, and produces damping, buffering, transmission earth-grasping force, drag friction power by automobile tire.The tire bearing capacity of this form is not high, and the inner tube free tire is generally about 300 ~ 1000 kilograms; Be prone to blow out, sidewall is thinner, is prone to scratched by sharp object, and causes the serious accident accident thus; Because the tire wall is thinner, easy down the wearing out of exposing to the sun and rain, the life-span is shorter, and the life-span is about 1 year; All from tire and the anti-friction force of ground-surface, Tyte Wear is big for driving force; Be prone to skid when soft on the road surface, smooth.

Summary of the invention

The utility model provides a kind of simple in structure to the problems referred to above, and bearing capacity is bigger, the electrodeless gentle formula wheel that damping force is stronger.

The design plan of the utility model is following: electrodeless gentle formula wheel, form by solid tyre, wheel rim, flat spring group and wheel shaft.Wherein solid tyre constitutes by three layers, is respectively stressor layers, elastic rubber layer and wearing layer from inside to outside, and stressor layers is combined by fabric or steel wire, and the elastic rubber layer overlays on the stressor layers, and by the wearing layer parcel, wearing layer is synthetic by multiply cloth and rubber.Solid tyre snaps in the draw-in groove of wheel rim through stressor layers; On wheel rim negative camber and the wheel shaft positive camber protrusion rib is arranged; Be drilled with mounting hole on it; The draw-in groove at flat spring two ends is stuck in position with holes on protrusion rib and the protrusion rib on the wheel shaft positive camber on the wheel rim negative camber, and passes mounting hole with full dog point socket set and connect.Flat spring integral body is arc, and the curvature at two ends is bigger, and middle curvature is less, and two is provided with draw-in groove and rivet hole, and wheel rim is connected with a plurality of flat springs with the wheel between centers.

The utility model changes the spoke of tire in the wheel into be made up of many flat springs spring assembly, and main damping, the buffer action of tire are transferred on the spring assembly, and simultaneously spring assembly is also born in the past spoke to the bearing force of automobile.The arc flat spring can produce poultry ability process when receiving stretching, compression, and when replying original shape, can discharge the elastic potential energy that its poultry is deposited.

The utility model changes air tyre into solid tyre, bears vehicle weight and friction force that in transmission, braking procedure, produces and antagonistic force by solid tyre.The solid tyre innermost layer is the stressor layers that combines with the wheel exterior feature by fabric or steel wire binding layer, and it mainly acts on is that the stress biography of getting in touch between wheel and solid tyre connects; Interlayer is the elastic rubber layer, is in by in the outermost wearing layer parcel, and it plays the buffer action of wheel road pavement pressure, also plays cushioning effect simultaneously; Outermost layer is a wearing layer, and wearing layer is synthetic by multiply cloth and rubber, plays the friction force action and reaction power of bearing between automobile and the road surface, anti-skidding anti-wear effect.

The utlity model has following advantage:

1 because solid tyre does not have pneumatic tyre, does not exist and blows out, so solid tyre can increase the safety of tire; Do not have pneumatic tyre, its anti-aging breakage-proof ability is also corresponding significantly to improve the service life of having improved solid tyre.

2 wheel bearing capacities increase, and can change the intensity of flat spring and arbitrarily design the theoretical bearing capacity of wheel, can reach easily more than 1000 kilograms.

3 are beneficial to the flattening trend of wheel, to increase the earth-grasping force and the friction force of wheel, make the handling raising of vehicle.

4 because the change of car wheel structure has just changed the driving force pattern of wheel; Except with the earth-grasping force and friction force that firmly utilize tire; Electrodeless gentle formula car wheel structure has also utilized the weight of automobile itself that flat spring is raiseeed can; And when wheel, discharge again, can increase the driving force of automobile, the acceleration capacity of automobile is improved; Vehicle no longer includes expenditure of energy under steam and in tire, compression of air is done work; To sum up some can energy efficient 5%～12%.

5, when automobile brake, can absorb a part of kinetic energy, prevent wheel lockup and reduce stopping distance by spring; Owing to the flexibility effect of spring assembly, significantly improved the damping effect of wheel.
