Abstract

The invention provides a non-inflated wheel. An inner steel rings is sleeved by two outer steel rings which are the same in structure and opposite in position, a fixed steel ring is added, and therefore a combined steel ring is formed; a plurality of evenly-distributed fixing holes are formed in the wall of the inner ring; the outer steel rings on the two sides form an inverted-T-shaped annular groove respectively, and the grooves are used for fixing rubber side seals. Each elastic special-shaped spoke is formed by connecting an upper deforming semi-arch long steel sheet and a lower deforming semi-arch long steel sheet; each arch top is provided with a plurality of fixing holes; and two sides of each arch top stretch out to form a plurality of sets of damping pieces. A plurality of evenly-distributed fixing holes are formed in the walls of cylindrical elastic steel rings; and the elastic steel rings are embedded on the inner wall of the combined rubber ring. Rubber outer rings and the rubber side seals on the two sides are of connection structures; the inner rings of the rubber side seals are each provided with a T-shaped annular rubber fixing ring. Components are fixedly connected through square-head fixing bolts and round-head fixing bolts. A structural body of the non-inflated wheel has the excellent elasticity; the non-inflated wheel cannot blow out; the wheel can be designed according to the ideal flatness ratio; the manufacturing cost is low; and the load capability is large.

Description

Non-aeration wheel

Technical field

The present invention relates to field of mechanical technique, specifically a kind of vehicle wheels in the vehicle.

Background technology

Now, air tyre wheel is widely used on self-propelled vehicle due to elastic shock attenuation function excellence, but there is many fatal defects: (1) easily blows out; (2) be difficult to reach desirable flat ratio; (3) manufacturing cost is high; (4) load-bearing capacity is on the low side.According to statistics, in the traffic accident that China Expressway occurs, 70% is had to cause owing to blowing out, in addition flat ratio is higher because pursuing comfortable for air-inflation tyre, little with ground friction face, tyre last reduces, and thus causes very large economic loss even personal injury to society.Although, there is many fatal defects equally, be difficult to meet desirable technical requirements in other various wheel mutual characteristic.

Summary of the invention

The object of the invention is to overcome the defect that existing self-propelled vehicle air tyre car wheel structure exists, a kind of self-propelled vehicle non-aeration wheel of brand new is provided.The present invention plays rubbing effect by rubber outer ring and earth surface, the flexible steel ring being embedded in combination rubber ring inner headed face is relative fixing with elasticity abnormity spoke, jointly complete pressure-bearing, damping and support function, and play a part to connect, fix rubber outer ring and combination steel ring.This non-aeration wheel structure not only possesses excellent resilience equally, and can not burst, and can design by desirable flat ratio, manufacturing cost is less, and load-bearing capacity is large, can overcome the shortcomings of existing wheel.

Technical scheme

The concrete technical scheme of non-aeration wheel is, combination steel ring cylindrical wall evenly fixes multiple elasticity abnormity spoke in circumferential direction through square toes gim peg, elasticity abnormity spoke is fixedly embedded in the flexible steel ring in combination rubber ring inner round wall by round end gim peg, embedded in the T-shaped ring groove of combination outer ring, steel ring both sides by the rubber mounting ring on rubber side seal inner edge in combination rubber ring again, form a sealing non-aeration wheel.

Combination steel ring comprises interior steel ring, outer rim and mounting ring.The edge of the hollow side of interior steel ring has one to the annular groove of inner opening.Interior steel ring cylindrical wall is uniformly distributed multiple fixed orifice.Outer rim one side outer rim has an outwardly open annular groove.Outer rim cylindrical wall is uniformly distributed multiple fixed orifice.On interior outer rim, the geometry sizes of fixed orifice is identical, and quantity is equal, and position correspondence is coincide.Mounting ring outer rim has one to the annular groove of inner opening, has multiplely fixedly use circular hole near endoporus surrounding.Elasticity abnormity spoke is formed by the long steel disc disjunctor of semi-arched of upper and lower two distortion, and its vault respectively has multiple fixed orifice, and dual-side stretches out many groups gradually flat arc-shaped shock-absorbing sheet, and the connection support end often organizing vibration damping sheet outside is all an entirety.Flexible steel ring wall is uniformly distributed multiple fixed orifice.The outer ring of combination rubber ring is tubular rubber outer ring, and there is ring-shaped rubber side seal both sides, and rubber side seal has T-shaped rubber mounting ring near inner ring, and rubber outer ring and rubber side seal are the integral structures that is connected.Square toes gim peg tightening latch one end is cuboid bolt head, and the other end is special-shaped bolt cap, and respectively there is a protruding locking head at bolt cap two ends, and round end gim peg tightening latch one end is cylindrical bolt head, and the other end is a special-shaped bolt cap, and respectively there is a protruding locking head at bolt cap two ends.

Outer rim is enclosed within interior steel ring from interior steel ring side.It is facilitate installation to put into needs that gim peg on combination steel ring is designed to square toes.Gim peg is put into by tightly after fixed orifice, and then rotated ninety degrees angle, allows the locking head at two ends snap in the inwall locking hole of interior steel ring, reaches effect elasticity abnormity spoke is fixed on combination steel ring.Round end gim peg is then the fixed orifice putting into flexible steel ring in advance, and flexible steel ring is as skeleton and the one-shot forming of combination rubber ring.When elasticity abnormity spoke and flexible steel ring connection, round end can facilitate gim peg to rotate.During installation, on gim peg, locking head is also by tight rear rotated ninety degrees angle, and on bolt cap, the locking head at two ends snaps in elasticity abnormity spoke inwall locking hole.Combination steel ring dual-side has two inverted T shape annular grooves, and the rubber mounting ring sealed up by rubber side is embedded in groove and plays fixing rubber side seal, and such foreign debris can not enter in elasticity abnormity spoke, can also reduce the oxidizing action of air.Elasticity abnormity spoke and flexible steel ring are connected to form a solid and reliable entirety by gim peg, jointly complete damping and support function.Rubber outer ring relies on flexible steel ring to do skeleton, plays support rubbing effect, gives full play to respective premium properties.The shape of elasticity abnormity spoke is very beneficial for the design needs of wheel lower flat-ratio.

The non-aeration wheel that the present invention proposes, explosion can be avoided, solve the difficult problem that air tyre wheel flat ratio is not high very well, substantially increase load-bearing capacity, there is excellent elastic shock attenuation function, stabilized structure, can be widely used in the configuration of all kinds of vehicle wheels, be the innovation to existing wheel technical field.
