Description

Combined type automobile rubber antiskid chain

Technical field

The utility model relates to a kind of improvement of vehicle limited slip device, especially a kind of combined type automobile rubber antiskid chain, and it is widely used in the hauling operation field.

Background technology

In long area of freezeup period, winter vehicular communication transport anti-skidding problem continue to use always chain twine cover be defined in carry out on the tire skidproof.This non-skid feature is settled relatively to waste time and energy, and during vehicle ', the lame severity of running, noise are big, and damage tire and road surface.This winding cover is difficult for fixation, often takes off chain, loosening, so that get rid of chain, its antiskid capability is relatively poor, and especially slip resistance can be poorer, can't use especially for wagon.Also have a kind of rubber antiskid device, the rubber antiskid piece that its spacing is bigger is tied a whole set ofly and is contracted on tire and spoke centre.The center constriction device of this device, the spoke decorated disk of wagon can seriously wear and tear, this device is torn when damaging in that certain piece is anti-skidding, can't change nonslipping spur, can only scrap by package unit, cause unnecessary waste, the nonslipping spur mechanical strength of this device is not enough, and it is tear-resistant, impact resistance is poor, especially is unable to undergo the impact that the force of inertia that is produced is braked in emergency brake, take off cover and tear leg, so that cause the accident.Present in addition articulated Antiskid chain cover, though connect to form by a plurality of movable joints, but complex structure more owing to adopted the square coupling link, makes the articulated Antiskid chain cover can't folding storage, can only dismantle collection, waste time and energy, the anti-skidding steel nail of appearing is the one-step casting moulding, can't change after the wearing and tearing, can only cancel by whole Antiskid chain cover, use cost is too high.

Summary of the invention

The purpose of this utility model is the defective that will solve above-mentioned anti-skid device, designs a kind of later-model combined type automobile rubber antiskid chain.This anti-slipping chain can adapt to various freeze-up, ice and snow and mire, rainwater ground-surface vehicle ', and antiskid capability is good repeatedly for it, and shock resistance, low noise, nothing top be lame, do not damage the road surface, and the wheel spoke dish does not does not wear and tear.This Antiskid chain cover, simple in structure, intensity is big, overlapping easy to break is hidden, and easily changes parts, the spacing of each non-skid slip knot of scalable, new used tire all can use.Especially replaceable anti-skidding ailhead, the mechanical strength of major part will be strengthened, with superior good antiskid capability.

The purpose of this utility model is achieved in that it includes non-skid slip knot that is distributed on the wheel tyre outside face and the crab type butt hook that is connected all this non-skid slip knot chainings, and described crab type butt hook is hung the inboard head and the tail annulus that is hinged in adjacent non-skid slip knot by fix screw and constituted inner cover chain; Described crab type butt hook is hung to be hinged by fix screw and is constituted the outer cover chain in the outside of adjacent non-skid slip knot head and the tail annulus; Link up with successively respectively in the drop-down plate hook of all non-skid slip knot outer cover chains by the link on it by the elastic tightening circle again, tighten up the combined type automobile rubber antiskid chain that covers on admittedly on the tire thereby constitute; On the landing ground of non-skid slip knot, be provided with and arrange the orderly anti-skidding opening of triangle and arrange the orderly steel nail of appearing.

Described non-skid slip knot, fastened inboard head and the tail annulus on its inboard head and the tail drop ear, be installed with outside head and the tail annulus on its outside head and the tail drop ear, between two on each non-skid slip knot inboard head and the tail drop ears, be hinged with chain link, between two on each non-skid slip knot outside head and the tail drop ears, be hinged with shackles ring with drop-down plate hook.

The described steel nail of appearing is made up of ailhead, holding screw and nail seat, and wherein ailhead is tightened in the nail seat by holding screw.

Described ailhead and holding screw are one.

Described elastic tightening circle is a ring shape, passes through hollow out interruption-forming twice reinforced rib between its central cores circle and the outer hanging ring.

Because the utility model has adopted said structure, compared with prior art have and to adapt to various freeze-up, ice and snow and mire, rainwater ground-surface vehicle ', antiskid capability is good repeatedly for it, and shock resistance, low noise, nothing top be lame, do not damage the road surface, and the wheel spoke dish does not does not wear and tear; This Antiskid chain cover, simple in structure, easy to use, tightening ring has adopted the dual link muscle, and intensity is bigger, by adjustable butt hook, the spacing of each non-skid slip knot of scalable, new used tire all can use, and the collection of folding easily back; Easily change parts, especially adopted replaceable anti-skidding ailhead, make with antiskid capability better.In case the structural advantages of combined anti-skid chain is that also certain non-skid slip knot accidental damage is replaceable, can not cause integral body to scrap.
