CN2135489Y - Folding convex skid proof caterpillar for automobile - Google Patents

Abstract

The utility model provides a folding convex skid proof caterpillar for automobile, which is a flexible connection device composed of a plurality of skid proof blocks connected in series. The skid proof blocks are provided with racks. While in use, the caterpillar is sheathed on the back wheel of the automobile to inlay the convex parts of the skid proof blocks into the interstice between two tyres of the back wheel, making the whole caterpillar be fixed by tightening a screw rod on the contact point of the two ends of the caterpillar. The automobile mounted with the utility model can effectively run on various road surface easy to skid, such as the snow and ice ground, the mire, the depression, etc.

Description

Folding convex skid proof caterpillar for automobile

The utility model relates to the folded formula convex skid track of a kind of automobile, and it is monolateral for two-wheel vehicle rear drive sprocket to be applied to rear drive, is applicable to ice-snow field, various Slippery roads such as mire, depression.

Existing rubber tire automobile when travelling at ice-snow field, when marshy area and sand ground, often is absorbed in owing to skidding and can not extricate oneself.Solution to this problem is to add anti-skid device on tire.Existing chain rail crawler type anti-skid device, though have good skidproof effect, because of its manufacturing process complexity, heaviness, not quick detachable and maintenance etc., thereby be restricted using to promote.Characteristics such as the chain-type anti-skid device portably uses conveniently though have, and cost is low, often the not dark skidproof effect of mud layer is relatively poor because of chain is eaten into when the road shape is relatively poor, and influences tire life because of the tire compression face diminishes.

It is a kind of improved that the utility model purpose is to provide, and is used for fixing the crawler type anti-skid device at the automobile rear drive sprocket, and it is simple that it not only has manufacturing process, dismounting, installs easy to carryly, also can protect tire, prolongs the used life of tire.

The utility model is achieved in that

The vehicle skidproof crawler belt that is proposed is by the soft folded formula device that is connected into of coupling link by polylith convex nonslipping spur.Nonslipping spur is through the moulding of washing one's face by cast steel one-step casting or punching press.The nonslipping spur convex surface of moulding leaves connecting bore, between nonslipping spur and the nonslipping spur is to be connected into crawler type by connecting bore by 3 one group coupling link.The nonslipping spur stage casing is a convex, and size just can be inlayed admission back wheels of vehicle two tire gaps.The anti-skidding leaf length that extend the nonslipping spur both sides equals the tire plane of structure, thickness 5-15 millimeter.Anti-slide plate and tire contact surface are cast arc, connect face so that coincide.The anti-slide plate back side is landing ground, on have three to be inverted the equicrural triangle anti-slop serrations.In order to prevent that skid track and tire are beaten interior cunning in use, stamp point-like or strip fried dough twist in all and tire contact site when making nonslipping spur, sliding/friction coefficient in increasing, it is upright that respectively there is the connecting bore of a nonslipping spur at the skid track two ends, during use, skid track is put along automobile back wheel is whole, pass connecting bore with the screw rod that is with helical spring, fastening nut can use.

The utility model unloads the collapsible placement in back because be by coupling link nonslipping spur to be connected into crawler belt and by the screw of tightening on the joint connecting bore whole piece crawler belt is fixed on the automobile back wheel, and is therefore simple in structure, easy to carry, and loading and unloading easily; When certain damage parts, only need change corresponding component and get final product, therefore easy to maintenance; Simultaneously because whole crawler belt and the fragile greatly and not tire of tire contact surface, and can eat into darker mud layer because of anti-slop serrations and improve skidproof effect.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the convex skid track birds-eye view that has reduced nonslipping spur.

Fig. 2 is the front elevation of Fig. 1.

Fig. 3 is the left side view of Fig. 1.

Fig. 4 is the right side view of Fig. 1.

Among the figure: 1, anti-slide plate, 2, the triangle anti-slop serrations, 3, projection, 4, connecting bore, 5, coupling link, 6, upright connecting bore, 7, twisted shape, 8, screw rod, 9, the helical spring cover.

The nonslipping spur of cast steel one-step casting or drawing is by trapezoidal protruding 3, form along the anti-slide plate 1 that exterior is extended, 10 millimeters of anti-slide plate thickness, landing ground is cast with del anti-slop serrations 2, cast arc with the tire contact surface, radius equates that with tire radius cambered surface and projection and tire contact surface are cast with point-like fried dough twist 7, prevent interior cunning so that increase internal friction coefficient in use.There is connecting bore 4 the projection bottom surface, 125 millimeters in aperture.By 15 groups, every group of three coupling link 5 hole that is connected in series forms every secondary crawler belt by 16 nonslipping spurs.Coupling link is to be processed into toroidal by foundry goods or steel, and material diameter is 10 milli material, and the circle interior diameter is 22 millimeters after the moulding.Be cast with vertical type connecting bore 6 on the nonslipping spur convex at every secondary crawler belt two ends, 1250 millimeters in aperture.During use, crawler belt is encased the automobile back wheel tire, make projection partly inlay the into gap between two tires, make crawler belt be connected into ring with Luo bar 8.Crawler belt shifts forward during for fear of vehicle ', can put Luo spring cover 9 on screw rod 8, plays buffer action.

When being embodiment with 900 type tires, more than the dimensions of the folded formula skid track that proposed be: whole long 500 millimeters of nonslipping spur, thickness 10 milli material, protruding bottom surface is wide 40 millimeters, long 110 millimeters of both sides.125 millimeters of connecting bore diameters.195 millimeters of anti-skidding lengths of a film, wide 120 millimeters.15 millimeters of equicrural triangle anti-slop serrations two length of sides, 30 millimeters of bottom side lengths, adopting the Luo bar is 12 * 75 millimeters, Luo spring cover is 12 * 75 millimeters a gauge member.

Claims (5)

1, a kind of automobile crawler belt anti-skid device is characterized in that crawler belt is to include the nonslipping spur of preventing slide plate 1, triangle anti-slop serrations 2, projection 3 by polylith to be connected into the folded formula anti-skid device that is flexible coupling by connecting bore 4 by coupling link 5.

2, device according to claim 1 is characterized in that this device can be that every group of 3 coupling link formed by the identical nonslipping spur of 16 block sizes and 15 groups.

3,, it is characterized in that described nonslipping spur thickness is the 5-15 millimeter according to claim 1,2 described devices.

4, according to claim 1,2,3 described devices, two tire gaps are as the criterion just to inlay into to it is characterized in that nonslipping spur projection 3 sizes.

5, device according to claim 1 is characterized in that putting on the Luo bar of joint, skid track two ends Luo spring cover 9.
