Description

The heavy motor vehicle anti-skid device

Technical field

The utility model relates to anti-slip device for automobile, particularly a kind of heavy motor vehicle anti-skid device.

Background technology

In the winter time, be easy on the road be covered, cause motor tire and ground-surface friction coefficient to reduce, very easily cause automobile tyre slip get out of hand and cause traffic accident in the process of moving by ice and snow.Particularly for the tire that heavy motor vehicle assembled, because that it is subjected to is heavy bigger, tire is more prone to skid, break away at ice and snow, heavy road face straight-line travelling and when turning round, and is dangerous higher.Traditional antiskid device for tyre is an anti-slipping chain, during use it directly is bundled on the circumferential outside face of tire, and it is not firm that this kind anti-slipping chain cooperates with fitting of tire, and easily with the tire disengaging and be thrown out of, danger is bigger when the automobile fast running; Also has a kind of improved cross-track tyre chain in addition, comprise that many are covered in the chain of motor tire outside face and the connecting strand that the tire both sides connect each chain ends, during use it is sleeved on the motor tire outside face, existing anti-slipping chain is applicable to that all the lilliput car fitting of tire use, when being used for then existing installation to cooperate shortcomings such as not firm, fragile, that dismounting is inconvenient, skid resistance is bad when tyre of heavy truck is anti-skidding.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of install cooperate firm, load-bearing property better, not fragile, be easy to dismounting and the good heavy motor vehicle anti-skid device of antiskid capability.

The utility model solves its technical matters and takes following technical scheme to realize:

This heavy motor vehicle anti-skid device, it is characterized in that: constitute by terminal pad, connection pawl, anti-slide plate, anti-slipping chain, terminal pad is installed on the sidewall of tyre rim skeleton, the terminal pad radial equipartition is shaped on the connection pawl, anti-slide plate end is installed on and connects in the plug-in opening that pawl axially is shaped on, and is connected with anti-slipping chain between anti-slide plate and the adjacent anti-slide plate.

And described anti-slide plate end is installed on and connects in the plug-in opening that pawl axially is shaped on, and stretches out the end that connects pawl at anti-slide plate and adopt nut to install.

And described anti-slide plate is a hook solid, is shaped on staggered concavo-convex anti-slideway on the outside face of anti-slide plate ground terminal.

And, on the terminal pad card of described connection pawl end, be shaped on safe positioning table.

And the steel ring skeleton of described terminal pad and motor tire is solidly installed by circumferential isometrical uniform bolt.

And the anti-slipping chain between the described adjacent anti-slide plate is the 1-5 bar.

And described anti-slipping chain is that the cross section is square square steel chain, and the screw that this square steel chain is installed by its end is installed in the made tapped bore of anti-slide plate side.

Advantage of the present utility model and good effect are:

1. the terminal pad of this anti-skid device can directly be installed on the steel ring skeleton of motor tire by bolt, thereby make the integral body of this anti-skid device safer reliable with combining of motor tire, terminal pad be connected pawl and can adopt the mode of the special-purpose material integrally casting of tyre rim skeleton moulding to process, strengthening the bearing of anti-skid device, but long-term use and not fragile.

2. the terminal pad of this anti-skid device is fixed with a plurality of anti-slide plates that clamp outer surface of tire by the uniform connection pawl that is shaped on of its periphery, and stretch out the end that connects pawl at anti-slide plate and adopt nut to install, when running car, anti-slide plate can be held the outside face that fits in tire tightly, the suffered pressure of surface of tyre is more even, reduced vibration, automotive operation is more steady, noiseless.

3. on the terminal pad card that connects the pawl end, be shaped on safe positioning table, the end roof pressure of anti-slide plate was on this safe positioning table when tire was sunken but automobile is blown out suddenly, anti-slide plate can play certain supporting role to vehicle body, prevents automobile roll and causes traffic accident.

4. anti-slide plate surface is shaped on staggered anti-slideway, and this anti-slideway has increased the friction coefficient between tire and the ground, and makes tire all preferable at the antiskid capability of all directions.

5. connect by anti-slipping chain between the adjacent anti-slide plate, and can connect many anti-slipping chains, under action of centrifugal force, produce distortion and the disengaging surface of tyre to prevent anti-skidding; And this anti-slipping chain is that the cross section is square square steel chain, also produces certain skidproof effect.

Reasonable, the load-bearing property of the utility model scientific structure design better, not fragile, install cooperate firm, be easy to dismounting, have good antiskid capability, be applicable to the anti-skidding of tyre of heavy truck.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

The innovative point of this heavy motor vehicle anti-skid device is: be made of terminal pad 2, connection pawl 5, anti-slide plate 3, anti-slipping chain 13, terminal pad is installed on the sidewall of steel ring skeleton 10 of tire 1, and the steel ring skeleton of terminal pad and motor tire is solidly installed by circumferential isometrical uniform bolt 6.The terminal pad radial equipartition is shaped on the connection pawl, terminal pad be connected pawl and can adopt the mode of integrally casting moulding to process, strengthening the bearing of anti-skid device, but long-term use and not fragile.Anti-slide plate end is plugged in the plug-in opening that connects pawl and axially be shaped on (among the figure not label), and stretch out the end that connects pawl at anti-slide plate and adopt nut 7 to install, can be only in the time need not using anti-skid device with prevent slide plate pull down can and need not terminal pad is pulled down, simplified installation, unloading process.On the terminal pad card that connects the pawl end, be shaped on safe positioning table 4, but when automobile blow out suddenly tire when sunken the end roof pressure of anti-slide plate locate safely at this, anti-slide plate can play certain supporting role to vehicle body, prevents automobile roll.Anti-slide plate is a hook solid, on the outside face of anti-slide plate ground terminal, be shaped on staggered concavo-convex anti-slideway 8, should comprise vertically anti-slideway and the laterally anti-slideway that many groups are staggered by anti-slideway, should vertically anti-slideway and laterally anti-slideway can prevent effectively that motor tire fore-and-aft direction and side direction from skidding, also be shaped on reinforced rib 11 at anti-slide plate bending part.Be connected with anti-slipping chain between anti-slide plate and the adjacent anti-slide plate, anti-slipping chain between the adjacent anti-slide plate is the 1-5 bar, shown in the present embodiment is to be connected with two anti-slipping chains between the adjacent two anti-slide plates, anti-slipping chain is that the cross section is square square steel chain, this square steel chain also has certain skidproof effect, and the screw 12 that this square steel chain is installed by its end is installed in the made tapped bore 9 of anti-slide plate side.Anti-slide plate and anti-slipping chain interconnect and are coated on the contacted surface of tire and ground, have bigger anti-skidding area, and safe and reliable, and surface of tyre stressed more even vibrates lessly, makes automotive operation more steady.
