The antiskid feet, which are sheathed in the antiskid foot sleeves, can freely slide by sliding fit with the thread sleeves to generate a high-performance antiskid effect. The utility model has the advantages of reasonable design, simple structure, high antiskid performance, safe application, noiselessness, little possibility to damage roadway and convenient assembly and disassembly.

Description

Automobile safety antiskid device

The utility model relates to the safe anti-skid device of a kind of automobile, and it belongs to automobile component.

Northern China has very long winter, the Northeast especially, and the time that ice and snow covers highway reaches six months unexpectedly, and this finds oneself in the mire road transport, and the traffic accident that causes thus is of common occurrence.The traffic department that has takes on automobile back wheel to twine the iron chain non-skid feature, but install complicated, the easy slippage reliability of iron chain is low, dangerous, and iron chain twine irregular, influence the outward appearance of automobile.

The purpose of this utility model is exactly to provide a kind of automobile simple in structure, easy to loading and unloading, that antiskid capability is high, safe and reliable safe anti-skid device.

The utility model is achieved in that

It is made up of main wheel 1, spring 2, non-slip feet 3 and silk braid 4.Main wheel 1 is that the agent structure of anti-skid device is a foundry goods, carries out artificial aging, and residual stress relieving is arranged with equidistant blind hole on main wheel 1 circumference, and the blind hole bottom is tapered, and this is anti-skidding footmuff 5.There is axis hole 6 at main wheel 1 center, and the size of axis hole 6 is corresponding with the vehicle wheel shaft size; Around axis hole 6 several screw holes 7 are arranged, the number of screw hole 7 is corresponding with the holding screw of vehicle wheel drum with size.Spring 2 is compression reseting springs, and the inboard that is contained in the positive stop lug boss 8 of non-slip feet 3 is thin foot lever 10 places, loses external force in non-slip feet 3 and does the time spent, with non-slip feet 3 release work.Non-slip feet 3 is main functional component of the present utility model, is cylinder, goes up thick (being thick foot lever 10), following thin (being thin foot lever 11), and there is a positive stop lug boss 8 the thickness junction, anti-skidding footmuff 3 running-fits on the external diameter of boss 8 and the main wheel 1; On the table body of thin foot lever 11 and positive stop lug boss 8, have a groove 9, discharge pressurized air when effect is compression, the thin end of non-slip feet 3, promptly thin foot lever 11, cover upper spring 2 inserts in the anti-skidding footmuff 5 again, can move along footmuff 5.Shape, the size of the inner structure of anti-skidding footmuff 5 and non-slip feet 3 adapt, and hollow has a circular channel 12, and an elongated passageway 13 is stretched out in its lower end.The port of anti-skidding footmuff 5 is equipped with a silk braid 4, silk braid 4 is spirally connected with anti-skidding footmuff 5, play a part locking non-slip feet 3, make from shoes 3 directed movement in anti-skidding footmuff 5, thereby the thick foot lever 10 running-fit open-work internal diameters of the open-work of silk braid 4 and non-slip feet 3 are less than positive stop lug boss 8.

Main wheel 1 radius of anti-skid device is in order to adapt to the contract change in radius of part of carload or scarce vapour hour wheel tire pressure less than the radius of automotive wheels, and with the anti-tamper anti-skid device, but the non-slip feet 3 of anti-skid device is when stretching out, and the radius of anti-skid device is greater than the radius of automotive wheels.

Service condition: when one of non-slip feet forms＜90 ° with the road surface in the automotive wheels rotation process, other other anti-skiddingly all form various angle with the road surface, like this, when automotive wheels is skidded, non-slip feet promptly rides on the road surface, with road surface shape at an angle; The radius that makes anti-skid device is greater than radius of wheel; Non-slip feet is little because of area, and unit area pressure increases friction coefficient and also increases thereupon, thereby plays the effect that prevents tyre skidding, as a same reason, automobile climbing, descending, can both prevent the landslide by actv. when side slope travels, and reaches skidproof purpose.

When do not slide in wheel and road surface, anti-skidding footmuff can be compressed, be entered to non-slip feet automatically, can not damage the road surface.

When automobile heavy duty or tire deflation,, 3-4 non-slip feet contact road surface can be arranged simultaneously, thereby antiskid capability strengthens more because contact ground-surface tire is compressed (when being 30cm with the road surface length of contact).

During use, respectively for two-wheel unloads, then descend foreign steamer as the back axle both sides, load onto safe anti-skid device, the wheel borehole jack that is about to safe anti-skid device is on wheel shaft, refill foreign steamer and get final product, when respectively being single-wheel, then unload wheel hub as the back axle both sides, load onto safe anti-skid device, the wheel borehole jack that is about to safe anti-skid device is aimed at the silk hole on wheel shaft, load onto wheel hub, and holding screw is twisted the jail.

Advantage of the present utility model:

1, reasonable in design, simple, easily manufacturing, cost is low;

2, antiskid capability height, safety, reliable;

3, dress is driven conveniently, and is practical;

4, noiselessness does not influence external sight;

5, do not damage the road surface.
