A series of anti-skid devices can be manufactured according to different type of motor vehicles.

Description

Anti-skid device for motor vehicle wheel

The utility model wheel for motor vehicle anti-skid device is power actuated vehicle used vehicle wheel non-slip instrument when travelling on ice and snow road winter.

In the winter of severe cold,, ice and snow cause the road sliding owing to having covered the road surface.Because the road is sliding, not only the highway communication transportation is subjected to certain influence, and also generation constantly of various types of traffic accident, has caused certain infringement to the development of the national economy.

The purpose of this utility model is in order to guarantee the safety of highway communication transportation in winter, for power actuated vehicle winter anti-skidding provides a kind of safe and reliable vehicle wheel non-slip device.

At present, both at home and abroad the non-skid feature in winter for self-propelled vehicle has: 1, adopt little rib tire to strengthen friction force between tyre surface and the ice and snow road, but skidproof effect is not remarkable more.2, in some urban districts in the northeast of China, anti-skidding for power actuated vehicle spread ashes, sand on road, not only unhygienic, and labour intensity is very big and certain limitation arranged.3, modal is to realize anti-skidding with rope binding chain on the driving wheel of self-propelled vehicle.Because the spacing of the interchain of anti-slipping chain is bigger, on changeable ice slope road surface, usually occur breakking away.The road surface changes greatly, and owing to the numerous rope with the rope binding, anti-slipping chain can not be dismantled again at any time.The more important thing is that the anti-slipping chain of tens kilogram weights has increased the resistance of wheel rolling, makes huge the increasing of consumption of machine members and fuel.

Fig. 1 of the present utility model is the birds-eye view of anti-skid device, Fig. 2 is the front view of anti-skid device, Fig. 3 is the cutaway view of birds-eye view 1E-E, Fig. 4 is the scheme drawing that anti-skid device hangs on the active bridge of different automobile types, Fig. 5 is the scheme drawing of anti-skid stud riveting dress on offset plate of anti-skid device, its structure is shown in figure (2): be by anti-skid stud offset plate (20), and the bearing gland (1) of Locating extension spring (21) and figure (3), axle (2), sieve cap (3), spacer (4), packing ring (5), hang slide plate (6), supporting plate (7), sprocket wheel (8), cover plate (9), antifriction-bearing box (10), sieve cap (11), spacer (12), packing ring (13), carrier bar pin (14), interlock chain (15), slide rail connecting pin (16), slide rail locating dowel pin (17), slideway (18), slide plate (19), and figure (4) anti-skid device suspension holdfast (22), backguy (23), the moving point of handle (24) and figure (5) pin (25), riveting dress pin (26), anti-skid stud offset plate (band line layer) (27), anti-skid stud critical parts such as (28) is formed.

Two axles (3) of the interlock chain (15) of anti-skid device on supporting plate (7), two bearings (10), under the supporting of two sprocket wheels (8), carry (annotating: 18 of four symmetries simultaneously by the flexible slide rail of carrying, 19 are referred to as the flexible slide rail of carrying) the bonded assembly A of institute, B, C, D anti-skid stud offset plate (20), shown in accompanying drawing (4), select suitable suspension angles to be suspended on the back axle by the chassis actual height of different automobile types, shown in figure (4), with the revolver is example: be pressed in anti-skid stud offset plate A when going up when wheel rolls forward, wheel and anti-skid device constant speed travel forward, at this moment anti-skid stud offset plate A is instantaneous remains static, because anti-skid stud offset plate (20) is by the flexible slide rail (18 of carrying, 19) be connected with interlock chain (15), under enough pulling force of Locating extension spring (21), the instantaneous propulsive effort that produces of anti-skid stud offset plate A is passed to interlock chain (15) and made the interlock chain carry B, C, D anti-skid stud offset plate (20), sprocket wheel (8), antifriction-bearing box (10) rotates to anticlockwise direction synchronously.When the rolling of tire on anti-skid stud offset plate A approaches to stop, before the interlock chain is delivered to anti-skid stud offset plate A with anti-skid stud offset plate B in good time and exactly.For accurately putting in place of anti-skid stud offset plate,, leave suitable gap (about 20-30mm) between two blocks of anti-skid stud offset plates by different diameter of tyres and R sizes.For anti-skid stud offset plate on the go built on stilts promptly, the geometric configuration of anti-skid stud is shown in figure (5), and the assembling of anti-skid stud on offset plate should be that the long back of preceding brachymedial is short.Figure (5) is that the anti-skid stud riveting is contained in the transverse cross-sectional view on the offset plate, so the long back of brachymedial is not short before seeing.When the rolling of tire on anti-skid stud offset plate B approached to stop, anti-skid stud offset plate C can put in place again in good time and accurately.The continuous repetition of This move just can show a safe and reliable anti-ways before the car.

The anti-skid stud of high strength, high hardness (28), riveting are contained on the offset plate (27), and ailhead is petal-shaped (eight lobes), does not promptly damage tire, make under the gravity and obtain higher friction power between tyre surface and offset plate, the ailhead.And the point of the nail below the offset plate embeds ice sheet, even on extremely steep ice slope road surface, wheel can not skid in length and breadth and obtain good skidproof effect.

Change to need remove when anti-skidding when ground-surface, car retardation is gone slowly, and the driver slowly spurs the handle of anti-skid device, and as (24) of figure (4), backguy (23) pulling anti-skid device slides hanging on the slide plate as figure (3), and anti-skid device is along slide plate diagonal upwards forward.Anti-skid device is in slip, because flexible effect of carrying connecting pin (16) on the slide rail, make anti-skid device slightly to intermediate, inclined (transmission shaft direction), like this, flexible carry slide rail with anti-skid stud offset plate and the spacing between the tire become far away, on the go makes the anti-skid stud offset plate press fewer and fewer, removes anti-skidding until all withdrawing from.

When using anti-skid device once again, car retardation is gone slowly, the driver is the handle (24) of pine time anti-skid device slowly, because anti-skid device is along the slideway that hangs slide plate (6) and gravity sag and self-return, because the tire that rolls touches, because the factors such as vibrations in travelling, make anti-skid device very fast get involved again anti-skidding.

Claims

1, a kind of wheel for motor vehicle anti-skid device is characterized in that chain and wheel are synchronized with the movement and carry the wheel for motor vehicle anti-skid device that is constituted of anti-skid stud offset plate with the sprocket wheel of rotation.

2, wheel for motor vehicle anti-skid device according to claim 1 is characterized in that anti-skid stud is housed on the offset plate and wheel for motor vehicle anti-skid device that hook becomes.
