(57) Abstract:Usage: in road transport, in particular in devices temporarily attachable to the wheel. Entity: U-shaped lug 1 is connected to the outer wheel side through the hinge connecting elements 2. Each connecting element consists of two pivotally connected parts. The centers of the connecting elements are connected by springs 3. 1 C.p. f-crystals, 2 Il. The invention relates to road transport, in particular to the design of the device for preventing slippage of the wheels, temporarily attachable to resilient tyres.It is known the use of snow chains, encircling the cross-section of the tire and part of the drive wheels to prevent wheel slippage. Known design braided chain mesh covering of a pneumatic tire and attached to them by the contraction of the extreme branches of chains or steel cables on both sides of the wheel.The disadvantage of these designs is the considerable complexity of attachment of the chains on the wheel and the need to dismantle the wheel. At high speeds of rotation of the wheel in action Central the local anti-skid device for a wheel of the vehicle, containing the lugs, covering part of the outer surface of the wheel associated with the bracket mounted on the wheel hub, and adjustable to and from the transport position into the working position, in which they recorded the springs.A disadvantage of the known design is the high complexity of manufacturing and mounting it on the wheel hub.The aim of the invention is to improve the reliability of mounting anti-skid device on the bus and simplify installation and removal of the device from the wheel.This goal is achieved by the fact that the anti-skid device of the pneumatic tires are covering bus U-shaped lugs, interconnected with one of the outer wheel side through the hinge connecting elements consisting of two pivotally connected parts each, and tightened the tension elements with springs, with one of the connecting elements consists of two detachable parts and lock for installation and removal of the device from the wheel.Comparative analysis with the prototype shows that the proposed anti-skid device differs in that the connecting elements drawn tensioning elements with springs is tstuat the criteria of the invention of "novelty."The comparison of the proposed solutions with other technical solutions in this field of technology is not allowed to reveal in them the characteristics that distinguish it from the prototype, which allows to conclude that the criterion of "substantial differences".In Fig. 1 presents a schematic view of the anti-skid device on the outside of the wheel; Fig. 2 is a side view.Device anti-skid pneumatic tire includes covering the bus U-shaped lug 1, interconnected with one outer side of the wheel articulated connecting elements 2, which tightened the tension elements with springs 3, with one of the connecting elements 2 consists of two detachable parts, joined castle 4 for installation and removal of the device from the wheel.The proposed anti-skid device is manufactured, for example, by bolt Assembly connecting elements 2 made of steel plates and welded (cold-formed/forged from steel rods lug 1. In the open position of the lock 4, the device is hung from the outer side of the wheel so that the lugs 1 tire cover, and the connecting element 2 is stretched to a straight mounting and increased grip lug 1 bus connection elements 2, consisting of two pivotally connected elements, tighten the tensioning elements with springs 3. Possible embodiments of the connecting elements rigid with swivel or flexible (steel cable). Possible embodiments of the lug in the form of a bent rod with a single hinge, or in the form of a bent plate with two hinges.Tightening the tensioning elements with springs 3 connecting elements 2, pre-stretched to a straight position and closed in a single loop lock 4, significantly increases the coupling lug 1 bus wheels. It is known that a slight deformation of the complicated elements cause significant stress in them.In the case of stretching of the spring tension elements or breakage of the lugs are unable to move away from the tire and damage the wing of the car. The fastening device on one outer side of the wheel allows you to install the device without removing the wheel without jacking the car for a short period of time, for example, before jumping the road with icy coating on the rise and removing the device while it is going on the road with a satisfactory coating.
the longitudinal plane of the wheel, at the vertices of which are mounted for rotation perpendicular to the body axis, with the ability to pin mounted on the wheel U-shaped lug, wherein the body is made of three connecting elements, the vertices of which are connected pivotally, each of which in turn consists of two pivotally connected links, the axis of which is drawn between a tensioning elements with springs, with one link of one of the connecting elements consists of two detachable parts, connected by a lock for installation and removal of the device from the wheel.2. The device under item 1, characterized in that the connecting element is flexible.
FIELD: transport engineering.

SUBSTANCE: proposed device contains casing in form of sector enclosing the wheel secured for rotation around wheel axial line. Casing is controlled by handle from driver's cab through system of levers by adjustable gear engagement, with bushing freely fitted on rear axle being rigidly connected with said casing provided with toothed rim. With bushing being shifted along axle it comes into meshing with toothed rim rigidly secured on wheel rim for rotating casing by wheel. With bushing in other position, teeth found on one of its sides engage with teeth of rear axle to fix casing of wheel.
EFFECT: increased cross-country capacity of vehicle, improved control of device.
FIELD: motor-car construction industry.
SUBSTANCE: anti-slipping device for car tires consists of a chained shell with two lines (9) of chain links (11), jointed together at a regular interval by means of an intermediate element (15). Guiding links (23) are engaged with the intermediate elements (15). The guiding links (23) connect chained shell with retaining brackets (29) placed on car wheel in a star-like manner. The retaining brackets (20) and chained shell are connected by means of corresponding guiding link (23) of the chain. Besides chained shell can be turned over by means of guiding links (23) releasing.
EFFECT: even wear of all elements around circle.
