Abstract

FIELD: automotive.

SUBSTANCE: invention is intended for equipping vehicle wheels in order to reduce sliding of pneumatic wheel tires on roads under conditions of ice, snow, dirt. Proposed device comprises metal base, bent in longitudinal direction along tire circle arc. On side ends of the base there are fasteners for fastening it to wheel disk, in which the base has pressed stiffening ribs, and in front and rear part of base plate there are trapezoidal ledges, extension of which coaxially at base angles is made as lugs, through which cable runs with guide tube fixed on one side, through which both ends of cable are passed with loop made in the middle which is put through the hole in fastening bolt head and screwed with butterfly nut, and on the other side with thrust plate having hole for fastening bolt. Additionally in the front part behind the lugs there is front rib with teeth on the outer surface which is rigidly attached along the base length to which two more ribs with teeth on the outer surface are rigidly attached in the middle of the rib forming three triangles on the base.

EFFECT: reduced dimensions and weight of grouser elements, reduced time and costs for their installation and dismantling.

Description

The invention relates to the automotive industry and is intended to equip automobile wheels in order to reduce the sliding of pneumatic tire tires on the roads in icy conditions, snow, dirt.

A device for anti-skid wheels containing a housing with radially oriented beams bearing lugs, connected by a mechanism of their pressing with a washer mounted coaxially to the wheel with the possibility of axial movement, while the lug is made in the form of a segment of the articulated chain, each link of which is equipped with an additional axis located between the main axis the axes of the links, and the clamping mechanism is formed by two ropes, one of which covers the axes in series and its one end is connected to the washer, and the other to the last a single chain link, and with the other rope these axes are covered from above and it is rigidly connected at one end to the last chain link and the other to the end of the elastic element, which is fixed to the device case (ed. St. USSR No. 1643194, class B60C 27/04, publ. 04/23/91).

The known anti-skid wheel has large dimensions and a complex structure.

Of the known closest in technical essence is the anti-skid device, in which the U-shaped lug is made in the form of a link of at least two U-shaped brackets interconnected by longitudinal jumpers fixed outside on the sides of the brackets. The ends of the brackets are bent to the outside with the formation of a U-shaped hook. The U-shaped lug is equipped with an overlay, on the outside of which tread ribs and dirt channels are formed. The lug is connected in series with at least two U-shaped lugs in an anti-skid chain with a connecting element made in the form of a ring with corrugations or loops (Patent RU No. 2363595, CL B60C 27/04, B60B 15, published on 08/10/2009, .).

The known anti-skid device has a complex structure, it is not compact enough when transporting it in the trunk of a vehicle due to the large dimensions of the pressure ring, it takes time to dismantle the levers, which reduces ease of use and, in addition, is not reliable enough due to loss leverage elasticity.

The task to which this invention is directed is to simplify the design of the device, increase its reliability and compactness when transporting it, for example, in the trunk of a vehicle, as well as improve ease of use.

The invention is expressed as follows. The base is made of strip iron, in which trapezoidal protrusions are cut in the front and rear parts, and the eyes are bent at the corners, into which two fastening cables are threaded. To ensure adhesion to the ground, support ribs with teeth are rigidly fixed on the surface of the base, forming a rigid structure of three triangles. The lateral sides of the triangles provide removal of soil from the bearing surface of the wheel.

In FIG. 1 is a front view of the device; FIG. 2 is a side elevational view of the device, in FIG. 3 is a front view of the lug base, FIG. 4 is a side view of the lug base, FIG. 5 is a top view of the lug base.

The device comprises: a metal base of the lug 1 (Fig. 1, Fig. 5), curved in the longitudinal direction along the arc of the tire circumference (Fig. 1, Fig. 3), while fastening elements are made at the lateral ends of the base for attaching it to the wheel disk in addition, stiffening ribs 11 (Fig. 5) are extruded at the base of the lug, and in the front and rear parts the shape has trapezoidal protrusions 12 (Fig. 5), eyelets 2 are located at the corners of the base (Fig. 2, Fig. 4, Fig. 5) through which two cables 3 (Fig. 2) are stretched with fixed on one side an avalanching tube 4 (Fig. 1), through which both ends of the cable are threaded with a loop 5 made in the middle (Fig. 1), threaded through the hole of the fixing bolt 6 (Fig. 1) with a screw-in wing 13 (Fig. 1), and on the other hand, with a thrust plate 7 (Fig. 1), mounted on opposite ends of the cable with an opening for the fixing bolt, in addition to the front of the base behind the eyes, the front rib 8 is rigidly fixed along the entire length of the lug base (Fig. 5) with teeth on the outer surface, to which two more ribs 9, 10 (Fig. 5) with teeth on the outer surface, forming three triangles on the base of the lug, are rigidly fixed in the middle of the ribs at an angle;

The device operates as follows.

In case of heavy snowfall or skidding of the road with snow, when it gets onto a damp dirt road and the adhesion of the wheel contact spot to the supporting surface of the roadway deteriorates, traction control devices are installed on the drive wheels. In this case, the base of the lug 1 (Fig. 1, Fig. 5) is mounted on the surface of the tire of the wheel and secured with a cable due to the mounting bolt and wing with nut 13 (Fig. 1). Traction control devices can improve the engagement of the wheel with the road surface due to the indentation of the ribs with teeth 8 (Fig. 4), 9, 10 (Fig. 4) of the lug base above the surface of the wheel. The location of the ribs of the lug base in the form of three triangles allows to increase the cross-country ability of the car due to the formation of an additional surface of adhesion of the wheel to the ground, because wheel contact with the ground will occur not only along the end surface of the wheel, but also along the side, for example along the inner surface of the track.

When hit on a section of road with a normal surface, traction control devices are removed one by one.

The proposed design of the traction control device will significantly reduce the overall dimensions and weight of the lug elements, significantly reduce the time and cost of their installation and dismantling.
