Vehicle tire with antislip device

FIELD: transport engineering; tires.

SUBSTANCE: proposed tire is provided with antislip members in form of stud made of wear resistant material and arranged over tire circumference. Studs are hinge-interconnected by means of fasteners to form flexible chain embedded in tire body with projection of stud over outer surface by 0.5-2 cm.

The invention relates to improving the handling characteristics of motor vehicles when driving on icy roads and allows you to improve traffic safety in difficult road conditions ice.

Known adjustable anti-skid device for elastic tires containing the anti-skid elements in the form of studs rigidly mounted on a supporting part in the form of a one-piece ring located in the annular recess of the tread on the tire circumference (RF patent No. 2055750, the IPC 06, 27/18, publ. 10.03.96 year).

The disadvantage is a small lifetime.

You know the anti-skid device wheeled vehicles (certificate of the Russian Federation for useful model № 1982, the IPC 60 27/16, publ. 16.04.96 g)containing jumpers with means for attaching them transversely, having a side that interacts with the road surface, the spikes in the form of triangular teeth, and jumpers in the form of flat metal plates mounted stationary with two sides on the elastic tape with the possibility of setting the circumference of the tire tread.

The disadvantage is the complexity of the design and inconvenience in operation.

Known tyre for vehicle wheels with removable anti-skid device, in which a special ring groove protector is located with the geared end the mi in the form of hooks curved Hoop with put on him by the anti-skid elements in the form of washers, which can be either round or square (RF patent No. 2073615 IPC 60 With 27/06, publ. 20.02.97 year).

This design is not robust enough and has a small life.

Known special antiskid protector pneumasin representing a flexible circuit, composed of a separate hinge interconnected segments on the working surface and the alignment tabs on the sides on the inner surface, with a lock-snap closure on one end segment of the circuit for connection with another ring and a fixture for mounting to the drive wheels at the other end segment (RF patent No. 2091245, the IPC 60 27/14, publ. 29.09.97 year).

This device is complicated in construction and is not reliable enough, because in the process of operation can fly and cause damage to the chassis of the vehicle or an accident.

The closest to the invention is adjustable anti-skid device for elastic tires containing the anti-skid elements in the form of studs rigidly fixed on the supporting part, made in the form of a ring of flexible durable material located in the annular recess of the tread on the tire circumference (RF patent No. 20055750, the IPC 60 27/18, publ. 10.03.96 year).

The disadvantage of this device is a small lifetime.

The objective of the invention is to improve the reliability and the dolgovechnosti anti-skid device on the bus the wheels of the vehicle.

The problem is solved tire for vehicle wheels with anti-skid device containing the anti-skid elements in the form of studs, made of wear-resistant material connected to the flexible circuit located around the circumference of the tire, in which unlike the prototype spikes pivotally interconnected by means of fasteners in the flexible circuit, which flooded the interior of the tire so that the spikes protrude above its outer surface by 0.5-2 see Spikes can have the configuration of the outer surface, the gear with the ground, in the form of a triangular or rectangular, or trapezoidal, or wavy teeth. Each spike is made in the form of one-piece construction or assembled from flat elements. Fasteners for connecting studs in the flexible circuit can be made in the form of plates located on the sides of studs or near their base.

The proposed constructive performance tires greatly improve braking on a slippery surface due to the firm grip with it's built into the tire anti-skid device. Formed by the spiked chain is durable, reliable and not prone to fall off the bus. This reduces the chance of accidents on the roads in winter conditions, ice.

Figure 1 shows a bus filled her flexible circuit is of thorns; figure 2 shows fragments of the flexible circuit, with different connection fasteners; figure 3 shows the elements of the flexible circuit in the form of spikes with different configuration.

In the tire 1 to the wheels of the vehicle (figure 1) filled anti-skid device 1, which is a flexible circuit (figure 2), consisting of individual elements in the form of studs 3, connected by a hinge by means of plates 4, which can be installed on the sides of the studs on the outside of the chain (Posa), and inside the chain (posb), or at the base of thorns (potw).

Configuration spikes (figure 3) may vary as the shape of the base and form the outer surface.

The device operates as follows.

Pre-assembled flexible circuit 2 of the individual spikes 3, pivotally interconnected by means of plates 4. Chain length is determined by the circumference of the tire, i.e. the circumference of the form in which the casting of the bus.

Made of flexible circuit is installed around the circumference of the inside of a form for casting the bus so that she was standing in the middle of the future tire. The form is filled rubber. Ready bus is obtained with the anti-skid device, securely fastened in its column.

Thus, the proposed solution allows to increase the reliability and durability of the device is of the snow on the bus the wheels of the vehicle.
