Embodiment Construction

[0036] Figure 1 to Figure 3 A first embodiment of an advanced ice grip device or cleat 10 is shown, the first embodiment advanced ice grip device or cleat 10 comprising a body 12 and a pin 14 connected to the body 12, the The body 12 is configured to be received in a corresponding recess provided in a tread portion of the tyre. The anti-skid pin 10 extends along the longitudinal axis Z. The expressions "radial", "radially", "perpendicularly" or "perpendicularly" are all defined relative to the longitudinal axis Z.

[0037] Particularly, image 3 The body 12 is shown to include a top flange 16 and a bottom flange 20 connected by a neck or shaft 18 having a cross-sectional area that is larger than either the top flange 16 or the bottom flange 20. Small. The pin 14 is connected to the top flange 16 and is arranged at the end of the cleat 10 opposite the bottom flange 20 . The various parts of the cleat 10 may be formed as separate components, eg of different materials, which ...

Abstract

An ice grip device comprises a body configured to be received in a recess provided in the tread portion of a tire and a pin connected to the body, wherein the body comprises a top flange connected tothe pin, a shaft and a bottom flange arranged adjacent to one another along a longitudinal axis, each having a cross-sectional area perpendicular to the longitudinal axis, wherein the cross-sectionalarea of the shaft is smaller than the cross-sectional area of the top flange and the bottom flange, respectively, wherein the bottom flange includes a main portion centered on the longitudinal axis and a single tail portion that extends radially outwardly from the main portion with respect to the longitudinal axis.

Description

technical field [0001] The present invention relates to an advanced ice gripping device for a pneumatic tire and a pneumatic tire provided with one or more such devices. Background technique [0002] Ice gripping devices, also known as stud pins, are used to improve the traction of winter tires on icy roads and generally consist of a body embedded in and protruding from the tread portion of the tire Use the pin to scrape the ice. Interaction between the pins and the road surface may cause premature wear of both the road surface and the device, and may also cause displacement of the device within the tread portion. Displacement of the device within the tread portion can impair traction properties or even cause the device to fall off. One way of preventing displacement of the device is to reduce the size of the recess in the tread portion for receiving the device, which provides a tight fit between the device and the tread portion. However, too tight a fit can make it diffi...
