Embodiment Construction

[0011] The present invention relates to bias ply tires which are used in particular as truck tires, transporter tires and OTR tires or crawlers on stony ground and bad roads, and which bias ply tires The ratio of section width to section height (determined according to E.T.R.T.O. standards) is 1 or 0.85.

[0012] figure 1 A beltless pneumatic vehicle tire of bias design is shown having a tread 1, sidewalls 2, bead regions 3 with bead cores 4 and a plurality of layer carcass 5. The carcass 5 is made up of carcass inserts 6, 6' outside of an inner layer (not shown) of known design on the circumference of the tyre, and in the axial direction at It extends radially between the bead cores 4 of the two bead regions 3 and also along and within the sidewalls 2 and the tread 1 . In the case of the represented embodiment, each bead area 3 has three bead cores 4 made of steel cords in a known manner. In the case of the illustrated embodiment, four carcass inserts 6 are also provided ...

Abstract

The invention relates to a beltless pneumatic tire for a vehicle, having a ratio of cross-sectional width to cross-sectional height (determined as per E.T.R.T.O. standards) of 1 or 0.85 and comprising a carcass having a diagonal design, which carcass has a plurality of carcass inserts (6, 6'), which are arranged one over the other and which have reinforcements (7), which are embedded in a rubber matrix, extend parallel to each other, and are made of a textile material, wherein the reinforcements (7) in carcass inserts (6, 6') extending adjacent to each other are arranged in a cross arrangement and extend at an acute angle to the circumferential direction at the tire zenith, which acute angle is identical in all carcass inserts (6, 6'). The angle (alpha, beta) included by the reinforcements (7) with the circumferential direction at the zenith of the tire is between 28 DEG and 34 DEG for a tire having a ratio of cross-sectional width to cross-sectional height of 1 and between 26 DEG and 32 DEG for a tire having a ratio of cross-sectional width to cross-sectional height of 0.85.

Description

technical field [0001] The present invention relates to a beltless pneumatic vehicle tire having a section width to section height ratio (determined according to E.T.R.T.O. standards) of 1 or 0.85, with a carcass of bias design, The carcass comprises a plurality of carcass inserts arranged one above the other and having reinforcing elements of textile material embedded in a rubber matrix and extending parallel to one another, in a plurality of adjacently extending carcass The reinforcing elements in the inserts are arranged in cross-bracing assemblies with respect to each other and extend at the apex of the tire at an acute angle with respect to the circumferential direction, which is equal in all carcass inserts. Background technique [0002] Although radial tires have been established in favor of bias ply tires in many fields, especially in the field of pneumatic tires for automobiles, bias ply tires are still more suitable for tires subjected to high stress ( including o...
