Embodiment Construction

[0036] figure 1 A partial view of a tread 1 according to a first embodiment of the invention is schematically depicted.

[0037] The tread 1 comprises a plurality of rubber blocks 3, one of which has here been painted gray to make the invention easier to understand. Said blocks are formed on each side of a median plane 5 which divides the tread 1 into two parts. Here, each block 3 extends continuously towards the outside of the tread at the median plane 5 , ie said block is not divided in the direction of the outside of the tread by circumferential grooves and / or offset grooves. More particularly, each block is delimited by a first groove 7 , a second groove 9 and a third groove 11 . A first groove 7 extends at the median plane 5 towards the first edge 8 of the tread and a second groove 9 also extends at the median plane 5 towards this same first edge 8 but with an offset in the circumferential direction . The first groove 7 and the second groove 9 have the same curvature ...

Abstract

The invention relates to a tire tread comprising a plurality of blocks (3) made of rubber material formed on both sides of a median plane (5), the Said median plane (5) divides said tread (1) into two parts. Each block (3) extends continuously from said median plane towards the outside of said tread. Each block consists of two grooves (7, 9) of curvature C leading to the first edge (8) of the tread and extending from the first The groove (7) is defined by a third groove (11) extending towards a second edge (10) of said tread, said second edge (10) being opposite to said first edge (8), said first The second groove (9) leads to said third groove (11).

Description

technical field [0001] The present invention relates to a motor vehicle tire tread comprising a directional tread pattern, and more particularly to a tread having a plurality of curved grooves extending on each side of a median plane. Background technique [0002] Document US 4057089 discloses a motor vehicle tire tread comprising a directional tread pattern. More specifically, the tread comprises a plurality of curved grooves extending on each side of a median plane. The curved grooves respectively start at one of the edges of the tread and extend towards the median plane, but do not reach it. Thus, said tread pattern comprises a central main block extending in the circumferential direction, to which a plurality of sub-blocks defined by said curved grooves are attached. [0003] The tread disclosed in document US 4057089 has a certain number of disadvantages. Firstly, the presence of the central main block hinders the flow of water and makes its removal through the curve...
