Title (EN) TIRE TREAD HAVING TREAD BLOCKS WITH INCLINED TRAILING SIDE AND SIPE
(FR) BANDE DE ROULEMENT DE PNEU AYANT DES BLOCS DE BANDE DE ROULEMENT COMPORTANT UN CÔTÉ ARRIÈRE INCLINÉ ET UNE LAMELLE
Abstract:
(EN) Embodiments of the disclosure include a tire tread having tread blocks (24) each defined by a pair of lateral grooves (20) each being asymmetric whereby a first portion (26) of a trailing side (TS24) the tread block is inclined and extends to a peak (28), and whereby a recess (38) projects into tread block below the first portion. Each tread block also includes a sipe (22) extending into the tread thickness from the outer, ground-engaging side of the tread, where the sipe is generally inclined relative to the direction of the tread thickness, such that as the sipe extends into the tread thickness from the outer, ground-engaging side, the sipe extends towards the trailing side (TS24) of the corresponding tread block, the sipe including a groove (40) arranged along the sipe within the tread thickness and spaced below the outer, ground-engaging side of the tread. The groove being asymmetric relative to a centerline (CL22) of the sipe.
(FR) La présente invention concerne, selon des modes de réalisation, une bande de roulement de pneu ayant des blocs de bande de roulement (24) délimités chacun par une paire de rainures latérales (20) dont chacune est asymétrique, moyennant quoi une première partie (26) d'un côté arrière (TS24) du bloc de bande de roulement est incliné et s'étend jusqu'à un pic (28), et moyennant quoi un évidement (38) fait saillie dans le bloc de bande de roulement au-dessous de la première partie. Chaque bloc de bande de roulement comprend également une lamelle (22) s'étendant dans l'épaisseur de bande de roulement à partir du côté externe en prise avec le sol de la bande de roulement, la lamelle étant généralement inclinée par rapport au sens de l'épaisseur de la bande de roulement, de telle sorte que lorsque la lamelle s'étend dans l'épaisseur de la bande de roulement depuis le côté externe en prise avec le sol, la lamelle s'étend vers le côté arrière (TS24) du bloc de bande de roulement correspondant, la lamelle comprenant une rainure (40) agencée le long de la lamelle à l'intérieur de l'épaisseur de bande de roulement et espacée au-dessous du côté externe en prise avec le sol de la bande de roulement. La rainure est asymétrique par rapport à une ligne de centre (CL22) de la lamelle.
