Pneumatic vehicle tyre having a profiled tread strip which is provided laterally externally with circumferential bands (3), the outer edge of which comprises projections (5, 6) which are separated from one another by grooves (4) extending transversely to the circumferential direction of the tyre, and said projections extend at different lengths laterally towards the outside in the circumferential direction of the tyre, whereby, when viewed in the circumferential direction of the tyre, every second projection has the same transverse extension, characterised in that the lateral faces (7) of the shorter projections (6) extend into a flat recess (9) which terminates at the upper edge of the lateral wall (10) of the tyre and is defined by sharp edges both laterally and at the lower edge, the edges of said recess extending substantially radially and being identical to the lateral edges of the projections which have the greatest extension laterally towards the outside, and in that the lateral faces (7) of the shorter projections (6) extend substantially parallel to the lateral faces (8) of the longer projections (5).

Description

i 151539in 151539

Opfindelsen angår et køretøjsdæk med profileret slidbane, der ved hver side har en i dækkets omkredsretning forløbende slidbanekantrib-be, hvis udadvendende kantdel består af fremspring, der er adskilt fra hinanden ved hjælp af tværgående noter og strækker sig forskelligt 5 langt ud mod siden, hvorhos hvert andet af de i dækkets omkredsretning efter hinanden følgende fremspring har samme længde set i dækkets tværretning.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a vehicle tire with a profiled tread having at each side a tread extending in the circumferential direction of the tire, the outward edge of which consists of projections which are spaced apart by transverse grooves and extend variously far out to the side. each other of the successive projections in the circumferential direction of the tire has the same length seen in the transverse direction of the tire.

Fra trykskriftet LU-A-66464 kendes et radialdæk til lastautomobiler, hvor slidbanen i sine sideområder har tværriller, mellem hvilke der 10 findes grove skridknaster. Disse skridknaster er anbragte på en sådan måde, at der skiftevis findes længere udragende og mindre langt udragende skridknaster, således at de længere udragende skridknaster i omkredsretningen danner visse gribeflader, der i begrænset omfang kan forbedre dækkets gribeevne.From the publication LU-A-66464, a radial tire is known for trucking vehicles, in which the tread in its side areas has transverse grooves, between which there are 10 coarse skids. These skids are arranged in such a way that longer protruding and less far protruding skids are alternately arranged, so that the longer protruding circumferential lugs form certain gripping surfaces which can to a limited extent improve the grip ability of the tire.

15. Disse flader er imidlertid så små, at der ikke kan opnås nogen væsentlig virkning.15. However, these surfaces are so small that no significant effect can be obtained.

Formålet med opfindelsen er derfor at udforme slidbanens sidekant-områder og samtidig dækkets skulderområde på en sådan måde, at disse dækafsnit i større grad kan bidrage til en forbedret gribeevne og 20 dermed kraftoverførsel.The object of the invention is therefore to design the side edge areas of the tread and at the same time the shoulder area of the tire in such a way that these tire sections can to a greater extent contribute to an improved gripping ability and thus power transmission.

Denne opgave løses ifølge opfindelsen ved, at sidefladerne af de korteste fremspring går over i en flad ved den øverste kant af dækkets sidevæg afsluttet udsparing, der både ved sine sider og sin nederste kant begrænses af skarpe kanter, og hvis i det væsentlige radialt 25 forløbende kanter stemmer overens med sidekanterne af de fremspring, der strækker sig længst ud mod siden, og at sidefladerne af de korteste fremspring forløber i det væsentlige parallelt med de længste fremsprings sideflader. Derved får dækket ifølge opfindelsen en større gribeevne ved slidbanekanten, idet hver udsparing, der set i dækkets 30 omkredsretning ved hver side begrænses af de mellemliggende fremspring, foruden af de derved dannede skarpe sidekanter også begrænses af en skarp kant ved sin radialt nederste side. Udsparingernes radiale kanter, der samtidig udgør de mellemliggende fremsprings sidekanter, får således en tilnærmelsesvis ens bredde over hele deres 35 længde, så de mellem udsparingerne beliggende fremsprings sidekanter danner en optimal gribeflade, f.eks. ved kørsel i løst sand.This object is solved according to the invention in that the side surfaces of the shortest projections change into a surface at the upper edge of the sidewall of the tire completed recess, which is limited at both its sides and its lower edge by sharp edges, and if substantially radially extending. edges align with the side edges of the projections extending farthest to the side, and the side faces of the shortest projections extend substantially parallel to the side faces of the longest projections. Thereby, the tire according to the invention has a greater grip ability at the tread edge, with each recess seen in the circumferential direction of the tire 30 at each side being limited by the intermediate projections, in addition to the sharp side edges formed thereby also being limited by a sharp edge at its radially lower side. Thus, the radial edges of the recesses, which at the same time constitute the lateral edges of the intermediate projections, have an approximately equal width over their entire length, so that the lateral edges of the recesses form an optimal gripping surface, e.g. when driving in loose sand.

På tegningen er en foretrukken udførelsesform for køretøjsdækket ifølge opfindelsen anskueliggjort, og hver viser fig. 1 et radialt delsnit gennem slidbanepartiet af et dæk ifølge 151539 z opfindelsen, og fig. 2 en plantegning i delbillede af dækkets slidbane.In the drawing, a preferred embodiment of the vehicle tire according to the invention is illustrated, and each shows fig. 1 is a radial partial section through the tread portion of a tire according to the invention; and FIG. 2 is a plan view in section of the tire tread.

Den midterste del af slidbanen udgøres af to i dækkets omkredsretning forløbende indre slidbaneprofil ribber 1, der begrænses af zig-5 zagformede omkredsnoter 2. Slidbanen har ved hver yderkant en ydre slidbanekantribbe 3, der ved den udadvendende side er forsynede med tværnoter 4, der strækker sig over tilnærmelsesvis den halve bredde af slidbanekantprofilringen, og mellem hvilke der således er dannet i dækkets omkredsretning efter hinanden følgende fremspring 5,6, af 10 hvilke hvert andet fremspring er trukket tilbage i retning mod dækmidten i forhold til de derimellem liggende fremspring. Sidefladerne 7 af fremspringene 6 er trukket tilbage i forhold til sidefladerne 8 af fremspringene 5.The middle portion of the tread is comprised of two inner tread profile ribs 1 extending in the circumferential direction of the tire, which are constrained by zig-zag-shaped circumferential grooves 2. The tread has at each outer edge an outer tread rib 3 provided at the outward side with cross grooves 4 extending about half the width of the tread edge profile ring, and between which are thus formed in the circumferential direction of the tire 5,6, of which 10 every other protrusion is retracted in the direction of the tire center relative to the protrusions therebetween. The side surfaces 7 of the projections 6 are retracted relative to the side surfaces 8 of the projections 5.

Sidefladerne 7 går endvidere i retningen nedad over i en flad for-15 dybning 9, der ender tilnærmelsesvis ved den øverste kant af dækkets sidevæg 10. Set fra siden er fordybningen 9 tilnærmelsesvis trapezfor-met. Dens sidekanter forløber skråt, og disse danner sidebegrænsningerne af fremspringene 5. Der ligger således to efter hinanden følgende noter 4 inden for breddeudstrækningen af hver fordybning 9, således 20 som det ses i fig. 2.The side faces 7 further extend in the downward direction into a flat recess 9, which ends approximately at the upper edge of the sidewall 10. The recess 9 is approximately trapezoidal. Its lateral edges extend obliquely and these form the lateral boundaries of the projections 5. Thus, two consecutive grooves 4 lie within the width extension of each recess 9, as seen 20 in FIG. 2nd
