Stone-clamping preventing tyre

Abstract

The invention provides a stone-clamping preventing tyre, and relates to a tyre. The tyre comprises a tyre body and tyre surface patterns; first main channels in the shape of ring and second main annular channels in the shape of wave type ring are respectively arranged on two sides of the tyre surface patterns along a centre line; a central pattern block is formed between two first main channels; a plurality of side pattern blocks which are uniformly distributed along the tyre surface are formed between the two main channels at the same side; a plurality of tyre shoulder pattern blocks which are uniformly distributed along the tyre surface are respectively arranged outside the two main channels; two adjacent side pattern blocks are separated through an obliquely arranged side pattern channel; two ends of each side pattern channel are communicated with the two main channels, and reversely expanded to form triangular stone removing areas; and the two triangular stone removing areas are respectively matched with the two main channels to form large triangular areas for removing the stones in the two main channels. According to the stone-clamping preventing tyre provided by the invention, the basic performances such as pulling, draining and wear resisting are ensured under the condition that the designs of the bottoms of the channels are unchanged; and moreover, the stone-clamping preventing performance of the tyre can be improved.

Description

technical field [0001] The invention relates to a tire. Background technique [0002] A tire for a vehicle has a carcass and a tread pattern. Nowadays, the road surface is complicated. In addition to paved roads such as cement and asphalt roads, there are also some non-paved roads or damaged cement roads. Stones of various sizes are often scattered on these roads. When tires drive on such roads, The bottom of the groove of the tread pattern is often easy to embed stones of similar size and clamped in the groove, so that the clamped stones are not easy to be discharged even when the tire is running at high speed, and the stones stay at the bottom of the groove for a long time It is easy to puncture the rubber material at the bottom of the groove when it is squeezed, which seriously affects the service life of the tire. [0003] Vehicles running on various road sections have different requirements for tire performance. Generally speaking, on paved roads, the requirements for...

Problems solved by technology

[0004] In the prior art, in order to avoid the phenomenon of stones at the bottom of tread pattern grooves, technical improvements are often made at the bottom of tread grooves, such as changing the structure of the groove bottom, setting small bosses, setting fur rubber, or using diamond groove bottoms, etc. However, these methods often affect the drainage performance of the tire due to the volume occupied by such groove bottom settings, and individual groove bottom designs will also increase the processing difficulty of tire molds
