Embodiment Construction

[0019] Such as figure 1 As shown, the present invention is a novel lightweight bicycle tire, one embodiment of which includes a pair of left and right bead portions, a sidewall portion extending from the bead portion toward the radially outer side of the tire, and bridging the two sidewall portions The tread portion includes the crown in contact with the ground and the shoulders connected to the sidewall, and also includes the ply 1 that is folded back and wrapped around the bead portion to form a circle, and the edge of the ply 1 is folded upward around the bead core 3 While being anchored in the two shoulders, the tread part includes a reinforcing ply 2 and a tread layer 5 arranged on the outer side of the ply in sequence and annularly arranged along the tire circumferential direction. The tire shoulders are overlapped, and the edge of the carcass layer 1 is wrapped around the bead core 3 and is also provided with an anti-friction layer 4 .

Abstract

The invention relate to a novel light bicycle tire which comprises a left tire bead portion, a right tire bead portion, side wall portions and a tire tread portion. The side wall portions extend from the tire bead portions to the radial outer side of the tire, and the tire tread portion is in bridge connection with the two side wall portions. The tire tread portion comprises a crown in contact with the ground and tire shoulders connected with the side wall portions. The novel light bicycle tire further comprises a cord fabric layer folded back to wrap the tire bead portions for a circle, and the edge of the cord fabric layer is folded upwards around a bead core to be anchored in the two tire shoulders in a wrapping mode. The tire tread portion comprises a reinforced cord fabric layer and a tire tread layer which are sequentially on the outer side of the cord fabric layer and annularly arranged in the circumferential direction of the tire, and the reinforced cord fabric layer and the cord fabric layer are arranged on the two tire shoulders in an overlapped mode. The cord fabric layer is folded to wrap the tire bead portions for a circle, and the reinforced cord fabric layer arranged on the outer side of the cord fabric layer is used in combination, so that the tire tread portion is divided into two layers, and the tire side portion is divided into two layers; under the condition of reducing the weight of the tire, the safety and durability of the tire are also guaranteed, weight reduction of the bicycle tire is achieved, and the requirement for riding comfort is met.

Description

technical field [0001] The invention relates to a tire, in particular to a novel lightweight bicycle tire. Background technique [0002] With the increasing number of motor vehicles, urban road congestion is intensifying, and vehicle exhaust emissions have become the main source of urban air pollution. In order to alleviate urban traffic pressure and reduce vehicle exhaust emissions in urban areas, the government is increasingly advocating green travel. [0003] In the prior art, bicycle tires mainly have the following two structures: one is a layer of carcass folded back to wrap the bead part and then overlapped to form three layers of carcass on the tread part and two layers of carcass on the side wall; The ply is folded back and wrapped around the bead without overlapping, and the folded point is fixed to the sidewall to form 2 plies for the tread and 4 plies for the sidewall. The weight of above-mentioned two kinds of bicycle tires is not light enough, can not satisfy p...
