Problems solved by technology

[0004] But even adopt this high-drainage and low-noise semi-steel car tire, this invention does not mention that there is tread block chamfering or chamfering, and the pattern separation groove between the circumferential main grooves does not have a special curve or broken line shape, nor It is not mentioned whether the tire shoulder has a structure to shield the noise between the circumferential main grooves when the tire is running

Embodiment Construction

[0028] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0029] In order to achieve the purpose of the present invention, figure 1 A partially developed plan view of a tread portion according to an embodiment of the present invention is shown. The tread pattern of this invention is circumferentially continuous in the vertical direction in the drawing. The first circumferential main groove 1a, the first circumferential pattern block 9a, the second circumferential main groove 1b, the second circumferential pattern block 9b, and the third circumferential main groove are respectively arranged on the tread from the outer shoulder of the tire to the outer inner shoulder of the tire. 1c, the third circumferential pattern block 9c, and the fourth circumferential main groove 1d. The third circumferential pattern block 9c is provided with a Z-shaped separation groove 4, and the first circumferential pattern block 9a and t...

Abstract

The invention discloses an asymmetric tread pattern tire of a recreational vehicle. Four circumferential main grooves are formed in the tire tread, the four circumferential main grooves are circumferential straight grooves, and three circumferential tread pattern blocks are formed between the four circumferential main grooves. Curve grooves are formed in the outer shoulder of the tire, and the curve grooves do not communicate with the adjacent circumferential main grooves. Transverse grooves are formed in the inner shoulder of the tire, and the transverse grooves communicate with the adjacent circumferential main grooves. Z-shaped separation troughs are formed in the circle of circumferential tread pattern block adjacent to the inner shoulder of the tire, and non-through oblique grooves are formed in the other two circles of circumferential tread pattern blocks. Steel sheets are arranged on the outer shoulder and the inner shoulder of the tire. Chamfered edges are formed on the cross poly-lines of the Z-shaped separation troughs and the circumferential tread pattern blocks. Cut corners are formed on the sharp parts of each tire block. According to the asymmetric tread pattern tire of the recreational vehicle, noise can be further lowered and blocked, and the road holding capacity of the tire can be improved.

Description

technical field [0001] The invention relates to an automobile tire, in particular to an asymmetric pattern tire for a recreational vehicle. Background technique [0002] Tires are a common and important part of a car. The pattern design of tires is related to the three important parameters of tire grip, water drainage, and quietness. These three are mutually restraining or even conflicting. [0003] Chinese Utility Model Patent Specification CN203567481U discloses a semi-steel car tire with high drainage and low noise. The tire crown is provided with pattern blocks and pattern grooves arranged at intervals, the groove bottom of the pattern groove is provided with groove bottom knurling, and the side wall of the pattern groove is provided with pattern groove side wall knurling, which is beneficial to break the gap between the pattern groove and the ground. Pump air to reduce driving noise; pattern blocks include central pattern blocks, inner pattern blocks and outer pattern ...
