Abstract

The utility model relates to a new-type tire with middle grooves, which is provided with middle grooves and intermediate ribs in the middle of crown patterns. The utility model is suitable for any vehicle with pneumatic tires and has the advantages of simple structure, easy fabrication, and strong practicability. The utility model can effectively prevent the longitudinal and transverse slides of vehicles and strengthen adhesion property between tires and ground.

Description

New-type tyre with middle grooves

The utility model relates to a kind of tire for vehicles, has the tire of medial launder flower and intermediate rib line on particularly a kind of crown.

At present, the tire that people use, its crown is made with abrasion resistant rubber, directly bears friction and whole load, can alleviate the suffered impact of carcass plies, and protect the carcass plies and the inner tube of a tyre to avoid mechanical damage.For making tire and ground that good adhesion value be arranged, prevent that in length and breadth to slippage etc., crown is provided with various decorative patterns.Highway tread pattern is applicable to road surface preferably; The decorative pattern of cross-country tread pattern is dark, and cross country power is stronger, is applicable to soft surface and thick, and when chevron patten was installed, the tip of the wheel crown decorative pattern of tending to act was consistent with hand of rotation, in order to avoid decorative pattern is clogged by earth; Dual purpose tread pattern is between highway tread pattern and cross-country tread pattern.

The purpose of this utility model is being provided with of crown decorative pattern, and increases medial launder, improves tire with ground-surface adhesion value, prevent effectively vehicle in length and breadth to slippage.

The purpose of this utility model is achieved in that shown in Fig. 1 crown cross sectional drawing, the medial launder (1) of certain width is set in the middle part of crown (5), medial launder (1) is provided with intermediate rib (2), distance is the 1/4--1/3 of crown width between the both sides of the chest, the degree of depth of medial launder (1) is the 1/8--1/7 of crown (5) width, and intermediate rib (2) can be arranged to the width of different size according to different purposes.The crown decorative pattern (3) of other form can be arranged in the both sides of medial launder (1).Keep existing situation for carcass plies (8), cushion layer (7), sidewall (6) and tire shoulder (4).

Do the cross-country time spent when the utility model, can widen the width of intermediate rib (2),, can suitably reduce the width of intermediate rib (2), can make medial launder (1) part even whole kiss the earth when the utility model is done the heavy lift time spent.When brake, intermediate rib (2) can reduce braking distance, promptly prevents the lateral direction of car slippage, as " whipping crust " phenomenon of braking and occurring often.

The utility model is simple in structure, practical, be provided with rationally, can travel at soft surface again at better road traveling, in length and breadth to the excessive phenomenon of slippage, increases tire and ground-surface adhesion value in the time of can preventing to brake effectively.

Claims

1, a kind of novel tire that has medial launder comprises crown decorative pattern (3), tire shoulder (4), crown (5), sidewall (6), cushion layer (7), carcass plies (8), it is characterized in that crown (5) is provided with medial launder (1) and intermediate rib (2).
