Abstract

The present invention relates to tread pattern structure for tyre with high performance used in sport type multifunctional vehicle, more concretely, the object of the invention is to provide a tread structure for tyre with high performance which can improve operation property and braking property. The structure includes plural pattern ditches and two pitch groups with same pitch, and the tread pattern has a block mounted with the plural pitch groups repeatedly. In the tread pattern, choosing the central line (CL) of the width (W) center of the tread as reference, the edge part incline angle (Alpha <1>) of the first block is 10-20 degrees, the edge part incline angle (Alpha <2>) of the second block is 50-60 degrees, thereby a structure having two kinds of incline angles is formed.

Description

The tread pattern structure of high-performance tire
Invention field
The present invention relates to the tread pattern structure of the employed high-performance tire of sport utility vehicle (Sports Utility Vehicle), more particularly, its objective is the structure of the tread contour that the high-performance tire that can improve road-holding property and deceleration and stopping performance is provided.
Background technology
Recently, in the employed tire of vehicle, high-performance tire by in conjunction with and the sizing material that is in harmonious proportion of wide tread groove, and have good adjustment stability, so the customer has the trend of increase to their selection.
Generally speaking, though to the more or less difference that is defined in the tiremaker of the high-performance tire that is different from UHPT (very-high performance tire), normally to can run at high speed, the appellation of tire that flat ratio is low.This tire protector be characterized as V-arrangement, compare with the radial-ply tyre that general passenger vehicle is used, the shaped design of piece is bigger, improves road-holding property and deceleration and stopping performance thus.
But, for general high-performance tire because flat ratio and big block-shaped makes and takes the sensation variation, and the general tire of decorative pattern noise ratio what want big.And the decorative pattern that just is made of the piece that strengthens for there not being otch (kerf) descends road-holding property and the deceleration and stopping performance on the ice and snow road, thereby use has danger in the winter time.
Summary of the invention
The present invention is for the problems referred to above that solve prior art propose, and the piece tire that its objective is the V-type decorative pattern that a kind of and existing uniclinal oblique angle is provided is compared the tread pattern structure of the high-performance tire with two leaning angles of the deceleration and stopping performance that can improve when running at high speed and turning performance.
For achieving the above object, in the tire tread pattern structure by a plurality of grooves and the pitch group who comprises two same pitches (pitch) piece that constitute, that have a plurality of pitch groups of repeated configuration of the present invention, line of centers (CL) with width (W) center of above-mentioned tyre surface is a benchmark, first edge part leaning angle (α 1) be 10 °～20 °, second edge part leaning angle (α 2) be 50 °～60 °, thus structure formed with two kinds of leaning angles.
Description of drawings
Fig. 1 has shown the tread pattern structure according to high-performance tire of the present invention, the figure of the tread contour of the state when being the display of tyre straight-line travelling;
Fig. 2 is the tread contour figure that shows the state of tire surface decorative pattern when turning driving as shown in Figure 1;
Fig. 3 (A), (B) are the figure that the high-performance tire of the V decorative pattern at existing uniclinal oblique angle and the high-performance tire that adopts two (dual) leaning angles of the present invention shape when the actual ground connection is compared;
Fig. 4 is the performance comparison sheet of the present invention and existing high-performance tire.
DETAILED DESCRIPTION OF THE PREFERRED
Below, the present invention is described in detail with reference to the accompanying drawings.
Fig. 1 and Fig. 2 are expressions according to the tread contour figure of the tread pattern structure of the high-performance tire with two kinds of leaning angles of the present invention state when vehicle straight-line travelling and the turning driving.
The present invention as shown in the figure, in tire tread pattern structure by a plurality of grooves and the pitch group's piece that constitute, that have a plurality of pitch groups of repeated configuration that comprises two same pitches, centre line C L with the width W center of above-mentioned tyre surface 1 is a benchmark, first 2 edge part inclined angle alpha 1Be 10 °～20 °, second 3 edge part inclined angle alpha 2Be 50 °～60 °, thereby form structure with two kinds of leaning angles.
On the other hand, as shown in Figure 1, tire is considered horizontal drainage performance and in order to improve deceleration and stopping performance, with second 3 marginal portion inclined angle alpha when straight-line travelling 2Be set at 50 °～60 °, in contrast, as shown in Figure 2, increase for making tire lateral control force (cornering force) with respect to the vertical direction of above-mentioned first 2 edge part when the turning driving, this inclined angle alpha of first 2 1Be set at 10 °～20 °, to scheme to improve operating characteristic and deceleration and stopping performance.
For traveling comfort and reduction noise, in each piece (2,3), form otch (kerf).In above-mentioned otch, the first otch 4a is positioned at the narrowest place of piece width, and 14～21% position is played in the boundary line that the second otch 4b is positioned at the pitch A of piece and pitch B abreast, the position of three cuts 4c to the six otch 4f be arranged on each piece in the middle of the place.
In addition, with respect to vehicle heading, be the circumferencial direction that satisfies tire and horizontal drainage performance, form main horizontal ditch 5, it has with the centre line C L is about 10 °～15 ° inclined angle alpha of benchmark 3And α 4In 5 pieces that are made of whole pitch A and pitch B, each piece is divided into pitch A and pitch B, and the pitch ratio is 1.0～1.6, can realize uniform ground connection distribution and reduce the decorative pattern noise.
Fig. 3 A and B are that the comparison model is the comparison diagram of the ground connection shape of 295/45R20 size for the performance comparison of the high-performance tire of estimating prior art and high-performance tire of the present invention.Fig. 4 measures and tire more in the past and tire of the present invention is braked on drying and wet road surface and the figure of noise.Tire of the present invention and tire in the past relatively all will be dominant on every performance.
Above-mentioned tread pattern structure according to high-performance tire of the present invention has the advantage that improves road-holding property and deceleration and stopping performance by the tread contour with two kinds of leaning angles.
