〈産業上の利用分野）
冬の圧雪路、氷盤面において発進、制動、登板、下り坂
の安全性を向上させた冬用タイヤのためのトレッドパタ
ーンに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tread pattern for winter tires that improves the safety of starting, braking, climbing, and descending slopes on snow-packed roads and icy surfaces in winter.
（従来の技術）
従来の冬用タイヤのトレッドはトレッド接地面から直角
ないし直角以上の角度で作られていて前方へやや倒れる
形に変形し摩擦抵抗の減少を招いていた。(Prior Art) The treads of conventional winter tires are made at a right angle or at an angle greater than a right angle from the tread contact surface, and are deformed into a shape that tilts slightly forward, resulting in a decrease in frictional resistance.
（発明が解決しようとする問題点）
従来の冬用タイヤのトレッドパターンが接地面で変形し
摩擦抵抗が減少するため圧雪路、氷盤面で充分トレッド
パターンの性能が出しきれていなかった。(Problems to be Solved by the Invention) The tread pattern of conventional winter tires deforms on the contact surface and reduces frictional resistance, so the tread pattern has not been able to achieve its full performance on packed snow and ice surfaces.

により調整するものである。(Means for Solving the Problems) In order to solve the above-mentioned problems of conventional tread patterns, in this invention, when a forward or backward driving force is applied, the tread changes the relationship between the driving force and the vehicle weight. In order to maximize the friction surface of the tread contact surface at

程度の効果である。(Function) In the part where the normal line 131 from the tread base (1) to the trend contact surface (2) is tilted backwards, when forward driving force is applied, the rubber hardness, inclination angle, and tread thickness are related. This causes the tread angle to shrink, expand, and stand up, thereby increasing the frictional effect, and since the patterns are arranged one behind the other, the backward driving force and braking have the same effect. The effect is stronger on uphill roads and downhill slopes, and when driving on flat roads, the effect is small except for sudden starts and accelerations, and the effect is about the same as that of ordinary tire treads.

できる。The tread pattern has a pattern in which the normal line (3) of the tread side wall (4) is tilted backward from the tread base 6) to the tread contact surface (2) with respect to the tire forward direction. ) is a pattern in which the normal line (3) is inclined forward from the tread base (1) to the tread contact surface (2), and the effect can be achieved by any combination of these two patterns. able to demonstrate.

For example, in the case of substances such as air and water, the rate of action differs depending on the construction of curves and angles. In contrast to conventional tire treads, the normal line extends somewhat perpendicularly from the axis of rotation.

、法線が後傾している方が効果は大きくなる。又、制動
、下り坂の安全性という点では。The tread of the present invention may be tilted backward in the forward direction of the vehicle with respect to the vertical line from the axis of rotation, or tilted forward.
Because both tread patterns are arranged, the normal line of the tread side wall to the forward direction is upright when starting or climbing on a road with a low resistance ratio such as a snowy road or ice floe surface that is not an interlocking body. The effect is greater when the normal line is tilted backwards with respect to the rotating body rotating in the forward direction. Also, in terms of braking and downhill safety.
前進方向に対するトレッド側壁の法線が前傾している方
が、効果とあげることができる。It is more effective if the normal line of the tread side wall to the forward direction is inclined forward.
従って、トレッドパターンの接地タイム、ロウルアノブ
効果が増大し相乗効果をあげることになる。Therefore, the ground contact time of the tread pattern and the rolling knob effect increase, resulting in a synergistic effect.
