【発明の詳細な説明】
本発明は、耐引張性ワイヤーリングで補強されたビード
が外側のホイールフランジによって限界を定められた載
置面でリムの外側ジャケット上に支承された、空気タイ
ヤを有する車両用リムに関する。DETAILED DESCRIPTION OF THE INVENTION The invention comprises a pneumatic tire in which a bead reinforced with a tension-resistant wire ring is supported on the outer jacket of the rim with a bearing surface delimited by the outer wheel flange. Regarding vehicle rims.
本発明の使用範囲が専ら高速運転自動車、スポーツ・カ
ーおよびレーシング・カーにとって益々使用されている
ような比較的平坦な空気タイヤへの応用に決して限られ
てはいないけれども、一定の有利な用途がある。Although the scope of use of the present invention is in no way limited to applications in relatively flat pneumatic tires, such as those increasingly used for high-speed automobiles, sports cars, and racing cars, certain advantageous applications may be found. be.
これら空気タイヤの秀れた運転特性は、これらタイヤを
して特に高速度に適当なものにさせるが、しかし他方で
は平坦な断面形に基づく貧弱な弾性作用は、欠陥として
、上記長所を相殺する。The excellent driving properties of these pneumatic tires make them particularly suitable for high speeds, but on the other hand the poor elastic behavior due to the flat cross-section offsets the above advantages as a drawback. .
本発明の根本課題は、空気タイヤの弾性作用によって測
定される乗心地を改良すると同時にまっすぐな運行に必
要なリム上のタイヤの正確な着座を保証するにある。The fundamental problem of the invention is to improve the riding comfort as measured by the elastic action of a pneumatic tire while at the same time ensuring the correct seating of the tire on the rim, which is necessary for straight running.
本発明は上記課題を空気タイヤ付の車輛ホイールにとっ
て一般にタイヤの断面に無関係に処理させ従って任意の
断面形状のタイヤへも使用できるものである。The present invention solves the above-mentioned problem for vehicle wheels with pneumatic tires, regardless of the cross section of the tire, and therefore can be used for tires of any cross-sectional shape.
本発明によると上述の種類の自動車ホイールは、ホイー
ルフランジが軸方向断面で見て二つの直線部分に区分さ
れていて、半径方向外側の部分が直径平面に対して半径
方向内側の部分より遥かに大きい角度βを成して傾斜し
ており、二つの部分の間の屈曲点がワイヤーリングの中
心横断面とはゾ同じ直径の延長上にあることを特徴とす
る程度を異にして配向せる画部分の間の移行屈曲部は、
コア・リングの断面中心とほぼ一致する直径上にあるの
が好しく、上記外側部分の該直径平面に対する傾斜角が
40°と70°との間、好しくは45゜の大きさのオー
ダに、これに反して上記内側部分では5°と200との
間、好しくは15°の大きさのオーダにすることができ
る。According to the invention, a motor vehicle wheel of the above-mentioned type is provided, in which the wheel flange is divided into two straight sections in axial section, the radially outer section being much wider than the radially inner section with respect to the diametric plane. The differently oriented drawings are inclined at a large angle β and are characterized in that the bending point between the two parts lies on an extension of the same diameter as the central cross-section of the wire ring. The transition bend between the parts is
Preferably, it lies on a diameter substantially coinciding with the cross-sectional center of the core ring, and the angle of inclination of said outer portion with respect to said diametric plane is between 40° and 70°, preferably of the order of magnitude of 45°. , whereas in the inner part it can be of the order of magnitude between 5° and 200°, preferably 15°.
このように構成せる傾斜断面形状からして、本発明の重
要な部分特徴による上記ホイール・フランジの最大直径
はコア・リングの外径に従った大きさのオーダで調整せ
ねばならない。Due to the inclined cross-sectional shape constructed in this way, the maximum diameter of the wheel flange according to an important feature of the invention must be adjusted on the order of magnitude according to the outer diameter of the core ring.
本発明は、タイヤを直接外側によって支持するホイール
・リムの縁部分に新しい様式の形状を導入し、このため
ホイールが転動する場合空気タイヤとホイール・リムと
の間の動力学的繰返えし運動をする際運転挙動への著し
い反作用が発生する。The invention introduces a new style of geometry in the edge section of the wheel rim that supports the tire directly on the outside, so that when the wheel rolls, the dynamic repetition between the pneumatic tire and the wheel rim is reduced. Significant reactions to the driving behavior occur when driving.
顕著な屈曲部を自体直線状の両部分の方向経路内に有す
るホイール・フランジの断面に角度をつけたかまたは湾
曲させた形状は、作動上の再分割をもたらすことになり
、そのためコア・リングの位置と断面形状へのホイール
・フランジの特定の調和が重要となる。An angled or curved cross-sectional shape of the wheel flange with significant bends in the directional path of both parts, which are themselves straight, will result in an operational subdivision, so that the core ring The specific matching of the wheel flange to its location and cross-sectional shape is important.
上記直径平面に対して比較的小さな傾斜角をなして延長
する急な内側部分は、タイヤ・ビードにとって有効な停
止部を構成する。The steep inner portion extending at a relatively small angle of inclination to the diametrical plane constitutes an effective stop for the tire bead.
このホイール・フランジの方向変換がなおコア・リング
の断面の内側にある高さ、好ましくはこのリング断面の
中間部分でなされるから、この内側部分の少くとも最大
部分は、軸芯方向に投影してコア・リングと一致する。Since this change in direction of the wheel flange is still carried out at a height which is inside the cross-section of the core ring, preferably at the middle part of this ring cross-section, at least the largest part of this inside part is projected in the axial direction. and match the core ring.
この結果ホイール・フランジの上記部分にビードを設け
ることができ従って直つすぐな運行にとって重要なタイ
ヤのリム上での正確な着座を確実にする。As a result, said portion of the wheel flange can be provided with a bead, thus ensuring correct seating of the tire on the rim, which is important for straight running.
他方では、はぼ平坦な方向経過のもとに湾曲せるホイー
ル・フランジの外側部分は、著しい半径方向の弾性運動
に対する載置面と支持面を、ビードに直接続いている空
気タイヤの縁部分に提供する。On the other hand, the outer part of the wheel flange, which curves with a nearly flat directional course, provides a resting surface and a support surface for significant radial elastic movements to the edge part of the pneumatic tire directly following the bead. provide.
例えば高速タイヤの平坦な断面形状に外側のホイール・
フランジの比較的大きい傾斜角が始めから広汎に適して
いる。For example, the flat cross-sectional shape of a high-speed tire
A relatively large angle of inclination of the flange is initially suitable for a wide range of applications.
その上しかもこの傾斜角は、従来の断面形状を有する空
気タイヤにも側壁の顕著な変形を可能にし、リム上のビ
ードの固定し加圧せる着座を欠かさず、これらタイヤの
変形は、ホイール・フランジの湾曲せる外側部分に絶え
ず当接させることによって穏やかに捕捉させる。Moreover, this angle of inclination allows for significant deformation of the sidewall even in pneumatic tires with conventional cross-sectional shapes, requiring a fixed and pressurized seating of the bead on the rim, and these tire deformations are Gentle capture is achieved by constant contact with the curved outer portion of the flange.
上記両部分を傾斜させて延長させた結果としてこのホイ

一定角度で傾斜させる場合、一層簡単にならしめること
になる。The completely low height of this wheel flange, as a result of the sloping extension of both parts, rewards efforts to simplify tire assembly, and furthermore, the mounting and dismounting of pneumatic tires is facilitated by the outwardly conical shape of the wheel flange. The mounting surface of the bead on the outer circumferential surface of the wheel rim that widens toward the front is 10 mm with respect to the wheel axis.
It is even easier if the angle of inclination is of the order of magnitude between and 20[deg.] and preferably approximately 15[deg.].
