【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は、自動車の車輪を車軸に対して支持するための支持装置に関するも のである。 The present invention relates to a supporting device for supporting a vehicle wheel on an axle.

【0002】[0002]

【従来の技術】[Prior art]

従来、自動車の車軸の両端部に車輪を支持する装置として、図2に示すような 構造のものがある。 2. Description of the Related Art Conventionally, there is a device having a structure as shown in FIG. 2 as a device for supporting wheels on both ends of an axle of an automobile.

【0003】 この装置は、車軸管32から露出した車軸31の端部に、その車軸と一体でハ ブ33を形成し、このハブ33にボルトを介して車輪34を装着している。また 、車軸34の外周と、車輪管32の端部に固着したハブケーシング35の間に深 みぞ玉軸受36又は円すいころ軸受やころ軸受を設け、この軸受36により車軸 31を回転自在に支持している。In this device, a hub 33 is formed integrally with the axle 31 at the end of the axle 31 exposed from the axle tube 32, and wheels 34 are attached to the hub 33 via bolts. Further, a deep groove ball bearing 36 or a tapered roller bearing or a roller bearing is provided between the outer circumference of the axle 34 and the hub casing 35 fixed to the end of the wheel tube 32. The bearing 36 rotatably supports the axle 31. ing.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記図2に示す装置においては、車軸31とハブ33が一体に形成されている ため、車軸31には、車輪と路面からのモーメント荷重と、エンジンから車輪へ 伝達するトルク(捩り力)の両応力が作用することになり、車軸31の軸径は、 その応力に耐え得るだけの十分な強度を確保できる大きさで設定する必要がある 。 In the device shown in FIG. 2, since the axle 31 and the hub 33 are integrally formed, the axle 31 has both the moment load from the wheel and the road surface and the torque (torsion force) transmitted from the engine to the wheel. Since stress acts, the shaft diameter of the axle 31 needs to be set to a size that can ensure sufficient strength to withstand the stress.

【0005】 しかし、車軸31の径を大きくすると、車軸管32や軸受36が大型化し、取 付けスペースの増大と重量増を生じさせる不具合がある。However, when the diameter of the axle 31 is increased, the axle tube 32 and the bearing 36 are increased in size, which causes a problem that the mounting space is increased and the weight is increased.

【0006】 また、従来の装置に使用される深みぞ玉軸受36は、内輪と外輪がそれぞれ車 軸31とハブケーシング35に直接圧入嵌合して組込まれるが、このような圧入 により深みぞ玉軸受36には大きな軸受すきまが残留し、ガタが生じやすい不具 合がある。このため、車輪の支持剛性が低くなり、ブレーキの作動フィーリング が悪くなる問題がある。In the deep groove ball bearing 36 used in the conventional apparatus, the inner ring and the outer ring are assembled by directly press-fitting them into the axle 31 and the hub casing 35, respectively. A large bearing clearance remains in the bearing 36, which may cause play. For this reason, there is a problem that the supporting rigidity of the wheels is lowered and the operation feeling of the brake is deteriorated.

【0007】 さらに、車軸31とハブ33が一体に形成されているため、それらの加工性が 悪く、又車軸31が長尺になるため、車軸31の加工精度や、ハブ33の車輪装 着面の振れ精度を高精度に出すことが難しい問題もある。Further, since the axle 31 and the hub 33 are integrally formed, their workability is poor, and since the axle 31 becomes long, the machining accuracy of the axle 31 and the wheel mounting surface of the hub 33 are reduced. There is also a problem that it is difficult to obtain a high degree of runout accuracy.

【0008】 この考案は、上述した従来の支持装置の問題点を解決するためになされたもの で、車軸に対する必要強度を低くでき、しかも組込後の軸受すきまが小さくて高 精度に車輪を支持できる車輪支持装置を提供することを目的としている。This invention was made in order to solve the problems of the above-mentioned conventional supporting device, and it is possible to reduce the necessary strength for the axle and to support the wheel with high accuracy because the bearing clearance after installation is small. An object of the present invention is to provide a wheel support device that can be used.

【0009】[0009]

【課題を解決するための手段】[Means for Solving the Problems]

上記の課題を解決するため、この考案は、車軸管から露出する車軸の端部周面 に、車輪を装着するハブと、軸受の内輪を軸方向に並列して嵌合させ、上記内輪 の外周面と、その内輪の外側に嵌合させた外輪の内周面に、それぞれ径方向に対 向する複列の転走面を設け、この対向する各転走面の間に複数の転動体を組込み 、上記外輪の外周面に、外輪を車輪管に固定する取付け用フランジを一体に形成 した構造としたのである。 In order to solve the above-mentioned problems, the present invention relates to the outer peripheral surface of the inner ring, in which the hub for mounting the wheel and the inner ring of the bearing are fitted in parallel in the end peripheral surface of the axle exposed from the axle tube. The surface and the inner peripheral surface of the outer ring fitted to the outer side of the inner ring are provided with double rows of rolling surfaces that face each other in the radial direction, and a plurality of rolling elements are provided between the facing rolling surfaces. The structure is such that the mounting flange for fixing the outer ring to the wheel tube is integrally formed on the outer peripheral surface of the outer ring.

【0010】 なお、上記の構造において、上記ハブを、軸方向の移動を許容する回り止め手 段を介して車軸に連結し、そのハブと車軸の周面に設けた突出部との間で上記内 輪を締付けるようにしてもよい。In the above structure, the hub is connected to the axle via a rotation stopping means that allows axial movement, and the hub is connected to the protrusion provided on the circumferential surface of the axle. The inner ring may be tightened.

【0011】[0011]

【作用】[Action]

上記構造の支持装置においては、外輪を取付け用フランジを用いて車軸管に固 定し、ハブと内輪を共に車軸に固定する。この構造では、エンジントルクは車軸 とハブを介して車輪に伝達されるが、車輪から車軸に加わるスラスト荷重やモー メント荷重は、ハブを介して軸方向に並列した外輪と内輪とから成る軸受で受け 止められる。このため、車軸には直接車輪からのスラスト荷重や曲げモーメント が作用せず、車軸の軸径を小さく設定することができる。また、フランジと車軸 は別体構造のため、各々の加工性が向上する。 In the supporting device having the above structure, the outer ring is fixed to the axle tube by using the mounting flange, and both the hub and the inner ring are fixed to the axle. In this structure, the engine torque is transmitted to the wheels via the axle and hub, but the thrust load and moment load applied from the wheels to the axle are generated by the bearing consisting of the outer and inner rings that are axially aligned via the hub. Be accepted. Therefore, the axle is not directly subjected to the thrust load or bending moment from the wheels, and the axle diameter of the axle can be set small. Also, since the flange and axle are separate structures, the workability of each is improved.

【0012】 また、軸受の外輪が取付け用フランジを介して車軸管に固定されるため、外輪 を車軸管に直接圧入する構造に比べて、組込み後の軸受に残留するすきま量を小 さくすることができる。Further, since the outer ring of the bearing is fixed to the axle tube via the mounting flange, the amount of clearance remaining in the bearing after assembly is smaller than that of the structure in which the outer ring is directly press-fitted into the axle tube. You can

【実施例】【Example】

図1は実施例の車輪支持装置を示している。 車軸1の端部には、奥側から順に肩部14、ランド部15、セレーション部1 6、及びねじ部17が形成され、ランド部15から先端側の部分が車軸管2の端 部から露出している。 FIG. 1 shows a wheel support device of the embodiment. A shoulder portion 14, a land portion 15, a serration portion 16 and a screw portion 17 are formed on the end portion of the axle 1 in this order from the back side, and a portion on the tip side from the land portion 15 is exposed from the end portion of the axle tube 2. is doing.

【0014】 上記セレーション部16には、ハブ3の円筒部19が嵌合され、そのハブ3の 前端に、車輪(図示略)を装着するためのフランジ18が一体に形成されている 。A cylindrical portion 19 of the hub 3 is fitted to the serration portion 16, and a flange 18 for mounting a wheel (not shown) is integrally formed on the front end of the hub 3.

【0015】 また、上記ランド部15の外周には、軸受の内輪4が嵌合されている。この内 輪4は、軸方向に分割可能な2つのリング部材6、7から形成され、その各リン グ部材6、7の外周面に、それぞれボールの転走面8、9が形成されている。The inner ring 4 of the bearing is fitted on the outer periphery of the land portion 15. The inner ring 4 is formed of two ring members 6 and 7 that can be divided in the axial direction, and ball rolling surfaces 8 and 9 are formed on the outer peripheral surfaces of the ring members 6 and 7, respectively. .

【0016】 一方、内輪4の外側には外輪5が嵌合され、その外輪5の内周面に、上記内輪 4の転走面8、9と径方向に対向する複列の転走面10、11が形成されている 。この対向する内外輪の転走面8、10と転走面9、11の間には、それぞれ保 持器20で保持される複数のボール12が組込まれており、この各転走面8、1 0及び9、11とボール12との間で、互いに反対方向のスラスト荷重を受け止 める複列のアンギュラ玉軸受を構成している。On the other hand, the outer ring 5 is fitted on the outer side of the inner ring 4, and the inner peripheral surface of the outer ring 5 has a double row of rolling surfaces 10 radially opposed to the rolling surfaces 8 and 9 of the inner ring 4. , 11 are formed. Between the rolling surfaces 8 and 10 and the rolling surfaces 9 and 11 of the inner and outer wheels facing each other, a plurality of balls 12 respectively held by a retainer 20 are incorporated. Between 10 and 9, 11 and the ball 12, a double row angular contact ball bearing that receives thrust loads in mutually opposite directions is configured.

【0017】 また、外輪5の外周面には、取付け用フランジ13が一体に形成され、その取 付け用フランジ13が、車軸管2の端部に設けたフランジ21にボルト22を介 して固定されるようになっている。A mounting flange 13 is integrally formed on the outer peripheral surface of the outer ring 5, and the mounting flange 13 is fixed to a flange 21 provided at an end portion of the axle tube 2 via a bolt 22. It is supposed to be done.

【0018】 また、外輪5の内周面の両端部には、内輪4の外周面とのすき間を塞ぐシール 部材23、24が取付けられ、このシール部材23、24により軸受内部が外部 から密封されている。Sealing members 23 and 24 are provided at both ends of the inner peripheral surface of the outer ring 5 to close a gap between the outer ring 5 and the outer peripheral surface. The seal members 23 and 24 seal the inside of the bearing from the outside. ing.

【0019】 上記の構造で成る実施例の支持装置においては、車軸1のねじ部17にねじ込 んだナット25により、ハブ3を軸方向に押圧し、ハブ3と内輪4を車軸1の肩 部14に締付けて固定する。また、外輪5を、取付け用フランジ13とボルト2 2を用いて車軸管2に固定する。In the supporting device of the embodiment having the above structure, the hub 3 is axially pressed by the nut 25 screwed into the threaded portion 17 of the axle 1 so that the hub 3 and the inner ring 4 are shouldered to the axle 1. Tighten and fix to part 14. Further, the outer ring 5 is fixed to the axle tube 2 by using the mounting flange 13 and the bolt 22.

【0020】 この組込み状態では、車軸1に加えられたエンジントルクはセレーション部1 6とハブ3を介して車輪に伝達される。また、車輪から車軸1に向かう荷重、す なわち車重によるラジアル荷重や、自動車が旋回することによるスラスト荷重及 びモーメント荷重は、ハブ3を介してそのハブ3と車軸管2の間に介在する軸受 (内輪4、外輪5、ボール12により構成される)により受け止められる。した がって、車軸1には直接車輪からのスラスト荷重や曲げモーメントが作用しない 。In this assembled state, the engine torque applied to the axle 1 is transmitted to the wheels via the serration portion 16 and the hub 3. Further, the load from the wheel toward the axle 1, that is, the radial load due to the vehicle weight, and the thrust load and the moment load due to the turning of the automobile are interposed between the hub 3 and the axle tube 2 via the hub 3. It is received by a bearing (composed of the inner ring 4, the outer ring 5, and the balls 12). Therefore, thrust load and bending moment from the wheels do not act on the axle 1 directly.

【0021】 上記のように組込まれる実施例の装置においては、軸受の組込み前後で軸受す きまに影響を与えるものは、ナット25によるハブ3と内輪4の締結及び内輪4 とハブ3の圧入だけとなり、これは外輪を直接圧入嵌合する場合の影響に比べて 極めて小さいため、結果的に組込み後の残留すきまの範囲を小さくすることがで きる。また、ナット25の締付け力を変化させることにより、軸受に対する予圧 調整が簡単に行なえる。In the apparatus of the embodiment incorporated as described above, the only things that affect the bearing clearance before and after the bearing is assembled are the fastening of the hub 3 and the inner ring 4 by the nut 25 and the press fitting of the inner ring 4 and the hub 3. Since this is much smaller than the effect of directly press-fitting the outer ring, the range of residual clearance after assembly can be reduced as a result. Also, by changing the tightening force of the nut 25, the preload adjustment on the bearing can be easily performed.

【0022】 また、車軸1とハブ3を別体で形成できるので、図2に示す従来の一体構造に 比べて車軸1やハブ3の製造や組立てが容易にでき、車軸1の加工精度やハブ3 の車輪取付け部分の振れ精度を高い精度に入れることができる。Since the axle 1 and the hub 3 can be formed separately, the axle 1 and the hub 3 can be manufactured and assembled more easily than the conventional integrated structure shown in FIG. 2, and the processing accuracy of the axle 1 and the hub 3 can be improved. The runout accuracy of the wheel mounting portion of 3 can be entered with high accuracy.

【0023】 なお、上述した実施例では、車軸1とハブ3を支持する軸受として、内輪4と 外輪5の間にボール12を組込んだ複列のアンギュラ玉軸受を示したが、この軸 受は両方向のスラスト荷重を受けられる構造であれば任意の構造のものを採用す ることができ、例えば複列の円すいころ軸受とすることができる。In the embodiment described above, the double row angular ball bearing in which the balls 12 are incorporated between the inner ring 4 and the outer ring 5 is shown as a bearing for supporting the axle 1 and the hub 3. Can have any structure as long as it can receive thrust loads in both directions. For example, a double row tapered roller bearing can be used.

【0024】 また、ハブ3を車軸1に連結する回り止め手段は、上述したセレーションの他 に、スプラインや、キーとキー溝の組合せ構造などとすることもできる。In addition to the serration described above, the detent means for connecting the hub 3 to the axle 1 may be a spline or a combination structure of a key and a key groove.

【効果】【effect】

以上のように、この考案は、ハブと軸受を軸方向に並列させ、軸受の外輪を取 付け用フランジにより車軸管に固定し、車輪から加わるモーメント荷重やスラス ト荷重を軸受で受けるようにしたので、車軸に対する必要強度を低く設定するこ とができ、車軸の軸径の縮小による装置のコンパクトを図ることができる。 As described above, in this invention, the hub and the bearing are arranged in parallel in the axial direction, the outer ring of the bearing is fixed to the axle tube by the mounting flange, and the moment load and thrust load applied from the wheel are received by the bearing. Therefore, the required strength for the axle can be set low, and the device can be made compact by reducing the axle diameter of the axle.

【0026】 また、外輪を取付け用フランジを用いて固定し、車軸管に対して圧入しないの で、内外輪を圧入嵌合する従来構造に比べて組込み後の軸受の残留すきまを小さ くでき、軸受の性能向上と組込み作業性の向上を実現することができる。Since the outer ring is fixed using the mounting flange and is not press-fitted into the axle tube, the residual clearance of the bearing after assembly can be made smaller than that of the conventional structure in which the inner and outer rings are press-fitted. It is possible to improve the performance of the bearing and the workability of assembling.

【0027】 さらに、ハブと車軸とを別体に形成できるので、ハブと車軸の製作が容易にな り、加工精度や組立て精度を向上させることができる。Further, since the hub and the axle can be formed separately, the hub and the axle can be easily manufactured, and the processing accuracy and the assembly accuracy can be improved.
