Description

この発明は、車両のプロペラシャフト用等速ジョイント装置に関する。   The present invention relates to a constant velocity joint device for a propeller shaft of a vehicle.

車両のプロペラシャフトを連結する等速ジョイントは、インナーレースを取り付ける軸部に嵌装してアウターレースの前面部に等速ジョイントをシールするブーツ（ブーツシール）を設けているが、このブーツに、等速ジョイントの発熱によるジョイント内の膨張空気によって、ブーツの凹状壁が反転して破損するのを防止するために、外部開放通気穴を設けたものがある（例えば、特許文献１）。
実開平５−０４２８３７号 The constant velocity joint that connects the propeller shaft of the vehicle is provided with a boot (boot seal) that is fitted to the shaft portion to which the inner race is attached and seals the constant velocity joint on the front portion of the outer race. In order to prevent the concave wall of the boot from being inverted and damaged by the expanded air in the joint due to heat generated by the constant velocity joint, there is one provided with an external open vent hole (for example, Patent Document 1).
Japanese Utility Model Publication No. 5-042837

しかし、等速ジョイントの内部膨張空気を、ブーツの外部開放通気穴から外部に開放する際、潤滑用のグリースも一緒に外部に漏らす可能性があり、そのため長期間使用しているうちに、グリース不足による潤滑不良を起こして、等速ジョイントの破損に至るという問題があった。   However, when releasing the internal expansion air of the constant velocity joint from the external opening vent hole of the boot to the outside, there is a possibility that the grease for lubrication may also leak to the outside. There was a problem that the lubrication failure was caused by the shortage and the constant velocity joint was damaged.

一方、ブーツの外部開放通気穴から等速ジョイントの内部に泥水等が侵入する可能性があり、そのため長期間使用しているうちに、泥水等の侵入による潤滑不良で、等速ジョイントの破損に至るという問題があった。   On the other hand, there is a possibility that muddy water may enter the constant velocity joint from the external open vent hole of the boot, so that the constant velocity joint may be damaged due to poor lubrication due to the intrusion of muddy water etc. There was a problem of reaching.

この発明は、このような問題点を解決することを目的としている。   An object of the present invention is to solve such problems.

本発明は、プロペラシャフトを連結する等速ジョイントのアウターレースの前面部に、インナーレースを取り付ける軸部に嵌装して等速ジョイントをシールするブーツシールを設けたプロペラシャフト用等速ジョイント装置において、等速ジョイントのアウターレースの隔壁の一部に、ブーツシールよりも剛性の低い低剛性隔壁を備え、等速ジョイントの内部空気が膨張する際に低剛性隔壁の変形により等速ジョイントの内部体積を増加させることを特徴とする。 The present invention relates to a constant velocity joint device for a propeller shaft, in which a boot seal is provided on a front surface portion of an outer race of a constant velocity joint for connecting a propeller shaft and fitted to a shaft portion to which an inner race is attached to seal the constant velocity joint. A part of the outer race partition of the constant velocity joint is provided with a low rigidity partition that is less rigid than the boot seal, and the internal volume of the constant velocity joint is deformed by the deformation of the low rigidity partition when the air inside the constant velocity joint expands. It is characterized by increasing.

本発明によれば、等速ジョイントの内部圧力の平衡を保ち、ブーツシールの反転による破損を防止できると共に、等速ジョイントの潤滑不良を防止できる。   According to the present invention, internal pressure balance of the constant velocity joint can be maintained, damage due to inversion of the boot seal can be prevented, and poor lubrication of the constant velocity joint can be prevented.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１、図２において、１は車両の駆動力を車軸に伝えるプロペラシャフト、２はプロペラシャフト１を連結する等速ジョイントを示す。   1 and 2, reference numeral 1 denotes a propeller shaft that transmits the driving force of the vehicle to the axle, and 2 denotes a constant velocity joint that connects the propeller shaft 1.

等速ジョイント２は、プロペラシャフト１の中間部に設け、非駆動側の中空軸部３の端部にアウターレース４を、駆動側の嵌合軸部５の端部にインナーレース６を取り付けている。   The constant velocity joint 2 is provided at an intermediate portion of the propeller shaft 1, and an outer race 4 is attached to an end portion of the non-drive side hollow shaft portion 3, and an inner race 6 is attached to an end portion of the drive side fitting shaft portion 5. Yes.

アウターレース４にスチールボール７を間にインナーレース６を嵌め合わせて、駆動側非駆動側の軸部５、３の所定の角度等の変動を許容しながら動力を伝達するようにしている。   The inner race 6 is fitted between the outer race 4 and the steel ball 7 so that power can be transmitted while allowing a predetermined angle or the like of the shafts 5 and 3 on the driving side non-driving side to be allowed to change.

アウターレース４の前面部には、等速ジョイント２をシールするブーツ（ブーツシール）８を設けている。   A boot (boot seal) 8 for sealing the constant velocity joint 2 is provided on the front surface of the outer race 4.

ブーツ８は、内筒部１０を嵌合軸部５に嵌装すると共に、内筒部１０につながる凹状壁部１１の外縁部にブーツカバー１２を取り付けて、ブーツカバー１２をアウターレース４の外周部に固定している。   The boot 8 has the inner cylinder portion 10 fitted to the fitting shaft portion 5, and a boot cover 12 is attached to the outer edge portion of the concave wall portion 11 connected to the inner cylinder portion 10, so that the boot cover 12 is attached to the outer periphery of the outer race 4. It is fixed to the part.

ブーツ８は、軸部５、３の所定の角度等の変動を許容するように弾性ならびに耐熱性を持つゴム材等（内部に金属板を用いて良い）から形成する。   The boot 8 is formed of a rubber material or the like having elasticity and heat resistance (a metal plate may be used inside) so as to allow fluctuations in the predetermined angles of the shaft portions 5 and 3.

このアウターレース４の隔壁の一部に、ブーツ８よりも剛性の低い低剛性隔壁１３を備える。   A part of the partition wall of the outer race 4 is provided with a low rigidity partition wall 13 having rigidity lower than that of the boot 8.

この場合、アウターレース４の中空軸部３に面する隔壁ならびにこの隔壁に面する中空軸部３の端部壁を円形に切り欠き、そのアウターレース４の円形の開口部１４に低剛性隔壁１３を取り付ける。   In this case, the partition wall facing the hollow shaft portion 3 of the outer race 4 and the end wall of the hollow shaft portion 3 facing this partition wall are cut out in a circular shape, and the low rigidity partition wall 13 is formed in the circular opening 14 of the outer race 4. Install.

低剛性隔壁１３は、中央部１５を中空軸部３の方向（アウターレース４の外部方向）に突出したすり鉢形状に、周縁部をフランジ状に形成して、そのフランジ部１６を介してアウターレース４の開口部１４に取り付ける。   The low-rigidity partition wall 13 is formed in a mortar shape in which the central portion 15 protrudes in the direction of the hollow shaft portion 3 (the outer direction of the outer race 4), and the peripheral portion is formed in a flange shape. 4 to the opening 14.

低剛性隔壁１３は、ブーツ８よりも剛性が低く、耐熱性を持ち、伸縮性の高いゴム材等から形成する。   The low-rigidity partition wall 13 is formed of a rubber material having a lower rigidity than the boot 8, heat resistance, and high elasticity.

このように等速ジョイント２のアウターレース４の隔壁の一部に、ブーツ８よりも剛性の低い低剛性隔壁１３を備えるので、等速ジョイント２の発熱により等速ジョイント２の内部空気が膨張する際、図３のように低剛性隔壁１３の変形により等速ジョイント２の内部体積を増加させる。   As described above, since a part of the partition wall of the outer race 4 of the constant velocity joint 2 is provided with the low-rigidity partition wall 13 having rigidity lower than that of the boot 8, the internal air of the constant velocity joint 2 is expanded by the heat generated by the constant velocity joint 2. At this time, the internal volume of the constant velocity joint 2 is increased by deformation of the low-rigidity partition wall 13 as shown in FIG.

そのため、等速ジョイント２の内部圧力の平衡を保ち、ブーツ８の凹状壁部１１の反転による破損を防止することができる。   Therefore, the internal pressure of the constant velocity joint 2 can be balanced, and damage due to inversion of the concave wall portion 11 of the boot 8 can be prevented.

したがって、従来例のように、ブーツの外部開放通気穴から潤滑用のグリースが外部に漏れたり等速ジョイントの内部に泥水等が侵入して、等速ジョイントの潤滑不良を起こすようなことを防止することができる。   Therefore, as in the conventional example, it prevents the grease for lubrication from leaking from the open vent hole of the boot or the intrusion of muddy water into the constant velocity joint, causing poor lubrication of the constant velocity joint. can do.

低剛性隔壁１３は、円形のため、等速ジョイント２の内部空気の膨張により変形する際、変形時の応力が均一化し、応力集中を防止する。   Since the low-rigidity partition wall 13 is circular, when it deforms due to the expansion of the internal air of the constant velocity joint 2, the stress at the time of deformation becomes uniform and stress concentration is prevented.

また、低剛性隔壁１３を外部方向に突出したすり鉢形状に形成してあるため、低剛性隔壁１３が変形し等速ジョイント２の内部体積が増加しても、プロペラシャフト１の回転による遠心力でグリースは低剛性隔壁１３のすり鉢形状に沿ってジョイント側に戻るようになり、等速ジョイント２の良好な潤滑を保てる。   Further, since the low-rigid partition wall 13 is formed in a mortar shape protruding outward, even if the low-rigid partition wall 13 is deformed and the internal volume of the constant velocity joint 2 is increased, the centrifugal force due to the rotation of the propeller shaft 1 is increased. The grease returns to the joint side along the mortar shape of the low-rigid partition wall 13, and good lubrication of the constant velocity joint 2 can be maintained.

一方、図２に示してあるように、低剛性隔壁１３は、中心部の肉厚を薄く、外周部に向け徐々肉厚を厚くするように形成、すなわち中心部の剛性を最も低く、外周部にかけて徐々に剛性を増す構造に形成して良い。   On the other hand, as shown in FIG. 2, the low-rigidity partition wall 13 is formed so that the thickness of the central portion is thin and the thickness is gradually increased toward the outer peripheral portion, that is, the rigidity of the central portion is the lowest, and the outer peripheral portion It may be formed into a structure that gradually increases in rigidity.

このようにすれば、プロペラシャフト１の回転による遠心力でグリースが低剛性隔壁１３を押圧することによる低剛性隔壁１３の耐久性が向上する。   In this way, the durability of the low-rigidity partition wall 13 due to the grease pressing the low-rigidity partition wall 13 with the centrifugal force generated by the rotation of the propeller shaft 1 is improved.

車両ならびに車両以外のプロペラシャフト用等速ジョイント装置に適用できる。   It can be applied to a constant velocity joint device for propeller shafts other than vehicles and vehicles.
