Description

【０００１】
【発明の属する技術分野】
本発明は、自動車等の駆動力伝達軸部に用いられるトリポード型等速ジョイントに関するものである。
【０００２】
【従来の技術】
一般にトリポード型等速ジョイントにおいては、ジョイント部が交差角を有する状態で使用される場合、アウタ部材の案内溝とインナ部材の各トラニオンに設けられた球面ローラとの間に相対滑り現象が生じ、これが軸方向のスラスト力を誘起し、ひいては駆動軸に振動を発生させるという問題がある。
【０００３】
このような問題を解決するために、例えば図７に示す特開平６−１３７３３９号公報に記載のものが案出されている。このものは、各トラニオン１０４に、内側ローラ１０５と、この内側ローラ１０５に対して首振り自在に嵌合されるホルダ１０６と、このホルダ１０６にニードル１０８を介して嵌合される外側ローラ１０７とを設けてなる。この構成により、アウタ部材１０１に設けられた案内溝１０２に対する外側ローラ１０７の傾きをなくして外側ローラ１０７と案内溝１０２との間に正しい転がり運動を生ずるようにし、スラスト力の誘起、ひいては振動の発生を抑えるようにしている。
【０００４】
またこのものは、内側ローラ１０５の外周面１０５ａの曲率半径をホルダ１０６の内周面１０６ａの曲率半径よりも小さく形成し、且つこれらの曲率中心をオフセットさせている。これにより、内側ローラ１０５とホルダ１０６との間の接触面積を小さくし、これらの間に生じる摩擦抵抗を低減させることができるため、スラスト力の誘起、ひいては振動の発生を更に小さく抑えることができるようになっている。
【０００５】
【発明が解決しようとする課題】
ところで上記の等速ジョイントにおいては、内側ローラ１０５とホルダ１０６とが接触する部分１０９、即ちトルク伝達する部分は、トラニオン１０４の軸回りに長軸及び軸方向に短軸を持つ楕円（以下、接触楕円という）となることが一般的に知られている。
【０００６】
またこの種の等速ジョイントでは、内側ローラ１０５とホルダ１０６との回動を滑らかに行わせるために、若干の隙間を設けることが一般的である。
従って、上記従来の等速ジョイントでは内側ローラ１０５とホルダ１０６との間に通常設けられる隙間を考慮しても、接触する部分１０９を通り且つトラニオン１０４の軸に垂直な断面（図７のＢ−Ｂ断面）において、内側ローラ１０５の外周面１０５ａとホルダ１０６の内周面１０６ａとが略同一の半径を持つ円となっているため、接触楕円の長軸を短くすることができず、接触楕円の面積をそれほど小さくすることができない。そのため、内側ローラ１０５とホルダ１０６との間に生じる摩擦抵抗を十分に小さくすることができず、スラスト力の誘起、ひいては振動の発生を抑えるには不十分であった。
【０００７】
【課題を解決するための手段】
本発明は上記の課題に鑑みなされたもので、内周に軸方向に３本の案内溝を有するアウタ部材と、前記アウタ部材の内側に同軸的に配置され且つ前記案内溝内に突出するように設けられた３本のトラニオンを有するインナ部材と、前記各トラニオンに回転自在に設けられた内側ローラと、前記内側ローラに外嵌され且つ前記案内溝内を転動する外側ローラとから構成されるトリポード型等速ジョイントにおいて、前記トラニオンの軸に垂直な断面における前記内側ローラと前記外側ローラとの間に下式に示す所定の隙間を設けたことを特徴とする。前記断面における前記内側ローラの外周面の直径をＤｉ、前記隙間をＣとすると、Ｃ／Ｄｉ≧２．５×１０ -3 が成立する。
【０００８】
更に、前記内側ローラの外周面及び前記外側ローラの内周面は真球面の一部で構成することができる。また、前記トラニオンの軸方向断面における前記内側ローラの外周面及び前記外側ローラの内周面は、前記トラニオンの軸心から等距離オフセットした曲率中心を持つように構成することも可能である。
【０００９】
【発明の実施の形態】
本発明の実施の形態を図１乃至図５に基づいて説明する。
図１及び図２は第１の実施の形態を示す。
図１及び図２において、１はアウタ部材、２はアウタ部材１の内周面に軸方向に設けられた円周上複数の案内溝、３はアウタ部材１の内側に同軸的に配置されたインナ部材、４はインナ部材３に設けられ案内溝２内に放射状に突出するトラニオン、５はニードル８を介してトラニオン４に回転自在に支承される内側ローラ、６は内側ローラ５に案内溝２内を転動可能に外嵌されている外側ローラである。
【００１０】
そして、インナ部材３はそのボス部３ａに接合された駆動軸７を介して車輪等につながり、アウタ部材１はエンジン等の動力装置側につながっている。またニードル８は、断面コ字状に形成された内側ローラ５の内周面にて保持されている。
図２に示すように、内側ローラ５の外周面５ａは半径Ｒｉ（直径Ｄｉ）の真球面の一部、外側ローラ６の内周面６ａは前記Ｒｉよりも大きな半径Ｒｏ（直径Ｄｏ）の真球面の一部でそれぞれ構成され（Ｒｏ＞Ｒｉ）、これらの中心はトラニオン４の軸心上の同位置に位置する。そして、これら内側ローラ５及び外側ローラ６の間に設けられる隙間Ｃ＝Ｄｏ−Ｄｉ＝２（Ｒｏ−Ｒｉ）は上述した通常設けられる隙間よりもかなり大きいものとなっている。
【００１１】
ここで第１の実施の形態における作用を説明する。
第１の実施の形態に係る等速ジョイントが回転する場合、図２におけるＡ−Ａ断面の一部を拡大した図３に示すように、内側ローラ５の外周面５ａと外側ローラ６の内周面６ａとが接触しトルクを伝達する。（図３では内側ローラ５と外側ローラ６とが接触する部分を拡大している。なお、この反対側に隙間Ｃ＝Ｄｏ−Ｄｉが形成されることはいうまでもない。）
また図１に示すようにジョイント部が屈曲しながら回転した場合、駆動軸７の回転に伴い、図４に示すように外側ローラ６は内側ローラ５に対して回動する。この回動により内側ローラ５と外側ローラ６との間に摩擦抵抗が生じ、この摩擦抵抗がスラスト力を誘起することとなる。
【００１２】
ところが第１の実施の形態によれば、図２及び図３に示すように、真球面の一部で形成された内側ローラ５の外周面５ａの半径Ｒｉは、同じく真球面の一部で形成された外側ローラ６の内周面６ａの半径Ｒｏよりも小さく形成されている。つまり、内側ローラ５と外側ローラ６とが接触する部分、即ち接触楕円は、トラニオン４の軸回りの長軸、トラニオン４の軸方向の短軸ともに従来のものに比べかなり小さくなっている。従って、内側ローラ５と外側ローラ６との接触楕円の面積が小さくなる、即ち、外側ローラ６が内側ローラ５に対して回動する時に発生する摩擦抵抗が低減されるため、スラスト力の誘起、ひいては振動の発生を抑制することができる。
【００１３】
図５は、伝達トルクＴ＝４００（Ｎｍ）におけるジョイント角と強制力（スラスト力の振幅）との関係を示すもので、Ｃ／Ｄｉが大きくなるほど強制力が小さくなることがわかる。
ここで、隙間Ｃと内側ローラ５の外周面５ａの直径Ｄｉの比を
Ｃ／Ｄｉ＝（Ｄｏ−Ｄｉ）≧２．５×１０−３
とすれば、図５の実線（Ｃ／Ｄｉ＝２．５×１０−３）に示すように顕著な効果が得られる。（破線は従来のものを示し、Ｃ／Ｄｉ＝１．３×１０−３である。）
しかしながら、Ｃ／Ｄｉを大きくしていくと、接触楕円の面積が小さくなり過ぎ、この部分における面圧が過度に上昇してしまう恐れがあるため、Ｃ／Ｄｉは３．０×１０−３程度を上限値とすることが望ましい。
【００１４】
次に第２の実施の形態を図６に基づいて説明する。なお、第１の実施の形態と同一の構成要素は同一の符号を付すのみで、その詳細な説明は省略する。
第２の実施の形態では図６に示すように、トラニオン４の軸方向断面における内側ローラ５の外周面５ａ及び外側ローラ６の内周面６ａの曲率中心は、トラニオン４の軸心から等距離オフセットした同位置にある。そして、内側ローラ５の外周面５ａは曲率半径Ｒｉ、外側ローラ６の内周面６ａは前記Ｒｉよりも大きな曲率半径Ｒｏで構成されている。
【００１５】
また図６のＡ’−Ａ’断面において、内側ローラ５の外周面５ａは直径Ｄｉの円、外側ローラ６の内周面６ａはＤｉよりも大きな直径Ｄｏの円となる。
ここで、内側ローラ５の外周面５ａと外側ローラ６の内周面６ａとの間に設けられる隙間Ｃ＝Ｄｏ−Ｄｉ＝２（Ｒｏ−Ｒｉ）は、第１の実施の形態と同程度である。
【００１６】
以上、本発明を実施の形態に則して説明したが、本発明は実施の形態に限定されるものではない。例えば、図７に示す等速ジョイントに適用することも可能である。
また、トラニオンの軸方向断面における内側ローラの外周面及び外側ローラの内周面の曲率半径を略同一とし且つこれらの曲率中心を所定量オフセットさせることにより、これらの間に上述した実施の形態と同等の隙間を設け、接触楕円の長軸を小さくするようにしてもよい。
【００１７】
【発明の効果】
本発明に係るトリポード型等速ジョイントによれば、トラニオンの軸に垂直な断面における内側ローラの外周面と外側ローラの内周面との間に所定の隙間を設けたので、これらの間の接触楕円の面積を小さくすることができる。従って、ジョイント部が屈曲した状態で回転した場合には、内側ローラと外側ローラとの間に生じる摩擦抵抗を小さくすることができるため、スラスト力の誘起、ひいては振動の発生を低減することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tripod-type constant velocity joint used for a driving force transmission shaft of an automobile or the like.
[0002]
[Prior art]
Generally, in a tripod type constant velocity joint, when the joint portion is used in a state having an intersection angle, a relative slip phenomenon occurs between the guide groove of the outer member and the spherical roller provided on each trunnion of the inner member, This induces an axial thrust force, which in turn causes vibration on the drive shaft.
[0003]
In order to solve such a problem, for example, a device described in Japanese Patent Application Laid-Open No. Hei 6-137339 shown in FIG. 7 has been devised. Each of the trunnions 104 includes an inner roller 105, a holder 106 that is fitted to the inner roller 105 so as to swing freely, and an outer roller 107 that is fitted to the holder 106 via a needle 108. Is provided. With this configuration, the inclination of the outer roller 107 with respect to the guide groove 102 provided in the outer member 101 is eliminated, so that a correct rolling motion is generated between the outer roller 107 and the guide groove 102, and the thrust force is induced, and the vibration is reduced. I try to suppress the occurrence.
[0004]
Further, in this device, the radius of curvature of the outer peripheral surface 105a of the inner roller 105 is formed smaller than the radius of curvature of the inner peripheral surface 106a of the holder 106, and the centers of curvature are offset. Thereby, the contact area between the inner roller 105 and the holder 106 can be reduced, and the frictional resistance generated between them can be reduced, so that the induction of thrust force and, consequently, the generation of vibration can be further reduced. It has become.
[0005]
[Problems to be solved by the invention]
In the above constant velocity joint, a portion 109 where the inner roller 105 and the holder 106 are in contact with each other, that is, a portion for transmitting torque is an ellipse having a long axis around the trunnion 104 and a short axis in the axial direction (hereinafter referred to as contact). Is generally known.
[0006]
In this type of constant velocity joint, a slight gap is generally provided in order to smoothly rotate the inner roller 105 and the holder 106.
Therefore, in the above conventional constant velocity joint, a cross section passing through the contacting portion 109 and perpendicular to the axis of the trunnion 104 (B-B in FIG. 7) even if a gap normally provided between the inner roller 105 and the holder 106 is considered. B section), since the outer peripheral surface 105a of the inner roller 105 and the inner peripheral surface 106a of the holder 106 are circles having substantially the same radius, the major axis of the contact ellipse cannot be shortened, and the contact ellipse cannot be shortened. Cannot be made so small. For this reason, the frictional resistance generated between the inner roller 105 and the holder 106 cannot be sufficiently reduced, which is insufficient to suppress the induction of the thrust force and the generation of the vibration.
[0007]
[Means for Solving the Problems]
The present invention has been made in view of the above problems, and has an outer member having three guide grooves in an axial direction on an inner periphery thereof, and an outer member coaxially disposed inside the outer member and protruding into the guide grooves. An inner member having three trunnions provided on the inner side, an inner roller rotatably provided on each of the trunnions, and an outer roller fitted on the inner roller and rolling in the guide groove. In a tripod-type constant velocity joint, a predetermined gap shown by the following formula is provided between the inner roller and the outer roller in a cross section perpendicular to the axis of the trunnion. Assuming that the diameter of the outer peripheral surface of the inner roller in the cross section is Di and the gap is C, C / Di ≧ 2.5 × 10 −3 holds.
[0008]
Further, the outer peripheral surface and inner peripheral surface of the outer roller of the inner roller may be composed of a part of a true sphere. Further, the outer peripheral surface of the inner roller and the inner peripheral surface of the outer roller in the axial cross section of the trunnion may be configured to have a center of curvature that is equidistantly offset from the axis of the trunnion.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
1 and 2 show a first embodiment.
In FIGS. 1 and 2, reference numeral 1 denotes an outer member, 2 denotes a plurality of circumferentially provided guide grooves provided in the inner peripheral surface of the outer member 1 in the axial direction, and 3 denotes a coaxial arrangement inside the outer member 1. Inner member 4 is a trunnion provided in inner member 3 and radially protruding into guide groove 2, 5 is an inner roller rotatably supported by trunnion 4 via needle 8, 6 is inner roller 5 with guide groove 2. It is an outer roller that is fitted so that it can roll inside.
[0010]
The inner member 3 is connected to wheels and the like via a drive shaft 7 joined to the boss 3a, and the outer member 1 is connected to a power unit such as an engine. The needle 8 is held on the inner peripheral surface of the inner roller 5 having a U-shaped cross section.
As shown in FIG. 2, the outer peripheral surface 5a of the inner roller 5 is part of a true spherical surface having a radius Ri (diameter Di), and the inner peripheral surface 6a of the outer roller 6 is a true radius having a radius Ro (diameter Do) larger than Ri. Each of them is composed of a part of a spherical surface (Ro> Ri), and their centers are located at the same position on the axis of the trunnion 4. The gap C = Do-Di = 2 (Ro-Ri) provided between the inner roller 5 and the outer roller 6 is much larger than the above-described normally provided gap.
[0011]
Here, the operation in the first embodiment will be described.
When the constant velocity joint according to the first embodiment rotates, as shown in FIG. 3 in which a part of the AA cross section in FIG. 2 is enlarged, the outer peripheral surface 5a of the inner roller 5 and the inner peripheral of the outer roller 6 are shown. The surface 6a contacts and transmits torque. (In FIG. 3, the portion where the inner roller 5 and the outer roller 6 come into contact is enlarged. It goes without saying that a gap C = Do-Di is formed on the opposite side.)
When the joint rotates while bending as shown in FIG. 1, the outer roller 6 rotates with respect to the inner roller 5 as shown in FIG. This rotation causes frictional resistance between the inner roller 5 and the outer roller 6, and this frictional resistance induces a thrust force.
[0012]
However, according to the first embodiment, as shown in FIGS. 2 and 3, the radius Ri of the outer peripheral surface 5a of the inner roller 5 formed by a part of the true spherical surface is also formed by a part of the true spherical surface. It is formed smaller than the radius Ro of the inner peripheral surface 6a of the outer roller 6 formed. That is, the portion where the inner roller 5 and the outer roller 6 are in contact, that is, the contact ellipse, is much smaller in both the major axis around the trunnion 4 axis and the minor axis in the axial direction of the trunnion 4 as compared with the conventional one. Accordingly, the area of the contact ellipse between the inner roller 5 and the outer roller 6 is reduced, that is, the frictional resistance generated when the outer roller 6 rotates with respect to the inner roller 5 is reduced, so that the thrust force is induced. As a result, generation of vibration can be suppressed.
[0013]
FIG. 5 shows the relationship between the joint angle and the forcing force (the amplitude of the thrust force) at a transmission torque T = 400 (Nm). It can be seen that the forcing force decreases as C / Di increases.
Here, the ratio of the gap C to the diameter Di of the outer peripheral surface 5a of the inner roller 5 is C / Di = (Do−Di) ≧ 2.5 × 10 −3
Then, a remarkable effect can be obtained as shown by the solid line (C / Di = 2.5 × 10 −3 ) in FIG. (The broken line indicates the conventional one, and C / Di = 1.3 × 10 −3 .)
However, when C / Di is increased, the area of the contact ellipse becomes too small, and the surface pressure in this portion may be excessively increased. Therefore, C / Di is about 3.0 × 10 −3. Is desirably set to the upper limit.
[0014]
Next, a second embodiment will be described with reference to FIG. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
In the second embodiment, as shown in FIG. 6, the center of curvature of the outer peripheral surface 5a of the inner roller 5 and the inner peripheral surface 6a of the outer roller 6 in the axial section of the trunnion 4 are equidistant from the axis of the trunnion 4. At the same position offset. The outer peripheral surface 5a of the inner roller 5 has a radius of curvature Ri, and the inner peripheral surface 6a of the outer roller 6 has a radius of curvature Ro larger than Ri.
[0015]
6, the outer peripheral surface 5a of the inner roller 5 is a circle having a diameter Di, and the inner peripheral surface 6a of the outer roller 6 is a circle having a diameter Do larger than Di.
Here, the gap C = Do-Di = 2 (Ro-Ri) provided between the outer peripheral surface 5a of the inner roller 5 and the inner peripheral surface 6a of the outer roller 6 is substantially the same as in the first embodiment. is there.
[0016]
As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the embodiments. For example, the present invention can be applied to a constant velocity joint shown in FIG.
Further, by making the radius of curvature of the outer peripheral surface of the inner roller and that of the inner peripheral surface of the outer roller in the axial cross section of the trunnion substantially the same and offsetting the center of curvature by a predetermined amount, the embodiment described above can be interposed therebetween. An equivalent gap may be provided to reduce the major axis of the contact ellipse.
[0017]
【The invention's effect】
According to the tripod-type constant velocity joint according to the present invention, since a predetermined gap is provided between the outer peripheral surface of the inner roller and the inner peripheral surface of the outer roller in a cross section perpendicular to the axis of the trunnion, the contact between them is provided. The area of the ellipse can be reduced. Therefore, when the joint portion rotates in a bent state, the frictional resistance generated between the inner roller and the outer roller can be reduced, so that the induction of thrust force and, consequently, the generation of vibration can be reduced. .
