Description
本発明は、自動車で使用される、継手装置(a joint arrangement)、特に等速ジョイントまたはトリポード型ジョイント(a tripod joint)であって、継手ハウジングと、継手ハウジングに固定して接続されている入力シャフトと、トリポード軸受アセンブリ(a tripod bearing assembly)によって結合して回転するように継手ハウジングに配置されている接合シャフトとを有し、入力シャフトおよび接合シャフトを互いに接続する曲げ弾性接続機構が設けられ、曲げ弾性接続機構が、第1固定領域によって入力シャフトに接続され、第2固定領域によって接合シャフトに接続されている、継手装置に関する。 The invention relates to a joint arrangement, in particular a constant velocity joint or a tripod joint, used in motor vehicles, the joint housing and an input fixedly connected to the joint housing There is provided a bending elastic connecting mechanism for connecting the input shaft and the joining shaft to each other, the shaft having a joining shaft disposed in the joint housing to be coupled and rotated by a tripod bearing assembly. The bending elastic connection mechanism is related to the joint device connected to the input shaft by the first fixed region and connected to the joint shaft by the second fixed region.
これらの継手装置には多くの用途があり得る。自動車では、この種の継手装置は、特に等速(homokinetic)動力伝達装置で使用されており、そこでは、たとえばモーターレースにおいて大きい動力が伝達されなければならない。ここでの一用途では、動力伝達装置の出力軸は、この種の継手装置によって接合シャフトに接続され、接合シャフトはホイールハブに結合されている。 These coupling devices can have many uses. In motor vehicles, this type of coupling device is used in particular in a homokinetic power transmission device, where large power must be transmitted, for example in motor racing. In one application here, the output shaft of the power transmission device is connected to the joint shaft by this type of joint device, which is coupled to the wheel hub.
下記特許文献1は、入力シャフトと接合シャフトとの間に曲げ弾性接続部材を提供する継手装置を開示しており、これは、可動性を保証するように意図されており、曲げ弾性接続部材は、入力シャフトと接合シャフトとの両方に配置されている。曲げ弾性接続部材は、この場合、曲げ弾性金属ケーブルであるか、または曲げ弾性プラスチックロッドであり得る。しかしながら、両実施形態には、特に大きい内向きおよび外向きの偏り走行ならびに急な操舵移動の場合に、過度の曲げ荷重が接続機構の寿命に対して悪影響を及ぼすという不都合がある。 The following patent document 1 discloses a joint device that provides a bending elastic connecting member between an input shaft and a joining shaft, which is intended to ensure mobility, and the bending elastic connecting member is , Arranged on both the input shaft and the joining shaft. The bending elastic connecting member can in this case be a bending elastic metal cable or a bending elastic plastic rod. However, both embodiments have the disadvantage that excessive bending loads adversely affect the life of the connection mechanism, especially in the case of large inward and outward biased travel and sudden steering movements.
したがって、本発明の目的は、上述した不都合を回避し、非常に高い荷重に耐えることができると同時に、接合シャフトが破損するのを確実に防止する、継手装置を提供することである。 Accordingly, it is an object of the present invention to provide a coupling device that avoids the above-mentioned disadvantages and can withstand very high loads, while at the same time reliably preventing the joint shaft from being damaged.
この目的は、第2固定領域が、接合シャフトの方向においてトリポード軸受アセンブリの中心点から間隔を空けて配置されているという事実によって達成される。この単純かつ低コストの方法により、接続機構における曲げ荷重を大幅に低減することができ、従来のように「S字型偏向」が引き起こされる可能性はない。 This object is achieved by the fact that the second fixed region is spaced from the center point of the tripod bearing assembly in the direction of the joining shaft. With this simple and low-cost method, the bending load in the connection mechanism can be greatly reduced, and there is no possibility of causing “S-shaped deflection” as in the prior art.
有利な実施形態では、第1固定領域に対し、スリーブの形態の第1固定装置を設けることができる。さらに、入力シャフトに向かって開放している漏斗状要素を有するスリーブの形態の第2固定装置を設けることができる。 In an advantageous embodiment, a first fixing device in the form of a sleeve can be provided for the first fixing region. Furthermore, a second fixing device in the form of a sleeve having a funnel-like element that opens towards the input shaft can be provided.
第1の有利な実施形態では、曲げ弾性接続機構が、第1固定領域および第2固定領域によって固定されている曲げ弾性ロッド部材を有していることが有利であることが分かった。曲げ弾性を向上させるために、曲げ弾性接続機構に対して軸方向に予荷重が加えられると有利である。この場合、曲げ弾性接続機構はまたケーブル部材を有することができ、それは第1固定領域および第2固定領域によって固定されている。この場合特に、ねじ継手によって固定領域に接続されかつ入力シャフトの軸方向面に支持されている、引張要素が設けられることが有利であることが分かった。 In a first advantageous embodiment, it has been found advantageous that the bending elastic connection mechanism comprises a bending elastic rod member which is fixed by a first fixing region and a second fixing region. In order to improve the bending elasticity, it is advantageous if a preload is applied axially to the bending elastic connection mechanism. In this case, the bending elastic connection mechanism can also have a cable member, which is fixed by the first fixing region and the second fixing region. In this case, in particular, it has proven to be advantageous to provide a tension element which is connected to the fixing region by a threaded joint and supported on the axial face of the input shaft.
本発明について、以下、図面を参照してより詳細に説明する。 Hereinafter, the present invention will be described in more detail with reference to the drawings.
図1は、自動車(特に図示せず)で使用される、本発明による継手装置2の断面図を示す。図示する継手装置2を使用して、特にホイールハブ(図示せず)を自動車の動力伝達装置に接続する。この目的で、継手装置2はトリポードハウジング(a tripod housing)4を有し、それは、対象としている実施形態では入力シャフト6に一体的に連結されており、入力シャフト6は、動力伝達装置の出力シャフトを表すことができる。継手ハウジング4に、接合シャフト8が既知の方法で配置されており、関節が、トリポード軸受アセンブリ10によって提供されている。この場合、ダイアフラム12が、継手ハウジング4の可撓性封止を確実にする。
FIG. 1 shows a cross-sectional view of a coupling device 2 according to the invention for use in a motor vehicle (not specifically shown). The coupling device 2 shown is used to connect in particular a wheel hub (not shown) to the power transmission device of the vehicle. For this purpose, the coupling device 2 has a tripod housing 4, which in the intended embodiment is integrally connected to the
接合シャフト8の高い位置決め(中心位置決め)精度と組み合わされた高度な可動性を確実にするために、曲げ弾性接続機構14が設けられている。対象としている実施形態では、この曲げ弾性接続機構14はケーブル18から構成され、ケーブル18は、第1固定領域20によって入力シャフト6に、かつ第2固定領域21によって接合シャフト8に接続されている。ケーブル18を、曲げ弾性を有するロッド状要素によって置き換えることも可能であることが明らかなはずである。対象としている実施形態では、ケーブル18の曲げ弾性は、引張要素22が設けられ、前記引張要素が、スリーブ24によってケーブル18の第1固定領域20に固定して接続されているという事実によってもたらされる。引張要素22は、入力シャフト6内を通され、予荷重を加えることができるように、入力シャフト6の軸方向面26に既知の方法で支持されている。
In order to ensure a high degree of mobility combined with a high positioning (center positioning) accuracy of the joining shaft 8, a bending elastic connection mechanism 14 is provided. In the subject embodiment, the flexural elastic connection mechanism 14 comprises a cable 18 that is connected to the
ケーブル18の第2固定領域21は、第2固定装置28に固定されており、第2固定装置28は、入力シャフトに向かって開放している漏斗状要素30を有するスリーブの形態で具現化されており、固定装置28は、保持ワッシャ32によって接合シャフト8に軸方向に固定されている。
The
第2固定領域21は、接合シャフト8の方向において入力シャフト6から離れている側に、トリポード軸受アセンブリ10の中心点から間隔を空けて配置されている。それにより、曲げ弾性接続機構14に対する曲げ荷重を大幅に低減することができる。
