The relationship between torsional torque and rotation angle is shown in the figure. 9 is shown in characteristic line U. The rising portion U1 of the characteristic line U in FIG. 8 has a stopper function. This is the area where it is expressed.
【００１８】 このとき本実施例では、前記した様に隙間３８は径内側が隙間幅Ｔ１と小さく 、径外側が隙間幅Ｔ２と大きな形状にされているので、ワッシャー部材５の当板 部５１のストッパ面５５が溝側壁面３６に線接触し易くなり、当接面積が増し、 当接時の衝撃を緩和でき、よって溝側壁面３６の樹脂部分の保護に有利である。 また本実施例では図１に示す様に、溝側壁面４６とワッシャー部材５の中央板 部５３との隙間４８の隙間幅Ｔ３は前記した隙間幅Ｔ２よりも大きくされている 。従ってワッシャー部材５の中央板部５３の側辺５３ｃが溝側壁面４６に接触す るよりも先に、ワッシャー部材５の当板部５１のストッパ面５５が溝側壁面３６ に確実に接触することになる。[0018] At this time, in this embodiment, as described above, the radially inner side of the gap 38 is small with the gap width T1. , since the radially outer side has a large shape with a gap width T2, the abutment plate of the washer member 5 The stopper surface 55 of the portion 51 easily comes into line contact with the groove side wall surface 36, increasing the contact area, The impact at the time of contact can be alleviated, which is advantageous for protecting the resin portion of the groove side wall surface 36. Further, in this embodiment, as shown in FIG. 1, the groove side wall surface 46 and the center plate of the washer member 5 are The gap width T3 of the gap 48 with the portion 53 is made larger than the above-mentioned gap width T2. . Therefore, the side 53c of the center plate portion 53 of the washer member 5 is in contact with the groove side wall surface 46. Before the stopper surface 55 of the contact plate portion 51 of the washer member 5 touches the groove side wall surface 36, will definitely come into contact with.
【００１９】 また図１から理解できる様に、剛体３の軸直角方向つまり矢印Ｙ１方向に一方 の軸７０と他方の軸７５とが相対変位したときには、ワッシャー部材５の当板部 ５１の円弧面５１ａが剛体３の外枠部３０の内周面３０ｃに当接するので、軸直 角方向におけるストッパ機能も得られる。 以上説明した様に本実施例によれば、剛体３の軸端面３ａ、３ｂに溝室３５を 形成し、溝３５にワッシャー部材５を配置しているので、大トルク入力時には、 溝室３５内に配置したワッシャー部材５は溝側壁面３６と当接し、剛体３の周方 向つまり捩じり方向におけるストッパ機能が発現される。そのため本実施例では 、図１０に示す従来装置で必要とされていた半径が剛体１０６の半径とほぼ等し い大型円板状のワッシャー部材２０８を必要せずとも、また、ワッシャー部材２ ０８と当接するために、従来必要とされていた複数個の樹脂カラー２０５も必要 とせずとも、ストッパ機能が得られ、したがって軽量化、コストの面で有利であ る。特に本実施例にかかるワッシャー部材５と図１０に示す従来のワッシャー部 材２０８とを比較すると、剛体のサイズが同じとすると、本実施例にかかるワッ シャー部材５は小型、軽量で済む。[0019] Also, as can be understood from Figure 1, one side is perpendicular to the axis of the rigid body 3, that is, in the direction of arrow Y1. When the shaft 70 of the washer member 5 and the shaft 75 of the other shaft are relatively displaced, the abutment plate portion of the washer member 5 Since the arcuate surface 51a of 51 contacts the inner circumferential surface 30c of the outer frame portion 30 of the rigid body 3, the A stop function in the angular direction is also obtained. As explained above, according to this embodiment, the groove chambers 35 are provided on the shaft end faces 3a, 3b of the rigid body 3. Since the washer member 5 is arranged in the groove 35, when a large torque is input, The washer member 5 disposed in the groove chamber 35 is in contact with the groove side wall surface 36 and is attached to the circumference of the rigid body 3. In other words, a stopper function is achieved in the torsional direction. Therefore, in this example , the radius required in the conventional device shown in FIG. 10 is almost equal to the radius of the rigid body 106. Also, the washer member 2 In order to make contact with 08, multiple resin collars 205, which were previously required, are also required. The stopper function can be obtained even without using the Ru. In particular, the washer member 5 according to this embodiment and the conventional washer part shown in FIG. Comparing with material 208, if the size of the rigid body is the same, the wax according to this example is The shear member 5 is small and lightweight.
【００２０】 ところで、図１０に示す従来装置では、樹脂カラー２０５と剛体１０６とでゴ ム弾性体１０５がその軸方向において過圧縮され、ゴム弾性体１０５の軸方向に おけるばね定数が高くなり、遮音性能が低下しがちである。この点本実施例では 図４から理解できる様に、第１取付具１の軸端１ｂの端面にワッシャー部材５の 当板部５１が当接するので、通常状態においてゴム弾性体６とワッシャー部材５ の当板部５１との間に隙間Ｓ１を確保でき、両者の非接触状態は維持される。従 ってゴム弾性体６の軸方向における過剰圧縮を回避でき、軸方向におけるばね定 数を低めに維持でき、ステアリンクギアからの振動伝達を抑え得、遮音性能の維 持に有利である。しかも隙間Ｓ１により、ゴム弾性体６の軸端の摩滅も抑え得る 。[0020] By the way, in the conventional device shown in FIG. 10, the resin collar 205 and the rigid body 106 are The rubber elastic body 105 is overcompressed in its axial direction, and the rubber elastic body 105 is overcompressed in its axial direction. The spring constant of the spring becomes high, and the sound insulation performance tends to deteriorate. In this example, As can be understood from FIG. 4, a washer member 5 is attached to the end surface of the shaft end 1b of the first fixture 1. Since the contact plate portion 51 is in contact with the rubber elastic body 6 and the washer member 5 in the normal state, A gap S1 can be secured between the contact plate portion 51 and the non-contact state between the two can be maintained. subordinate Therefore, excessive compression of the rubber elastic body 6 in the axial direction can be avoided, and the spring constant in the axial direction can be improved. The number can be kept low, suppressing vibration transmission from the steering link gear, and maintaining sound insulation performance. It is advantageous to hold. Furthermore, the gap S1 can also suppress wear on the shaft end of the rubber elastic body 6. .
【００２１】 更に本実施例では剛体３の軸端面３ａ、３ｂにリング状の外枠部３０が形成さ れているので、樹脂製の剛体３の強度確保に有利である。更に溝室３５にはリブ として機能する橋架部３７が形成されているので、強度が低下しがちの溝室３５ 付近の強度確保に有利である。特に本実施例では、図２に示す様に剛体３の軸端 面３ａ、３ｂにそれぞれ形成された溝室３５は十文字形状に配置されており、ま た、剛体３の軸端面３ａ、３ｂにそれぞれ形成された橋架部３７も十文字形状に 配置されているため、樹脂製の剛体３の強度確保に有利である。[0021] Furthermore, in this embodiment, a ring-shaped outer frame portion 30 is formed on the shaft end surfaces 3a and 3b of the rigid body 3. This is advantageous in ensuring the strength of the rigid body 3 made of resin. Furthermore, the groove chamber 35 is provided with ribs. Since the bridge portion 37 that functions as a This is advantageous in securing strength in the vicinity. In particular, in this embodiment, the shaft end of the rigid body 3 is The groove chambers 35 formed on the surfaces 3a and 3b are arranged in a cross shape, and In addition, the bridge portions 37 formed on the shaft end faces 3a and 3b of the rigid body 3 are also shaped like a cross. This arrangement is advantageous in ensuring the strength of the rigid body 3 made of resin.
