Description
【考案の詳細な説明】 本考案は大揺動角型揺動アームに関する。[Detailed explanation of the idea] The present invention relates to a large swing angle type swing arm.
車両用サスペンシヨンアームの如き揺動アーム
は、車体側に固定された揺動軸に弾性ブツシユを
介して支持されていたため、上記弾性ブツシユの
弾性変形分だけしか揺動し得ず、大揺動角を得る
ことができないという不都合があつた。 A swing arm such as a suspension arm for a vehicle is supported by a swing shaft fixed to the vehicle body via an elastic bushing, so it can swing only by the amount of elastic deformation of the elastic bushing, resulting in large swings. There was the inconvenience of not being able to obtain the horn.
本考案は斯かる不都合を有効に解消すべく成さ
れたもので、その目的とする処は、大揺動角が得
られるとともに、各弾性ブツシユの弾性変形を抑
えて捩れ耐久性を増大し得、更には軸直角のばね
定数を高めることができる大揺動角型揺動アーム
を提供するにある。 The present invention was developed to effectively eliminate such inconveniences, and its purpose is to obtain a large swing angle, suppress elastic deformation of each elastic bushing, and increase torsional durability. Another object of the present invention is to provide a large swing angle type swing arm that can increase the spring constant perpendicular to the axis.
斯かる目的を達成すべく本考案は、揺動アーム
を、固定側に弾性ブツシユを介して支承される軸
に、弾性ブツシユを介して支持せしめたことをそ
の要旨とする。 In order to achieve this object, the gist of the present invention is that the swing arm is supported via an elastic bush on a shaft supported on the stationary side via an elastic bush.
以下に本考案の好適一実施例を添付図面に基づ
いて詳述する。 A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.
第１図は本考案に係る揺動アームの一部破断平
面図、第２図は第１図２−２線断面図、第３図は
同揺動アームの分解斜視図である。 FIG. 1 is a partially cutaway plan view of a swing arm according to the present invention, FIG. 2 is a sectional view taken along line 2-2 in FIG. 1, and FIG. 3 is an exploded perspective view of the swing arm.

されている。更に揺動軸１の中央には揺動アーム
９がそのボス部９ａとカラー４間に介在する弾性
ブツシユ１０を介して支持されている。 In the figure, 1 is the swing axis, which is the bolt 2
The bolt 2 is constructed by inserting the collars 3, 4, and 5 into the bolt 2, and tightening a nut 6 that is threaded onto the end of the bolt 2. The swing shaft 1 is supported on the fixed side via elastic bushes 8, 8 interposed between collars 3, 5 at both ends thereof and a bracket 7 fixed on the fixed side. Furthermore, a swing arm 9 is supported at the center of the swing shaft 1 via an elastic bush 10 interposed between its boss portion 9a and the collar 4.
而して揺動アーム９はまず揺動軸１に対しては
弾性ブツシユ１０の弾性限度まで角度θ1だけ揺動
し得る。そして、弾性ブツシユ１０が通性限度に
達した後は揺動アーム９と揺動軸１とは一体に回
動するようになり、これら１，９は弾性ブツシユ
８，８が弾性限度に達するまで更に角度θ2だけ回
動し得る。 Thus, the swing arm 9 can first swing by an angle θ 1 with respect to the swing shaft 1 up to the elastic limit of the elastic bush 10 . After the elastic bushing 10 reaches its permeability limit, the swinging arm 9 and the swinging shaft 1 begin to rotate together, and these 1 and 9 rotate until the elastic bushings 8 and 8 reach their elasticity limit. It can further rotate by an angle θ 2 .
以上の結果、揺動アーム９は弾性ブツシユ８，
８，１０が弾性限度に達するまで角度θ1＋θ2だけ
揺動することができ、従来に比しその揺動角が大
幅に大きくなる。 As a result of the above, the swing arm 9 has the elastic bush 8,
8 and 10 can swing by an angle θ 1 +θ 2 until they reach their elastic limits, and the swing angle is significantly larger than in the past.
又従来のものに比し、同一揺動角に対して各弾
性ブツシユ８，８，１０のねじれ変形は少なくて
済み、このため各弾性ブツシユ８，８，１０の捩
れ耐久性は著しく向上する。 Moreover, compared to the conventional one, the torsional deformation of each elastic bush 8, 8, 10 is reduced for the same swing angle, and therefore the torsional durability of each elastic bush 8, 8, 10 is significantly improved.

０８，１０８を介して固定側に支承されている。 4 and 5 are a plan sectional view and an exploded perspective view of a swing arm according to a modified embodiment of the present invention. Also in this modified embodiment, a swing shaft 101 is attached to a bolt 102 with collars 103, 104, 105. It is integrally constructed by inserting it through and tightening it with a nut 106. This swing shaft 101 is connected to the elastic bush 1.
It is supported on the fixed side via 08 and 108.
一方、揺動アーム１０９は二股状に成形され、
これは弾性ブツシユ１１０，１１０を介して前記
揺動軸１０１に支持されている。尚本実施例の場

０８，１０８，１１０，１１０が直列に配列され
ている。 On the other hand, the swing arm 109 is formed into a bifurcated shape,
This is supported by the swing shaft 101 via elastic bushes 110, 110. In the case of this embodiment, four elastic bushes 1 are connected to the swing shaft 101.
08, 108, 110, and 110 are arranged in series.
而して本変更実施例においても前記第一実施例
にて得られたと同様の効果を得ることができる。 In this modified embodiment, the same effects as those obtained in the first embodiment can be obtained.

ことができる。 As is clear from the above explanation, according to the present invention, the swinging arm is supported via an elastic bushing on the shaft supported via the elastic bushing on the fixed side, so that the swinging angle of the swinging arm is increased. This makes it possible to improve the torsional durability of each elastic bushing.
