ラケツト１７に球継手１８で枢着連結してあると
共に、該サスペンシヨンシリンダ１５と前記アー
ム１１とは略90度に連結されかつ前記球継手１４
と球継手１８はイコライザバ中心９ａに対して前
後方向略等距離に位置している。 One end of an arm 11 is pivotally attached to the longitudinal center of the equalizer bar 9 via a pin 12 so as to be able to swing up and down, and the other end of the arm 11 is located at a position closer to the front of the rear axle 7F of the vehicle body 1. The fixed side 15a of the suspension cylinder 15 is pivotally connected to a bracket 13 provided in the arm 11 by a ball joint 14, and the fixed side 15a of the suspension cylinder 15 is connected to a ball joint 16 at a position near one end of the arm 11.
The movable side 15b is pivotally connected by a ball joint 18 to a bracket 17 provided at a rearward position from the front axle 7F of the vehicle body 1, and the suspension cylinder 15 and the arm 11 are connected by a ball joint 18. are connected at approximately 90 degrees and the ball joint 14
The ball joint 18 is located at approximately the same distance from the equalizer bar center 9a in the front-rear direction.
２０Ｆ，２０Ｒはアクスル７Ｆ，７Ｒ上部と車
体１前後とに亘つて前後方向に傾いて球継手２
１，２２でそれぞれ枢着連結した水平方向のロツ
ドである。 20F and 20R are ball joints 2 that are tilted in the front and back direction across the top of axles 7F and 7R and the front and rear of the vehicle body 1.
These are horizontal rods that are pivotally connected at 1 and 22, respectively.
なお、以上の実施例ではアクスル７の横方向一
側についてのみ説明したが、他側にも同様な懸架
装置６が設けてある。 In the above embodiment, only one side of the axle 7 in the lateral direction has been described, but a similar suspension device 6 is provided on the other side as well.
しかして、一方の駆動輪５Ｆに上向の衝撃力が
作用するとイコライザバ９、アーム１１を介して
サスペンシヨンシリンダ１５に伝播し吸収緩和さ
れる。 Therefore, when an upward impact force acts on one drive wheel 5F, it is transmitted to the suspension cylinder 15 via the equalizer bar 9 and the arm 11, where it is absorbed and alleviated.
また、一対のアクスル７Ｆ，７Ｒをイコライザ
バ９で枢着連結したから一対のアクスル７Ｆ，７
Ｒに異なる荷重が作用しても等分に支持すること
になり荷重等分機能を有する。 In addition, since the pair of axles 7F, 7R are pivotally connected by the equalizer bar 9, the pair of axles 7F, 7
Even if different loads are applied to R, it is equally supported and has the function of equally dividing the load.
また、アーム１１とサスペンシヨンシリンダ１
５の連結点とアーム１１、サスペンシヨンシリン
ダ１５の車体１の連結点とは略二等辺三角形頂点
位置となつているからサスペンシヨンシリンダ１
５に作用する荷重が軽減しサスペンシヨンシリン
ダ１５の径を小さくして小型コンパクトとでき
る。 Also, arm 11 and suspension cylinder 1
5 and the connection point of the arm 11 and the suspension cylinder 15 to the vehicle body 1 are approximately at the vertices of an isosceles triangle, so the suspension cylinder 1
The load acting on the suspension cylinder 5 is reduced, and the diameter of the suspension cylinder 15 is reduced, making it possible to make the suspension cylinder 15 smaller and more compact.
また、アクスル７Ｆ，７Ｒと車体１とにはロツ
ド２０Ｆ、２０Ｒが傾めに枢着連結してあるから
横荷重、トルク反力が支承できると共に、その構
造が簡単となる。 Further, since the rods 20F, 20R are pivotally connected to the axles 7F, 7R and the vehicle body 1 at an angle, the lateral load and torque reaction force can be supported, and the structure is simple.
また、レバ１１とイコライザバ９との枢着部以
外の枢着部は全て球継手となつているから各部材
に加わる曲げモートを軽減でき、各部材の剛性を
低下できるから各部材の重量を低減できる。 In addition, since all pivot joints other than the joint between the lever 11 and the equalizer bar 9 are ball joints, the bending moment applied to each member can be reduced, and the rigidity of each member can be reduced, so the weight of each member can be reduced. Can be reduced.
本発明は以上のようになり、一対のアクスル７
Ｆ，７Ｒに作用する衝撃荷重を吸収できると共
