自動車のサスペンション装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the improvement of suspension devices for automobiles, and more specifically, to the improvement of suspension devices for automobiles. This invention relates to suspension devices for automobiles.

となどの特徴がある。As a strut type suspension device that mainly supports the front wheels of an automobile, conventionally, for example,
There is one described in Publication No. 208. This suspension system consists of a suspension arm connected to the vehicle body so that the front axle can swing vertically, a suspension damper that is fixedly attached to the arm of the front axle, and interposed between the vehicle body and the suspension arm. It consists of a suspension spring. This kind of suspension system has a simple structure, has a small number of parts, and is lightweight, has a low unsprung weight, so it provides a good ride, and compared to the Witschborn type, it does not have an upper suspension arm, so it does not require much space in the engine room. It is characterized by a spacious layout.

トが発生し、その部分に固定して設けられるロントガイ
ドを介してピストンロッドに偏向した荷重が作用する。In the strut type suspension device described above, the lower end of the suspension damper is fixedly attached to the axle, so an upward load acting on the wheel acts to deflect the suspension damper inward. Therefore, a moment is generated that pushes the upper end of the cylinder inward, and a deflected load acts on the piston rod via a front guide fixedly provided at that portion.

ング性能や耐久性の低下を来すようなことが起こる。This deflected load increases sliding resistance, causing abnormal damping action and deteriorating riding comfort. In addition, if such deflection loads are frequently applied to the front guide, abnormally uneven wear will occur on the sliding surface with the piston rod, and eventually the sealing performance will be lost and the oil inside the cylinder will leak. Damping performance and durability may deteriorate due to foreign matter entering the cylinder from the outside.
本発明は、このような事情を考慮してなされたもので、

。On the other hand, due to the upward tilting of the distal end of the suspension arm, the opening angle between the suspension arm and the suspension damper becomes large, and the link means connected therebetween becomes tense. The elastic member is deformed by the tension of the link means, the lower end of the suspension damper is pulled inward, and the inward force acting on the upper end of the cylinder is suppressed. Therefore, even when the wheels swing during a bump, a deflected load is not applied to the suspension damper.

が得られる。The automobile suspension device of the present invention is provided with a link means that connects the suspension arm and the vicinity of the attachment part of the suspension damper to the wheel support member, and the link means has an elastic member that expands and contracts with the displacement of the wheel when bumping. Since the member is interposed, a large deflection load is not applied to the suspension damper even when the wheel swings significantly during a bump or the like. Therefore, the operating condition of the suspension damper is maintained in good condition, and good riding comfort is obtained.

The elastic member 10 is made of a rubber body, has a pair of hollow portions 10a in the rod axial direction, and is deformed by shearing in response to an axial tensile load via a shaft supporting member 11 through which the connecting pin 9 is inserted. , a resilient force accompanied by a buffering effect is exerted.

When the wheel 1 is displaced more than a predetermined value, such as during a bump, the lower end of the cylinder 5b is pulled inward by the link means 8, so that no deflection load is applied to the suspension damper 5.

からない。When the car is running on a flat road, the suspension arm 7
is in a substantially horizontal state, and the link means 8 is in a relaxed state with both rods 8a and 8b bent at the central connecting portion, as shown in the lower part of FIG. In such a case, the inclination angle of the suspension damper 5 is set so that the direction of the load acting on the suspension damper 5 from the wheel 1 via the wheel support member 2 substantially coincides with its axial direction. Therefore, the cylinder 5 is placed in the piston loft 5a.
The load applied through b acts only in the axial direction, and no deflected force is exerted on the sliding surfaces of the rod guide 5C or piston 5d.

ンダンパー５には軸方向にのみ荷重がかかる。However, when an automobile travels on a road with severe unevenness and undergoes a violent rocking motion that pushes up the vehicle body 4, such as a so-called bump, the tip of the suspension arm 7 tilts upward significantly. Since the cylinder 5b is integrally fixed to the wheel support member 2, and the upper end of the piston rod 5a is pivotally supported by the vehicle body 4, the opening angle of the cylinder 5b with respect to the suspension arm 7 increases as the cylinder 5b tilts. Therefore 1.
The link means 8 is in a tensioned state as shown in the middle or upper part of the figure, and the elastic member 10 is sheared and deformed.
The lower part of the cylinder 5b is pulled inward, and a load is applied to the suspension damper 5 only in the axial direction.

引張力Ｆ＝ｋ （ｊ！＋ −１Ｏ）を発生させる。That is, when the wheel support member 2 is displaced upward by a predetermined amount or more, the piston rod 5a is moved from the upper end of the cylinder 5b by a component force S of an external force acting on the wheel 1 at the grounding point in a direction perpendicular to the axis of the suspension damper 5. Ronto Guide 5
It receives an inward force S1 through C. On the other hand, since the opening angle between the cylinder 5b and the suspension arm 7 becomes large, the link means 8 becomes tense, and an inward tension F acts on the lower end of the cylinder 5b. This tension F causes a force F1 to act on the piston rod 5a in the opposite direction to the nuclear force S+ which reduces the force S1. In such a state, the component force S
The reaction force Su from the vehicle body 4 side acting on the upper end of the piston rod 5a is similarly reduced by the opposing force Fu due to the tension F. Therefore, suspension damper 5
The force applied in the direction perpendicular to the axis of is kept approximately in equilibrium,
Most of the load from wheel 1 is transferred to suspension damper 5.
The deflection is reduced by acting along the axial direction. By the way,
Double shaft support member 11.11 in the relaxed state of the link means 8
The length lO between the two increases when under tension and becomes l+,
A tensile force F=k (j!+ -1O) is generated.

In addition, a large deflection load does not act on the rod guide, preventing uneven wear.
Since the sealing performance is maintained, suspension damper 5
The durability is improved and a good riding comfort can be maintained.

a and 8b, but the present invention does not specify the structure of the link means.In short, the link means is linked between the wheel support member and the suspension arm, and when the distance between the link points is extended beyond a predetermined value, a tensile force is applied. Therefore, for example, a single connecting rod with an elastic member as a valve bag, or a cylinder mechanism with a built-in coil spring may be used.
