【発明の詳細な説明】
（産業上の利用分野）
本発明はダブルウィツシュボーン式サスペンションに関
する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a double wishbone suspension.
（従来の技術）
車輪を支承するナックルに７シパアームとロアアームを
連結したダブルウィツシュボーン式サスペンションが知
られ、これを転舵輪用に適用する場合、従来はナックル
に対するアッパアーム及びロアアームの各連結点を結ぶ
線分がキングピン軸をなしていた。(Prior Art) A double wishbone type suspension is known in which a seven-shipper arm and a lower arm are connected to a knuckle that supports a wheel.When this is applied to a steered wheel, conventionally, each connection point of an upper arm and a lower arm to the knuckle is connected to the knuckle. The connecting line formed the kingpin axis.
（発明が解決しようとする問題点）
ところで、リヤサスペンションにダブルウィツシュボー

兼ね合いからアッパアームとナックルとの連結部を後輪
のほぼと方に近づけて配置せざるをえない、このため、
後輪を転舵輪とする場合、キングピンオフセットがポジ
ティブとなり、後輪操舵力が大きくなってしまう。(Problem to be solved by the invention) By the way, when a double wishbone type rear suspension is adopted, the connecting part between the upper arm and the knuckle is moved closer to the rear wheel due to space considerations such as the trunk room. For this reason, it is necessary to place
When the rear wheels are used as steered wheels, the king pin offset becomes positive and the rear wheel steering force increases.
そこで本発明の目的は、スペース上の都合によりアッパ

きるようにしたがダブルウィツシュボーン式サスペンシ
ョンを提供するにある。Therefore, an object of the present invention is to greatly incline the kingpin axis to eliminate kingpin offset even when the connection point between the upper arm and the knuckle must be placed close to the top of the wheel due to space constraints. To provide a double wishbone type suspension that can be maintained in a negative or negative state and ensure a reduction in steering force.
（問題点を解決するための手段）
従って本発明は、Ａ型アッパアーム（１６）の軸甫手部
（１７）をナックル（１）に連結し、几つ球面継手部（
１８）を車体（Ｂ）に連結した。(Means for Solving the Problems) Therefore, the present invention connects the shaft grip portion (17) of the A-type upper arm (16) to the knuckle (1), and provides a precise spherical joint portion (
18) was connected to the vehicle body (B).
（作用）
キングピン軸（Ｋ）が大きく傾斜するので、キングピン
オフセットがポジティブになるのを防止してゼロ乃至ネ
ガティブに維持でき、以って操舵力の軽減化が確保され
る。(Function) Since the kingpin axis (K) is largely inclined, the kingpin offset can be prevented from becoming positive and can be maintained at zero or negative, thereby ensuring reduction in steering force.
（実施例） 以下に添付図面を基に実施例を説明する。(Example) Examples will be described below based on the accompanying drawings.

３）が連結される。First of all, this suspension is applied to the rear of a vehicle with front and rear wheel steering.As shown in the drawing, the axle (4) is rotatably supported on the knuckle (1), and the drive shaft (5) is rotatably supported on the knuckle (1).
A rear wheel (7) is mounted on an axle (4) to which power is transmitted from the rear wheel through a constant velocity joint (6). Further, a lower arm (9) is connected to the lower end of the knuckle (1) via a pole joint (8), and the lower arm (9) is pivotally supported on the vehicle body (B).
B) A radius rod (11) is installed between them. Furthermore, a knuckle arm (2) that protrudes rearward is formed at the lower part of the knuckle (1), and a steering tie rod (1) is connected to this knuckle arm (2) via a pole joint (12).
3) are connected.

) A bracket (14) having front and rear support pieces (15), (15) is bolted to the upper end. The wide end (17) of the A-type upper arm (16) is exposed between the supporting pieces (15) of this bracket (14), and the tubular rubber bushing (21) is interposed between the support pieces (15) and (15). The A-type upper arm (1
Pole join the middle end (18) of 6) (23)
It is pivotally supported to the vehicle body (B) via.

力をポジティブの場合に較べて軽くすることができる。Since the double wishbone type rear suspension is constructed in this way, the line segment connecting the connection point of the lower arm (9) to the knuckle (1) and the connection point of the A-type upper arm (1B) to the vehicle body (B), that is, the pole position The line segment connecting points (8) and (23) is the kingpin axis (K). This kingpin axis (K) is highly inclined as shown in the figure, and the kingpin offset is always maintained at zero or negative. , the steering force required to steer the rear wheels (7) can be made lighter than in the case of positive steering.
