いる。[Prior Art] For example, the front suspension of a front-wheel drive vehicle is constructed as shown in FIGS. 4 and 5.
In the figure, 1 is a front wheel, 2 is a strut, and 3 is an arm. One end of a tension rod 4 is connected to the arm 3, and the other end of the tension rod 4 extends forward and is connected to a bracket 7 attached to a vehicle body 6 via a suspension bush 5.

An annular groove 1 on the outer periphery of the rubbers 8 and 9
1, the tension rod 4 is activated by the drive reaction force R 1 during start acceleration.
The disadvantage is that the reaction force applied to the tension rod 4 changes the attitude of the vehicle body, causing the vehicle body 6 to rise due to a downward moment generated during braking, and causing the vehicle body 6 to sink during braking. Although measures have been taken to reduce the change in attitude due to the arrangement of the arms 3, this has resulted in deterioration of the original ride comfort and maneuverability, and unnecessary increase in costs.

Our goal is to provide suspension products that can.

いる。[Summary of the invention] In order to achieve the above object, the present invention provides a tension rod along the longitudinal direction of the vehicle body, one end of which is pivotally supported by the wheel, and the other end of which is pivotally supported by the vehicle body in front of it, and the tension rod and the vehicle body are connected to each other. The suspension bushing provided between the bushing and the bushing is characterized in that a notch is formed on the upper side of the bushing so that the stiffness of the upper side of the bushing is smaller than that of the lower side of the bushing.

る。 According to this configuration, when the bushing is compressed, the upper side of the bushing, which is weak in rigidity, contracts, and when the bushing is pulled, the upper side of the bushing similarly expands. As a result,
When the tension rod is compressed during acceleration, the upper side of the bushing contracts and the tension rod rotates upward around the bushing, thereby suppressing the nose lift of the vehicle body. Conversely, when the tension rod is pulled during deceleration, the upper side of the bushing stretches and the tension rod rotates downward around the bushing, thereby suppressing the nose dive of the vehicle body.
［実施例］

A pair of cushion rubbers 8 and 9 constituting a suspension bush are fitted into the suspension bushing 0 with a bracket 7 attached to the vehicle body 6 sandwiched therebetween. A threaded portion 21 formed at the tip of the narrow diameter portion 20
By screwing the nut 10 into the housing, the cushion rubbers 8, 9 and the bracket 7 are tightened between the nut 10 and the stepped portion 22 of the narrow diameter portion 20. 23 is Watshiya.

成されている。 Notches 2 are provided on the upper surfaces of the cushion rubbers 8 and 9.
4 are formed respectively, and when accelerating from start to finish, as shown in FIG. 2, the compression force generated on the tension rod 4 by the drive reaction force R1 compresses the inner cushion rubber 9, causing the tension rod 4 to rotate counterclockwise. The tension rod 4 is configured to be elastically deformed so as to cancel out the clockwise moment M1 generated in the tension rod 4. Further, during braking, as shown in Fig. 3, the outer cushion rubber 9 is compressed by the tensile force generated on the tension rod 4 by the braking reaction force R2 , and is elastically deformed to rotate the tension rod 4 clockwise. It is configured to cancel the counterclockwise moment M 2 that occurs in .
次に作用を述べる。 Next, we will discuss the effect.

ブツシユを交点とする反時計方向のモーメントが
発生し、これが前記車体６を浮き上がらせようと
するモーメントM1を打消すことになる。 At the time of starting acceleration, a drive reaction force R1 acts on the front wheels 3 as shown in FIG. 2, and this generates a clockwise moment M1 in the tension rod 4 with the suspension bush as the intersection point, causing the vehicle body 6 to rise. try However, at the same time, the inner cushion rubber 9 is compressed by the compression force applied to the tension rod 4, and this cushion rubber 9
is elastically deformed to compress the notch 24 side, so a counterclockwise moment is generated in the tension rod 4 with the suspension bush as the intersection point, and this causes a moment M 1 that tends to lift the vehicle body 6. It will cancel it out.
一方、制動時には第３図に示す如く前輪３には

メントM2を打消すことになる。 On the other hand, during braking, a braking reaction force R 2 acts on the front wheels 3 as shown in FIG. try However, at the same time, the outer cushion rubber 8 is compressed due to the tensile force applied to the tension rod 4.
is elastically deformed to compress the notch 24 side, so a clockwise moment is generated in the tension rod 4 with the suspension bush as a fulcrum, and this hits the moment M 2 that tends to sink the vehicle body 6. It will be erased.
従つて、アームの配置関係によることなく車体
の姿勢変化を小さく抑えることができ、操縦安定
性及び乗心地の向上を図ることができる。 Therefore, changes in the posture of the vehicle body can be kept to a small level regardless of the arrangement of the arms, and handling stability and ride comfort can be improved.
