Abstract

PURPOSE:To reduce the offset and the inclination angle of the king pin, by pivoting a strut at the intermediate portion of a suspension lower arm coupled with a knuckle while providing a member slidable on the strut on said knuckle. CONSTITUTION:The inner end of the suspension lower arm 2 is fixed rotatably to the chassis 1 around the center of rotation or the fixing hole 3 while the outer end of the suspension lower arm 2 is ball jointed to the lower section of the knuckle 5. The upper section of the piston rod 6a of the strut 6 is fixed through the upper mount 7 to the chassis 1, while the lower section of the strut 6 is pivoted to the pivot section 2a at the intermediate section of the suspension lower arm 2. Furthermore a member for sliding up and down on the cylinder 6b is fitted over the outer circumference of the cylinder 6b of the strut 6 where the sliding member 8 is ball jointed through the extension to the upper section of the knuckle 5.

Next, to explain the operation of the above embodiment □, - When the wheel 4 moves upward from the intended state as in the case of a bump, the suspension lower arm 2 rotates through the mounting hole 3 at its inner end. As the center of movement rotates counterclockwise in the figure, the strut 6 is compressed by the pressing force from the suspension lower arm 2, and the cylinder 6b of the strut 6 moves upward, and the sliding member 8 , the wheel 4 is allowed to move upward by sliding upward on the sill 6b of the strut 6 by the difference in upward displacement between the pivot joint 2a and the outer end, that is, the knuckle 5, as the suspension lower arm 2 rotates.

On the other hand, when the direction of rotation of the wheel 4 changes as during cornering, the knuckle 5 moves between the center PX of the ball joint with the sliding member 8 at the top and the ball between the suspension lower arm 2 at the bottom. By rotating around the straight line connecting the center P2 of the joint portion, that is, the kingpin axis 11, the rotation direction of the wheel 4 can be changed.

In that case, the kingpin axis /1 is close to the center line j2 of left-right symmetry of the wheel 4, and the kingpin axis /1 on the center line 13 of rotation of the wheel 4 is the center line j2 of left-right symmetry.
2, that is, the mass offset C, is relatively short, so the kingpin inclination angle (kingpin axis 1.
Even if the inclination angle with respect to the vertical line j4) b is not increased,
The kingpin offset (distance between the kingpin axis 1 on the road surface g and the center line 11 of left-right symmetry of the wheels 4) a can be reduced to a value close to almost zero. In this way, it is possible to reduce both the king pin offset C and the king pin inclination angle, and as a result, it is possible to suppress the occurrence of the shimmy phenomenon, the kickback phenomenon, etc.
