An embodiment will be shown in which the present invention is applied to a parallel link type strut type suspension that supports the rear wheels of a front-drive vehicle. In the figure, reference numeral 1 denotes a strut, which is composed of a cylindrical strut body 2 and a shock absorber 3 built into the body 2. The upper end of the piston rod 4 of the shock absorber 3 is
It is attached to the vehicle body 6 so as to be able to swing slightly via a mounting device 7 fixed to the vehicle body 6 with bolts 5. A coil spring 8 is compressed and interposed between an upper seat 9 on the side of the vehicle body 6 and a lower seat 10 fixed to the strut body 2, and has the function of supporting the weight of the vehicle. 11 is a bumper rubber.
The lower end of the strut 1 is fixed to a bracket 30 by means such as welding, and the bracket 30 is fixed to the wheel support member 12 with bolts 13a and 13b. Reference numeral 31 indicates a cam-type camber angle adjustment mechanism, which has a pair of arc-shaped elongated holes 30a in the bracket 30 centered around the lower bolt 13b, and
A pair of guide members 32a, 32b fixed at 0,
A pair of eccentric cam disks 33a, 33b that engage with the guide members 32a, 32b, respectively, and a bolt 1 that is inserted into the wheel support member 12 and tightens them.
3a, an eccentric cam disk 33a,
By appropriately rotating 33b, the wheel support member 12 can be tilted together with the upper bolt 13a about the lower bolt 13b, thereby adjusting the camber angle.
The wheel support member 12 rotatably supports a wheel 14 on its spindle 12a, and is supported by the vehicle body 6 by a lower control link 15 connected in the vehicle width direction and a radius link 16 connected in the longitudinal direction of the vehicle body 6. As shown in FIG. 2, the lower control link 15 has a parallel link type in which a front link 15a and a rear link 15b are arranged in parallel. The front link 15a and the rear link 15b have their outer ends located on both front and rear sides of the wheel support member 12, and are connected to the bushes 17 and 15, respectively.
18 is interposed and is swingably supported on the wheel support member 12 by a bolt and nut 19, and the inner end thereof is supported by bolts and nuts 22 and 23 with bushes 20 and 21, respectively, to the vehicle body. It is pivotably supported at 6. 24 is a cam type toe angle adjustment mechanism.

As shown in FIG. 4, the radius link 16 is similar to the conventional radius link 1 shown in phantom lines.
6', its ends are bent inward, and the spacing is narrower than the spacing between the collars 12b of the wheel support members 12 provided on both sides in the vehicle width direction. Such a radius link 16 has its end portion elastically expanded, and a bush 25 is interposed therebetween, so that the radius link 16 extends downward from the pivot point O (see FIG. 1) of the lower control link 15 of the wheel support member 12. It is attached to the located collar 12b by tightening a nut 26, and is attached to the vehicle body 6 with a bracket 28 with bushes 27 interposed on both sides of the center portion. Therefore, the radius link 16 is connected to the wheel support member 12.
and the vehicle body 6 in the longitudinal direction, and the vehicle body 6
It acts as a stabilizer to suppress the roll.

The radius link 16 is supported by the wheel support member 12 below the pivot point O of the lower control link 15, that is, the front link 15a and the rear link 15b, and has an elastic repulsive force F2 that urges the wheel support member 12 inward. Therefore, the mount device 7 on the upper part of the strut 1 receives a reaction force F1 that acts inward in the vehicle width direction, which is opposite to a reaction force F1 that acts outward in the vehicle width direction, which is generated due to the structure of the strut type suspension. 3 and generates a bending moment M 2 in the strut 1. Therefore, this reaction force F 3 that acts inward in the vehicle width direction
is opposed to the reaction force F 1 to the outside in the vehicle width direction,
The bending moment of the actual strut 1 (M 1
M2 ) In turn, the amount of bending deformation is reduced. As a result, the friction of each sliding portion of the piston 106 and rod guide 108 shown in FIG. 6 can be reduced.

Note that the wheel support member 12 of the radius link 16
In the case of a strut-type suspension in which the support for the lower control link 15 is located above the pivot point O of the lower control link 15, the radius link 16 is manufactured with its ends widened, and the distance between the ends is adjusted elastically. By reducing the size and attaching it to the wheel support member 12,
A reaction force F3 acting inward in the vehicle width direction can be applied to the upper part of the strut 1, and the same effect as in the above embodiment can be obtained.

(Effects of the Invention) As understood from the above description, according to the present invention, the amount of bending deformation of the strut is reduced by using the elastic repulsive force of the radius link to cancel out the bending moment acting on the strut. Since the sliding friction of the strut is reduced without increasing the number of structural members of the strut type suspension, it is possible to obtain the effect that the ride comfort of the vehicle can be improved with a simple structure.
