Embodiment Construction

[0034] Hereinafter, a preferred embodiment of the present invention will be described based on the drawings.

[0035] Reference Figure 1 ~ Figure 3 , The suspension device 10 is a multi-link suspension, and includes: a link unit 16 that connects the steering knuckle 14 to the subframe 12 of the vehicle body 11; and a buffer device (shock absorber) that connects the steering knuckle 14 and the vehicle body 11 18.

[0036] The front and rear attachment portions 42, 43 of the subframe 12 are attached to the rear frame (body) by bolts.

[0037] The knuckle 14 includes a knuckle body 21. This knuckle main body 21 has an opening 22 formed substantially in the center thereof. A front upper connecting portion 23 and a rear upper connecting portion 24 are provided on the upper part of the knuckle main body 21. A front lower connecting portion 25 and a rear lower connecting portion 2 are provided at the lower part of the knuckle main body 21. A central connecting portion 27 is provided in...

Abstract

A suspension device in which a knuckle for supporting a wheel is supported by arms and a damper is connected to the knuckle. A suspension device (10) is configured in such a manner that the intersection (73) between a line extended from an elastic kingpin axis (68) of a rear wheel (31) and a road surface (72) is located on the rear side, relative to the vehicle, of the ground contact center (74) of the rear wheel. The elastic kingpin axis is tilted forward relative to the vehicle and is disposed below the rotation center (32) of the rear wheel in the vertical direction. A lower connection section (81b) of a damper (18) is provided on a line (33) drawn in substantially the vertical direction from the rotation center of the rear wheel. A damper axis (84) is tilted inward in the width direction of the vehicle and tilted forward relative to the vehicle.

Description

Technical field [0001] The present invention relates to a suspension device which uses a plurality of arms to support a steering knuckle, and a buffer device is connected to the steering knuckle, and the steering knuckle is used to support wheels. Background technique [0002] There is a suspension device such that the reaction force acting on the shock absorber (hereinafter referred to as "shock absorber reaction force") or the lateral force acting on the wheel (force in the vehicle width direction) becomes the wheel's A multi-link suspension in which the shock absorber and multiple arms are arranged by the force in the toe direction. [0003] Specifically, in order to make the shock absorber reaction force the force in the toe direction of the wheel, the layout of the plurality of arms is set so that the shock absorber reaction force acts on the elastic kingpin shaft along the rear of the vehicle. [0004] In addition, in order to make the lateral force (force in the vehicle width...
