Problems solved by technology

The added flexibility can be achieved in a number of different ways, but the general situation is that increasing the number of parts and ball or pivot joints tends to reduce the overall stiffness and / or strength of the system
These systems are also quite expensive

Embodiment Construction

[0024] In various embodiments, the same or similar elements are provided with the same reference numerals. They need not be overly repetitive in description.

[0025] figure 1 A suspension arrangement according to the invention is shown. The device 1 comprises a slider 5 and a lower arm 6 . The slider 5 comprises an upper part 52 connected to the vehicle body 8 and a lower part 51 connected to the wheel frame 3 . The relative movement of the two parts of the slider allows the vertical suspension movement of the wheel 2 — that is to say the vertical movement of the wheel carrier 3 relative to the body 8 . The suspension system also comprises a rocker arm 4 which is connected in a camber plane on the one hand to the lower arm 6 and on the other hand to the wheel carrier 3 via a link 7 . The rocker arm 4 is also articulated to the lower part 51 of the slider in a camber plane. The figure shows zero camber (ie the wheel plane PR is the vertical plane PV perpendicular to the g...

Abstract

The invention concern in particular a suspension (1) for a wheel (2) relative to the body shell (8) of a vehicle, said device allowing a substantially vertical suspending movement and a camber movement of the wheel carrier (3) relative to the vehicle body shell, the device comprising a slide (5) and a lower arm (6), the slide including an upper portion (52) and a lower portion (51) mobile relative to each other, the upper portion being connected to the body shell and the lower portion being connected to the wheel carrier, the device further comprising a rocker (4) articulated in the camber plane to the lower arm and via a connecting rod (7) to the wheel carrier, the rocker being further articulated in the camber plane to the lower portion of the slide.

Description

technical field [0001] The present invention relates to a ground contact system of a motor vehicle, in particular to a suspension and wheel support arrangement which allows the wheel a certain degree of freedom in terms of camber relative to the suspension elements. [0002] The present invention relates more particularly to the suspension of passenger cars and sports cars. Background technique [0003] The suspension device has two main functions which must be fulfilled simultaneously at all times in operation. One of these functions is to suspend the vehicle, that is, to allow each wheel to swing approximately vertically. Another function of these devices is to guide the wheel, ie to control the angular position of the wheel plane. [0004] "Wheel plane" is the name given to the plane associated with the wheel, which is perpendicular to the axis of the wheel and passes through the center of the area of ​​static contact with the ground when the wheel is vertical. The def...
