Problems solved by technology

However the central part limits the rigidity of the arm and also substantially reduces the different articulation fixations with which this arm is articulated
In addition, the positioning of the two shells when fixed is unreliable

Embodiment Construction

[0034] figure 1 is a perspective view of an axle 2 of a motor vehicle comprising a suspension arm 4 according to the invention. Each of said suspension arms is articulated mounted to the vehicle structure 6 , in this case to the engine mounts, and to the wheel supports 8 of the vehicle.

[0035] figure 2 is a perspective view of a suspension arm 4 according to the invention. The articulation is in this case assembled on the suspension arm. An elastically deformable transverse articulation can be seen at the first end 10 , the axis of which is oriented substantially vertically when the arm is fitted on a vehicle. The assembled ball and socket joint can also be seen at the second end 12 of the arm. A third articulation is also visible at an intermediate position 13 between the two ends of the arm and whose axis is oriented in the longitudinal direction when the arm is fitted on a vehicle. The arm comprises two half-shells 14 and 16 which are fixed to each other and togethe...

Abstract

The invention relates to a motor vehicle suspension arm (4) including two shell halves (14, 16) attached to one another along a median joining plane (L) and forming the structure of the arm (4); the two shell halves (14, 16) include first attachment edges (18, 20) extending in the median joining plane (L) and in mutual contact in said plane, and second attachment edges (22, 24) extending transversely, preferably perpendicularly, to said plane (L), said second attachment edges being in mutual contact in the transverse area thereof. The invention also relates to a motor vehicle including such a suspension arm (4), the arm being hingedly mounted to the structure of the vehicle and to a wheel of said vehicle.

Description

technical field [0001] The invention relates to the field of motor vehicles. More specifically, the invention relates to the field of coupling arms of vehicles, and more particularly the field of implementation of suspension arms of motor vehicles. Background technique [0002] Motor vehicles typically include shock absorbers that are substantially vertically oriented and serve to dampen vibrations of the suspension. The suspension comprises arms for ensuring an articulated coupling between the vehicle structure and the wheels. Such articulated suspension arms are generally oriented laterally and include articulations to follow the vertical movement of the wheel. Such suspension arms are particularly stiff for resisting the constraints associated with driving the vehicle, especially when braking, accelerating and steering. Good road grip of the vehicle also requires the strength of this suspension arm combined with a small mass. A lower mass is particularly advantageous ...
