Embodiment Construction

[0063] In general, refer to figure 1 and figure 2 , the overall triangular suspension according to the invention comprises a link arm equipped with two second joints not only as shown in these figures along axes perpendicular to each other (horizontal and vertical respectively) The orientation may also be oriented in any other direction depending on the configuration of the first unsuspended mass (eg wheel train) involved and its connection to the second suspended mass (eg chassis).

[0064] as from figure 1 and figure 2 It can be seen that the link arm 1, 1' for a motor vehicle suspension according to the invention essentially comprises a hardened part 2 or shell formed from two identical half shells 2a and 2b, which are to be These two identical half-shells are superimposed and are obtained by inserting buckling-resistant webs 3 along the median longitudinal plane of the shell 2 . Each half-shell 2a, 2b is made of a thermoplastic or thermosetting matrix composite mater...

Abstract

The present invention relates to a linking arm for connecting a first unsprung mass to a second sprung mass, and to the method for manufacturing same. The invention applies in particular to a suspension for a motor vehicle, said arm being capable of being provided on a wheel suspension, including triangular recesses for receiving a ball joint for linking to a spindle of the wheel and two hinges for linking to the chassis of the vehicle. Said arm (1) comprises recesses {14, 15, 16} for receiving a first hinge (14a) for linking to the first mass and at least one second hinge (15, 16) for linkingto the second mass, and includes: a rigidifying portion (2) made of a first composite material with thermoplastic or thermosetting matrix reinforced by fibres and which comprises a peripheral edge (8) of the arm; and an anti-buckling portion (3) inserted into the rigidifying portion and extending from the edge over substantially the entire arm. According to the invention, the fibres are continuous and collected in the form of a main hank of first fibres extending along the edge, which encloses the anti-buckling portion.

Description

technical field [0001] The present invention relates to a link arm suitable for connecting together two structures or masses under force and a method of making the arm. The invention applies in particular to a suspension system of a front or rear wheel train of a motor vehicle, comprising in particular a housing in the wheel suspension, which on the one hand receives a coupling joint coupled to a stub axle and on the other An aspect receives at least one coupling joint, for example coupled to a chassis of a vehicle. Background technique [0002] In a known manner, the suspension system of a motor vehicle comprises a suspension arm comprising a ball joint at a minor axis and two articulation joints coupled to the chassis of the vehicle, wherein these three joints together form the The arms are triangular in overall triangular shape. These linkage arms are generally metal and therefore relatively heavy. [0003] In recent years, efforts have been made to lighten such metal ...
