摘要:
The invention concerns a motor vehicle flexible axle comprising two longitudinal arms (20) connected by a cross bracing (10) with open cross-section whereof the flanks (11), (21) have each an edge (1), (2) extending between docking zones (4) with the ends of said cross bracing. The invention is characterized in that said edges (1), (2) have a non-rectilinear shape enhancing their tensioning when said cross member is subjected to torsion, said tensioning enabling said docking zones (4) to be relieved of stresses due to said torsion.

The invention relates to a connecting element which is disposed between an anti-roll bar (51) and a longitudinal arm (52) of a motor vehicle axle, comprising a coupling surface (3) having a segment (2) for coupling with the anti-roll bar (51), said surface (3) connecting two lateral lugs (1) which are intended to be solidly connected to the longitudinal arm (52). The invention is characterised in that: (i) each of the lugs (1) comprises a first transverse section which, depending on the thickness thereof, extends essentially between two planes having a first spacing therebetween; and (ii) the aforementioned coupling surface (3) comprises, at least partially, a second transverse section which, depending on the thickness thereof, extends between two planes, one of which contains the above-mentioned coupling segment (2), with a second spacing therebetween which is greater than the first.

The invention relates to a method of producing a sheet metal part comprising at least one base surface (112) having a boss (111) close to at least one of the edges thereof, known as the proximal edge (131), said boss (111) being provided on the inner face (1121) of the base surface (112). The invention is characterised in that it comprises: at least one drawing step, during which the boss (111) is produced; and at least one bending step, during which the proximal edge (131) is bent in the direction of the boss (111) until it extends essentially parallel to the aforementioned inner surface (1121), said bending step consisting in exerting a counter force against the face of the base surface (112) opposite the inner face (1121) at least close to the proximal edge (131).

The invention relates to a method of producing a braking element (1) which is intended to be fixed to the hub (3) and to receive a wheel (2), said braking element (1) having at least one hole (16) for the passage of fixing means (20) which are intended to clamp the braking element (1) between the wheel (2) and the hub (3). The invention is characterised in that it comprises a braking element (1) moulding step in which the aforementioned hole(s) (16) is produced, thereby ensuring that any possible burrs occur in areas of the element away from the hole(s) (16).

摘要:
The invention relates to a piece of equipment for the production of a closed-section cross-member which is intended to connect two longitudinal arms of a flexible axle of a motor vehicle. The inventive equipment comprises at least one matrix (3) which is intended to co-operate with a punch (2) in order to form a torsion area (L) of a certain length on the closed section of the cross-member and means for maintaining the cross-member in position. The invention is characterised in that the length of the matrix (3) and/or the punch (2) can be adapted in order to adapt the length of the torsion area (L).
