  • Patent number: 8046893
    Abstract: A method for assembling a motor vehicle axle including suspension arms and a cross-member mounted between the arms. The method applys an adhesive element on at least one portion of the cross-member, mounts the portion inside a bore of one of the suspension arms to as to leave a clearance between the suspension arm and the adhesive element, and radially deforms one of the assembling elements of the cross-member and the suspension arm to obtain a contact between the adhesive element and the bore of the suspension arm.
    Type: Grant

  • Patent number: 7959057
    Abstract: A tool for assembling a part made of a ferromagnetic material with a part made of a paramagnetic material. The tool includes a first tool part including a first abutment and a first electromagnetic coil. The tool also includes a second part including a second abutment, wherein the second part is mechanically assembled with the first part such that the first and second abutments are selectively attracted or repelled with respect to each other. The first electromagnetic coil is used for generating an electromagnetic flux that enables the paramagnetic part to be pushed towards the second abutment and/or the ferromagnetic part to be attracted thereto when the first and/or second part is placed between the first and second abutments.

  • Patent number: 7871092
    Abstract: A motor vehicle axle system including two longitudinal arms made of molded material and a torsionally flexible cross bracing made of high strength material different from the material of the arms, each arm including a lug for assembling by structural bonding the cross bracing to the arms. Each lug has an assembling edge configured to be assembled to one end of the cross bracing by generating self-binding with a surface of the cross bracing, an adhesive layer being applied between the assembling edge and the surface of the cross bracing, and the assembling edge of each lug has a variable thickness along its periphery and in the direction of the lug axis, the thickness being selected so as to minimize stresses exerted on the adhesive in the assembling zone. A method assembles the motor vehicle axle system.

  • Patent number: 6011246
    Abstract: An induction heating device for surface treating the teeth (11) of a mechanical part on which each tooth (111) has a projecting tip (111s) and a tooth root linking the tooth to an adjacent tooth, wherein an in duction coil (12, 12') is spaced from the tooth tips and powered by at least one high-frequency current source. The coil consists of a set of conductive segments (24, 24') individually orthogonal to the generatrix (d, d') of the teeth, located above respective tooth tips and interconnected via connecting segments (25, 25').
