Embodiment Construction

[0040] [40] Referring first to Figure 1, Figure 1 shows a semi-rigid (also referred to as "deformable") axle used in the rear of a vehicle, comprising a beam 1 mounted on two substantially symmetrical on arms 2 and 3. At the end of each arm 2, 3, a plate 6 is arranged at one end, mainly for receiving a wheel axle, and at the other end, a recess 7, mainly for receiving an elastic hinge connecting the body. As shown in FIG. 1, the beam 10 has a non-circular and non-constant cross-section in order to have sufficient bending rigidity and torsional flexibility to withstand the forces in operation.

[0041] [41] The following describes the assembly of an arm at one end of the beam, this method is also applicable to the assembly of the two arms 2 and 3 at both ends of the beam 10.

[0042] [42] However, such assemblies are generally complex in design and production, especially when the materials used are not weldable between them (beam and arm). Typically, the beam may be steel whi...

Abstract

The invention relates to semi-rigid axles and, in particular, to a method for assembling the arms (2) of one such axle to the crosspiece thereof (1) by magneto-forming. In this way, the relative positions of the arms and the crosspiece can be adjusted and fixed in said positions in a single step.

Description

technical field [0001] [01] The present invention relates to the fixing of beams and arms on axles, in particular semi-rigid axles of touring cars. Background technique [0002] [02] This axle consists of two longitudinal arms, each of which is connected on the one hand to the wheel and on the other hand to the body. Each arm is fastened to the end of a cross member extending across the width of the vehicle, which is stiffer in bending and softer in torsion. Usually, this fastening takes place by bolting or welding (usually by means of an insert when the arm is of a material that is not readily weldable) after adjusting the respective positions of the arm and cross member with the highest possible precision. [0003] [03] Such shafts are generally known for their lightness, economy, and quick assembly. [0004] [04] However, the above-mentioned known fixing methods increase the weight and complicate the manufacturing method, and even after fixing, the durability conditions...
