Abstract
Motor vehicle axle assembly that includes two arms configured to be mounted in an articulated manner to a motor vehicle body. Each of the two arms is coupled to a wheel-bearing knuckle. A crosspiece is coupled to each of the two arms. At least one insert includes at least one elastomer element and at least one bearing. The at least one insert is arranged to at least one of couple at least one end of the cross piece to at least one of the two arms and couple a first part of the cross piece to a second part of the cross piece. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
Claims11
Axle, comprising two arms (4A, 4B) intended to be mounted articulatedly on the body and each equipped with a wheel-bearing knuckle (5A, 5B), as well as a crosspiece (3) which connects these two arms and is equipped with at least one insert (2) comprising an elastomer element (21), which is positioned, shaped and adapted to effect in part at least a torsional torque in reaction to the oscillations of one arm relative to the other, characterised in that the insert further comprises a bearing (22) intended to maintain in cooperation with the elastomer element substantially one angular position of each of the two arms relative to the crosspiece, whilst permitting rotation due to the oscillation of the arms, to which rotation the elastomer element (21) reacts torsionally.
Axle according to one of the preceding claims, characterised in that the bearings (22) are located at a selected distance from the elastomer element (21).
Axle according to one of the preceding claims, characterised in that a first insert (2A) comprising an elastomer element and a bearing is mounted between the crosspiece (3) and one of the arms (4A), whereas a second insert (2B), also comprising an elastomer element and a bearing, is mounted between the crosspiece and the other arm (4B).
Integral insert for an axle according to one of the preceding claims, comprising an elastomer element (21) and a bearing (22), as well as means (23, 24) of keeping the elastomer element (21) and the bearing (22) substantially coaxial and located at a selected distance from one another.
