Steerable wheel axle for a motor vehicle

Device for equalizing pressure between machine housing and the

This anti-lead seal prevents the accumulation of torsional and tangential stresses on one and the same sealing element by way of an intermediate sleeve (6) which forms an axial seal gap (7) with one of the coordinated corrugated or housing-like machine parts (1, 2) and a radial seal gap (8) with the other. Since the intermediate sleeve (6) is firmly retained via a torsional safety (11) and an axial fixation (13), the sealing elements (9) for the radial seal gap (7) are stressed only by relative axial movements and the sealing elements (12) for the axial seal gap (8) are stressed only by rotational movements. Here simple elastomeric parts can be used that are easy to supply and can be quickly mounted.

A steered axle assembly comprises a relatively fixed axle beam, a pair of wheel supports pivotal on the axle beam about respective upright wheel pivot axes spaced horizontally apart on the beam transverse to a predetermined horizontal travel direction, an at least limitedly articulated track rod extending horizontally transverse to the travel direction between the wheel supports and having outer ends pivoted on same about respective upright track axes spaced in the travel direction from the respective pivot axes, and an actuator cylinder fixed to the axle beam and having a piston rod forming part of the track rod for relatively displacing the rod and axle beam horizontally transverse to the travel direction and thereby generally identically pivoting the wheel supports about the respective wheel pivot axes. Respective rod and beam abutment formations fixed on the track rod and relative to the axle beam confront each other horizontally transverse to the travel direction. A stop or spacer fixed to one of the formations is engageable horizontally perpendicular to the travel direction with the other formation for limiting pivoting of the wheel supports in one direction relative to the beam beyond an end position with the spacer engaging the other formation.
