Abstract
The invention provides a hydropneumatic suspension system which is particularly suitable for lorry cabs of the kind which require to be tilted about a horizontal axis for access to the engine. Such a system normally has the disadvantage that a hydropneumatic unit, incorporating a diaphragm does not provide a firm pivot anchorage for the cab tilting system. The invention overcomes this problem by pivotally attaching one portion of the displacer unit, below the diaphragm, to a downwardly extending formation of the cab and arranging for abutment between the formation and the displacer unit portion above the tilt axis to maintain the displacer unit portions in alignment when the cab is in the ride position.
