Abstract: A compressed air generation apparatus for an air spring arrangement having an air spring and a passive compressed air generator. The compressed air generator converts relative displacements of its two portions in at least one direction into generation of compressed air. The first portion is coupled to a first connection point for connection to a first spring portion of the air spring of the air spring arrangement. The second portion is coupled via a linkage to a second connection point to a second spring portion of the air spring of the air spring arrangement. Translational relative movements between the connection points cause the relative displacement of the two portions with respect to one another. The linkage converts an adjusting movement introduced into the second connection point with an adjusting force into a higher actuation force and a lower actuation movement at the second portion of the compressed air generator.

Abstract: A cab mount (25) for a vehicle (1) has a cab (5) separate from a vehicle frame (3). The cab is mounted so as to be levelable with respect to a vehicle standing surface by means of at least three adjustable actuators (7-13), and a levelness adjusted by the actuators is blockable at least when the vehicle is stationary. The cab mount has at least one stabilizer (27) for supporting roll movements of the cab during driving operation. The stabilizer has at least two switching steps with different spring rates, and the stabilizer has the higher of the at least two spring rates in stationary operation of the vehicle when the cab is leveled.
