Abstract:
1. An air spring and shock absorber unit for running gear of vehicles, the air spring and shock absorber unit comprising: an outer unit surface; one articulation point to be coupled to a frame or body of the vehicle, and another articulation point to be coupled to the running gear; a rolling bellows; a piston; a plurality of coaxial working spaces to be mutually connected by valves, at least one of said working spaces being a spring space partially bounded by said rolling bellows, and at least two others of said working spaces forming a damping space, said at least two others of said working spaces to be interconnected by flow-through throttle valves in said piston and mutually separated by said piston to be displaced in said damping space, for exchanging air as a working medium between said working spaces of at least one of said damping space or said spring space, upon the vehicle experiencing spring compression and spring extension; a substantially concentric housing disposed between said spring space and said damping space so as to be rotatable relative to the position of said articulation points; and at least one externally accessible operator control element disposed in said housing on said outer unit surface for rotation about a common axis of the air spring and shock absorber unit relative to a position of said articulation points.
