Abstract
Abstract A trailing vehicle axle having telescopic piston rods connecting the steering knuckles with the pistons of pneumatic cylinders, the pistons during straight-ahead motion holding the wheels in fixed position subject to the air pressure. In a turn, one piston rod lengthens telescopically without effort and the other enters the cylinder against the air pressure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
An arrangement for stabilizing a trailing vehicle axle having, on each side of the vehicle, (a) stationary parts and (b) moving parts participating in the turning movements of the vehicle wheels, comprising a separate stabilizing element for each of the two turning directions of said axle, each said stabilizing element connecting stationary parts with moving parts and operating opposed to one another, each said stabilizing element having A. a pneumatic cylinder, B. means for supplying a fluid pressure medium to said cylinder, C. a piston disposed in said cylinder and exposed to the pressure prevailing in said cylinder, D. a piston rod affixed to said piston and formed of at least two parts in telescoping relationship with one another, said piston rod being biased outwardly by said pressure and E. abutment means on said piston rod for determining the maximum collapsed state thereof, said abutment means being individually so adjusted on each piston rod that during straight-line travel of the vehicle both piston rods are in said maximum collapsed state, whereby during a turning movement of said vehicle wheels the piston rod associated with the one turning direction undergoes free telescopic extension, while simultaneously, the piston rod associated with the other turning direction moves its associated piston into its cylinder against the pressure prevailing therein.

Claim 5
Dependent Claim
49 words
An arrangement as defined in claim 1, wherein said pneumatic cylinder includes A. a housing and B. a diaphragm secured within said housing and extending thereacross to define with a portion of said housing an expansible chamber in which said pressure prevails, said piston being affixed to said diaphragm.
Claim 6
Dependent Claim
24 words
Arrangement according to claim 1, comprising means for increasing the pressure supplied to said cylinders in response to an increased loading of said vehicle.
