Abstract
Abstract An air spring axle assembly for spring suspension and sway restraining of vehicle chassis, including a U-shaped frame spring-mounted in relation to the chassis and supporting a stiff wheel axle. The U-shaped frame is torsion-proof and constructed as a box girder, the air springs of the assembly resting in the vicinity of the web of the girder, the wheel axle unit with the wheels being tightly fixed to said frame as a unit, and the U-girder being also mounted in the chassis in chassis shackles by means of a draw link mounted for each leg in the U-girder. The opposite or free end of the link is linked to the corresponding leg of the U-girder at a point between the chassis shackles and the web and the ends of the legs remote from the web are inserted in the chassis shackles and held in the latter by sway controlling units combined with the mounting bushings of the shackles and enabling a swinging movement, guided laterally through the mountings, of the wheel axle in a vertical direction.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
A sway-restraining air spring axle assembly for a vehicle chassis comprising in combination: a U-shaped girder member including a pair of laterally spaced parallel legs and a web portion connected therebetween adjacent the rear end of said legs; an air suspension spring supported on each of said legs adjacent said web; means for connecting said air suspension spring to said girder member and to said chassis; a pair of first laterally spaced shackles connected to and depending from the chassis and adapted to respectively receive therein the front end portions of said girder legs; a pair of second laterally spaced shackles connected to and depending from the respective legs of said girder member intermediate said web and front end portions of the legs; a pair of laterally spaced draw links mounted pivotally respectively in said first and second shackles; means for resiliently securing the front end portions of said girder legs to said draw links within said first shackles and for adjustably controlling such resiliency; a rigid wheel axle assembly connected rigidly to said girder member.
Claim 2
Dependent Claim
176 words
A sway-restraining air spring axle assembly for a vehicle chassis comprising in combination: a U-shaped girder member including a pair of laterally spaced parallel legs and a web portion connected therebetween adjacent the rear end of said legs; an air suspension spring supported on each of said legs adjacent said web; means for connecting said air suspension spring to said girder member and to said chassis; a pair of first laterally spaced shackles connected to and depending from the chassis and adapted to respectively receive therein the front end portions of said girder legs; a pair of second laterally spaced shackles connected to and depending from the respective legs of said girder member intermediate said web and front end portions of the legs; a pair of laterally spaced draw links mounted pivotally respectively in said first and second shackles; means for resiliently securing the front end portions of said girder legs to said draw links within said first shackles and for adjustably controlling such resiliency; a rigid wheel axle assembly connected rigidly to said girder member.
Claim 3
Dependent Claim
50 words
An axle assembly according to claim 1, wherein said pair of girder-connected shackles each comprise a web and a pair of depending laterally spaced legs, said draw links being mounted respectively in said chassis-connected and girder-connected shackles so as to extend substantially parallel to and below the overlying girder leg.
Claim 4
Dependent Claim
65 words
An axle assembly according to claim 1, wherein the front end portion of each of said girder legs is inclined upwardly and is positioned within the associated chassis-connected shackle, said upwardly inclined girder leg portions being disposed along a line which coincides with a projected line extending through the axis of the axle and the pivotal axis of the draw link in the girder-connected shackle.
Claim 5
Dependent Claim
74 words
An axle assembly according to claim 1, wherein said means for resiliently securing said girder legs and draw links each include clamping means comprising an upwardly extending stirrup connected to said draw link, at least one resilient element positioned between the upper portion of said stirrup and said girder leg and above said girder leg, and fastening means for adjustably tightening the thus formed resilient connection between said girder leg and said draw link.
Claim 6
Dependent Claim
28 words
An axle assembly according to claim 1, wherein each of said girder legs is a channel member and said web portion of the girder is a box girder.
Claim 7
Dependent Claim
49 words
An axle assembly according to claim 1, wherein said means for connecting said air suspension spring to said girder and chassis include end plates on said air suspension spring, girder and chassis adapted to coact to slidably and detachably connect said air suspension spring to said girder and chassis.
