Abstract

Abstract An air-spring assembly for mounting in a vehicle as a part of the vehicle suspension and including a pressure-inflatable elastomeric body having rigid end plates by which it is mounted between a chassis member and an axle member of the vehicle, the upper end plate carrying an inverted L-shaped bracket which is secured to the side of a frame member which extends longitudinally of the vehicle, and the lower end plate carrying an inverted U-bracket secured to the U-bolt and clamping plate assembly of the leaf spring mounted on the axle member of the vehicle.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 239 words
An air-spring assembly for mounting on a longitudinal frame member of a vehicle to support the latter with respect to an axle member extending transversely of the vehicle when pressurized from a pressure source, the vehicle having a leaf spring disposed parallel to the frame member and transversely offset therefrom and the axle member being attached to the leaf spring by U-bolts extending around the axle member on each side of the leaf spring and having their ends extending up through a clamping plate disposed across the top of the leaf spring, said air-spring assembly comprising a pressure inflatable elastomeric body oriented upright adjacent to the frame member and having upper and lower end plates closing the body and respectively locatEd near the top of the frame member and near the axle member; upper mounting means comprising an L-shaped bracket having a verticle and a horizontal leg with diagonal reinforcing means extending between and secured to them, the vertical leg being fastened to the frame member with the horizontal leg extending from a level near the top of the frame member and overlying said upper end plate and being bolted thereto; and lower mounting means comprising an inverted U-bracket having a raised central portion bolted to said lower end plate and having downwardly extending flanges carrying feet with mounting holes receiving the upper ends of said U-bolts, and the U-bracket being secured by nuts superimposed upon said clamping plate.
Claim 2
Dependent Claim 239 words
An air-spring assembly for mounting on a longitudinal frame member of a vehicle to support the latter with respect to an axle member extending transversely of the vehicle when pressurized from a pressure source, the vehicle having a leaf spring disposed parallel to the frame member and transversely offset therefrom and the axle member being attached to the leaf spring by U-bolts extending around the axle member on each side of the leaf spring and having their ends extending up through a clamping plate disposed across the top of the leaf spring, said air-spring assembly comprising a pressure inflatable elastomeric body oriented upright adjacent to the frame member and having upper and lower end plates closing the body and respectively locatEd near the top of the frame member and near the axle member; upper mounting means comprising an L-shaped bracket having a verticle and a horizontal leg with diagonal reinforcing means extending between and secured to them, the vertical leg being fastened to the frame member with the horizontal leg extending from a level near the top of the frame member and overlying said upper end plate and being bolted thereto; and lower mounting means comprising an inverted U-bracket having a raised central portion bolted to said lower end plate and having downwardly extending flanges carrying feet with mounting holes receiving the upper ends of said U-bolts, and the U-bracket being secured by nuts superimposed upon said clamping plate.
Claim 3
Dependent Claim 100 words
In an assembly as set forth in claim 1, the L-shaped bracket having its verticle leg of one width as measured longitudinally of said frame member and having its horizontal leg enlarge outwardly from the vehicle leg to a greater width as measured in the same direction, and said diagonal reinforcing means comprising two diagonal members respectively fixed at their lower ends near opposite lower corners of said vertical leg and fixed at their upper ends near opposite outer ends of said horizontal leg, whereby the diagonal members diverge away from each other as measured longitudinally of said frame member.
