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 U-bracket which bears against the bottom of the frame member which extends longitudinally of the vehicle and is clamped thereto by bolted straps, and the lower end plate carrying a saddle plate straddling and secured to the axle member which extends transversely of the vehicle.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 226 words
An air-spring assembly for supporting a vehicle when pressurized from a pressure source said vehicle having longitudinally extending frame channel members arched over a transversely extending axle member and having leaf springs mounted transversely outwardly of the frame members and attached to the axle member outwardly of the frame members, said air spring assembly comprising pressure inflatable elastomeric bodies each oriented upright and each located directly under a frame member and directly above the axle member adjacent to a leaf spring and transversely inwardly therefrom; upper and lower end plates closing each body and respectively located near the adjacent channel member and near the axle member; upper mounting means for each upper end plate comprising an inverted U-bracket overlying the upper surface thereof and secured thereto and having a central bracket portion raised above the upper end plate and bearing against the lower surface of the adjacent channel member, and clamp means engaging opposite sides of the channel member and bolted to the raised portion of the U-bracket to secure the latter to the channel member; and lower mounting means comprising a saddle plate straddling the axle member transversely inwardly of the adjacent leaf spring and having a plate portion extending above the axle member and secured to the lower end plate of the inflatable body, and means securing the saddle plate to the axle member.
Claim 2
Dependent Claim 226 words
An air-spring assembly for supporting a vehicle when pressurized from a pressure source said vehicle having longitudinally extending frame channel members arched over a transversely extending axle member and having leaf springs mounted transversely outwardly of the frame members and attached to the axle member outwardly of the frame members, said air spring assembly comprising pressure inflatable elastomeric bodies each oriented upright and each located directly under a frame member and directly above the axle member adjacent to a leaf spring and transversely inwardly therefrom; upper and lower end plates closing each body and respectively located near the adjacent channel member and near the axle member; upper mounting means for each upper end plate comprising an inverted U-bracket overlying the upper surface thereof and secured thereto and having a central bracket portion raised above the upper end plate and bearing against the lower surface of the adjacent channel member, and clamp means engaging opposite sides of the channel member and bolted to the raised portion of the U-bracket to secure the latter to the channel member; and lower mounting means comprising a saddle plate straddling the axle member transversely inwardly of the adjacent leaf spring and having a plate portion extending above the axle member and secured to the lower end plate of the inflatable body, and means securing the saddle plate to the axle member.
Claim 3
Dependent Claim 56 words
In an air-spring assembly as set forth in claim 1, said clamp means comprising straps respectively overlying opposite legs of said channel member, each strap including a lug bolted to the raised central portion of the U-bracket, and one strap being bolted to the web of the channel member to prevent longitudinal shifting with respect thereto.
Claim 4
Dependent Claim 57 words
In an air-spring assembly as set forth in claim 1, said saddle plate comprising two downwardly-extending flange portions depending from said plate portion and shaped to snugly fit over the top of said axle, and spaced U-bolt means underlying the bottom of the axle and secured to the saddle plate near the bottoms of said flange portions.
