International Classification:

B60G003/12

US Classification:

280124128, 28012413, 280124149

Abstract:

A non-torque reactive air suspension exhibiting excellent roll stability characteristics is shown to include frame hangers mounted to frame rails extending longitudinally on opposite sides of a vehicle. Longitudinally extending beams are connected to the frame hangers at one end and extend parallel to the frame rails. At their other ends, the beams are joined by a crossbrace extending laterally across the vehicle centerline. In a central portion thereof, the beams have an axle pivot bore to which an axle clamp assembly is connected, the axle clamp assembly clamping a drive axle housing for the vehicle. The axle pivot bore is generally aligned with the drive axle. A control rod assembly is connected to suspension or frame components. Together with the beams, the control rod assembly forms a parallelogram configuration wherein the beams form the lower linkages of that configuration and the control rods included within the control rod assembly form the upper linkages of that configuration.

International Classification:

B60G 9/00

US Classification:

280124116

Abstract:

A leading or trailing arm vehicle suspension system comprised of a fabricated vehicle axle and an arm assembly. The arm assembly includes an axle bracket attached to the axle and a leading or trailing arm attached to the axle bracket. The arm provides bending stiffness to control axle windup and longitudinal stiffness to control axle position is disclosed. The axle bracket is attached to the vehicle axle with a through-bolt connection. The axle bracket or the arm includes rack and pinion mounting attachment holes and also includes other built-in features providing efficient transfer of loads into the vehicle axle.

US Classification:

280124175

Abstract:

A vehicle leaf spring suspension having a low spring rate is disclosed. The suspension has an axle seat secured to a vehicle axle. The leaf spring is clamped at its spring seat area to the axle seat at the clamp group mounting surface of the axle seat and with certain of the disclosed axle seats, can be clamped such that the spring seat area is asymmetrically positioned with respect to the vehicle axle centerline. Also, an active clamp group arrangement can be used to utilize the entire physical length of the leaf spring.

International Classification:

B60G 11/04

US Classification:

280124175

Abstract:

Axle seats are disclosed for incorporation into vehicle suspensions of the type having a laterally extending axle and a longitudinally extending leaf spring. The axle seat includes a seat portion, a clamp group mounting surface, and an air spring mounting flange. A sidewall of the axle seat connects the seat portion to the clamp group mounting surface and the air spring mounting flange. The clamp group mounting surface and air spring mounting flange are configured to be positioned at different heights when the seat portion is connected to an axle. A second sidewall and air spring mounting flange may be provided, in which case the air spring mounting flanges may be spaced apart to provide an area through which a leaf spring may extend.
