Filed:

Dec 6, 2000

Appl. No.:

09/731673

Inventors:

Michael J. Keeler - Blacklick OH
Ashley Dudding - Plainfield IL
Jerome Cortez - Chicago IL

Assignee:

The Boler Company - Itasca IL

International Classification:

B60G 318

US Classification:

280124135

Abstract:

A suspension assembly for supporting an axle on a vehicle frame includes a pair of transversely spaced hangers mounted on and depending from the frame. Each one of a pair of longitudinally extending control arms is pivotally attached at one end of its ends to a respective one of the hangers, and at the other of its ends to a respective one of a pair of axle seats. The axle seats rigidly capture the transversely extending axle. A support member is attached to and extends longitudinally rearwardly from each of the axle seats for mounting an air spring and a shock absorber. Each of the air springs and shock absorbers extend upwardly from its respective support member and is attached to the frame. A generally rigid torque box is immovably attached at one of its ends to the frame, and at the other of its ends to the axle. The torque box is a hollow fabrication closed at each of its attachment ends by a mounting tube.

International Classification:

B60G011/26

US Classification:

280 865, 280 86751, 280124153

Abstract:

A parallelogram lift axle suspension system includes an in-line lift bellows located between and vertically aligned with a pair of upper and lower control arms so as to provide bi-directional expansion and contraction of the lift bellows for raising and lowering the suspension while increasing the space available between the longitudinal frame rails enabling use of the suspension in certain vehicles by avoiding interference with other vehicle components of the vehicle located in this space.

International Classification:

B60G 9/00

US Classification:

280124116, 280124106, 280124107, 28012411

Abstract:

A highly roll stable suspension system for a truck, trailer, or semi-trailer.

International Classification:

B60G009/02

US Classification:

280124116

Abstract:

A highly roll stable suspension system for a truck, trailer, or semi-trailer which achieves its roll stability by the use of at least three beam structures, one beam being located beneath a respective longitudinal side frame member of the vehicle, and the other being located midpoint between the side frame members and which occupies substantially less space than the space between these opposing longitudinal side frame members of the vehicle.
