DEFINITION

Classification: 280/124.11

Pivotally mounted axle or axle assembly:

(under subclass 124.1) Subject matter wherein the suspension comprises a structurally rigid bar, beam, shaft, or tube mounted for oscillatory movement upon the vehicle body, chassis, or frame about a mounting point which either (a) functions as a direct support for a single wheel carrier or spindle or (b) supports laterally opposed wheel carriers or spindles.

(1) Note. The oscillatory movement about the mounting point may be for other than suspension purposes (e.g., steering) and other than a defined axis of rotation (e.g., orbital, universal).

(2) Note. Included herein are half axles.

(3) Note. The mere mounting of an axle or axle assembly upon a horizontal axis upon the vehicle body, chassis, or frame for oscillatory movement within a vertical plane is sufficient to provide the resilient, shock absorbing support.

(4) Note. Excluded from this and the indented subclasses are an axle or axle assembly involving a pivotal interconnection between a coupling pole, perch, or reach, which interconnects front and rear running gear units so as to enable independent rocking motion thereof in a vertical plane, lacking a claimed feature providing resilient, shock absorbing support for the vehicle body, chassis, or frame (i.e., a spring). Vehicle running gear including a coupling pole, perch, or reach interconnecting front and rear running gear units provided with means enabling relative oscillatory movement of the front and rear running gear units is provided for later in the class schedule.

137.5+, for a fifth-wheel or swinging axle lacking a claimed feature providing resilient, shock absorbing support for the vehicle body, chassis, or frame, especially subclass 137.503 wherein a spherical union interconnects a coupling pole, perch, or reach to the axle or axle assembly; or subclass 137.504 wherein bracing of the coupling pole, perch, or reach interconnection to the axle or axle assembly is claimed. 141, for vehicle running gear including a coupling pole, perch, or reach interconnecting front and rear running gear units provided with means enabling relative oscillatory movement of the front and rear running gear units.
