DEFINITION

Classification: 280/124.157

Fluidic suspension:

(under subclass 124.1) Subject matter wherein the suspension includes a displaceable, flowable agent.

(1) Note. A suspension arrangement including a regulatable elastic means, including a fluid suspension arrangement, responsive while the vehicle is in surface traversing motion is provided for earlier in the class schedule. Similarly, a fluid suspension arrangement for vertically predisposing a load, load carrier, or receptacle portion is provided for earlier in the class schedule.

(2) Note. This subclass is the residual subclass for a fluid suspension not classifiable elsewhere or in an indented subclass.

(3) Note. In accordance with accepted industry and mechanical engineering convention, a shock absorber, per se, is not deemed to be a fluid suspension element for the purposes of this subclass and the indented subclasses since it normally does not support any weight but merely retards the extent of motion provided by a supporting spring device attempting to distort or return to its undeflected condition.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.5+, for an active suspension including a regulatable elastic means responsive while the vehicle is in surface traversing motion.

6.15+, for a vehicle including means used to alter the relative height or levelness of the vehicle body, chassis, or frame which may or may not include a fluidic suspension element.

86.5, for an auxiliary axle assembly which may or may not include a fluidic suspension. 86.75+, for vehicle running gear including static alignment adjustment means which may or may not include a fluidic

suspension element.

104+, for vehicle running gear including an equalized frame, especially subclasses 678 or 683 for tandem axles including fluid spring means.

124.101+, for a suspension arrangement including means for presetting an elasticity parameter.

124.103, for a suspension arrangement intended to sideways or transversely incline the vehicle body, chassis, or frame toward a center of curvature about which the vehicle body, chassis, or frame is executing arcuate travel which may or may not include a fluidic suspension element. See the (2) Note supra.

124.104+, for a suspension arrangement intended to restrict front-to-rear or fore-and-aft inclination of the vehicle body, chassis, or frame which may or may not include a fluidic suspension element. See the (2) Note supra.

124.106+, for a suspension arrangement intended to restrict sideways or transverse tilt of the vehicle body, chassis, or frame which may or may not include a fluidic suspension element. See the (2) Note supra.

124.112, for a suspension arrangement including a rocking axle having a fluid actuator. See the (2) Note supra.

124.116, for a suspension arrangement wherein an axle or axle assembly is mounted upon a horizontal and transverse pivot axis which may or may not include a fluidic suspension element. See the (2) Note supra.

124.117+, for a steerable or steered swivel truck which may or may not involve a fluidic suspension element. See the (2) Note supra.

124.125+, for a suspension arrangement separately supporting an individual wheel for interconnecting a stub axle to the vehicle body, chassis, or frame which may or may not include a fluidic suspension element. See the (2) Note supra.

200+, for running gear of a general utility occupant-propelled-type wheeled land vehicle, especially subclasses 274+ or 283+, which may or may not include a fluidic suspension element. Additionally, in accordance with the (2) Note of subclass 200, motorcycle frames and running gear, without features causing classification in Class 180, Motor Vehicles, are included in these subclasses. See the (2) Note supra. 400+, for an articulated vehicle or plural interconnected vehicles (i.e., vehicle train) which may or may not include a fluidic suspension element. See the (2) Note supra.

781+, for a vehicle running gear including specific frame

construction, especially subclass 782 wherein the specific frame construction forms a fluid conduit which may or may not be a suspension fluid. See the (2) Note supra.

188, Brakes,

266.1+, for a retarding or stopping mechanism employing the reluctance of a medium to be disturbed. This class (Class 188) includes a shock absorber, per se.

267, Spring Devices,

2+, for vehicle spring devices, per se, especially subclasses 64.11+ for fluid spring devices or subclasses 217+ for a mechanical spring device and a fluid retarder (i.e., shock absorber). Class 267 provides the locus for the combination of a spring device and a shock absorber.
