DEFINITION

Classification: 180/337

TRANSMISSION MECHANISM:

(under the class definition) Mechanism connecting the power shaft to the road wheels and claimed in combination with specific vehicle structure.

(1) Note. Classes 56, Harvesters; 111, Planting; and 172, Earth Working, subclasses 105+, contain some agricultural vehicles carrying transmission mechanism connecting road wheels to a mechanism to be driven, e.g., in Class 56, Harvesters, are found vehicles carrying cutting mechanism actuated by the road wheels.

SEE OR SEARCH THIS CLASS, SUBCLASS:

6.2+, 21+, 36+, 53.1+, 233+, and 252+, for transmission mechanism of a nature peculiar to the motor vehicles of those subclasses.

53.1+, for transmission combinations with power take-offs, especially 53.2, for creeper drives.

165, for a transmission in combination with a mechanical or fluid accumulator.

200+, for a motor vehicle provided with powered ground engaging means for producing or assisting in the production of lateral movement of the vehicle, (e.g., for parking), and wherein the means comprises a rotatably driven auxiliary wheel or endless track, the drive train for which wheel or track may include the vehicle's transmission. 269, for a motor vehicle having a belt or harness for restraining an occupant and means whereby the belt or harness controls, or is controlled by, the functioning of the vehicle's transmission.

305+, for a motor vehicle which includes a traction motor of the kind driven by a noncompressible fluid which has been placed under pressure by a pump, sometimes referred to as a hydrostatic transmission.

332, 333 and 336, for manually actuated vehicle transmission controls.

SEE OR SEARCH CLASS

56, Harvesters, (See (1) Note).

74, Machine Element or Mechanism, appropriate subclasses, which contain transmission mechanism designed for motor vehicles, but not claimed in connection with specific vehicle structure. For a more detailed statement of this line see (1) Note (b) under the class definition.

105, Railway Rolling Stock, appropriate subclasses, for vehicles of that class having transmission mechanism; and see particularly

96+, for such a vehicle having drive mechanism for a wheel or axle.

111, Planting, (see (1) Note).

172, Earth Working,

35+, for a driven earth working tool, and subclass 292 for an earth working apparatus with some specific propelling means.

280, Land Vehicles, 200+, for general utility occupant propelled-type wheeled land vehicles. In accordance with the (2) Note in Class 280, subclass 200, motorcycle frames and running gear, without features causing classification in Class 180, Motor Vehicles, are included in these subclasses.

474, Endless Belt Power Transmission Systems or Components,

for belt and chain transmissions not claimed in combination with specific vehicle structure.

475, Planetary Gear Transmission Systems or Components, for planetary gear transmission mechanism. The line is the same as with Class 74.

477, Interrelated Power Delivery Controls, Including Engine Control, for interrelated engine and transmission control.
