Transmission arrangement for harvesting vehicles

摘要

A transmission arrangement is disclosed for a cotton harvester. A power take-off shaft may be configured to receive rotational power from an engine of the cotton harvester. An infinitely variable transmission may be configured to sum mechanical power from an infinitely variable power source and the engine and to output the summed power at a variable output shaft. A clutch arrangement may be configured, in a first state, to disconnect a harvesting unit of the cotton harvester from the power take-off shaft and route power from the variable output shaft to the harvesting unit. The clutch arrangement may be further configured, in a second state, to disconnect the harvesting unit from the variable output shaft and route power from the engine to the harvesting unit via the power take-off shaft.

1. A transmission arrangement for a cotton harvester with an engine, a ground-engaging element for moving the cotton harvester over a field, and at least one harvesting unit for gathering cotton, the transmission arrangement comprising:
a power take-off shaft configured to receive rotational power from the engine; an infinitely variable transmission configured to sum mechanical power from an infinitely variable power source and the engine and to output the summed power at a variable output shaft; and a clutch arrangement configured to:
in a first state, disconnect the harvesting unit from the power take-off shaft and route power from the variable output shaft to the harvesting unit; andin a second state, disconnect the harvesting unit from the variable output shaft and route power from the engine to the harvesting unit via the power take-off shaft.
