Abstract
A transmission system is described having a first gear ratio coupling a forward clutch and a first shaft to an intermediate shaft, a second gear ratio coupling a reverse clutch and a first shaft to the intermediate shaft, and a third gear ratio coupling the intermediate shaft to an output shaft.
Claims18
A transmission system, comprising:
- a first gear ratio coupling a forward clutch and a first shaft to an intermediate shaft;
- a second gear ratio coupling a reverse clutch and the first shaft to the intermediate shaft;
- a third gear ratio coupling the intermediate shaft to an output shaft, the output shaft extending from the transmission system;
- and
- an output of a mover, the output surrounding the first shaft, wherein the forward clutch locks the first shaft to a first gear of the first gear ratio and the reverse clutch locks the first shaft to a second gear of the second gear ratio,
- wherein the second gear ratio includes an idler shaft which couples the reverse clutch to the intermediate shaft, wherein the first shaft is a forward reverse shaft and the forward clutch and the reverse clutch surround the first shaft, and wherein the first shaft supports the forward clutch and the reverse clutch via bearings.

A transmission system, comprising:
- a first gear ratio coupling a forward clutch and a first shaft to an intermediate shaft;
- a PTO output gear;
- an output of a prime mover, wherein the first shaft is mechanically coupled to and surrounded by the output and is located above the intermediate shaft;
- a second gear ratio coupling a reverse clutch and the first shaft to the intermediate shaft;
- and
- a third gear ratio coupling the intermediate shaft to an output shaft, wherein the PTO output gear circumferentially surrounds the output of the prime mover and the first shaft,
- wherein the second gear ratio includes an idler shaft which couples the reverse clutch to the intermediate shaft, wherein the first shaft is a forward reverse shaft and the forward clutch and the reverse clutch surround the first shaft, and wherein the first shaft supports the forward clutch and the reverse clutch via bearings.
