U.S. Patent Number: 5383374

Abstract: A compound change gear transmission (11) is disclosed, of the type including a front main transmission section (13), and a rear auxiliary transmission section (15). The front section includes a countershaft (29) and a rear section includes a rear wall portion (33). A power-take-off (PTO) device (61;141) includes a PTO input shaft (81) extending through the rear wall portion (33) and being clutched (85) to a rearward end portion (73) of the front section countershaft (29). The PTO device includes an actuator (109,115) extending through the rear wall portion (33) and operable to move the clutch means (85) between disengaged and engaged positions. In one embodiment (FIG. 6), the PTO device (141) includes a gear train comprising a ring gear (145) and a pinion gear (167) which drives a PTO output yoke (161). The present invention provides a PTO device and clutching arrangement which is substantially reduced in overall size and complexity, and reduces the overall installed length of the transmission.
