ABSTRACT:
A reverser unit including a carrier having a forward double planetary pinion rotatably mounted thereon located in a forward section of an enclosing housing. The first planetary pinion of the double planetary is sized larger than a second planetary pinion of the double planetary pinion. A first sun gear coupled to a sun shaft is in constant mesh with the first planetary pinion and a second sun gear rotatably mounted on the sun shaft is in constant mesh with the second planetary pinion. A clutch drum is coupled to the second sun pinion and is generally located in the rear section of said housing. The clutch drum is coupled to a brake clutch system in the rear section of the housing for selectively braking the clutch drum to the housing. A clutch hub is coupled to the sun shaft in the rear section of the housing. A clutch system in the rear section of the housing can selectively clutch the clutch hub to the clutch drum. A detachably mounted housing rear cover is detachable to allow the withdrawal of the brake clutch and hub clutch system without further disassembly of the reverser.
