Abstract:

A drive assembly for a work vehicle includes a drive housing, a drive shaft rotatable about a drive axis, an inner hub rotationally fixed to the drive shaft, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes a clutch arrangement having a clutch ring configured to selectively engage the planetary gear set. The clutch arrangement further includes a guide assembly mounted on the clutch ring and configured to selectively interact with the planetary gear set to effect disengagement of the clutch ring from the planetary gear set. A clutch actuation assembly is configured to effect movement of the clutch arrangement along the drive axis to engage the planetary gear set, and a guide actuation assembly is configured to operate the guide assembly to interact with the planetary gear set.

International Classification:

F02N 11/04
F02N 15/02
F02N 15/06

Abstract:

A starter-generator device for a work vehicle having an engine includes a gear set for transmitting power, one or more clutch portions configured to selectively interact with the gear set, an actuator device to power movement of an armature only in a first direction, and a linkage having a first portion extending axially and having a neck region formed as a permanent bend and having a bend radius. The linkage also includes a second portion extending radially from the first portion to a distal end. An actuation pin is connected to the distal end and to the clutch portion such that movement of distal end causes corresponding movement of the clutch portion. Powered movement of the armature moves the distal end in one direction. An elastic return force of the linkage moves the distal end in an opposite direction.

Abstract:

A drive assembly for a work vehicle has a drive housing including at least one housing element forming a reaction member, a drive shaft rotatable about a drive axis, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes at least one clutch arrangement having at least one clutch ring configured to selectively interact with the planetary gear set to effect a rotation speed of the output element. At least one actuator is configured to axially drive the clutch ring along the drive axis. A retention mechanism is configured to retain the clutch ring at an axial position along the drive axis. The retention mechanism includes a detent ball, a detent groove and a resilient member configured to urge the detent ball into the detent groove to retain the clutch ring at the axial position.

F16H 3/64
F16D 21/00

Abstract:

A drive assembly for a work vehicle includes a housing arrangement, a drive shaft rotatable in first and second clock directions, and a two-stage planetary gear set coupled to the drive shaft. The gear set includes, or is coupled to, an output element. First and second clutch arrangements are configured to selectively engage the gear set to effect first and second gear ratios, respectively. A step ratio from the first gear ratio and the second gear ratio is 3:1. At least one first actuator and at least one second actuator are configured to effect movement of the first and second clutch arrangements, respectively, to selectively engage the gear set. The drive shaft and the output element rotate in a same clock direction with the first clutch arrangement engaged with the gear set, and in opposite clock directions with the second clutch arrangement engaged with the gear set.

International Classification:

F16H 3/66
F16H 3/00
F16H 61/32

Abstract:

A bi-directional drive assembly for a work vehicle has a reaction member fixed with respect to or a part of a drive housing. A driveshaft is rotatable about a drive axis relative to the reaction member in a first rotation direction and alternatively in a second rotation direction. A planetary set is coupled to the drive shaft and configured to rotate an output hub in the first or second rotation direction. A clutch assembly is coupled to the reaction member and includes a first clutch and a second clutch. The first clutch is configured to interface the planetary set with the reaction member to effect a first rotation speed of the output hub in the first rotation direction and alternatively the second rotation direction. The second clutch is configured to interface the planetary set with the reaction member to effect a second rotation speed of the output hub in the first rotation direction and alternatively the second rotation direction. An actuator arrangement is configured to effect movement of the first clutch and the second clutch along the drive axis to selectively engage the planetary set.
