Integrated starter-generator device with unidirectional clutch actuation utilizing biased lever assembly

A combination starter-generator device for a work vehicle having an engine, the combination starter-generator device comprising:

• a housing arrangement forming a reaction member;
• a gear set configured to transmit power flow to and from the engine;
• a clutch arrangement configured to selectively interact with the gear set to modify power flow through the gear set;
• an actuator device having an armature, the actuator device operable to power movement of the armature in a first axial direction to apply a push force;
• a linkage coupled between the actuator device and a portion of the clutch arrangement, the linkage having a first end proximal to the reaction member, a first portion extending from the first end, and a second portion extending radially from the first portion to a second end, the first portion having a neck region formed as a permanent bend having a bend radius, and the second portion having a coupling region configured to interact with the armature, a stiffened region, and a connection region at the second end;
• and
• an actuation pin connected to the connection region and the portion of the clutch arrangement,
• wherein the linkage is formed from a flexible resilient material and is movable in a powered stroke from an undeformed, unloaded condition to an elastically deformed, loaded condition by application of the push force, and is movable in a return stroke from the elastically deformed, loaded condition to the undeformed, unloaded condition under an elastic return force with the push force removed,
• wherein the second end is displaced in the first axial direction or a second axial direction in the powered stroke to reposition the portion of the clutch arrangement in the same one of the first axial direction or the second axial direction,
• wherein the second end is moved in the other of the first axial direction or the second axial direction in the return stroke to reposition the portion of the clutch arrangement in the same other of the first axial direction or the second axial direction, and
• wherein the first portion further includes a mounting region configured to receive a fastener for securing the linkage to the reaction member, wherein the mounting region has a first width and the neck region has a second width less than the first width.

A combination starter-generator device for a work vehicle having an engine, the combination starter-generator device comprising:

• a housing arrangement forming a reaction member;
• an input shaft extending within the housing arrangement, the input shaft rotatable on a drive axis;
• a sliding shaft rotationally fixed to the input shaft and axially slidable relative to the input shaft;
• a gear set configured to transmit power flow to and from the engine, wherein the gear set interfaces with the sliding shaft for rotation;
• a first clutch shiftable into a disengaged position in which the first clutch is decoupled from the gear set and into an engaged position in which the first clutch is coupled to the gear set to effect a first gear ratio;
• a first actuator device having a first armature, wherein the first actuator device is energized to power movement of the first armature to apply a first push force in a first axial direction and is deenergized to remove the first push force;
• a first linkage having a first portion secured to the reaction member and extending axially away from the reaction member, and a second portion extending radially inward from the first portion of the first linkage to a first distal end, the first portion of the first linkage including a first neck region formed as a permanent bend having a first bend radius and a reduced width relative to the second portion of the first linkage, wherein the first distal end is movable in a second axial direction in response to the first push force applied to the second portion of the first linkage to move the first linkage from an undeformed, unloaded condition to an elastically deformed, loaded condition, and wherein the first distal end is movable in the first axial direction under an elastic return force of the first linkage in response to removal of the first push force from the second portion of the first linkage, to move the first linkage from the elastically deformed, loaded condition to the undeformed, unloaded condition;
• a first actuation pin connected to the first distal end of the first linkage and the first clutch such that movement of the first distal end in the first axial direction or the second axial direction causes movement of the first actuation pin to reposition the first clutch in the same one of the first axial direction or the second axial direction;
• a second clutch shiftable into a disengaged position in which the second clutch is decoupled from the gear set and into an engaged position in which the second clutch is coupled to the gear set to effect a second gear ratio higher than the first gear ratio;
• a second actuator device having a second armature, wherein the second actuator device is energized to power movement of the second armature to apply a second push force in the first axial direction and is deenergized to remove the second push force;
• a second linkage having a first portion secured to the reaction member and extending axially away from the reaction member, and a second portion extending radially inward from the first portion of the second linkage to a second distal end, the first portion of the second linkage including a second neck region formed as a permanent bend having a second bend radius and a reduced width relative to the second portion of the second linkage, wherein the second distal end is movable in the first axial direction in response to the second push force applied to the second portion of the second linkage to move the second linkage from an undeformed, unloaded condition to an elastically deformed, loaded condition, and wherein the second distal end is movable in the second axial direction under an elastic return force of the second linkage in response to removal of the second push force from the second portion of the second linkage to move the second linkage from the elastically deformed, loaded condition to the undeformed, unloaded condition;
• and
• a second actuation pin connected to the second distal end of the second linkage and the second clutch such that movement of the second distal end in the first axial direction or the second axial direction causes movement of the second actuation pin to reposition the second clutch in the same one of the first axial direction or the second axial direction.
