International Classification:

F16H061/00
F16H059/00

US Classification:

474 70, 474 73, 56 103

Abstract:

A two speed shift mechanism for a belt drive that includes a rotatable shaft with a first pulley, and a tube concentric with the shaft and rotatable therearound. The tube includes a shift hub supporting a second pushy in axially spaced relation to the first pulley for concentric rotation about the shift hub. The mechanism further includes a collar mounted around the shift hub for rotation therewith and for axial movement between a position adjacent the first pulley and a position adjacent the second pulley. In a first position, the collar and the first pulley include elements engageable for connecting the collar to the first pulley for rotation of the collar, the shift hub, and the tube. In a second position, the collar and the second pulley include elements engageable for connecting the collar to the second pulley for rotation of the collar, the shift hub, and the tube.

Nicholas Laufenberg - Darien IL, US

Assignee:

CNH America LLC - New Holland PA

International Classification:

A01D 75/18

US Classification:

460 6, 460 1

Abstract:

A system to sense incipient slugging of a rotor by sensing a rotor speed signal, an engine speed signal and a first hydraulic motor speed signal, combining the rotor speed signal and the engine speed signal to provide a second hydraulic motor speed signal, and determining incipient slugging based upon the first and second speed signals, and thereby preventing potential damage to threshing components.

Peter Ungs - Bolingbrook IL, US

International Classification:

F16H007/02

US Classification:

474/073000, 192/069910

Abstract:

A two speed shift mechanism for a belt drive, including a rotatable shaft including a first pulley mounted thereon for rotation therewith, a tube concentric with the shaft and rotatable therearound, the tube including a shift hub mounted around a portion thereof for rotation therewith, and the shift hub supporting a second pulley in axially spaced relation to the first pulley for concentric rotation about the shift hub. The mechanism includes a collar mounted around the shift hub in the space between the pulleys for rotation with the shift hub and for axial movement relative thereto between a position adjacent the first pulley and a position adjacent the second pulley. The collar and the first pulley include elements cooperatively engageable when the collar is in the first position for connecting the collar to the first pulley for rotation of the collar, the shift hub and the tube therewith, and the collar and the second pulley include elements cooperatively engageable when the collar is in the second position for connecting the collar to the second pulley for rotation of the collar, the shift hub, and the tube therewith, the mechanism further optionally including a releasable element for holding the collar in the first and second positions, respectively.

Abstract:

A header which is couplable with a base unit of an agricultural harvester. The header includes a rotatably driven first sub-system, a rotatably driven second sub-system, a first input drive, and a second input drive. The first input drive is mechanically couplable with the base unit. The first input drive is configured for driving the first sub-system at a first operating speed. The second input drive is mechanically couplable with the base unit. The second input drive is configured for driving the second sub-system at a second operating speed which is independent of the first operating speed.
