  • Publication number: 20250001857
    Abstract: A work vehicle has a chassis supported off the ground by ground-engaging wheels or tracks and two transaxles carried by the chassis. The first transaxle has first wheel end units rotatable about a first wheel axis via a first transaxle gear set to rotate a first set of the ground-engaging wheels or tracks. The second transaxle has second wheel end units rotatable about a second wheel axis via a second transaxle gear set to rotate a second set of the ground-engaging wheels or tracks. The second transaxle includes an electric machine having a shaft rotating about a machine axis, a transmission rotated by the electric machine shaft and configured to effect multiple gear ratios at a range gear, and a drive gear rotatable about the second wheel axis by the range gear of the transmission.

  • Publication number: 20250001852
    Abstract: A multi-mode electric transaxle for a work vehicle includes a transaxle housing and wheel end units coupled to the transaxle housing and have hubs rotatable about a wheel axis. An electric machine and a transmission are supported within the transaxle housing. The transmission receives rotational power from the electric machine and is configured to effect multiple gear ratios at a range gear. A drive gear is mounted within the transaxle housing to rotate about the wheel axis and has multiple gear mesh locations, including a first gear mesh location at an outer circumference of the drive gear where the range gear engages the drive gear and a second gear mesh location at an annular face of the drive gear. An output shaft has an inner end mounting an output gear within the transaxle housing to engage the drive gear at the second gear mesh location. The output shaft extends outside the transaxle housing. A transaxle gear assembly couples the drive gear to rotatable the hubs of the wheel end units.

  • Publication number: 20250003489
    Abstract: A work vehicle has two transaxles carried by a chassis each having wheel end units rotatable to drive ground-engaging members about wheel axes and having electric machines powering transmission configured to effect multiple gear ratios. The electric transaxles are operationally mechanically uncoupled. One or more sensors detect speed, heading, and loading characteristics of the work vehicle. A controller, having memory and processing architecture, is configured to process control to: receive from the one or more sensors input of the speed, heading, and loading characteristics of the work vehicle. The controller determines a shift pair sequence for shifting the first transmission and the second transmission based on the received input of the speed, heading, and loading characteristics of the work vehicle.
