A drive axle of a vehicle includes an electric motor having an output shaft. At least one of a gear and a planetary gear set is operably connected to the output shaft of the electric motor. The at least one of the gear and the planetary gear set is operably connected to a differential configured to transfer torque to two axle half shafts of the vehicle. At least one clutch configured to facilitate a plurality of gear ratios between the electric motor and the differential.

A transmission may include an input shaft, a first output shaft, a second output shaft, a first planetary gearset, and a second planetary gearset connected to the first planetary gearset, where the planetary gearsets each comprise numerous elements. The input shaft, the two output shafts, the planetary gearsets, and their elements may be arranged and designed such that a torque input via the input shaft is converted and distributed in a defined ratio to the two output shafts, and the formation of a combined torque is prevented. At least a third element of the first planetary gearset may be connected to a first element of the second planetary gearset via a shaft for conjoint rotation.

A transfer case having, a transmission mount, an input shaft received through the transmission mount, an electric propulsion motor, a transfer case portion and a transmission portion. The transfer case portion has a transfer case portion input, a first transfer case portion output, a second transfer case portion output, and a power transfer mechanism, the first transfer case portion output being drivingly coupled to the transfer case input portion, the power transfer mechanism drivingly coupling the second transfer case portion output to the first transfer case output portion. the transmission portion has a first coupling, which is selectively operable for drivingly connecting the input shaft to the transfer case portion input, and a second coupling that is selectively operable for drivingly connecting a rotor of the electric propulsion motor to the transfer case portion input.

Methods and systems are provided for a multi-speed transmission. The multi-speed transmission includes a housing, an electric motor with a stator and a rotor positioned within the housing, and a planetary assembly positioned on a first axial side of the electric motor. The transmission further includes a first and second clutch unit spaced away from one another, each including a synchronizer, and designed to selectively rotationally couple to the rotor and to rotationally couple the rotor to different gears in the planetary assembly and where the electric motor and planetary assembly are coaxially arranged.

A gearbox arrangement of an electric machine of an engine includes a planetary gear arrangement configured to receive rotational input from the electric machine and from the engine and to mechanically couple the electric machine and the engine in first and second power flow directions, the planetary gear set comprising a ring gear, a ring brake, a free-wheel clutch attachable to a fixed structure and the ring brake, the tree-wheel clutch permitting rotation of the ring brake in a first direction and preventing rotation of the ring brake in an opposite second direction, and an arrangement for moving the ring gear between a first position in which the ring gear is non-rotatably engaged with the ring brake and a second position in which the ring gear is non-rotatably engaged with the carrier. An engine starter and power generator device Is also provided.

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.

A powertrain apparatus includes a motor connected to an input shaft, a first planetary gear train, which is disposed to be coaxial with the motor and which includes a first rotation element, a second rotation element, and a third rotation element, a second planetary gear train, which is disposed to be coaxial with the first planetary gear train and which includes a fourth rotation element, a fifth rotation element, a sixth rotation element, and a step pinion, and a differential gear, which is disposed to be coaxial with the second planetary gear train.

A pipette calibration and volume offset mechanism. The calibration and volume offset mechanism is provided to facilitate user selectable calibration or volume offset operations of a pipette to which the calibration and volume offset mechanism is installed, through axial displacement of a threaded element that effectively moves the home position of the pipette. An offset counter of the calibration and volume offset mechanism is rotationally coupled to the threaded element during a volume offset operation to indicate offset magnitude, but decoupled from threaded element during a calibration or recalibration operation.
