Abstract: A brake includes a rotor rotatably coupled to a rotating body for rotation about a rotational axis. A brake plate and an armature are disposed on opposite sides of the rotor. A spring and an electromagnet urge the armature in opposite directions into and out of engagement with the rotor to move the rotor into and out of engagement with the brake plate and engage and disengage the brake. The brake plate and electromagnet each define a central bore configured to receive the rotating body. The brake is characterized by a target supported on a radially extending face of the rotating body or the rotor and a sensor aligned with the target through the central bore of the brake plate or the electromagnet. The sensor generates, responsive to the target, position signals indicative of a rotational position of the rotor and rotating body.

Abstract: An electric drive axle with an electric motor having a motor shaft that is rotatable about an axis, a differential, and a transmission. The transmission transmits rotary power between the motor shaft and the differential. The multi-speed reduction has an input shaft and at least three on-axis gears. The input shaft is rotatably coupled to the motor shaft. Each of the at least three on-axis gears is co-axial with the input shaft and is rotatable relative to the input shaft in at least one of a first speed ratio and a second speed ratio. The input shaft is axially movable along the axis between a first position, in which a first one of the at least three on-axis gears is rotationally coupled to the input shaft, and a second position in which a second one of the at least three on-axis gears is rotationally coupled to the input shaft.
