Electric drive module with independent drive units having friction brakes that are selectively engageable to one another

An electric drive module that includes a housing, a pair of drive units and a coupling unit. The drive units are disposed in the housing and each drive unit includes a motor unit and a friction brake. The motor unit has a stator, which is non-rotatably coupled to the housing, and a rotor that is rot...

Beschreibung
Zusammenfassung:	An electric drive module that includes a housing, a pair of drive units and a coupling unit. The drive units are disposed in the housing and each drive unit includes a motor unit and a friction brake. The motor unit has a stator, which is non-rotatably coupled to the housing, and a rotor that is rotatable about a motor axis and configured to drive a wheel of a vehicle. The friction brake has a first portion, which is non-rotatably coupled to the housing, and a second portion that is drivingly coupled to the rotor. The friction brake can be operated to create a rotational drag force that resists rotation of the second portion relative to the first portion. The coupling unit is configured to selectively rotatably couple the second portions of the friction brakes to one another.
