Abstract
An electric drive unit with an electric machine arranged in a motor housing. The electric machine has a rotor and a stator. A transmission is arranged in a transmission housing and driven by the electric machine. A cooling sleeve is provided, which forms a radially outward facing hollow space for a coolant by virtue of a spiral-shaped circumferential web between itself and the surrounding motor housing. Furthermore the cooling sleeve has a holding web which is designed to be clamped between two motor housing components.
