Abstract
An electric drive unit includes a stator which is received in a metal housing, and a rotor rotates within the stator. A synthetic material housing is arranged on the metal housing in the region of the stator, the synthetic material housing forming at least one cooling channel for a cooling fluid in order to cool the stator via the metal housing.
Claims17
An electric drive unit comprising:
- a first housing composed of metal;
- a stator received in the first housing;
- a rotor which rotates relative to the stator;
- a second housing composed of a synthetic material and provided on the first housing in a region adjacent to the stator, wherein the second housing forms at least one fluid channel through which flows a fluid which cools the stator via the first housing;
- a transmission;
- and
- a second fluid channel through which flows a second fluid which lubricates and cools the transmission.
4 more elements
A drive unit comprising:
- a motor;
- a first housing configured to receive the motor and composed of a first material;
- a second housing composed of a second material which is different than the first material;
- a transmission;
- a fluid channel in the first housing through which flows a fluid which cools the motor via heat exchange with the first housing during operation of the drive unit;
- and
- a second fluid channel through which flows a second fluid which lubricates and cools the rotor.
4 more elements
A drive unit comprising:
- a motor having a stator;
- a first housing compose of a first material, the first housing configured to receive the electric motor, the peripheral surface of the first housing having a plurality of webs spaced apart from each other;
- a second housing composed of a second material which is different than the first material;
- a plurality of first fluid channels formed by the webs and the second housing and through which flows a fluid which cools the stator via heat exchange with the first housing during operation of the drive unit;
- a transmission;
- and
- a second fluid channel through which flows a second fluid which lubricates and cools the transmission and the rotor.
