Definitions
- the invention relates to an electric drive unit with a stator, which is accommodated in a metal housing, and with a rotor which is rotatable within the stator.
- the stator and rotor form an electrical machine to drive an output member (e.g., flange, shaft) connected to the rotor.
- Such a drive unit may serve as a drive source in a hybrid electric vehicle.
- stator housing metal housing is undesirable consuming.
- This object is achieved by an electric drive unit with the features of claim 1, and in particular by the fact that on the metal housing in the region of the stator, a plastic housing is arranged, which forms at least one cooling channel for a cooling liquid to cool the stator via the metal housing.
- a plastic housing is arranged on the metal housing in the region of the stator.
- the plastic housing forms at least one cooling channel (preferably a plurality of cooling channels) for a cooling liquid (in particular cooling water).
- This cooling Liquid serves to indirectly cool the stator, namely via the metal housing.
- the additional plastic housing simplifies the production of the metal housing and in particular the cooling channels required therefor considerably. Furthermore, the drive unit has a particularly low weight due to the use of a plastic housing.
- the Kunststoffgeffeu- se and the metal housing cooperate to form the one or more cooling channels together.
- the respective cooling channel may be formed completely within the plastic housing.
- the metal housing in the region of the stator forms a peripheral surface
- the plastic housing in the region of the stator forms a lateral surface, which corresponds to the lateral surface of the metal housing and forms an annular gap with this.
- the two lateral surfaces and the separating webs together form the cooling channel (s), i. the respective cooling channel is limited by the lateral surface of the metal housing, the lateral surface of the plastic housing and the said dividers.
- the aforementioned lateral surfaces may in particular be lateral surfaces of a solid cylinder or of a cylinder segment.
- the separating webs can extend along the entire circumference or only part of the circumference of the metal housing or the plastic housing.
- the plastic housing circumferentially surrounds the metal housing in the area of the stator in order ultimately to provide a circumferentially closed cooling water jacket in the annular gap between the jacket and the housing. to form surfaces.
- the plastic housing can also be provided only along a limited peripheral region of the metal housing, corresponding to the aforementioned cylinder segment.
- the cooling channels preferably extend in the circumferential direction with respect to a longitudinal axis of the stator or of the rotor in order to effectively cool the metal housing in the region of the stator and to facilitate the conveyance of the cooling liquid. Relative to this, however, the cooling channels can also run in a spiral or in the axial direction.
- the plastic housing may be formed in one piece.
- the plastic housing is preferably placed in the axial direction (again relative to the longitudinal axis of the stator or the rotor) on the metal housing.
- the plastic housing may be formed in two parts, wherein the dividing plane of the two housing parts preferably extends through the aforementioned longitudinal axis of the stator or rotor.
- the two housing parts in this case may substantially correspond to two half cylinder surfaces.
- the plastic housing has integrated sealing sections. These sealing portions may be formed, for example, in the manufacture of the plastic housing according to an injection molding process by means of injection-molded seals, i. Before injection molding suitable rubber seals are inserted into the mold.
- the plastic housing additionally has a circuit housing section, in which an electrical circuit of the drive unit is received, which is also to be cooled.
- the one or more cooling channels lead to the circuit housing portion to the arranged therein electrical Circuit to cool.
- the electrical circuit can be, for example, a switched-mode power supply, in particular an inverter.
- Circuit housing portion of the plastic housing preferably at least one metal foil or a metal sheet inserted or used.
- the drive unit may comprise a gearbox (in particular a reduction gearbox) and a lubricating fluid circuit for lubricating and / or cooling the gearbox or also the rotor of the electric machine with a separate lubricating fluid (for example lubricating oil).
- a gearbox in particular a reduction gearbox
- a lubricating fluid circuit for lubricating and / or cooling the gearbox or also the rotor of the electric machine with a separate lubricating fluid (for example lubricating oil).
- two liquid circuits are provided in this case, namely the cooling liquid guided in the cooling channels of the plastic housing for cooling the stator from the outside (via the metal housing), and the lubricating fluid guided inside the metal housing.
- said cooling fluid can also serve for cooling the said lubricating fluid.
- the drive unit has a sump for the lubricating fluid, the sump simultaneously forming a heat exchanger for delivering heat from the lubricating fluid (e.g., oil) to the cooling fluid (e.g., water).
- the lubricating fluid e.g., oil
- the cooling fluid e.g., water
- FIGs. 1 and 2 show a respective perspective view of an electric drive unit.
- 3 and 4 show a longitudinal sectional view and exploded view thereof.
- the electric drive unit shown in FIGS. 1 to 4 comprises a metal housing 1 1, which is closed at its two end sides by a respective cover 13, 13 '.
- the metal housing 1 1 is preferably cast from aluminum.
- the drive unit further has a plastic housing 15 with a cylindrical lateral surface 17, which encloses a cylindrical lateral surface 19 of the metal housing 1 1 circumferentially.
- the plastic housing 15 further has a patch on the top, cuboid circuit housing section 21st
- a stator 23 is pressed into the metal housing 1 1.
- a rotor 25 is arranged, which is rotatably connected to an output shaft 27 which is rotatably mounted in the metal housing 1 1.
- the stator 23 and the rotor 25 form an electric machine 29, in particular a three-phase asynchronous machine.
- the electric machine 29 is associated with an inverter 31 disposed inside the circuit housing portion 21.
- the drive unit shown further comprises a spur gear 33, the input side of which is coupled to the output shaft 27 of the electric machine 29 and the output side to a connecting flange 35.
- a special feature of the drive unit shown is that the plastic housing 15 together with the metal housing 1 1 an open cooling water circuit for cooling the stator 23 via the metal housing 1 1 forms.
- a plurality of circumferentially differently extending separating webs 37 are formed on the outer side of the lateral surface 19 of the metal housing 1 1.
- separating webs 37 By the separating webs 37, the outside of the lateral surface 19 of the metal housing 1 1 and the inside of Mantelflä- surface 17 of the plastic housing 15 a plurality of cooling channels 39 are formed, can flow through the cooling water along the lateral surface 19 of the metal housing 1 1 in the circumferential direction.
