Embodiment Construction

[0019] exist Figure 1 to Figure 3 shows different views of possible implementation variants of an electric machine according to the invention for use in a vehicle, in particular a motor vehicle. The electric machine comprises a stator 1 and a rotor 2 arranged in a housing 3 . The rotor 2 rotates about the axis of rotation 4 and drives the wheel, the rotor 2 being mounted in the housing 3 via a first rotor bearing 5 and a second rotor bearing 6 .

[0020] In order to cool the stator 1, which extends around the rotor 2 and is firmly connected to the housing 3, a jacket cooling is provided as a liquid cooling, which is realized, for example, by a plurality of helical cooling channels 7 which extend through the cooling jacket 8 and extends around the stator 1.

[0021] For a more efficient design and a particularly cost-effective and structurally simple realization of the liquid cooling, provision is made to provide a surface cooler 10 connected to the liquid cooling via the ho...

Abstract

An electric machine includes a stator (1) and a rotor (2), which are arranged in a housing (3). A liquid cooling jacket is configured for cooling the stator (1). At least one extended surface cooler (10), which is connected to the liquid cooling jacket via a housing wall, is provided in an interior of the housing (3) for direct cooling of components arranged in the interior of the housing (3). Theinvention also provides a vehicle axle drive that may include the electric machine.

Description

technical field [0001] The invention relates to an electrical machine of the type defined in the preamble of claim 1 , having a stator and a rotor. Furthermore, the invention also relates to a vehicle with the electric machine. Background technique [0002] A vehicle with a generator is known, for example, from publication EP 0 231 785 A2. To cool the stator of the generator, a jacket cooling is provided which is supplied with coolant from the vehicle. The jacket cooling section can provide indirect cooling of other components through additional heat conducting elements. In addition, the fan impeller that generates the cooling air flow will be driven. [0003] Since adequate dissipation of the heat generated is important for the effective power of the electric machine, in particular electric machines operated as electric motors require adequate liquid cooling. In addition to the cooling of the temperature-regulated stator by means of the jacket, a large number of other h...
