Embodiment Construction

[0039] figure 1 Shown is a highly simplified cross-sectional view of a variant embodiment of an acoustic capsule 1 according to the invention arranged around an electric motor 2 of an electric vehicle (not shown). In addition to other components not shown in detail here, the electric motor 2 also has a drive shaft 3 and a base plate 4 .

[0040] In this variant embodiment, the capsule 1 has a cuboid shape and consists of 6 individual soundproof capsule elements 10 connected to each other. The capsule elements 10 are connected to each other eg by pins and pin sockets not shown. In order to establish a connection between the individual capsule elements 10 , they are inserted into each other and positioned around the electric motor 2 .

[0041] The capsule 1 also comprises a fastening element 20 which is also designed in the form of a pin. These fastening elements are integrally connected to the upper bladder element 10 forming the cover and extend from the inner surface 11 of...

Abstract

The invention relates to an acoustically and thermally effective capsule (1) for an electric motor (2) in a motor vehicle, in particular an electric vehicle, comprising: a plurality of acoustically and thermally effective capsule elements (10) that can be connected to each other; and at least one fastening element (20) for securing the capsule (1) to a housing of the electric motor (2).

Description

technical field [0001] The invention relates to a sound-insulating and heat-insulating bladder for an electric motor of a motor vehicle, in particular an electric vehicle. With the sound-insulating and heat-insulating bladder according to the invention, the noise emissions from electric motors known from the prior art can be significantly reduced, wherein at the same time the formation of condensate is effectively reduced and thus the accumulation of condensate formed on the electric motor is avoided . Background technique [0002] In the sense of the present application, an electric vehicle is understood to be both a purely electrically driven motor vehicle and a so-called hybrid variant, ie a motor vehicle comprising an internal combustion engine and at least one electric drive motor. [0003] Although electric motors known from the prior art are already many times quieter than internal combustion engines, further reductions in noise emissions, especially in the interior ...
