Embodiment Construction

[0023] Figures 1 to 3 The arrangement according to the invention of the electric motor unit 10 in the motor compartment of the motor vehicle is shown, wherein only the essential elements in the motor compartment of the motor vehicle are shown.

[0024] The electric motor unit 10 includes an electric motor (not visible), which is directly connected at its output-side end to a transmission 12 . Furthermore, the electric motor is surrounded by a housing in which a cooling jacket (not visible) is integrated in the region of the electric motor (middle part 14 of the housing). At the end of the electric motor opposite the transmission 12 , the housing includes an end section 16 which is connected to the middle part 14 of the housing by means of numerous screw connections. The end section 16 forms a free space with the adjacent end of the electric motor, inside which three connecting lines (not visible) run for the electric motor operated with three-phase alternating current. Due ...

Abstract

The invention relates to an arrangement of an electric motor unit (10) in the motor compartment of a motor vehicle. The electric motor unit (10) comprises an electric drive motor, a housing which surrounds the drive motor, and a transmission (12) which is flange-mounted directly on the drive motor. The electric motor unit (10) is suspended on at least two assembly supports (22), a first assembly support (22) being fixed to the transmission (12) and a second assembly support (22) being fixed to the housing. According to the invention, at least two additional assembly bearings (36) are provided, which connect the electric motor unit (10) to a subframe (50) of the motor vehicle, a first assembly bearing (36) being fixed to the transmission (12) and a second assembly bearing (36) being fixed to the housing.

Description

technical field [0001] The invention relates to an arrangement of an electric motor unit in a motor compartment of a motor vehicle, wherein the electric motor unit comprises an electric drive motor, a housing surrounding the drive motor and a direct flange connection to the drive motor. The transmission on the drive motor, wherein the electric motor unit is suspended from at least two unit brackets, wherein a first unit bracket is fixed to the transmission and a second unit bracket is fixed to the housing . Background technique [0002] Such an arrangement is known, for example, from DE 10 2009 040 896 A1. There, the electric motor unit is suspended via a suspension arm, which is connected to a transverse support, which in turn is fastened to the vehicle body. In addition to the two unit supports (via which the electric motor unit is suspended), the suspension there also includes a swing support, which acts with one end on the section of the transmission near the floor and...
