Abstract
A bearing assembly for supporting a unit of a motor vehicle includes at least two first bearings, each of which has a line and an attachment element. Each of the lines is attached to a line attachment point on the unit. The lines are fixed to a structural component of the motor vehicle by means of the attachment elements, and each of the first bearings has a respective bearing rigidity such that forces produced by the rotation of the unit and introduced into the structural component of the vehicle via the first bearings cancel each other out.

A bearing assembly for supporting a unit of a motor vehicle on a structural component of the motor vehicle, comprising:
- two first bearings, wherein
- the two first bearings each comprise a line and a rigid attachment element,
- each line is attached at one end to the unit at a line attachment point and is directly attached at the other end to the rigid attachment element for fixation to the structural component of the motor vehicle,
- the two first bearings each have a bearing stiffness which acts symmetrically with respect to a center of gravity of the unit such that forces which are caused by rotation of the unit and which are introduced into the structural component of the vehicle by way of the two first bearings cancel out one another, so as to reduce vibrational acoustics,
- wherein the stiffness of the two first bearings is defined by a material stiffness of the attachment element, a geometry of the attachment element, a material stiffness of the line, and a geometry of the line.
