Abstract

Claims (29)

1. A bearing assembly for supporting a unit of a motor vehicle on a structural component of the motor vehicle, comprising:

four bearings, each with an elastic center,

wherein the four bearings are arrangeable on the structural component of the motor vehicle such that the elastic centers thereof together span a two-dimensional area in which a center of mass of the unit to be supported is located;

wherein the spanned two-dimensional area comprises two axes of symmetry running orthogonally with respect to one another and intersecting at the center of mass of the unit to be supported;

wherein the four bearings have a same bearing stiffness; and

wherein the unit is connected directly to the structural component via the four bearings.

2. The bearing assembly according to claim 1 , wherein

respective ones of the four bearings which lie opposite one another in relation to the center of mass of the unit to be supported are attached to the same structural component of the motor vehicle.

3. The bearing assembly according to claim 1 , wherein

the four bearings are attached to the same structural component of the motor vehicle.

4. The bearing assembly according to claim 1 , wherein a sum of the bearing locations is an even number.

5. The bearing assembly according to claim 1 , wherein

the two-dimensional area is a rectangle, a square, a rhombus or a polygon with an even number of corners.

6. A bearing assembly for supporting a unit of a motor vehicle on a structural component of the motor vehicle, comprising:

four bearings, each with an elastic center,

wherein the four bearings are arrangeable on the structural component of the motor vehicle such that the elastic centers thereof together span a two-dimensional area in which a center of mass of the unit to be supported is located;

wherein the four bearings are arranged with their elastic centers spanning a two-dimensional area which comprises at least two axes of symmetry with respect to the unit, and which run orthogonally with respect to one another, and which intersect at the center of mass of the unit,

wherein a first bearing of the four bearings is arranged, relative to the other bearings of the four bearings, displaced in the direction of the center of mass of the unit or away from the center of mass of the unit,

wherein the bearing stiffness of the four bearings is designed such that oscillations of the vehicle structure that are produced by forces which are introduced into the vehicle structure by way of the bearing assembly and which result from a rotational movement of the unit cancel one another out; and

wherein the unit is connected directly to the structural component via the four bearings.

7. The bearing assembly according to claim 6 , wherein

the bearing stiffness of the four bearings is greater the closer they are to the center of mass of the unit.

8. The bearing assembly according to claim 6 , wherein

respective ones of the four bearings which lie opposite one another in relation to the center of mass of the unit to be supported are attached to the same structural component of the motor vehicle.

9. The bearing assembly according to claim 6 , wherein

the four bearings are attached to the same structural component of the motor vehicle.

10. The bearing assembly according to claim 8 , wherein a sum of the bearing locations is an even number.

11. The bearing assembly according to claim 6 , wherein

the two-dimensional area is a rectangle, a square, a rhombus or a polygon with an even number of corners.
