Abstract

A suspension for an assembly generating, absorbing, and/or transmitting torque in the drive train of a motor vehicle with a combustion engine, with the assembly 10 including materials with a thermal expansion coefficient different from the material of the engine block of the combustion engine 12, and a first non-rotating part 18, 22 of the assembly 10 being connected with the engine block, and a second rotating part 16 of the assembly 10 being connected with an output shaft 14 protruding from the engine block, and with the first and the second part 18, 22; 16 being designed so as to encompass the output shaft 14 at least partially, and with the first non-rotating part 18, 22 of the assembly 10 being connected with the engine block of the combustion engine 12 via a coupling element 40 in a manner so as to be essentially secured against rotation and resilient in the radial direction.

Claims

1. A suspension for an assembly generating, absorbing, and/or transmitting torque in a drive train of a motor vehicle with a combustion engine having an engine block, with

a first non-rotating part (18, 22) of the assembly (10) being connected with the engine block of the combustion engine (12) via a coupling element (40;

50) in a manner so as to be essentially secured against rotation, and a second rotating part (16) of the assembly (10) being connected with an output shaft (14) protruding from the engine block, and with

the first and the second part (18, 22;

16) being designed so as to encompass the output shaft (14) at least partially, characterized in that

the assembly (10) comprises materials with a thermal expansion coefficient different from that of the material of the engine block of the combustion engine (12), and

the coupling element is a disk (40) which extends in an essentially radial direction, at which at least one flange (42) is formed oriented essentially coaxially with the output shaft (14), which can be deformed in the radial direction, with the disk (40) being connected with the engine block and the flange (42) being connected with the first non-rotating part (18), the coupling element (40;

50) thereby being is resilient in the radial direction so that it is readily deformed under thermal expansion/contraction.

2. The suspension according to claim 1, characterized in that

the assembly is an electric motor (10) with the first non-rotating part being a stator (18) and the second rotating part being a rotor (16) of the electric motor.

3. The suspension according to claim 2, characterised in that

at least one radially oriented web (44) which is arranged at least along a portion of the circumference of the flange is formed at the end of each flange (42), which is remote from the disk (4), which connects the flange (42) with the first non-rotating part (18) of the assembly (10).

4. The suspension according to claim 3, characterised in that

the outer surface of the first non-rotating part of the assembly, the end of each flange and the webs define an annular space (46) through which a cooling fluid can flow.

5. The suspension according to claim 3, characterised in that

the disk is formed by two annular joined sheet metal parts at whose radially inner edges an axially oriented flange is formed, with a radially oriented web being formed at an edge of said flange which is remote from the disk.

6. The suspension according to claim 2, characterised in that

the flange is integrally connected with the first non-rotating part of the assembly with an end of said flange which is remote from the disk.

7. The suspension according to claim 1, characterised in that

the flange is integrally connected with the first non-rotating part of the assembly with an end of said flange which is remote from the disk.

8. The suspension according to claim 1, characterised in that

at least one radially oriented web (44) which is arranged at least along a portion of the circumference of the flange is formed at the end of each flange (42), which is remote from the disk (4), which connects the flange (42) with the first non-rotating part (18) of the assembly (10).

9. The suspension according to claim 8, characterised in that

the outer surface of the first non-rotating part of the assembly, the end of each flange and the webs define an annular space (46) through which a cooling fluid can flow.

10. The suspension according to claim 8, characterised in that

the disk is formed by two annular joined sheet metal parts at whose radially inner edges an axially oriented flange is formed, with a radially oriented web being formed at an edge of said flange which is remote from the disk.

11. A suspension for an assembly generating, absorbing, and/or transmitting torque in a drive train of a motor vehicle with a combustion engine having an engine block, with

a first non-rotating part (18, 22) of the assembly (10) being connected with the engine block of the combustion engine (12) via a coupling element (40;

50) in a manner so as to be essentially secured against rotation, and a second rotating part (16) of the assembly (10) being connected with an output shaft (14) protruding from the engine block, and with

the first and the second part (18, 22;

16) being designed so as to encompass the output shaft (14) at least partially, characterized in that

the assembly (10) comprises materials with a thermal expansion coefficient different from that of the material of the engine block of the combustion engine (12), and

the coupling element is a radially oriented collar (50) is arranged at the outer circumference of the first non-rotating part, which comprises several elongated holes (52) along its circumference, adjacent to which holes (54) are arranged further radially outward, an d webs (56) which are resilient in the radial direction are formed further radially inward, the coupling element (40;

50) thereby being resilient in the radial direction so that it is readily deformed under thermal expansion/contraction.
