Abstract

A motor transmission connection arrangement, in particular for use in vehicles, can comprise a motor pot, a brush holder, and a transmission housing. The motor pot, the brush holder and the transmission housing are pluggable to connect with one another, and the motor pot can include a number of centering surfaces, whereby the motor pot with respectively one of the centering surfaces comes into contact both with the brush holder as well as with the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another. The brush holder and the transmission housing can be concentrically oriented to the motor pot. In addition, the present disclosure refers to a sunroof for a vehicle with a motor transmission connection arrangement of this type as well as a vehicle with such a motor transmission connection arrangement.

First claim

What is claimed:

1. A motor transmission connection arrangement, comprising:
a motor pot for the accommodation of an electric motor, the motor pot including centering surfaces;
a brush holder that holds brushes of the electric motor;
a transmission housing that accommodates a transmission;
wherein the motor pot, the brush holder and the transmission housing are pluggable to connect with one another;
wherein the motor pot with respectively one of the centering surfaces comes into contact both with the brush holder as well as the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another; and
wherein the centering surfaces abut against both the brush holder and the transmission housing to concentrically orientate the brush holder and the transmission housing relative to the motor pot;
wherein concentrically orienting the brush holder relative to the motor pot is provided by only the centering surfaces abutting against the brush holder; and
wherein concentrically orienting the transmission housing relative to the motor pot is provided by only the centering surfaces abutting against the transmission housing.

2. The motor transmission connection arrangement according to claim 1 , wherein the motor pot further comprises first contact surfaces that contact the brush holder when the motor pot, the brush holder and the transmission housing are plugged into one another.

3. The motor transmission connection arrangement according to claim 1 , wherein the motor pot further comprises second contact surfaces that contact the transmission housing when the motor pot, the brush holder and the transmission housing are plugged into one another.

4. The motor transmission connection arrangement according to one of the claim 1 , wherein the brush holder includes third contact surfaces that contact the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another.

5. The motor transmission connection arrangement according claim 1 , wherein the motor pot, the transmission housing, or both the motor pot and transmission housing, include crimping sections that connect the transmission housing with the motor pot.

6. The motor transmission connection arrangement according claim 1 , wherein the electric motor operates a vehicle sunroof.

7. The motor transmission connection arrangement according claim 1 , wherein the electric motor operates a vehicle auxiliary drive.

8. The motor transmission connection arrangement according to claim 1 , wherein concentrically orienting the brush holder relative to the motor pot is independent of concentrically orientating the transmission housing relative to the motor pot.

9. The motor transmission connection arrangement according to claim 1 , wherein concentrically orienting the brush holder relative to the motor pot is separate from concentrically orientating the transmission housing relative to the motor pot.

10. A motor transmission connection arrangement, comprising:
a motor pot for the accommodation of an electric motor, the motor pot including centering surfaces;
a brush holder that holds brushes of the electric motor;
a transmission housing that accommodates a transmission;
wherein the motor pot, the brush holder and the transmission housing are pluggable to connect with one another;
wherein the motor pot with respectively one of the centering surfaces comes into contact both with the brush holder as well as the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another, wherein the brush holder and the transmission housing are concentrically oriented to the motor pot;
wherein the motor pot further comprises:
first contact surfaces that contact the brush holder when the motor pot, the brush holder and the transmission housing are plugged into one another;
second contact surfaces that contact the transmission housing when the motor pot, the brush holder and the transmission housing are plugged into one another; and

wherein the brush holder includes third contact surfaces that contact the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another;

wherein the centering surfaces abut against both the brush holder and the transmission housing to concentrically orientate the brush holder and the transmission housing relative to the motor pot;
wherein concentrically orienting the brush holder relative to the motor pot is provided by only the centering surfaces abutting against the brush holder; and
wherein concentrically orienting the transmission housing relative to the motor pot is provided by only the centering surfaces abutting against the transmission housing.

11. The motor transmission connection arrangement according claim 10 , wherein the electric motor operates a vehicle auxiliary drive.

12. The motor transmission connection arrangement according claim 11 , wherein the vehicle auxiliary drive is a vehicle sunroof drive.

13. A motor transmission connection arrangement, comprising:
a motor pot for the accommodation of an electric motor;
a brush holder that holds brushes of the electric motor;
a transmission housing that accommodates a transmission;
wherein the motor pot, the brush holder and the transmission housing are pluggable to connect with one another;
wherein when the motor pot, the brush holder and the transmission housing are plugged into one another, the motor pot comes into contact both with the brush holder and the transmission housing;
wherein the brush holder and the transmission housing are concentrically oriented to the motor pot;
wherein the motor pot further comprises:
first contact surfaces that contact the brush holder when the motor pot, the brush holder and the transmission housing are plugged into one another; and
second contact surfaces that contact the transmission housing when the motor pot, the brush holder and the transmission housing are plugged into one another;

wherein the centering surfaces abut against both the brush holder and the transmission housing to concentrically orientate the brush holder and the transmission housing relative to the motor pot;
wherein concentrically orienting the brush holder relative to the motor pot is provided by only the centering surfaces abutting against the brush holder; and
wherein concentrically orienting the transmission housing relative to the motor pot is provided by only the centering surfaces abutting against the transmission housing.

14. The motor transmission connection arrangement according claim 13 , wherein the brush holder includes third contact surfaces that contact the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another.

15. The motor transmission connection arrangement according claim 13 , wherein the electric motor operates a vehicle sunroof.
