Abstract

A drive for a component to be adjusted, in particular for an adjustable automotive vehicle mirror, having a housing which can be mounted on a stationary structure for receiving drive elements, and having an element which encompasses the housing at least partially and is connected to a carrier for the component. The encompassing element with the carrier is disposed pivotably relative to the housing and means for elastic pretension between housing and encompassing element are provided. The means for elastic pretension have a compensating element which is disposed about a central axis of the housing. The compensating element is moveable axially under the effect of a spring force in order to exert a pressure on the carrier and hence on the element encompassing the housing.

Claims

1. A drive for an adjustable automotive vehicle mirror, comprising:

a housing mounted on a stationary structure for receiving drive elements, and

an encompassing element which encompasses the housing at least partially and is connected to a carrier, the encompassing element with the carrier being disposed pivotably relative to the housing and means for elastic pretension between the housing and the encompassing element being provided,

wherein the encompassing element is in frictional contact with the outside surface of the housing containing the drive elements and the means for elastic pretension include a compensating element disposed about a central axis of the housing, the compensating element being moveable axially under the effect of a spring force in order to exert a pressure on the carrier and hence on the element encompassing the housing.

2. The drive according to claim 1, wherein the housing comprises a shell-shaped lower housing and a cover-like upper housing, the compensating element being received in a central recess of the upper housing.

3. The drive according to claim 1, wherein the means for elastic pretension includes at least one spring which acts axially relative to the central axis of the housing is disposed between the compensating element and the housing.

4. The drive according to claim 1, further comprising means for centering the compensating element relative to the housing.

5. The drive according to claim 1, wherein, in the housing, a pin-like sleeve for receiving a mounting screw is disposed about the central axis.

6. The drive according to claim 5, wherein the compensating element has an opening for penetration of the pin-like sleeve.

7. The drive according to claim 1, wherein the compensating element has a plate-like configuration.

8. The drive according to claim 1, wherein the compensating element has a guide comprising two prism-like faces or a curved face.

9. The drive according to claim 8, wherein the carrier is configured as a carrier plate for mounting a mirror and a partial cylinder is moulded centrally on the carrier plate.

10. A drive for an adjustable automotive vehicle mirror, comprising:

a housing mounted on a stationary structure for receiving drive elements, and

an encompassing element which encompasses the housing at least partially and is connected to a carrier for a component, the encompassing element with the carrier being disposed pivotably relative to the housing and means for elastic pretension between the housing and the encompassing element being provided,

wherein the means for elastic pretension include a compensating element disposed about a central axis of the housing, the compensating element being moveable axially under the effect of a spring force in order to exert a pressure on the carrier and hence on the element encompassing the housing;

wherein the means for elastic pretension includes at least two springs which act axially relative to the central axis of the housing and are disposed between the compensating element and the housing, wherein the at least two springs are provided symmetrically to the central axis, and pins for centering the springs being disposed on the compensating element.

11. A drive for an adjustable automotive vehicle mirror, comprising:

a housing mounted on a stationary structure for receiving drive elements, and

an encompassing element which encompasses the housing at least partially and is connected to a carrier for a component, the encompassing element with the carrier being disposed pivotably relative to the housing and means for elastic pretension between the housing and the encompassing element being provided,

the means for elastic pretension include a compensating element disposed about a central axis of the housing, the compensating element being moveable axially under the effect of a spring force in order to exert a pressure on the carrier and hence on the element encompassing the housing;

wherein the compensating element has a guide comprising two prism-like faces or a curved face;

wherein the carrier is configured as a carrier plate for mounting a mirror and a partial cylinder is moulded centrally on the carrier plate;

wherein an anti-rotation element is disposed between the partial cylinder of the carrier plate and the compensating element, said anti-rotation element has a guide orientated towards the partial cylinder and comprises prism-like faces or curved bearing faces, and a partial cylindrical sliding face orientated towards the compensating element.

12. The drive according to claim 11, wherein the compensating element, the anti-rotation element and the partial cylinder of the carrier plate form a rotary bearing for the carrier plate and the encompassing element with the guide.

13. A drive for an adjustable automotive vehicle mirror, comprising:

a housing mounted on a stationary structure for receiving drive elements, and

an encompassing element which encompasses the housing at least partially and is connected to a carrier for a component, the encompassing element with the carrier being disposed pivotably relative to the housing and means for elastic pretension between the housing and the encompassing element being provided,

the means for elastic pretension include a compensating element disposed about a central axis of the housing, the compensating element being moveable axially under the effect of a spring force in order to exert a pressure on the carrier and hence on the element encompassing the housing;

wherein, in the housing, a pin-like sleeve for receiving a mounting screw is disposed about the central axis;

wherein the pin-like sleeve has a plate spring-like projection which is supported against the housing.

14. The drive according to claim 13, wherein the housing comprises a shell-shaped lower housing and a cover-like upper housing, the compensating element being received in a central recess of the upper housing, and wherein the plate spring-like projection is supported on a base of the lower housing and at least one projection moulded on the upper housing forms a limit stop for holding down the plate-like projection.
