Abstract

A drive arrangement for actuating a hatch of a motor vehicle with a drive for producing driving having a drive motor for producing movement of the hatch between an open position and a closed position and having a transmission linkage connected on the output side of the motor. The transmission linkage has a first driven lever and a second driven lever for transmission of pushing forces and/or pulling forces to the hatch, and the driven levers, in the installed state, converge on a joint arrangement which is located on the hatch and are coupled to it by drive engineering in a manner such that the lines of dynamic effect of the two driven levers form an included angle with one another which corresponds to the respective position of the hatch.

Claims

1. Drive arrangement for actuating a hatch of a motor vehicle, the hatch being coupled to the body to pivot around a hatch axis for opening and closing a hatch opening of the body, the drive arrangement comprising:

a drive for producing drive motions having a drive motor and a transmission linkage connected on an output side of the drive motor for producing, in an installed state, movement of the hatch between an open position and a closed position,

wherein the transmission linkage has a first driven lever and a second driven lever for transmission of movement forces to the hatch, the driven levers converging on a joint arrangement which is located, in the installed state, on the hatch, the driven levers being coupled to the joint arrangement in a manner that lines of dynamic effect of the two driven levers form an included angle between them which, in the installed state, corresponds to the respective position of the hatch.

2. Drive arrangement as claimed in claim 1, wherein a angle bisector of said included angle lies essentially in a vertically aligned plane which intersects a central lengthwise axis of the motor vehicle in the installed state.

3. Drive arrangement as claimed in claim 1, wherein the movement forces acting on the hatch from the drive arrangement are perpendicular to the hatch axis.

4. Drive arrangement as claimed in claim 1, wherein the first driven lever is pivotally coupled by way of a first connecting joint to a first drive lever, wherein the second driven lever is pivotally coupled to a second drive lever by way of a second connecting joint, and wherein one of the two drive levers is coupled to the drive motor so as to be driven thereby.

5. Drive arrangement as claimed in claim 4, wherein the first drive lever is pivotable around a first lever pivot axis and wherein the first lever pivot axis of the first drive lever is located between opposite ends of the first drive lever.

6. Drive arrangement as claimed in claim 5, wherein the second drive lever is pivotable around a second lever pivot axis and wherein the second lever pivot axis is located between opposite ends of the second drive lever.

7. Drive arrangement as claimed in claim 6, wherein the first and second lever pivot axes are identical.

8. Drive arrangement as claimed in claim 6, wherein the first and second lever pivot axes are stationary.

9. Drive arrangement as claimed in claim 7, wherein the drive levers are arranged so as to execute opposite motions when the drive motor is actuated.

10. Drive arrangement as claimed in claim 4, wherein ends of the drive levers which face away from the respective driven lever are each equipped with an arc-shaped toothed segment which is aligned around the pivot axis of the drive levers, wherein one toothed segment has an external tooth system and the other toothed segment has an internal tooth system which faces this external tooth system, wherein the drive motor has a driving pinion which is rotatable around an axis of rotation and wherein a driving pinion of the drive motor is drivingly coupled to the toothed segments.

11. Drive arrangement as claimed in claim 4, wherein connecting joints between the first drive lever and the first driven lever and between the second drive lever and the second driven lever are guided in an arc-shaped guide rail which is aligned around a pivot axis of a pivot connection of the drive levers to each other.

12. Drive arrangement as claimed in claim 4, wherein the drive is a linear drive and ends of the drive levers which face away from the respective driven levers are coupled to the linear drive.

13. Drive arrangement as claimed in claim 4, wherein the second drive lever is eccentrically coupled to the first drive lever with respect to the pivot axis of the first drive lever and wherein the second connecting joint is guided between the second drive lever and the second driven lever in an arc-shaped guide rail.

14. Drive arrangement as claimed in claim 4, wherein an end of the first drive lever which faces away from the first driven lever is equipped with an arc-shaped toothed segment which is aligned around the pivot axis of the first drive lever, and wherein the drive motor has a driving pinion which drivingly engages the toothed segment.

15. Drive arrangement as claimed in claim 1, wherein the joint arrangement has a first joint for coupling to the first driven lever and a second joint for coupling to the second driven lever, and wherein the joints of the joint arrangement have a first and a second joint axis which are rigidly coupled to one another and are aligned perpendicular to one another.

16. Drive arrangement as claimed in claim 15, wherein the joints of the joint arrangement comprise, at least in part, a ball joint.

17. Drive arrangement as claimed in claim 4, wherein ends of the driven levers which face away from the drive levers are coupled to one another by way of a joint axis of a joint of the joint arrangement.

18. Drive arrangement as claimed in claim 4, wherein the connecting joints each have first and second joint axes which are rigidly coupled to one another and are aligned perpendicular to one another, each first joint axis being coupled to the respective driven lever and the second joint axis having a coupling to the respective drive lever.

19. Drive arrangement as claimed in claim 18, wherein the connecting joints comprise, at least in part, a ball joint.

20. Drive arrangement as claimed in claim 4, wherein at least one of the pivot axes of the drive levers is aligned essentially perpendicular to the hatch axis in the installed state.

21. Drive arrangement as claimed in claim 1, wherein the drive motor is configured for being located in an area of a rear roof frame of the body, in the installed state.

22. Drive arrangement as claimed in claim 1, wherein the joint arrangement, viewed in a transverse direction of the motor vehicle in the installed state, is configured for being located in a middle area of the vehicle near the hatch axis.

23. Hatch arrangement of a motor vehicle, comprising:

a hatch,

a motor vehicle body having a hatch opening, the hatch being pivotally coupled to the body for movement around a hatch axis for opening and closing the hatch opening, and

a drive arrangement for producing driving movement of the hatch between open and closed positions thereof, the drive arrangement having a drive with a drive motor and a transmission linkage connected to an output side of the drive motor,

wherein the transmission linkage has a first driven lever and a second driven lever for transmission of movement forces to the hatch, wherein the driven levers converge on a joint arrangement which is located on the hatch and are coupled to the joint arrangement by drive engineering, and wherein lines of dynamic effect of the two driven levers form an included angle with one another which corresponds to the respective position of the hatch.

24. Hatch arrangement as claimed in claim 23, wherein the first driven lever is pivotally coupled by way of a first connecting joint to a first drive lever and the second driven lever is pivotally coupled to a second drive lever by way of a second connecting joint, and wherein one of the two drive levers is coupled to the drive motor so as to be driven thereby.
