Abstract
A drive device for a hatch, in particular for a tailgate, comprising a cable, which is connected at one end to a cable pulley, which is configured to wind or unwind the cable according to the direction of rotation of the cable pulley, wherein the cable pulley is connected to a first superordinate assembly, such as a vehicle body, and which is connected at its other end to a second superordinate assembly, such as the hatch, which is pivotably attached relative to the first superordinate assembly, comprising an actuator, which is configured to drive the cable pulley, wherein the drive device furthermore comprises at least one deflection unit which has a deflection roll over which the cable runs between the cable pulley and the hatch.
Claims20
A drive device for a hatch, comprising:
- a cable comprising two interconnected sections, wherein a first of the two interconnected sections comprises a sling cable and a second of the two interconnection sections comprises a pull cable;
- a cable pulley connected to a first superordinate assembly and to the cable, wherein the cable pulley is configured to wind or unwind the cable according to a direction of rotation of the cable pulley, wherein the cable is further connected to a second superordinate assembly pivotably attached relative to the first superordinate assembly;
- an actuator configured to drive the cable pulley;
- at least one deflection unit which has a deflection roll over which the cable runs between the cable pulley and the second superordinate assembly;
- wherein a first end of the sling cable is connected to the second superordinate assembly and a second end of the sling cable is connected by way of a cable coupling to a first end of the pull cable, and wherein a second end of the pull cable is connected to the cable pulley;
- wherein the sling cable is sized in such a way that the sling cable is tensioned when an angle between the second superordinate assembly and the first superordinate assembly is substantially one hundred eighty degrees;
- and
- wherein the pull cable is sized such that the cable coupling cannot be wound into the cable pulley.
A hatch arrangement, comprising:
- a vehicle body;
- a hatch connected to the vehicle body with articulation, wherein the vehicle body comprises a portion to be closed off by the hatch;
- and
- a drive device comprising:
- a cable having two interconnected sections, wherein a first of the two interconnected sections comprises a sling cable and a second of the two interconnection sections comprises a pull cable;
- a cable pulley connected to the vehicle body and to the cable, wherein the cable pulley is configured to wind or unwind the cable according to a direction of rotation of the cable pulley, wherein the cable is further connected to the hatch;
- an actuator configured to drive the cable pulley;
- at least one deflection unit which has a deflection roll over which the cable runs between the cable pulley and the hatch;
- wherein a first end of the sling cable is connected to the hatch and a second end of the sling cable is connected by way of a cable coupling to a first end of the pull cable, and wherein a second end of the pull cable is connected to the cable pulley;
- wherein the sling cable is sized in such a way that the sling cable is tensioned when an angle between the hatch and the vehicle body is substantially one hundred eighty degrees;
- and
- wherein the pull cable is sized such that the cable coupling cannot be wound into the cable pulley.
