Abstract

Disclosed is an arresting system for arresting a swivel motion between two swivel-mounted elements, including a brake rod connected to the first element, an arresting device on the second element with a housing, through which the brake rod extends, in which case the arresting device has a drive and at least one brake-shoe element that can be moved via the drive relative to the brake rod. The brake-shoe element is inside the housing and engageable with the brake rod upon exertion of a braking force. Included are a sensor, and an electronic device controlling braking force exerted by the brake-shoe element on the brake rod depending on the signals from the sensor. The drive is an electric motor driving in rotation an actuation element that, to produce the relative motion between the brake-shoe element and the brake rod, has an actuation cam acting on the brake-shoe element.

Claims

1. Arresting system (1) for arresting a swivel motion between two swivel-mounted elements (3, 4), comprising:

a brake rod (6) that is connected to the first element (4),

an arresting device (7) that is arranged on the second element (3), with a housing (10), through which the brake rod (6) extends, where the arresting device (7) has a drive and at least one brake-shoe element (17) that can be moved relative to the brake rod (6) via the drive, where said brake-shoe element is arranged inside the housing (10) and can be engaged with the brake rod (6) when a braking force is exerted;

at least one sensor (8), and

an electronic control device (9) for controlling the level of the braking force exerted on the brake rod (6) by the at least one brake-shoe element (17) depending on the signals from the at least one sensor (8),

wherein drives an actuation element (23) in rotation;

here, to create the relative motion between the brake-shoe element (17) and the brake rod (6), the actuation element is equipped with at least one actuation cam (25) that acts directly or indirectly on the at least one brake-shoe element (17).

2. Arresting system (1) in accordance with claim 1, wherein the axis of rotation of the actuation element (23) is aligned with or is parallel to the direction of motion of the brake-shoe element (17), and that the at least one actuation cam (25) is located on an end face of the actuation element (23) that points in the direction of the brake-shoe element (17).

3. Arresting system (1) in accordance with claim 2, wherein the at least one actuation cam (25) is designed as a spiral that extends around the axis of rotation of the actuation element (23), where said spiral rotates around the axis of rotation.

4. Arresting system (1) in accordance with claim 3, wherein between the actuation element (23) and the at least one brake-shoe element (17), there is a transfer plate (19) that is torque-proof and that can move up and down inside the housing (10);

here, on its end face pointing toward the actuation element (23), said transfer plate is equipped with at least one spiral (21) that corresponds to the at least one actuation cam (25) of the actuation element (23) and is engaged in said actuation element, where the transfer plate (19) has, on its opposing end face, preferably one receiving recess (18) for the at least one brake-shoe element (17).

5. Arresting system (1) in accordance with claim 1, wherein the axis of rotation of the actuation element (23) runs transversely to the direction of motion of the at least one brake-shoe element (17) and that the at least one actuation cam (25) is provided on the outer periphery of the actuation element (23) and in particular is shaped like a spiral.

6. Arresting system (1) in accordance with claim 1, wherein at least one spring element is provided, which prestresses the at least one brake-shoe element (17) in a direction away from the brake rod (6).

7. Arresting system (1) in accordance with claim 1, wherein, opposite the at least one brake-shoe element (17), there is another brake-shoe element (17) permanently attached to the housing (10) in such a way that the brake-shoe elements (17) accommodate the brake rod (6) between them.

8. Arresting system (1) in accordance with claim 1, wherein the at least one sensor (8) is designed in such a way that it picks up the speed and/or acceleration of a swivel motion between the two swivel-mounted elements.

9. Arresting system (1) in accordance with claim 1, wherein the two swivel-mounted elements are a vehicle frame (4) and a vehicle door (3) of a vehicle (2).

10. Arresting system (1) in accordance with claim 9, wherein at least one additional sensor is provided that is designed in such a way that it picks up objects and/or movements outside of the vehicle (2) in the area of the vehicle door (3), in which case the at least one additional sensor can be one part of an already existing vehicle monitoring system.

11. Arresting system (1) in accordance with claim 10, wherein the at least one additional sensor is arranged on the outside of the vehicle door (3) and/or on the end face of the vehicle door (3).

12. Arresting system in accordance with claim 9, wherein the arresting device (7) and the electronic control device (9) are designed and set up in such a way that the arresting device (7) does not exert any braking force on the brake rod (6) when the vehicle door (3) is in the closed state.

13. Arresting system (1) in accordance with claim 12, wherein a closed-state sensor is provided that indicates the closed state of the vehicle door (3) and that sends its signals to the control device (9).

14. Arresting system (1) in accordance with claim 9, wherein the control device (9) is set up in such a way that, as soon as the vehicle door (3) is opened from its closed state, the braking force exerted by the at least one brake-shoe element (17) on the brake rod (6) is raised to a preset constant braking force.

15. The arresting system of claim 3, wherein said spiral rotates around the axis of rotation once.

16. The arresting system of claim 5, wherein the axis of rotation of the actuation element (23) runs both transversely and vertically to the direction of motion of the at least one brake-shoe element.

17. The arresting system of claim 6, wherein the at least one spring element is a cup spring.

18. Arresting system (1) in accordance with claim 2, wherein at least one spring element is provided, which prestresses the at least one brake-shoe element (17) in a direction away from the brake rod (6).

19. Arresting system (1) in accordance with claim 3, wherein at least one spring element is provided, which prestresses the at least one brake-shoe element (17) in a direction away from the brake rod (6).

20. Arresting system (1) in accordance with claim 4, wherein at least one spring element is provided, which prestresses the at least one brake-shoe element (17) in a direction away from the brake rod (6).
