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. An 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 an electric motor (31) and at least one brake-shoe element (17) that can be moved relative to the brake rod (6) via the electric motor (31), 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) which controls 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),

an actuation element (23) having an axis of rotation,

wherein the electric motor directly or indirectly drives the actuation element (23) in rotation to create the relative motion between the brake-shoe element (17) and the brake rod (6),

wherein the actuation element is equipped with at least one actuation cam (25) that acts on the at least one brake-shoe element (17),

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

wherein the at least one actuation cam (25) is located on an end face of the actuation element (23) that faces the brake-shoe element (17),

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.

2. The arresting system (1) in accordance with claim 1,

wherein between the actuation element (23) and the at least one brake-shoe element (17), there is a transfer plate (19) that can move up and down inside the housing (10);

wherein on a first end face of the transfer plate facing 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, and

wherein the transfer plate (19) has, on its opposing second end face, one receiving recess (18) for the at least one brake-shoe element (17).

3. The arresting system (1) in accordance with claim 1, further comprising a second brake shoe element permanently attached to the housing opposite the at least one brake shoe element, so that the brake rod is between the brake shoe elements.

4. The arresting system (1) in accordance with claim 1, wherein the at least one sensor (8) detects a speed and/or acceleration of a swivel motion between the two swivel-mounted elements.

5. The 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).

6. The arresting system (1) in accordance with claim 5, wherein at least one additional sensor is provided that detects objects and/or movements outside of the vehicle (2) in the area of the vehicle door (3).

7. The arresting system (1) in accordance with claim 6, wherein the at least one additional sensor is arranged on the outside of the vehicle door (3) or on the end face of the vehicle door (3).

8. The arresting system in accordance with claim 5, wherein 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.

9. The arresting system (1) in accordance with claim 8, 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).

10. The arresting system (1) in accordance with claim 5, wherein 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.

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

12. The arresting system (1) in accordance with claim 6, wherein the at least one additional sensor includes a first sensor arranged on the outside of the vehicle door (3) and a second sensor arranged on the end face of the vehicle door (3).

13. An 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 an electric motor (31) and at least one brake-shoe element (17) that can be moved relative to the brake rod (6) via the electric motor (31), 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) which controls 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 the electric motor (31) that directly or indirectly drives an actuation element (23) in rotation to create the relative motion between the brake-shoe element (17) and the brake rod (6),

wherein the actuation element is equipped with at least one actuation cam (25) that acts on the at least one brake-shoe element (17),

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 the at least one actuation cam (25) is provided on the outer periphery of the actuation element (23) and is shaped like a spiral.
