Abstract

A device for positioning and position stabilizing an inert mass supported for sluing on a base, comprising two driven portions (11,15) adapted to be driven by a motor (1) by way of controllable friction clutches (9,13) is furnished with a single rotor (5) driven by the motor (1) and cooperating with the two friction clutches to transmit a coupling torque in the same sense of rotation. Each driven portion (11,15) acts through separate power transmissions each (16-18,20-23) on the mass, one of the power transmissions effecting a reversal of the direction of rotation.

Claims

1. A device for positioning and position stabilizing an inert mass, such as a barrelled weapon supported for sluing on a base, such as a vehicle body, comprising two driven portions adapted to be driven by one motor by way of a rotor each and a controllable friction clutch each so as to slue the mass selectively in one of its two sluing directions into a predetermined pivot position, characterized in that only a single rotor (5) is provided, in that the two friction clutches (9,13) are so arranged with respect to the rotor (5) that the rotor transmits equidirectional torques to the driven portions (11,15) of both friction clutches, and in that the driven portions (11,15) of the two friction clutches act on the inert mass by a separate power transmission each (16-18,20-23) one of which effects reversal of the direction of rotation.

2. The device as claimed in claim 1, characterized in that the friction clutches (9,13), the rotor (5), and, if desired, the inert mass have axes of rotation which are aligned.

3. The device as claimed in claim 1, characterized in that the power transmissions (16-18,20-23) are gearings acting with their output pinions (18,23) on a ring gear (24) and one of them comprising an additional intermediate gear (21).

4. The device as claimed in claim 1, characterized in that two receivers (25,26)are provided to detect the motor speed and the rotational speed at the mass end of the driven side of the friction clutches (9,13), and in that the motor speed is adapted to the mass end rotational speed by means of a motor speed control circuit.

5. The device as claimed in claim 4, characterized in that the motor speed is raised by subsequent feeding of current when the mass end rotational speed of the friction clutch rises.

6. The device as claimed in claim 4, characterized in that the motor speed is raised by subsequent feeding of current upon application of an aiming manipulator signal.

11. The device as claimed in claim 1, characterized in that a structural group is connected with the inert mass and consists of a locking brake (36) to block the mass against sluing movement and an auxiliary drive means (41) to slue the mass, particularly by hand when the motor (1) is at standstill.

12. The device as claimed in claim 11, characterized in that the structural group comprises a planetary gearing, the hollow wheel (30) of which is operatively connected to the mass, the web (32) of which cooperates with the locking brake (36) acting against the base (disc 38), and the sun wheel (33) of which is adapted to be coupled with the auxiliary drive means (41) by a spring brake (44) adapted to be lifted mechanically.

13. The device as claimed in claim 12, characterized in that the hollow wheel (30) is operatively connected with the mass by way of one of the two power transmissions (16-18,20-23).

14. The device as claimed in claim 4, characterized in that a structural group is connected with the mass and consists of a locking brake (36) to block the mass against sluing and an auxiliary drive means (41) to slue the mass, particularly by hand when the motor (1) is at standstill.

15. The device as claimed in claim 14, characterized in that the structural group comprises a planetary gearing, the hollow wheel (30) of which is operatively connected to the mass, the web (32) of which cooperates with the locking brake (36) acting against the base (disc 38), and the sun wheel (33) of which is adapted to be coupled with the auxiliary drive means (41) by a spring brake (44) adapted to be lifted mechanically.

16. The device as claimed in claim 15, characterized in that the hollow wheel (30) is operatively connected with the mass by one of the two power transmissions (16-18,20-23).

7. A device for positioning and position stabilizing an inert mass, such as a barrelled weapon supported for sluing on a base, such as a vehicle body, comprising two driven portions adapted to be driven by one motor by way of a rotor each and a controllable friction clutch each so as to slue the mass selectively in one of its two sluing directions into a predetermined pivot position, characterized in that two receivers (25,26) are provided to detect the motor speed and the rotational speed at the mass end of the driven side of the friction clutches (9,13), and in that the motor speed is adapted to the mass end rotational speed by means of a motor speed control circuit.

8. The device as claimed in claim 7, characterized in that the motor speed is raised by subsequent feeding of current when the mass end rotational speed of the friction clutch rises.

9. The device as claimed in claim 7, characterized in that the motor speed is raised by subsequent feeding of current upon application of an aiming manipulator signal (63).

10. The device as claimed in claim 7, with which the friction clutches are controllable by a position or speed controller, characterized in that the reference input value for the position or speed controller (56) is limited for the subsequent feeding of current and thus the raising of the motor speed by application of an aiming manipulator signal (63) to the motor speed control circuit.

17. A device for positioning and position stabilizing an inert mass, such as a barrelled weapon supported for sluing on a base, such as a vehicle body, comprising two driven portions adapted to be driven by one motor by way of a rotor each and a controllable friction clutch each so as to slue the mass selectively in one of its two sluing directions into a predetermined pivot position, characterized in that a structural group is connected with the mass and consists of a locking brake (36) to block the mass against sluing and an auxiliary drive means (41) to slue the mass, particularly by hand when the motor (1) is at standstill, and in that the structural group comprises a planetary gearing, the hollow wheel (30) of which is operatively connected to the mass, the web (32) of which cooperates with the locking brake (36) acting against the base (disc 38), and the sun wheel (33) of which is adapted to be coupled with the auxiliary drive means (41) by a mechanically liftable spring brake (44).

18. The device as claimed in claim 17, characterized in that the hollow wheel (30) is operatively connected with the mass by one of the two power transmissions (16-18, 20-23).
