Definitions

  • the invention relates to a stabilizing and straightening drive for a turret of a vehicle, which is rotatably mounted on the vehicle body via a turntable and on the friction surfaces driven in opposite directions and pressurized friction pads actuating torques for aligning the turret to a desired direction can be applied.
  • a turret is part of a turret weapon system on an armored vehicle.
  • the torque to be applied by the stabilization and directional drive of such a tower weapon system depends on the required acceleration torque to overcome the inertia of the turret and on the maximum unbalance moments that occur. Imbalance moments must be absorbed in the azimuth by the stabilizing and straightening drive, for example, when the vehicle equipped with the turret is in an inclined position or driving or when the center of gravity of the turret does not coincide with the axis of rotation and is linearly accelerated due to cornering, pitching and rolling movements.
  • Stabilizing and directional drives of the type described in the introduction have been proposed (DE-PS 22 17 684, DE-PS 27 27 582).
  • a drive torque is transmitted from a pinion to the turntable of the turret by the drive arranged inside the turntable.
  • These Ar t of the force introduction has two major drawbacks: the amount of transmittable torque is limited by the tooth strength.
  • the introduction of torque on the rotating assembly is dynamic "soft", so that the control performance of the rehturmes via a regulator to set the direction of the D-regulated drive is reduced. Normally, the torques of the turret occurring due to the unbalance are within the limits that can be applied by the known drives.
  • the invention has for its object to provide a stabilizing and straightening drive, with which large unbalance moments characteristic of such turrets can be absorbed, the control quality being to be increased.
  • the braking surfaces are formed on two concentrically arranged rotating rings adjacent to the middle turntable radius, which are mounted on the vehicle body or on the turret and driven in opposite directions, and that the friction linings are arranged on the same mean radius as the rotating rings, axially adjacent to the rotating tower or on the vehicle body.
  • the frictional force generated on the rotating rings with the stabilizing and straightening drive according to the invention brings about a direct application of a stabilizing or straightening torque which counteracts the unbalanced moments. This moment is multi due to the frictional force given with the large lever arm between the rotating rings and the center of the turret.
  • the dynamic eigenvalues of the slewing ring bearing and the otherwise usual gear stage are eliminated.
  • the pressing force is applied with the help of a controller, which aligns the turret in a given target direction (straightening) or keeps the turret aligned in this direction regardless of movements of the base (stabilization).
  • a controller which aligns the turret in a given target direction (straightening) or keeps the turret aligned in this direction regardless of movements of the base (stabilization).
  • the structure and mode of operation of this controller have already been described earlier (DE-PS 22 17 684) and are not described again in this application.
  • control loops with interference feedforward control as are customary for controlled systems with strong interference, can also be used with the invention.
  • the linear acceleration acting at the center of gravity is measured and applied to the control loop.
  • the drive according to the invention also works with a large servo ratio. In other words, the power required to regulate the pressing force is much lower than the power required to straighten the turret.
  • the unregulated primary power is preferably made available by means of at least one drive group, which is preferably arranged on the vehicle body and has, for example, an electric motor.
  • the friction linings are advantageously pressed electromagnetically onto the braking surfaces of the rotating rings by means of magnetic force, the electrical power to be fed into the rotating tower via a slip ring being far less than the primary power.
  • the stabilizing and straightening drive can be designed for very high maximum torques.
  • the magnetic force for pressing the friction linings can also be applied by means of permanent magnets which counteract the electromagnets.
  • the permanent magnets block the braking surfaces, i. H. to lock or "lash" the turret towards the vehicle body in a very simple manner.
  • an additional toothing can be arranged on one of the rotating rings to interact with a hand-operated pinion.
  • 1 denotes a vehicle body and 2 denotes a turret with barrel weapon 3 and turntable 4, by means of which the turret 2 can be rotated relative to the vehicle body 1.
  • an electric motor 20 is drawn with dashed lines, which acts on two gears 21, 22.
  • An output pinion 23, 24 belongs to each transmission.
  • the rotating rings are thus driven in opposite directions via the two pinions 23, 24, but driven at the same speed.
  • the tooth forces are kept comparatively low due to the use of two pinions.
  • a corresponding drive 20 can in turn be provided with two output pinions 23, 24, as indicated in FIG. 1.
  • Part of the housings 16, 17 can contain permanent magnets (not shown), which result in a permanent attractive force between the friction linings 12, 13 and the braking surfaces 10, 11.
  • the electromagnets 14, 15 counteract the permanent magnets in a controlled manner during operation. The counteraction of the Electromagnets 14, 15 are lifted so that a non-positive locking or lashing between the turret 2 and the vehicle body 1 is generated by the permanent magnetic force.
  • the electromagnets 14, 15 are energized by a controller (not shown) which, in the event of an angular deviation of the rotary position of the turret 2 or of the barrel weapon 3 from a predetermined desired direction, emits actuation signals in the sense of canceling the angular deviation either to the electromagnets 14 or to the electromagnets 15.
  • a controller not shown
  • the associated rotating ring 6 or 7 is braked, as a result of which a drive torque is applied to the rotating tower practically without delay, which varies depending on the size of the control pulse, but because of the large distance between the electromagnets 14, 15 and the center of the rotating ring M (FIG. 1) and any large selectable friction lining area of the friction linings 12, 13 can always be made larger than the largest unbalance moments of the turret occurring in practice.
