Definitions

  • the invention relates to a hydraulic straightening system in which at least one straightenable mass, such as the turret or weapon of an armored vehicle, is directed in accordance with a command signal.
  • Such straightening systems have hitherto generally included hydroconstant motors for a side-straightening mass as a tower and large-volume hydraulic cylinders for a height-straightening mass as a weapon, the straightening process being controlled by fast servo valves to which hydraulic energy from hydropumps and storage tanks is available. These are kept in a certain pressure range by intermittently working filling pumps.
  • a straightening system is known from DE-A-35 36 858, in which the directional mass is controlled with the aid of a servo valve.
  • the servo valve is equipped with an on-off valve and installed in a hydraulic supply line.
  • a force control circuit and a stabilization circuit are hydraulically coupled via the servo valve.
  • the servo valve is functionally assigned to the force control circuit or the stabilization circuit by means of electronic control. With the help of the servo valve becomes a hydraulic cylinder controlled, which carries out the height control of the straightenable mass.
  • a hydraulic straightening system according to the preamble of claim 1 is known, in which a hydraulic motor is supplied by pumps with hydraulic fluid.
  • a drive pump running at constant speed and a secondary pump are provided.
  • the aiming system of guns can be controlled with the help of the hydraulic motor.
  • the object of the present invention is to improve a hydraulic straightening system of the type mentioned in the introduction in order to avoid the use of large-volume pressure accumulators.
  • This object is achieved in that the mass to be straightened is driven by at least one hydraulic adjustment motor, at least two pressure sensors influencing the guide signal being provided, which detect the pressure in front of and behind the hydraulic adjustment motor.
  • the dynamics of the straightening system is additionally improved in that at least two pressure sensors influencing the command signal are provided which detect the pressures prevailing in front of and behind the hydraulic adjustment motor. This avoids cavitation on the suction side and a drop in pressure on the pressure side below a still permissible minimum level. It is particularly advantageous to link the vertical and lateral directional circles so that the oil requirement and excess oil between the two circles have a compensating effect can. This is particularly easy when both adjustment motors are hydraulically connected in parallel. In this case, it is sufficient to use only two pressure sensors in total. The compensation between height and lateral directional circle comes about automatically.
  • the hydraulic consumers are supplied by a pressure regulating pump which is driven directly by a vehicle engine or an additional energy supply system.
  • a pressure regulating pump which is driven directly by a vehicle engine or an additional energy supply system.
  • the pump can be swiveled into a zero stroke and consumes practically no hydraulic energy as long as no directional movements have to be carried out. This is especially true if the pressure setpoint is set low at the same time.
  • a reversing pump is used as the hydraulic pump. This is able to partially convert the braking energy generated in the straightening system back into mechanical energy and feed it back to the engine.
  • a further embodiment of the invention consists in that the actuator is designed for a mass that can only be directed within a limited angular range as a threaded spindle with a spindle nut and the spindle nut or the threaded spindle is driven by a hydraulic adjusting motor.
  • This solution has the advantage that the streakiness of the leveling drive increases considerably compared to a hydraulic cylinder and thus disturbing natural vibrations of the height-adjustable mass significantly impair the directional behavior.
  • releasable releasable brakes are arranged parallel to the hydraulic adjustment motors in the event of pressure loss on the motors.
  • the brakes are used to automatically lock the straightening system if the hydraulic motors' oil pressure is too low.
  • they can absorb braking energy in addition to switching the hydraulic motors into pump mode.
  • the directional mass (1) is driven by a hydraulic adjustment motor (3) via a directional gear (2).
  • the height-adjustable mass (4) is also driven by a hydraulic adjustment motor (6) via a gear (5).
  • the gear (5) is, for example, a spindle drive according to FIG. 4.
  • the directionally adjustable mass (1) is in this Case designed as a tower and the height-adjustable mass (4) as a weapon of an armored vehicle.
  • the hydraulic adjustment motors (3, 6) are connected to a hydraulic system via a pressure line (7) and a tank line (8).
  • the hydraulic adjustment motors (3,6) can be controlled in both directions of rotation and can be continuously adjusted between the respective maximum speeds.
  • the adjustment signal is formed by a command signal (9, 10) in comparison to an actual signal (11, 12).
  • the command signal comes from fire control electronics, not shown.
  • the hydraulic adjustment motor (3) is operated so that the pressure in the tank line (8) also does not fall below a certain minimum pressure.
  • the formation of cavitation must be prevented, in which gas accumulations form in the area of the hydraulic fluid.
  • the pressure signal from the sensor (13) leads to a limitation of an acceleration phase
  • the pressure signal from the sensor (14) leads to a limitation of a deceleration phase.
  • FIG. 3 shows the entire straightening system of a device designed as an armored vehicle.
  • the supply of the straightening system is shown by an engine (15) which drives a hydraulic pump (16).
  • This can be a pump with a constant delivery volume or, as shown, a pump with a variable delivery volume.
  • the pump sucks hydraulic fluid from a tank (17), which is preferably designed to be closed and optionally provided with a slight pre-pressure.
  • a tank (17) which is preferably designed to be closed and optionally provided with a slight pre-pressure.
  • This shows that the hydraulic system of the straightening system does not contain any accumulators or cylinders which absorb or release larger quantities of oil. So that the volume of the tank (17) can be kept small.
  • the amount of oil in the circuit is constant at almost every moment.
  • the pressure control device is also used to switch the pressure control pump (16) to unpressurized circulation when the armored vehicle is driven with the weapon system lashed.
  • the lashing can cause brakes (19, 20) on the gear trains between the hydraulic adjustment motors (3,6) and the straightenable masses (1,4).
  • These brakes (19, 20) are controlled by switching valves (21, 22) in such a way that they are closed in the depressurized state and are opened when the pressure in the line (7) is applied.
  • the pressure sensors (23, 24) are arranged in the lines (7, 8) so that they jointly monitor the pressure level for both hydraulic adjustment motors (3, 6).
  • the entire straightening system is controlled by a control device (25) which processes the height and side of the fire control signals (26) together with the system-internal signals such as the straightening signals (27,28) and the pressure sensor signals (29,30) and control signals (31,32 ) for the hydraulic adjustment motors (3,6) provides a control signal (33) for the pressure regulating hydraulic pump (16) and control signals (34,35) for the switching valves (21,22) which control the brakes.
  • a height adjustment drive with a weapon (36) for an armored vehicle is shown, on the weapon lock (37) of which a threaded spindle (38) is articulated via a joint (39).
  • a spindle nut (40) is mounted in a gear box (41), which in turn is mounted in the tower with a joint (42). If the spindle nut (40) is rotated, it causes a change in the distance between the joints (39, 42) and acts like a height adjustment cylinder.
  • the spindle nut (40) itself is driven by a hydraulic adjustment motor (44) via gearwheels (43) in the gearbox (41).
  • a brake (45) on the gearbox (41) which has the task of locking the weapon in a rest position or of supporting the braking action of the hydraulic adjustment motor in the event of deceleration from a directional movement.
