Definitions

  • the invention relates to a drive for rail vehicles in which there is a transverse spring travel between the body of the rail vehicle and the wheels or wheelsets of the drive.
  • transverse spring travel is necessary in order to achieve a decoupling between the wheels or wheel sets of the drive and the car body.
  • This decoupling is necessary in order to ensure a high level of running comfort and to avoid undesirable cross bumps in the car body.
  • Decouplings with linear or progressively increasing transverse characteristic curves and linear or progressive or linear and then progressive transverse characteristic curves are known.
  • the transverse path between the body and the wheels or wheelsets is limited by the requirement for the largest possible passenger compartment or wagon cross-section on the one hand and the boundary profile available for rail vehicles on the other.
  • a disadvantage of this cross-decoupling described above is that, when traveling through bends, the car body is in the region of the progressive transverse characteristic even with a slight excess of centrifugal force. Since the excess centrifugal force acts continuously when traveling through bends, a new quasi-static equilibrium state results for this state. Due to track position errors, the vehicle is still subjected to shocks in this new state of equilibrium. These shocks are transmitted through the higher transverse rigidity of this state of equilibrium (progressiveness of the transverse buffer) with a hard coupling between the body and wheels or wheelsets in the body.
  • the aim of the invention was to find a decoupling between the body and wheels or wheelsets, which not only acts in the straight line, but also when traveling under bends with excess centrifugal force, so that the decoupling in the bend corresponds almost to that in the straight line.
  • this object is achieved in that the car body and wheels or wheel sets are connected to one another directly or with the interposition of components of the drive by an actuating element that keeps the car body resiliently close to the central position with excess centrifugal force.
  • the spring force of the control element is controlled by a displacement and / or force sensor measuring the relative movement between the body and wheels or wheel sets and a control circuit connected downstream of the latter.
  • the actuating element can be acted upon hydraulically, pneumatically or by an electric motor.
  • the control can also achieve a low transverse stiffness in the respective state of equilibrium.
  • the car body (9) is mounted with the cradle cross member (6) so that it can move transversely via the air spring (7) on the drive frame (1).
  • An air cylinder (12) is articulated inside each of the side long beams (3) of the drive frame (1) and is likewise articulated on the cradle cross member (6) with its piston rod (13).
  • the air cylinders (12) are double-acting. Both working chambers (piston chamber (14) and annulus (15)) of each air cylinder (12) are connected by air lines (16), the piston chamber (14) of one air cylinder (12) each with the annulus (15) of the other air cylinder (12) through the air lines (16) is connected.
  • the air lines (16) are in turn connected to an air tank (17) which is filled by a compressed air generator (19).
  • a pressure relief valve (18) downstream of the air tank (17) and an air volume regulator (20) generally regulate the air supply to the control elements (22).
  • Each air cylinder (12) is equipped with a travel meter (21), via which control elements (22) interposed in the air lines (16) regulate the air supply or air extraction of the air cylinders (12).
  • each working chamber (piston chamber (14), annular chamber (15)) of each air cylinder (12) is acted upon with the same high air pressure.
  • all working spaces (piston space (14), annular space (15)) of the air cylinders (12) are continuously connected to one another via the air lines (16).
  • the pressurized air quantities of both air cylinders (12) can be exchanged without restoring forces.
  • the odometer (21) of the air cylinder (12) measures the transverse path and passes this information on to the controls (22).
  • the resulting reduction in pressure in the unloaded work spaces (piston chamber (14) or annular space (15)) of the two air cylinders (12) means that the air cushion blocked in the loaded work spaces is fully effective.
  • the transverse force is intercepted and the car body (9) with the cradle cross member (6) is returned approximately in the middle position.
  • the starting situation is restored via the corresponding information from the odometer (21) to the control elements (22).
  • the odometer (21) and the control elements (22) are expediently designed or set so that small cross paths of the car body (9) with the cradle cross member (6), for. B. with sinusoidal movement in the straight line and with track position errors in the straight line, the controls do not respond.
  • control elements are regulated by means of appropriate electronics in such a way that any desired characteristic of the transverse decoupling is achieved.
  • the arrangement of the invention is not limited to the example described in the embodiment. It can advantageously also be arranged directly between the car body and the wheels or wheel sets, if appropriate with the interposition of suitable components at another point.
