Definitions
- the invention relates to a method for regulating the inclination of at least one car body in a vehicle which comprises at least one car body, the inclination being effected by at least one tilt drive.
- the invention further relates to an apparatus for performing this method with at least one tilt drive for tilting at least one car body in a vehicle, which comprises at least one car body.
- a method according to the preamble of claim 1 and a device according to the preamble of claim 4 for carrying out the method according to claim 1 is known from WO 91/00815 AI.
- the requirement for avoiding torsion of the car body is taken into account by supplying the tilt drives designed as hydraulic actuators with hydraulic fluid from a common valve. This design measure is intended to ensure that the same forces act in the hydraulic actuators of both running gears. Because the transmission ratio of engine torques to wagon body torques is a non-linear function of the tilt angle, and because, due to the principle, a tilt angle difference of the order of magnitude of the difference in track excesses between the two trolleys occurs the car body torsional moment depending on this non-linearity and the inclination angle difference.
- the method and the device according to WO 91/00815 AI is not suitable for vehicles whose car bodies are inclined by electrically driven actuators.
- EP 0 557 893 A1 discloses a method in which the inclination angle between the two undercarriages and the car body is regulated to the same value by means of regulating devices and is set to this value by hydraulic actuators.
- the excitation from the track especially in transition arches, causes the car body to twist.
- this method it must be ensured that the torsion which is present anyway is not additionally increased inadmissibly by an asynchronism of the inclination angles on the two running gears.
- the object of the present invention is to provide a method and a device which keeps the torsion of the car body to a minimum even in car bodies which are inclined by electrically driven actuators, even under unfavorable operating conditions.
- a motor torque setpoint is specified for a predeterminable number of undercarriages of a vehicle with at least one electric tilt drive in such a way that the body torsion is minimal.
- the device according to the invention for carrying out the method according to claim 1 comprises at least one electric tilt drive for a predeterminable number of undercarriages of a vehicle, the electric tilt drive being able to be given a setpoint of engine torque in such a way that the body torsion is minimal.
- the method according to the invention and the device therefor are suitable both for road vehicles and for rail vehicles.
- the use of the method according to the invention or the device according to the invention should only be necessary in road vehicles in exceptional cases.
- the tilt drive is designed as an electrically driven actuator. Compared to a hydraulic actuator, such a tilt drive requires a significantly lower power requirement, since at the high pressure of the hydraulic system a large part of the hydraulic fluid is not converted into mechanical work, but as heat dissipation. Furthermore, the use of electrical actuators allows a more compact design overall, since there is no need for a voluminous hydraulic power supply. Together with the saving in installation volume in the vehicle, the weight of the tilt system is considerably reduced. Furthermore, the electric tilt drives are less noisy than hydraulic actuators, since there are no disturbing noises from the switching of hydraulic valves and from the pump with the associated drive unit. Furthermore, the solution according to the invention is characterized by less maintenance effort and greater environmental friendliness compared to a hydraulic system, since there are no disposal problems with regard to the hydraulic fluid when changing the oil or if the hydraulic system is damaged.
- the inclination-dependent non-linearity from engine torque to car body torque can be compensated for electronically in an advantageous manner. This possibility further reduces the difference in the car body torques exerted by the electric tilt drives on both chassis.
- 1 designates a tilt controller which, via its output, outputs a set body torque value MW * in parallel to a compensation device 2 and a compensation device 3.
- the compensation device 2 is assigned to the first undercarriage of the car and the compensation device 3 is assigned to the second undercarriage of this car.
- the transmission ratio from the motor torque MM ⁇ _ of the electric tilt drive on the first undercarriage to the body torque MW] _ on the first undercarriage is compensated, which is a non-linear function of the tilt angle ⁇ _ of the body over the first undercarriage.
- the transmission ratio from the motor torque M 2 of the electric tilt drive on the second chassis to the car body torque MW2 on the second chassis is compensated in the compensation device 3, the one is non-linear function of the tilt angle 72 of the car body relative to the second chassis.
- the motor torque setpoint MM * ⁇ orMM * 2 for the electrical tilt drive is then applied to the first or second undercarriage.
- the motor torque setpoint MM * ⁇ or MM * 2 is then given to a torque control loop 4 or 5 (closed control loop for the engine torque).
- the torque control circuit 4 or 5 regulates the mechanical drive power of the motor, which outputs a motor torque MM ⁇ _ orMM2 to a tilting system 6 or 7.
- the tilting system 6 tilts the car body relative to the first undercarriage
- the tilting system 7 tilts the car body over the second undercarriage.
- both tilting systems 6 and 7 each include an actuator and a four-bar linkage (joint between the car body and the pendulum carrier, which is suspended on a chassis). Due to the motor torque M ⁇ or MM2 applied by the electric drive, a tilt body torque MW ⁇ or MW2 is applied by the tilting system 6 or 7 via the four-bar linkage of the relevant chassis.
