Definitions
- the invention relates to a method for measuring a track curvature in a running gear for rail vehicles, and a method for steering alignment of an axis of a rail running gear rotatably fastened to a running gear frame after the curvature of the track.
- Rail vehicles with two-axle chassis are mainly used in local transport. Tight bends, which are often determined by the course of the road, lead to poor cornering of multi-axle chassis. This can be observed primarily in rail vehicles whose wheels are rigidly connected to the chassis frame with regard to their yawing movement.
- axle or the wheels are mounted in a steerable manner in the chassis frame.
- a steering movement can take place in accordance with the curvature of the track.
- a method for curve detection is known from DE 92 1 9 042 U1, which determines the curvature of the track by means of inductive sensors.
- methods are known in which the steering of the wheels or axles takes place passively. This can be done either by the guidance forces or by mechanically coupling the axle position with the angle of rotation between the car bodies.
- these mechanical solutions have the disadvantage that they only allow very imprecise steering.
- the object of the present invention is to provide a method for measuring the curvature of the track for rail vehicles in order to use this value to calculate the target value for the steering angle control.
- Figure 1 shows the ratio of the translation and yaw rate depending on the curvature of the rail.
- Figures 1 and 2 show a chassis 10 for a rail vehicle, not shown, with axles 1 2 and 1 3, to which wheels 1 6 are attached.
- the axes 1 2 and 13 are fixed in the chassis 10.
- the chassis 10 or the axles 12 and 13 are rotatably supported by a centrally arranged joint 15.
- the undercarriage 10 is shown as it travels through a curved track 11 with a translation speed v and has a radius R.
- the radius R or the curvature of the track le can be calculated with the aid of means which determine the yaw rate ⁇ .
- the track curvature ⁇ corresponds to the reciprocal of the radius R.
- the division of the yaw rate ⁇ by the translation speed v results in the track curvature ⁇ , in accordance with the equation shown in FIG.
- the value of the track curvature hier obtained from this is used to steer the axes 1 2 or 13.
- the relationship between the real and calculated track curvature ⁇ can be seen in FIG. 3.
- the yaw rate ⁇ is preferably determined by a rotation rate or gyro sensor, not shown, as is known, for example, from navigation technology.
- the position of the axle in the track channel can shift laterally by a few millimeters. Power surges, which act on the running gear 10 because of the often inaccurate track guidance, can lead to the yaw movement. However, these oscillating movements have a not insignificant influence on the measured values of the gyro sensor.
- the measured value of the yaw rate ⁇ is smoothed by means of a low-pass filter (not shown). The effect of the low-pass filter when driving through a track curve can be seen in FIG. 5.
- the track curvature ⁇ is used to determine the desired steering angle ⁇ soii according to which the axes 1 2 and 13 are corrected.
- the setting of axes 1 2 and 1 3 can e.g. done by a servo motor.
- the sine of the desired steering angle ⁇ soii of the control system (not shown) is calculated by multiplying the curvature of the track ⁇ by half the distance b between the axes 1 2 and 13, according to the equation in FIG. 2.
- the first approximation states that for an exact setpoint calculation when entering a curve, both the
- Curvature course on the front axle 1 2 as well as on the rear axle 13 should be known, but only one value in between is measured due to the chassis rotation, as shown in FIG. 3.
- there is an approximation in the steering angle calculation while entering the curve since the geometric relationship according to FIG. 2 is only exactly correct if both axes 1 2 and 1 3 are in the curve.
- the two approximations essentially cancel each other out, so that the calculated one Setpoint value ⁇ soii, as shown in FIG. 4, corresponds very well with the ideal steering angle ⁇ . If a rail vehicle has a plurality of running gears 10, then only the target steering angle ⁇ soii i for the foremost running gear in the direction of travel has to be determined.
- the other trolleys can take over this target steering angle at different times.
- the target steering angle ⁇ soii 1 + 1 for the undercarriages following in the direction of travel are calculated by time delays ⁇ t from the first target steering angle ⁇ soii i.
- the delay ⁇ t results from dividing the distance ai of the trailing chassis i from the first chassis by the translation speed v.
