Definitions
- the present invention relates to a transverse tilting device between car body and chassis of a rail vehicle, where the support between the body and chassis over inclined cross beams with support surfaces of predetermined geometry and rollers, whose axes of rotation are aligned in the longitudinal direction of the vehicle are done and one between the body and chassis Acting actuator is provided to the car body relative to the chassis by a relative movement (Lateral movement with a rotary component) between the tilting cross beams and the rollers controlled about its longitudinal axis tend.
- Some of the known devices are those that serve to stabilize the vehicles and thereby Compensate lateral forces that occur. Problems would arise with everything these systems occur when the actuators (hydraulic, electromechanical) fail for any reason. The movements around the longitudinal axis of the car body would be then leave to yourself, i.e. would be a stabilization of the situation under certain conditions, depending on the location of the center of gravity relative to the tilt pole, not sufficient.
- the position stabilization in the case of passive emergency centering without active resetting of the emergency drive is under certain Conditions guaranteed.
- the centering quality is primarily depending on the center of gravity and the location of the tilt pole. If the center of gravity lies above the tilting pole, then it delivers lateral acceleration acting on a curve Moment that causes the car body to roll outwards. Out This is why it is important to make the whole system an energetic to impress a favorable level in the neutral 0 ° environment.
- the object of the present invention was to address this situation improve and in rail vehicles with transverse tilting device if the actuator or tilt drive fails, especially under Operating conditions of high-speed tilting trains, one sufficient passive stabilization through self-centering ensure.
- the basis of the passive self-centering according to the invention is the reversible energy input during the tilting process.
- the energy input (by the actuator) is a function of the set tilt angle and can be based on different performance profiles can be varied.
- Fig. 1 of the drawing shows a transverse inclination device purely schematically for one via spring systems 1, 1 'on a tilting traverse 2 arranged car body 3 of a rail vehicle.
- the incline cross member 2 is provided with at least two support surfaces 4, 4 ' equipped. These support surfaces 4, 4 'lie on rollers 5, 5' on which are rotatably mounted on the chassis 6 and whose axes of rotation run parallel to the longitudinal axis of the car.
- an actuator 7, 7 ' preferably an electromechanical Actuator, the inclination of the car body 3 with respect to the bogie 6 to the desired one Set value.
- the support surfaces 4, 4 ' are prismatic and arranged symmetrically to the central axis of the tilting crossmember 2.
- Fig. 1 the neutral tilt position, i.e. the 0 ° relative inclination, shown.
- the current location of the tilting pole is elementary Meaning.
- the orthogonal distance from the tilt pole to the resulting one Vector provides the lever arm the restoring torque. Thanks to the special contour shape of the support surfaces can be the location of the momentary pole and thus the effective lever arm can be manipulated as desired.
- the whole System is optimized for the momentary amount of the actuating force vector, so that on the required performance profile adjusted actuating force characteristic arises. I.e. that not only passive centering is guaranteed, it is the same possible to implement a limitation of the actuating force, as far as possible is independent of the vehicle weight.
- the drawing shows the roles as in the position shown 5, 5 'in concave depressions 8, 8' of the support surfaces 4, 4 ' lie in and by the sole action of gravity this position can be stabilized.
- the tilting traverse is essential in the construction according to the invention with the specially designed support surfaces, in particular the aforementioned wells for stabilization in the neutral tilt position for the roles interacting with it.
- the tilt cross beams on the car body and the Rollers are arranged on the bogie, as in the example shown, or vice versa, i.e. the roles on the car body and the Tilt traverse with the support surfaces on the bogie.
- Support surfaces 4, 4 'of each tilt cross-member 2 a prism-shaped Geometry (surfaces inclined towards each other).
- the support surfaces could instead of having a prismatic shape, any type of curve shape.
- the preferred electromechanical actuator is usually arranged between the tilt crossmember and the chassis.
