Definitions
- the present invention relates to a transverse device between car body and chassis of a rail vehicle, in which the support between the car body and chassis about tilting traverses with support surfaces of predetermined geometry and rollers whose axes of rotation aligned in the vehicle longitudinal direction are, takes place and a between car body and chassis acting actuator is provided to the car body with respect to the chassis by a relative movement (Lateral movement with rotatory component) between the tilting traverses and the rollers controlled about its longitudinal axis tend.
- Position stabilization in case of passive emergency centering without active provision of the emergency drive is under certain Conditions guaranteed.
- the centering quality is first and foremost depending on the center of gravity and the location of the tilting pole. If the center of gravity is above the tilting pole, then the when passing through a curve acting lateral acceleration Moment that makes the car body roll outward. Out For this reason, it is important to energetically energize the entire system To impose favorable level in the neutral 0 ° environment.
- the object of the present invention was to address this situation improve and in rail vehicles with a transverse device in case of failure of the actuator or tilt drive, in particular under Operating conditions of high-speed tilting trains, a adequate passive position stabilization through self-centering sure.
- the basis of the inventive passive self-centering is the reversible energy input during the tilting process.
- the energy input is a function the set tilt angle and can be set to different performance profiles be varied.
- Fig. 1 of the drawing shows purely schematically a transverse device for one about spring systems 1, 1 'on a tilt traverse 2 arranged car body 3 of a rail vehicle.
- the tilt traverse 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 firmly on the chassis 6 and whose axes of rotation are parallel to the longitudinal axis of the carriage.
- an actuator 7, 7 ' preferably an electromechanical Actuator, allows the inclination of the car body 3 with respect to the bogie 6 on the respectively desired Set value.
- the support surfaces 4, 4 ' are prismatic and arranged symmetrically to the central axis of the tilt traverse 2.
- the orthogonal distance of the tilting pole to the resulting Vector provides the lever arm of the restoring moment. Due to the special contour shaping
- the supporting surfaces may be the location of the momentary pole and thus the effective lever arm can be manipulated arbitrarily.
- the whole System is optimized for the momentary amount of the force vector, so that one on the respectively demanded performance profile adapted force characteristic arises. That that not only a passive centering is guaranteed, it is the same possible to realize a Kraftkraftbegrenzung, the broadest possible regardless of the vehicle weight.
- the drawing shows, as in the position shown, the roles 5, 5 'in concave depressions 8, 8' of the support surfaces 4, 4 ' lie and by the sole action of gravity in stabilized in this position.
- the recesses 8, 8 ' go continuous on both sides, e.g. convex, in the straight sections the support surfaces 4, 4 'over, so that by the action of the actuators 7, 7 'any, each of the traveled route adapted inclination can be adjusted and maintained.
- Essential in the inventive construction is the tilt traverse with the specially designed support surfaces, in particular said depressions for stabilization in the neutral inclination for the co-operating roles.
- the tilting traverses on the car body and the Rollers be arranged on the bogie, as in the example shown, or vice versa, i. the rollers on the car body and the Tilting traverse with the support surfaces on the bogie.
- the support surfaces could instead of prismatic also have any kind of waveform.
- the preferably electromechanical actuator is usually arranged between tilt traverse and chassis.
- the power supply is a defined Increase the potential energy by manipulating the restoring moment in function of the tilt angle.
- the geometry of the Support surfaces provides the desired energy input characteristics, which ensures that in case of failure of the actuator the car body in the neutral tilt position (0 ° relative inclination to the chassis) is moved. Thanks to the wells in the support surfaces the system will be without active reset held in this position (stabilized).
- Figs. 2 and 3 illustrate the operations of the forces in dependence the angle of inclination.
