Definitions
- Rail vehicle with tilting technology The invention relates to a rail vehicle with tilting technology.
- Tilting technology systems known from the prior art, as described, for example, in EP 0619212, allow a curve inclination of up to 8 °. This can increase the speed in curves by up to 30% without affecting the ride comfort due to increased lateral acceleration.
- Tilting systems can basically be designed as passive or as active systems.
- the passive tilting technology usually the car bodies are suspended above their center of gravity on elevated extensions of the chassis carrier. As a result, they oscillate outwards in the lower area due to the centrifugal force and in the upper one inwards. The vibrations are calmed by damping elements.
- the tilt angle is limited to 3.5 °. As a result, the speed gain for bow travel is also significantly lower than for active systems, passive tilting technology therefore serves primarily to improve comfort.
- Tilting known, in which the car body is pivotally mounted by means of rollers and roller tracks.
- the invention has for its object to provide over the disadvantages mentioned toleranteres and easier tilting system.
- a rail vehicle with tilting technology in which the car body is mounted on at least two suspensions, and wherein at least one of the trolleys is connected via an active tilting system to the car body and wherein at least one other suspension via a passive tilting system with the Car body is connected.
- Chassis per car body a chassis with the active tilting system is sufficient.
- the inclination of the car body in the arc run of the rail vehicle is then impressed exclusively by means of an active tilting system.
- a further advantage results from the possibility of easy and exact monitoring of the active tilting technology system by means of simple software. In addition, the cost of wiring the tilting system is reduced.
- the at least one chassis which is connected via the passive tilting system to the car body, a Momentanpol that is in each tilt state of the car body as close to the center of gravity of the car body, preferably in the center of gravity of the car body.
- the instantaneous center is preferably in the center of gravity of the car body.
- the tilting state of the car body can then be returned to the horizontal ground state only by external force again - according to the invention by the active tilting system. Only by gravity in this case, no restoring moment is effected.
- the inclination of the car body is imprinted solely by that chassis, which is connected to the car body via the active tilting technology system.
- this avoids that the car body is uncontrollably twisted and loaded, as it can occur in chassis, which are all equipped with an active tilting technology system. A safety risk arising from such twisting by relieving individual wheels in the arc travel of the rail vehicle is thus avoided.
- the at least one chassis which is connected via the active tilting system to the car body, in each tilted state of the car body lying next to the line of gravity of gravity through the center of gravity of the car body instantaneous.
- the car body is pivotally mounted on the at least one further chassis with passive tilting system by means of rollers running in roller conveyors.
- a further advantageous embodiment results from the fact that the car body is pivotally connected to the at least one chassis with active tilting system by means of a pendulum mechanism.
- the car body can also be mounted pivotally on all chassis with passive tilting technology system and on all chassis with active tilting system by means of rollers running in roller conveyors.
- Such bearings have the advantage that they have a very low rolling resistance.
- smaller, less powerful and less expensive actuators can be used on the chassis with the active tilting technology system in comparison to the prior art, which convert the car body from Negeschreib in the horizontal ground state and vice versa.
- FIG. 1 shows an inventive rail vehicle with tilting technology.
- 2a shows a view of a rail vehicle according to the invention in section A.
- FIG. 2b shows a view of a rail vehicle according to the invention with inclined car body in section A.
- FIG. 3a shows a view of a rail vehicle according to the invention in section B.
- FIG. 3b shows a view of a rail vehicle according to the invention with a tilted car body in section B.
- the rail vehicle 1 shown in FIG. 1 has a first running gear 3 and a second running gear 6.
- On the trolley 3.6 is a car body 2, which has a longitudinal axis 15, stored.
- the second chassis 6 is connected via an active tilting system 4 to the car body 2 and the first chassis 3 is connected via a passive tilting system 5 with the car body 2.
- the inclination of the car body 2 is impressed exclusively by means of the active tilting system 4.
- the chassis 3 with the passive tilting system 5 follows the movements of the active tilting system 4, but it has no facilities or actuators for actively supporting a tilt of the car body 2.
- the rail vehicle 1 is shown in section A.
- the car body 2 is pivotally mounted on the first chassis 3 with the passive tilting system 5 by means of rollers 7 running in roller conveyors 8.
- the car body 2 is pivotable about the instantaneous pole P.
- the chassis 3 does not include means for actively supporting the inclination of the car body 2.
- the rail vehicle 1 is shown in an unsatisfied state, the horizontal ground state.
- the roller tracks 8 are inclined in different directions so that their extensions intersect at a point like the legs of a V.
- the rollers 7 and the roller conveyors 8 are arranged substantially symmetrically to the longitudinal axis 15 and to a vertical plane through the longitudinal axis 15 of the car body 2.
- 2b shows the rail vehicle 1 in section A with inclined car body 2.
- the car body 2 is pivotally mounted on the first chassis 3 with the passive tilting system 5 by rollers 7 running in roller conveyors 8.
- the carbody 2 is pivotable about the instantaneous pole P.
- the car body 2 is inclined in comparison to the representation in FIG. 2a in the first tilting direction 16; it is in the tilting state.
- the position of the instantaneous pole P does not change during the tilting process of the car body 2 - its position therefore coincides in each tilted state of the car body 2 with the instantaneous center P '.
- the instantaneous pole P ' is the angular momentary axis of rotation of the car body 2 in the tilted state.
- the passive tilting system 5 has a momentary pole P, which is preferably in the center of gravity S of the car body 2 in each tilting state of the car body 2. In this case, no restoring moment is caused by gravity, which returns the car body 2 by gravity again in the horizontal ground state.
- the tilting state of the car body 2 can be returned to the ground state only by external force.
- the inclination of the car body 2 is impressed solely by the second chassis 6 with the active tilting system 4.
- the rail vehicle 1 is shown in section B.
- the second chassis 6 is connected via the active tilting system 4 to the car body 2.
- the active tilting system 4 is executed in this embodiment as a pendulum mechanism.
- the pendulum mechanism comprises two support elements 9 connected to the floor of the car body 2.
- the support elements 9 have first joints 10 which realize a rotatable connection with pendulum elements 11.
- the pendulum elements 11 are pivotally connected to a crossbeam 13 via second joints 12.
- the cross member 13 is connected to the second chassis 6.
- Either the support elements 9 can be rigidly connected to the car body 2 or the cross member 13 can be rigidly connected to the second chassis 6.
- Actuators 14 are provided between the traverse 13 and the carrier elements 9, which effect the inclination of the car body 2 about the instantaneous pole P.
- 3b shows the rail vehicle 1 in section B, but in an inclined state - in the tilting state.
- the second chassis 6 is connected via the active tilting system 4 to the car body 2.
- the car body 2 is inclined in the second direction of rotation 17 - he is in the tilting state.
- the instantaneous pole P moves during the tilting process of the car body 2 in the second direction of rotation 17 on a pole curve 18 from P to P '.
- the instantaneous pole P 'of the active tilting system 4 is in each tilted state of the car body 2 next to the line of gravity of gravity through the center of gravity S of the car body 2. This occurs in each tilting state a restoring moment, which acts in favor of the horizontal ground state of the car body 2.
- the vehicle body 2 can also be mounted pivotably on all running gears 3, 6 with passive tilting technology system 5 and on all running gears 3, 6 with active tilting technology system 4 by means of rollers 7 running in roller conveyors 8.
- Such bearings have the advantage that they have a very low rolling resistance.
- smaller, less powerful and less expensive actuators 14 can be used on the chassis 6 with the active tilting system 4 in comparison to the prior art, which convert the car body 2 from the tilting state into the horizontal ground state and vice versa.
