Definitions
- the invention relates to a rail-bound vehicle segment with a support frame on at least one pair of wheels, with a shell on the support frame and with a floor in the shell to accommodate vehicle installations, seats etc.
- the invention further relates to a vehicle association.
- the track arches are raised
- the outer rail was built and, on the other hand, passed through at a lower speed.
- the elevation of the outer rail causes the vehicle to tilt Inside of the track arch.
- the force component partially compensating the centrifugal force, the downhill force generated.
- the compensation of the centrifugal force with the help of the track cant are narrow limits set by the fact that vehicles in the track curve to the Have to come to a stand.
- tilting technique primarily serves to compensate the centrifugal force acting when traveling through a curved track to such an extent that cornering is comfortable for the vehicle occupants even at high speeds. Through the use of the tilting technology it is achieved that vehicle associations with vehicle segments equipped in this way can drive through bends at high speed and achieve a reduced travel time between the start and destination station.
- the body of the well-known vehicle segments with tilting technology is formed by a car body mounted on a base.
- a suspension system for vehicles of a general type is already known from US 2,859,711. especially known for rail vehicles, in which one of the support frame and Vehicle hull structurally separate, vertical shocks, but also lateral Catch forces that could lead to shifts and in their Limit effects.
- this carrier vessel swings around one Pivotal point above the common center of gravity of empty vehicle mass and load mass suspended, stored on a buoyancy chamber and with provided side damping bodies.
- this is not one Tilting technology in the sense introduced above, but only a passive one Suspension system that is not used for active centrifugal force compensation. It is this Suspension system not possible, the carrier is controlled or regulated in this way align that the resultant of gravity and centrifugal force is approximately vertical is directed against the bottom of the support vessel.
- a tilt angle of the fuselage is common in vehicle segments equipped with tilting technology and operated by Deutsche Bahn AG, which partially compensates for the lateral acceleration down to a value of approximately 1.0m / s 2 .
- This value of the remaining lateral acceleration is perceived as tolerable by vehicle occupants and is physiologically harmless.
- UK 1 508 173 discloses a passive tilting technique of the type one Pendulum.
- the car body can be pivoted with the help of a Secondary suspension that attacks under the roof of the car body and its load transmitted to the chassis via columns Since the center of gravity of the body and load transported in it lies below the suspension, generated when driving through of track arches, the radially outward centrifugal force is a torque that a Pivoting movement of the car body around one in the plane of the suspension longitudinal vehicle axis.
- EP 808 758 A1 is a vehicle segment known in which the fuselage is attached to a cross member, which is on one below lying carriage is pivotally mounted.
- pantographs must adapt to the respective inclination of the fuselage can, on the one hand, without contact with the overhead contact line lose and without exerting otherwise harmful forces on the catenary.
- the object of the invention is so a vehicle segment of the type mentioned to further develop that on a bow ride on occupants or transported goods acting side forces with the help of a simple, light and space-saving construction can be at least partially compensated.
- Another object of the invention is. one Specify vehicle association that the passage of curves with high Speed with low wear on track and wheels possible.
- the task is for a rail-bound vehicle segment by the Subject of claim 1 and for a vehicle association by the Subject of claim 30 solved.
- the floor is about a vehicle longitudinal axis running in the direction of travel relative to the shell and can be swiveled in accordance with predetermined control values.
- predetermined control values are preferably the specification of angles of inclination.
- Shell, support frame and chassis take part in the swiveling movement of the floor not part.
- the Nelge device with storage, etc. alone carries the floor with the built-in components and transport loads. It can therefore be less expensive and in particular be made lighter. This also makes the wheels of the Protected vehicle segments and the rails.
- the outer contours of the vehicle segment can Solutions when driving through a track curve despite the centrifugal kart compensation achieved remain unchanged because only the bottom is inside the bowl performs the tilt movement required for this.
- the centrifugal force compensation is in integrated the fuselage of the vehicle segment and imperceptible from the outside.
- the vehicle body is not considered Whole is pivoted, the unused light space can Track to widen the vehicle body and thus to enlarge it of the available interior.
- the vehicle segment according to the invention can be used in a conventional manner rigidly trained, but also with a section along its length hinged shell can be realized.
- the centrifugal force compensation according to the invention only the mobility of the soil relative to the shell is important.
- the support frame extends within the surrounding shell over the entire Length and width of the vehicle segment and takes over the power line in vertical Direction to the chassis and part of the acting in the longitudinal direction Acceleration and braking forces.
- the shell does not have any essential supporting functions take over, but directs acceleration and braking forces and takes in one Vehicle association the longitudinal dynamics arising in the fuselage when driving.
- Bottom and shell are spaced so far that, on the one hand, the mobility of the Ground for centrifugal force compensation and - if necessary - the articulation the shell when driving through bends, crests or depressions is restricted.
- the distance between the bottom and the shell is shown in an example bridging elastic seals so that there is no visible gap.
- the Seals also prevent air exchange and the occurrence of Sound bridges to the underfloor.
- actuating and storage means for Run or store the floor provided that the floor by at least one in Vehicle longitudinal axis running on the floor or below the floor can be pivoted to store.
- the actuating and storage means can also be designed such that the floor about at least one longitudinal vehicle axis running above the floor is pivotable.
- the vehicle's longitudinal axis is about that the floor is pivotable, does not run in the floor itself, the floor moves relative to the support frame and shell also in the transverse direction, so one is approaching Inside of the shell.
- a longitudinal center plane which is the center of the axis of the wheel pair and the vehicle's longitudinal axis, around which the floor is pivoted, can cut vertically will run differently in different embodiments. Is only one provided such pivot axis, the actuating and storage means store the floor preferably pivotable about a vehicle longitudinal axis in the longitudinal center plane runs.
- the positioning and storage means can also store the floor in such a way that selected catfish either around a first or a second vehicle longitudinal axis is pivotable.
- the first and second vehicle longitudinal axes run parallel to each other in a plane that is perpendicular to the longitudinal median plane mentioned.
- Each of the two vehicle longitudinal axes forming the swivel axes is one Swivel direction is assigned. That is, for an inclination of the floor after it is turned outside the vehicle's longitudinal axis, for an inclination towards bow pivoted around the other longitudinal axis of the vehicle
- the first and the second longitudinal vehicle axes run preferably on both sides of the median longitudinal plane, each with the same Distance to the median longitudinal plane. This has the advantage of being active Pivoting the floor required actuators when pivoting each predominantly only have to bear the load on each side of the floor that the as Vehicle longitudinal axis serving the pivot axis is not included.
- the positioning and storage means preferably support the floor on the support frame.
- the floor fulfills with the carrying of parts of the interior and the transport boxes predominantly tasks of vertical power flow within the vehicle segment. Other components take over the longitudinal force flow.
- the positioning and Storage means support the floor on the support frame over its entire extent in the vehicle's longitudinal direction. For this purpose, they have a corresponding longitudinal extension on or are distributed in the longitudinal direction of the vehicle.
- the floor itself can therefore be built comparatively easily.
- the shell is in this embodiment largely freed from vertical loads.
- the positioning and storage means support the floor in the Longitudinal median plane on the support frame.
- Support for better load distribution Setting and storage means the floor on both sides of the median longitudinal plane on the Support frame from.
- positioning and Storage means provided only a short distance from the longitudinal median plane.
- the Bearing points are moved closer together in the middle.
- the floor around two vehicle longitudinal axes running below the floor pivotable. Due to the different lengths of levers on both sides of a bearing point there is a stabilizing restoring torque when tilting.
- the positioning and Storage means preferably designed to be adjustable in height. This is particularly the case with Storage of the floor on the support frame on both sides of the longitudinal median plane advantageous.
- the actuating and storage means are pneumatic in one embodiment or operated hydropneumatically, for example, one or more Air springs, single or double-acting cylinders. Cylinders are included advantageously articulated on the floor and on the support frame to the Do not hinder the pivoting movement of the floor.
- the vehicle segment according to the invention have the actuating and storage means at least one with the support frame and on the other hand, connected to the ground, electrically driven steeping device for Generation of the swivel movement.
- the control elements can also be attached to the shell on the support frame.
- the electric one Drive has the advantage that the power supply of the steep device with little Effort and space requirements can be accomplished. The energy will be there anyway provided electrical power supply system of the train. Also the maintenance effort for electrical actuators is comparatively low. In contrast to hydraulic lines, electrical cables are also light.
- the actuator has one Spindle drive or a rack and pinion drive that is electric. with a conventional one Electric motor or a stepper motor is operated.
- the positioning and storage means as roller bearings or plain bearings between the floor and trained the support frame.
- the functions carry and place are separated, the positioning and storage means only take on the function of carrying.
- a pivoting movement of the floor are on the one hand with the shell or support frame and on the other hand to provide drive means connected to the ground, the Im Operation on the ground a perpendicular to the direction of travel, especially parallel to exert directional pushing or pulling force across its transverse extent.
- the drive means are double-acting, so they can exert pull or thrust in the lateral direction.
- the bottom has a downward face on its underside directed approach on which the drive means attack. The attacking force will redirected by the approach to driving the pivoting movement of the floor.
- the approach can extend through an opening through the support frame. This has the advantage that the lifting action is increased and the drive means one have to generate less force. However, there is corresponding space in the support frame and if necessary in the space below the support frame up to the shell. This can be done, for example, by providing a longitudinally extending one tub-like space in or below the support frame, which in its longitudinal extent it only omits the area of the undercarriage. This can take up additional units.
- the base is in a swiveling movement movable relative to the shell in a direction perpendicular to the direction of travel. This results inevitably in those embodiments in which the Swivel axis does not run in the floor itself, but below or above it. There are but also other forms of movement can be realized, to the following in more detail is received.
- the actuators and Storage means rolls or sliding elements on at least one rolling or Run slideway, which is transverse to the longitudinal axis of the vehicle and relative to the support frame is curved or inclined.
- the profile of the roller or slideway across The vehicle's longitudinal axis determines the pivoting movement of the floor.
- at arcuate curvature of the roller or slideway is determined by the radius of the arc determines the position of the swivel axis.
- the type and The extent of an additional translational movement of the floor can be predetermined.
- Assign the roller or slideways for example, the shape of a Longitudinal center plane inclined plane, so swivel and overlap Translation movement of the floor in a complex tilting movement.
- the setting and storage means Articulated supports (standing pendulums), which are articulated to the floor and to the supporting frame are.
- This embodiment has the same as the storage on roller or plain bearings Advantage that the centrifugal force contributes to the inclination of the ground Bracing causes one side to be lifted during lateral displacement and the other is lowered.
- Another advantage of this type of storage is the backward effect, which supports the movement of the floor back to its rest position when the outward centrifugal force decreases.
- suspension is part of the storage of the floor on the Support frame is storage, actuator and suspension can be compact, space-saving design can be connected in series. None arise from this fundamental constructive difficulties when the support by the Control elements are integrated into the storage at the same time. This is particularly the case with relative to the longitudinal center plane of the floor on both sides of the support frame realizable.
- the pivot position of the floor relative to the support frame is another Embodiment monitored using suitable sensors.
- the target position of the Interior floor is based on currently determined or retrieved, pre-stored Route data (track radius, track cant, cant ramp etc.) and based on the current state of motion of the vehicle segment (position, speed, Acceleration). By appropriate tax means prevents the sprung floor from sloping due to uneven loading device.
- the inner floor is provided relative to the support frame to the outside when the vehicle segment a track curve with an elevated outer rail below the compensation speed traverses.
- the compensation speed is the speed at the centrifugal lateral acceleration softens and that due to the Glels camber emerging slope downhill acceleration compensate exactly. If a track is curved at a speed below that Drive through the equalization speed or the vehicle must even be on the track curve stop, so the passengers in vehicles according to the state of the art pulled towards the inside of the arch by the predominant downhill force (gravity), which causes an uncomfortable sitting posture and walking within the Vehicle segments difficult
- objects lying on tables can slip or fall on the floor due to the uncompensated inclination. This inconvenience is avoided in the present embodiment.
- the uncompensated Determine downhill forces This can be done in a simple form that the track elevation, the speed and the current swivel position of the Interior floor can be determined. From this measurement data it can be determined how far the Slope acceleration accelerated by centrifugal lateral acceleration is. From this a target swivel position of the floor is calculated, with the full one Compensation is achieved. With the help of suitable, generally known control means then the movement of the inner floor into the pivot position calculated in this way In this embodiment, the inner floor is thus made for one Passengers swiveled into comfortable position while the vehicle segment was in Track arch with support frame and shell moves or stands inclined towards the inside of the arch
- Vibrations of the inner floor are in a further embodiment of the Invention suppresses, unless it is in the form of rectilinear movements in vertical Direction.
- the vibration ability of the floor in the vertical direction is additionally limited so that the vibrations do not affect the positioning movements Counter slope of the ground.
- a composed of several vehicle segments according to the invention Vehicle association initially stands out due to the comparatively light weight Construction of the vehicle segments through a low wear of rails and Wheels out.
- Tilting technology has the further advantage that its outer contour is like one Vehicle behaves without tilting technology. In this way, the clearance on the track for a large transverse extension of the vehicle segment can be used since none Additional scope is required for the inclination of the vehicle casing in the curve of the track is.
- the vehicle association according to the invention requires a comparative one low energy consumption, since not the shells as a whole, but only that Floors Within the shells with the vehicle fittings, seats etc. fastened in them be pivoted.
- the active tilting technology are at least in the front in the direction of travel Vehicle segment sensors for measuring the speed of the vehicle group, the radius of curvature of the track and the elevation of the track, as well as means for Control or regulation of the time course of the pivoting movement of the floors of the individual vehicle segments by evaluating the current measurement signals of the Sensors provided.
