Definitions

• the invention relates to a rail vehicle according to the preamble of the first claim.
• the invention has for its object to take measures in a rail vehicle according to the preamble of the first claim, by means of which an equalization of the axle load in the area of the transition from the locomotive to the body is made possible. This object is achieved according to the invention by the characterizing features of the first claim.
• the axle load on the common running gear can be varied by choosing the contact point of the elastic support elements which are arranged between the running gear and in particular the heavy power car.
• the support for the car body is preferably in a vertical projection above the wheel axis. Accordingly, if the contact point of the elastic support elements carrying the power car is shifted towards the car body, the axle load increases on the car body-side wheel set and drops accordingly on the power head-side wheel set.
• the drive therefore preferably has a frame with two long beams running parallel to one another in the direction of travel, on which the support points can be selected depending on the necessary supporting force for the drive head and the body.
• the end of the power car end facing away from the driver's cab is, however, preferably mounted on a power bogie.
• the elastic support elements between the drive head and the same drive are preferably designed as coil springs, which are particularly useful for high loads.
• the car body on this common drive is preferably supported on two supporting columns that are spaced apart from one another transversely to the direction of travel, elastic intermediate layers, in particular air springs, on which the car body rests are located at the upper end of the supporting columns.
• the support points of the car body are above his Center of gravity so that the car body can tilt towards the drive when cornering and at high speed due to the centrifugal forces that occur (Talgo technology).
• the coupling between the power car and the neighboring car body is supported by coupling rods, which are articulated on the one hand on the chassis and on the other hand on the power car or on the car body, so that forces occurring between the power head and car body during braking, starting or during operation are not supported by the elastic support elements , but are primarily transmitted from the drive, which is rigid at least in the longitudinal direction, without impairing the free mobility.
• the coupling rod connected to the driving head is preferably longer than the coupling rod connected to the car body, the latter in particular running at least approximately horizontally, while the coupling head-side coupling rod is inclined from the drive to the front end of the driving head. When driving straight ahead, the coupling rods lie in a common vertical plane with the vehicle's longitudinal axis.
• the wheels of the individual wheel sets are preferably equipped with a lane changing device, so that the entire rail vehicle can be changed over when the track width changes, particularly in cross-border traffic.
• rubber-elastic intermediate layers can also be provided as primary suspension between the wheel bearings and the undercarriage frame in order to ensure smooth running of the common drive designed in the manner of a Jacob's bogie.
• Fig. 1 shows a rail vehicle with a power car and subsequent car bodies
• Fig. 2 shows the drive arrangement between the power car and the adjacent car body in a basic side view
• Fig. 3 shows the arrangement of FIG. 2 in a plan view.
• a rail vehicle for rail traffic at high speeds, which at its peak is at least 100 km per hour, has a power car 1 and at least one adjacent adjacent car 2, to which further cars 3 can connect.
• the drive head 1 contains only a driver's cab 4 and electrical and mechanical components for the drive and the control, the drive being effected via a drive bogie 5 provided in the area of the driver's cab 4 with drive otor / s.
• the opposite end of the car body 2 can be supported on a further adjacent car body 3 via an articulated coupling 7, it being possible for a drive 8 to be arranged under the relevant end of the car body 3.1 in the region of the articulated coupling 7.
• the body 2.1 serves in particular for the transportation of people.
• the drive 6 jointly assigned to the driving head 1 and the car body 2.1 has two axles 9, 10 and accordingly two wheel sets, each with two rail wheels 11.
• the axles 9, 10 are mounted in a common running gear frame 13, long beams 14 extending in the direction of travel being provided, which are preferably rigidly connected to one another in the region of the wheel axles 9 and 10, respectively, via a cross member 15.
• the distance between the axes 9, 10 in the present case is more than twice the diameter of the wheels 11.
• the long beams 14 and the cross beams 15 form the running gear frame 13, the beams 14, 15 running in pairs parallel to one another.
• the end of the driving head 1 adjacent to the car body 2.1 is supported on the drive 6 via elastic support elements 16.
• These support elements 16 are by Helical springs arranged in pairs are formed, two helical springs in each case standing one behind the other on the long beams 14 in the longitudinal direction of the long beams 14.
• the car body 2.1 is supported in a vertical projection above the associated wheel axle 10 on the drive 6.
• two rigid support pillars 17, which are at right angles to one another at a distance from one another on the drive 6 and in particular on the long beams 14, are provided at their upper ends and on which the car body 2.1 rests by means of a bracket 19.
• the brackets 19 are arranged so high that the body 2.1 is supported above the horizontal plane receiving its center of gravity.
• the car body 2.1 can passively incline such that its base region swivels outward of the arc, so that the centrifugal force effect on passengers and other goods to be transported is correspondingly reduced.
• a coupling rod 20 or 21 is gimbally articulated on both ends of the chassis 6 in the longitudinal center thereof, the Coupling rod 20 articulated in the area of the axis 9 is also gimbally connected to the bottom 22 of the drive head 1 via a joint pin 23.
• This coupling rod 20 extends from the drive 6 to the drive bogie 5 ascending, while the coupling rod 21 runs from the drive 6 approximately in a horizontal position to a pivot pin 24 which is fixed to the floor 25 of the body 2.1.
• the cardanic joints of the coupling rods 20, 21 can be designed in the manner of ball-and-socket joints or have rubber-elastic inserts as the joint means. It is connected to the power car 1
• Coupling rod 20 is longer than the coupling rod 21 connected to the car body 2.1.
• a rubber arranged elastic intermediate layer 26 which serves as the primary suspension and contributes to increasing the smooth running of the drive 6.
• the possibility is given, in particular by moving the support points of the screw springs 16 from the power car side axis 9 to the car side, trailing axle 10, the heavy load of Power train 1 to partially shift to the axle 10 associated with the carriage 2 until an approximately equal load on the axles 9 and 10 is reached.
• the driving head 1 can be supported by elastic support elements 16 which differ significantly in their working characteristics from those which have the support elements 17, 18 provided for the car body 2.1.
• only a common drive 6 needs to be provided for the mutually facing ends of the power car 1 and the body 2.1, which at the same time takes over the coupling function for the transmission of traction forces.
• level control of the car body can be carried out without influencing the power car 1, because both vehicle parts are supported separately on the common drive 6;
• wheel sets can be used which are equipped with a lane change device (Talgo system).
• Various attachments such as e.g. Damper and the like.
• the distance between the wheelsets is selected according to the structural and weight requirements.
• the distance of the coil springs from the wheelsets is determined by the mass of the power car to be supported, the body 2.1 and the distribution of the masses in the chassis itself in order to achieve a balanced wheel mass on the axles 9 and 10.
