Large-capacity vehicle for transporting people, especially a rail vehicle, comprising carriages that are connected in an articulated manner

Abstract

A large-capacity vehicle is disclosed for transporting people, especially a rail vehicle. The vehicle includes carriages that are coupled by articulated connections, at least two of the carriages being respectively supported on a bogie or the undercarriage. All of the articulated connections enable the carriages to perform a turning movement about the vertical axis during cornering. For a vehicle that has more than three parts, at least one articulated connection is embodied in such a way that the vehicle can carry out pitching motions about the transversal axis in the event of dumping or tipping. One of the articulated connections includes a connection element that is embodied and connected to two carriages in such a way that pivoting and rolling motions can be carried out about the longitudinal axis of the vehicle.

The invention claimed is:

       7. The large-capacity vehicle as claimed in  claim 2 , wherein the component has a spring loading function. 
     
     
       8. The large-capacity vehicle as claimed in  claim 7 , wherein the component limits the rolling movements acting on the two carriages. 
     
     
       9. The large-capacity vehicle as claimed in  claim 7 , wherein the component limits the rolling movements acting on the carriages at one end, and limits the rolling movements acting on at least one of the ball and socket joints and a single-axle joint at the other end. 
     
     
       10. The large-capacity vehicle as claimed in  claim 2 , wherein the component limits the rolling movements acting on the two carriages. 
     
     
       11. The large-capacity vehicle as claimed in  claim 2 , wherein the component limits the rolling movements acting on the carriages at one end, and limits the rolling movements acting on at least one of the ball and socket joints and a single-axle joint at the other end. 
     
     
       12. The large-capacity vehicle as claimed in  claim 1 , wherein a rotational axis formed by at least one of the ball and socket joints and single-axis joints of the upper articulated joint and a rotational axis of the lower vehicle joint, movable in a spherical fashion and arranged centrally at a vertical distance between the carriages, lie on the same vertical axis. 
     
     
       13. A large-capacity vehicle for transporting people, comprising:
 carriages coupled by lower articulated connections and by upper articulated connections, at least two carriages being respectively supported on at least one of a bogie and set of running gear, both the lower articulated connections and the upper articulated connections permitting turning movements of the carriages about the vertical axis when cornering, the vehicle including more than three parts, wherein at least one upper articulated connection is embodied in such a way that the vehicle can carry out pitching movements about a transverse axis when traveling through a depression or over an elevation, one of the upper articulated connections including a connecting element embodied and connected to the at least two carriages configured to permit pivoting and rolling movements about a longitudinal axis of the vehicle, wherein the connecting element of the upper articulated connection is embodied as a rigid connector rod and is connected to the two carriages via ball and socket joints and the connecting element of the upper articulated connection is embodied as a twistable connector rod and is connected to the two carriages via single-axle joints. 
 
     
     
       14. The large-capacity vehicle as claimed in  claim 13 , wherein a rotational axis formed by at least one of the ball and socket joints and the single-axle joints of the upper articulated joint and a rotational axis of the lower vehicle joint, movable in a spherical fashion and arranged centrally at a vertical distance between the carriages, lie on the same vertical axis. 
     
     
       15. The large-capacity vehicle as claimed in  claim 13 , wherein the rolling movements are limited by a component including a damping function. 
     
     
       16. A large-capacity vehicle for transporting people, comprising:
 a plurality of carriages coupled to one another by lower articulated connections and by upper articulated connections, the lower articulated connections and the upper articulated connections being configured to permit turning movements of the plurality of carriages about a vertical axis, wherein at least one upper articulated connection is configured to permit the vehicle to carry out pitching movements about a transverse axis, and is configured to permit pivoting and rolling movements about a longitudinal axis of the vehicle, wherein a connecting element of the upper articulated connection is embodied as a rigid connector rod and is connected to the two carriages via ball and socket joints.
