  • the middle door (5) takes her in the FIGS. 1, 4 . 11 and 16 shown closed starting position.
  • the two pulling and braking devices (20; 120) can also be arranged so that the cylinder-piston units (41; 141) point to the left.
  • the sequence of movements is then analogous to the procedure described above.
  • the pulling and braking device pair (11) may have two different pulling and braking devices (20; 120). These may for example have different stroke and / or different cross section. In this case, the speed profile over the stroke when closing from the right can be different than the speed profile over the hub when closing from the left.
  • One or both of the pulling and braking devices (20; 120) may also be constructed such that their displacement space is arranged between the piston and the cylinder head of the cylinder-piston unit. In such a device, the piston rod is retracted in the parking position and extended in the end position.
  • the definitions of the tensile and shear surfaces correspond to the above definition.
  • the pulling and braking devices (20, 120) have pneumatic retarding devices.
  • pneumatic dampers whose displacement space communicates with the environment (1).
  • hydraulic dampers is conceivable.
  • the piston rod may be spring-loaded extendable and abut with an abutment surface on the driving element.
  • the two stop parts (77, 78, 177, 178) of a carrier element (71, 171) can be connected to one another along their entire height.
  • the forces transmitted via the respective contact pairing (15, 16) can thus be transmitted to the respective support plate (76, 176) over a larger cross-sectional area.
  • FIG. 21 shows a driving element (71), the interconnected stop members (77, 78) in the longitudinal direction (82) of the driving element (71) have a smaller distance from each other than in the illustration of FIG. 5 ,
  • the thrust surface (85) in this embodiment is made larger than the traction surface (84).
  • the second driving element (171) may be identical.
  • the minimum distance d min of the tension (84; 184) and the thrust surface (85; 185) in the longitudinal direction (82) of the entraining element (71; 171) depends on the minimum overlap (s) of the traction surface (122) in the end position (122). 184) when hitting the thrust surface (85) located in the parking position (21), the head play (k) and the swivel angle (a) of the driving element (71) in the parking position (21).
  • the minimum distance thus results in d min ⁇ (s + k) / sin (a).
  • the minimum overlap (s) on impact is 2.8 millimeters, the head clearance (k) 0.35 millimeters and the pivot angle (a) 17 degrees. This results in the above-mentioned selected distance of the two surfaces (84, 85, 184, 185).
