Definitions

  • the invention relates to a rail vehicle, in particular a tram or light rail car for local traffic, where a body and a chassis in the longitudinal direction are interconnected by at least one handlebar.
  • undercarriage includes powered and non-powered Undercarriages with two or four wheels, in pairs connected by a wheelset shaft or as idler gears can be executed, as well as corresponding drive and Bogies or bogies.
  • the state of the art also includes chassis modules and passenger modules formed low-floor vehicles with the Features mentioned in the preamble of claim 1 - see for this.
  • B. the magazine "Der Nah Colour" 10/95 pages 79 to 82.
  • Figure 4 on page 81 shows an engine with a trailing arm Handlebar pair, the opposite trailing arm is covered by the chassis frame in the illustration.
  • Figure 4 is also a transverse damper remove the possible between chassis and body Transverse movements are usually affected by here mechanical stops, not shown, are limited.
  • the invention is based on the knowledge that it With regard to a reversal of the running direction of running gear is desirable, especially by a or several trailing arms represented interface so interpret that a respective chassis quickly and simply below the same car body (head area or construction of a chassis module) arranged rotated by 180 ° can be.
  • the object of the invention is therefore the technical necessary to meet this requirement Specify design.
  • This task is solved in the first combination of features.
  • the symmetry created by this solution advantageously allows a quick reversal of the running direction of the chassis, for which only the trailing arm (or trailing arms) from the associated receptacle on the car body disconnect and then reconnect there.
  • the the Force transmission into the car body serving receptacle remains firmly attached. So the vehicle can move a lot short time again for the transportation of passengers be used.
  • the respective undercarriage 2 exists essentially from a frame 2a and four idler gears 2b, the frame 2a with attachments 2c for secondary springs and brackets 2d equipped for vertical dampers is.
  • the chassis 2 is with the one above Car body 1 by two links 3 in the longitudinal direction connected to transmit power. Also, between that Chassis 2 and the body 1 a cross damper 5 (see also Fig. 4) and stops 2e to limit the transverse movements provided with those not shown here interact elastic elements.
  • these are the car body 1 facing connector 3a of the handlebar 3 and its on Car body 1 attached receptacle 4 with their respective Cross axes together in the perpendicular to the vehicle longitudinal axis L running center plane M of the chassis 2 arranged.
  • the connection 5a facing the car body 1 the transverse damper 5 and attached to the body 1 Recording 6 can with sufficient space with their respective longitudinal axes in the middle of the Vehicle longitudinal axis L lie.
  • FIGS. 2 and 3 it has the body 1 facing connection 3a of the handlebar 3 - different to Fig. 1 - a longitudinal distance a to the center plane M of the undercarriage 2.
  • the wagon body side Recording 4 to bridge this longitudinal distance a equipped with a connector 4a the longitudinal axis of the vehicle L can be placed in front of or behind the Center plane M is screwed to the receptacle 4.
  • the one Car body 1 facing connection 5a of the transverse damper 5 has a transverse distance b to the longitudinal axis L of the chassis on.
  • a modification of the invention exists therein the receptacles 4 for the trailing arms 3 and Recording 6 for the transverse damper 5 on a common Attach the plate, which is screwed to the body 1 to be fastened.
  • the plate has a symmetrical hole pattern, so that it corresponds accordingly the desired running direction of the chassis 2 either in a first position or in a 180 ° position rotated second position connected to the car body 1 can be.
  • chassis and car body - all other mechanical interfaces between chassis and car body - such as the stops 2e for limiting the transverse movements, the attachments 2c of the secondary springs and the brackets 2d the vertical damper - and also the electrical Joints between the chassis and the body also arrange so that the wanted simple Reversing the running direction of the chassis ensures is.
