Definitions

  • the invention relates to a chassis for rail vehicles with a magnetic rail brake or an eddy current brake, the braking body of which is lowered or raised by means of a drive device fastened to a carrier of the chassis frame between an upper rest position and a lower active position and supported in both positions by stops.
  • the invention has for its object to design a chassis of the generic type so that the previously described construction costs are avoided and a much better, torque-free power flow can be achieved.
  • the drive device holding the carrier of the chassis frame does not perform any resilient movements with respect to the rail, so that there is a constant distance between the carrier and the rail and that this carrier also has the stops supporting the brake body in its operative position , which are arranged to avoid moments in the direction of action of the forces occurring.
  • the chassis shown has a frame which consists of two longitudinal beams 1 and brackets 1a attached to them.
  • the brackets 1a are each articulated to the opposite side member 1.
  • At the fork-shaped ends 1b of the side members 1 there are bearings 1c for shaft pieces 2a of wheels 2.
  • a suspension of the frame on the wheel bearings, which is inherently common in running gear or bogies, is not present here and is not necessary because of the relatively small mass of the frame.
  • a brake body 3 of a magnetic rail brake or an eddy current brake is arranged below each side member 1.
  • the brake body 3 can be adjusted between an upper rest position and a lower operative position by means of a drive device 4 - for example by means of two compressed air-actuated and spring-loaded cylinders.
  • the cylinders of the drive device 4 held on brackets 1d of the longitudinal beam 1 are diagonally opposite arranged above.
  • the cylinders of the drive device 4 are located in the longitudinal axis of the side member 1.
  • Each brake body 3 is held in its upper rest position by the spring biasing force of the drive device 4, by two (FIGS. 1A and 2 A) or four (FIGS. 1 B and 2 B) spring elements 5 (see FIG. 5, upper half of the figure) opposite the respective side member 1 vertically cushioned and fixed in the horizontal plane by a stop device 6 (see FIG. 5, lower half of the figure).
  • the spring elements 5 are connected by screws 5a to the side members 1 and to an upper part 6a of the stop device 6 designed in accordance with DE-PS 24 15 858.
  • This upper part 6a interacts with a centering cone 6b fastened to the brake body 3, which can be adjusted precisely by means of an eccentric bushing 6c.
  • the side member 1 In order to absorb the reaction forces occurring during braking without torque, the side member 1 has stops le arranged in the effective direction of these forces. These stops 1e can be designed as simple longitudinal stops (see FIG. 2A) in the magnetic rail brake.
  • the stops 1e are effective in addition to their function in the longitudinal direction, vertically downward and in the transverse direction.
  • the respective stop le has a receptacle 1f for a cam 3b on a cantilever arm 3a of the brake body 3.
  • the height of the receptacle lf is adjustable (elongated hole for clamping screws, toothed contact surfaces) connected to the stop 1e, this allows the desired air gap between the brake body 3 and the rail 7 to be easily adjusted during initial assembly or readjusted when the wheels 2 are worn.
  • the lowered brake body 3 is fixed in the transverse direction via the side surfaces of the receptacle 1f and the cam 3b. These side surfaces are designed prismatic in order to enable the cam 3b to be easily threaded into the receptacle 1f when the brake body 3 is lowered.
