Definitions

  • the invention relates to a block brake for rail vehicles, according to the preamble of claim 1.
  • Block brakes for rail vehicles are known from practice, particularly in the field of freight transport, via which up to a max. permissible speed of 120 km / h the entire braking of the rail vehicle takes place.
  • the brake blocks consisting of brake block shoes and brake block soles act directly on the tread of the wheel tire of the wheel set.
  • the brake pads are suspended on a brake crossbar.
  • the brake block shoes with the brake crossmember are articulated in the rail vehicle or in the chassis of the rail vehicle on its frame and are acted upon by a brake cylinder via a brake pull rod with the interposition of the center brake linkage and any connecting levers between the brake crossbars.
  • This block brake described above fulfills its task up to the above-mentioned speed satisfactorily with the loads of up to 22.5 t per axle which are common in freight transport and consists of simple, economically manageable components which can be maintained with little effort.
  • a disadvantage has been found, however, that the braking heat generated during braking leads to damage to the wheel tire and the tread.
  • a block brake of the type mentioned is known from US-A-2169751, in which a brake cylinder acts on a crossbar on a brake linkage, which in turn is connected to brake blocks, which are on both sides radially on the lateral surfaces of the rotationally symmetrical brake bodies arranged on the wheel set shaft between the wheel disks lie on.
  • the traverse is designed as a straight lever, with which, depending on friction and dimensional deviations, an inclined loading of the enclosed brake linkage is possible. This should generally be avoided.
  • the present invention has the task of creating a block brake in which the braking force is applied as uniformly as possible. This is achieved by the features of the characterizing part of claim 1.
  • the wheel axle is kept free of additional longitudinal forces, so that the wheel set can largely adjust itself to the course of the track even when braking.
  • the brake block shoes are suspended from brake block hangers and are mounted on a brake crossmember.
  • the brake crossmember is further configured as a brake triangle when two brake bodies are arranged on the wheelset shaft.
  • each brake pad can be guided axially on the brake body.
  • the brake crossmember is guided laterally on the frame of the chassis or the underframe of the rail vehicle.
  • the wheel set (1) which essentially consists of the wheel set shaft (2) with the wheel disks (3), is, as is known from practice, via external axle bearings (4) and leaf suspension springs (not shown) with the interposition of shackle hangers (also not shown) on spring brackets (5 ) of the base (6) of the rail freight wagon.
  • a rotationally symmetrical brake body (7) is arranged on the wheelset shaft (2) on both sides of the central longitudinal axis of the rail freight wagon.
  • the rotationally symmetrical brake body (7) has a cylindrical outer surface (8) and a flange (9) projecting beyond the outer surface (8).
  • a brake cross member (11) is articulated on both sides of the wheel set (1) via brake block hangers (10).
  • the brake crossmember (11) carries a brake block (14) consisting of a brake block sole (12) and a brake block shoe (13) at each of its two longitudinal ends.
  • the brake block soles (12) of each brake block shoe (13) lie in front of the outer surface (8) of the brake body (7).
  • Each brake crossmember (11) is articulated in the center on a brake lever (15), a brake lever (15) with its upwardly projecting end being articulated on a fixed point bearing (16) of the underframe (6) of the rail freight wagon.
  • the second brake lever (15) carries at its upper free end (marked A) a brake cable, not shown.
  • both brake levers (15) are articulated to one another by a brake lever connector (17).
  • the brake lever (15) carrying the brake cable rod is further articulated via its articulation (18) carrying the brake lever connector (17) to a brake hanger (19), which is also articulated to the base frame (6) of the rail freight wagon.
  • the wheel set (1) is braked by means of a brake cylinder by means of the brake cable rod (not shown) and a center brake linkage (also not known from practice) in that the brake blocks (14) via the brake block soles (12) against the lateral surface (8) of the brake body ( 7) can be pressed.
  • a wheel flange on each longitudinal side of the brake body (7) instead of the one wheel flange (9) of the brake body (7) or the lateral surface (8) of the brake body (7) with a brake block (14) leading laterally Contour, for example convex or concave. It is also conceivable for the lateral guidance of the brake crossmember (11) to be guided by lateral guides (20) in the base of the rail freight wagon.
  • the brake blocks (14) can be guided onto the brake body (7) in such a way that the required transverse movements of the wheel set (1) take place relative to the brake crossmember (11) and thus to the brake block (14) and on the other hand in such a way that the transverse movements of the wheelset (1) are transmitted to the brake crossmember (11) and thus to the brake pads (14) and that existing brake rod linkage composed of brake pads and brake crossmember oscillates with these transverse movements.
