Definitions
- the brake pad changeover device takes on this task.
- a further embodiment variant is provided by the solution according to patent specification DD 26970, in which the guide length of the brake shoe by a second Guide in the central area of the brake triangle, which is rigid with the Brake shoe is connected is guaranteed.
- This variant is especially the protection of the sliding surfaces from dirt and snow as well the multiplicity disadvantageous.
- the two brake block shoes of a brake triangle were patented a common spring pot connected to each other as end position securing. There this spring cup has no connection to the brake triangle itself, apply The above statements on the changeover path and play of the driving lug are analogous.
- the invention is based on the object of an automatic To create brake pad changeover device, which is independent of the type of the wheel change wheel set are used for today's modern Vehicles can safely transmit high brake pad forces, while doing so is of simple construction, which is light and comprehensive Pollution, ice and snow can be protected with a simple suspension of the brake shoe has a high security against unwanted Switch as a result of braking reaction forces and friction vibrations from the Braking has a, especially on the controlling driver elements low wear due to sufficient distance from the wheel center and can still be converted with high reliability.
- the object is achieved in that the brake shoe, which drive tabs with a large safety distance to the wheel rim have, in a conventional way according to standard brake triangles on one Cones are arranged.
- This spigot protrudes taking into account the strengthening required cross-sectional enlargement in the hollow Push strut of the brake triangle into it and is there in two sliding bushes guided.
- a bellows protects the inner one between the pin and the brake triangle Mechanism against contamination.
- the sliding bushes in the brake triangle can arranged at a very large distance due to the spatial conditions be so that the shifting process is not endangered by self-locking.
- the suspension of the brake shoe on The undercarriage of the car or bogie frame is made in Center of gravity suspension, depending on the spatial options either with crowned Bolts and bushings so that the brake shoe hanging iron is always slightly slanted sets and the resulting transverse forces through the end position securing can be included or by means of a sliding storage, wherein Driver of the brake shoe a certain swinging of the hanging iron allow. If the changeover paths are sufficiently large, the changeover can also be carried out of the two sides take place independently of one another, the End position is then secured via a spring-loaded toggle lever drive.
- Fig. 1 shows the top view of a lane change wheel set (1) with the section through the brake pad change-over device according to the invention in the position gauge 1 (Sp1).
- Fig. 2 shows the same in position track 2 (Sp2).
- Fig. 3 shows the view of the locking mechanism. 4 and 5 show variants of the locking linkage, while FIGS. 6 and 7 show the possible suspension of the brake shoe (4,4 ') on the base.
- the lane change wheel set (1) is in the track gauge 1 position (Sp1), the two drive tabs (2 and 2 'or 3 and 3') of each brake shoe (4 and 4 ') are at a distance s "from the wheel rim (5 and 5 ') of the wheelset (1).
- the brake shoe (4, 4 ') are rotatably mounted on the pin (6 and 6') and secured with a conventional cotter pin (7) or the like.
- the cones (6,6 ') are in turn stored in the brake triangle (8), the bearing points with the non-metallic sliding bushes (9 or 9 ') and (10 or 10') are.
- the bushings (9,9 ') and (10, 10') also serve as end stops for the pin (6,6 '), which is why this with the stops (11 or 11') and (12 or 12 ') is equipped.
- the stop (12 and 12) is removable, so that the pins (6,6 ') are inserted from the outside into the brake triangle (8) can.
- Fig. 6 shows that the brake shoe (4) with the crowned bolt (20) on pivotable brake pad hanging iron (21) is suspended, which in turn with a spherical bolt (22) is suspended in the brake pad hanging iron bearing (23).
- the center of the brake shoe hanging iron bearing (23) is in the middle (u4) of the changeover path u2 "of a wheel rim (5), so that the brake pad hanging iron (21) hangs at an angle.
- the wheel rim (5) shifts by the change-over distance during the change-over process from Sp1 to Sp2 u2 ", where u "represents the track width difference between the two track widths.
- u represents the track width difference between the two track widths.
- the corresponding games s "between the wheel rims (5 and 5 ') and the driving lugs (2 and 3).
- the pins (6,6') are now pulled out of the brake triangle (8), which simultaneously causes the locking crankshaft to rotate (17).
- the two pins (6, 6 ') can only move simultaneously at the same time, on the other hand, the pins (6, 6') must work against the force of the locking springs (19 and 19 ').
- FIG. 4 Another variant of the end position design is shown in FIG. 4 the inner bearing (10,10 ') of the pin (6,6') designed such that these by two sliders (24 and 24 ') opposite the brake triangle (8) is guided and on the bolt (25 and 25 ') at the same time Support connecting rod (26 and 26 ') to the locking crankshaft (17).
- FIG. 5 shows - on the bolt (25, 25 ') Support toggle lever (27 and 27 '), which at its end through the Locking spring (19,19 ') are loaded and thus secure the end position and support the changeover movement.
- the Locking shaft (17) executed without the levers (18).
- the stops (28,28 ') and (29,29') of the Sliders (24,24 ') simultaneously as a movement limitation for the end position of the Pin (6,6 ') so that they do not require any stops (11, 11' or 12.12 ').
- the coupling can also two pins (6 and 6 ') with the brake triangle (8) via the locking shaft (17) can be dispensed with, as shown in FIG. 5.
- Fig. 7 shows a possible embodiment of the brake block hanging iron
- the brake pad hanging iron (21) is laterally displaceable on the bolt (30) of the brake shoe hanging iron bearing (31) and the stops (32 or 32 ') on the brake shoe (4) ensure that a certain amount is observed Pendelweg the entrainment of the brake pad hanging iron (21).
