Definitions
- the invention relates to a suspension according to the preamble of the claim 1.
- eddy current brakes of the generic type (DE-OS 26 14 298) is on the bogie frame on both sides of a bogie one each Actuating cylinder formed lifting device for the below the bogie frame brake carrier located on both sides of the wheelsets of the Rail vehicle provided.
- the brake carriers bear on their underside Brake magnets, which are lowered with the help of the brake carrier Braking position with a small and as constant as possible distance to the surface the rail and released, raised position are shiftable.
- the front ends of the brake carrier extending parallel to the rails are in guides rigidly attached to the wheel or axle bearings supported.
- the object of the invention is a suspension of the generic type, in particular for eddy current brakes, that extensive decoupling between the mass of the Eddy current brake and the wheelsets can be achieved.
- the wheel or axle bearing sets should remain unaffected by any functional positions the brake.
- the suspension uses the front ends to guide the Brake carrier of the freely pivotable arranged on the wheel or axle bearings Pendulum to decouple the respective parallel to the rails Brake carrier and the total mass associated with the brake carrier Achieve eddy current brake compared to the wheelsets.
- a decoupling between the eddy current brake mass and axle bearings or wheel sets ensured because the front ends of the Brake carrier under swiveling bracket through the axle bearing side Pendulum are limited displaceable in the transverse direction, preferably over exactly Defined spring characteristics and stop positions on the axle bearing in both Positions, or by separating the arms of the brake carrier and the Pendulum is such that the ends of the arms in the braking position on abutments rest in the form of pans and free in the raised release position are held against the pendulum bodies. Through defined stops at the same time the largest possible width of the brake magnets of the eddy current brake reached.
- the suspension is also suitable for Vertical adjustment i.e. for readjustment of the air gap between the brake magnets and the rail for the purpose of compensation of tire wear.
- it is preferably at least one of the articulation points of the two front arms of the suspension - both on the brake carrier as well as on the pendulum - adjustable.
- a bogie frame 1 is a side view Rail vehicle shown, on which an eddy current brake 3 in is arranged in the manner described below.
- the bogie frame 1 one side of the vehicle is resiliently supported on axle bearings 5 of two wheel sets, lifting bellows 7 connected to the bogie frame 1 onto the brake carrier 9 of the eddy current brake 3 act and this from the in Figure 1 shown braking position to raise in the release position shown in Figure 2 assets, as explained below.
- each of the arms 15 is one at its ends Brake carrier provided pivot axis 17, which is outward extending ends of the arms 15 each on a pendulum 19 on the axle bearing 5 are articulated. In this way, the arms 15 and the pendulums 19 are each rotatable about an axis running perpendicular to the image plane; on the opposite The arms 15 act according to FIGS. 3 and 4 with a brake carrier fixed Stop 21 together.
- Figure 3 shows the braking position of the eddy current brake, in which the Stop position of the arm 15 relative to the stop 21 is shown.
- Stop 21 is designed as an eccentric part rotatable about its axis; it other stop elements on which the brake is in are also possible Braking position supports and which are also adjustable to the stop position fixed in height.
- a fork 23 can be provided be used as a side guide for the pivoting movement of the arm 15 encompasses the end about the axis 17, as can be seen from FIGS. 3 and 4 to relieve.
- Vehicle limitation profile with the largest possible width of the magnets from Brake magnet is observed during operation.
- the arm 15 can be pivoted about the position I (axis 17) be, whereby the wheel set change with dismantled pendulum arrangement is hardly hindered.
- the pendulum 19 enables in both positions (braking and releasing position) free movement of the wheel sets in the X direction. Due to the pivoting of the Arms 15 around the axes 17 is in the release position the free deflection of the wheel sets guaranteed. Nevertheless, the brake magnets are in the Y direction constantly (brake and release position) on the axle bearing after the above Led way.
- FIGS. 6-8 of the drawing shown Another embodiment of the suspension is shown in FIGS. 6-8 of the drawing shown.
- the arm is 15 not articulated to the pendulum 19, but is at its end with a spherical support 29 provided in the braking position ( Figure 6) in a pan 31 rests on the underside of the pendulum 19.
- the pendulum is 19 in contrast to the embodiment according to the preceding figures 1-5 as a lever-side open housing is formed, which by the point III extending axis 33 is pivotable. Pins connected to the pendulum 35 are guided in bearings, not explained in detail, which on the Bottom of the axle bearing 5 are provided.
- the arm 15 is in the manner shown in FIG. 7 with the exception of one
- the possibility of changing the position explained below is held in a rotationally fixed manner, i.e. the arm 15 pivots from the transition from the braking position ( Figure 6) in the release position ( Figure 7) no longer around the one running through point I. Axis 17 down, but remains in the horizontal position.
- the end of the arm 15 opposite the support 29 non-rotatable between a spring 37 provided as a stop and a wedge 39 led.
- the wedge 39 with its serving to support the end 41 of the arm 15 Wedge surface 43 is in the illustrated embodiment of a Spindle 45 carried, which e.g. by means of an adjusting hexagon 47 or one comparable device is displaceable in the longitudinal direction, such that a setting explained below, i.e. limited rotation of the lever 15 is possible.
- the arm 15 is only in the braking position ( Figure 6 and 8) with its support 29 in the pan 31 of the pendulum 19.
- the arm 15 has a release position and accordingly the one connected to it Brake in the Y direction between the spaced on the inside of the pendulum Stops 49 against the axle bearing a mutual game, i.e. that in the release position a complete decoupling from the axle bearing is reached.
- the running behavior of the bogie is thus as low as possible Way influenced.
- After releasing the pad 29 from the pan 31 is consequently decoupling in the Z direction (FIG. 7) is also achieved.
- the point of support is Arms on the wedge surface 43 changeable.
- the wedge 39 is over the spindle 45 shifted in the X direction by turning the setting hexagon 47, such that that a limited pivoting of the arm 15 is achieved via the wedge surface 43 is and thus the relative altitude of the pad 29 compared to the Pan 31 can change.
- the arm 15 is non-rotatable in the release and braking positions and the degree of freedom, i.e. the decoupling from the axle bearing through the type of guidance is guaranteed within the pivotable pendulum 19.
- the suspension according to the invention is preferably for use with Eddy current brakes provided, within the scope of the invention In general, it is thought for rail brakes, i.e. magnetic rail brakes and eddy current brakes.
