Definitions
- the invention relates to a magnetic braking device for Rail vehicles with a bogie, between the axles above the rails each have a lifting and lowering support for those held therein Brake magnet is arranged, each carrier end arm which, when the carrier is lowered, has support shoes support the associated thrust bearings of the bogie.
- Such a braking device in the form of an eddy current braking device is known (DE 26 14 298).
- the carrier with the brake magnet is on the Lifting cylinder supported bogie can be raised and lowered.
- the carrier is lowered with the brake magnets, until the support shoes of its end arms are on the thrust bearings support.
- the brake magnets are at a distance of 3 to 10 mm, typically approx. 7 mm, above the rail surface.
- the Brake magnets interact with the rail and thus generate a braking force without wear.
- magnetic rail brakes are known (DE-GM 18 64 750), at which the brake magnets are lowered down to the rail, so that a braking friction occurs.
- the object of the invention is to provide a magnetic braking device, which is both an eddy current braking operation and one Magnetic rail brake operation enabled.
- the overlay shoe has a in the area his boom arranged lever gear with an actuator is connected and thus essentially perpendicular to the plane of the rails is adjustable.
- one Lever gear can adjust the position of the pads to theirs Booms are changed so that for eddy current braking lowered carrier with its brake magnets beyond is lowered until the brake magnets rest on the rail.
- degrees of freedom in the movement of the wearer Expedient if the support shoe is perpendicular to the backdrop of the boom Rail level is guided.
- the movement of the lever and thus the in its Controlled led shoe controls also work essentially vertical forces that occur during braking.
- control surface can have a stop for the roller, wherein the stop is arranged so that the for Eddy current braking operation provided position of the pad shoe the axis the role between the stop and the direction of that of the pad transferred power is.
- This is the one for eddy current braking
- the intended position of the support shoe is practically locked.
- the lock can be canceled by actuating the actuating device.
- the adjusting device preferably grips the associated arm of the Lever on and is the joint with a hinge pin in a backdrop of the Outrigger led. This arrangement improves and ensures the leadership of the Lever and thus the support shoe when actuating the actuating device.
- the actuator itself can be pivoted on the boom or on the carrier be mounted lifting cylinder, which led out on a housing Piston rod articulates on the associated arm of the lever. At Pressurizing the cylinder will cause the lever to act on it Guided tours on the one hand between the role and control surface and on the other hand between the hinge pin and the associated backdrop so that the Pad shoe is raised or lowered in its associated setting.
- the piston rod is preferably on the housing via a compression spring supported.
- This compression spring serves on the one hand as an additional safeguard when Eddy current brake operation because it has the role on the assigned stop of the Boom and thus the lever and the support shoe in the for the Eddy current braking operation holds the intended position.
- the compression spring should on the other hand, it should also be designed so that it is able Magnetic rail brake operation with levers positioned in the for Eddy current braking operation attributed to certain position and the Lift the carrier with the brake magnet off the rail, so that at Failure of a control signal and / or the power supply of the Actuator the brake is free from the rail. That is also ensures that a parked or defective rail vehicle moves can be.
- a carrier 1 which can be raised and lowered by means of a lifting cylinder for not held therein brake magnets shown is arranged.
- Each carrier 1 has ends Boom 2, which is in the direction of the rails lowered beam 1 with support shoes 3 on associated thrust bearings 4 of the bogie support.
- the thrust bearing 4 can be below the wheel axles of the bogie be arranged.
- the arms 2 have side plates 5 with in the direction of the rails shown open slots 6, which are in the illustrated Extend the version vertically and as a backdrop for the pins 7 the support shoes 3 serve (Fig. 3).
- the support shoes 3 are each between two identical two-armed Levers 8 arranged and pivotally mounted on an arm 9 of the lever 8.
- An actuating device 11 engages on the other arms 10 of the lever 8.
- a roller 12 is mounted on a control surface 13 of an insert 14 End of the respective boom 2 is assigned.
- the control surface 13 includes a trained on the insert 14, in the substantially vertically extending stop 15 on which the roller 12 in the Fig. 1 reproduced functional position (eddy current braking operation) is present.
- the stop 15 is arranged in such a way that for eddy current braking operation intended position of the support shoe 3, the axis 16 of the roller 12 between the stop 15 and the direction 17 of the shoe 3 to transferred power is.
- the adjusting device is on the other arms 10 of the two identical levers 8 11 articulated.
- the hinge is formed by a hinge pin 18, the ends 19 in slots 20 serving as a backdrop in the Side plates 5 of the boom 2 are guided (Fig. 2,3).
- the slots 20 are in the embodiment shown curved in a circular arc, the Center of curvature approximately in the area of the support shoe 3 or its Pin 7 is located.
- the actuating device 11 includes a pneumatically actuated lifting cylinder 21 which in the embodiment shown is pivotally mounted on the carrier 1 and a has piston rod 23 led out of its housing 22.
- the Piston rod 23 is between the two lifts 8 on the hinge pin 18 stored. Furthermore, the piston rod 23 has an abutment 24 for one Compression spring 25, the other end of which is supported on the housing 22.
- the magnetic braking device shown enables both Eddy current brake operation as well as a magnetic rail brake operation.
- the magnetic braking device is not inactive with the help of shown, attacking the carrier 1 lifting cylinder, also the support shoes 3 are lifted from their thrust bearings 4.
- the magnetic braking device is used for eddy current braking lowered until it assumes the functional position shown in FIG. 1, in which the support shoes 3 are on their assigned pressure plates 4 support. Then there are those arranged in or on the carrier 1 Brake magnets about 7 mm above the upper edge of the not shown Rails.
- the compression spring 25 is designed so that when the pressure in the lifting cylinder is reduced 21 their force is sufficient to lift the carrier 1 with the brake magnet 2 and the lever 8 in the locked operating position according to FIG. 1 attributed.
- the compression spring 25 supports the locking.
