- the magnetic body is inserted over the transmission input shaft and connected via bolts with the Ge ⁇ gear housing for the purpose of supporting the braking torque.
- the brake disc is rotatably mounted on the transmission input shaft. Due to the installation location of the spring-applied brakes in the transmission input shaft can satisfactory He deliver ⁇ results of despite their lower brake torque, the brake, in particular as a parking brake.
- the Brem ⁇ se has smaller dimensions than pneumatic or hydrau ⁇ metallic braking systems, working with less loss and has WE niger failure-prone components on. The problem of the low
- Braking torque is achieved in that the brake can be installed only in Be ⁇ rich the transmission input shaft and is preferably used as a parking brake.
- the brake is too weak to act directly on the braked wheel of the rail vehicle without intervening transmission. This would be desirable for braking at high speeds Ge ⁇ with short reaction times under direct close to the wheel deceleration of the moving parts to enable.
- the invention has for its object to provide a Bremsvorrich ⁇ tion, which is characterized by the achievement of a large braking force, short reaction time and small dimensions.
- This object is achieved according to the invention with the features of claim 1, in a brake assembly for rail vehicles, with an electromagnetic Federtik- brake, wherein the braking force is applied to the part to be braked by spring force and to cancel the braking force, a magnet assembly is provided, the acts against the spring force and consists of a coil assembly with anchor plate, which are movable relative to each other, wherein the movable part thereof with the acting on the part to be braked

- the magnet assembly is provided. This consists of a coil arrangement with Ankerplat- te, which are movable relative to each other, wherein the movable part is connected to the stamp.
- the movable part can be located at the end of the punch, which also acts on the spring force.
- the non-movable part of the magnet assembly is fixed to a fixed part, for example to a fixed part of the spring-applied brake.
- the coil assembly To open the brake assembly, the coil assembly must be subjected to a corresponding voltage. The resulting magnetic field pulls the anchor plate At and the movable part moves together with the Stem ⁇ pel against the spring force, so that the braking means located at the other end of the punch is moved from the part to be braked ⁇ .
- the brake assembly is now open. In the event of a power failure, the brake assembly closes automatically due to the collapsing magnetic field and the relaxing spring. This is important for safety reasons, so that the rail vehicle can be brought to a standstill in case of failure of the electrical equipment.
- the stamp enables direct introduction of forces ⁇ tung in a line of action on the part to be braked. If necessary, the stamp can transmit an increased braking force to the part of the rail vehicle to be braked.

- the stamp which protrudes only partially from the housing, can be guided through the housing.
- the Bremsanord ⁇ tion obtained by the housing a compact design.
- the Ge ⁇ housing additionally has a protective function for the components in the interior. The alignment of the components to each other can already be done during the manufacturing process of the brake assembly and not only during installation on the rail vehicle. This reduces the number of errors that can lead to conclusions Massivstö ⁇ .
- the housing may for example be formed as a hollow cylinder which is closed at its one end by a bottom and the other end is open.
- the compression spring may be fixed at one end to the ground and be supported against this and bear on its other end the stamp.

This increases the reliability of the brake assembly. Any existing leadership of the stamp is less heavily loaded. This saves on repair costs.
- a further advantageous embodiment of the invention can provide that the coil assembly and the anchor plate surround the punch annular.
- the coil assembly and the anchor plates may be formed, for example, as circular plates with a central passage for the punch. This shaping of the Spu ⁇ lena order and anchor plate reaches optimum power density for a given volume of the assembly.
- the movable part of the magnet assembly is fixed to the punch.
- the movable part may be, for example, the coil arrangement. This consists of a yoke in the form of the circular plate te, which has a circular groove in which the coil is located.
- the power supply of the coil can be done via the stamp. For example, in the interior of the stamp Lei ⁇ lines may be laid, which are guided through a hole on the punch to the coil. In order not to disturb the magnetic field by the punch when a voltage is applied to the coil, this may consist of non-magnetizable material. With appropriate external geometrical conditions, the shape of the magnet arrangement can also be selected oval.

- the coil arrangement is additionally provided on the surface facing the armature plate with a permanent magnet, wherein the latter
- Magnetic force is chosen so that it is smaller than the Fe ⁇ derkraft.
- the permanent magnet can completely or partially cover the armature-side end face of the yoke. Such attached Per ⁇ manentmagnete can be very easily connected to the yoke.
- the permanent magnet could also be mounted with a similar effect inside the yoke.
- the Permanentmag ⁇ net pulls the anchor plate in the direction of the coil assembly. Since the brake with the coil arrangement switched off, for example in the case of a power failure, with a prescribed braking force must act, the brake is equipped with a restoring force out ⁇ which is greater than the magnetic force of the Neten Permanentmag ⁇ and produces a sufficient safety prescribed braking pressure beyond. When the brake is open, the power consumption of the coil assembly can be reduced due to the permanent magnet. This saves costs.
- the design of the brake device with pure electromagnets is sufficient for the metro area in conjunction with a permanent magnet synchronous drive.
- hybrid magnets can used to ⁇ .
- An advantageous embodiment of the invention can provide that the protruding out of the housing portion of the punch is formed he ⁇ belartig.

- the number of magnet arrangements must be dimensioned according to the required braking force. Brake assemblies with different demands on their braking force can be assembled from identical components by only varying the number of magnet assemblies. This simplifies the manufacturing process and saves costs.

- the arrangement allows to apply individually to the magnet assemblies with voltage and thereby allows a continuous adjustment of the braking force.
- the diameter of the brake assembly can be reduced by the location of the Magnetan- orders.
- the housing - relative to the direction of movement of the stamp - is mounted longitudinally displaceable.
- the longitudinally displaceable mounting of the housing allows readjustment of the braking device. Due to the wear-related decrease of the brake fluid increases in closed ⁇ sene brake the length of the compression spring. This leads to a decrease in the braking force. In order to keep the braking force constant, the housing on which the compression spring is supported, can be readjusted. When the brake is open, the then force-free housing for adjustment can be particularly easily and ge ⁇ exactly moved longitudinally on the storage and fixed in the new position.
- the housing is longitudinally displaceable by means of a drive.
- the drive moves the housing with the brake open to a new position, which is determined beforehand by means of closed brake parameters.

- the drive can move the housing to the new position after opening the brake.
- the housing can be fixed in this new position by a latching mechanism or the drive supports the housing. Since forces act on the housing when the brake is closed, it is advantageous to secure it by means of an end stop. Since ⁇ a safe operation of the braking device can be ensured by the event of failure of the supporting or drive the latch.
- the Ge ⁇ housing by means of a toothed pinion is longitudinally displaceable.
- the toothed drive may for example be part of a Getriebestu ⁇ fe.
- the drive can generate the required linear movement for displacement of the housing by means of this transmission.
- any embodiments may be used, for example, linear, self-locking screw or direk ⁇ te spindle drives.
