An den Bremsbacken 27 greifen Bremshebel 28 an, die mittels ersten Betätigungsbolzen 29 von Aktuatoren 30 betätigbar sind.2 shows the gearless drive 6, for example the traction sheave 7 in a three-dimensional representation. The Drive 6 consists of a housing 15 in which a motor 16 with stator 17 and rotor 18 is arranged. One as a base 15.1 trained housing extension is used for attachment of the drive 6 on the rails 5, 5.1. One on housing 15 mounted shaft 19 transmits the rotational movement of the Rotor 18 on the traction sheave 7. The shaft 19 is by means of a first bearing 20 and a second bearing 21 on Housing 19 stored. There is a at the motor end of the shaft Pulse generator 22 arranged the rotational movement the shaft 19 measures. At the other end of the shaft is a Shaft flange 23 arranged on which the traction sheave 7th can be fastened by means of screws 24, for example. The Traction sheave 7 is a hollow cylinder closed on one side trained, the closed side with the Shaft flange 23 is connectable. On the outer surface of the jacket the traction sheave 7 are arranged rope grooves 25 which the Management of the suspension cables 8 and the power transmission from the Traction sheave 7 serve on the suspension cables 8. The Inner surface of the traction sheave 7 is a brake drum 26 formed on the actuatable brake shoes 27 the Shut down actuator 6. Grip the brake shoes 27 Brake lever 28, which by means of first actuating pin 29th can be actuated by actuators 30.

Fig. 3 zeigt einen Schnitt durch den Antrieb 6 im Bereich der Bremsbacken 27, wobei die Treibscheibe 7 nicht dargestellt ist. Die Bremsbacke 27 ist einenends an einem ersten Gehäusebolzen 31 gelenkig angeordnet und anderenends an einem Bremshebelbolzen 28.1 gelenkig mit dem Bremshebel 28 verbunden. Der Bremshebel 28 weist einen Hebelbolzen 32.1 auf, an dem ein Mitnehmer 32 angreift, wobei der Mitnehmer 32 an einer Bremsachse 33 angeordnet ist. Ausserdem ist der Bremshebel 28 mit einem ersten Betätigungsbolzen 29 verbunden. Der erste Betätigungsbolzen 29 ist mittels des Aktuators 30 betätigbar, der aus einem ersten Federpacket 34, einem am Gehäuse 15 angeordneten Magnet 35 und aus einer Ankerplatte 36 besteht.Fig. 3 shows a section through the drive 6 in the area the brake shoes 27, the traction sheave 7 not is shown. The brake shoe 27 is at one end first housing bolt 31 articulated and the other end on a brake lever pin 28.1 articulated with the brake lever 28 connected. The brake lever 28 has a lever pin 32.1 on which a driver 32 engages, the Driver 32 is arranged on a brake axle 33. In addition, the brake lever 28 with a first Actuating bolt 29 connected. The first actuating pin 29 can be actuated by means of the actuator 30, which consists of a first spring pack 34, one arranged on the housing 15 Magnet 35 and consists of an anchor plate 36.

Mit strombeaufschlagtem Magnet 35 wird die Ankerplatte 36 zum Magnet 35 hin bewegt, wobei der erste Betätigungsbolzen 29 entgegen der Federkraft bewegt wird und die Bremsbacke 27 von der Bremstrommel 26 gelöst wird. Die Bremsbacke 27 ist auch mittels des Mitnehmers 32 mechanisch fernbedienbar, wobei der an der Bremsachse 33 angeordnete Mitnehmer 32 eine Drehbewegung ausführt und dabei den Hebelbolzen 32.1 bzw. den Bremshebel 28 in eine Linearbewegung versetzt. Wie in Fig. 4 und 5 gezeigt, ist die Bremsachse 33 am Gehäuse 15 und an einem motorseitigen Schild 37 gelagert. Die Bremsachse 33 ist mittels eines Achshebels 38 drehbar, wobei die beiden Achshebel 38 an den freien Enden beispielsweise mittels eines Kabelzuges zusammenziehbar sind, wodurch die Bremse mechanisch fernbedienbar bzw. von aussen mechanisch lüftbar ist, wodurch die Auf zugskabine 2 im Notfall auf das nächste Stockwerk gefahren werden kann. With the current applied to the magnet 35, the armature plate 36 moved towards the magnet 35, the first actuating pin 29 is moved against the spring force and the brake shoe 27 is released from the brake drum 26. The brake shoe 27 is also mechanical by means of the driver 32 can be remotely controlled, the one arranged on the brake axle 33 Carrier 32 performs a rotary movement and the Lever bolt 32.1 or the brake lever 28 in one Linear movement offset. As shown in Figs. 4 and 5 the brake axis 33 on the housing 15 and on an engine side Shield 37 stored. The brake axis 33 is by means of a Axle lever 38 rotatable, the two axle levers 38 on the free ends, for example by means of a cable pull are contractible, making the brake mechanical can be remotely controlled or mechanically ventilated from the outside, whereby the elevator car 2 to the next in an emergency Floor can be driven.

Im stromlosen Zustand des Magneten 35 betätigt ein zweites, den Hauptteil der erforderlichen Bremskraft aufbringendes Federpacket 39 mittels eines zweiten Betätigungsbolzens 40 die Bremsbacke 27, wobei die Bremsbacke 27 gegen die Bremstrommel 26 gepresst und die Treibscheibe 7 festgesetzt wird. Gleichzeitig unterstützt das erste, hauptsächlich zur Bremskrafteinstellung vorgesehene Federpacket 34 die Federkraft des zweiten Federpacketes 39. Vorteilhaft bei dieser Bremseinrichtung mit zwei getrennten Federpacketen 34,39 ist, dass die Bremshauptkraft direkt in radialer Richtung auf die Bremsbacke 27 einwirkt.In the de-energized state of the magnet 35, a second, the main part of the required braking force Spring assembly 39 by means of a second actuating pin 40 the brake shoe 27, the brake shoe 27 against the Brake drum 26 pressed and the traction sheave 7 fixed becomes. At the same time supports the first, mainly for Brake force setting provided spring package 34 die Spring force of the second spring package 39. Advantageous at this braking device with two separate spring packs 34.39 is that the main braking force is radial Direction acts on the brake shoe 27.

Wie in den Fig. 1 bis 5 gezeigt, ist die Bremseinrichtung symmetrisch aufgebaut. Je Bremsbacke 27 ist ein Bremshebel 28, ein Mitnehmer 32, eine Bremsachse 33, ein Achshebel 38, ein erster Betätigungsbolzen 29 und ein Aktuator 30 vorgesehen.As shown in FIGS. 1 to 5, the braking device constructed symmetrically. There is one brake lever per brake shoe 27 28, a driver 32, a brake axle 33, an axle lever 38, a first actuating pin 29 and an actuator 30 intended.
