- Fig. 3 shows an interior view of the bearing block 4 with Bearing housing 19 for receiving the bearing 16.
- Eyelets 20 visible on which the brake 7 is mounted.
- the Support surface for the upper bridge 8 is 21 and the Aufläge vom for the lateral webs 9 are 22 designated, wherein the webs 8.9 with the bearing block 4 or can be screwed with the motor stand 3, for example.
- the evacuation drive consists of a motor 23 with pinion 24, wherein in evacuation operation, the pinion 24 in the Sprocket 18 engages and the traction sheave 5 in motion added.
- Fig. 4 shows the upper web 8, the box-shaped is formed and the bearing surface 8.1 on the Support surface 21 fits.
- Fig. 5 shows the lateral web 9, the wedge-shaped is formed and the bearing surface 9.1 on the Support surface 22 fits.
- Fig. 6 and Fig. 7 show the bearing block 4 on each side arranged brake 7 of the drive unit 1, wherein a Brake caliper 30 to the eyelets 20 penetrating axes 31st is floating.
- the caliper 30 may be at the most adjustable by means of adjusting screws 32 Move distance d, wherein each axis 31 a spring 33rd provided, the caliper 30 in the direction of traction sheave 5 charged.
- the axes 31 are at one with the Bearing 4 related support bracket 34 fixed.
- the caliper 30 carries the drive pulley side, inner brake shoe 40 and serves as Support for spacer tubes 35 and threaded rods 36, the a support plate 37 for a hydraulic, for example Hold actuator 38.
- Compression springs 39 is supported at one end to the support plate 37 and at the other end to a Pressure plate 41 from which guided by means of the caliper 30 Bolt 42 the spring force of the compression springs 39 on the outside Transfer brake shoe 43.
- Bolt 42 the spring force of the compression springs 39 on the outside Transfer brake shoe 43.
- the activated actuator 38 acts the activated actuator 38 by means of a pull rod 44 the pressure plate 41 and raises the spring force of the coaxial Pull rod 44 arranged compression springs 39 on the outer Brake shoe 43 on.
- the caliper 30 moves due to the spring force of the spring 33 in the direction Traction sheave 5, wherein the inner brake shoe 40 of the Brake disc 17 is moved away.
