Vehicle piece 24 it is of different size, three brake slots 27 width it is also not identical, wider ring-shaped brake piece 24 is introduced into corresponding brake
In recessing 27, then remaining ring-shaped brake piece 24 is sequentially entered, and plays the role of braking step by step, to guarantee the present apparatus
It while being able to carry out normal braking, can indirectly extend the service life of ring-shaped brake piece 24, pass through three ring-shaped brakes
24 Decentralized Friction power of piece achievees the effect that improve present apparatus service life, and works as because of ring-shaped brake piece 24 and brake slot 27
When generating friction, the reaction force of generation can carry out dispersion decrease by the elastic force of elastomer 37 in cavity 36, to ensure that solid
Determine the stabilization of ring 22 Yu 23 junction of buffer disc, can preferably complete fixed work.
When the maintenance of progress ring-shaped brake piece 24 and brake disc 26, as shown in Fig. 1, first by generator 3
Disassembly rotates the caging bolt 29 in first rotating shaft 4, is moved to the left in this way together with first rotating shaft 4, at this time first rotating shaft 4 and connection
Axis device 19 separates；When one end of first rotating shaft 4 is separated with brake disc 26, at this time 25 side wall of stop collar just with 20 side wall of sleeve
Fitting, when stop collar 25, are fixed in shaft 4, when shaft 4 is moved to the left together with motor, will make stop collar 25 into
Enter between multiple buffer discs 23 and be bonded with sleeve 20, start threephase asynchronous machine 16, is driven and risen by the rotation of threaded rod 14
Drop plate 12 moves up, and brake disc 26 is pulled out brake box 5 by service ports 18 by fixed link 17 and snap ring 28 and is repaired,
Simple and convenient, it is time saving and energy saving to operate, and solves the problems, such as that traditional maintenance is inconvenient, to keep the present apparatus more practical.
