Described navigation system is a kind of passive side clearance compensation mechanism, form by set screw, bearing pin, antifriction alloy bearing shell, opening sleeve and positioning plate, positioning plate is fixed on the hollow shaft and with the opening sleeve screw and is connected, the antifriction alloy bearing shell is arranged in the opening sleeve, wherein adorn bearing pin, produce slide relative between bearing pin and opening sleeve and the antifriction alloy bearing shell, thereby keep passive side brake clearance constant.
Compared with prior art, advantage of the present invention is apparent, mainly shows:
1. streamlined appearance, integrated form oil cylinder effectively reduce the break volume, save installing space;
2. stiffening rib and rhombus carriage are strengthened braking force zone of action rigidity, reduce distortion; Compared with similar products, brake structural intensity is slightly excellent, and distortion reduces 20%;
3. rhombus braking plate area of contact is big, can adapt to the distortion of braking body better.The braking plate wearing and tearing are even, and long service life prolongs maintenance, replacement cycle;
4. the breach of quick replacable type is cut cotter pilotage and is made that to change braking plate more convenient, and Fig. 7, Fig. 8 are its topology view.
5. use high-strength bolt connect initiatively with by moving caliper, strengthen stability of structure; Hollow shaft cooperates installation with the stud assembly break integral body to be pressed on the main frame, improves the break torsional rigidity, has reduced the base size.
6. increased braking plate and brake disc assemblage gap, easy to adjust.
