Disk brake mechanisms - the general information

The principle of functioning of disk brake mechanisms is extremely simple: at squeezing of a pedal of a foot brake made brake disk rigidly jointed with wheel assemblage of pig-iron is densely clamped between two equipped frictional overlays колодками. Modern brake disks have a ventilated design, that appreciably raises efficiency of a heat-conducting path from assemblage and prevents a dangerous overheat of components. Arising during wheel rotation centrifugal force reliably protects working surfaces of a disk from formation on them of any sort of mud adjournment that guarantees uniformity of a clip колодок, providing smoothness of braking of a vehicle.

Adjustment of disk brake mechanisms is made automatically and put in pawn in an assemblage design. Distinguish three various types of disk brake mechanisms:

· With the fixed support;
· With a sliding support;
· With floating скобой.

The fixed supports have a two-cylinder design in which two separate pistons press frictional колодки to both parties of a brake disk. Actually the support case is thus established rigidly and absolutely motionless.

Mechanisms with a sliding support and floating скобой by an action principle practically do not differ from each other, - in both designs internal колодка the support case / floating скоба, in this case rigidly not fixed nestles on a brake disk hydraulic effort, thus actually, is slightly displaced in an opposite direction, the return end pressing the second колодку to disk lateral aspect. Various ways of fastening of a similar sort of supports can be used, - some are equipped located from above or from below assemblages by an axis, on others as directing slidings fixing bolts are used.
