SU128313A1 - Brake cylinder with automatic adjustment of the gap between the pads and the brake drum in brake systems with hydraulic drive - Google Patents

Description

Known brake cylinders with automatic adjustment of the gap between the pads and the brake drum in brake systems with hydraulic irivodom containing cylinders, norshni and stop rings. However, such cylinders do not ensure the preservation of the standing gap between the pads and the brake drum.

In the drawable device, this disadvantage is eliminated by the fact that the stop rings are made split and planted in cylinders so that the force required for their movement is less than the force developed by the pistons during braking and more force of the reverse springs. In this case, the pistons are made with protrusions interacting with split rings installed with a given clearance relative to them.

FIG. Figure 1 shows one of the embodiments of the brake cylinder, on the side; in fig. 2 - cylinder in cross section.

The brake cylinder is designed to move the shoes L mounted on disk 2 and retractable with spring springs 3.

The Corsus 4 cylinder is fixed on the disk 2 and provided with grooves for holding the cuffs 5. Each of the two pistons b has slots for the stop 7, a recess for the sealing ring 8 and a shank with a collar 9. A split retaining ring 10 is also seated, which also has a collar //, and the mutual axial movement of the ring 10 and the piston 6 is possible within the gap and between the shoulders 9 and //. The split rings W are compressed when they fit into the housing 4, and their rigidity and iodine size are selected in such a way that the force required to move them is less than the force developed by the pistons 6 during braking and the force of the reverse springs 3 is not.
