Device and Operating Principle

The brake rigging lever transmission regulator consists of a housing, a ratchet mechanism, a lever system, a spring block, and a self-adjusting mechanism that activates when a predetermined backlash threshold is exceeded. During operation, the regulator automatically compensates for excessive brake cylinder stroke resulting from brake shoe wear, maintaining the required clearance between the brake shoes and the wheels.

The operating principle is based on converting the linear motion of the brake rigging rods into rotational motion of the ratchet mechanism. When a specified rotation angle is reached, the ratchet mechanism shifts the adjustment unit, reducing the length of the lever transmission. This ensures optimal performance of the wagon brake system under various operating conditions.

Purpose

Using the RГВП-675T (RTRP-675T) regulator allows to:

• provide automatic adjustment of the brake lever transmission during operation;

• reduce wear of brake equipment;

• increase braking efficiency and reliability;

• eliminate the need for periodic manual adjustment;

• reduce maintenance costs of rolling stock.

Compliance

The regulators comply with:

• DSTU GOST 33223:2016 (GOST 33223-2015, IDT) — Railway rolling stock brake systems. Automatic pressure-regulating devices in the power pneumatic actuator. Safety requirements and test methods;

• TU U 35.2-05486734-001:2007 — Brake Lever Transmission Regulator RГВП-675T (RTRP-675T). Technical Specifications.
