BRAKE REGULATOR
KEY GEAR RGVP-300T
Brake lever gear regulator RGVP-675T (RTRP-300T) - is designed to automatically ensure constant tension of the brake levers connecting the brake cylinder with the brake pads. The presence of the regulator eliminates the need for manual adjustment of the brake lever gear after wear of the brake pads or other changes in the gear geometry.
The RGVP-675T (RTRP-675T) regulator is installed on freight cars between the rods of the brake lever transmission.
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 caused by brake shoe wear, ensuring 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, which—upon reaching a specified rotation angle—repositions the adjustment unit and shortens the lever transmission length. This ensures optimal performance of the wagon brake system under various operating conditions.
Purpose
The use of the RГВП-675T (RTRP-675T) regulator allows:
-
automatic adjustment of the brake lever transmission during operation;
-
reduction of brake equipment wear;
-
increased braking efficiency and reliability;
-
elimination of the need for periodic manual adjustment;
-
reduced maintenance costs for rolling stock.
Compliance
The regulators comply with:
-
DSTU GOST 33223:2016 (GOST 33223-2015, IDT) — Railway rolling stock brake systems. Automatic regulators of pressure in the power pneumatic actuator. Safety requirements and test methods;
