Pivot joint connecting brake head to brake beam

Abstract

The invention is a center rotation connector for connecting brake head and brake beam of the railway carriage. It permits the brake head to regulate the radial and sideways direction with controllable rotation degree, makes the brake shoe adaptive to the frame of the wheel, thus brake shoe can reach to enough force distribution, and the utilization of the brake shoe material can be optimized.

Description

Technical field [0001] The present invention relates to a brake head assembly used in a brake beam of a railway carriage, and in particular to a pivot joint that pivotally connects the brake head of a railway carriage and the brake beam. Sufficient force transmission of the tiles, and sufficient contact between the brake shoes and the wheels of the railway car bogie. Background technique [0002] Most railway freight cars use a mechanism called a brake device, which is generally classified as a body mounting system (BMS, the actuator is installed on the platform of the car), and a direct acting truck mounting system (TMS-DA, causing The actuator is installed on the beam) or the indirect action truck mounting system (TMS-IA, the actuator is installed on the truck, and the lever acts on the standard brake beam). [0003] Generally, an air tank that supplies compressed air to the brake cylinder is installed on the car body. In a BMS, the brake cylinder provides mechanical force to a...

Problems solved by technology

In addition, during braking operation, since the fixed connection points are located between the brake beam and its extension of the wagon guide, between the brake head and the wheel during braking operation, and between the brake head and the brake Between the beams, there is a double constraint that somehow buckles the displacement of the beams within the wagon guides and self-aligns towards the center of the wheel so that the force applied through the brake head does not spread evenly along the brake shoe Conveyance, thereby, produces uneven and incomplete wear of the useful material of the brake shoe, which is a waste of useful material that could otherwise be properly used, therefore, the brake shoe material must be replaced frequently, which is a waste of time and money kind of waste

In many cases, this uneven taper wear leaves a brake shoe material where the bottom of the shoe is like new and the top has reached the limit of its use, resulting in 50% material waste

[0008] In extreme cases, the wear of the brake shoe material at some point has caused the metal of the brake shoe frame to contact the corresponding bogie wheel, causing damage to both the brake shoe frame and the wheel

[0009] It is also a common problem that, as the carriage exhausts its cycle life, the parts of its brakes gradually wear out, the sagging and buckling of the beam as described above becomes severe, and as a result, as the vehicle The aging of the brake shoe further shortens the service life of the brake shoe
