Embodiment Construction

[0020] Direction and orientation herein may refer to the normal orientation of a railway vehicle in use. Thus, unless the context clearly requires otherwise, a "longitudinal" axis or direction is parallel to the guide rail and in the direction of movement of a rail vehicle on the track in either direction. A "transverse" or "lateral" axis or direction is in a horizontal plane perpendicular to the longitudinal axis and rail. Individual components of the braking system may also have a length and a "longitudinal axis", a width and a "lateral axis". Thus, for example, a brake lever oriented substantially in line with a transversely mounted brake beam has its own longitudinal axis, which may be almost perpendicular to the longitudinal axis of the railway vehicle. The term "inboard" means toward the center of the vehicle, and may mean inboard in a longitudinal direction, a lateral direction, or both. Similarly, "outboard" means away from the center of the vehicle. "Vertical" is a...

Abstract

A truck mounted braking system is provided with a mechanical pivot adjustment on a lever connected to the brake actuator to permit the braking force applied to the wheels to vary depending on the lading condition of the car, without involving additional pneumatic elements such as a pneumatic empty load device. The system adjusts the braking force applied when the hand brake is activated, even whenthe railway car is disconnected from the pneumatic brake line.

Description

technical field [0001] This invention relates to braking systems for railway vehicles and improvements thereto, and in particular to bogie mounted braking systems. Background technique [0002] Conventional railroad car trucks used for decades in North America are three-piece trucks that include a pair of parallel side frames oriented longitudinally and connected by transversely mounted bolsters. The bolsters are supported on the side frames by spring sets. The wheelsets of the bogie are received in bearing adapters arranged in the front and rear base jaws of the side frames. The rail car is mounted on the center plate of the bolster, which allows the truck to pivot relative to the car. [0003] The braking system of a railway vehicle transmits force from a pneumatic or hydraulic actuator to cause the brake shoes to be applied against the wheels. Such systems may include "basic" rigging, which allows the components to be distributed over the railcar, or alternatively, suc...
