ABSTRACT:
A rail car brake system of high mechanical efficiency which is compact, light in weight and economical in that it utilizes mass produced highway truck brake cylinders and slack adjusters and is easy to maintain. Critical components are lubricated and fully sealed against foreign particles. The brake system includes a shoe which is mounted in a brake head to operate in a direction truly perpendicular to the wheel tread to reduce wear, employs a long-lead screw operatively inter-connecting the brake cylinder and brake head via an automatic slack adjuster and an anti-friction roller bearing supporting the screw whereby direct load path absorption of the brake application forces is effected. The brake system also includes a parking brake which is automatically applied and released and which also provides emergency braking capability should the service brake fail. Each brake system operates on one wheel.
