Abstract:
A spring applied brake assembly for a railway vehicle braking system, such railway vehicle braking system including a force transfer lever and at least one force transmitting member for initiating a brake application, said spring applied brake assembly comprising:(a) a casing engageable with such railway vehicle braking system; (b) a piston assembly positioned within and mounted for longitudinal movement within said casing; (c) a piston rod secured to a first end of said piston assembly and capable of extending through an opening in a first end of said casing; (d) a spring member disposed in said casing and caged between an inner surface of a second end of said casing and a second end of said piston assembly, said spring member being capable of exerting a force against said piston assembly upon a release of said spring member causing longitudinal movement of said piston assembly within said casing causing said piston rod to extend out through said opening in said casing; (e) an extension piece attached to said force transfer lever; and (f) an attachment means for associating said piston rod with such force transfer lever extension piece such that longitudinal movement of said piston assembly in a first direction causes said piston to extend out from said opening and cause such force transfer lever to rotate and apply a force to such at least one force transmitting member for initiating a brake application.
