Abstract: A brake shoe has a groove in a support member to receive a dove-tail guide on a brake lining to hold the brake lining on the support member. One longitudinal side of the groove is inclined to define a wedge and the other longitudinal side is straight. Springs are mounted on the support member on the straight side of the groove to extend behind and clamp the brake lining dove-tail guide. Modifications of the groove include inclined sides along only portions of the groove and springs at the straight wall portions of the groove to extend behind and clamp the dove-tail guide of the brake lining.

Abstract: A brake disc for disc brakes on rail vehicles comprises an intermediate member connected to the inner peripheral surface of an annular element. The intermediate member is spaced radially from a hub and there are a pair of radially opposed annular grooves in the hub and intermediate member with blocks of resilient material in the opposed grooves. The blocks are pre-stressed and completely occupy the widths of the grooves. Heat inhibiting material is provided for inhibiting heat flow from the annular braking element to the resilient blocks.

Abstract: In a railway vehicle having two brake discs on the axle of a wheel and axle assembly a disc brake comprises brake shoes on opposite faces of each brake disc and the brake shoes being suspended from the bogie frame. For each brake disc there is a pair of brake levers pivotally connected by pull-rod means with the inner ends of the brake levers being pivotally connected to the brake shoes. One of the remote ends of the outer brake levers is pivotally connected to a displaceably supported brake cylinder and the remote end of the other outer brake lever is pivotally connected to a piston rod extending from the brake cylinder. The remote ends of the two central brake levers are both pivotally connected to fixed points.

Abstract: A brake disc for railway vehicle disc brakes that can be operated in both directions of rotation has a friction ring traversed by radial cooling ducts formed by a plurality of ribs. A radial impeller is mounted in the space radially inwardly of the friction ring and the impeller has an axial intake and a radial outlet directed toward the cooling air ducts. A plurality of radially oriented blades are provided on the impeller between the intake and outlet.

Abstract: A brake disc for disc brakes for vehicles comprises a brake disc annular element mounted on a hub. The annular element and hub are interconnected by a plurality of clamping sleeves seated in radially opposed bores in the hub and annular element. Each clamping sleeve comprises two sleeves disposed co-axially one within the other and each sleeve has an axially directed slot therein with the slots being offset 180.degree..
