摘要:
A method of mounting a plurality of brake blocks (10, 12) in circumferential alignment with one another and in opposed relationship to a peripheral surface (14) of a member (16) which is rotatable about an axis (18) so that the blocks can be moved simultaneously into engagement with said peripheral surface to apply a braking force to the member. The method comprises mounting the blocks (10, 12) on a common holder (20) which is mounted in opposed relationship to said peripheral surface (14) and is movable towards and away from said peripheral surface. The method also comprises providing at least one of said brake blocks (10, 12) with one or more projections (10e, 12e) arranged to prevent mounting of one or more of the blocks on the holder unless the blocks are arranged in a desired orientation.

The invention relates to a braking body, especially a brake pad or a disc-brake pad, comprising a supporting body (7) with recesses (11, 44, 62, 102) in which elements consisting of friction material (9, 27, 50, 68, 104) are located. The invention is characterised in that said friction material elements (9, 27, 50, 68, 104) are mounted in such a way that they can move in the longitudinal direction of the recesses (11, 44, 62, 102). The mounting is configured in such a way that it is elastic or can tilt in the direction of the recesses (11, 44, 62, 102) and the friction material elements (9, 27, 50, 68, 104) form a friction surface (1) with the supporting body (7).

A braking device for the bar supporting the roll of paper or the like in printers. The device is applicable to a bar for supporting a roll of paper or other print medium and comprises, arranged at one end of the bar carrying the roll of paper or print medium, a hub (18) with a stainless steel casing which is acted on by at least one pair of braking shoes (6,20) disposed in diametrally opposed positions on the hub and acted on by opposing springs (30,31) in a transverse arrangement whereas, at the opposite end, the bar carrying the print roll is acted on solely by the axial effort of a spring incorporated in the housing of the end of the said bar.

A tread conditioning unit for applying a brake block (3) against the tread of a rail vehicle wheel comprises a pneumatic cylinder (1) having a piston (9) with a piston rod (11). A block holder (2) for the brake block is pivotably connected to the piston rod by means comprising a pivot sleeve (19) rotatably attached in the end of the piston rod facing the block holder, which is provided with a circular surface (25) for engagement with the pivot sleeve, means (20, 22, 23) being provided for keeping the block holder connected to the pivot sleeve.
摘要:
Der Rücken (1) und der Bremskörper (4) der Bremsklotzsohle sind beide als Gusskörper ausgebildet. Diese vorwiegend aus Gussteilen bestehende Bremssohle kann besonders rationell durch Giessvorgänge oder Verbundguss in ein und derselben Giessform hergestellt werden. Die Giessform wird dabei durch ein Stahlblech in Giessräume für den Rücken (1) bzw. den Bremskörper (4) unterteilt. Es können auch Armierungen aus Stahl eingegossen werden.
