Description

Takie usytuowanie pasów elastycznych zmniejsza do minimum moment skrecajacy na nich wystepujacy i wytwarzany przez wspóldzia¬ lanie szczek hamulcowych z powierzchniami czo¬ lowymi hamujacymi na obrotowych tarczach 20.Ponadto zmniejsza to halas i wibracje w hamulcu tarczowym, co czesto stanowi powazny problem.Nalezy podkreslic, ze elastyczne pasy zastosowa¬ ne zgodnie z wynalazkiem maja minimalne wy¬ miary i sa tak ustawione, ze lacza sie scisle z roz¬ mieszczonymi powierzchniami na siodle 52 i ply¬ cie 26 przenoszacej moment, zmniejszajac przez to ilosc materialu potrzebnego na ich wykonanie.Fakt, ze dwa splaszczone konce elastycznych pa¬ sów sa umieszczone w plaszczyznach, które sa umieszczone blisko siebie w kierunku osiowym, powoduje równiez zmniejszenie skrecania ela¬ stycznych pasów, wywolanego przez wystepowanie momentu skrecajacego w czasie hamowania. PL PLSuch an arrangement of the elastic belts minimizes the twisting moment occurring thereon and generated by the interaction of the brake shoes with the braking faces on the rotating discs 20. In addition, it reduces noise and vibration in the disc brake, which is often a serious problem. that the elastic belts used in accordance with the invention are of minimal size and are arranged so that they engage closely with the spaced surfaces on the saddle 52 and the torque-transmitting plate 26, thereby reducing the amount of material needed to make them. The fact that the two flattened ends of the elastic belts are arranged in planes which are positioned closely together in the axial direction also reduces the twisting of the elastic belts induced by the occurrence of twisting moment during braking.

Claims

1. Claims 1. Disc brake comprising a stationary torque transmitting element, a saddle prevented from turning by a stationary element, a hydraulic actuator adapted to be positioned on one side of the disc, a reaction part adapted to be positioned on the other sides of the disc, the first brake shoe actuated by a hydraulic cylinder, the second brake shoe adapted to be positioned between the disc and the reaction section and actuated by the reaction section, a torque transfer plate positioned between the hydraulic cylinder, the jaws and the disc, and the actuator has a pair of flanges extending outwardly, elastic belts for holding the saddle on a stationary torque transmission plate, characterized in that the first flexible belt (74) is attached with its flattened end (79) to the arm (34) of the stationary torque transmission plate (26) and with its other end to the surface of the flange (86) of the hydraulic cylinder (54) of the fifth wheel 52 and the other end The top belt (76) is attached with its flattened end (78) to the arm (36) of the torque transmitting plate and with its other end to the flange (88) of the hydraulic cylinder (54) such that the pivots of each elastic belt (74, 76) be in a vertical line to prevent travel of the saddle (52) relative to the torque transmission plate.

4. Disc brake according to claim 3. The method of claim 3, characterized in that the fixed element (32) comprises a torque transmitting plate (26) positioned substantially parallel to the plane of rotation of the disc (20) and a pair of spaced-apart flanges (86, 88) on the hydraulic actuator (54). ) is integral with the body and projecting axially inward from the body, the torque transmitting plate (26).

5. Disc brake according to claim 4. The method of claim 4, characterized in that the brake shoe (100, 106) has outwardly facing leading edges and the flanges (86, 88) have inwardly facing front surfaces interacting with the outwardly facing leading edges on the brake shoe. 15 23 25 89 35 40 45 50 55 6066901
