<p>1,213,896. Disc brakes; slack adjusters. SOC. ANON. AUTOMOBILES CITROEN. 24 Sept., 1968 [25 Sept., 1967], No. 45373/68. Heading F2E. In a disc brake having two friction elements 5 which are guided on a stationary frame and which are actuated, each, by a primary lever 3 moved by a piston 20 and by a secondary lever 4 moved by a sheathed cable 26, the primary levers are pivoted at 13 to the brake frame and are each provided with a device 15, 16, 17 for taking up play to limit their unclamping stroke and the secondary levers are pivoted at 14 to respective primary levers such that during the clamping stroke of the secondary levers they tend by reaction to move the primary levers in their unclamping direction, which, due to the limitation imposed on this stroke by the play taking up devices, ensures for each secondary lever a practically fixed pivot. Preferably, the ends of the primary levers to which the secondary levers are pivoted are forked and the ends of the secondary levers are sandwiched between the forks. Automatic slack adjusters.-Each device for taking up play comprises a toothed sector 15 on one end of the respective primary lever and a co-operating toothed member 16 urged towards the sector by a spring 17.</p> |
