<p>1,158,226. Automatic slack adjusters for disc brakes. ALFRED TEVES G.m.b.H. 26 Oct., 1967 [27 Jan., 1967], No. 48689/67. Headings F2E and F2F. In a floating caliper disc brake operable alternatively by a piston assembly 12, 1 and a lever 3, the lever is located in the piston assembly and bears on one side against the end of the assembly and on the other against a pin which is screw threaded to the caliper, the arrangement being such that rotation of the lever operates the brakes and through a ratchet and pawl can rotate the pin to take up the slack. As shown, rotation of the lever advances the piston by means of a ball and ramp arrangement. The lever, on its right hand face, is formed with teeth 10 (Fig. 4) and the pin carries a disc 9 having two bent up arms 9a (Fig. 2) which act as pawls so that if rotation of the lever is sufficient to advance the pawl to the next tooth the reverse rotation on release of the brake screws out the pin to take up the slack. The brake pad assembly 13 is secured to the piston assembly and the float of the caliper necessary to apply the indirectly operated pad to the disc may result from resilience of the housing.</p> |
