Title: Improvements in or relating to vehicle brakes
IPC: B60T11/04
Filed: 1927-08-10
Abstract: 285,321. Clark, D'A. M., (Bendix Brake Co.). Aug. 10, 1927. Compensating for wear.-A vehicle brake comprises a brake-applying device or cam 40, Fig. 2, a stop, which may be one side of a notch 54, Fig. 3, in a support 56, for determining the idle position of the cam and means, such as a projection 52 from the cam, for shifting the stop automatically to maintain a uniform distance of brake-applying movement of the device as the brake wears. The brake-operating lever 76 is adjusted automatically on the cam shaft 66 to compensate for the displaced position of the stop. The support 56 forms a bush for the cam-shaft 66 and is secured frictionally to the back-plate 24 of the brake drum by a nut 62. The notch 54 in the support allows " lost-motion " for the projection 52 on the cam which determines the releasing movement of the brake. When the brake shoes wear. the cam, in order to follow up the movement, turns the support 56 by means of the projection 52. This movement tends to alter the relative position of the brake lever 76 which is fixed slidably by means of inclined splines 74 to a sleeve 70 on the cam-shaft so that as the sleeve is rotated by the pins 64 it turns slightly in the boss of the lever 76 to followup the movement of the support 56. A spring 82 assists the turning movement of the sleeve 70 in the boss of the brake lever 76, the latter being prevented from lateral movement by a stop 78 working between lugs on a bracket 80. In a modification the brake lever is connected directly to the camshaft by splines, the shaft being supported by spherical bearings on the chassis and back-plate respectively.
