Filed: 1925-04-03
Abstract: 250,750. Clark, D'A. M., (Bendix Brake Co.). April 3, 1925. Compensating for wear; force-transmitting mechanism.-In a, steering-wheel brake wherein a universal joint is provided between the cam shaft 42, Fig. 1, and the brake-operating rockshaft 58, the latter is slidably mounted in a sleeve 88 carrying part spherical members 90, 9B which slidably engage a member 92 supported on the chassis frame 16, a spring 100, reaching between the member 96 and a disc 98 carried by the sleeve, serving to hold the members 90, 96 in position. The hollow cam shaft 42 is supported in a cylindrical bore in a bearing 46, a part spherical member 64 on which is engaged by part spherical members 66, 68, carried by the shaft 58 and held in position by a spring 70. The inner end of the shaft 58 is rounded and flattened, and is pivotally mounted by a pin 60, Fig. 2, in upper and lower members 62 having inner Hat surfaces to engage the flattened ends of the shaft, and cylindrical outer surfaces to engage a cylindrical cross-bore in the cam shaft 42. When the joint is assembled, the members 62 are held in place by the bore in the support 46, and axial displacement of the pin is prevented by the cross-bore in the shaft 42. Since the axis of the pin, which is normally vertical, intersects at an acute angle the axis of the steering pivot, the brake on the outer front wheel will be eased when rounding a corner. As shown in Fig. 3, the brake-operating arm 74 is clamped on the shaft 58, which is fluted, and has at its lower end a part spherical bearing 82 to receive a member 76 held on the pull rod 80 by a nut 78, the arm 74 being held against the member 76 by a spring 84.
