Title: Automatic brake adjuster
IPC: F16D65/56
Filed: 1962-05-17
Abstract: 940,864. Automatic brake adjusters. GENERAL MOTORS CORPORATION. May 17, 1962 [Aug. 3, 1961], No. 19046/62. Heading F2E. An internal shoe-drum brake has a composite lever system 50, 60 pivoted at 42 on the shoe 13 and normally urged to rotate as a unit to adjust a strut 30 positioned between the shoe ends when the shoes 12, 13 are urged by means 36 to engage the drum 11 but articulating, when the braking force exceeds a predetermined value to avoid overstressing the system. As shown a rigid link 70 connects a bracket 25 positioned on an anchor pin 20 to the stem portion of the T-shaped lever 60 which pivots on an ear 63 at one end of its head portion in an aperture 64 in the lever 50. An ear 66 on the other end of its head portion is engaged by a tension spring 67 the opposite end of which is hooked into a hole 168 in the lever 50 so that the ear 66 is pulled against a stop 68 and normally retains the lever 60 in a predetermined position relative to the lever 50 so that both levers function as a single lever. In normal operation of the brake the drum rotates in the direction of the arrow 90 as the vehicle moves forward. Thus, on application of the brakes, the wheel cylinder 36 expands the brakes shoes into engagement with the drum 11 to effect counter clockwise rotation of the shoe assembly with the end portion 22 of the shoe 13 engaging the anchor pin 20. On reverse movement of the vehicle and on application of the brakes the brake assembly will rotate in a clockwise direction. The lever 70 pulling on lever 60 will cause the lever 50 to rotate about its pivot 42 against the spring 56 and effect a counter clockwise movement of its end portion 55 to rotate the wheel 33 to effect an extension of the strut 30. However when a heavy brake action is occasioned the thrust on the strut 30 is sufficient to prevent relative rotation of the two threaded portions 31, 32 thereof thereby holding the wheel 33 stationary. This prevents the lever 50 from rotating in its normal manner so that the lever 60 rotates on its ear 63 against the action of spring 67 to relieve the high stresses which would otherwise be applied to the lever 50. The wheel 33 may be manually rotated by a handtool to adjust the brakes.
