MULTIPLE DISK CLUTCH OR BRAKE OF AUTOMATIC TRANSMISSION

摘要

PURPOSE:To prevent the generation of continual shock sound by providing plate springs for energizing and supporting outer thin disks upward at the lowest part of a ring formed gap formed between the outer thin disks and a gear box. CONSTITUTION:A band formed plate spring 51 is fixed on the lowest part of a gear box 1 after being inserted through a ring formed gap formed by the outer peripheral surfaces of the respective outer thin disks 38, 32 of a multiple disk brake (B2) 37 and a multiple disk brake (B3) 31 and the inner peripheral surface of the gear box 1. As a result, the outer thin disks 38, 32 are constantly positioned above by the action of the plate spring 51 so as to prevent the shake between the outer thin disks 38, 32 and the gear box 1. As a result, the outer thin disks are prevented from being dragged in a rotational motion so as to prevent the generation of continual shock sound.
