<p>PURPOSE:To adjust step-in force by forming a link extensible and contractible in the lengthwise direction of a brake mechanism so that assist servo ratio of the brake can be changed in a condition that the brake is built in a case. CONSTITUTION:In a brake mechanism for actuated by pressing a wet multidisk brake plate, the brake mechanism is constituted of an extensible/contractible link 20 with one end fixed to a case 1, extensible/contractible link 4, extensible/ contractible link 21 for connecting the two links and a rod 11 for connecting the extensible/contractible link 4 to a rotary cam 12. In this way, the cost of manufacture is reduced while improving ability and brake performance with the low adjusting expense.</p> |
