Hydraulic torque transmission overload coupling - has number of actuating cylinder and piston arrangements distributed over coupling disc circumference

摘要

The torque overload coupling has a coupling disc and drum. The arrangement has a number of actuating cylinder and piston arrangements distributed over the coupling disc circumference. The coupling components ensure rolling with rolling friction on overloading. The bearing pins (6) with an actuating cylinder and piston arrangement (4) are connected by a fastener bolt (11). This fastener has circumferential play between the bearing pin (6) and the actuating cylinder and piston arrangement (4). The actuating rollers (7) are guided by the holding chambers (3). In case of overloading, rolling takes place between the actuating rollers (7) and the rolling elements (8) in the housing.
