Clutch

Clutch

A clutch consists of multiple rotating steel drive plates keyed or pinned to the input shaft and alternating friction discs splined to the hub of the output shaft.Pressure acting on the non- rotating piston exerts clamping pressure on the clutch stack through a thrust bearing and a rotating thrust plate.The clutch is engaged and torque is transmitted from the input shaft to the output shaft.

Brake

Brake
A brake consists of multiple rotating steel driveplates keyed or pinned to the housing and alternating friction discs splined to the hub of the output shaft.Pressure acting on the non- rotating piston exerts clamping pressure on the brake stack.The brake is engaged and torque is transmitted from the output shaft to the hous- ing. Clutch/Brake

Clutch/Brake

A clutch/brake is a combination of both a clutch stack and a brake stack operating about a com- mon output shaft.As a centrally located piston assembly is shifted to exert clamping pressure on the clutch stack, torque is transmitted from the input shaft to the output shaft.When shifted away from the clutch stack to the brake stack, the clutch is automatically released and brak- ing torque is transmitted to the output shaft. The single-centrally located piston prevents clutch and brake overlap. Dual Clutch/Single Brake

Dual Clutch/Single Brake

A dual clutch/brake consists of two clutches and a brake operating about a common output shaft.Two separate pistons are used to exert clamping pressure on either the primary clutch, secondary clutch or the brake.The pri- mary and secondary input shafts may be driv- en in a variety of ways to select different speeds or directions as desired. b
