The Force Control Oil Shear products come in several varieties of clutch and brake combinations including clutch only, brake only, combination clutch and brake, and a dual clutch brake unit.
This unique design assures there is never any overlap of clutch and brake, provides internal circulation of the transmission fluid, and minimizes inertia.
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.
A brake consists of steel drive plates 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 housing.
Pressure can be applied by air/hydraulic pressure or springs, or a combination of both. See Logic types.
A clutch/brake is a combination of both a clutch stack and a brake stack operating about a common output shaft. As a centrally located piston 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 braking torque is transmitted to the output shaft.
The single-centrally located piston prevents clutch and brake overlap.
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 primary and secondary input shafts may be driven in a variety of ways to select different speeds or directions as desired.
