Abstract
A dual-rotor force transmitting assembly includes a powerhead assembly having a spring housing, a plurality of first spring sets that generate a braking force for a first rotor and a plurality of second spring sets that generate a braking force for a second rotor. Using separate spring sets for each rotor ensures application of uniform and equal pressure on both rotors even if there is uneven friction surface wear.
Claims20
An assembly for transmitting force to a shaft, comprising:
- a mounting flange having a central opening to receive the shaft;
- first and second rotors mounted on the shaft and rotatable with the shaft, the first and second rotors each having at least one planar surface;
- first front and rear reaction plates disposed on opposite sides of the first rotor;
- second front and rear reaction plates disposed on opposite sides of the second rotor, wherein the first and second front and rear reaction plates each have at least one friction surface that is engageable with said at least one planar surface on the first and second rotors;
- a piston;
- a cylinder coupled to the piston to form a fluid pressure chamber, wherein the piston moves in a first direction when pressurized fluid enters the fluid pressure chamber and the piston moves in a second direction when pressurized fluid exits the fluid pressure chamber;
- and
- a powerhead assembly operatively coupled to the piston, the powerhead assembly having
- a spring housing,
- a plurality of first spring sets supported in the spring housing and operatively coupled to the first front and rear reaction plates to bias the first front and rear reaction plates into engagement with the first rotor, and
- a plurality of second spring sets supported in the spring housing and operatively coupled to the second front and rear reaction plates to bias the second front and rear reaction plates into engagement with the second rotor,
- wherein the first spring sets and the second spring sets move independently from each other to separately bias the first front and rear reaction plates into engagement with the first rotor and the second front and rear reaction plates into engagement with the second rotor.
