ABSTRACT:
A dual clutch for an inching arrangement in a load sharing drive which has two or more driving motors connected to a load through a dual clutch. The clutch has two (or more) clutch units mounted side by side on a driving shaft with an inflatable, flexible tube in each unit for pressing respective friction shoes outwardly, when inflated, against a surrounding cylindrical drum. The drum is mounted to a driven shaft. The driving shaft has a central bore connected through a solenoid operated valve to a supply of pressurized air when the valve is in an operating position and to an exhaust when the valve is in a dump position. Each of the tubes is connected to the central bore through a respective air line. A needle valve in one of the air lines provides a restriction to the flow of air into and out of the respective tube. The restriction is sufficient to substantially isolate the associated tube when the solenoid operated valve is operated to its dump position for a short time interval and then returned to its normal position. Thus, during a short pulse of reduced air pressure caused by the operation of the solenoid operated valve, the air flows largely out of only one tube thereby reducing the volume of air dumped to cause momentary slipping and improving the dynamic response of the clutch.
