摘要： A drive system has a pair of planetary gear sets located between an input shaft and an output shaft with an intermediate shaft located between the pair of planetary gear sets. A series of oil shear brakes and clutches allow the drive system to operate in neutral, high speed forward, high speed reverse, low speed forward and low speed reverse. These operating modes are selectable without having to stop and reverse the input shaft which is allowed to rotate constantly in the same direction during all of the above operational modes.

摘要： A control system for a press having a clutch and a brake includes a clutch control valve and a brake control valve. The clutch control valve operates the clutch by supplying pressurized air to the clutch. The brake control valve operates the brake by supplying pressurized hydraulic fluid to the brake. The brake control valve is activated by pressurized fluid from the clutch control valve in order to insure simultaneous release of the brake with engagement of the clutch as well as simultaneous application of the brake with disengagement of the clutch.
摘要翻译： 用于具有离合器和制动器的压力机的控制系统包括离合器控制阀和制动控制阀。 离合器控制阀通过向离合器供应加压空气来操作离合器。 制动控制阀通过向制动器供应加压液压流体来操作制动器。 制动控制阀由来自离合器控制阀的加压流体启动，以便通过离合器的接合来确保制动器的同时释放，以及在离合器脱离时同时施加制动器。
