A brake device of a transmission according to the present invention includes: a rotary-side holding member including an inner peripheral surface having a cylindrical surface shape about an axis extending in a forward/rearward direction and configured to hold a rotary-side friction plate on the inner peripheral surface; a fixed-side holding member including an outer peripheral surface having a cylindrical surface shape about the axis extending in the forward/rearward direction and configured to hold a fixed-side friction plate on the outer peripheral surface; and a lubricating oil supply portion supplying lubricating oil to the fixed-side friction plate and the rotary-side friction plate. The fixed-side holding member is provided in a transmission casing so as not to rotate. The rotary-side holding member is provided in the transmission casing at a radially outer side of the fixed-side holding member and is rotatable about a central axis of the inner peripheral surface.

A hydraulic power take-off is provided for use with industrial drives that deliver power to industrial equipment. The hydraulic power take-off has a brake disconnect system that can manually release a brake assembly to allow low-effort rotating of the industrial equipment components to facilitate servicing.

A hydraulic power take-off is provided for use with industrial drives. The hydraulic power take-off has a multiple-force brake system that facilitates actively slowing large inertial loads associated with a heavy rotating mass of an industrial machine. The multiple-force brake system applies different braking forces at different times to control deceleration of the heavy rotating mass in the industrial machine to reduce its stopping time. The multiple-force brake system may include a clutch assembly and a brake assembly. A control system may control the clutch and brake assemblies to provide the multiple-force brake system a relatively higher energy brake engagement state and a relatively lower energy brake engagement. This may include alternating between the higher and lower energy brake engagement states to pulse between high and low pressure braking to facilitate cooling of the system while slowing the large inertial loads.

A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

A module for a system for driving and synchronizing a countershaft of a transmission gearbox. The module includes a coupling device having an input element intended to be rotationally coupled to a reversible electric machine and an output element intended to be rotationally coupled to the countershaft. The coupling device has a coupled state in which the clutch device is able to transmit torque between the input element and the output element and an uncoupled state in which the input element and the output element are uncoupled. Also included is a lock-up device which has a lock-up state in which said lock-up device blocks the rotation of the input element of the clutch device, and a released state in which said lock-up device allows the input element to rotate.

A working vehicle includes a PTO shaft to transmit power of a propulsion shaft, a PTO clutch including a first rotor to be rotated by the power of the propulsion shaft, a second rotor to transmit the power to the PTO shaft, a press to be moved by a pressure of operation fluid between an engaging side on which the first rotor is engaged with the second rotor and a disengaging side, and a PTO brake to brake the PTO shaft when the press is positioned on the disengaging side, a control valve to control the pressure of the operation fluid to be applied to the PTO clutch, a rate setter to set a reducing rate at which the pressure of the operation fluid is reduced, and a controller to control the control valve based on the reducing rate.

The invention relates to a method for operating a combined clutch and brake device (5) of a punch press (1) equipped with dry friction linings (7, 8). Thereby, the friction linings (7, 8) are arranged in a chamber (R) which is sealed off from the environment of the punch press (1), and which is filled with a dry and oil-free gaseous medium, in particular with dry oil-free air. This effectively prevents moisture and oil mist from entering the region of the friction linings from the environment of the press, and a constant friction coefficient can be achieved over the mechanical service life of the friction linings.
