摘要： An assembly for driving a friction clutch, having a hydraulically driveable stepped piston, with: a pump driving the stepped piston, which has a working piston moveably arranged in a working chamber that divides it into first and auxiliary working chambers. The working piston is mechanically connected to an auxiliary working piston and hydraulically driveable via a second working chamber. A control valve is arranged between the stepped piston and pump. A first line path leads from the pump to the second working chamber, and a second line path leads from the pump to the first working chamber. The stepped piston has a working tappet which acts on the friction clutch. The first and second line paths are connected via a first line section of the supply line and a multi-port control valve, which has two valve positions, and the first line section is at least partially blocked in one valve position.

摘要： A hydraulic control system includes a hydraulic pump driven by an electric motor, a solenoid valve having an output that controls the positions of a pressure regulator valve and a third, stator shift valve. The solenoid valve is a normally high, variable force solenoid valve which provides a control signal to the second and third valves. The second, pressure regulator valve is a multiple port valve which controls hydraulic fluid flow both to a transmission oil cooler (ATOC) and to an exhaust port, thereby maintaining a desired system pressure. The third, stator shift valve is also a multiple port valve and it controls fluid flow to the stator of the electric pump motor to provide cooling and to a dog clutch of the transmission to disengage it.

摘要： A hydraulic system is provided, comprising a hydraulically actuated clutch, a hydraulically actuated shifting piston, and a pressure source for actuating the clutch as well as the shifting piston. The movement of the shifting piston also controls a valve function which serves to open a connection from the pressure source to the clutch only when the shifting piston has reached one of its end positions.

摘要： A check valve assembly for a clutch, including: an annular-shaped ring element including a first portion with: a first channel wholly enclosed by the first portion; a first through-bore between a radially inner surface of the first portion and the first channel; and a second through-bore between a radially outer surface of the first portion and the first channel. The assembly includes a first pressure regulating assembly at least partially disposed within the first channel and including: a spool axially displaceable within the first channel and including a space enclosed by the spool; a first ball disposed within the space and the first channel; and a first spring engaged with the spool. The spool is arranged to axially displace in response to hydraulic pressure at the first through-bore and axial force applied by the first spring to displace the first ball to block or unblock flow between the first and second through-bores.

摘要： Apparatus, system and method for providing supplementary power. A vessel is configured to receive and contain hydraulic fluid, where the vessel includes a piston configured within the vessel to be vertically displaced by the hydraulic fluid and provide pressure from the weight of the piston to a fluid supply line. A solenoid valve is operatively coupled to the fluid supply line; and connected to a flywheel power supply that includes a flywheel and a hydraulic drive adapter, wherein the hydraulic drive adapter is operatively coupled to the solenoid valve via the fluid supply line. A signal is received indicating a power outage, where the solenoid valve is further configured to open in response to the signal and provide the hydraulic fluid pressurized by the piston to the hydraulic drive adapter and causes the flywheel to operate and provide the supplementary power.
