A shifting device for a motor vehicle is described, comprising a first coupling component which is adapted to be selectively rotationally coupled to a second coupling component with a form-fit. In an open state, the first coupling component is rotationally decoupled from the second coupling component. In a frictional fit state, the coupling components are rotationally coupled with a frictional fit via a first frictional fit ring and a second frictional fit ring. In a form-fit state, an actuating ring is rotationally coupled to the first coupling component and the second coupling component with a form-fit such that the latter are connected with a form-fit. A motor vehicle transmission, in particular a fully automatic stepped transmission having such a shifting device is additionally presented.

A hydraulic pump with an integrated clutch includes an outer cone coupled to a drive gear or a driven gear and having a frictional inner surface, and an inner cone arranged inside the outer cone, coupled to the drive gear or the driven gear and having a frictional outer surface, wherein the inner and outer cones are rotationally and axially movable with respect to each other. A spring is coupled to the inner cone or the outer cone and acts to axially displace the inner cone with respect to the outer cone in a first direction. An actuator including a rod and a piston is coupled to the inner cone or the outer cone and acts to overcome the force of the spring to axially displace the inner cone with respect to the outer cone in a second direction being axially opposite to the first direction.

An exemplary cone brake device includes a brake drum and a thermal sprayed coating deposited and bonded to the outer surface. The thermal sprayed coating is configured to engage a friction lining when one of the brake drum and the friction element is moved toward the other of the brake drum and the friction element, so as to decrease the speed of an aerospace propeller.

A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.
