Abstract: Disclosed is a cone brake no-back for use with an actuation system. The actuation system may be an aircraft actuation system, for example. The no-back may include cone brakes capable of preventing undesired displacement of an aircraft surface (such as a flap, a leading edge, or a trailing edge of a wing) in the event that an actuator input becomes disconnected or is otherwise insufficient to oppose the load created by the aircraft surface.

Abstract: A new asymmetrically damped tensioner is provided utilizing a bearing-ramp clutch. During normal operation, the bearing-ramp clutch enables the tensioner arm to pivot in a first direction to take up belt slack with negligible frictional damping applied to the motion of the tensioner arm. When the tensioner arm pivots in a second direction, away from the belt, however, in a condition commonly known as wind-up, the bearing-ramp clutch locks against a fixed internal surface and creates a frictional damping force that is applied to the tensioner arm. This frictional linkage provides asymmetric frictional damping to the tensioner to limit movement in the second direction to mitigate wind-up.

Abstract: A drive mechanism for a medication delivery device (1) is proposed, the drive mechanism comprising a housing (13, 17, 40) having a proximal end and a distal end, a rotation member (21) which is adapted to be rotated in a first direction with respect to the housing during setting of a dose of a medication and to be rotated in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction, a piston rod (12) which is adapted to be displaced in a distal direction with respect to the housing for delivering the dose, a drive member (20) which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member (26) which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose, wherein the rotational movement of the drive member in the second direction is converted into movement of the piston rod in the distal direction wit

Abstract: A fall safety device is provided having a load-bearing rotor 2, which supports at least one locking member 6, which can be moved by centrifugal force and which is moved into engagement with at least one stop 7b of a stator 4 if a certain rotor speed is exceeded and blocks the further rotation of the rotor 2. The locking member 6 and/or the stop 7b is in active connection with a braking body 8, which undergoes a plastic deformation when engaging the fall safety device and damps the stopping process.

Abstract: A clutch assembly 10 is provided for a motor having a shaft 36, a worm 40 associated with the shaft and an output gear 42 engaged by the worm. The clutch assembly includes a clutch body 12 having a plurality of pockets 22 in a surface thereof. Each pocket has a cam surface 24 defined by a depth of the pocket that gradually increases from a deep end to a shallow end. A ball bearing 18 is disposed in each of the pockets 22. Spring structure 16 maintains the ball bearings in the pockets. A pressure plate 14 is operatively associated with the clutch body and is constructed and arranged to be coupled with the shaft 36 of the motor. Under certain conditions, the ball bearings wedge between the pressure plate and surfaces defining the associated pocket, thereby preventing rotation of the shaft when coupled with the pressure.

Abstract: A brake assembly permits axial rotation of a shaft in a first direction and retarding axial rotation of the shaft in an opposite, reverse direction. The brake assembly includes a rotary member for mounting to and rotation with the shaft; a fluid actuated brake mechanism for retarding the rotation of the rotary member and consequently the shaft upon pressure build up in the brake mechanism; a bi-direction pump for conveying fluid from a reservoir, the pump being driven by rotation of the shaft; and a control manifold for directing circulating the fluid from the pump through the brake mechanism and back to the reservoir without pressure build up, the circulation of the fluid preventing the accumulation of gas in the brake mechanism, when the shaft turns in the first direction and or directing fluid to the brake mechanism for activating the brake mechanism by fluid pressure build up to retard rotation of the shaft when the shaft turns in the reverse direction.

Abstract: In a wheel drive with a radial-piston motor (5) and a planet gear (4) a wheel hub (3) being placed on a wheel hub support (1) by means of wheel bearings (10). The wheel hub support (1) can be joined to a transmission connector (4) in a single piece and is fastened to a vehicle chassis support. A dog tooth brake (7) is located on the side of the wheel drive facing the vehicle and serves as parking brake. In a cover (2) for a hydraulic connection of the radial-piston motor (5) are integrated valves for control of the radial-piston motor (5) and of the brake (7). Short lines and delay times occur as result. The cover (2) contains inter alia a brake valve (58) for a hydraulic brake function and a displacement change-over valve (64) enabling certain cylinders (70) of the radial-piston motor (5) to be switched on or off.
