An electric axle is configured to selectively enable an electric motor to power a pair of drive shafts of a vehicle. The electric axle includes a planetary gearset configured to drivably couple an electric motor with first and second drive shafts coaxially arranged. The planetary gearset including a ring gear. A housing at least partially surrounds the planetary gearset and is configured to be grounded to the vehicle. A clutch is configured to selectively ground the ring gear with the housing to enable an electric motor to power the first and second drive shafts. The electric axle may include a second planetary gearset, namely a differential planetary gearset. The differential planetary gearset may include a carrier that is shared or common amongst the planetary gearset and the differential planetary gearset.

A power switching device for switching power between translational motion and rotational motion includes an active gear, a transmission mechanism, a translation mechanism, a functional gear, and a reset mechanism. The active gear can rotate in a first direction or a second direction opposite the first direction. The translation mechanism includes a runner and a pushing member. The active gear can switch between a first position and a second position. In the first position, the active gear meshes with the runner and rotates in the first direction or the second direction to drive the runner to rotate. In the second position, the active gear meshes with the transmission gear and rotates in the second direction to drive the functional gear to rotate.

A transmission clutch module includes an inner race, an outer race, and a plurality of race engaging pawls adapted to selectively secure the races together in either a locked position or an unlocked position. The clutch module includes 5 an actuator cam configured to be moved between two angularly spaced positions to control the pawls. The inner race is comprised of two axially spaced inner race plates axially secured together by rivets for retaining, and accommodating angular limited movements of the pawls. The pawls are circumferentially disposed about the inner race plates, and are radially outwardly biased by springs 10 to engage the outer race, unless blocked by the actuator cam. The pawls are weighted at one end, so that at a threshold speed of the inner race, they can overcome spring resistance to disengage from both the actuator cam and the outer race.

A device for the shaft-hub coupling, in particular for the automotive sector. The peculiarity of this device is that it comprises a box-like body (4) arranged to be inserted inside a shaft (2), to be coupled with a hub (3). The body (4) further has removable means (5, 5′, 5″), operable by means of a lock (6), for engagement with the hub (3).

A surgical instrument comprising a shiftable transmission is disclosed. The transmission comprises a mechanism for assuring that the transmission is in one of a plurality of predefined configurations.

A kit of parts includes a ceramic element comprising a cylindrical bore having at least one recess, and a rod comprising an outer tube comprising a jutting portion adjacent to an insert portion. An outer tube wall mates with the cylindrical ceramic bore. An outer tube bore comprises a cylindrical portion. An outer tube projecting member is insertable into a recess in the cylindrical bore. An inner mandrel insertable into the outer bore stabilizes a projecting member in a recess to couple the rod to the ceramic element.
