The clamping device is provided for tools and has a coupling piece that is provided with at least one actuating unit. The coupling piece acts to actuate a nut seated on a spindle journal that is receiving the tool. A torque coupling is provided for the nut. The coupling piece is fixedly connected with an output shaft that is in drive connection with a drive shaft by a transmission gear. As a result of the transmission gear, it is possible to rotate the drive shaft with minimal moment in order to apply the great clamping force required for axial clamping of the tool.

The present invention provides an active clutch mechanism and a hopping robot equipped with the same, the active clutch mechanism comprising: a sun gear; a planetary gear; and a winding gear. When the sun gear rotates in one direction, the planetary gear revolves around the sun gear in the one direction to come into contact with the winding gear, and then rotates the winding gear to wind a wire so as to store energy in an energy storage unit connected to the winding gear. When the sun gear rotates in a direction opposite to the one direction, the planetary gear revolves around the sun gear in the direction different from the one direction to become spaced from the winding gear, so as to discharge the energy stored in the energy storage unit.

A motor vehicle vacuum pump includes a pump rotor, a coupling element, and a clutch arrangement. The clutch arrangement locks or releases the coupling element to/from the pump rotor so that the coupling element rotates together with or is released from the pump rotor. The clutch arrangement comprises a bolt holder connected to the pump rotor or to the coupling element to rotate therewith, an axially displaceable guide body, and a catch body connected to the coupling element or to the pump rotor to rotate therewith. The bolt holder comprises a bolt guide and a bolt body displaceable therein. The guide body is assigned to the bolt holder and comprises a guiding surface inclined with respect to an axial plane. The bolt body is forced radially into a locking position via the guiding surface. The catch body has a catch depression wherewith the bolt body engages in the locking position.

Disclosed are latching mechanisms for engine disconnect devices, methods for making and for using such latching mechanisms, and motor vehicles with a disconnect device for coupling/decoupling an engine with a torque converter (TC). A disconnect clutch for selectively connecting an engine with a TC includes a pocket plate that movably mounts to the TC. The pocket plate includes pockets movably seating therein struts that engage notches in a notch plate to lock the pocket plate to the notch plate. A selector plate moves between deactivated and activated positions such that the struts shift into and out of engagement with the notch plate notches, respectively. An activation device is selectively actuable to move the selector plate between activated and deactivated positions. A latching mechanism automatically transitions to a latched state responsive to the selector plate being activated. When latched, this latching mechanism retains the selector plate in the activated position.

A clutch for an automatic transmission includes a tubular housing surrounding a clutch pack and having an end for engaging with a pressure plate. An annular separator spring on the end provides a biasing force against the pressure plate. A plurality of depressible pins are disposed in the housing and are located radially outward from the annular spring for inhibiting radial movement of the separator spring.
