A clutch assembly for a lock includes a driver (1), having a driver shaft (9); a coupler (3); and a follower (2). The driver (1), the coupler (3) and the driver shaft (9) are configured to rotate concentrically together. The coupler (3) is configured to move along the central axis of the driver shaft (9) to couple to or decouple from the follower (2). The driver (1) and the follower (2) are configured to rotate concentrically together when the coupler (3) is engaged to the follower (2), and wherein the driver (1) and the follower (2) are configured to rotate independently when the coupler (3) is disengaged from the follower (2).

A drive wheel clutch system for manually disengaging one or more drive wheels from their driveshafts. The drive wheel clutch system generally includes a driveshaft, a flange at one end of the driveshaft, and a flange-engaging member. The flange-engaging member and the flange may be generally disc shaped. The flange-engaging member is spring loaded and includes locking members that can extend through apertures in the flange to engage with locking apertures in the hub of a drive wheel. An operator can pull against spring bias and rotate a handle connected to the flange-engaging member to disengage the locking members from the flange and the hub, allowing the wheel to turn freely while the driveshaft remains stationary.

An actuator producing an active movement between fastening elements of the actuator and damping a counter movement contains a main body having a first fastening element, an actuating body movable relative to the main body along an axial direction and having a second fastening element, and an electric motor for actively driving the actuating body exclusively in a driving direction along the axial direction and for passively damping a counter movement of the actuating body counter to the driving direction being brought about by external action on the fastening elements. An object assembly contains an object and the actuator in which the spring element is structurally separate from the rest of the actuator, and an interaction between the spring element and the rest of the actuator is achieved in an object to be operated by the actuator, at least in a correctly mounted state of the actuator.

A double clutch assembly includes a first clutch assembly and a second clutch assembly. The first clutch assembly includes a cylinder (21), a driver assembly, comprising a control member (11), a driver (1), and a driver shaft (9), wherein the control member (11), the driver (1), the driver shaft (9) and are configured to rotate concentrically together and a follower (2). The cylinder (21) is connected to the driver shaft (9). The rotation of the cylinder (21) causes the driver shaft (9) to engage with or disengage from the follower (2). The second clutch assembly includes an actuating assembly and a coupler (3). The coupler (3) relates to and is configured to rotate concentrically with the driver assembly. The actuating assembly is operably connected to the coupler (3) and is configured to move the coupler (3) causing the coupler (3) to disengage from or engage with the follower (2).

A mechanical clutch allows for transfer of torque downhole that may avoid the need for a hydraulic electrical coil-driven piston. In one or more examples, an anti-rotation guide for a downhole clutch includes a guide track and a follower moveable along the guide track for guiding relative movement between an upper armature and a lower armature. The guide track includes an axially-extending portion terminating in a circumferential loop. The axially extending portion guides the upper armature into axial engagement with the lower armature in response to rotation of the input shaft. The circumferential loop thereafter allows rotation of the upper and lower armatures together in response to further rotation of the input shaft.
