Kinematic scheme of a probe-cone docking mechanism for future advanced spacecraft

Docking mechanism of the probe-cone type have been using for about 40 years to dock Russian spacecraft and modules. The paper proposes a new kinematical scheme for such a mechanism in order to reduce contact dynamic loads and to provide a capability to dock with passive parts which have receiving cones of various configurations. The new mechanism has the following distinctive features that set it apart from the existing design. A two-stage friction clutch is used instead spring and electromagnetic brakes in axial damper. The universal joint of moving body was relocated to the base of docking mechanism and orientation of springs and electromagnetic brakes of lateral damper is changed to accommodate this new position. The aligning levers rollers of existing mechanism are replaced with a limit device that can move along longitudinal axes of moving body. The new docking mechanism is designed, primarily, for new advanced manned spacecraft, as well as other spacecraft and modules.
