Abstract
The invention discloses an electric stud type dynamic joint bidirectional clutch with a buffer disc. When electric stud valves are not powered on, under the action of reset springs, the tail ends of the electric studs do not make contact with the end face of an output disc, and the output disc is in a separation state; when the electric stud valves are powered on, under the action of electromagnetic force, the electric studs overcome elastic force to move towards an input disc and slide into an arc annular groove in a rotating state to push the output disc to conduct synchronous rotation; and meanwhile the output disc pushes the buffer disc to rotate through rubber spring elements, so that synchronous transmission of the input disc and the buffer disc is achieved, and joint of the clutch is achieved. The structures that the two edges are deep and the middle is shallow are adopted for the arc annular grooves, so that the input disc can conduct synchronous rotation with the output disc in both the forward rotating state and the reverse rotating state, and bidirectional joint of the clutch is achieved.
