The invention discloses a friction plate type self-adapting automatic separation driving
assembly of an inner rotor motor of an
electric motor cycle. The friction plate type self-adapting automatic separation driving
assembly comprises a driving motor, a tank body, and a main shaft which is matched with the tank body in a rotating manner and outputs power, and further comprises a gear base, a
clutch assembly, a first-stage gear, a transmission unit, a one-way gear and a one-way limiting screw
cam. According to the friction plate type self-adapting automatic separation driving assembly disclosed by the invention, a novel plane type
clutch assembly is used for transmitting torque, so that the friction plate type self-adapting automatic separation driving assembly has the advantages of being simple in structure, fast and convenient to assemble, easy to process, good in
joint surface, fast in separation, free from
impact, stable in torque force value, and the friction area can be infinitely increased. Through adjusting the number of external tooth friction pieces and the number of inner tooth liners and / or adjusting torque, nuts are adjusted to meet different requirements for the torque; when the torque is greater than a calibration value of the
clutch assembly, the one-way limiting screw
cam drives a thrust limiting screw
cam, so that the external tooth friction pieces and the inner tooth liners are mutually loosened, the situation that the pressure in an axial direction is infinitely increased is effectively limited, the situation that the
axial pressure of the main shaft is lower than 5000N is guaranteed, and the damage of a bearing on the main shaft is avoided.
