Problems solved by technology

When the friction plate electromagnetic clutch is engaged, the electromagnetic force generated by the electromagnetic coil energization compresses the active friction plate and the driven friction plate to transmit torque. When transmitting large torque, the radial size of the input plate and the driven plate must be increased, Large electromagnetic coil energizing current increases the number of active friction plates and driven friction plates, so there are disadvantages such as large volume, low speed, and high power consumption; the tooth-jaw electromagnetic clutch transmits large torque, and requires low speed difference when engaging, and there are The disadvantage of high power consumption; the magnetic powder clutch has a fast response and can achieve fine-tuning of the accuracy according to the current, but there are disadvantages such as high power consumption, temperature rise when the slip is large, and high cost; when the slip electromagnetic clutch is working, There must be a certain speed difference between the driving and driven parts to transmit torque, and the eddy current in the rotor will generate heat, which is proportional to the speed difference

Abstract

The invention discloses an electromagnetic clutch with a wire-driven friction and meshing transmission joint device. When a solenoid coil is not electrified, under the action of a return spring, an internal splined hub with lateral teeth and a spline coupling with lateral teeth are not in meshing transmission, and the clutch is in a disengaged state; and when the solenoid coil is electrified, under the action of an electromagnetic force, a spline housing overcomes the elastic force of the return spring and moves toward an electromagnet, and the internal splined hub with lateral teeth and the spline coupling with lateral teeth are in meshing transmission, so that synchronous transmission of the internal splined hub with lateral teeth and the spline housing is realized, and the clutch is engaged.

Description

Technical field [0001] The invention relates to a clutch, more specifically an electromagnetic clutch of a wire-controlled friction and meshing transmission engagement device. Background technique [0002] The existing electromagnetic clutches can be divided into: friction plate type electromagnetic clutch, jaw type electromagnetic clutch, magnetic powder clutch, slip type electromagnetic clutch and so on. When the friction plate electromagnetic clutch is engaged, the electromagnetic force generated by the energization of the electromagnetic coil compresses the friction force generated by the active friction plate and the driven friction plate to transmit torque. When transmitting large torque, the radial size of the input disk and the driven disk must be increased. The large electromagnetic coil energizes the current and increases the number of active and driven friction plates, so it has the disadvantages of large volume, low speed and high power consumption; the jaw type elect...
