Abstract
The invention discloses a magnetic powder clutch capable of achieving locking-up mechanically. A magnet yoke electromagnetic coil is energized only in the joint process of a driving rotor and a driven rotor. After the magnet yoke electromagnetic coil is de-energized, electric finger pin valves control finger pins to enter arc-shaped ring grooves. The electric finger pins are connected with the driving rotor and the driven rotor in a locking-up mode to make the driving rotor and the driven rotor to lock up the transmission state synchronously. According to the magnetic powder clutch capable of achieving locking-up mechanically, the temperature rise problem caused by long-term energization of the magnet yoke electromagnetic coil of the magnetic powder clutch is effectively solved. The magnetic powder clutch capable of achieving locking-up mechanically is particularly suitable for the place where the magnetic powder clutch needs to be jointed for a long time and work at large torque and high load. The magnetic powder clutch has the advantage of high transmission efficiency.
