PCT No. PCT/EP88/00973 Sec. 371 Date May 7, 1990 Sec. 102(e) Date May 7, 1990 PCT Filed Oct. 28, 1988 PCT Pub. No. WO89/04431 PCT Pub. Date May 18, 1989.In a stopping device for a shaft, which acts in all three dimensions and is unaffected by large accelerations, a gear on the shaft of an engine is stopped by a locking pawl which engages the gear when the electromagnet is not excited. A magnetic field generated by the passage of current through a coil produces a torque which turns the rotating armature against the force of a spring in such a way that the locking pawl is moved radially outward around the gear and over a guide pin on the rotating armature which can be moved in a guide slot of the locking pawl, and thereby releases the gear and hence the shaft. |
