A platform for research: civil engineering, architecture and urbanism
An electromagnetic actuator has coils (60, 62 fig 4) and a linearly moveable armature 14 and includes a fail-safe mechanism (spring 30) which is deployed by release assembly 40 in the event of electrical or other system failure. The release assembly may comprise a solenoid 42 and rods 44 and 50 attached to tubular body 32 by pivot 52. Rod 50 (trigger member) acts to keep plate 38 in place so that coil spring 30 remains in a retracted position during normal operation of the actuation device. When the fail-safe mechanism is triggered, the rods extend and release the coil spring which pushes the circular plate 38 towards the actuation device 4. By keeping the fail-safe spring in a retracted position during operation of the device, energy consumption is reduced. The linear electromagnetic actuator may be used to operate a lock assembly for selectively locking the rotational position of a shaft (fig 4). The lock assembly may be a park lock for a vehicle but it may also be any industrial machinery that uses rotating components.
