  • Double clutch per side two lever arrangements by means of which a Gear and a rack, the sleeve are moved against the spring force can.
  • the disadvantage of such a double clutch is that it is expensive built and expensive to manufacture is that it takes up a lot of space and that nevertheless a large force must be applied for uncoupling.
  • a quick-release device for short couplings known by rail vehicles.
  • This includes a coupling head, on which is arranged around a bolt rotatable angle lever on the shorter lever arm of the angle lever is hinged a closure piece, which is attached to a stop the counter-coupling attacks and the two clutches clamped together.
  • the Closure piece in turn is loaded by means of a tension spring so that this in an open position pivots when no more forces on the closure piece act.
  • a clamping screw is provided, which is arranged on a bridge, which in turn can be folded down with a bolt is hinged to the coupling.
  • the locking force reduced by the lever assembly so far that the clutch assembly can be unlocked manually even at high tensile load. Because of that Latch of a coupling device of the other coupling device from the rest to the locked position and unsecured release lever can also be moved back, the two coupling devices a Coupling arrangement fully automatically coupled and after releasing the release lever be decoupled again.
