Abstract
Each coupling head of a vehicle coupling comprises a spring accumulator 50 consisting of compression springs 27, 30 which are energized by a pressure bar 20 when a tension bolt 3 of the head is moved inward. The coupling of the tension bolt 3 in a tension bolt receptacle 4 occurs by engagement levers 12, which are locked by a displaceable frame 16 in the coupled state. The unlocking is remotely operable by actuation of a solenoid 45 which actuates a latch 32 through an unlocking bar 41. Because of this unlocking, the frame 16 is displaced by the force of the spring accumulator, so that the locking of the engagement levers 12 is released and the coupling can be decoupled.
Claims16
Automatic coupling for a rail vehicle having two similar coupling heads, each said coupling head comprising:
- (a) a tension bolt;
- (b) a tension bolt receptacle;
- (c) a locking mechanism in the receptacle;
- (d) a unlocking device connected to the locking mechanism;
- (e) means connected to the locking mechanism and operable during the coupling process for storing energy;
- (f) means operable upon actuation of said unlocking device to release the energy stored in said energy storing means for actuating said locking mechanism so that it will allow decoupling.
Automatic coupling for a rail borne vehicle having two similar coupling heads with each coupling head comprising both a tension bolt and a tension bolt receptacle provided with a locking mechanism connected with an unlocking device, characterized in that the coupling head comprises a spring accumulator operable during the coupling process for storing energy, and means operable during the decoupling process by the energy stored in the spring accumulator for bringing the locking mechanism into a position whereby a head can be decoupled and is made ready for the next coupling.
Coupling according to 14, characterized in that the engagement lever has a lever ratio of approximately h:H =1:3 between the line of action of the tractive force at the contact face at the clamping surface of the tension bolt and the contact face in blocking position at the contact contour of the frame.
