Abstract
A fifth-wheel coupling (1) having a coupling plate (2) with an entry opening (4) for a king pin (5) includes an at least single-part locking device (100) for fastening the king pin (5) and a fixing element which engages on the locking device, which fixing element can be moved from a locking position into an open position and vice versa. A securing device (15) with a blocking element (40, 400) is provided, which blocking element (40, 400) can be moved from a rest position into a blocking position and vice versa, wherein the blocking element (40, 400) projects into the entry opening (4) at least in the blocking position.
Claims40
Fifth-wheel coupling (1) comprising:
- a fifth-wheel coupling plate (2), on which an entry opening (4) for a kingpin (5) is disposed;
- a locking device (100) for fixing the kingpin (5) in place;
- a fixation element that is laterally movable from a locking position into an open position and vice versa, wherein the fixation element projects into the entry opening in the locking position and engages on the locking device (100);
- and
- a security device (15) having a blocking element (40, 400) that is laterally movable from a rest position into a blocking position, and vice versa;
- wherein the blocking element (40, 400) projects into the entry opening (4) at least in the blocking position, and the blocking element (40, 400) is fixed in place in the blocking position when the fixation element is in the open position in unauthorized manner.
Fifth-wheel coupling having a fifth-wheel coupling plate (2), on which an entry opening (4) for a kingpin (5) is disposed, having a locking device (100) for fixing the kingpin (5) in place, and having a fixation element that engages on the locking device (100), which fixation element can be moved from a locking position into an open position and vice versa, characterized in that
- a security device (15) having a blocking element (40, 400) is provided, which blocking element can be moved from a rest position into a blocking position, and vice versa,
- the blocking element (40, 400) projects into the entry opening (4) at least in the blocking position,
- the blocking element (40, 400) can be fixed in place in the rest position,
- the blocking element (40, 400) is fixed in place in the blocking position when the fixation element is in the open position in unauthorized manner,
- means for fixation and release of the blocking element (40, 400) are provided, which comprise a first activation device (50) having disabling means and having at least one actuator (54), and
- a second activation device (60) having disabling means and an actuator (64) for fixing the fixation element in place in its locking position are provided.
