Abstract:
A coupling arrangement comprising:a first coupling part (3) connected to a working machine (1), the first coupling part having first fluid coupling means (12, 14; 12a, 14a) and abutment means (6, 6a);a second coupling part (4) connected to a working implement and having second fluid coupling means (18, 19; 18a, 19a);the first coupling part (3) has drive means (10, 14, 14a) for maneuvering the first fluid coupling means (12, 14; 12a, 14a) into connection with said second fluid coupling means (18, 19; 18a, 19a)the second fluid coupling means (18, 19; 18a, 19a) are movable in the maneuvering direction;a connection means (7, 17; 7a, 17a) for connecting the first coupling means with the second coupling means;the drive means (10, 24, 24a) having a stroke length sufficient to move the first fluid coupling means (12, 14; 12a, 14a) into contact with the second fluid coupling means (18, 19; 18a, 19a) and the stroke length is sufficient to move said second fluid coupling means (18, 19; 18a, 19a) into abutment with the abutment means (6, 6a); andat least one spring means (20, 20a) which functions to act on said second fluid coupling means (18, 19; 18a, 19a) with a spring force that is opposed to said maneuvering movement.
