The friction unit (7) consists of a pressure cone (8), spacer wedges (9), a base plate (10), movable plates (11) and guide plates (12). The friction unit (7) forms the friction pairs: "a spacer wedge (9) - a guide plate (12)", "a guide plate (12) - a movable plate (11)" and "a movable plate (11) - the housing (1)". The housing (1) and the friction unit (7) are configured to create an additional friction pair "a spacer wedge (9) - the housing (1)", which acts during the final period of applying the load to the cone (8).
