  • Patent number: 6378679
    Abstract: The invention concerns a clutch (10), comprising a clutch disk (22) connected with a first shaft (A) and a brake device (17) connected with a second shaft (B). By means of the brake cylinder (19) of the brake device (17), the brake pad (18) can be coupled into engagement with the clutch disk (22), in which case a movement of rotation between the shafts (A and B) is prevented. In the solution of equipment, between the shaft (A) and the shaft (B), there is a support bearing (21), which supports the movement of rotation between the shafts (A and B) when the clutch is supposed to slip. According to the invention, in the pressure line (59), there is a holding pressure maintained by means of accumulators (100), which holding pressure determines the torque at which the clutch slips.
