CONNECTING-DISCONNECTING CLUTCH

The aim of the invention is in improvement of the design of connection-disconnection clutch through inclusion of additional structural elements in order to increase reliability and durability of the unit. The aim is achieved in such a way that the connecting-disconnecting clutch comprising of the body 7, the driving half-clutch 2, this is rigidly fixed on the drive shaft 1 of the clutch, the movable half-clutch 8 with ratchet mechanism, the drive section 12, includes rigidly fixed on the driven shaft 1 and connected to one piece by electron-beam welding synchronizer 4 and fixed half-clutch 3 with outer coupling teeth. Besides that, the movable half-clutch 8 has the inner and the outer coupling teeth, the driven part 12 û the inner coupling teeth, and is arranged as one piece with the body 7 of the clutch; at that the ratchet mechanism is made as two-row one, at that the ratchets 14 of the first row and the ratchet ring 15 of the second row are installed in the body of the driven part 12, and the ratchets 16 of the second row and the ratchet ring 17 of the first row are installed on the movable half-clutch 8; between the movable and the fixed half-clutches there is arranged a hydraulic cavity 21.
