Fig. 91. Elements of a drive of the mechanism газораспределения: 1 — an intermediate shaft; 2 — a leading ring; 3 — a bolt, 10 Нм; 4 — a gauge drive; 5 — a bolt, 10 Нм; 6 — a bolt, 25 Нм; 7 — an elastic element of the tension device; 8 — the tension device двухрядной chains, 20 Нм; 9 — двухрядная a chain; 10 — a drive asterisk двухрядной chains; 11 — an asterisk of a drive of a single-row chain; 12 — the tension device of a chain with a boot; 13 — an asterisk of a drive of the chain, built in a cranked shaft; 14 — a single-row chain; 15 — a lath успокоителя; 16 — a special bolt, 25 Нм; 17 — a finger with буртом, 25 Нм; 18 — успокоитель; 19 — a bolt, 20 Нм; 20 — asterisks of cranked shaft





The drive of camshafts is carried out not directly, and through a gear of an intermediate shaft 1 (fig. 91).
Besides on intermediate to a shaft the small asterisk 10 which puts in action двухрядную a chain 9 drives of camshafts settles down also. On engine VR6 the asterisk 13 on the forward end of the cranked shaft, putting in action a single-row chain 14, is fixed (acts in film together with cranked shaft).
Set the tension двухрядной chains, a drive of camshafts, is carried out by the lamellar tension device of a chain (натяжителем) 8 which is regulated by means of the tension of a chain inserted outside of an adjusting bolt. The single-row chain between an asterisk 13 cranked shaft and an intermediate asterisk 11 also has the tension device 12 which is regulated in the hydraulic way and does not demand any additional intervention. It is necessary to remember that the tension device of a chain has the blocking adaptation which is necessary for unblocking before changing the tension device of a chain. The dvuhrjadnaja chain of a drive nestles outside inside for the account успокоителя 18 that prevents possibility of blow of a chain of a drive on camshafts. The single-row chain too nestles успокоителем 12, but the chain nestles from within outside. For fastening успокоителей bolts and special fingers are used.
