4.3.1. The design description

Fig. 4.130. A drive shaft: 1 — the external hinge of equal angular speeds; 2 — the big collar; 3 — a protective cover; 4 — a small collar; 5 — a drive shaft; 6 — a small collar; 7 — a protective cover; 8 — the big collar; 9 — the internal hinge of equal angular speeds; 10 — the case of the internal hinge

The twisting moment from a transmission to driving wheels is transferred by means of drive shaft. Each shaft consists of three parts: internal and external hinges of equal angular speeds (SHRUS) and the shaft (fig. 4.130).

The shlitsevaja part of the external hinge is inserted into a nave of a wheel and fixed by a nut. SHRUS are greased консистентной with greasing which is replaced only at hinge dismantling.

Covers should be checked periodically on damages and greasing leak.

Greasing follows from the hinge at an impulse of a protective cover or easing of collars of fastening.

The torn protective covers of SHRUS immediately replace, damage of hinges differently is possible. Cover replacement includes removal of a shaft of a drive.

Vibration and the raised noise at трогании from a place, braking by the engine and on sharp turns arise at deterioration of hinges of equal angular speeds, шлицевых connections of a shaft and at easing of an inhaling of bolts of fastening of wheels.

Specifications of shaft of a drive are resulted in tab. 4.10.
