Steering shaft composite, consists of top 13 (pic. 183) and intermediate 20 shafts. The shaft 18 of the worm and the upper shaft 13 are interconnected by an intermediate shaft 20 with cardan joints at the ends. The hinges on needle bearings are one-piece.
Pic. 183. Steering:
1 - lateral thrust; 2 - bipod; 3 - medium thrust; 4 - pendulum lever; 5 - adjusting clutch; 6 - lower ball joint; 7 - right rotary fist; 8 - upper ball joint of the front suspension; 9 - right steering knuckle lever; 10 - upper shaft bearing; 11 - steering shaft mounting bracket; 12 - bracket pipe; 13 - upper steering shaft; 14 - pendulum arm bracket; 15 - axis of the pendulum lever; 16 - steering gear housing; 17 - shaft seal; 18 - worm shaft; 19 - universal joint; 20 - intermediate steering shaft; 21 - facing casing; 22 - switch lever for the wiper and washer of the windshield and the headlight unit; 23 - headlight switch lever; 24 - turn signal switch lever; 25 - steering wheel; 26 - fixing plate of the front end of the body; 27 - coupling bolt of the hinge; 28 - body spar.
The upper shaft is mounted in the tube of the bracket 11 on two needle bearings with rubber bushings. The bearings in the pipe are rolled. Bracket 11 is attached to the body panel bracket at four points: from below with bolts with fixing plates 26, from above - on welded bolts with nuts and washers.
In a head-on collision, the edges of the fixing plates are deformed and slip through the holes of the bracket 11. Due to the folding of the steering shaft, the steering wheel leaves the driver's chest area, which reduces the likelihood and severity of injury.
Worm shaft (this type of steering) has a great length. At the bottom of the worm shaft, as well as at the end of the crankcase 7 (pic. 184) of the steering mechanism, marks are made in the form of marks B and C, along which the bipod shaft roller is installed in the middle of the worm. When these marks are aligned, the steering wheel hub must be horizontal.
Pic. 184. Steering gear:
1 - plate of the adjusting screw of the bipod shaft; 2 - adjusting screw; 3 - locknut: 4 - plug; 5 - cover of the crankcase of the steering mechanism; 6 - worm; 7 - steering gear housing; 8 - bipod; 9 - bipod fastening nut; 10 - spring washer; 11 - bipod shaft seal; 12 - bushing; 13 - bipod shaft; 14 - bipod shaft roller; 15 - worm shaft; 16, 17 - worm bearings; 18 - shims; 19 - lower crankcase cover; 20 - roller axis: 21 - roller bearing; 22 - worm shaft seal; B, C - labels.
Due to universal joints on the intermediate shaft, it was no longer necessary to install shims between the steering gear housing and the body side member to adjust the alignment of the connected shafts. To reduce the force on the steering wheel, roller 14 is mounted on a double-row ball bearing 21.
Steering gear parts are interchangeable with other models of VAZ cars.
