Steering

GENERAL INFORMATION

The Reechny steering mechanism with drafts

1–tip of steering draft
2–nut, 50 N • m
3–collar. Surely replace
4–protective cover. Do not remove after convergence adjustment. It can be replaced only after removal of the steering mechanism (work HUNDRED).
5–collar. Surely replace
6–steering draft, 75 N • m. It can be replaced only after removal of the steering mechanism (work HUNDRED).
7–a collar with rubber
8–returnable pipeline
9–nut, 22 N • m
10-a collar with a rubber support. In the provision of installation of the shooter on a collar looks in the movement direction. In the presence of damages to a carving of a privarny nut a collar replace.

11-thermofilter
12-nut, 45 N • m. Being self-stopped, surely replace.
13-support of a drive of switching. At installation with the thermofilter – 11–(arrow A) should be aligned on a branch pipe.
14-bolt, 24 N • m
15-consolidation
16-hydraulic pipeline
17-hollow bolt, 45 N • m М16 х1.5
18-hollow bolt, 40 N • m М14 x 1.5
19-sealing ring. Surely replace
20-steering mechanism

The power steering pump with the holder. Execution with the bottom arrangement

1–holder
2–bolt, 25 N • m
3–hollow bolt, 30 N • m
4–pressure head pipeline
5–sealing ring
6–a soaking-up hose
7–collar
8–pump of the hydraulic booster. Before removal it is necessary to fill

oil. For this purpose pour in oil in soaking-up branch pipe of the pump and turn a nave a hand so that oil left from pump forcing.
9–pulley
10-the screw with an internal shestigrannik, 25 N • m
11-maple belt
12-tension device of a maple belt

The power steering pump with the holder. Execution with the top arrangement

1–holder
2–bolt, 25 N • m
3–pump of the hydraulic booster. Before removal it is necessary to fill with oil. For this purpose pour in oil in soaking-up branch pipe of the pump and turn a nave a hand so that oil left from pump forcing.
4–sealing ring. Surely replace.
5–hollow bolt, 30 N • m
6–pressure head pipeline

Operating movements of the driver are transferred from a steering wheel through a steering column and the steering mechanism to wheels. A steering column – safety, with height adjustment within 44 mm and a departure (length) within 50 mm.

The effort which is necessary for putting to a steering wheel at its rotation, especially on the standing car, decreases by means of the hydraulic amplifier of a wheel. The power steering consists of the oil pump, the tank and oil pipelines. The pump is actuated from the engine through maple a belt. The pump sucks in oil from the tank and submits it under pressure to the case of the valve of management. The case of the valve settles down in the steering mechanism. It is mechanically connected with the steering mechanism and submits oil depending on an angle of rotation of a steering wheel to the corresponding cavity of the hydrocylinder. Here oil influences the piston with a gear lath and supports thus wheel moving.

In a steering wheel the safety cushion settles down. It represents the combined air bag which in case of face-to-face collision is inflated and, thus, protects the head of the driver and the top part of a trunk from blow about a steering wheel. At face-to-face blow of the corresponding force by means of the control unit the small charge in the block of a safety cushion ignites and the gases which were formed thus inflate an air bag during several milliseconds. It is enough this time for damping of a trunk of the driver moving forward. Within several seconds after that the safety cushion is again compressed, since gases leave pillow openings.

ATTENTION

Carrying out welding and leveling works on steering elements is not allowed. Being self-stopped nuts replace with the new.
Along with a safety cushion of the driver there is also a safety cushion of the forward passenger and lateral safety cushions in front and behind. If on a place of the forward passenger in the direction, the return to movement, the children's seat is established, it is necessary деактивировать a safety cushion of the forward passenger. This work can be executed only HUNDRED AUDIS. Besides, on a door beam, a solar peak or the dashboard on the right side of the car there should be the corresponding precautionary sign «Seats for the child ahead is not present», differently at control by traffic police the driver can be fined.

At the car equipment a lateral safety cushion to backs of seats apply only the special upholstery resolved by AUDI firm.

At removal and installation of the block of a safety cushion

PERFORMANCE ORDER

1. Disconnect a negative cable (-)) the storage battery at the switched-off ignition. Attention: Thereof information from electronic blocks of memory, as, for example, a radio receiver code is erased. Without a code the radio receiver can be included only by the manufacturer or HUNDRED AUDIS. Therefore familiarize with subsection materials Input of a code of a radio receiver.
2. Isolate a negative pole (-)) the battery battery room to exclude possibility of casual contact.
3. Establish wheels directly. ATTENTION If the provided remarks are not observed, at further operation it can lead to failure of system of a safety cushion.

General comments

– After electric accession of a safety cushion before connection of the storage battery include ignition, the ignition key in the situation "Movement".
– At connection of the storage battery stay in salon of the car of extraneous people is not allowed.
– After removal of a safety cushion store it so that the soft party specified upward.
– If in work the break becomes, it is impossible to leave a safety cushion without supervision.
– It is not necessary to assort the safety cushion block. In the presence of malfunction it will be replaced completely. As the pillow contains explosive, it is necessary to store it reliably. Utilization of a pillow should be carried out HUNDRED AUDIS.
– A safety cushion check only in conditions HUNDRED. By no means it is impossible to apply a control lamp, the voltmeter or an ohmmeter to pillow check.
– Do not subject a pillow to liquid influence, in particular, greasing either what – or cleaners.
– If the pillow was dropped on a firm covering, it cannot be applied more
