Trailer operation

THE GENERAL DATA

At movement with the trailer loading on the car, in comparison with a usual mode of movement, increases. Requirements to the driver raise also.

At trailer towage dynamic qualities of the car strongly change. Ability to overcoming of liftings, efficiency of dispersal and braking, and also manoeuvrability and stability on turns in particular worsens.

The mode and speed of movement should get out according to the specified changes.

Specifications

The factory complete set of the car the tjagovo-drawbar provides a 13-contact plug socket. At presence on the trailer of a 7-contact plug plug it is possible to use available on HUNDRED Audi a cable-adapter.

Service regulations

Stabilising adaptations reduce fluctuations of the trailer concerning a cross-section axis and its wagging. Therefore we recommend to use the given adaptations (especially at the big weight of the trailer). Stabilising adaptations are available on HUNDRED Audi, and their installation in the same place can be executed.

At all do not exceed admissible maximum weight of towed cargo, address to Specifications.

With the weight of towed cargo resulted in Specifications it is possible to overcome liftings with size of a bias to 8 – 12 %. If as much as possible admissible weight of the lorry convoy is not used completely it is possible to overcome liftings with большей in bias size.

As much as possible admissible weight having on a spherical head of the tjagovo-drawbar from дышла of the trailer, use probably more full, but do not exceed, address to Specifications.

Standard values of weight of towed cargo are valid only at height to 1000 m above sea level (NN). With height increase raises разряженность air and accordingly capacity of the engine and as consequence ability to преодолеванию liftings decreases. Therefore reduce weight of the lorry convoy by 10 % through each 1000 m of lifting.

Taking into account admissible maximum weight of towed cargo and loading having on the tjagovo-drawbar distribute luggage so that the heaviest subjects settled down whenever possible more close to its axis. Besides, fix cargo not to admit its displacement at movement.

Data about weight of towed cargo and the loading having on the tjagovo-drawbar, specified in the factory tablet of the trailer, is its control sizes. Nameplate data which can be below the given sizes, it is possible to find in the documentation of the car or in the given management.

Establish pressure in the car tyres, corresponding to its full loading. Thus check up also pressure of tyres of the trailer.

Demountable tjagovo-coupling устройство*

The demountable spherical head of the tjagovo-drawbar is in a niche of a spare wheel.

For installation / dismantle of a spherical head enough normal efforts of hands.

ATTENTION

Never use for installation / dismantle of a spherical head auxiliary means or tools since it is possible to damage the lock mechanism therefore reliable operation of the tjagovo-drawbar will not be guaranteed.
Modification of a design of a spherical head and other components of the tjagovo-drawbar, and also their repair is not supposed.
At occurrence of difficulties in using etc. address on HUNDRED Audi.
Before each trip check correctness of fixing of a spherical head.
Never deblock a spherical head at the attached trailer.
At movement without the trailer remove a spherical head and establish заглушку in a fixing pipe.
After that lay the tjagovo-drawbar in a niche of a spare wheel.
At car cleaning by the steam-ejecting pump remove a spherical head and establish in a fixing pipe заглушку.



Installation of a spherical head


From the fixing pipe located under a bumper (1) take заглушку (2).

Check up probability of pollution of a fixing pipe and if necessary clean it.
ATTENTION

Necessarily remove pollution. Otherwise under certain circumstances a spherical head it will not be reliable to be fixed in a fixing pipe!




Open a luggage carrier and from a niche of a spare wheel take a spherical head.

Check up probability of pollution and damage of the case of a spherical head to a place of contact to a fixing pipe (), and also uncoupling рычажка () and handles ().


Spherical head mount only with a preliminary tightness. Therefore check up a tightness of a spherical head.
The preliminary tightness is provided with performance of following conditions:

The white label () handles is in a zone of a red field of the case of a spherical head.

Lock balls () are drowned in apertures of the case of a spherical head.

The handle that is well visible visually, is on certain distance from the case of a spherical head so between the handle and the case of a spherical head there is a backlash ().


In the absence of a tightness of a spherical head the following is necessary:

Insert into the lock of the handle a key (1) and turn it to the left.

Pull the handle in the specified direction And and turn in the extended position in the direction specified by an arrow In till the moment of fixing splitting рычажка (2).
ATTENTION

Operation of a spherical head if it is not possible to reach its tightness according to the aforesaid is not supposed. Address on HUNDRED Audi.




Establish a spherical head with a tightness in a fixing pipe and wring out upwards in the direction specified by an arrow.
ATTENTION

At hand installation should not be in a handle zone – probably травмирование!



Fixing process is carried out automatically. Click should be thus distinctly audible.

Lock a spherical head (turn a key to the right) and take a key.

The control of reliability of fastening


After installation, for the purpose of safety, check up correctness of fastening of a spherical head.

Correctness of fastening is provided with performance of following conditions:

The white label () handles is in a zone of a green field of the case of a spherical head.

The handle adjoins to the case of a spherical head. As a result between the handle and the case of a spherical head (arrow) there is no backlash.

The spherical head is locked also a key is taken (the handle is not extended).

The spherical head reliably sits in a fixing pipe (check up, подвигав her hand).
ATTENTION

At default of the conditions set forth above repeat installation.



Even at default of one of conditions there is a danger of accident and tjagovo-drawbar operation is not authorised.

In this case address on HUNDRED Audi.

Plug socket of the trailer



The plug socket for pressure giving on the trailer is behind the buffer.

For connection of a plug plug of the trailer take away in the direction specified by an arrow downwards the handle () the car.

Dismantle of a spherical head


Insert into the lock of the handle a key (1).

Unlock a spherical head (turn a key to the left).

Strong keep the case of a spherical head and pull the handle in the direction specified by an arrow And. In summary turn the handle in the extended position against the stop in the direction of Century specified by an arrow

Release the handle. It is fixed independently with a tightness.

Lock the handle (turn a key to the right) and take a key.

Spherical head lay in a niche of a spare wheel.

Take away upwards a plug socket of the car.
ATTENTION

If the tjagovo-drawbar is not maintained long time for the purpose of unloading of elements of a spring of a spherical head the lock mechanism should be released.

For this purpose turn the handle to the left.

At hand dismantle should not be in a handle zone – probably травмирование!



In a fixing pipe (1) establish заглушку (2).
ATTENTION

Necessarily establish заглушку. Otherwise, owing to pollution, there is a probability of that a spherical head it will not be reliable to be fixed in a fixing pipe!
