Trailer operation

GENERAL INFORMATION

At movement with the trailer load of 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 maneuverability 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 traction coupling device provides the 13-contact plug socket. At existence on the trailer of a 7-contact plug fork it is possible to use a cable adapter available on HUNDRED Audis.

Service regulations

Stabilizing adaptations reduce fluctuations of the trailer of rather cross-section axis and its wagging. Therefore we recommend to use these adaptations (especially at big mass of the trailer). Stabilizing adaptations are available on HUNDRED Audis, and their installation in the same place can be executed.

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

With mass of towed cargo specified in Specifications it is possible to overcome liftings with bias size to 8-12 %. If the most admissible mass of a road train is not used completely, it is possible to overcome liftings with bigger size of a bias.

The most admissible weight falling on a spherical head of the traction coupling device from дышла of the trailer, use probably more fully, 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 increase in height the razryazhennost of air raises both respectively engine capacity and as a result ability to a preodolevaniye of liftings decreases. Therefore reduce mass of a road train by 10 % through each 1000 m of lifting.

Taking into account admissible maximum weight of towed cargo and loading falling on the traction coupling device distribute luggage so that the heaviest subjects settled down whenever possible closer to its axis. Besides, fix cargo not to allow its shift at movement.

Data on mass of towed cargo and the loading falling on the traction coupling device, specified in the factory plate of the trailer, are its control sizes. Passport data which can be below these sizes, it is possible to find in documentation of the car or in this management.

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

Demountable traction and coupling устройство*

The demountable spherical head of the traction coupling device 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 supportive applications or tools since it is possible to damage the lock mechanism therefore reliable operation of the traction coupling device will not be guaranteed.
Modification of a design of a spherical head and other components of the traction coupling device, and also their repair is not allowed.
At emergence of difficulties in using etc. address on HUNDRED Audis.
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 a cap in a fixing pipe.
After that lay the traction coupling device in a niche of a spare wheel.
When cleaning car by the steam-ejecting pump remove a spherical head and establish in a fixing pipe a cap.



Installation of a spherical head


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

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

Surely remove pollution. Otherwise under certain circumstances the spherical head will reliably not be fixed in a fixing pipe!




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

Check probability of pollution and damage of the case of a spherical head to a place of contact to a fixing pipe (And), and also uncoupling a rychazhka (In) and handles (C).


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

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

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

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


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

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

Pull the handle in the specified direction A and turn in the extended situation in the direction B specified by an arrow till fixing splitting a rychazhka (2).
ATTENTION

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




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

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



Process of fixing is carried out automatically. Thus click should be distinctly audible.

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

Control of reliability of fastening


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

Correctness of fastening is provided with performance of the following conditions:

The white label (And) 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 (shooter) there is no gap.

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

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

At default of above-mentioned conditions repeat installation.



Even at default of one of conditions there is a danger of accident and traction coupling device operation is not authorized.

In this case address on HUNDRED Audis.

Plug socket of the trailer



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

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

Dismantle of a spherical head


Insert into the handle lock a key (1).

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

Strong hold 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 situation against the stop in the direction B 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 up the plug socket of the car.
ATTENTION

If the traction coupling device is not maintained a 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 dismantle of a hand should not be in a handle zone – probably travmirovany!



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

Surely establish a cap. Otherwise, owing to pollution, there is a probability of that the spherical head will reliably not be fixed in a fixing pipe!
