Trailer towage

The factory complete set of the car the tjagovo-drawbar provides also all necessary for trailer operation under technical and standard requirements.

For electric connection of the car and the trailer the car is completed with a 13-contact plug socket. At presence on the trailer of a 7-contact plug plug it is possible to use a corresponding cable available at enterprises Audi the adapter.

Additional installation of the tjagovo-drawbar should correspond to requirements of the manufacturer of the given device.

Maintenance instructions

Remember admissible maximum weight of towed cargo, Specifications see.

Weight of towed cargo

At all do not exceed admissible maximum weight of towed cargo.

If as much as possible admissible weight of the trailer is not used completely it is possible to overcome liftings with большей in bias size.

Standard values of weight of towed cargo are valid only at height to 1000 m above sea level. With height increase raises разреженность air and accordingly capacity of the engine and, as consequence, ability to overcoming of liftings decreases. Therefore the standard weight of the lorry convoy decreases on 10 % on each 1000 m of lifting. The weight of the lorry convoy is equal to the sum of weights (loaded) car and (loaded) trailer.

Data on the basic loading, specified in the factory tablet of the trailer, is its control sizes. The data which can be below these sizes, it is possible to find in registration documents of the car or in Specifications.

Cargo placing

Trailer cargo distribute so that the heaviest subjects settled down whenever possible more close to its bridge. Besides, fix cargo not to admit its displacement at movement.

The admissible basic loading transferred to a spherical head through дышло of the trailer, use whenever possible completely, but do not exceed.

Pressure in tyres

Establish pressure in the car tyres, corresponding to its total load, see the tablet of pressure of air in tyres a door rack. If necessary modify also pressure of air of tyres of the trailer according to recommendations of its manufacturer.

External mirrors

If serial rear-view mirrors do not provide the sufficient back review, it is necessary to establish additional external mirrors. Both external mirrors should fasten on put arms. So adjust position of mirrors that the sufficient back review was provided.

Headlights

Prior to the beginning of movement with the trailer check up and if necessary modify installation of headlights by means of the device of regulation of an angle of slope of headlights, Illumination and review maintenance see.

Demountable spherical head

The demountable spherical head of the tjagovo-drawbar of a factory complete set is together with an erection manual in a niche of a spare wheel of a luggage carrier.

Instructions but to driving

Movement with the trailer demands extra care.

  • Do not tow the loaded trailer not loaded car.
  • Do not move with the maximum speed, especially at movement under a bias.
  • In due time brake.
  • At high external temperature watch indication of temperature of a cooling liquid.

Loading distribution

At the empty car and the loaded trailer extremely adversely distribution of loading. In need of movement in the given variant movement should be especially slow.

Speed

With increase in speed dynamic properties of the lorry convoy worsen. Therefore under adverse road, weather and aerodynamic conditions do not use resolved by traffic rules the maximum speed. It especially concerns movements under a bias.

At once reduce speed at the slightest signs of wagging of the trailer. Do not try to "level" at all the lorry convoy increase in speed.

Brake in due time! At towage of the trailer with inertial brake system brake in the beginning softly, and then smoothly. It will help to avoid pushes the blocked wheels of the trailer. For use of possibility of braking by the engine, be in due time switched to a hill-climbing gear.

Stabilising adaptations reduce fluctuations of the trailer concerning a cross-section axis and its wagging. It is recommended to apply them at considerable weight of the trailer.

Overheat

Watch indication of temperature of a cooling liquid at very high external temperature and movement on long lifting on a hill-climbing gear and with high frequency of rotation of a shaft of the engine, Controls and devices see. At arrow calling on the right part of a scale at once reduce speed. At a blinking in a control panel of an alarm lamp stop and cool the engine, having allowed to it to work as some minutes idling.

The demountable tjagovo-drawbar

Introduction

Installation and dismantle of the tjagovo-drawbar demands accuracy.

The demountable spherical head of the tjagovo-drawbar is under a luggage carrier flooring.

  • Cars with a spare wheel.

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

Use of hinged components/autoaccessories on the tjagovo-drawbar

Remember that at use of the improper hinged components mounted on the tjagovo-drawbar (for example, an arm for a bicycle), probably latent damage of a spherical head that in an extreme case can lead to destruction of the tjagovo-drawbar during trailer towage.

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 check up correctness of closing by a cover of a fixing nest.

At car cleaning by the steam-ejecting pump remove preliminary spherical head and check up correctness of closing of a fixing nest a cover.

Installation of a spherical head (the first stage)

 PERFORMANCE ORDER

  1. Under a bumper completely open a cover of a fixing nest. The cover is automatically fixed in the given position.
  1. Check up probability of pollution of a fixing nest and if necessary clean it.

Continuation, see «Installation of a spherical head (the second stage)».

Installation of a spherical head (the second stage)


The spherical head should be pure and without damages

 PERFORMANCE ORDER

  1. Check up probability of pollution and clamp damage (A), an uncoupling finger (B), cases of a spherical head in a place of contact to a fixing pipe, and also a flywheel.


The spherical head should be mounted with a preliminary tightness

The demountable tjagovo-drawbar: a spherical head with the case

The preliminary tightness is provided with performance of following conditions:

  • The red label of a flywheel is in a zone of a black label of the case of a spherical head.
  • The clamp (B) is drowned in an aperture 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 (C).

The spherical head can be established only with a preliminary tightness.

Continuation, see «Installation of a spherical head (the third stage)»
