1.6.15. Movement with the trailer
The tjagovo-drawbar should correspond to certain requirements.
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 between the car and the trailer the car is completed with a 13-polar plug socket. At presence on the trailer of a 7-contact plug plug it is possible to use a corresponding cable-adapter available at enterprises Audi.
Poslezavodsky installation of the tjagovo-drawbar should correspond to requirements of the manufacturer of the given device.
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 разряженность air and accordingly capacity of the engine and, as consequence, ability to преодолеванию liftings decreases. Therefore to reduce weight of the lorry convoy by 10 % through each 1000 m of lifting. The weight of the lorry convoy is the sum of weight (loaded) car and weight (loaded) trailer.
Data on the basic loading, specified in the factory tablet of the tjagovo-drawbar, is its control sizes. The data which be frequent can below these sizes, it is possible to find in registration documents of the car.
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 to use whenever possible completely, but not to 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 to modify also pressure of air of tyres of the trailer according to recommendations of its manufacturer.
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.
Prior to the beginning of movement check up at the attached trailer and if necessary modify installation of headlights by means of the device of regulation of an angle of slope of headlights.
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.
At intensive operation of the trailer it is recommended to a thicket to pass maintenance service, than it предусмотренно the service book.
Movement with the trailer demands extra care.
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 lower speed at the slightest signs of fluctuations of the trailer concerning a cross-section axis. Do not try to "level" at all the lorry convoy increase in speed.
Brake in due time At 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 movement under a bias should be anticipated timely switching on a hill-climbing gear. Stabilising adaptations reduce fluctuations of the trailer concerning a cross-section axis and its wagging. Therefore it is recommended to use the given adaptations (especially at the big weight of the trailer).
Fig. 1.156. The scheme of distribution of loading of hinged components and accessories
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. At arrow calling on the right part of a scale at once lower speed. At a blinking in a combination of devices of an alarm lamp stop and cool the engine, having allowed to it to work as some minutes idling.
At use of hinged components and accessories (for example, arms for bicycles) it is necessary to take into consideration the mentioned below information.
As much as possible admissible start (ledge) of an accessory / a hinged component of a spherical head should not exceed 700 mm.
As much as possible admissible full weight (bearing system, including useful loading) makes 75 kg.
The maximum useful loading depends on a site of the centre of gravity.
With increase in distance of the centre of gravity of useful loading concerning a spherical head the admissible full weight decreases.
Following values are supposed:
– At distance of 300 mm value of full weight (including bearing system) makes 75 kg;
– At distance of 600 mm value of full weight (including bearing system) makes 35 kg.
Use only arms for bicycles on which it is possible to mount a maximum three bicycles is supposed.
Use of hinged components and accessories on the tjagovo-drawbar
It is recommended use only the hinged components authorised by concern Audi (for example, кроштейны for a bicycle). If other hinged components are used, be convinced that they are authorised by the manufacturer of hinged components for use on a spherical head. At use of improper hinged components probably damage of the tjagovo-drawbar. In a damage extreme case can lead to tjagovo-drawbar destruction.
