Repair and car operation

Movement with the trailer

Movement with the trailer will show increased requirements both to the towing car, and to the driver.

The trailer limits manoeuvrability, ability to overcoming of liftings, dispersal and braking possibilities, influencing dynamic properties and controllability of the car.

About admissible weight of towed cargo and about a safe load on дышло you will find the data in Specifications. The admissible weight of towed cargo is specified also in the car passport. To consult about possibility of its increase it is possible on any СТОА BMW.

Tjagovo-coupling устройство*

If the tjagovo-drawbar is established at factory the car is equipped strengthened подвеской* the back bridge which compensates weight of the tjagovo-drawbar and optimises dynamic characteristics at movement without the trailer.

The optimum design of a running gear of your car guarantees high traffic safety and comfort, and also possibility of sports driving. The running gear allows to tow the trailer with the cargo, not leaving on weight for a limit resolved for the car in a serial complete set if thus you go with the trailer only in holiday or a bit more often, and your manner of driving corresponds to more difficult service conditions of the car.

At дооснащении the car tjagovo-coupling устройством* with a demountable spherical head it should have certification BMW. And its installation should be made technically competently on firm СТОА.

The demountable part of the tjagovo-drawbar with a spherical head should be covered консистентной by greasing; it facilitates its installation and dismantle.

At installation of the tjagovo-drawbar after release of the car from its factory also it is recommended to equip with the strengthened suspension bracket. It also is a condition for reception of the permission to movement (for some types of trailers) with большей in weight of towed cargo. Cars with a regulator of a road gleam to equip with the strengthened suspension bracket unessentially.

Other systems of a suspension bracket offered to free sale in system of trade by autoaccessories, have no certification BMW.

Tjagovo-drawbar installation limits a system effectiveness of the back bumpers absorbing energy of collisions on small speeds at the expense of elastic deformations.

Stabilising adaptations are recommended to be applied first of all at towage of heavy trailers. To consult about it it is possible on any СТОА BMW.

Cover of a nest for tjagovo-coupling устройства*

Before removal and installation of a spherical head the request to familiarise with the applied separate instruction.

At cover installation its groove should be inserted at first in directing, and then to press on the top part of a cover.

Safe load on a support дышла

It is a question of loading from which дышло the trailer presses on a spherical head of the tjagovo-drawbar. To define it it is possible, for example, floor household scales.

By the rules operating in Germany, this size should make a minimum of 25 kg.

The admissible size cannot be exceeded, its maximum use however is desirable.

The weight from which дышло the trailer presses on the support, influences behaviour of the car. Therefore at movement with the trailer admissible indicators of full weight of the car and loading on road from its back bridge should not be exceeded. Load-carrying capacity partially decreases because of subtraction from it weight of the tjagovo-drawbar. It should not be exceeded and an indicator of an admissible lump of the car with the trailer.

Loading

Trailer loading should be made so that cargo took places as it is possible more low and as it is possible more close to a bridge axis.
Fall of the centre of gravity of the trailer essentially improves traffic safety of the car with the trailer.
It is impossible to exceed indicators of a lump of the trailer and admissible weight of towed cargo. The smaller size is defining.

At trailer purchase it is recommended to request from the seller guarantee acknowledgement by the manufacturer of its actual weight and load-carrying capacity.

Movement on lifting

The size of an overcome bias (measured on a sea level) is limited 12 % for safety reasons and in order to avoid creation of hindrances to a transport stream, and at the increased weight of towed cargo (in the resolved cases) - 8 %.

From experience it is known that in process of height increase above sea level capacity of the engine falls. At movement on mountain roads it is necessary to remember, in particular, ability deterioration to троганию from a place on lifting in this connection it is necessary to refuse full use of admissible limits of weight of the car and the trailer.

Movement under a bias

The special attention is demanded by descents of roads. On an entrance to them it is necessary to be switched to a hill-climbing gear, if necessary up to the first (at complete set АТ a control lever is translated up to position 2) then on small speed to move under a bias.

The maximum speed

The maximum speed of movement with the trailer on roads is limited to 80 km/h. Admissible axial loading is defined so that at this speed is provided normal траекторная stability. Even if in other countries movement with higher speed is authorised, all the same for safety reasons it is not necessary to go faster.

Trailer influence can be eliminated only immediate braking.

Pressure of air in tyres

Pressure of air in car and trailer tyres should be a subject of special attention. For the trailer the norms established by its manufacturer are defining.

Rear-view mirrors

If at movement with the trailer the review sector through serially established external rear-view mirrors appears insufficient rules offer to establish instead of them two mirrors in which the driver can see the trailer to back edge of each of boards. Such mirrors, including with adjustable arms, you can get on СТОА BMW.

Electric equipment

By transportation the trailer-summer residence it is necessary to take into consideration the raised expense of the electric power. Therefore taking into account the limited capacity of the accumulator inclusion of consumers of a current should be short.
Before departure necessarily check work of back lanterns of the trailer.
