Trailers

As a follower (commonly also called tags) are vehicles that have generally do not have their own drive and behind a towing vehicle - such as Car Trailer, truck or bike (see bike trailer) - to be carried. Rail-followers are called wagons or Lore. Trailer transfer the load, primarily through the wheels on the road, down to the - for single-axle trailers - on the towing vehicle so-called oppressive load. The tensile forces are transmitted via the so-called pole by tractor to the trailer. A trailer hitch is the connection between the towing vehicle and a trailer or the connection between the supporters when multiple tags are attached to the towing vehicle. Types Of basic types are distinguished by the following supporters: Central-axle trailer Multi-axle trailer with a steerable

front axle Central-axle trailer (SDAH) These followers of the shaft is rigidly connected to the Annexes under. He possesses a rare or two axes (three), which are also rigidly connected to the frame. Nearly all Car Trailer are built as a central-axle trailer trailer. After approximated in the EU StVZO such an up to 750 kg gross vehicle weight is lighter than trailers (Class O1) and does not have its own brakes. From this total a brake is required. In Europe, this is an overrun brake in most cases. Trailer brakes are permitted up to 3500 kg gross vehicle weight. Heavier trailers require a continuous braking system. This is in Europe almost always an air brake. Most caravans are central-axle trailer with an axle or a tandem axle. Special tags are, for example, horse trailers, which are mainly designed as a tandem trailer. Here are offered depending on the intended use different suspension systems, such as rubber suspension axles, Drehstabfederachsen, rotary shear torsion axles. Multi-axis with a steerable front axle trailer These trailers have two or more axes, which is steered by the front axle. This is done almost exclusively on a turntable. These trailers are typical for trucks and tractors. Lately, for light long or volume of shipments also offer Car Trailer of this type. The permissible gross weight of up to 20 tonnes with two axles and 24 tons for more than two axles - with the exception of approval (flat bed trailer for heavy) and more. At the wheel steering the front axle is mounted on a turntable, and with the tiller firmly connected. The shaft is vertically movably mounted with heavy springs and kept as a security precaution. It should only be up at least 20 cm above the floor fall down, not to be damaged on impact with. Multi-axle trailers are usually equipped with air brakes. The body styles are similar to the truck, very versatile. Typical building types are the open box (bed)), the open box with a tarp and hoop and the closed box (box body. There are also many special designs that are tailored to the particular purpose.
