Articulated vehicle

Articulated vehicle or articulated vehicle hot vehicles, which consist of several connected articulated, operationally inseparable parts, one passing through the joint is possible while driving. Typically, a hub in the region of the joint is provided for this purpose, which necessarily so adjusts itself that the angle between the longitudinal axis of the two parts of the vehicle and the longitudinal axis of the turntable always are both the same. The skin in the area of ​​the joint must be able to deform elastically and is therefore normally performed as a bellows. In order to improve the brightness of the car interior, transparent bellows are tested lately.

Joints are provided to make vehicles curves or hilltops and reduce common, without having to disassemble into several separate parts. If it 's all about the curve- maintenance a rigid in the vertical pivot joint; in practice, the two vehicle parts usually have to raise against each other and cut ( " nodding " ) can. The hinge structure itself consists in Busgelenken classic example of two approximately triangular components, which (partly elastic ) been mounted on the two vehicle parts and are connected in the middle by the actual joint. You are connected to each other by bending damper. A distinction " Pusher " - and " pullers " hinges; in the former the front of the car is pushed by the rear drive car, pulled from the front of the car in the latter the rear car. The conventional length of a joint are about 1.6 m; currently a short Pushergelenk is developed, the crossing by an entirely different principle with two on either side movable hinged trusses works and is about 60 cm shorter, which corresponds to a normal city bus an additional row of seats.

Many buses and coaches (especially city buses, lately also intercity buses ) are articulated buses, as well as numerous trolley buses are run as a joint trolleybuses. Likewise, modern light rail and full- rail units are almost always articulated. Here, buses and trolleybuses have a normally, in rare cases, two joints, mainline rail cars and rail units, however, often have far more joints (up to six ), the latter to meander through the narrow curves, maxima and minima on tram routes, for example, in town centers to be able to.

Not to be confused with articulated vehicles are rail vehicles, which consist of several close-coupled devices (eg, S-Bahn railcar class 420 ). Here is an operational separation of the individual cars is possible.

There are some non-powered articulated cars in rail transport; most of them are wagons, but it has also been joint dining car and, with trams also Gelenkbeiwagen.
