An articulated vehicle is a vehicle which has a permanent or semi-permanent coupling in its construction. This coupling works as a large pivot joint , allowing it to bend and turn more sharply. There are many kinds, from heavy equipment to buses , trams and trains .
Given the Spanish Army's opinion that the FT was limited in firepower, the Trubia tank featured a special turret. The turret was designed in two articulated halves, which could traverse independently, each armed with a machine gun. Theoretically, if one of the machine guns jammed, the tank would still have another one to defend itself with.
Articulated passenger cars are becoming increasingly common in Europe and the US. The passageways between the car elements are permanently attached. There is a safety benefit claimed that if the train derails, it is less likely to jackknife and modern construction techniques prevent telescoping. Articulated cars are not, however, a new idea.
Tracked articulated vehicles typically steer by actuating the linkage connecting the cars of an articulated tracked vehicle. This linkage, called the train joint, uses hydraulic actuators [1] to position the front vehicle in an opposing direction to the rear one, and curves the direction of travel this way. [2]
The M520 "Truck, Cargo, 8-ton, 4x4", nicknamed Goer, truck series was formerly the US Army’s standard heavy tactical truck before its replacement by the Oshkosh HEMTT.As trucks go, the Caterpillar-made Goer stands out due to being articulated, much wider than other trucks, and lacking suspension on the wheels.
A less common variant of the articulated bus is the bi-articulated bus, where the vehicle has two trailer sections rather than one. Such vehicles have a capacity of around 200 people, and a length of about 25 m (82 ft); as such, they are used almost exclusively on high-capacity, high-frequency arterial routes and on bus rapid transit services.
The vehicle usually has all-wheel drive and consists of two basic units: the front section, generally called the tractor, and the rear section that contains the dump body, called the hauler or trailer section. Steering is made by pivoting the front in relation to the back by hydraulic rams.
This is unlike the more common solution with an articulation resting on a special connecting bogie, called jacobs bogie. Seen from the side at ground level, the suspended joint seems to be 'floating' because the lack of wheels directly under the joint. The shortest examples consist of two sections.
