Varieties of Truck Parts in Automobile Industry
A truck, as we all know are large automobiles designed mainly for transportation purposes. Also called Lorry, these heavy motor vehicles are extremely powerful, and may be configured to mount specialized equipment, good examples being fire trucks, concrete mixers and suction excavators. In contemporary times, these mammoth powerhouses run either on gasoline or on diesel engines, with diesel dominant in commercial applications.
A typical Truck consists of the following main parts:
The chassis refers to the central framework including the engine, transmission, driveshaft, differential, and suspension that supports the entire coachwork, exactly like the skeleton of a living being. In a truck, the chassis contains all the essential parts of a truck (without the body) and is ready for operation on the road.
The cab, also referred to as the Cabin in certain countries, is the enclosed space where in the driver sits and operates the entire vehicle. Normally, a sleeper also accompanies the cab, so as to facilitate a resting place for the driver when not driving. A few cab configurations are described below:
Cab Over Engine (COE): Also called flat nose, this type is configured such that the driver is seated above the front axle and the engine. This design is almost ubiquitous in Europe, where overall truck lengths are strictly regulated, but also widely used in the rest of the world as well.
Conventional Cabs: Mostly seen in North America and Australia, the driver in this type of Cab is seated behind the engine, just like in normal passenger cars or pickup trucks. Conventional cabs are further classified into large car and aerodynamic designs. A "large car" or "long nose" is a conventional truck with a long hood. Aerodynamic cabs are very streamlined, with a sloped hood and other features to lower drag.
Cab Beside Engine: A rare design, this type of cabs are seen in trucks used inside shipping yards, or other specialist uses such as aircraft baggage loading.
Most modern trucks today run on a four stroke diesel engine with a turbocharger and after cooler. Very large off-highway trucks use locomotive-type engines such as a V12 Detroit Diesel two stroke engines.
A central shaft for a rotating wheel or gear, the axle is one of the most unalienable part of the truck. Secured or spline in fixed relation to the wheels, the axle not only empowers the wheels with driving torque but also helps to keep the position of the wheels consistent, relative to each other and to the vehicle body.
