Trucks are commonly utilized for commercial trade and transport of goods and commodities. They are also having wide acceptance as a form of urban and off-road transport. These functions are attributed to the durability and sturdiness of the vehicle. At present more and more manufacturers are taking keen attention to making mechanisms and accessories that will not only pump up the power of the vehicle but also lift its image and sparkle. Now change is a good thing especially if it’s for the better but let’s go old school just a bit and set aside the accessories en route to an anatomical breakdown of the truck.
Before you personalize your very own heavy duty machinery, you must first be acquainted with the basic set-up of this vehicle. Trucks are of common structures and designs and are usually built with a chassis, a cab, a cargo placement portion, suspension and wheels, axles, drivetrain, and of course the one that makes it run, the engine. There are also systemic mechanisms that ensure the good performance of the vehicle. These are water, electrical, pneumatic, and hydraulic systems.
It’s time to kick things off with the cab. This is considered the driver’s space. It can be described as an enclosed area wherein the driver finds a place to sit on. There is a compartment called a sleeper which is commonly attached to the cab. This serves as the driver’s resting cabin when he is not driving. There are three types of cabs used for trucks. The cab over engine or flat nose situates the driver on top of the engine and the axle while the conventional cabs let the driver seat behind the engine. There is also a rare type in which the engine is placed beside the cab.
It is said that the oldest truck was built by a guy named Gottlieb Daimler in 1896. During the past medium-duty trucks such as SUVs and pickups found in North America and Russia normally utilize gasoline engines but at present diesel designs and models are being widely embraced as evidenced by current truck classes of three to eight GVWs. The heavier forms of trucks are commonly powered by four stroke turbo intercooler diesel engines while off-highway types prefer the utilization of a V12 Detroit Diesel two-stroke engines.
Truck transmissions vary according to the size of the vehicle. Smaller trucks have the same kind of transmission system found in almost all cars which can either be manual or automatic and equipped with synchronisers. The bigger and more powerful forms of trucks are commonly driven using manual transmissions but without synchronisers. These transmission forms are identified as crash boxes wherein the double-clutching technique for shifting is needed. Since double clutching normally ends up in repetitive motion injuries, floating is also employed in transmissions that do not have synchronisers. This method allows gear shifting without the use of clutch except during the starting and stopping of the vehicle.
The frame of a truck is commonly composed of two parallel boxed or C-shaped rails that are held together by cross members and is commonly known as ladder frames due to its similarity with a ladder. The rails have two shorter horizontal flanges and a tall vertical section. The height of the vertical segment is needed in order to provide beam resistance.
Accessories offer an exciting and educating exploration of vehicles and automobiles but it’s always better to know your truck inside and out before embarking on such deed.
