Any vehicle, regardless of its type and purpose, consists of three main parts: engine, body and chassis. The chassis of the car is a system consisting of assembled parts of the running gear, transmission and control mechanism. It is one of the most important parts of the vehicle, as it allows for the perception and transmission of all the forces that act on it while driving.
The undercarriage suspension elements reduce loads and compensate for vibrations when driving on bumpy roads and off-road. The subframe allows you to install a body, engine and other units on the chassis. The front and rear axles transmit rotational movement through the wheels and thus ensure the movement of the car.
The first cars produced in the last century had some difference from those that today drive on the roads. All cars - both cars and trucks - used to have a frame on which all units and components (body, transmission, engine, etc.) were installed. Over time, the frame chassis of the car remained only with trucks and buses. In passenger cars, the functions of the frame began to performbody.
Thus, two different vehicle chassis layouts can be distinguished.
Frame chassis, which generally consists of several strong beams on which all vehicle components are mounted. This design allows the vehicles to carry large loads and easily cope with various dynamic loads.
- Bearing body. In pursuit of lighter weight passenger cars, all frame functions were redefined to bodywork. This frame does not allow you to move large loads, but at the same time provides more comfort and speed.
Depending on the purpose of the car, the following types of structures can be used:
Spar frames are considered the most common. They are two longitudinal beams connected by crossbars. The shape of such beams can be completely different: tubular, X- or K-shaped. In the most loaded part, the frame has an enlarged channel section. The parallel scheme of spars (beams are located at an equal distance along the entire length of the chassis) is used on trucks. In off-road cars, side members can be used, which havesome divergence of the axes in both the horizontal and vertical planes.
The spinal frame is a single supporting longitudinal beam, on which the crossbars are attached. Often this beam has a circular cross section, so that it can accommodate transmission elements. Such a frame provides greater torsion resistance than spars. Also, the use of a backbone-type chassis implies the use of an independent suspension of all wheels.
The fork-spine frame has a branching of the longitudinal beam in the rear or front. That is, it combines spars and a spinal beam.
Other types of chassis frame are not used for trucks.
Other meanings of the term
In addition to the definition above, the word "chassis" can be used to describe self-propelled vehicles designed to install various machines and mechanisms. Also, this term is used for that part of the aircraft that is used to move along the airfield, take off and land. As in the case of the chassis of a car, this part softens the shocks and loads during the ground movement of aircraft. Aircraft landing gear, unlike automobiles, can be designed with wheels, skis or floats.
Often the meaning of the word chassis is confused with the concept of driving a car. The misinterpretation of the terms is due to the fact that they refer to almost the same part of the vehicle. Car owners freely say that their car has a 4x2 chassis. But at the same time it shouldunderstand that 4x2 is just a layout diagram from which you can find out the number of driving wheels, but no more. The same thing as a chassis has already been said above. Even though wheels and drive are part of the chassis system, it is inappropriate to use the term for such a narrow description only.
Types of pendants
The car chassis can have different types of suspension:
- on longitudinal springs;
- with twin guide levers;
- with two trailing arms;
- with drawbar;
Suspensions are equipped with levers, gaskets, shock absorbers and springs. The main purpose of this vehicle assembly is to absorb vibrations and vibrations while driving. The front and rear suspensions are different because the design of the steerable wheels requires more complex components.
New suspension, gearbox, steering, brakes, interior, body design and, of course, a modern Niva-Chevrolet engine - GM knows how to surprise its Russian consumers. This happened for the first time at the beginning of the 2000s and is expected again in 2016, after the start of the expected mass production of Chevy-2

It has long been known that it is impossible to clean a car from heavy dirt with plain water. No matter how hard you try, you still can't achieve the desired purity. In order to remove dirt from hard-to-reach places, special chemical compounds are used to reduce surface activity. However, they also cannot reach very small cracks and corners
Since the mid-60s, the Kharkov Plant of Tractor Self-Propelled Chassis (KhZTSSH) has been producing self-propelled chassis T 16. In total, more than 600 thousand copies of the machine were produced. For the characteristic appearance of the chassis, it had common nicknames in the USSR "Drapunets" or "Beggar"
The Marusya sports car dates back to 2007. It was then that VAZ was offered the idea of creating the first racing car in Russia
Probably every driver has faced such a problem as a dead battery. This is especially true in winter cold. In this case, the problem is most often solved by "lighting up" from another car
