For any car owner, whether an experienced driver or a newbie who has just obtained a license, understanding the machine goes far beyond the ability to steer. Often in conversations with masters at the service station, when buying spare parts or discussing an accident, it is necessary to accurately identify the damaged or interesting element. Misunderstanding the basic terminology can lead to curious situations where the client asks to replace the โfront ironโ with a specific detail that the mechanic will misunderstand.
The body of a modern car is a complex engineering structure consisting of dozens of welded and removable elements, each of which has its own strictly defined name. Knowing these names helps not only to communicate competently with specialists, but also to better understand the logic of the safety systems, aerodynamics and overall strength of the machine. In this article we will discuss in detail, What are the names of the car body parts?Dividing them into logical groups for ease of perception.
We will walk from the front of the car to the back, paying attention to both the exterior panels and the hidden power elements that form the โskeletonโ of your vehicle. This knowledge will become the foundation for further study of auto repair and operation.
General architecture and power frame
Before we move on to the hinged elements that we see daily, it is necessary to understand the base. Most modern passenger cars are built according to the scheme load-body. This means that the car does not have a separate frame like trucks or old SUVs. The entire load is taken on by the body box itself, consisting of stamped metal panels connected by welding.
The main force elements here are spars. These are powerful beams running along the bottom of the car in front and behind. They take the main blow in a head-on collision, deforming and quenching the energy of the impact so that it does not pass to the passenger compartment. Damage to spars is considered critical and often makes the car unsuitable for safe operation without the most difficult recovery on the slip.
โ ๏ธ If after a serious accident the geometry of the spars is broken, the car can take to the side even on a flat road, and the tires will wear out unevenly. Checking the geometry of the body is mandatory!
Connect the spars and form the rigidity of the crossbar and central racks. The floor of the car is also part of the power kit, especially in the tunnel area, where fuel lines and exhaust system elements are often laid. Understanding this architecture is important as it is in the repair process. Recovery of the geometry of the power elements is more important than replacement of the outer skinIt is the life of the people in the salon that depends on them.
Hinged elements such as doors, trunk lid and hood, do not apply to power set. They are mounted on hinges and serve to access the inside and protect the contents. However, their proper adjustment directly affects aerodynamics and noise insulation.
Front of the car: nose and protection
We begin the detailed examination with the "face" of the car. The most prominent element here is bumper. Contrary to popular belief, in modern cars it is primarily a decorative and aerodynamic element, often made of plastic. Behind it hides a metal reinforced bumper beam, which should take a hit. Under the bumper is often located spoiler Or a skirt that improves streamlinedness.
On the sides of the bumper and radiator grille are the front wings. These are removable panels that cover the wheel arches in the front. In small accidents, the wings are often changed entirely, since their reeching is economically impractical. Between the wings, under the hood, there is a cooling radiator and other units closed from dust and down with a special grille or grille.
- ๐ hood - removable cover covering the engine compartment from above; usually has heat and noise insulation on the inside.
- ๐ก๏ธ Sprays - are installed behind the wheels to protect the lower part of the body from flying from under the wheels dirt and stones.
- ๐ก Optics Headlights that can be integrated into the body or bumper, being an important element of the design.
An important element of the front part is also television (or front panel). This is a metal cross, to which the upper supports of shock absorbers, radiators and the hood lock are attached. With strong impacts in the front of the TV can be deformed, which will require serious body repairs.
Side projection: doors, racks and sills
The side of the body is the area we interact with most often when we get in and out of the car. The main elements here are the doors. The car door is a complex design consisting of an external panel, an internal frame, glass and mechanisms. Between the front and rear door (or door and rear wing) is the central rack. It's written in letters. "B" It is a key safety feature in side impact.
There are down the doors. threshold. These are reinforced elements connecting the front and rear parts of the body at the bottom. The sleeves are sleeved (on some SUVs) and welded. It is the rapids often suffer first from corrosion due to salt and dirt flying from under the wheels, so their condition should be paid special attention when buying used cars.
The body racks have their own numbering, which is important when discussing damages:
- ๐ ฐ๏ธ Stand A. - front inclined pillar, framing the windshield.
- ๐ ฑ๏ธ Stand B. Central rack between the front and rear doors (on 4-door cars).
- ๐จ๏ธ Stand C. (and D) - rear racks supporting the roof in the trunk area.
โ ๏ธ Warning: Never neglect the anticory of the rapids and arches. Restoring rotten rapids is a time-consuming process that requires welding and removal of the cabin.
Also to the side part are rear-view mirrors and moldings. Moldings are decorative or protective pads, often running along doors or around windows. They protect the coating from scratches and chips. Window openings are framed by seals, which over time can dry up and require replacement to maintain silence in the cabin.
Roof and top elements
The roof is the โceilingโ of the car, a metal sheet welded to the racks and frame of the wind window. There may be various elements on the roof. Wagons and hatchbacks are often found rail (or arcs) for the attachment of the trunk. Some models have a hatch that breaks the monolithicity of the roof, but increases comfort. Along the roof often run gutters, diverting rainwater from the glass.
A special place is occupied by spoilers and wings. While many people confuse these concepts, there is a difference. Spoiler. To spoil - spoil, interfere) changes the air flow, reducing lift or turbulence. The wing creates downforce, pressing the rear axle to the road. On civilian cars, it is most often an element of aesthetics and easy aerodynamic correction.
What is the difference between a skylight and a panoramic roof?
A hatch is an opening segment in the roof, usually sliding or rising. A panoramic roof is a large glazing that occupies a significant part of the roof, often not opening entirely, but allowing a lot of light to pass through.
An antenna is also mounted on the roof to receive radio signals and GPS/GLONASS. In modern cars, antennas are often embedded in glass or a โshark finโ, which improves aerodynamics and appearance. The integrity of the roof is critically important: when a car is turned upside down, it is the racks and roof that prevent the cabin from being a โhouse of cardsโ.
Rear: trunk and lighting
Completes the body structure of the rear part. The terminology here depends on the type of body. The sedan has a trunk lid, the hatchback and wagon have a fifth door (or just a trunk door). Under the trunk lid is a niche that houses a spare wheel (or remix), a battery (on some models) and a fuel tank that is usually protected by a metal screen.
The most important safety and dimensions are the taillights. They combine signals of braking, turning, reversing and dimensions. Between the lights is often located decorative overlay or numbered niche. The rear bumper, like the front, can be equipped with parking sensors - sensors that help with parking.
The following table helps to classify the main body types by their rear end:
| Body type | Characteristics of the rear | Example |
|---|---|---|
| sedan | Separate trunk, lid does not rise with glass | Toyota Camry |
| hatchback | The door rises with the rear window. | Volkswagen Golf |
| Universal | Elongated interior, door rises with glass | Lada Vesta SW |
| liftback | Visually similar to a sedan, but the lid opens with glass | Skoda Octavia |
The rear panel (rear) is the vertical part of the body under the rear window (hatchbacks) or behind the back of the rear seat (sedans). It is attached to the taillights and the trunk lock. When hitting from behind, it is often this element and spars that go deep under the trunk floor.
โ๏ธ Checking the condition of the body when buying
Hidden elements and the bottom of the car
We will conclude our tour of the anatomy of the car by examining what is hidden from view. The bottom is the bottom of the body. It experiences maximum loads from the road surface, reagents and moisture. To protect the bottom of the plant apply special mastics, and on top often install plastic crankcase and aerodynamic screens.
There are fuel and brake lines along the bottom. It is important to know that any body repair work from below requires caution to avoid damaging these communications. Also, the design of the bottom integrated points for installing the jack - reinforced places designed to lift the car. To lift the car for random places of the bottom is absolutely impossible - the metal will remember, and you can damage the internal elements.
The internal arches of the wheels are another risk area. They are in constant contact with sand and stones. Often this is where corrosion begins, which then passes to the wings and sills. Modern cars have plastic arches (lockers) that protect metal, but moisture can also accumulate under them.
When washing a car, be sure to remove plastic lockers (slats) at least once a year to wash the dirt accumulated there - this will prolong the life of arches and sparrows.
It's worth mentioning. engine-splasher (casecase protection) that closes the engine compartment from below. They are metal (strong but heavy) and plastic/composite (light, noise-quenching, but less durable). Their availability depends on the configuration of the car.
โ ๏ธ Warning: When installing a non-standard crankcase protection, make sure it has the right openings for engine ventilation and emergency lowering of the motor on impact. A deaf metal plate can be dangerous.
Frequently Asked Questions (FAQ)
What is a โglassโ in the back of a car?
Glass. The upper part of the front or back arch is inserted into the upper turn of the shock absorber. This is the place where the shock absorber is attached to the body. During repair, glasses are paid special attention, since their deformation leads to a violation of the collapse-descendence of the wheels.
What is the difference between a spanger and a threshold?
longeron It is an internal power element, a beam running along the bottom (often inside or under the threshold). Threshold It is the external element that we see from the side, covering the lower part of the doorway. The threshold is welded to the spangeron and the racks.
Why is it important to know the names of the body parts?
This is necessary for competent ordering of spare parts (so as not to buy a hood instead of a wing), an accurate description of damages in the insurance policy and understanding the severity of an accident when buying a used car.
What is a "television" of a car?
Television (or front crossbar) is a metal frame in the front of the body, to which radiators, a fan, a hood lock and sometimes the lower bumper mounts are attached. It connects the front sparrows and cups of shock absorbers.
Knowing the anatomy of the body is not just a theory, but a practical skill that will help you save money on repairs and protect yourself while operating a car.
