When a driver or motorist looks at the car, he rarely thinks about how technically competently named certain elements of the body. However, when buying spare parts, getting insurance after an accident or talking to a master in the service, accurate knowledge of the terminology becomes critical. Top of the car. It is not just a “cover”, but a complex engineering structure consisting of many elements, each of which has its own unique name.
In everyday life, this area is often called simply a roof, but for professionals it is only one of the components. Understanding that, What is the name of the top of the car?This will help you avoid misunderstandings when ordering glass, repairing after hail, or installing additional equipment such as a trunk or hatch. In this article, we will examine in detail the anatomy of the top of the car.
Knowing the right terms is not just a tribute to erudition, but a practical necessity for any owner. vehicle. This allows you to quickly find information in manuals and more accurately describe the problems to specialists. Let's dive into the device of the car "top".
Main element: Roof and its varieties
The central element of the upper body is roof. This is a metal panel that connects the side racks and forms the ceiling of the cabin. It is the roof that ensures the rigidity of the body to twist and protects passengers in the event of a car rollover. In modern cars, the roof design can differ significantly depending on the type of body and purpose of the machine.
The most common option is an all-metal roof, which is welded to the frame of the body. But there are other solutions. For example, in convertibles, the roof can be foldable, made of fabric or rigid segments. In some sports models, you can find a roof type. Targawhere only the central part above the driver's head is removed, and the rear part remains.
When buying a car with a panoramic roof, be sure to check the condition of seals and opening mechanisms, as their repair costs much more than maintenance of a conventional metal roof.
Particular attention should be paid to panoramic roofs, which are becoming the standard for the premium segment. They are a large glazed space, often occupying almost the entire top area. While this adds aesthetics and light to the car, this design requires more care and regular leakproofness checks.
The roof of the car is not just protection from precipitation, but the most important power element that ensures the safety of passengers during a coup and the overall rigidity of the body.
Vertical support: Body struts
The roof cannot exist without the support. Vertical or inclined elements supporting the top of the machine and framing window openings are called strutting. Their numbering is done from the front to the back, and knowledge of these names is necessary when discussing damage, for example, after a side impact.
The first pair of pillars located on the sides of the windshield is called A-pillars.. They are the most loaded in terms of safety, as they must withstand the weight of the roof during a flip and extinguish the energy of the impact during a frontal collision. Often it is in the A-racks that airbags and wiring elements are hidden.
- 🚗 A-stand: Front sloping rack separating the windshield and side glass.
- 🚙 B-stand: Central vertical rack between the front and rear doors (on sedans and hatchbacks).
- 🚕 C-stand: The back pillar forming the rear window opening.
- 🚐 D-stand: Additional rear rack, characteristic of station wagons, minivans and SUVs.
On the two-door coupe often does not have a B-rack in its usual form, or it is shifted far back to facilitate landing. The lack of a central support requires reinforcement of the sills and the roof itself, which is an engineering trade-off between convenience and rigidity. When choosing a car with long openings without a central support, this nuance should be taken into account.
Glazing: Windscreen and side windows
The top of the car is impossible to imagine without glass. Windshield The windshield is the largest glass element installed between the A-racks. It is made of a multilayer triplex, which does not fall into sharp fragments when hit, but is covered with a network of cracks, remaining in the frame.
Side glass, often called window-piece If they are open, or just open, they are placed in the slabs. In modern cars, side windows are often made of tempered glass, which, when destroyed, crumbles into small safe granules. Replacing these elements requires high qualification, since a leakage violation will lead to noise and leaks in the cabin.
⚠️ Note: When replacing the windshield, it is critical to use a quality sealant and let it dry completely before use. Getting on the road ahead of time can lead to displacement of the glass and loss of tightness, which is life-threatening.
The back glass is also part of the upper structure. In hatchbacks and station wagons, it is often part of the fifth door.
Why doesn't the windshield crack from the stones right away?
Modern windshields consist of two layers of glass and a polymer film between them. This film (polyvinylbutyral) holds the fragments together and quenches the vibration, preventing the crack from spreading instantly across the surface.
Water gutters and gutters: Protection from moisture
One of the most vulnerable areas of the upper part of the machine are the junction of the roof and glass or roof and doors. For the removal of rainwater and melted snow in the design provided drainage. These are special channels or gutters that direct the flow of water down, bypassing the interior of the car.
In older models of cars, gutters were often presented as open gutters running along the roof on the sides. They often accumulated dirt and leaves, causing corrosion. Modern cars lack such exposed elements; water flows down hidden channels inside racks or along special profiles hidden under seals.
| Element | Location. | Function | Risk of clogging |
|---|---|---|---|
| drainage | Along the roof (old cars) | Water collection and withdrawal | Tall (leaves, dirt) |
| The hidden channel | Inside the A-pillar | Water drainage from the windshield | Medium (small garbage) |
| drainage | Down the rack or threshold | Water out of the system | Tall (ice, dirt) |
| Glass sealer | Perimeter of glass | Sealing and flow direction | Low (tyre wear) |
Regular cleaning of areas around the glass and checking drainage holes is the key to a dry cabin. If you notice water on the floor after rain, first check the drainage system of the upper body. A clogged drainage can cause water to go inward, over the edge, damaging electronic blocks that are often located under mats.
Additional elements: Hatches, spoilers and antennas
The top of the car is often equipped with additional devices that improve functionality or aerodynamics. Luke. The opening segment in the roof can be mechanical or electrical. It consists of a glass or metal panel, lifting mechanism and sealing system.
The back of the roof is often installed. spoiler. Unlike the wing, which creates downforce, the spoiler primarily “breaks” the air flow, reducing the lift of the body and reducing the contamination of the rear window. On many modern models, spoilers are an integral part of the design and even hide the stop signals.
- 📡 Antenna: It can be a pin (wrought into the roof) or built into glass (spray).
- 🦈 Fin: A modern type of antenna that combines GPS, GSM and radio in one streamlined enclosure.
- 🎒 Railings: Longitudinal arcs on the roof, which serve as the basis for fastening trunks and bicycles.
☑️ Checking the condition of the top of the car
The upper elements also include railing and crossbars. They allow you to turn a smooth roof into a useful cargo platform. When installing them, it is important to observe the puffing moment and use adapters that are suitable for your roof type so as not to damage the metal or geometry of the openings.
Typical problems and care of the upper part
The upper part of the machine is constantly exposed to aggressive environmental influences: ultraviolet, hail, bird droppings, reagents and temperature changes. The most common problem is corrosionThis often starts with microscopic chips of paint on the roof or at the junction of elements.
Owners of cars with panoramic roofs or hatches should especially carefully monitor the state of the drainage system. The leaves and dirt that get there turn into a gruel, which blocks the outflow of water. In winter, this water freezes, expands and can deform the hatch mechanism or squeeze out seals, which will lead to leakage.
⚠️ Warning: Never try to open a frozen hatch or a closed door by force. This can lead to a breakdown of the drive mechanism or rupture of the sealing gum, which will cause expensive repairs.
To protect the paint coating of the roof, it is recommended to use ceramic coatings or high-quality polishing. The roof is the flattest and most visible part of the body, and any defects (holograms, scratches) are visible on it best. Regular washing, especially after winter reagents, will prolong the life of the metal.
Why does rust appear faster on the roof?
The roof of a car often gets microscopic damage from hail and falling branches that are difficult to spot right away. Moisture gets into these places, and due to the horizontal position, the water stagnates longer than on vertical surfaces, triggering the process of corrosion under the paint layer.
Another problem is the fading of paint. Since the roof takes on the maximum solar radiation, it is the first to begin to lose color if the car is stored in the open air. Using covers or garage storage significantly slows down this process.
Regular cleaning of drainage channels and monitoring of seal integrity is the most effective way to avoid expensive repairs of the cabin and electricians from moisture.
What is the name of the roof on the back?
The sloped back of the roof connecting the main top to the trunk or fifth door is called the post-scatter Or just a roof ray. In coupe and fastbacks, this line is a key design element that defines the silhouette of the car. In the technical documentation, this transition can also be called the “back panel of the roof”.
What to do if you rust the roof from the inside?
If you find paint bloating on the roof, it’s a sign of corrosion from the inside. It is necessary to clean the damaged area to metal, treat with a rust converter, prime and paint. In advanced cases, it may be necessary to digest a part of the sheet or install a lapel, which is a complex bodywork.
Can I wash a car with a damaged hatch seal?
Washing a car with a damaged sealer is possible, but it is highly recommended not to use high-pressure washers, directing the jet directly to the hatch. Pressure water is guaranteed to penetrate the cabin, damaging the ceiling lining and electronics. It is better to use a manual wash and temporarily seal the defect with water resistant tape before replacing the seal.
What is the name of the metal frame around the glass?
The metal or plastic frame that frames the glass and hides the edges of the sticker is called molding Or the edge. Modern cars often use black ceramic printing on the glass itself (fritta), which mimics the frame and protects the sealant from ultraviolet radiation, so individual metal frames may be absent.
Why do you need a notch on the A-pillar inside the cabin?
Notches or roughness on the inside of the A-rack (where the skin is attached) are needed for better adhesion of the glue when sticking airbags or for fixing plastic clips of the skin. They can also serve as guides for the correct positioning of safety elements when assembled in the factory.
