Introduction: Why does the name of a truck steering wheel raise so many questions?
Even experienced drivers sometimes get confused when it comes to truck steering. Someone calls him steering wheel, someone - helm, and in technical documentation the term is often found steering wheel. The discrepancy in names does not arise by chance: historically, different areas - from everyday communication to the professional jargon of mechanics - use their own variants.
For a new driver who is just getting into truck transport, this confusion can be a source of misunderstanding. For example, in the operating instructions Scania R470 you will come across the term steering wheel, and a colleague in the workshop will say: “Twist it steering wheel to the left." Meanwhile, the correct name not only simplifies communication, but also helps when ordering spare parts or discussing faults with a technician. In this article, we’ll look at what the “twist” on a truck’s steering wheel is officially called, where alternative names come from, and why it’s important for safety.
Spoiler: traffic rules and technical regulations use a strict term, but other options have taken root in drivers’ practice. Let's also find out why Kamaz-6520 the steering wheel may be called differently than on Volvo FH16 - and this is not a mistake!
Official name: what traffic regulations and technical standards say
According to GOST R 52302-2004 (national standard of the Russian Federation regulating terminology for motor vehicles), the correct name for the steering wheel is steering wheel. This term is used:
- 📄 In vehicle passports (PTS) and registration certificates;
- 🔧 In the repair and maintenance instructions;
- 📜 In regulations, including Traffic Rules (TRAF).
For example, clause 2.3.1 of the traffic rules states: “The driver is obliged to check before departure... serviceability steering (including steering wheel)". The same can be found in European standards, such as UNECE Regulation No. 79where the term is used steering wheel (literally “steering wheel”).
However, this term is almost never used colloquially. Why? The point is that steering wheel - This is a technically accurate, but too formal option. It is convenient for documents, but not for everyday communication. Moreover, in English wheel is associated with the wheel of a car, not the steering wheel, which adds to the confusion.
“Baranka”: where did this name come from and why did it stick?
Word steering wheel is a purely colloquial term that has firmly entered the driver’s lexicon. Its origin has two versions:
- Historical: in the first cars, the steering wheel actually resembled a steering wheel in shape (a ring with thickenings for gripping). For example, on Ford Model T (1908) the steering wheel was thin and round, like a donut.
- Slang: in Soviet times, abbreviated or ironic names of parts took root among truckers and mechanics. “steering wheel” sounds simpler and shorter than “steering wheel”, and is also associated with food - which is important for drivers who spend a lot of time on the road.
Today steering wheel They call the steering wheel not only of trucks, but also of cars, although in the latter this name is less common. Interestingly, in some regions of Russia the word may have a negative connotation - for example, the phrase “hold the steering wheel" is sometimes perceived as "drive carelessly" However, among professionals (especially in MAZ, Kamaz or Ural) is a neutral and generally accepted term.
If you are communicating with a mechanic from Western Europe, it is better to use the term steering wheel - word steering wheel (baranka) they just won't understand.
"Rudder": marine terminology in trucks
Term helm came to the automotive field from maritime affairs, where the steering wheel on ships is called that. In trucks this name is used less frequently, but still occurs, especially:
- 🚛 For drivers truck tractors (for example, Mercedes-Benz Actros or Scania S-series), where the steering wheel in size and shape really resembles a ship's wheel;
- 🛠️ In workshops specializing in the repair of steering systems of foreign trucks (English terminology is often used there);
- 📚 In textbooks for driving schools, where the emphasis is on universal terms.
It is important to understand that helm is not a completely correct term for a truck, but it caught on thanks to the analogy with large equipment. For example, on BelAZ-75710 (quarry dump truck) the steering wheel is really massive and looks like a ship's, so drivers and mechanics can use this word.
⚠️ Attention: In technical documentation Volvo or DAF there is no term “steering wheel” - it is used only steering wheel. If you order spare parts, be sure to name the part correctly, otherwise you may have trouble finding it.
Other names: “krutilka”, “ram” and regional variants
In addition to the basic terms, in different regions and professional circles you can hear other names for the steering wheel of a truck. Here are the most common:
| Title | Where is it used? | Examples |
|---|---|---|
| Spinner | Colloquial speech, often among beginners | "Twist it twister to the right" |
| Ram | A truncated version of the “steering wheel”, found in Siberia and the Urals | "Hold ram stronger on turns" |
| Steering wheel | Universal term, but less commonly used in trucks | "On ZIL-130 steering wheel heavier than MAN» |
| Ring | Mechanic jargon when talking about replacing a steering wheel rim | "Put in a new one ring on steering wheel» |
Interestingly, in some CIS countries (for example, in Kazakhstan) you can hear the word dongelek (translated as “circle”), and in Ukraine - kermo (from the Ukrainian “kermo” - steering wheel). These options are not related to technical terminology, but reflect local features of speech.
Why do trucks have larger steering wheels than cars?
The size of the steering wheel in trucks is determined by two factors:
1. Turning force: the larger the diameter, the easier it is to turn the wheels (the lever is longer).
2. Ergonomics: The truck driver needs fewer hand movements to maneuver, which reduces fatigue on long routes.
For example, steering wheel diameter Kamaz-5490 - about 50 cm, and Toyota Corolla — 38 cm.
Why the correct name is important for safety and repair
It would seem, what does it matter what the steering wheel is called? However, incorrect terminology can lead to serious problems:
- Errors when ordering spare parts: if you tell the seller “I need steering wheel on MAN TGS", he may not understand what you need steering wheel (and this is the official name in catalogs). As a result, you will receive the wrong part.
- Miscommunication in emergency situations: for example, when teaching a beginner, the instructor says “turn helm", but the student does not react because he is used to the word "steering wheel".
- Problems with insurance or traffic police: the term is used in protocols and acts steering wheel. If you write “the steering wheel is damaged,” this may be a reason for refusal of payment.
Critical detail: In trucks, the steering wheel is often equipped with additional controls (cruise control buttons, light switches, communication keys). If you call it incorrectly, the technician may not understand which part you are talking about - for example, the wheel itself or the steering column switches.

Remove the negative terminal of the battery (to avoid short circuit)
Check airbag compatibility (if equipped)
Use a torque wrench to tighten the fasteners-->
What is the name of the steering wheel in different brands of trucks: features of terminology
Truck manufacturers also contribute to the naming confusion. Here's how popular brands fare:
- 🚚 Kamaz and Ural: used in documentation steering wheel, but drivers and mechanics almost always say steering wheel.
- 🇸🇪 Scania and Volvo: in the manuals -
steering wheel, in Russian-speaking circles - “rudder” or “steering wheel” (due to the maritime association). - 🇩🇪 Mercedes-Benz and MAN: officially - Lenkrad (steering wheel), in Russia it is often translated as “rudder”.
- 🇺🇸 Freightliner and Peterbilt: only
steering wheel, other options are not used.
Interesting fact: on BelAZ (Belarusian mining dump trucks) the steering wheel is called helm even in official instructions. This is due to the fact that operating such equipment really resembles steering a ship - due to the size and features of the steering mechanism.
⚠️ Attention: If you are purchasing a steering wheel for DAF XF or Renault Magnum, pay attention to manufacturer's article number. For example, at DAF the catalog may indicateSteering wheel, 500mm, leather- here 500 mm is the diameter, andleather— rim material (leather).
In trucks with power steering (power steering) or electric power steering (EPS), replacing the steering wheel may require reflashing the control unit. Always check with your dealer!
FAQ: answers to frequently asked questions about truck steering wheels
Is it possible to install a steering wheel from a car onto a truck?
No, this is not possible for several reasons:
- 🔧 Fastening: trucks have a different seat standard (usually 6 bolts, not 4, as in cars);
- 📏 Size: the steering wheel diameter of a truck is larger (45–52 cm versus 36–40 cm for passenger cars);
- ⚡ Electronics: Modern trucks have sensors and control buttons built into the steering wheel that are not compatible with passenger car systems.
The exception is some pickups (for example, Ford F-150), where the steering wheel can be adapted, but this requires improvements.
Why do older trucks have heavier steering than new ones?
This is due to the lack of power steering. In models before the 1990s (for example, ZIL-130, GAZ-53) the steering was purely mechanical - the force was transmitted directly through the steering mechanism and rods. Modern trucks use:
- 💧 Hydraulic booster (power steering) - on most Kamaz and MAZ;
- ⚡ Electric booster (EUR) - on Scania, Volvo new generations.
In addition, older trucks often used steering wheels with thickened rim, which also increased the load on the hands.
What happens if the steering wheel breaks while driving?
It depends on the type of failure:
- 🔩 Crack in the rim: the steering wheel can turn in your hands, but control will remain;
- 🔧 Broken fastening: the steering wheel is completely disconnected from the column - control is lost;
- ⚡ Electronics failure (on steering wheels with buttons): the steering column switches may not work, but the control itself will remain.
What to do: If the steering wheel begins to play or squeak, stop immediately and check the fastenings. Driving with a faulty steering wheel is dangerous - this is equivalent to driving a faulty vehicle (fine under Article 12.5 of the Code of Administrative Offenses of the Russian Federation - 500 rubles).
What is the correct name for the steering wheel in a conversation with a traffic police inspector?
In official communication (when registering an accident, passing a technical inspection), use the term steering wheel. This corresponds to:
- 📜 Traffic rules (clause 2.3.1);
- 📄 Technical regulations of the Customs Union (TR TS 018/2011);
- 🔧 Inspection protocols (for example, when checking steering wheel play).
If the inspector himself uses the word “steering wheel”, you can continue the conversation, but the documents must indicate steering wheel.
Can I change the steering wheel on my truck myself?
Theoretically yes, but there are nuances:
- ✅ Easy replacement (without airbag): you will need a 24–27 wrench and a torque wrench for tightening;
- ⚠️ With airbag: you need to disconnect the battery and wait 10–15 minutes (so that the capacitors are discharged), otherwise the squib will work;
- ❌ On trucks with EUR: It may be necessary to reset errors via a diagnostic scanner (for example, Launch X431).
If you are not sure, it is better to contact the service - an installation error can lead to uneven tire wear or loss of control.
