Нужно ли выжимать сцепление при торможении? В каких случаях мы работаем сцеплением?

Summary

In this video, an experienced driving instructor explains the correct usage of the clutch during various driving scenarios. He outlines when to engage and disengage the clutch, focusing on crucial moments such as engine startup, shifting gears, slowing down, and coming to a complete stop. He emphasizes the importance of understanding these actions rather than memorizing them and highlights the dangers of developing incorrect habits, especially in emergency situations. Through practical examples, the instructor helps viewers understand the correct timing and technique for using the clutch in different conditions, including snowy or icy roads.

Takeaways

• 😀 **Clutch Use at Engine Start**: Always press the clutch when starting the engine to prevent the car from moving unexpectedly, especially in cold weather when oil can thicken and cause resistance.
• 😀 **Pressing the Clutch for Gear Shifting**: You must press the clutch to disengage the engine from the transmission before shifting gears. This ensures smooth transitions between gears.
• 😀 **Clutch and Low-Speed Braking**: When braking at low speeds, pressing the clutch prevents the engine from stalling, especially as the engine’s RPM drops.
• 😀 **Clutch at Full Stop**: Pressing the clutch is necessary when coming to a full stop to prevent the engine from stalling. It’s crucial when your speed is low or when you anticipate a complete stop.
• 😀 **Avoid Pressing the Clutch at High Speeds**: When driving at higher speeds, avoid pressing the clutch unless you’re shifting gears or preparing to stop. This maintains better control of the car.
• 😀 **Clutch and Skidding Risks**: Avoid pressing the clutch on slippery roads (e.g., snow, ice) as it disconnects the engine from the wheels, reducing engine braking and making the car less stable.
• 😀 **Emergency Braking Habit**: In emergencies, prioritize pressing the brake first, not the clutch. Pressing the clutch first can waste valuable time, as every second counts when avoiding a collision.
• 😀 **New Driver Mistake**: Many beginners develop the habit of pressing the clutch before braking, which can reduce reaction time and make emergency braking less effective.
• 😀 **Clutch and Engine Load**: Pressing the clutch in cold weather helps reduce strain on the engine and transmission by disconnecting the engine from the drivetrain, especially in extremely low temperatures.
• 😀 **Learn Proper Clutch Habits Early**: Developing good clutch habits early (e.g., when to press or release) will help avoid long-term mistakes and lead to smoother, safer driving, especially in urban traffic.

Q & A

Why is it important to press the clutch when starting the engine in cold weather?

Pressing the clutch helps to reduce the strain on the engine during startup, especially in cold weather. When temperatures drop below -20 or -30°C, the oil in the engine and gearbox becomes thick, similar to cream. By pressing the clutch, you disconnect the engine from the gearbox, which prevents unnecessary strain on the gearbox components and makes it easier for the engine to start.

What is the second reason to press the clutch when starting the engine?

The second reason is safety. If you don't press the clutch when starting the engine and the car is in first gear, the vehicle might unexpectedly move forward, especially if the handbrake is not fully engaged. Pressing the clutch ensures the vehicle stays stationary upon starting.

When do we need to press the clutch in normal driving conditions?

You need to press the clutch when you want to change gears. When the clutch is not pressed, the engine is mechanically connected to the gearbox, which means that the engine’s rotational force is transmitted to the wheels. By pressing the clutch, you disengage this connection, allowing you to safely switch gears.

Why should the clutch be pressed during full stops?

When slowing down and coming to a complete stop, pressing the clutch is necessary to prevent the engine from stalling. As the car slows down, the engine's RPM decreases. Without pressing the clutch, the engine may reach too low RPM, causing it to shake and potentially stall. By pressing the clutch, you disconnect the engine from the wheels, preventing stalling.

Why should you press the clutch when driving slowly, such as in traffic or while crawling?

When moving at very low speeds, such as in traffic, you should press the clutch to avoid stalling the engine. At low speeds, the engine’s RPM can drop to a point where it may stall if it’s still connected to the wheels. Pressing the clutch helps maintain engine functionality without stalling.

When is it not necessary to press the clutch while braking?

When driving at higher speeds (e.g., 30-40 km/h or more) and you only need to reduce speed, you do not need to press the clutch. Pressing the clutch is unnecessary because the engine is still running at higher RPMs, and the car can slow down using engine braking without disconnecting the clutch.

What are the dangers of pressing the clutch while driving on slippery or unstable surfaces?

Pressing the clutch on slippery or unstable surfaces (such as snow or ice) reduces engine braking, which can make the car less stable. When the clutch is pressed, the car loses traction because the engine is no longer helping to slow down the wheels. This can be dangerous, especially on downhill slopes or during sharp turns.

How does pressing the clutch affect the car during emergency situations?

In an emergency situation, pressing the clutch before applying the brake can delay your reaction time. If you have developed a habit of pressing the clutch first, it may take a second longer to start braking, which could be critical in avoiding an accident. The correct sequence is to brake first and only press the clutch if necessary.

What is the main habit many novice drivers develop regarding the clutch and braking?

Many novice drivers develop the habit of pressing the clutch before braking, especially when they first learn on a practice track. This reflex is formed because they often use the clutch and brake together at low speeds. However, this habit is not ideal for regular driving, and drivers should learn to brake first, then press the clutch when needed.

When should the clutch be pressed during a smooth stop on the road?

The clutch should be pressed as you approach a complete stop, particularly when the car is moving at low speeds, and the engine's RPM is dropping. This ensures that the engine doesn’t stall. At higher speeds, the clutch is not needed for braking, and you can slow down without disengaging the clutch.
