Why is the steering wheel of a small car heavy?

[LeAmelia]

The reasons for a heavy steering wheel in a small car are: 1. Insufficient power steering fluid; 2. Dirty power steering fluid; 3. Malfunction of the power steering booster; 4. Low tire pressure; 5. Toe-in malfunction; 6. Fault in the steering gear or power steering pump; 7. Overly tight bearing fit. The function of the steering wheel is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Precautions for steering wheel operation include: 1. When turning the steering wheel back, do it quickly and accurately return to position; 2. Do not apply excessive force when turning the steering wheel; 3. When driving in hazardous mountainous areas or on poor road surfaces, hold the steering wheel with both hands to prevent accidents; 4. Avoid turning the steering wheel when the vehicle is stationary.
