Every time we reverse, regardless of manual or automatic transmission, we hear this voice.

Actually this situation reverse gears related to. Let’s explore the topic a little further.

Most modern vehicles use helical gears for forward gearing.

The name spiral gears comes from the fact that the teeth are spiral-shaped (i.e. at an angle). Thanks to this slanted structure, the gears mesh slowly, which ensures that the force at the gear inputs is distributed more evenly. The functioning is therefore more silent and smooth It is possible.

Straight gears are usually used for reverse gear.

Because the surfaces of spur gears are parallel, the gears fit together precisely and suddenly. This situation is more likely because of the full contact of the gear surfaces. a loud noise and vibrations causes the level.

In summary, the teeth hitting each other hard in spur gears makes a loud noise that can be heard both inside and outside the vehicle. is the main source of sound.

So shouldn’t helical gears be used in reverse gear?

This is where it comes into play cost it comes in. Since reverse gear is generally the least used gear in a vehicle’s transmission, spur gears are preferred to reduce costs. Because gears are both more expensive to produce and take up more space in the car.

Before concluding our content: this noise that occurs when we engage reverse gear is not an indication of a problem, but if it is extremely loud and deviates from normal, it may be related to the transmission. It could be a sign of a problem Let us also remember.
