There is a reason for both this sound and that loud noise that sometimes emerges when shifting into reverse gear. Basically everything at the moment gear box because of gears.

forward gears have a different structure We see that the reverse gear does not have the same characteristics, although we see that it works silently and more comfortably thanks to the

Why is there a strange sound when reversing in the car?

When we look at a vehicle’s transmission system, we see that the forward gears and the reverse gears have different shapes. Gears in forward gear”helical gearThey have a curved structure called “.

This incline allows more gears to be engaged when shifting gears. Thanks in part to the slope a smoother transition takes place and makes work much quieter.

In reverse gears, there are spur gears instead of bevel gears. gears, Instead of slipping like gears when engaged, they collide directly. This is the reason for that noise that occurs when shifting gears.

Moreover, because it is not in a spiral structure like a spiral spur gears have more backlash. This gap can also appear as the reason for the buzzing sound that increases as the vehicle accelerates.

Why is the gear transmission not used in reverse gear?

If bevel gears make less noise and grip much better because of their curved structure, then why? other way around You can say that these gears are not used. The biggest disadvantage of helical gears is that it is difficult to switch between them.

For this reason, forward gears are always stays connected and shifting is made possible by a piece called synchromesh. For this reason spur gears are used instead of bevel gears in reverse gears.
