I saw a brand new ’69 plate car reversing today and it still made that noise so it can’t be attributed to an old gearbox
In: Engineering
Most cogs in cars’ gearboxes mesh together with >>> patterns (helical cut or constant mesh) as it is quieter than straight cut gears III. Actually Citroen’s logo looks this way >> as this type of gear was invented by someone at the company. Reverse gears however are usually straight-cut as they take up less space and are much more simple gears. Reverse gears aren’t used as much as the rest of the gears so it is a good compromise.
Straight cut gears are strong however and in applications where being quiet is not so important (heavy machinery and rally cars) you hear whiny gears.
