But it can also reduce your top speed and fuel economy. The gear ratio i g of a gear train is the ratio of the angular velocity of the input gear N e engine side to the angular velocity of the output gear N g propeller shaft and differential side also known as the speed ratio of the gear train. Its not 5th gear its not 6th gear.

The final ratio is usually considered seperate from the main transmission kind of like the front sprocket on a bicycle. Meaning of final drive. What does FDR mean.

I read one definition saying its the turns of the engine to the turns of the wheel but that only proves to me that for instance if the final drive ratio was 101 with a car that redlines at 5000rpm then the wheels can turn at a max of 500 rpm thereby limiting top speed.

Tip Check the loading on extruder motors and modify the gear ratios to optimise motor energy use. Information and translations of final drive in the most comprehensive dictionary definitions resource on the web. If you increase the final drive ratio each gear will have greater wheel torque while sacrificing top speed.

More torque at the wheels but a lower top speed. However if you are pulling heavy trailers or want to pull large loads you may want the highest final drive ratio possible. A cars gearing is all about compromise.

When a car makes a turn the wheels must spin at different speeds. A gear train is a mechanical system formed by mounting gears on a frame so that the teeth of the gears engage. Ive seen such numbers as 3731 or 3421 but what does it all mean.

1 means that the driveshaft will turn 355 times every time the wheel turns once. I like to remember the term 411 posi commonly assosciated with built muscle cars as it refers to the lower ratio higher leverage positraction extremely limited slip differential. An axle ratio like 355.
