4 Wheel Drive Gear Ratios

The tooth and wheel of the gear are basic workings parts of all types of gears.

4 wheel drive gear ratios.

Four wheel drive also called 4x4 four by four or 4wd refers to a two axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. How gears transmit power. Need of the final drive in an automobile. It s just backwards from the way we think if you have a 4 10 ratio and need better fuel mileage you would switch to a 3 42 or 3 73 gear ratio.

Increasing the tire diameter of a 4 4 effectively reduces the final drive ratio. This would mean that the input gear would have two revolutions. The gear ratio is the difference in the size of the pinion gear or input gear and the ring gear or output gear. The basic rear wheel drive turbo hydramatic spawned two front wheel drive variants the transverse turbo hydramatic 125 and the longitudinal turbo hydramatic 425.

1971 1994 3l80hd heavy duty version of th400. If your looking for more power or performance you would switch to a lower ratio. Vehicle manufacturers optimize the final drive ratio for overall vehicle performance and fuel economy. Hence this ratio is known as the final drive ratio.

The intention is to fit a tractor with 18 4 34 14 9 24 tires made by a certain manufacturer. The gears allow a torque bias ratio of 4 1 which means they can deliver four times as much power to the nonslipping axle than can be supported by the slipping axle. An example of this would be a gear ratio of 2 1. It may be full time or on demand and is typically linked via a transfer case providing an additional output drive shaft and in many instances additional gear ranges.

The transmission ratio of the gear pair for the front wheel drive axle is 1 425 gear pair i. In other words the gear ratio is the ratio between the number of teeth on two gears that are meshed together or two sprockets connected with a common roller chain or the circumferences of two pulleys connected with a drive belt. The transmission ratio of the front axle is 15 89. A third variant was the light duty rear wheel drive turbo hydramatic 180 used in many european models.

If you have a 3 42 rear end ratio and need more towing power you would switch to a 4 10 ratio. The differential gear pair is 53 9. A four wheel drive vehicle with torque supplied to both axles. This ratio cannot be changed on most front wheel drive vehicles but can be changed on many rear wheel drive vehicles.
