Yes, more than likely. What does this gain us when compared to a simple axle ratio swap? By the same physics, a given torque acting through an axle shaft can exert less road force using a larger diameter tire than a smaller diameter tire. If you have a limited slip or locker in the axle, you will need to jack up both tires on the axle as you cannot turn one tire without the other turning. Changing the final drive ratio requires a complete transmission teardown and rebuild. The preliminary spec sheet lists all Sasquatch final drive ratios as 4.7:1. Gearing & Torque The final drive ratio can vary depending on the car's curb weight and engine power output. For the case above, suppose we have stock 3.73:1 gearing in the axles. Thus, it provides the final speed reduction between 3:1 to 4:1. For instance, a 10-pound force exerted over a one foot distance is 10 lb-ft of torque. Convert P-Metric Tire to Inches. Your information will be collected and used in accordance with our  Privacy Policy. Thus, the first gear ratio is 7:21 and the second is 9:30. Of course the practical limitations of transmissions, gears, and final drive ratios that you can buy will be different, but the optimum ratios will guide your gear or transmission purchase decisions. Only two exceptions. The gear ratio formula turns out to be fairly simple. You basically count the number of teeth on the driven wheel and divide that by the number of teeth on the driver wheel, which is the one attached to the motor. It's a straightforward calculation, even when the gear system consists of several intermediate wheels called idlers. (a) One goal of the design is for the vehicle to reach a velocity of 30 m/s when the engine is turning 2500 RPM in 4th gear. Best bet is a junkyard transmission, if you can find one. Changing gears to a numerically higher ratio to compensate for the addition of larger tires should not harm engine or transmission life. Gear ratio is calculated by dividing the number of teeth on the ring gear by the number of teeth on the pinion gear. For every 3.23 revolutions of the smallest gear, the largest gear turns one revolution, or for every one revolution of the smallest gear, the largest gear turns 0.31 (1/3.23) revolution, a total reduction of about 1:3.23 (Gear Reduction Ratio (GRR) = 1/Gear Ratio (GR)). Engines will operate within their optimal powerband, providing smoother power delivery and avoiding excessively low end lugging that can wear bearings over extended time periods. 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.

Imagine lifting a bucket of water with your outstretched arm, with your hand one foot from your shoulder (small tire) versus two feet out from your shoulder (large tire). Primary and final drive are separate stages of power transmission. For our example, we’ll use a common 700R4. E.g., there are 8 teeth on the pinion and 30 teeth on the crown-wheel, as shown in the diagram. The drive axles impact a truck’s ability to pull heavy loads, the speeds it can travel at, the overall fuel usage, and conclusively the company’s bottom line. Obviously, for a rear-wheel drive Chevrolet, 4.11:1 gears were referring to the final drive ratio. High gear on a 700R4 is 0.70:1. The Final drive contains a pair of spiral-bevel gears comprising a pinion that connects to the propeller shaft and a ring gear that connects to a flange on the differential case.if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-carbiketech_com-medrectangle-3-0')}; The pinion gets the drive from the engine while the crown-wheel is attached to the wheels and rotates them. Given the final axle ratio of 3.08:1 in each car, the overall ratio drops to 2.156:1. Calculate a Rough Ratio. Part of your woes may simply be due to the gearing in your axles. Since both vehicle and wheel move together in a linear direction, the vehicle (linear) speed is equal to the linear speed of the wheel. As you know, this ratio is useful to accommodate repairing and maintenance. There is an issue with the manual diff in the DCT car where downshifts are no longer smooth and the auto mode doesn't work as well. As a general rule, when dealing with two gears, if the drive gear (the one directly receiving rotational force from the engine, motor, etc.) When the Bravo 1 came out in 1987, it was only available in a 1.36, for two years. For every one turn of the output shaft leading to a tire, the final drive ratio represents how many times the pinion gear on the motor shaft must turn. While this may work well for a stock truck with light loads, it's often not optimal for modified trucks or those towing heavy loads. The problem with that nomenclature is that it only takes on meaning relative to what size the stock sprockets are. The formula for calculating this is very straight forward, it is simply final drive ratio= primary x secondary x tertiary ratio A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. Manual transmissions can also benefit as clutches will last longer and provide better performance with big tires if the proper axle gear ratios are used.
