The steering ratio is the ratio of the number of degrees of turn of the steering wheel to the number of degrees the wheel(s) turn as a result. In motorcycles, delta tricycles and bicycles, the steering ratio is always 1:1, because the steering wheel is fixed to the front wheel. A steering ratio of x:y means that a turn of the steering wheel x ...
Simplified diagram of gear inches: As the rear sprocket is halved in size, the distance traveled by the rear wheel doubles, at half the torque. Gear inches is one way of measuring the gear ratio(s) of a bicycle, so that different gears and different bicycles can be compared in a consistent manner. Gear inches is an imperial measure ...
Spur-gear differential. A spur-gear differential has equal-sized spur gears at each end, each of which is connected to an output shaft. [8] The input torque (i.e. from the engine or transmission) is applied to the differential via the rotating carrier. [8] Pinion pairs are located within the carrier and rotate freely on pins supported by the ...
With the early development of cars and the almost universal rear-wheel drive layout, the final drive (i.e. rear axle) ratio for fast cars was chosen to give the ratio for maximum speed. The gearbox was designed so that, for efficiency, the fastest ratio would be a "direct-drive" or "straight-through" 1:1 ratio, avoiding frictional losses in the ...
The gear range is difference between the highest and lowest gear ratios and may be expressed as a percentage (e.g., 500%) or as a ratio (e.g., 5:1). Heel [ edit ]
Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio. For example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-gear sets vary from 10:1 to 500:1. [45] A disadvantage is the potential for considerable sliding action, leading to low efficiency. [46]

While the 9.5-inch rear end exhibits its own durability, it is generally considered less favorable for high-torque applications. The 9.5-inch C-clip rear differential was featured in both the Suburban and pickups, available in 6- or 8-lug variations, employing 33-spline axles. This differential remained in production through 2009 and even found ...
