Effective torque (often referred to as wheel torque or torque to the wheels) is a concept primarily associated with automotive tuning. Torque can be measured using a dynamometer. Common units used in automotive applications can include foot-pounds and Newton·meters. [1] The formula for effective torque to the wheels is: [2] Tw = Te * N tf * η ...
This broad sense includes wheel bearing resistance, the energy dissipated by vibration and oscillation of both the roadbed and the vehicle, and sliding of the wheel on the roadbed surface (pavement or a rail). But there is an even broader sense that would include energy wasted by wheel slippage due to the torque applied from the engine. This ...
Torque when one end of a 1 m long moment arm is acted upon by a force of 1 N. 10^2: 108 N⋅m to 149 N⋅m: 80 lb⋅ft to 110 lb⋅ft: Torque to which most lug nuts are tightened. [1] 10^2: 881 N⋅m: 650 lb⋅ft: Torque at the crankshaft of a Dodge Charger SRT HellCat. [2] 10^4 13,000 N⋅m Example 2 MW wind turbine, generator side. [3] 10^6 ...
Self aligning torque , slip angle , and camber angle are also shown. Self aligning torque ( SAT ), also known as aligning torque or aligning moment ( Mz , moment about the z direction ), is the torque that a tire creates as it rolls along, which tends to steer it, i.e. rotate it around its vertical axis.
Torque vectoring is a technology employed in automobile differentials that has the ability to vary the torque to each half-shaft with an electronic system; or in rail vehicles which achieve the same using individually motored wheels. In the case of automobiles, it is used to augment the stability or cornering ability of the vehicle.
Torque specifications vary by vehicle and wheel type. Both vehicle and wheel manufacturers provide recommended torque values which should be consulted when an installation is done. Failure to abide by the recommended torque value can result in damage to the wheel and brake rotor/drum. Additionally, under-tightened lug nuts may come loose with time.

When traveling in a straight line, where one wheel starts to slip (and spin faster than the wheel with traction), torque is reduced to the slipping wheel (Trq 2 ) and provided to the slower wheel (Trq 1 ). In the case when the vehicle is turning and neither wheel is slipping, the inside wheel will be turning slower than the outside wheel.
