Effective torque

From Wikipedia, the free encyclopedia

Effective Torque is often referred to as wheel torque or torque to the wheels is primarily associated with automotive tuning. Torque can be measured using a dynamometer. Common units used in automotive applications can include ft·lbf and N·m. For more on units see: Foot-pound force.[1]

The formula for effective torque to the wheels is:[2]

Tw = Te * Ntf * ηtf

Ntf = Nt * Nf

ηtf = ηt * ηf

... where Tw is wheel torque, Te is engine torque, N is the gear ratio, η is the efficiency, and the subscripts t and f are for the gearbox and differential, respectively.[citation needed] Effective torque will often be 5-15% lower than the shaft or crank ratings of an engine due to a loss through the drivetrain.
