Axle Torque

IMPERIAL

The torque available at the driving axle is the hydraulic motor torque multiplied by gear reduction through the transmission and axle.

Ta = T x Rta x Ra

Ta = Axle torque (lb in)

Ra = Axle gear reduction

Rta = Gear reduction through auxiliary transmission if used

T= Motor torque (lb in)

Example:

What is the rear axle torque in high gear on a vehicle having 1000 lb. in motor torque, an auxiliary ratio of 4:1, and an axle ratio of 20:1?

Ta = 1000 x 4 x 20 = 80,000 lb in.
