Axle Torque

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.

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 (N m)
Ra = Axle gear reduction
Rta = Gear reduction through auxiliary transmission if used
T = Motor torque (N m)

Example:
What is the rear axle torque in high gear on a vehicle having 100 N m motor torque, an auxiliary ratio of 5:1, and an axle ratio of 20:1.

Ta = 100 x 5 x 20 = 10,000 N m.
