Tractive Power

Tractive Power

 

the power developed by a vehicle on a towbar; the product of tractive force and the average speed of the vehicle. Tractive power depends on the power of the engine, the efficiency of the transmission, and the type of propulsion device. The maximum tractive power, which is one of the main performance indexes, is usually limited by the adhesion weight of the vehicle.

The Mercedes 9G-TR0NIC transmission--a nine-speed that features a torque converter with an efficiency of converting engine power to tractive power of 92%, which is an improvement over the circa 2003's 7G-TRONIC's of 85%--required the development of some sophisticated metalcutting in order to be built.
Shortly after its independence, Zimbabwe received more than $41 million (in two tranches in 1981 and 1982) so that its parastatal, National Railways of Zimbabwe could increase tractive power by acquiring new locomotives.
The battery pack provides electrical energy to the motor which in turn generates tractive power. Besides, the engine operates on a constant speed, constant load mode, maximising engine efficiency irrespective of large variation in vehicle speed and frequent stops and starts.
