WebTractive Effort. Definition: Tractive effort is defined as the force at the rims or the outer edges of the driving wheels of moving trains. In other words, it is the sum of the tractive … Webto determine the total tractive effort (TTE) requirement for the vehicle: TTE [lb] = RR [lb] + GR [lb] + F. a [lb] where: TTE = total tractive effort [lb] RR = force necessary to …
WebSep 13, 2007 · Specifically, horsepower is TE in pounds times speed in miles/hour divided by 375. So that sets some sort of ceiling to the tractive effort of any diesel. Looking at Al Krug's C44, its 4400-hp rating means around 4100 hp at the wheel rim in its most powerful speed range. That sets an absolute limit to its TE; every other consideration subtracts ... WebThe tractive effort is obtained by multiplying the torque by the total ratio of power train and dividing this sum by the rolling radius of the driving tyres. Where: T= Motor torque in …
