A study on the Analysis of Drive Efficiency by Drawbar Pull Test in the Wheeled Vehicle

경인력시험을 통한 차륜차량의 구동효율에 관한 연구

The drive efficiency is investigated with drawbar pull test to provide the basic data in the gradability and acceleration of the wheeled vehicle. As a result, the drive efficiencies are determined from 4*2 drive : Direct gear 0.89 1st gear 0.81 Other gears 0.83-0.87 4*4 high drive : Direct gear 0.85 1st gear 0.77 Other gears 0.79-0.83 4*4 low drive : Direct gear 0.83 1st gear 0.75 Other gears 0.77-0.81
