Abstract. Steering kinematics and turning resistance torque depends on geometrical parameters, mass distribution and a type of suspension system of an articulated body steer vehicle with a combination of a ground type. It is important how does a driving system is designed because of its influences on wheels torque while turning. When a vehicle is turning an angle in an articulated joint is rising and the front and rear frame rotate themselves by an angle to the symmetry line when previously situated vehicle forward. In a paper, a method for front and rear frame measuring angles of rotation is presented. There are also results of turning resistances with different mass in articulated wheel loader bucket and two types of ground. Results show, that increasing of a wheeled bucket load influences both steering torque required for turning and changes angles of rotation of the front and rear frame of a vehicle. Steering torque at a first phase is measured to rise to maximum level then decrease even bucket load increase. We can observe that revolution angle of front and rear frame during steering depends strongly on a bucket load, ground type and driving system. Knowledge in rotation angles gives an opportunity to propose a mathematical model for future prediction turning resistance torques.
