ABSTRACT:
The invention relates to a concrete mixer truck having a mixer drum adapted to be rotated by the traction motor of the vehicle through an auxiliary transmission of the traction motor transmission. It is an object of the invention to ensure that the power supplied by the traction motor is effectively available for traction purposes under conditions of increased power demand, such as starting and accelerating, and/or that the torque of the mixer drum does not interfere with gear shift operations. To this effect the invention provides a control means adapted to disconnect the mixer drum rotating transmission from the traction motor transmission during predetermined travel conditions, i.e. under conditions defined by an increased power demand for locomotion of the vehicle. Also included in these conditions is each gear shift operation, as at this instance the torque of the mixer drum is prevented from influencing the rotary speed of the speed shift transmission.
