The linkage mechanisms with internal driving link that are used in many different machines are considered in the paper. The mechanism contains hydraulic cylinder that is hinged to the rack, a rocker arm that is pivotally attached to the driving rod and to the rack. The law of motion of a rod in a hydraulic cylinder was synthesized. The positions, angular velocities and accelerations of the hydraulic cylinder and the rocker arm are analytically determined by the methods of engineering mechanics and the theory of mechanisms and machines. Thus, brief analytical dependencies are obtained. It is shown that the angular accelerations of the hydraulic cylinder and the rocker arm are qualitatively similar to the relative acceleration of the rod. The results of the work can be used in the motion research of hydraulically driven excavator buckets, other lifting and loading, road building machines, in the actuating mechanisms of industrial robots.
