ABSTRACT:
A hydrostatic-mechanical drive for a load, e.g. a self-propelled machine such as a concrete mixer comprising a hydrostatic motor which can be connected to the load via a mechanical transmission. According to the invention, the shaft of the hydrostatic motor extends into the control plate or cover thereof (through which hydraulic communication is made with the drum carrying the axial pistons of the motor) and is provided with an inductive sensor on this plate to form a pulse generator (with a metal gear on the shaft) whose output represents a parameter of rotation of the motor.
