Abstract

The device is intended for use in railway transport with railway construction machines. It is with increased output and reduced labour consumption. The device includes a driving chain wheel (1) for the sprocket chain, mechanically connected to a hydraulic motor (2),connected to a delivery (3) and returning (4) oil pipeline with controllable hydraulic pump (5) and a second hydraulic motor (6), mechanically connected to the driving railway track shafts (7) of the machine. The second hydraulic motor (6) is connected to a delivery and returning oil pipeline (8) with a second controllable hydraulic pump (9) and a control handle (10),connected with a cable (11) to the steering lever (12) of the second controllable hydraulic pump (9). The steering lever (12) is hinged to a piston rod (13) of a single-acting hydraulic cylinder (14) with a return stroke spring (15), the hydraulic cylinder is connected by an adjusting screw to the machine frame and its inlet is connected to the delivery oil pipeline (3), connecting the first controllable hydraulic pump to the first hydraulic motor.
