ELECTROHYDRAULIC CONTROL SYSTEM OF GEARBOX WITH DUAL CLUTCH

摘要

FIELD: transportation.;SUBSTANCE: invention relates to automotive transmissions. Electrohydraulic dual clutch gearbox control system contains a mechanically-driven pump, two-position main valves electrically controlled to communicate with the hydraulic line of the hydraulic cylinders of the gear clutches, on-off valves electrically controlled to communicate with the hydraulic line of hydraulic cylinders of friction clutches of dual clutch, two-position additional valves with hydraulic control by means of a three-position directional valve with manual control. Outputs of additional valves are communicated with the hydraulic cylinders of the gear clutches and with the hydraulic cylinder of the friction clutch. Inputs of additional valves are connected to the pressure line when they are switched on, and when the additional valves are turned off, their inputs are communicated with the outputs of the main valves.;EFFECT: increased reliability of the gearbox.;8 cl, 2 dwg
