CONTINOUSLY VARIABLE TRANSMISSION CONTROL

摘要

Electro-hydraulic continuously variable transmission control comprising: an electrically pilot operated transmission control valve, an electrically pilot operated clutch pressure control valve, an electrically pilot operated system pressure control valve and a control oil pump coupled to the machine which supplies the control oil, the transmission control valve, in the event of a power failure of the assigned pilot control valve in the open position, connecting the secondary circuit to the primary circuit in such a way that the same pressure prevails in both circuits, thereby ensuring maximum transmission.
