Hydraulic control system for a synchronizer |
摘要 |
A hydraulic control system for displacing a synchronizer into engagement with a rotating gear in a gearbox includes a hydraulic piston/cylinder unit mechanically coupled to the synchronizer, an electrically controllable pressure regulating valve for supplying hydraulic fluid to the piston/cylinder unit and an electrical control circuit acting on the pressure regulating valve to vary the pressure of the hydraulic fluid supplied to the piston/cylinder unit. In order to effect a rapid and smooth engagement of the synchronizer, the control circuit acts to increase the pressure of the hydraulic fluid supplied to the piston/cylinder unit progressively.
