Brake pedal stroke dependent inching system |
摘要 |
A inching system adapted for releasing a transmission clutch to disconnect engine power delivery in an industrial vehicle comprises a main pump for creating pump pressure; a brake pedal operated by a driver; a master cylinder communicating with the main pump through a pump pressure supply conduit for producing brake pressure in to perform a brake operation as the brake pedal is pressed; a charging pump for discharging clutch actuation fluid to be fed to the transmission clutch; an inching valve including a valve housing having a pilot chamber provided at a first end thereof to receive the pump pressure and a valve spool slidably fitted within the valve housing, the valve spool having a first operative position for feeding the clutch actuation fluid to the transmission clutch to engage the clutch and a second operative position for cutting off the clutch actuation fluid to release the transmission clutch when the pressure within the pilot chamber becomes higher than a predetermined valve; and a pilot conduit for interconnecting the pump pressure supply conduit and the pilot chamber.
