Title:
OPERATION METHOD FOR TRACTOR CLUTCH OPERATION DEVICE HAVING HYDRAULIC ASSISTANCE
Document Type and Number:
WIPO Patent Application WO/2016/141638
Kind Code:
A1
Abstract:
An operation method for a tractor clutch operation device having hydraulic assistance. According to a clutch pedal (1), a booster cylinder (5) is connected to a clutch pull rod (4) by means of a yoke (3), an output pipeline of a steering constant flow pump of a tractor provides a pressure to the booster cylinder (5), and a piston rod (15) of the booster cylinder (5) is connected to the clutch pull rod (4) by means of the yoke (3). When a driver steps on the clutch pedal (1), firstly power is provided to a throttling valve (15-2) in the clutch piston rod (15) to enable an upper cavity (13) and a lower cavity (14) in the booster cylinder (5) to generate a pressure difference, the piston rod (15) is pushed to pull the clutch pull rod (4), the clutch is separated, the easy control of the clutch is achieved, the torque reserve coefficient of the clutch is increased, the operation force of the driver is reduced, and the operation comfort of the driver is improved.
