Problems solved by technology

[0005] In the structure of the above-mentioned Patent Document 1, although there is no shift shock when the clutch pedal is returned, it is not considered that the centrifugal force generated by the rotation of the input shaft of the hydraulic clutch applies thrust to the clutch hydraulic piston, and the thrust affects the operation of the clutch pedal. The operating tactile situation when

Abstract

A vehicle is provided to employ a hydraulic pressure controller to calculate a centrifugal force of a hydraulic pressure clutch, correct a hydraulic pressure of the hydraulic pressure clutch, and operate the hydraulic pressure clutch from a non-contact state to a contact state by using the corrected hydraulic pressure. A vehicle includes an engine(62), a hydraulic pressure clutch(D), power transfer appliances(A,B,C), clutch manipulation units, return springs, and a hydraulic pressure adjusting unit. The hydraulic pressure clutch changes a contact state by adjusting a hydraulic pressure of working oil. The power transfer appliances operate by using power existing in a contact state of the hydraulic pressure clutch. The clutch manipulation units adjust the hydraulic pressure of working oil, in which the hydraulic pressure makes the hydraulic clutch in a contact state or a non-contact state. The hydraulic pressure adjusting unit outputs hydraulic pressure greater than an initial elastic force of the return springs, outputs hydraulic pressure corresponding to the elastic force of the return springs, and then gradually outputs a hydraulic pressure greater than the elastic force of the return spring.

Description

technical field [0001] The present invention relates to a work vehicle having a hydraulic control device for a hydraulic clutch that is excellent in operability in farms. Background technique [0002] Work vehicles for agriculture, construction, transportation, etc. have left and right running axles and a transmission device for changing the speed of the driving force of the running axles. As such a transmission device, a transmission device having the following structure is known. The power on-off main clutch and the reversing mechanism for forward and reverse conversion of the vehicle, and a synchronous meshing main transmission device is provided under the transmission of the reversing mechanism, and an auxiliary transmission device is also provided under the transmission. [0003] Among the above-mentioned work vehicles, there is a vehicle having a structure of a main clutch and a hydraulic clutch that doubles as a reversing mechanism for forward and reverse conversion. ...
