Abstract

PURPOSE:To aim at smooth speed change and start-up by decreasing gradually the automatically controlled clutch operating force when the artificially controlled clutch operating force is added in a device such that the contact break of a clutch at the time of speed change operation can be controlled either automatically or artificially. CONSTITUTION:In a tructor, the torque of an engine 1 is transmitted to a driving wheel 4 through a main clutch 7 and a main and a sub transmission gears 2, 3 as well as transmitted to each driving part of an operating device 6 through a PTO clutch 8 and a PTO transmission gear 5. The main clutch 7 is controlled by means of the clutch control device in a control box 17. In the clutch control device, the main clutch 7 is contact broken by means of a cylinder E when the transmission gear shift of the main and sub transmission gears 2, 3 is specified. On the other hand, when the footing of a clutch pedal 15 is detected by means of a clutch operating switch while this automatic control is performed, the clutch control device is constructed such as to enable to stop the contact break operation of the main clutch 7 gradually.

[Prior Art] There are traveling vehicles such as tractors in which clutch engagement and shift conversion are automatically performed when a gear shift is set using a push-button setting device or the like. Normally, this type of power vehicle is also equipped with a clutch pedal for artificially engaging and disengaging the clutch, and if this clutch pedal is depressed during clutch operation under the above-mentioned automatic control, the clutch operation under the automatic control will be temporarily interrupted. It is set to be removed. In other words, clutch operation under human control is given priority over clutch operation under automatic control.

It is input to the CPU 21 via the D converter 2p, and when a shift is set by the operation switch 22 of the main and auxiliary transmission, it is output to the solenoid valve E and the main clutch 7
It is output to solenoid valves A-D so that the set shift occurs. Further, when the main clutch operation switch 23 is turned on by depressing the clutch pedal 10 during the automatic control, the engagement/disengagement operation of the main clutch 7 by the cylinder E is stopped. However, the excitation voltage of the solenoid valve E is adjusted so that even when the cylinder E is stopped, the operating force of the cylinder E does not suddenly drop to zero but gradually decreases over a predetermined period of time. At this time, the operating force gradual reduction speed and time can be appropriately set in advance.

C. Effects of the Invention As is clear from the above explanation, the clutch control device according to the present invention is configured to gradually reduce the clutch operating force through automatic control when a clutch operating force is applied through human control such as a clutch pedal. This makes it possible to shift gears and start smoothly. Additionally, there is no longer any danger of the operator's legs hurting due to the reaction from the clutch pedal when switching from automatic control to manual control.
