Abstract

PURPOSE:To improve steering performance by operating a hydraulic cylinder provided across both the axle of a work truck and the direction change member of a wheel upon sensing the angle in directional change of the work truck against a tractor whereby controlling the directional change of the work truck. CONSTITUTION:The tip end of a pitch 46 is pivotally secured on a draw-bar 47 provided to the rear section of a tractor wherein the angle of the pitch 46 can be detected by a pitch angle sensor 12. And a hydraulic cylinder 34 is provided across both the axle 32 of a work truck drawn by the tractor and a direction change member 33 provided on a wheel 40 and furthermore, a tire angle sensor detecting the turning angle of the wheel 40 is provided. Said tire angle sensor is composed of each switch 20 and 20 for right and left articulation operated by a cam which is integrally combined with a king pin pivotally securing the axle 32 with the wheel 40, and of a switch 8 for straight ahead running. Then, the hydraulic cylinder 34 is controlled by an actuating circuit through a changeover valve 10 based on the output from the pitch angle sensor 12 whereby the directional change of the work truck is controlled.

[Detailed Description of the Invention] [Industrial Application Field] The wheels of a working machine that follows a tractor are changed according to the direction change of the tractor, and even if the direction change of the tractor occurs, the wheels of the working machine are kept at a certain angle. This invention relates to a wheel steering method for a tractor-pulled working machine that can be converted.

However, when turning in the pillow tb, each time the operator enters the ridge again and starts work, the operating angle of the steering can be determined by checking the steering angle display board attached to the front of the machine, or by controlling various hydraulic valves while looking at the tires. Then I had to get back on track. This left major problems such as the fatigue caused by looking back and the decrease in work efficiency due to the loss of time.

It changes the direction of the tractor's direction change angle with respect to the work equipment to change the direction of the work equipment's wheels to right, go straight, or left.
In addition, by making it possible to maintain the direction change of the wheels up to a certain angle even if the tractor direction change angle changes, it is possible to turn the tractor handle and operate the hydraulic cylinder located at the corner between the work equipment and the tractor. Then, the wheels of the work equipment are turned in the opposite direction to the direction in which the tractor turned, and the work equipment is rotated forward in that state.

After that, even after the tractor has finished turning, the work equipment continues to turn, so when the tractor has finished accompanying the handle and the direction change angle begins to return to its original value, the solenoid valve is activated at the same time. If the wheels are returned to a straight-ahead state, the work equipment will not complete the rotation, so even if the tractor's direction change angle changes, maintaining the state in which the wheels have changed direction to a certain angle will solve the problem. This is the solution.

After that, when you tow the work equipment with the tractor and turn it around to start the next work (explained based on the case of left turn), if you turn the tractor handle to the left and turn,
The drawper rotates together with the tractor, so it rotates to the left (counterclockwise) relative to the hitch. The operating piece or switch attached to the drawper also rotates to the left (counterclockwise) along with the drawper relative to the hitch.
Therefore, when the switch or operating piece installed on the hitch is rotated by a certain angle (for example, 45 degrees), it closes the right-turn switch of the solenoid valve, which closes the right-turn circuit of the solenoid valve, switches the valve, and connects the oil package to the work equipment. Oil is pumped into the right-turn oil chamber of a hydraulic cylinder installed across the axle and wheel direction-changing member, which extends the rod of the cylinder, causing the direction-changing member to rotate the wheels of the work equipment so that it runs in the right-turning direction. In order to move, the cam attached to the king pin that pivotally connects the axle and the wheel rotates and closes the straight-ahead switch attached to the axle, which closes the relay and holds the relay installed in parallel to the relay. , the solenoid valve for the right turn continues to operate. Therefore, the right-turn solenoid valve remains in the same state and continues to pump oil into the right-turn oil chamber of the cylinder, so that the working machine turns with the wheels in the right-turn direction by the action of the cylinder rod. During this operation, the left-turn switch approaches or passes the straight-ahead operating portion of the cam, but at this time the left-turn switch does not close.

When the straight-ahead switch and the left-turn switch come close to the left-turn actuating portion of the cam or stop, the left-turn switch closes and the straight-ahead switch opens and stops operating.

Then, when the handle is turned back to the right to change the direction of the tractor in a straight line, the right turn switch installed on the drawper or hitch, which had been closed until now, opens, and when the handle is rotated further by a certain angle (for example, 0 to 20 degrees), the drawper or hitch opens. The straight forward switch on the hitch closes. At this time, the left turn switch installed at the king pin of the wheel of the work equipment is closed, so the left turn solenoid of the solenoid valve is activated, retracting the rod, and the wheel of the work equipment turns to the left.
The left turn switch provided at the kingpin opens, the straight forward switch closes and the relay closes, and the relay provided in parallel with the relay is held and the left turn solenoid valve continues to operate.

Therefore, the left-turn solenoid valve remains in the same state, and oil continues to be pumped into the left-turn oil chamber of the cylinder, so the cylinder rod causes the wheels of the machine to return to the straight direction as it runs. return. When the cam's straight-ahead operating section approaches the straight-ahead switch or stops, the straight-ahead switch is opened, the relay is turned off, the operation is stopped, and the vehicle moves straight.
