A pair of left and right operating levers (steering levers) 4.4'
The lower ends of the shafts 5. and 5. are respectively supported by bearings 6.6'.
The control levers 2.2' of the left and right variable displacement hydraulic pumps (hereinafter referred to as variable hydraulic pumps) 1.1' are each connected to one end of the rod 33' by a pin. The other end of the rod 3.3' is connected to the operating lever 4.4' by an intermediate partial pin near the lower end.The variable hydraulic pumps 1.19 each operate a hydraulic transmission via a closed circuit (not shown). It is connected to a hydraulic motor for traveling.

When moving the vehicle forward, use the left and right operating levers 4.4'.
At the same time, tilt forward (in the direction of arrow F) and hold. The traveling speed is controlled by tilting the operating lever 4.4'. Steering is effected by returning one of the control levers to reduce the speed, and braking is effected by simultaneously returning both control levers 4.4' to the neutral position.

Although the vehicle is driven by the above-mentioned operations, when traveling long distances, it becomes a pain for the driver to hold the left and right operating levers 4.4' for a long time. Therefore, it is conceivable to lock the nose 4.4' by operating both levers, but when steering, you must unlock one operating lever, and when applying the brakes, you must unlock the operating lever on one side. After releasing both locks, both operating levers 4.49 must be returned to neutral at the same time. When applying sudden braking, there is a risk that the lock will not release and the vehicle will run away due to the hurry.

When the vehicle moves forward, move the operating lever 18 to the position shown in Fig. 3b.
Push down the grip 18C against the spring 11b in the direction of the arrow shown, and then push it forward (in the direction of arrow F) to release the restraining rod 1.
gm is prevented from fitting into the engagement groove 20bJ. The engagement groove 20b is located at the maximum running speed, but if you want to obtain an intermediate running speed, an engagement groove is provided between the engagement grooves 20m and 20b.
By fitting the restraining rod 1gM into the engagement groove, any desired intermediate traveling speed can be obtained. Operation lever 18
When it is restrained by the engagement groove 20b, the shaft 15 rotates, the cylinder body 11.11'' is swung through the clamping lever 13.13'', and the rod 9.9° is rotated through the coil spring 21. is pulled forward.As a result, the shaft 5.5' is rotated in the same direction as the shaft 15 via the lever 7.7', and the operating lever 4.4' is tilted forward (in the direction of arrow F). Therefore, 0tsudo 3.3' is strained and the control lever 2.2 is
' swings, pressure oil is discharged from the variable hydraulic pump 1%1', and forward movement is performed. At this time, lever 8.8°
The bottle parts 81, gb, 8'Jl, and 8'b each rotate 1. (distance from the center of the long part to the end), and the pin part 83%V

During the aforementioned forward movement, for example, when turning to the right, the control lever 2 is swung in the neutral direction by returning the operating lever 4 to the neutral direction, and the discharge amount of only the variable hydraulic pump 1 is reduced. At this time, the shaft 5 also rotates, and the lever 9 is pulled (V) via the lever 7, but the operating lever 18
0b, and the shaft 15, clamping lever 13, and cylindrical body 11 are fixed, so the coil spring 21 is compressed and the rod 9 moves. Since the variable hydraulic pump 12 remains uncontrolled, the vehicle turns to the right.

When turning to the left, operate IE 4' to return it to the neutral direction. In this way, turning to the left will be performed in the same way as when turning to the right. To control this, the discharge amount of the variable hydraulic pumps 1% and 11 should be simultaneously set to zero; It is necessary to return the control levers 2, 2' to the neutral position. Figure 5a is moving forward, Figure 5b is moving backward,
Figure C shows the rod with an elongated hole 10.10 during a right turn (pivot turn) and Figure 5d shows the rod with an elongated hole during each operation during a left spin turn.
g, shows the relative position of the lever 8.8 and the pedal 16. To brake from each of these driving states, it is sufficient to simply depress the pedal 16 without operating the operating lever 18.4.4 - control lever 2.2. I will explain about it.

When it is time to apply the brakes while the vehicle is moving forward, the pedal 16 is depressed in the direction of arrow G to the position indicated by the chain line on the top stopper 22, as shown in FIGS. 4a and 51. As a result, the lever 12 swings in the counterclockwise direction shown by the arrow H in Figure 5a, the elongated rod 10.10' is pulled up, and the pin parts 8a, 8'a are moved upward. 8b%g'b is moved downward in the direction shown by the arrow ■ to the position shown by the chain line,
The lever 8.8' becomes horizontal and returns to the neutral position. That is, when the bin portion 8a, 8°1 returns to the neutral position, the shaft 5.59 rotates, the control lever 2.2' returns to the neutral position, and the vehicle stops.

In any of the above cases, the rod 9.9' moves, but the coil spring 21 of the cylindrical body 11% 111, which is locked to the rod 9.9', is compressed, as in the case of the pivoting motion. Therefore, the control lever 2.2' can be returned to the neutral position and the vehicle can be stopped without removing the operating lever 18 from the engagement groove of the fixed restraining plate 20.

If you want to open and stop the operation lever 1M for a while, hold the operating lever 1M in the engagement groove 20M. If you want to install the driver's seat of the vehicle in the opposite direction, set it in the opposite direction to the shaft 14 as shown in No. 5e@. A stopper 24 is installed in the opposite direction to the shaft 14. - As an example, to explain the case corresponding to the case where the vehicle is moving forward in Fig. 5a, by depressing the pedal 23 in the direction of arrow J to the locking position, the lever 12 is swung in the direction of the arrow and braking is performed in the same manner. Can be done. In this case, the elongated holes 10, 10' are pushed down and the bottle part 8
b, s'b are moved downward and the bottle parts 8a, 8'a are moved upward in the direction shown by the arrows to the position shown by the chain line, the lever 8.8' becomes horizontal, and braking is performed.

なお、操作レバー4.4′を同時に中立位置に戻しても

As explained above, according to the present invention, the operation lever 1
Since the vehicle can drive with the control lever 18 restrained in the engagement groove of the fixed restraint plate 2o, the driver does not get tired and can perform steering and braking operations without removing the control lever 18 from the engagement groove. Therefore, operation in an emergency becomes easy and safe. Furthermore, you can easily perform the opposite operation by simply flipping the pedals in the opposite direction.
