Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a vehicle control device that switches and intermittents power to the vehicle's traveling gear between forward and forward motion.

(Prior art) As a control device for this type of vehicle,
There are techniques such as those described in Publication No. 11353, but in these techniques, the operating direction of the traveling clutch lever that switches the traveling device back and forth is the same, and the distinguishability is poor. When a driver is positioned in front of or behind the travel clutch lever and operates the travel clutch lever, the direction of operation is reversed when viewed from the driver, and there is often a risk of erroneously operating the travel direction.

(Problems to be Solved by the Invention) This invention aims to solve the above-mentioned drawbacks of the prior art, and also to reduce the amount of rotation of the traveling clutch lever to achieve quick operation.

(Means for Solving the Problems) An engaging piece 15 is provided on the culm of the running clutch lever 3 which is pivotally supported on a support shaft 13 and is rotatable in the front and rear directions from a neutral position and can be tilted in the left and right directions. A pair of actuating tools 27, 27, which are selectively engaged with the engagement piece 15 by tilting the traveling clutch lever 3 in the left-right direction, are pivoted on the supporting shaft 17 located above the supporting shaft 13, thereby operating the traveling clutch lever. A vehicle control device is provided on both the left and right sides of the vehicle 3, and the actuating devices 27, 27 are respectively connected to clutches that switch on and off the power to the traveling device 6 for forward or reverse travel.

(Operation of the invention) When the vehicle is moved forward or backward, when the traveling clutch lever 3 is rotated from the neutral position forward or backward about the support shaft 13, the actuating tools 27, 27 are selectively engaged and rotated. The traveling device 6 is moved forward or backward by intermittent engagement of the forward or reverse clutch.

(Effects of the invention) Since this invention is configured as described above, the vehicle is moved forward or backward by rotating the travel clutch lever 3 back and forth from the neutral position, so the driver can move the travel clutch lever 3 forward or backward. When the clutch lever 3 is operated from a position in front or behind the clutch lever 3, the operating feeling of the clutch lever 3 does not change and erroneous operation is less likely.

Further, when the traveling clutch lever 3 is rotated back and forth from the neutral position in this manner, the amount of rotation of the traveling clutch lever 3 increases, but the operating tool 27 that is engaged with the traveling clutch lever 3 increases. ，
Since the supporting shaft 17 of the traveling clutch lever 3 is located above the supporting shaft 13 of the traveling clutch lever 3, the actuating tools 27, 27 necessary for engaging and disengaging the clutch are activated by only slightly rotating the traveling clutch lever 3. The amount of rotation can be secured and the operation can be performed quickly.

(Example) Next, an embodiment of this invention will be explained with reference to the drawings.

The vehicle in this embodiment is a transport vehicle, and a loading platform 7, a driving unit 8 containing a built-in motor, a seat 9, and a control platform 2 are mounted on a vehicle body 1 equipped with a traveling device consisting of crawlers 6. A control platform 2 is provided at the front of the vehicle body 1, and allows the driver to operate the vehicle while sitting on a seat 9 or standing outside the vehicle body. The control platform 2 is provided with a travel clutch lever 3 and left and right side clutch levers 4 and 5.

The base of the traveling clutch lever 3 is loosely fitted and supported by a traveling clutch lever support shaft 13 pivoted between left and right support members 11 and 12 provided inside the control platform 2. An engagement piece 15 having an elongated engagement hole 14 at the front and rear is fixed in the middle of the culm of the traveling clutch lever 3. An actuator 27 having an engagement pin 16 that engages with the elongated hole 14 of the engagement piece 15 is rotatably pivoted to side clutch lever support shafts 17, 17 provided above the travel clutch lever support shaft 13. , connecting rods 18, 18, tension springs 19, 19, wire 2
0 and 20, and if one actuating tool 27 is connected to the driving clutch that moves the vehicle body 1 forward, the other actuating device 27 is connected to the traveling clutch that moves the vehicle body 1 backward. Therefore, the traveling direction of the vehicle body 1 can be changed back and forth by tilting the travel clutch lever 3 left and right in the neutral position and engaging the engagement pieces 15 with the left and right actuation tools 27 and pushing them forward or pulling them toward you. .

When the operator is sitting on the seat 9 facing the control platform 2 and is operating the vehicle, the vehicle body 1 will move toward the control platform 2 by pulling the travel clutch lever 3 toward the driver.
Conversely, if you push the traveling clutch lever 3 forward, the vehicle body 1
The vehicle advances toward the loading platform 7 side.

When driving on a dangerous mountain road, etc., the driver gets off the vehicle body 1 and controls the vehicle from the opposite side of the control platform 2. In this case, the driver moves the travel clutch lever 3 toward the driver's side. If the driver pulls the lever, the vehicle body 1 will move toward the loading platform 7, and if the travel clutch lever 3 is pushed, the vehicle body 1 will advance toward the control platform 2.

Therefore, in both riding and walking maneuvers, if the traveling clutch lever 3 is pulled toward the driver, the vehicle body 1 will move toward the driver's front, and conversely, if the traveling clutch lever 3 is pushed, the vehicle body 1 will move toward the driver's side. In either case, the operator can operate the vehicle with the same feeling of operation, and there is no risk of erroneous operation.

The bases of the left and right side clutch levers 4 and 5 are rotatably supported on a side clutch lever support shaft 17 that passes through the support members 21 and 21. Projecting rods 22, 22 that project forward and backward are fixed to the bases of the side clutch levers 4, 5, and the engaging pins 23 provided on the projecting rods 22 are loosely fitted into the long holes 25 of the connecting rods 24 for connection. The pair of connecting rods 24, 24 are connected to a side clutch provided on the drive section of the vehicle body 1 by a single wire 26. Therefore, whether the left and right side clutch levers 4, 5 are pulled forward or pushed forward, the side clutch on the operated side clutch lever operates and the vehicle body 1 turns toward the operated side.
Regardless of whether the operator is in the riding position or the walking position, pulling the right side clutch lever 5 toward you will cause the vehicle body 1 to turn to the right, and pulling the left side clutch lever 4 toward you will cause the vehicle body 1 to turn to the left. It becomes.

28 is a speed change lever that changes the running speed of the vehicle body 1, and 29 is a brake lever that brakes the vehicle body.

In this way, in this invention, the actuating tool 2 is provided with the engaging tools 15 fixed to the traveling clutch lever 3 on the left and right sides.
7 and 27 to rotate the traveling clutch lever 3 back and forth, the operation is easy, and the support shaft of the actuating tool 27, that is, the side clutch lever support shaft 17 is connected to the traveling clutch lever 3. 3, the operating angle of the traveling clutch lever 3 can be made small.
