This relates to the automatic speed governor of i.

(Prior Art) Some motorcycles are equipped with an automatic speed governor that automatically maintains the traveling speed of the heavy vehicle at a constant level in addition to the accelerator operation using the accelerator grip.

This automatic speed governor controls the fuel supply system, which is operated by the accelerator operation of the accelerator grip, based on the output of the vehicle speed sensor. The system operates to adjust the amount of fuel supplied to the internal combustion engine, allowing it to travel at a constant speed.

(Problem to be Solved by the Invention) In this case, in addition to increasing and decelerating with the accelerator grip, if the automatic speed governor mechanism is activated by the l(+ control switch), this automatic speed governor mechanism The accelerator grip will rotate in conjunction with the operation.

In this way, the accelerator grip rotates in conjunction with the operation of the control switch that increases or decreases speed, and the control switch is operated with the hand holding the accelerator grip.
If the operating direction of the control switch is not set in consideration of the operating direction of the accelerator grip, the operability will be impaired.

This invention was made in consideration of this situation.
The present invention provides an automatic speed governor for a motorcycle that operates an automatic speed governor to improve the operability of a control switch that increases or decelerates.

(Means for Solving the Problems) In order to solve the above-mentioned problem, the present invention is equipped with an automatic speed regulating mechanism for driving a heavy vehicle at a constant speed, and according to the operation of the automatic speed regulating mechanism, f In an automatic, double-margin automatic speed governor in which an accelerator grip that increases and decelerates due to motion rotates in conjunction with the accelerator grip, a control switch that increases and decelerates is provided near the accelerator grip, and this control switch is moved in the axial direction of the handle. It increases and decelerates, and when accelerating, it moves outward of the handle as the accelerator grip rotates inward, and when decelerating, it moves inward of the handle as the accelerator grip rotates outward. It is characterized by the fact that

(Function) In this invention, a control switch is provided near the accelerator grip to operate an automatic 1-speed 1-speed mechanism to increase and decelerate, and this control switch operates in accordance with the inward rotation of the accelerator grip when increasing speed. Move the handle outward. In addition, during deceleration, it moves in the direction of the internal force of the handle in accordance with the outward rotation of the accelerator clip. In this way, when operating the control switch to increase or decelerate using the automatic speed regulating mechanism,
The direction in which the blade moves as the accelerator grip rotates is the same as the direction in which the control switch moves, making the control switch easier to operate.

(Fruitful Example) Hereinafter, an embodiment in which the present invention is applied to an automatic uniform profit margin will be described in detail based on the accompanying drawings.

In Fig. 1, a display device 2 is arranged on a motorcycle with a handle 1, and this display device 2 includes extrapolation indicators such as a traveling speedometer, a mileage totalizer, and a direction indicator. Warning indicators, etc. are installed.

An accelerator grip 3 and an operation switch section 4 are provided on the U side of the handle 1.

As shown in FIGS. 2 and 3, the accelerator grip 3 is
It is connected to the accelerator joint 5 by an opening actuation cable 6 and a closing actuation cable 7. The accelerator joint 5 is connected to a pulley lO of a carburetor 9 provided in an internal combustion engine 8 by an opening actuation cable 11 and a closing actuation cable 12.

When the accelerator grip 3 is rotated inward A, the opening actuation cable 6 causes the accelerator seat (ind. 5) to rotate counterclockwise, which causes the carburetor 9 to be
The pulley 10 is rotated counterclockwise in one direction to open a throttle valve (not shown).

Therefore, the amount of fuel supplied increases and the rotational speed of the internal combustion engine increases to 1:H.

On the other hand, when the accelerator grip 3 is rotated outward B, the closing actuation cable 7 rotates the accelerator joint 5 clockwise, which causes the closing actuation cable 12 to actuate in the direction of closing the throttle valve via the pulley lO. to reduce the rotational speed of the internal combustion engine.

An actuator 13 constituting an automatic speed regulating mechanism is connected to the accelerator joint 5 by a drive cable 14, and the actuator 13 is connected to a vacuum pump 16 via a pipe 15. A solenoid valve 17 is connected to the pipe 15. This vacuum pump 16 and solenoid valve 17 are controlled by a control device 18, thereby driving the actuator 13.

The control device 18 is connected to a valve 22 via a power switch 19 of an automatic speed regulating mechanism, a fuse 20, and a main switch 21.
or connected.

As shown in FIG. 3 to FIG. 6, the supplementary operation switch 4 includes a kill switch 23 that stops the internal combustion engine in an emergency, a control switch 24 that controls automatic speed regulation, and a starter switch 25 that drives the starter motor. Or is provided.

The handle control switch 24 is biased by a spring (not shown) and is always located at the center, and when it is driven and pushed toward the inner and outer ports of the handle shaft, a control signal is output. That is, as shown in FIG.
When the A and B contacts are pressed, the specified 11
(carry out constant speed driving; fu control (, output No. E,
This control switch 24 is returned to the central position by a spring.

During this constant speed running, if the control switch 24 is pushed in the squid direction and the a and b contacts are in contact, a control signal for deceleration is output for that time, and the control switch 24 is pushed in the mouth direction and the a and b contacts are in contact.
, when the d contact is pressed, a control signal for speed increase is output for that time.

- After increasing and decelerating the power, push the control switch 24 toward the mouth, and when the control switch 24 returns to the center position by the spring, a resume control signal that returns to the li (quickly) set for the next cruise is output. be done.

Roughly, when the control switch 24 is pressed to cut off the A and C contacts, the automatic speed regulating control is canceled.

In the control by the control switch 24, the control device 18 controls the vacuum pump 16 and the solenoid valve 17 to generate a predetermined negative pressure based on the information from the heavy speed sensor 26.
This is done by rotating the axle joint 5 via the actuator 13.

In this control, when accelerating, the accelerator grip 3 is rotated 11 in the direction A by the rotation of the accelerator joint 5.
At this time, the thumb on the right rule has a force that pulls the handle outward (it is easy to move, and the control switch 24 is pushed toward the mouth with the thumb, making it easy to operate).

Furthermore, when accelerating, the accelerator joint 5 rotates in the opposite direction and the accelerator grip 3 rotates in the direction B, but at this time, the thumb can easily exert a force pushing the handle inward, and the control switch 24 can be easily pushed toward the mouth with the thumb.

In addition to operating the kill switch 23 and control switch 24, the automatic speed regulating control can be canceled as shown in FIG.

This can also be done by operating the clutch lever 29.

Further, the display section 30 indicating the operating state of the automatic speed regulating mechanism is the first one.
As shown in the figures and FIG. 3, it is disposed integrally with the cover 31 of the main switch 21 at the attachment part of the handle 1.

Next, the operation of this embodiment will be explained.

When automatic speed regulation is not set, accelerator grip 3
When the engine is operated to increase or decelerate, the pulley 10 of the carburetor 9 is rotated via the accelerator joint 5 to adjust the opening degree of the throttle valve.

When the control switch 24 is pushed toward the squid at a predetermined running speed, a set signal is output, and when the control switch 24 returns to its original central position, the set indicator 31b
lights up and the speed is set to automatic speed control. As a result, the vacuum pump 16 is operated by the control device 18, and the negative pressure of the actuator 13 is adjusted, so that the accelerator joint 5
Turn to set the throttle valve opening.

Then, the traveling speed is constantly detected by the medium speed sensor 27, the actual speed is compared with the set speed by the control device 18, and the vacuum pump 16 is controlled to increase/decrease the negative pressure so that the set vehicle speed is always achieved. , adjust the negative pressure of the actuator 13. As a result, the drive cable 14 sets the opening degree of the throttle valve to node A through the accelerator joint 5 so that both Φ travel at a constant speed.

In this control, when increasing the speed, the control switch 24 is pressed in the direction of the mouth with the thumb of the right hand and the state is maintained, but at this time the accelerator grip 3 is rotated in the direction of the direction through the accelerator joint 5. move. This accelerator grip 3
As a result of this rotation, a force is applied to the thumb of the handle 1 to pull the handle 1 outward, and the operation of pushing the control switch 24 toward the mouth with the thumb is easily performed.

Furthermore, when decelerating, the control switch 24 is pushed in the squid direction and this state is similarly maintained, but at this time the accelerator joint 5 rotates in the opposite direction to that during the speed increase. As a result, the accelerator clip 3 rotates in the direction B, but at this time, the thumb can easily exert a force to push the handle 1 inward, and the operation of pushing the control switch 24 toward the mouth with the thumb is 8 steps. .

(Effects of the Invention) As described in n, the control switch provided near the accelerator grip is moved in the axial direction of the handlebar to increase or decelerate the speed, and when accelerating, the control switch is moved in the direction of the handlebar axis. When decelerating, the accelerator grip is driven to move inward in accordance with the outward rotation of the accelerator grip, so when accelerating or decelerating by operating the control switch, the accelerator grip rotates. The direction of movement of the hand accompanying the movement of the control switch matches the direction of movement of the control switch, making it easy to move the control switch and maintain it in a predetermined state;
Improved operability and layering.
