Abstract

PURPOSE:To make a motorcycle perform its constant speed running in a way of locking a throttle grip to a specified rotating position temporarily, by installing a set switch in an exciting circuit of an electromagnet. CONSTITUTION:To lock a throttle grip 6 in position, first an exciting circuit is closed, then operation on closing a main switch 22 and a set switch 24 takes place. If doing like this, as an on-off switch 18 is closed all the time, a solenoid 14 is locked by attracting a friction plate 10, locking the throttle grip 6 at a specified rotating position. In addition, this condition is left intact, the grip 6 also can be rotated against magnetic force of the solenoid 14. Moreover, in time of emergency, with a brake or a clutch operated, a switch 26 or 28 is opened and thereby a magnetic field of the solenoid 14 can be demagnetized and as a result, a void is produced between the solenoid 14 and the friction plate 10 by dint of an energizing device 12 so that the lock of the throttle is released.

Description

[Detailed description of the invention] This invention relates to a constant speed traveling device for motorcycles.

In particular, the present invention relates to a constant speed traveling device for a motorcycle, which is easy to operate for constant speed traveling and also easy to change over between increasing and decelerating.

Conventionally, there are the following constant speed traveling devices for motorcycles. The knob is provided with a fixing means for fixing the throttle grip rotated a predetermined amount, locking teeth are provided at one end of the throttle grip, the throttle grip is slidably fitted onto a handle bar, and the throttle grip is slidably fitted to one end of the handle bar. A locking piece is provided. and.

The lock teeth of the throttle grip rotated a predetermined amount and the lock piece of the handle rod are engaged with each other to temporarily fix the throttle grip.

Alternatively, a tapered hollow portion is formed in the axial direction at the end of the handle rod into which the throttle grip is slidably fitted, a taper pin is inserted into the tapered portion, and the throttle grip and the noddle rod are fixed. There is a device that makes it possible to maintain a constant speed of a motorcycle. - However, in any of the above-mentioned conventional devices, it is extremely difficult to fix or unfix the fixing means that maintains constant speed running, that is, to switch to acceleration or deceleration.

This had the disadvantage of distracting the driver's attention and potentially causing a traffic accident.

Therefore, an object of the present invention is to enable the motorcycle to run at a constant speed by temporarily fixing the throttle grip at a predetermined rotational position using an electromagnet when necessary, and to enable the motorcycle to run at a constant speed by using a set switch or at least a brake operation. To realize a constant speed traveling device for a motorcycle that can quickly release the fixation of a throttle grip by opening the excitation circuit of a front electromagnet.

The present invention will be described in detail below based on the drawings. 1st.
FIG. 2 shows a first embodiment of the present invention, and in FIG. is handle 2
and the sliding surface of the sliding tube 4.

Reference numeral 6 denotes a throttle grip fixed to the outer peripheral surface of the sliding tube 4. A wire winding plate 8 is fixed to the outer peripheral end of the sliding tube 4, and a friction plate 10 is fixed to the side surface of the wire winding plate 8. Also, on the outside of the friction plate IO.

-16, and the cover 16 is fixed to the outer peripheral surface of the handle bar 2.

Next, the excitation circuit for the solenoid 14 shown in FIG. 1 will be explained. Connect the solenoid 14 to the power supply 20.

In this circuit, a normally closed electromagnetic switch 18. Main switch 22. A set switch 24 is then provided in series.

Further, the electromagnetic coil 19 of the electromagnetic switch 18 is connected to the t source 2.
0, and a brake switch 26 and a clutch switch 28 are interposed in series in this circuit.

Note that 30 is a throttle wire.

Next, the effect will be explained. To fix the throttle grip when the vehicle reaches a desired speed, the excitation circuit is closed and the main switch 22 and set switch 24 are closed. By the way.

Since the switch 18 is normally closed, a current is applied to the solenoid 14 and a magnetic field is generated. Therefore, the solenoid 1
4 attracts and fixes the friction plate 10, and the throttle grip 6
This is to fix the Pi leg at the rotating position.

Also, in this state, the throttle grip 6 can be rotated against the magnetic force V of the solenoid 14.
Operate like this to perform acceleration/deceleration operations.

It is also possible to fix it at a predetermined rotational position.

Furthermore, in an emergency, by operating the brake or clutch, the brake switch 26 or clutch switch 28 can be opened and the magnetic field of the solenoid 14 can be extinguished. A nitrogen gap is created between the throttle and the lO, and the throttle is released.

Then, the throttle grip 6 is rotated in the υ deceleration direction by the biasing force of the cuff' spring, and deceleration is quickly performed. Alternatively, the switch 181 can be opened by opening the set switch 24.

This operation also allows constant speed automatic driving to be stopped.

FIG. 3 shows a second embodiment of the present invention, and the feature of this second embodiment is that the wire winding plate 8 is connected to the ratchet wheel 3.
2, in that the pin 34 is attracted and engaged with the pawl 32 by the magnetic force of the solenoid 14. When the main switch 22 and the set switch 24 are closed to form an excitation circuit, a magnetic field is generated in the solenoid 14, and the solenoid 14 resists the biasing means 12 and presses the pin 34.
is sucked in the meshing direction, the ratchet wheel 32 and pin 34 are brought into mesh with each other, and the ratchet wheel 32 is held at a fixed position.

In addition, if you want to increase/decelerate a little from this meshed state,...

This can be done simply by rotating the throttle grip 6. :) Mari, rattle wheel 32 of wire winding plate 8
By rotating the pin 34, the pin 34 is moved back and forth intermittently, and the engagement position between the ratchet wheel 32 and the pin 34 can be changed.

Well, in case of an emergency, if you operate the 9 brake or clutch as in the first embodiment, the brake switch 2 will be activated.
6 or clutch switch 28 is opened.

The magnetic field of the solenoid 14 is extinguished. Then, when the magnetic field disappears, the pin 34 is sent in the i direction by the biasing force of the υ biasing means 12, thereby releasing the mesh between the threadworm 32 and the pin 34. By releasing the engagement between the ratchet wheel 32 and the pin 34, the biasing force of the Gai cab spring 36 is applied to the accelerator wire 3.
0 in the deceleration direction, quickly rotate the E-IM upper plate 8 in the deceleration direction, and reduce 11! fulfill.

However, if it is constructed as in this second embodiment.

The magnetic force of the solenoid 14 may be relatively weak, which has the advantage of simplifying the configuration.

A third embodiment of the invention of the fourth A Yuko is shown, and its features are as follows. That is, a disk-shaped fixing plate 38 is fixed on the outer peripheral surface of the handle rod 2, a sliding tube 4 is provided that rubs the outer peripheral surface of the handle rod 2, and the outer peripheral end of the sliding tube 4 is provided. A disc-shaped solenoid 14 is fixedly installed. A throttle grip 6 is provided fixedly on the sliding tube 4. Sliding between the end of this throttle grip 6 and the solenoid 14! 11? A wire winding plate 8 is provided on the outer periphery of J-4.
The tabs are provided so as to be slidable so as to be able to freely rotate with respect to the sliding tube 4.

Further, the clutch switch in the excitation circuit described in the above embodiment is not provided in this embodiment.

If configured as in this third embodiment, the main switch 22
When the set switch 24 is closed when the set switch 24 is turned on, a magnetic field is generated in the solenoid 14, and the fixing plate 3B and the solenoid 14 are attracted and fixed. At the same time, the solenoid 14 and the wire winding plate 8 are similarly attracted and fixed. As a result, the throttle grip 6 and the wire winding plate 8 are able to interlock with each other via the solenoid 14, so the throttle grip 6 can be rotated to the desired engine speed and held at that position. This makes it possible to drive at a constant speed.

In an emergency, by operating the brake, the brake switch 26 opens and closes, cutting off the excitation circuit and extinguishing the magnetic field of the solenoid 14, and the biasing force of the gear spring 36 opens the accelerator wire 30. The wire winding plate 8 is moved in the deceleration direction, and at the same time, the wire winding plate 8 is rotated in the deceleration direction, thereby quickly decelerating the wire. As a result, even if the throttle grip 6 is pressed against the road surface due to a fall or the like and becomes locked, or a dangerous situation arises in which an inexperienced driver continues to hold the throttle grip tightly due to nervousness.

Since the wire winding plate 8 is rotatably provided on the outer peripheral surface of the sliding tube 4 on which the throttle grip 6 is fixedly attached, only the wire winding plate 8 can easily rotate in the deceleration direction. This prevents unnatural cylinder rotation of the internal combustion engine of a motorcycle after a fall, etc., and prevents the spread of an accident.

Note that a fall switch that is turned off when the two-wheeled vehicle falls may be provided in the excitation circuit.

With this configuration, even if the vehicle falls down without operating the brakes, the rotation speed of the two engines can be reduced, contributing to safe driving.

As described in detail above, the present invention provides the following effects.

(1) A solenoid is provided to fix the wire winding plate at a predetermined rotational position, a set switch is provided in the excitation circuit of this solenoid, and a brake switch is provided to cut off the excitation circuit by at least brake operation. The fixed operation is easy and allows the motorcycle to run at a constant speed easily and reliably, reducing driver fatigue during long distance driving, and reducing fuel consumption due to constant speed driving. can be accomplished. Also, I used an electromagnetic switch.

By simple operations such as brake operation, it is possible to easily, quickly, and reliably switch from a constant speed running state to increasing/decelerating running. Since the fixing and unfixing operations can be easily performed, the driver is not distracted by constant speed driving operations, which greatly contributes to safe driving.

(2) Also, there is no need to perform a special idle setting like in the past when idling, etc., and the throttle grip can be easily fixed in a predetermined position, allowing warm-up operation to be performed at the desired accurate rotation speed. This can be done reliably and easily.

(3) Furthermore, by configuring the engine as in the third embodiment, the engine can be kept at a low rotation speed in an emergency, making it possible to prevent further damage from spreading.
