Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an electric gear shift operating device for a motorcycle.

(Prior art) In general, the gear change of a motorcycle is a mechanical process in which the driver grasps the clutch lever on the left side of the handlebar, disengages the clutch, and then depresses the shift pedal with his foot to rotate the shift drum little by little. This is done through manipulation.

However, in recent years, instead of the mechanical operation of pressing the shift pedal with your foot, a so-called electric transmission has been developed that uses an electric device such as a step motor to change gears electrically. ing.

Most operating devices for electric transmissions to date have a structure in which gears are shifted by pressing the shift switch with the thumb of the left hand while holding the clutch lever with the left hand.

However, operating the switch with only the thumb while holding the clutch lever is not necessarily easier than operating a switch such as a turn signal, which is performed by simply removing the thumb from the hand gripping the handlebar grip. Therefore, the driver's steering operation and attentiveness are adversely affected, which may even lead to an accident.

(Purpose of the invention) In view of the above points, the object of the present invention is to provide an operating device that allows a driver to perform gear shifting operations of a motorcycle having an electric transmission device more safely and easily. It is something.

(Structure of the invention) In order to achieve the above object, the present invention pivots the clutch lever so that it can rotate in the direction in which the clutch wire is pulled, and supports it so that it can swing in a direction crossing the said direction. , a switch is provided at a portion close to the swinging motion to switch the circuit when the actuator is pressed.

(Example) An example of the present invention will be described with reference to the drawings. A clutch lever 3 and a proximal end portion 4 of the clutch lever are attached to a handlebar 1 via bolts 2.
A clutch switch 5 is attached to a suitable location near the base end 4 with screws or the like. This clutch switch 5 is linked to the movement of the clutch lever 3. That is, when the clutch lever 3 is squeezed and the clutch is disengaged, the switch is turned on, and when the clutch lever 3 is released and the clutch is engaged, the switch is turned off.

Next, the base end portion 4 has a bifurcated guide portion 4a, and two microswitches 6 are attached to this guide portion 4a. If this micro switch 6 is a type that switches the circuit by pressing the actuator 6a,
Of course, you can use other switches as well. Further, the micro switch 6 is installed so that it is located exactly above and below the clutch lever 3 when the driver is grasping the clutch lever 3 to disengage the clutch (the state shown by the dashed line in FIG. 2). There is.

Based on the above-described configuration, the electric shift operating device according to the present invention rotates the clutch lever 3, which normally rotates only in the direction in which the clutch wire is pulled, that is, in the horizontal direction, in the direction that intersects this, that is, in the vertical direction. The gear shift operation is performed by rocking the gear.

Next, a structure that enables this vertical swing will be described.

In FIG. 1, the clutch lever 3 and the tip 7 are shown.
and can swing together via a spherical sliding bearing 8. A concave groove 7a is provided in the tip 7, and the ball 9 is inserted into the coil spring 10.
is pressed through the presser plate 11. Therefore, in a normal state, as shown in FIG. 3, the ball 9 is pushed into the groove 7a by the force of the coil spring 10.
Since the clutch lever 3 is pressed by the clutch lever 3, the clutch lever 3 maintains a horizontal state without tilting at any angle in the vertical direction. Then, in order to shift gears, the driver, while gripping the clutch lever 3, moves the clutch lever 3 upward by a slight angle as shown in FIG. Tilt downward through. Similarly, when the clutch lever 3 is moved downward by a slight angle, the tip 7
will tilt upward. Then, when the driver releases his hand from clutch lever 3, coil spring 1
0 force keeps the clutch lever 3 in its original horizontal state.

Next, the operation of the electric shift operating device as described above will be explained. First, when the driver wants to increase the gear (speed up), he/she grasps the clutch lever 3 and rotates it horizontally, disengaging the clutch and turning on the clutch switch 5. Then, while gripping the clutch lever 3, swing the clutch lever 3 upward (in the direction of the arrow U in FIG. 1) by a slight angle and press the actuator 6a of the micro switch 6. 6 is turned on. Then, the electric shift operating device operates via the controller 12 electrically connected to the micro switch 6 to shift up the gear. Also, if you want to lower the gear (decelerate), press the clutch lever 3 in the same way.
All you have to do is to swing the clutch lever 3 downward (in the direction of the arrow D in FIG. 1) by a slight angle while gripping the lever. In this way, by providing the clutch switch 5 between the micro switch 6 and the controller 12 as shown in the circuit diagram of FIG. 5, the electric gear shift operating device according to this embodiment allows the driver to perform gear shifting operations more reliably. I take it as a thing. That is, even if the contacts U or D in FIG. 5 are closed, the controller 12 will not operate as long as the contacts of the clutch switch 5 are open.

Therefore, even if the driver half-heartedly swings the clutch lever 3 in the vertical direction without fully grasping the clutch lever 3 to the position where the clutch is released, and turns on the micro switch 6, the clutch switch 6 Since the switch is not turned on, the electric transmission does not work and the transmission mechanism will not be damaged.

(Effects of the invention) The invention is constructed as described above,
Conventionally, the clutch lever was designed to only move in the direction in which the driver squeezed the clutch wire and pulled the clutch wire, but by making the clutch lever swingable in a direction that intersects with that direction, the driver's gear shifting operation is now easier. This has the effect of facilitating operation and improving operability.
