Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reversing device for a motorcycle or the like that uses a starter motor for engine starting as a power source.

"Prior Art" Large two-wheeled motor vehicles (motorcycles) are not easy to move manually, and it takes especially effort to pull the handlebars and move the vehicle backwards. For this reason, some large motorcycles are equipped with a reversing device that uses a motor to move backwards (for example, Japanese Patent Laid-Open No. 60-252079).
. In other words, the motor is used as a power source to move the vehicle backwards.

``Problems to be Solved by the Invention'' By the way, the right handle of a motorcycle is generally equipped with a throttle grip that must be operated while riding, so the starter switch and throttle grip, which are operated mainly when not riding, are installed on the right handlebar of a motorcycle. A switch etc. are provided. On the other hand, there is a turn signal switch on the left steering wheel that needs to be operated mainly while driving.
A horn switch, bashing switch, etc. are provided. Here, the optimum position for installing the reversing switch for starting the motor, which is the power source for reversing, is on the left handlebar, due to the convenience of handling the bike.

However, since the left handlebar is provided with a large number of switches as described above, there is little free space, and it has been difficult to provide a new back switch.

This invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a reversing device for a motorcycle, etc., in which a switch for turning on/off various loads such as a pawn (horn) can also be used as a reversing switch. It is an object.

``Means for Solving the Problems'' This invention provides a reversing device for a motorcycle or the like that reverses the vehicle body by reversely rotating the drive wheels using a starter motor for starting the engine, which supplies power to a specific load. When the rotational force of the starter motor is transmitted to the drive wheels and the drive wheels rotate in the reverse direction, the operation switch is disconnected from the specific load, and the operation switch is turned on/off. The present invention is characterized by comprising a switching means that connects the operation switch and the starter motor so that the starter motor starts/stops when the starter motor is turned off.

"Operation" When the rotational force of the starter motor is transmitted to the drive wheels and the drive wheels rotate in the opposite direction, the switching means disconnects the operation switch from the specific load and turns the operation switch on/off. When the starter motor is turned off, the starter motor starts/stops, and by turning on the operation switch and starting the starter motor, the driving wheels rotate in the opposite direction and the vehicle moves backward.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a circuit diagram showing the configuration of an embodiment of the present invention.

In this figure, R9 is a push-button type horn switch for blowing the horn H, and when pressed by the driver, the terminal HS is pressed.

and HS2 are electrically connected. CS is a changeover switch that disconnects the horn H from the pawn switch HS, and when the driver puts the gear in reverse, the common terminal C
8c and the terminal CSa, and in other cases, the common terminal C8c and the terminal C8b are electrically connected. That is, when the gear change pedal l is in the forward position (low, second, top, etc.) or neutral position as shown in FIG.
When there is continuity between sb and the gear change pedal I is depressed to the lowest reverse (back) position, the gear change pedal I is switched by the operating piece 2 provided on the gear change pedal I, and the common terminal C9c and the terminal Conductivity is established between C3a. SS is a push-button type starter switch, and when pressed by the driver to start the engine, the terminals S81 and SS2 are electrically connected.

BT is an in-vehicle battery, the negative terminal of this battery B'r is grounded, and the positive terminal is connected to the terminal I of the pawn I].
-1, is connected. The other terminal H2 of this middle horn (■) is connected to the terminal C8b of the changeover switch C8, and the common terminal C9c of the changeover switch C8 is connected to the horn switch I-I.
The other terminal HS2 of the horn switch I-IS is grounded. Then, when the horn switch Is is pressed, a drive current is supplied from the battery BT to the horn H via the changeover switch C8, and the horn tr sounds.

Further, M is a starter motor for starting the engine, and SM is a starter magnetic relay. A positive terminal of a battery I3T is connected to a terminal SM of this starter magnetic relay SM, and a first terminal of a starter motor M is connected to a terminal SM. Also starter magnetic relay S
One end of the coil c1 of M is connected to the positive terminal of the battery BT, the other end is connected to the terminal S81 of the starter switch SS, and the other terminal ss of the starter switch SS is grounded.

The second terminal of the starter motor M is the terminal R of the reversing relay R,
and R2. In this reversing relay R, when the coil C7 is in a de-energized state, the terminals R1 and R3 are electrically connected through the movable contact R5, and when the coil C1 is in the energized state, the terminals R7 and R4 are electrically conductive through the movable contact R5. It is conductive. Terminal R3 of this reversing relay R is grounded, terminal R4 is connected to the positive side terminal of battery BT together with one end of coil C7, and the other end of coil C6 is connected to terminal C9a of changeover switch C8. Then, from the state shown in the figure, the starter switch SS is pressed down, the coil C1 of the starter magnetic relay SM is energized, and its terminal S
When conduction occurs between M and &SMt, a current flows from the battery BT through the path of the starter magnetic relay SM's terminals SM, →SM, → starter motor M's first terminal, second terminal, and reverse relay R's terminal R+ = Rs. , whereby the starting motor M rotates in the forward direction.

Further, 5 is a chopper control circuit that controls on/off the power transistor Tr, its positive power terminal Ta is connected to the terminal R3 of the reversing relay R, and the control terminal Tb is grounded via the variable resistor VR. There is. Then, the coil C3 of the reversing relay R is excited, and its terminals R2 and R4 are brought into conduction via the movable contact R6, thereby causing the positive side IXEi
When terminal T a is connected to the positive terminal of battery BT,
The chopper control circuit 5 supplies a pulse signal having a pulse width or a pulse period set by a variable resistor VR to the base of the power transistor Tr, and controls on/off of the power transistor Tr.

The collector of the power transistor Tr is connected to the first terminal of the starter motor M, and its emitter is grounded.Then, the coil C6 of the reversing relay R is energized,
When the terminals R7 and R4 are electrically connected via the movable contact R6, as the power transistor Tr turns on/off,
From battery +3T, terminal R-= Rt of reverse relay R
- Current flows intermittently in the path from the second terminal of the starting motor M to the first terminal to the collector emitter of the power transistor Tr, thereby causing the starting motor M to rotate in the opposite direction.

Next, FIG. 3 is a perspective view showing the configuration of a transmission mechanism that transmits the rotation of the starter motor M. In this figure, a starter pinion 22 incorporating a one-way clutch 21 is provided at the tip of an output shaft 20 of a starter motor M. This one-way clutch 21 transmits the rotation of the output shaft 20 to the starter pinion 22 only when the starter motor M rotates forward and its output shaft 20 rotates in a direction in which the engine can be started (in the direction of arrow A in the figure). It is something to do. When the starter pinion 22 rotates in the direction of arrow A, the driven gear 23 meshing with the starter pinion 22 rotates, and the crankshaft (as shown in the figure) of the engine rotates.

On the other hand, if the cell motor M rotates in the reverse direction, its output shaft 20
The back pinion 24 provided at
Drive shaft 26 rotates. As this drive shaft 26 rotates, the drive wheels (as shown) rotate in the opposite direction, causing the vehicle to move backward. The driven gear 25 is provided with a one-way clutch 27, and the driven gear 25 operates only when the gear change pedal 1 shown in FIG. direction, and meshes with the back pinion 24.

In this way, when the gear change pedal 1 is placed in the back position, the rotational force of the starter motor M in the opposite direction is transmitted to the drive shaft 26, and when the gear change pedal 1 is placed in a position other than the back position. In this case, the forward rotational force of starter motor M is transmitted to the crankshaft of the engine. In other words, when the starter motor M rotates in the normal direction, it functions as a starter for the engine, and when it rotates in the reverse direction, it functions as a power source for reverse travel.

Next, the operation of the reversing device in the motorcycle or the like configured as described above will be explained.

(1) Engine Start To start the engine, the driver operates the gear change pedal I to set the gear to the neutral position or disengage the clutch, and then presses the starter switch SS. When the starter switch SS is turned on, conduction occurs between its terminals SS1 and SS3, and as a result, excitation current is supplied from the battery BT to the starter magnetic relay cover C1, and its terminals SM and 8M7
conduction between the two. As a result, as mentioned above, battery I3
From T to terminal SM of starter magnetic relay SM
1-S M 2 -> A current flows through the path of the first terminal of the starter motor M, the second terminal, and the terminals R1-R3 of the reverse relay R, and the starter motor M rotates in the forward direction. Then, the starter pinion 22 rotates in the direction shown by arrow A in FIG. 3, and this rotation is transmitted to the crank shaft of the engine via the driven gear 23, and the engine is started.

Here, when the horn switch H8 is pressed during the above-mentioned engine start and during normal driving thereafter, conduction is established between the terminals HS1 and HS, and the horn I] is connected from the battery BT via the changeover switch CS. A driving current is supplied to the horn 4, which causes the horn 4 to sound.

(2) Traveling in reverse When traveling in reverse, the driver depresses the gear change pedal 1 to the reverse position. Then, the changeover switch C8 is switched by the operating piece 2 provided on the gear change pedal 1, and the common terminal CSc and the terminal CSa are electrically connected.

Thereafter, the horn switch HS is disconnected from the horns ■-■ and loses its original function of making the horn 11 sound.

In this case, the driven gear 25 meshes with the back pinion 24 as shown in FIG. 3, and the rotational force of the starting motor M in the opposite direction is transmitted to the drive shaft 26.

In such a situation, the driver should press the horn switch HS.
When you press down, the terminal HS and R3 become conductive,
An excitation current is supplied from the battery BT to the coil C3 of the reversing relay R, which excites the coil C3 of the reversing relay R, and conducts between its terminals R7 and R4 via the movable contact R5. At the same time, power is supplied to the chopper control circuit 5, and from then on, the chopper control circuit 5 supplies a pulse signal with a pulse width or pulse period set by the variable resistor ■R to the base of the power transistor Tr. Controls on/off of the Tr.

As described above, as the power transistor Tr turns on and off, the path from the battery BT to the terminal R4 of the reversing relay R → R7 → the second terminal of the starter motor M → the first terminal to the collector emitter of the power transistor Tr Current flows intermittently, causing the starter motor M to rotate in reverse.

When the starting motor M rotates in the reverse direction, the back pinion 24 provided on the output shaft 20 rotates in the direction of arrow B, the driven gear 25 meshing with this rotates, and the drive shaft 26 rotates.

As the drive shaft 26 rotates, the drive wheels rotate in the opposite direction, and as a result, the vehicle moves backward.

In this case, the backward movement speed of the vehicle body can be appropriately set by adjusting the variable resistance VR.

In other words, by adjusting the variable resistor VR, the pulse width or pulse period of the pulse signal supplied from the chopper control circuit 5 to the base of the power transistor Tr is adjusted, and thereby the pulse signal supplied to the starter motor M is adjusted. The average current per hour is adjusted to adjust the rotational speed of the starter motor M, and as a result, the reverse speed of the vehicle body is adjusted.

Here, in the above-mentioned embodiment, an example was explained in which a changeover switch C8 is provided which changes when the gear change pedal l is placed in the reverse position, but the function of this changeover switch CS is provided in the main switch. It is also possible to For example, the main switch may be provided with a back position, and a switch that is switched when a key inserted into the main switch is turned to the back position may be incorporated into the main switch, and this switch may have the function of changeover switch C8. . In addition, in the above-described embodiment, the horn switch HS for blowing the horn (l) is configured so that it can also be used as a reverse switch, but the present invention is not limited to this, and it can also be used to turn on/off other electrical components. Even if the switch is configured so that it can be used as a back switch, I will not buy it.

"Effects of the Invention J As explained above, according to the present invention, there is provided an operation switch for supplying/cutting off power to a specific load, and a rotational force of the starter motor is transmitted to the drive wheels. If the rotation is reversed, press the operation switch n.
A switching means is provided to connect the operation switch and the starter motor so that the starter motor can be disconnected from a specific load and started/stopped by turning on/off the operation switch. The operation switch that turns the load on/off can also be used as a reversing switch to rotate the starting motor when reversing. This eliminates the need for a separate reversing switch and reduces the cost of the reversing device. It will be done. Additionally, in the past, when applying a reversing device to a motorcycle, there were many switches on the left handlebar, making it difficult to install a new reversing switch. Problems can be resolved.
