DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a parking device for a motorcycle in which a main stand is raised by a motor.

Prior art and its problems In motorcycles with large engine displacements, even if lightweight materials such as aluminum alloy are used for the body components, the vehicle weight is still large and it is difficult to operate the stand up. Even if it wasn't that big, women found it difficult to operate the stand.

To solve this problem, there is a system that uses a motor to raise the main stand and lift the rear wheels, but such a system requires a large torque to raise the main stand, and the motor capacity is low. had no choice but to grow.

In particular, if the starter motor is also used as the motor for the above-mentioned stand raising operation, the capacity of the motor for starting the engine will be unnecessarily large, which is extremely disadvantageous in terms of installation space for the starter motor or vehicle production costs. It is.

Means for Solving the Problems The present invention relates to an improvement of a stand device for a motorcycle that overcomes the above-mentioned difficulties, and its purpose is to be able to raise a main stand with a relatively small motor, and to An object of the present invention is to provide a parking device for a motorcycle that can further stabilize a parking posture with a main stand erect.

5. It is connected to a main stand 35 (having a stand roller 36 at the tip) via a one-way torque transmission device 22, a drive link arm 28, a stand link 30, and a turnbuckle 31, and the starter motor 13 controls the starting rotation of the engine 11. When the main stand 35 rotates in the opposite direction, the power of the motor 13 is decelerated and boosted, and the main stand 35 swings toward the front of the vehicle body around the stand bolt 34 and stands upright.

Therefore, as shown in FIGS. 6 and 8, the stand raising reduction gear 15 disposed on the right side of the vehicle body 1
4, and a second worm shaft 1 that is pivoted perpendicularly to the starter motor rotation shaft 14.
The first worm 1 is engaged with the spline at 8.
a first worm gear 17 that meshes with the second worm shaft 18; and a second worm 19 that is integrally formed with the second worm shaft 18.
, a second worm gear 20 that meshes with the second worm 19 , and a reduction gear casing 21 .

The one-way torque transmission device 22 also includes a drive link shaft 27 that is rotatably supported by the reduction gear casing 21, and a screw spline 23 that rotatably fits into the drive link shaft 27 (the screw spline 23 includes the a second worm gear 20), a drive side latch 24 that meshes with the screw spline 23, and a driven ratchet that is fitted integrally with the drive link shaft 27 and meshes with the drive side latch 24. 25, and when the starter motor 13 rotates in the direction of raising the stand, the drive side ratchet 24
moves toward the driven ratchet 25 and meshes with the driven ratchet 25, so that the stand raising torque of the starter motor 13 is transmitted to the drive link shaft 27. Note that an engagement groove 26 is formed on the outer periphery of the driven ratchet 25.

Further, a drive link arm 28 is integrally fitted to the drive link shaft 27, a stand link 30 is attached to the tip of the drive link arm 28 via a pin 29, and the stand link 30 and the main stand 35 are connected to each other by a turnbuckle. 31 and a pin 32, and as shown in FIGS. 4 and 5, when the drive link shaft 27 rotates clockwise or counterclockwise, the main stand 35 is in an inverted position (storage position) or in an upright position ( parking position).

Furthermore, the main stand 35 is rotatably supported by a stand bolt 34 that passes through a stand support tube 33 that is integrated with the vehicle body 1, and is attached with a nut 37. The stand 35 can be erected while the wheels remain on the ground.

Further, a pawl shaft 38 is rotatably mounted in the reduction gear casing 21, and a pawl shaft 38 is rotatably attached to the driven ratchet 21.
A parking pole 39 and a parking pole arm 40 that can be releasably engaged with the engagement groove 26 of No. 5 are integrally provided on the pole shaft 38, and one end of a lever wire 41 is tied to the tip of the parking pole arm 40. A coil spring (not shown) is fitted onto the pawl shaft 38 to urge the parking pawl 39 to engage with the engagement groove 26 .

Next, to explain the left side of the vehicle body 1 (see FIGS. 2 and 3), the tip of the rear brake wire (traction means) 42 is tied to the rear brake lever 43, but there is a An engaging piece 44 that engages with the movable arm member 50 is integrally fitted.

Also, on the left side of the main stand 35, there is a pin 4.
a spring retaining ring 46 with an oblong guide opening 47 which is protruding from the pin 45 and can be engaged with the pin 45;
is swingably supported by the vehicle body 1 via a pin 49, and a spring retainer 48 is formed in the spring retaining link 46.

Further, a swinging arm member 50 is tiltably supported coaxially with the pin 49, and a spring receiver 51 is also formed on the swinging arm member 50, so that the spring receiver 48 of the spring retaining link 46 and the swinging arm member 50 are connected to each other. A brake coil spring 52 is interposed between the spring receiver 51 and the spring 5
A preset bolt 53 is interposed to apply a presetting force to the second part and maintain a constant interval.
As shown in the figure, when the main stand 35 is in an upright state, the hook-shaped portion of the swinging arm member 50 is attached to the engaging portion 4.
4.

On the right side of the vehicle body, a starter motor stop switch protrusion 54 is provided integrally with the drive link arm 28, and when the main stand 35 is upright, the starter motor stop switch 55 is activated by the protrusion 54.
The switch 55 is operated in contact with the switch 55.

Note that 56 is a holding piece for the rear brake wire 42.

Since the illustrated embodiment is configured as described above, when the main stand 35 is tilted toward the rear of the vehicle body (storage state), the main stand 35
5, when the parking lever 9 is swung forward, the stand raising switch (not shown) is closed, the starter motor 13 is rotated in the opposite direction to the engine starting direction, and the wire is 41 is delivered to the rear of the vehicle.

Then, as the starter motor 13 rotates in the opposite direction, the second worm gear 20 of the stand erecting reduction gear 15 rotates while being decelerated, and the drive side ratchet 24 approaches and engages with the driven ratchet 25, causing the drive link shaft 27 to rotate. , is rotated counterclockwise in FIG.

This rotation of the drive link shaft 27 causes the drive link arm 28 to swing in the same direction, and the pin 29, stand link 30, turnbuckle 31
The main stand 35 is vertically erected around the stand bolt 34 via the pin 32, the starter motor stop switch protrusion 54 comes into contact with the movable piece of the starter motor stop switch 55, and the switch 55 is operated. The cell motor 13 is
A control circuit (not shown) reverses the rotation direction (engine starting rotation direction) for several seconds, disengages the ratchets 24 and 25 of the one-way torque transmission device 22, and stops the starter motor 13.

In this way, when the main stand 35 is in the upright position, the lever wire 41 is extended rearward, so that the parking pole arm 40 and the parking pole 30 are moved as shown in FIGS. 4 and 5 by the spring force of the coil spring (not shown). Even when the main stand 35 is swung clockwise in FIG. 8, the parking ball 39 engages with the engagement groove 26 of the driven latch 25, and the one-way torque transmission device 22 is unlocked, the main stand 35 remains on the vehicle body. It will not fall backwards.

Also, when the main stand 35 stands up, the third
As shown in the figure, the holder link pin 45 also moves clockwise together with the stand 35, and in conjunction with this, the spring retaining link 46 swings clockwise about the pin 49, causing the swinging arm member 5
0 also follows this and swings in the same direction, and the engaging piece 4
4.

Therefore, even if the tip of the rear brake wire 42 is not pulled forward, the swing arm member 50 engages with the engagement piece 44 and the engagement piece 44 is pulled forward, and the rear brake lever 43 swings, and the parking brake is applied to the rear wheels 12.

Even if the position of the engaging piece 44 is located further to the rear of the vehicle body than the normal position, the positional error is absorbed by the compressive deformation of the brake coil spring 52, and the parking brake is activated with the main stand 35 upright. Can be applied reliably.

Furthermore, even if the main stand 35 is being raised, the weight of the vehicle is large, or the starter motor 13 is
Even if the main stand 35 stops due to insufficient charge in the power supply battery (not shown), both ratchets 24 and 25 of the one-way torque transmission device 22 will mesh, and the main stand 35 will remain horizontal. Since the main stand 35 is stopped without returning to its original position, it is possible to take down objects mounted on the vehicle body, restart the starter motor 13, or raise the main stand 35 manually.

Further, when the main stand 35 is in the upright position, the latches 24 and 25 of the one-way torque transmission device 22 are disengaged due to a certain amount of idle rotation of the starter motor 13, so that the parking pole arm 4
By swinging the main stand 35 forward, the parking pole 39 can be disengaged from the engagement groove 26 of the driven ratchet 25, and the main stand 35 can be swung toward the rear of the vehicle body to take the stowed position and the vehicle can be driven. I can do it.

Furthermore, as the main stand 35 rises, the swinging arm member 50 swings clockwise in FIG. 2 and engages with the engagement piece 44 as shown in FIG. The engaging piece 44 is pulled toward the front of the vehicle body, and the rear brake lever 43 swings to apply the parking brake to the rear wheel 12, so even if a forward force is applied to the vehicle body, the vehicle body will not move. A large force due to a force in the forward direction of the vehicle body does not act between the engagement groove 26 of the driven ratchet 25 and the parking pawl 39.

In the embodiment described above, the engagement groove 26 was formed in the driven latch 25 and the parking pawl 39 that engaged with the engagement groove 26 was formed. It's okay.

Furthermore, in the embodiment described above, the raising operation of the main stand 34 and the operation of the stand brake arm 50 in conjunction with this are performed by reversing the starter motor 13. The operation may be performed using a motor, or a motor for the operation may be separately installed.

Effects of the Invention In the present invention, as described above, the dimensions of the main stand are set so that the main stand can be erected with the front and rear wheels kept on the ground. The torque for standing up may be small, and a small capacity motor can be used.

Furthermore, in the present invention, since the raising operation of the main stand is linked to the parking brake operation of at least one of the front and rear wheels, the vehicle body does not move even when a forward force is applied to the vehicle body.
Parking is possible in stable conditions.
