Abstract

PURPOSE:To facilitate the take-out and parking of a motor-cycle, by coupling the output shaft of a bidirectionally rotatable motor to both means always coupled with an axile to be rotated and a step-drive actuator, through speed change and transmission means. CONSTITUTION:Upon normal running of a motor-cycle the torque of an engine is transmitted to a sprokcet 8 through the input and output shafts 5, 7 of a speed change unit 4, and is transmitted to the axle through a chain 11. Meanwhile, upon neutral operation of the transmission unit, wheh a gear 24 is meshed with a gear 25 while a gear 27 is disengaged from a gear 29 by operating levers 26, 31, and when a motor 20 is rotated, the axle alone rotates. Accordingly, the axle may be rotated at a slow speed by suitably setting the products of speed change rates of parts. Further, upon stopping of a motor cycle, when the gear 24 is disengaged from the gear 25 while the gear 27 is meshed with the gear 29, and when a motor part 21 is rotated, a stand may be set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an auxiliary operation device for a motorcycle, and more particularly to an auxiliary operation device for moving a motorcycle at very low speed.

[Prior art]

Conventionally, the drive system of a motorcycle has been configured as shown in FIG.

That is, a clutch 2 is provided for the output sum rK of the engine 1, and a gear 3 is provided on the non-drive side of the clutch 2.

This gear 3 is a gear 6 attached to the input shaft 5 of the transmission 4.
On the other hand, the output shaft 7 of the transmission 4 has several sedge rockets 8.

This sedge rocket 8 is operatively connected by a chain 11 to a sedge rocket 10 provided on a car 114119.

In general, the drive system of a motorcycle is configured in an upwardly inclined manner, but such a drive system allows the motorcycle not only to move backward, but also to move forward, for example, at a speed of 0.1 m/
It was not possible to take him away at the extremely slow speed of 1.2 seconds. For this reason, it is extremely difficult to move a large motorcycle, especially one with a heavy weight, into a narrow space such as a garage, or to carry it out, as the operator must move it by his or her own power. there were.

Additionally, when parking a large vehicle, it required a great deal of human effort to raise the stand and lift the rear wheels. For the latter, an example is JP-A-57-1.
30877 and Japanese Patent Laid-Open No. 57-138476, methods have been proposed for raising the entire stand using a motor, but none of these methods have been put to practical use at present. This is thought to be due to the low cost/foreignness of the system, as only the stand erecting has been mechanized, and the installation of cars in designated positions on the reeds for parking still requires manual labor.

[Summary of the invention]

The purpose of the present invention is to comprehensively reduce the amount of manpower required for carrying in/out, parking, etc. of motorcycles, and also to share the power source used at that time, thereby making it even more advantageous in terms of cost. An object of the present invention is to provide an auxiliary guide device for a motorcycle that is extremely cost-effective, safe, and simple.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the auxiliary operation system for a motorcycle according to the present invention will be explained in detail with reference to preferred embodiments shown in the accompanying drawings.

FIG. 2 shows an auxiliary operating system for a motorcycle according to an embodiment of the present invention. This embodiment is shown in Fig. 2, which shows the drive system of the conventional motorcycle shown in Fig. 1.
! : Constituent parts and [bl- or corresponding parts will be referred to with the same reference numerals and explained] will be omitted.

The auxiliary entrainment device f7 of the motorcycle of this embodiment is an electric motor 20 operatively connected to the transmission 4 and capable of rotating in reverse.
including.

By the way, the transmission 4 has an output shaft 7 as shown in FIG.
A plurality of gears 12 each having a different number of gears for shifting are provided in the
．． It is equipped with 13, 14, 15, and 16. Among these gears, the gear 16 is not used for speed change, but is used for slow speed operation on the output shaft 7.
It was set up in Niyamata.

The electric motor 20 includes an electric motor section 21. which rotates once when supplied with electric power. The planetary reducer section 22 is operatively connected to a shaft rotated by the electric motor section 21, and an output shaft 23 is connected to an output gear of the planetary reducer section 22. This output shaft 23 carries a gear 24 which is restrained in the rotational direction and movable in the axial direction.
4 meshes with the gear 16 which is connected to the output shaft 7 of the transmission 4 through the idle gear 25.

A gear 2 slidably supported on an output shaft 23 of an electric motor 20
Reference numeral 4 has an awn that engages with one end of a lever 26 that is pivotally mounted on the machine frame of the electric motor, and the other end of the lever 26 projects outside the machine frame as an operating rod. As a result, the gear 24 is engaged with or disengaged from the idle gear 25 by operating the lever 26. .

Furthermore, another gear 27 is carried on the output shaft 23 of the electric motor 20. Like the gear 24 described above, this gear 27 is also restrained in the rotational direction of the output ηl+23, but is slightly offset so that it can slide in the axial direction. A gear 29 supported by a shaft 28 is disposed in the motor frame at a position where the gear 27 meshes with the output shaft 23 by sliding.

A shaft 28 that fixedly supports this gear 29 is an actuator x-tire that raises a step (not shown) of a motorcycle.
It is connected to a flexible shaft 30 that transmits C' IMI & force t'. In addition, gear 27 and gear 29
In order to engage or disengage with the
A lever 31 similar to the lever 26 described above is pivotally mounted on the machine frame, and has a protruding apex that engages with a boss portion of the machine frame, and a lever 31 that is similar to the lever 26 and has the other end protruding from the machine frame.

According to the auxiliary operation system for a motorcycle configured as described above, for example, when the motorcycle is running normally, the engine l
Due to the engagement of clutch 2, the rotational force of gear 3. gear 6
, is transmitted to the suji rocket 8 via the input shaft 5 of the transmission 4 and the output @77il-, and is transmitted to the axle 9 by the chain 11.
It will be communicated to you. At that time, the driver may use the transmission 4 as necessary.
A transmission mechanism including gears 12 to 15 located between an input shaft 5 and an output shaft 7 is selected, and the rotational force of the engine 1 is transmitted to the axle 9 to carry out operations from starting to high-speed running.

Here, two positive stages are normally used to stop the Vcm shaft 9 when the engine 1 is rotating. That is, one is to disengage the clutch 2, and the other is to set the transmission 4 to the neutral position. Generally, neutral is selected except for short-term stops. Now, when the transmission 4 is in the neutral state, the gear 24 is engaged with the gear 25 as shown in FIG. Only the axle 9 is driven without any rotational force being transmitted. Therefore, the reducer section 22, gear 24, gear 16 and sprocket 8.10 of the electric motor 20
By appropriately determining the speed change ratio of each of the
9 can be rotated very slowly. It's a reed.
Since the direction of rotation of the electric motor section 210 of the electric motor 20 can be easily changed to the left or right, the motorcycle can be driven forward or backward by rotating the axle 9 left and right.

Note that the left and right rotation of the motor section 21 can generally be easily achieved by switching the positive and negative input voltages.

Next, when the motorcycle stops at a predetermined position, the levers 26 and 31 are fully operated to disengage the gears 24 and 25, fully engage the gears 27 and 29, and move the electric motor 21 to the Rotate in a fixed direction.

As a result, the rotational force is transferred to the reducer section 22 and the gear 27.
．． At 29, the speed is reduced, and the flexible shaft 30 transmits the signal to an actuator that raises the stand (not shown), and as a result, the stand is set. Tonosu)
In order to remove the handle, the electric motor section 21 may be rotated in the opposite direction to the direction described above. It goes without saying that during normal running of the motorcycle, the gear 24 and the idle gear 25 are disengaged by the Leno (-26) to cut off the rotational force from the engine 1.

Generally, the battery installed in the vehicle is used as the input for driving the electric motor 20, but if the electric power stored in the battery is low and insufficient to drive the electric motor 20, the engine 1 -1: It can also be used by rotating the axle 9 and the operating speed of the stand erecting actuator, as shown in the figure. Gear 24.
25 and gears 27 and 29 or all the reduction gears of the reduction gear unit 22, or it is optional to add a transmission mechanism.

Furthermore, the same effect can be obtained even if the rotational force of the electric motor 20 is directly transmitted to the chain 11 or the axle 9 by providing a necessary transmission mechanism. Furthermore, it is clear that if the levers 26 and 31 are driven indirectly by actuators such as electric switches, the operation will be further facilitated and automated, making it more convenient for the operator.

In place of the gear 16, a conventionally known gear which is at the output ff11+7 and meshes with the output shaft 7 when in neutral can be used. In the invention, the output shaft of an electric motor that can rotate left and right in a motorcycle is set to H [a constant deceleration rate of 4].
The step drive of the vehicle is connected to the vehicle or wheelchair 11 through a first transmission means that is always connected to the vehicle or wheelchair 11 for rotation, and the second transmission means that has a predetermined deceleration rate from the output shaft. Since it is connected to an actuator, it is possible to move the motorcycle forward and backward at very low speeds without using engine power, and also to park the vehicle! lll
Therefore, it is possible to provide an excellent auxiliary operation device for a motorcycle that is economical, safe, and easy to fully operate the motorcycle.
