Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluid pressurized iAl for motorcycles.

In recent years, attempts have been made to install various fluid devices on motorcycles in order to improve their performance. For example, in order to improve the buffering function, there is an air suspension in which the filling amount of pressurized air is adjusted using a pressurized air supply source such as a compressor. Such an air suspension requires a compressor for the pressurized air Xi and a motor to drive the compressor, and these must be mounted on the motorcycle. However, since the mounting space of motorcycles is more limited than that of four-wheeled vehicles, there is a large demand for space as well as the demand for quantification.
It is said to be a big problem when mounting the above-mentioned fluid equipment.

Such problems are common not only to air suspension systems but also when other fluid devices, such as brakes for anti-skid systems, are mounted on motorcycles.

In view of the above-mentioned problems, an object of the present invention is to provide a 1-hour fluid pressurizing device for a motorcycle that can simultaneously perform @quantization and space control when a fluid device is mounted. It's about doing.

Production of a motorcycle according to the present invention that achieves the above objects
A fluid pressurizing device is characterized by connecting the input shaft of a compressor or pump for pressurizing the working fluid of fluid equipment mounted on a motorcycle to the output shaft of an engine's starter motor via a clutch. be.

(2) DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 1 shows a motorcycle equipped with an air suspension as a fluid device. A main frame 2 and a down tube 3 extend vertically and diagonally backward from a head pipe 1, and an engine 4 is mounted below the down tube 3. This engine 4 can be started by a starter motor 7. Furthermore, an air suspension 6 as shown in detail in FIG. 5 is provided between the rear end of the main frame 2 and the upper end of the rear arm 5.

The above-mentioned air suspension 6, as shown in FIG.
The main parts thereof include a cylinder 20, a piston 21 fitted into the cylinder 20 so as to be movable up and down, and a rod 22 connected to the piston 21. The cylinder 20 is filled with oil, and this oil flows through the hole provided in the piston 21 as the piston 21 moves up and down, and the flow resistance at this time generates a buffer force. ing. Further, a free piston 2 is provided below the cylinder 20.
3 is fitted into the lower cylinder 20, and the space within the lower cylinder 20 delimited by the free piston 23 is filled with inert gas.

On the other hand, a cylindrical case 24 connected to the rod 22 is fitted into the upper part of the cylinder 2D so as to be movable up and down. A rubber bellows 25 is provided between the inner wall of the case 24 and the outer wall of the cylinder 20, and an air chamber 26 is provided inside the bellows 25.
is formed. Air pressurized by a compressor 12, which will be described later, is pressurized into the air chamber 26 so that it functions as an air cushion. Further, a spring 2B is inserted between the lower end of the case 24 and a spring receiver 27 provided at the lower part of the cylinder 20. By changing the , the case 24 is moved up and down to expand and contract the entire case, and this operation increases the buffering force of the air cushion due to the air chamber 2 and the spring 2
It is now possible to adjust both the power and the power at the same time.

(3) Now, No. 2 IXi shows a sweeping system diagram for pumping the working fluid of the air suspension described above, and FIG. 3 is a schematic diagram showing the pressurizing device for the working fluid.

As shown in #3 @, the starter motor 7 has output shafts on both sides. A, 7b are provided, and one of the output shafts 7a is provided with a starter gear 8 having a built-in one-way clutch 9a, similar to a known device. It is adapted to drive the shaft 10. Therefore, by operating the starter motor 7, the output shaft 7a can start the engine 4 via the starter gear 8 and the gear 9. After the engine is started, the starter gear 8 is connected to the starter motor 7 side by the one-way clutch 8a. The rotation of the engine 4 is prevented from being transmitted to the engine.

On the other hand, the other output shaft 7 provided on the opposite side of the starter motor
A compressor 12 is connected to b via an electromagnetic clutch 11, and when the starter motor 7 is operated with the electromagnetic clutches 11 (5) (4) engaged,
The compressor 12 can now be turned off. In this case, the power system of the compressor 12 is turned back to the starter motor 7 side via gears 51 and 51 as shown in FIG. 4, and the compressor 12 and the starter motor 7 are installed side by side. Good too. With this configuration, the overall width of the device W
can be made smaller than in the case of the third @.

In FIG. 2, 16 is a vehicle height detector, which detects the vehicle height of the motorcycle. Since the vehicle height is proportional to the amount of expansion and contraction of the air suspension 6, the vehicle height detected by the vehicle height detector 16 is proportional to the expansion and contraction amount of the air suspension 6. The detection signal of this vehicle height detection t116 is outputted as a difference from the set reference height and inputted to the controller 17, and the control signal issued from this controller 17 is inputted to the starter motor 7, electromagnetic clutch 11, or solenoid valve 1B, respectively. It has become.

(6) On the other hand, the compressor 12, which is driven by the starter motor 7 through the electromagnetic clutch 11, sucks air from the atmosphere through the air filter 13, pressurizes this air, and pressurizes the air through the check valve 14. The air is supplied to the air suspension 6 via a dehumidifier 15. Further, a solenoid valve is provided in a branched manner in the dark path between the check valve 14 and the dehumidifier 15, so that pressurized air can be released through this solenoid valve.

When the vehicle height is different from a set reference height, the vehicle height detector 16 described above generates a signal corresponding to the difference from the reference height, and inputs the signal to the controller 17. Now, if the vehicle height is lower than the set reference height, that is, if the amount of extension of the air suspension 6 is shorter than the set reference length, the controller 17 will be For starter motor 7 and electromagnetic clutch 11! 1lij signal to operate these, while the solenoid valve 1st is set to 2nd V.
! Leave the valve closed as shown in fJ (7). Therefore, the starter motor causes the compressor 12 to move Ii! The air compressed by the compressor 12 is supplied to the air suspension 6, and the amount of expansion thereof increases. When the extension amount becomes 1 and the rod length, the difference from the reference length becomes zero, so the signal from the vehicle height detector 16 stops, and the air suspension 6 is maintained at the set reference extension amount.

Conversely, when the vehicle height is higher than the base*height, that is, when the amount of extension of the air suspension 6 is longer than the set reference length, the controller 17 outputs a control signal based on the positive difference signal from the vehicle height detector 15. Solenoid valve 1 and solenoid valve 1 are opened, and starter motor 6 and electromagnetic clutch 1 are opened.
Let 1 be t in the stopped state. However, the pressurized air in the air suspension 6 is released through the solenoid valve during the day, and when the amount of expansion is far from the standard length, the difference from the standard length becomes constant and the vehicle height detector 15 The signal stops. As this signal stops, the signal from the controller 17 also stops, so the solenoid valve 1 returns to its original closed state.
Air suspension (8) 3/6 is maintained at its set standard extension of 1.

According to the above-described device, the starter motor 7, which is idle except during the simulation, acts as a drive motor for the compressor 12, which is the source of pressurized air for the air suspension 6. Therefore, there is no need to provide a separate motor. In the past, the amount of motor that was not provided separately is reduced to txax, and the installation space is no longer required. In addition, since this starter motor can obtain a higher output than the motor that was conventionally provided independently for the compressor, it is possible to reduce the capacity of the pressure accumulator tank that was provided in the conventional device. Or it can be completely eliminated.

In addition, in the above-mentioned embodiment, as a clutch provided between the starter motor 7 and the compressor 12,! Although a magnetic latch 11 is provided, a one-way clutch (9) may be provided in place of the electromagnetic clutch 11. When such a one-way clutch is provided, the starter motor 7 is connected to the compressor 12.
When driving the compressor 1, it is necessary to rotate the engine 4 in the opposite direction from when it is started, and the one-way clutch must be connected to the compressor 1 when the starter motor is reversed.
It is necessary to make a tel that establishes a connection between 2 and 2. Furthermore, in the above embodiment, an electromagnetic clutch may be provided instead of the one-way clutch 8a built into the starter gear 8.

In addition, although the output shaft of the starter motor 7 was configured to be provided on both sides in the above-mentioned embodiment, it is configured to have only one on one side, and the starter gear and the compressor are connected to the output shaft on one side at the same time. It's okay.

Furthermore, although the above-mentioned embodiments have been explained in the case where the fluid equipment is an air suspension, the present invention is not limited to such air suspensions, but can also be applied to other fluid equipment (10) such as brakes of anti-skid systems. The oil pump in the anti-skid system brake can be operated by using the starter motor.
i! It is possible to move.

As described above, the working fluid pressurizing device for a motorcycle according to the present invention is a fluid device mounted on a motorcycle. Since the starter motor is connected via a clutch, the starter motor, which is idle at times other than when the engine is started, can be effectively used as a drive motor for the compressor or pump for the working fluid of fluid equipment, and it is not necessary to provide a separate motor. This eliminates the need for heavy lifting and reduces space for passengers on motorcycles.
