DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running stabilizing device for a motorcycle with a sidecar, and more particularly to a running stabilizing device for a motorcycle with a sidecar having improved running stability when an occupant is not on the sidecar.

[0002]

2. Description of the Related Art Conventionally, a motorcycle with a sidecar having a sidecar attached to a motorcycle has been widely used in various countries as well as in Japan.

[0003] Such a motorcycle with a sidecar is more difficult to balance on a curve or the like than a general motorcycle, and requires a high degree of driving technology.

[0004] In particular, the position of the center of gravity of the entire vehicle changes greatly between when the occupant is not in the vehicle and when the vehicle is not in use. Difficult.

[0005] Such a motorcycle with a sidecar is disclosed in, for example, Japanese Patent Publication No. 32-3526 and Japanese Patent Publication No. 32-75.
A stabilizing device with improved running stability when traveling on a rough road is proposed in, for example, Japanese Patent Application Laid-Open No. 64 (1999).

[0006]

However, all of these methods only improve the connection between the two-wheeled vehicle and the sidecar, and fundamentally solve the problem caused by the shift of the position of the center of gravity between when the vehicle is on the sidecar and when the vehicle is empty. It does not eliminate it.

The problem to be solved by the present invention is to solve the problem associated with the shift of the center of gravity between when the sidecar is occupied and when the sidecar is empty, with a relatively simple structure. Another object of the present invention is to provide a travel stabilizing device capable of traveling at high speed.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a running stabilizer for a motorcycle with a side car according to the present invention comprises a motorcycle and a side car attached to the motorcycle by a connecting member, and the side car has a weight adjustment. And a liquid tank for the

Here, the liquid tank can be provided in various shapes at the lower portion and both sides of the sidecar, and the seat of the sidecar can be formed hollow. Furthermore, it can be molded as an integral part when manufacturing the sidecar.

The most common liquid to be injected is water that is easily available and harmless even when discharged. However, by using a liquid having a high specific gravity, the volume of the liquid tank can be reduced. can do.

[0011]

In the running stabilizing device for a motorcycle with a sidecar according to the present invention, when the occupant is in the sidecar, the vehicle runs with the liquid tank empty, and when the occupant is empty, the liquid tank corresponds to the weight of the occupant. By injecting the liquid, it is possible to drive the vehicle at the same center of gravity as when the vehicle is ridden even when the vehicle is idle.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the embodiments shown in the drawings.

FIG. 1 is a plan view of a motorcycle with a sidecar provided with the stabilizer of the present embodiment, and FIG. 2 is a side view of FIG.

In the figure, reference numeral 1 denotes a motorcycle (motorcycle), which is provided by two connecting members 1a provided before and after the motorcycle 1.
A sidecar 2 is attached.

Reference numeral 3 denotes a liquid tank which also serves as a seat of the sidecar 2. As shown in the perspective view of FIG. 3, the inside of the tank has a hollow shape capable of injecting 60 to 70 liters of liquid, and a liquid such as water is injected into the upper part. The inlet 4 is provided at the lower portion with an outlet 5 for discharging the internal liquid. Reference numeral 6 denotes a meter indicating the amount of liquid injected therein, which indicates the weight according to the type of liquid. 7 is an air inlet for facilitating the discharge of the liquid.

FIG. 4 is a perspective view of the separator 8 provided in the liquid tank 3, which comprises a vertical plate 8a and a horizontal plate 8b which are perpendicular to each other.
A semicircular water passage 8c is provided at the lower part of b. Thereby, the liquid is filled into the entire liquid tank 3 from the water passage hole 8c at the time of injection, while the vertical plate 8a and the horizontal plate 8b serve as partition walls at the time of curve running, thereby preventing movement of the liquid inside and improving running stability. Can be done.

In the above configuration, when traveling with the occupant on the sidecar 2, the liquid tank 3 is emptied, and when the occupant is not on the sidecar 2, a liquid such as water substantially corresponding to the weight of the occupant is used. From the inlet 4 into the liquid tank 3. This injection can be easily performed from a water hose at a gas station or the like. At this time, for example, if the weight of the occupant of the sidecar 2 is 65 kg, by injecting 65 liters of water, it is possible to travel with the same sense of balance as when riding when the sidecar 2 is empty. Further, when the liquid inside the liquid tank 3 becomes unnecessary, for example, when riding, the liquid can be easily discharged by opening the discharge port 5 provided at the lower part of the liquid tank 3 so that the inside of the liquid tank 3 is empty. Can be.

As described above, the running stabilizer of the present embodiment is
With a relatively simple structure, it is possible to always stabilize the position of the center of gravity irrespective of the presence or absence of riding in the sidecar 2 only by taking the liquid in and out of the liquid tank 3. Further, the liquid tank 3 itself also functions as a bumper for protecting the occupant.

FIG. 5 is a plan view of a motorcycle with a sidecar according to another embodiment, FIG. 6 is a rear view of the motorcycle, and FIG. 7 is a perspective view of a liquid tank provided in the motorcycle with a sidecar shown in FIGS.
In the following embodiments, the same components as those in the embodiment shown in FIG.

The liquid tank 11 of this embodiment includes a first tank 11a and a second tank 11b provided on both sides of the sidecar 2, respectively.
They are connected by a pipe 12. Such a structure also serves as a bumper to protect the occupants' safety.

FIG. 8 is a plan view of a motorcycle with a sidecar according to another embodiment, FIG. 9 is a rear view thereof, and FIG. 10 is a perspective view of a liquid tank provided in FIGS.

The liquid tank 15 of this embodiment is provided at the bottom of the sidecar 2. With such a structure, the position of the center of gravity can be lowered, and the running stability can be further improved. .

In each of the above-mentioned embodiments, by connecting a dedicated hose to the outlet 5 and applying pressure to the liquid tank, it can be used as water for fire extinguishing in an emergency. It can also be used for water transport or as an emergency gasoline reserve tank. Further, by piping a part of heat transfer or exhaust gas (muffler) in the liquid tanks 3, 11, and 15, it can be used as a heater.

[0024]

As described above, the running stabilizer for a motorcycle with a sidecar according to the present invention has a liquid tank for adjusting the weight of the sidecar. Therefore, by filling the liquid tank with the liquid corresponding to the weight of the occupant when the sidecar is empty, it is possible to secure the same center of gravity position as when riding, and to improve the running stability especially on rough roads and curved roads. Can be. As a result, fatigue of the driver of the motorcycle with the sidecar during long-distance running can be reduced.
