The cap top is fastened and further, and one end of the second branch cable 6 is coupled to the oil pump. A cable lock nut is removed, the second branch cable 6 is set at a stay 7, a lock nut is fastened, and tuning of the oil pump is effected by regulating a play.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a split type throttle cable for transmitting the operation of a throttle grip to a carburetor and an oil pump.

[0002]

2. Description of the Related Art In motorcycles and the like, a throttle grip is turned to increase or decrease the engine speed. That is, the rotation of the throttle grip is transmitted to the valve of the carburetor via the throttle cable, and the rotation speed of the engine is changed by adjusting the opening of the valve.

On the other hand, it is necessary to change the amount of lubricating oil supplied to the engine according to the engine speed. For this reason, conventionally, when the throttle grip is turned, the rotation amount of the throttle grip is controlled by a carburetor valve via a single cable having one end connected to the throttle grip and a branch cable branched from the single cable. And the oil pump to operate the carburetor and oil pump at the same time.

[0004]

As described above, in order to transmit the amount of rotation of the throttle grip to the carburetor and the oil pump at the same time, one end of a branch cable is connected to the carburetor valve when the vehicle is assembled, and another branch cable is connected. One end of the cable is connected to the oil pump.

[0005] However, all connections must be made in a narrow place, and work is extremely difficult. In particular, the amount of oil supplied from the oil pump needs to be in accordance with the engine speed, so when connecting one end of the branch cable to the oil pump, adjust the oil play to adjust the cable play It must be made.

[0006]

According to the present invention, there is provided a first branch cable having one end connected to a carburetor and the other end connected to a connector, and a first branch cable having one end connected to an oil pump. A second end of which is connected to the connector
And a single cable having one end connected to the throttle grip and the other end connected to the connector, to form a split-type throttle cable. With such a configuration, the connection work in a narrow place and the tuning work of the oil pump can be omitted.

Preferably, the connector is housed in a cover. By being stored in the cover, the joint portion of the cable can be reliably prevented from coming off.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is an overall view of a split type throttle cable according to the present invention, and FIG. 2 is an exploded perspective view of a main part of the split type throttle cable.

The split-type throttle cable comprises a single cable 1 having one end connected to the throttle grip G side and a modularized portion 2. The modularized part 2 includes a first branch cable 4 having one end connected to a valve of the carburetor 3, a second branch cable 6 having one end connected to an oil pump 5, and a first branch cable 4 and a second branch. It is composed of a connector 8 to which the other end of the cable 6 is connected.
Reference numeral 7 denotes a stay that is not included in the modularized portion 2 but fixes the outer part of the branch cable 6.

The connector 8 is formed with a slit 8a slightly wider than the cable inner 1a of the single cable 1 and a concave portion 8b into which the distal end 1b of the cable inner 1a fits, and the cable inner 1a is inserted through the slit 8a. The single cable 1 is connected to the first branch cable 4 and the second branch cable 6 by inserting the cable 1 into the connector 8, pulling the cable inner 1a, and fitting the distal end 1b into the recess 8b. The structure of the connector is not limited to the one described above, but may be any as long as the first and second branch cables 4 and 6 and the single cable 1 can be connected with one touch.

A cover 9 is attached to the connecting portion. Although the cover 9 is not always necessary, the connection between the first and second branch cables 4 and 6 and the single cable 1 can be reliably prevented by covering the connecting portion with the cover 9.

To assemble the modularized part 2 with the carburetor 3 and the oil pump 5 mounted on the engine,
First, a first branch cable 4 and a second branch cable 6 whose other ends are connected to the connector 8 are prepared in advance. And
First, the cap top of the carburetor 3 is removed, the carburetor valve is taken out, one end of the first branch cable 4 is connected to the carburetor valve, and the cap top is tightened.

Further, one end of the second branch cable 6 is connected to an oil pump, and a cable lock nut is removed.
The second branch cable 6 is set on the stay 7, and the lock nut is tightened to adjust the play to synchronize the oil pump.

When the modularization is completed in this way, the engine with the modularized portion 2 of the throttle cable assembled is mounted on the body frame. At this time, the connection between the first branch cable 4 and the carburetor valve, the connection between the second branch cable 6 and the oil pump,
Further, the tuning operation of the oil pump has been completed, and the actual operation is only the connection between the single cable 1 and the connector 8 and the attachment of the cover 9.

[0015]

According to the present invention as described above,
A first branch cable, one end of which is connected to the carburetor and the other end is connected to the connector, and one end which is connected to the oil pump side, and a cable for simultaneously transmitting the amount of rotation of the throttle grip to the carburetor and the oil pump. Are composed of a second branch cable connected to the connector, and a single cable connected at one end to the throttle grip and connected at the other end to the connector. Connection work and tuning operation of the oil pump can be omitted.

Although the number of man-hours for the operation is the same as the conventional one,
The total time required for modularization is 22 seconds, and when connecting the branch cable to the carburetor and oil pump already mounted on the vehicle body, it takes much longer to assemble than it took 35 seconds in total. The time has been reduced.
