Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a damping force adjusting device for a motorcycle.

(Prior Art) Many proposals have been made by the applicant of the present invention regarding the idea of variably controlling the damping force of a front fork or a rear suspension of a two-wheeled vehicle in accordance with driving conditions.

The damping force is generally adjusted by changing the exciting force of the solenoid with a damping valve built in the front fork, etc., but the setting device (current controller) for adjusting this damping force is usually It is attached to the handle.

(Problems to be solved by the invention) However, since operation switches such as a light, a turn signal, a starter, and a horn are arranged near the grip of the handle, a setting device for adjusting the damping force is placed on the handle from the handle. It is quite difficult to place it near the grip that does not need to be separated in terms of space. Therefore, conventionally, a setting device was installed near the center of the steering wheel, but you have to take your hand off the steering wheel grip every time you adjust the damping force, not only the operability is bad, but there is also a problem from the viewpoint of running safety. there were.

The present invention aims to solve such a problem.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a damping force adjusting mechanism that changes a damping force of a front fork or a rear suspension according to a control current, and sets the control current value. In the damping force adjusting device for a two-wheeled vehicle including the damping force setting device, the setting device is an arc-shaped slide member that slides along the outer circumference of the handle pipe, and an operating lever integrally formed with the sliding member. The slide member is housed in a switch box provided at a base portion of a handle grip fixed to a handle pipe, and the operation lever is configured to project to the outside of the switch box.

(Operation) The operation lever is provided so as to project outside the switch box at the base of the grip and rotates along the outer circumference of the handle pipe, so that you can extend your thumb while operating the handle grip and operate it. Sometimes it does not interfere with other switches. Further, since the operation lever is independent of the handle grip and the handle grip itself does not rotate when setting the damping force, the rotation angle of the operation lever can be made relatively large and the adjustment gain becomes low. Furthermore, at this time, the sliding member of the damping force setting device is compactly housed in the switch box, and the operation lever is projected to the side surface of the switch box. Therefore, the length of the switch portion in the axial direction of the handle becomes short.

(Embodiment) In FIGS. 1 to 3, 1 is a handle body, and 2A and 2B are left and right grips. Switch boxes 4A and 4B in which various switches 3 such as lights, turn signals, starters, and horns are arranged are attached to the roots of the grips 2A and 2B. The grips 2A and 2B are fixed to the handle pipe 5.

The operation lever 7 of the damping force setting device 6 projects laterally from the end surface of the one switch box 4A.

The operation lever 7 rotates coaxially with the handle pipe 5, and as shown in detail in FIG. 3, is integrally formed with an arc-shaped slide member 8 that slides along the outer periphery of the handle pipe 5. It Inside the switch box 4A, the slide member 8 is guided by guide members 9A and 9B that also serve as stoppers, and rotates over a predetermined angle range. A rod 12 of a variable resistor 11 is connected to an end of the slide member 8 via a wire (flexible wire material) 10 guided by a guide member 9C. A detent mechanism 20 is provided for lightly positioning the slide member 8, and a ball 22 is pressed by a spring 21 to hold the operation lever 7 at an arbitrary position.

The variable resistor 11 is attached to the lower part of the switch box 4A, and the resistance value changes according to the expansion / contraction stroke of the rod 12. The control current to the damping force adjusting device 14 is controlled to increase or decrease via the control circuit 13 according to the resistance value, and the damping force generated by the front fork or the rear suspension is adjusted.

The variable resistor 11 has a built-in spring 15 as shown in FIG.
The rod 12 is automatically returned by the urging force of, but the resistance value is continuously changed by the resistor 16 and the brush 17 as described above, and a plurality of contact points are provided as shown in FIG.
16A, 16B, 16C, 16D are installed side by side in the stroke direction of the rod 12, and the brush 17 and the contacts are contacted in sequence according to the stroke position.
It is also possible to adopt a switch system in which 16A to 16D are in contact.

In this way, the L-shaped operating lever 7 is projected laterally from the end surface of the switch box 4A, and since the operating lever 7 rotates the turning of the handle pipe 5, the thumb grip 2A can be held while holding the handle grip 2A. It is possible to move the operation lever 7 by using, so that the damping force can be adjusted safely while traveling.

Various switches 3 are arranged in the switch boxes 4A and 4B, but the operating lever 7 projects laterally from the switch box 4A and rotates along the outer periphery of the handle pipe 5, so that the switch 3 and the operating lever 7 are There is no interference.

As described above, according to the present invention, the operating lever of the setting device is provided outside the switch box at the base of the handle grip,
Since this operating lever is configured to rotate along the outer circumference of the handle grip, the operating portion of the setting device can be arranged without interfering with other switches near the handle grip, and the handle can be operated by hand. You can operate the damping force setting device without releasing, and since the handle grip and the operating lever are independent, you do not accidentally operate the operating lever even if you grip the grip strongly to support the body. Operability and safety are improved.

In addition, since the handle grip itself does not rotate when setting the damping force, the rotation angle of the operating part can be adjusted to be relatively large compared to when the damping force is set by rotating the grip itself. Since the gain can be lowered, the damping force can be adjusted stably.

In addition, the sliding member of the damping force setting device can be compactly stored in the switch box, and the operating lever projects to the side of the switch box.Therefore, it is necessary to place something other than the switch box on the grip side. Without
The length of the switch part in the handle shaft direction can be shortened.
