Description

  The present invention relates to a throttle operating device for a motorcycle.

  Patent Document 1 discloses an operation device for a shift lever of a vehicle, and its outline will be described with reference to FIG. FIG. 4 shows a cross-sectional plan view of the chucking portion of the shift lever operating device, and the rectangular main body 2 is rotatably supported on the end of a support rod 1 connected to an actuator (not shown). Then, one end of a pair of operating rods 3 is supported on the main body 2 via a pin 4 so as to be rotatable. A semicircular claw 5 is provided opposite to the other end of the operation rod 3. Each claw 5 has a shaft pin 5 a at the center on the outer peripheral side, and the shaft pin 5 a is rotatably supported in the hole 3 a of the operation rod 3.

  Further, a protruding spring locking portion 6 is provided on the inner surface side near the pin 4 side end portion of each operation rod 3, and a concave portion 7a is also provided in the support portion 7 installed in the central portion of the main body portion 2. A compression coil spring 8 is provided between the spring locking portion 6 and the recess 7a. As a result, the operating rods 3 are urged to rotate in the direction of opening to each other, that is, in the directions of arrows A and B. Each operation rod 3 is operated by a drive source of the actuator unit. One end of a flexible tubular outer wire 9 is attached to one operation rod 3, and the end of the inner wire 10 inserted into the outer wire 9 is connected to the other operation rod. It connects with the attaching part 11 provided in 3. FIG.

  Next, the operation of the above configuration will be described. First, when the inner wire 10 is driven to be pulled into the outer wire 9 by the drive source of the actuator unit, the pair of operation rods 3 are rotated in a direction approaching each other, and the vehicle shift lever is placed between the semicircular arc-shaped claws 5. 12 is pinched. In this state, the support rod 1 is driven by the actuator portion, and the shift lever 12 is shifted. At this time, the tilt state of the shift lever 12 changes depending on each position of the shift operation. This change in tilt is absorbed by the main body 2 rotating around the X axis with respect to the support rod 1. Next, the support rod 1 is similarly driven, and the shift lever 12 is selected. The change in the inclination of the shift lever 12 during the selection operation is absorbed by the shaft pin 5a of the claw 5 rotating about the Y axis in the figure with respect to the operating rod 3. Therefore, good operability can be obtained corresponding to any inclination of the shift lever 12.

  On the other hand, in a running test apparatus for a motorcycle, the throttle is operated by an actuator. FIGS. 5 (a) and 5 (b) are a front view and a perspective view of a main part of a throttle operating device for a two-wheeled vehicle. A recess 13c is formed on the upper surface of the base portion 13a, and a female screw portion 13d is formed on the base portion 13a. Reference numeral 14 denotes an upper plate having a recess 14a on the lower surface and an insertion hole 14b penetrating vertically. Reference numeral 15 denotes a tightening screw composed of a male screw portion 15a and a handle portion 15b. The throttle grip 16 of the two-wheeled vehicle is sandwiched between the concave portion 13c of the base portion 13a of the lower plate 13 and the concave portion 14a of the upper plate 14, and the male screw of the tightening screw 15 The throttle grip 16, the lower plate 13, and the upper plate 14 are integrated by inserting the portion 15 a through the insertion hole 14 b of the upper plate 14 and screwing and tightening the female screw portion 13 d of the base portion 13 a of the lower plate 13.

The throttle grip 16 is rotatably supported by the handle grip of the two-wheeled vehicle, and is linked to the engine throttle valve via a throttle wire. A ring-shaped connecting portion 17 is attached to the upper portion of the upper plate 14, and an actuator is connected to the connecting portion 17 via a wire 18. Then, by operating the wire 18 as indicated by an arrow 19 by an actuator, the throttle grip 16 is rotated in both directions as indicated by an arrow 20 to perform an engine throttle operation.

  The above-described conventional two-wheeled vehicle throttle operation device includes the lower plate 13, the upper plate 14, and the tightening screw 15. The mass increases, the inertia is expensive, and the attachment work to the throttle grip 16 is easy. It was not. In addition, the mounting space was increased, causing interference with the surroundings.

  The present invention has been made to solve the above-described problems, and has a light weight, low inertia and low cost, is easy to mount on the throttle grip, has a small mounting space, and is free from surroundings. It is an object of the present invention to obtain a two-wheeled vehicle throttle operating device that does not cause interference.

  According to a first aspect of the present invention, there is provided a motorcycle throttle operating device comprising: a first pressing member having a large friction surface formed on one surface and belt through holes formed at both ends; Is formed with a large pressing surface, belt pressing holes formed at both ends, a second pressing member, one end connected to the first and second belt buckles, and the other end connected to the second pressing member. Folded through the belt through hole of the member and passed through the circumferential surface of the throttle grip of the motorcycle, folded back through the belt through hole of the first pressing member and fastened to the first and second belt buckles. The first and second belts that contact the throttle grip with the friction surface of the pressing member 2 is connected to one of the pressing members via a wire to rotate the throttle grip. Those equipped with an actuator for.

  As described above, according to the present invention, the throttle operating device is configured by the first and second pressing members, the first and second belts, the first and second belt buckles, and the mass is light. Low inertia, low cost, and easy attachment to the throttle grip. Also, the installation space is reduced, and interference with the surroundings is less likely to occur.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a main part of a throttle operating device for a motorcycle according to the best mode for carrying out the invention. In FIG. 1, an uneven surface 21a is formed on one surface as shown in FIGS. 2 (a) and 2 (b). The first pressing member is provided with first and second belt through holes 21 b and 21 c at both ends thereof, and a connecting portion 21 d is provided on the other surface of the first pressing member 21. Reference numeral 26 denotes a second pressing member having an uneven surface 26a formed on one surface as shown in FIGS. 3 (a) and 3 (b), and first and second belt through holes 26b, 26c is formed. Reference numerals 22 and 23 denote first and second nylon belts, one end of which is connected to the first and second belt buckles 24 and 25, and the other end of the second pressing member 26.
