Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the operation mechanism of an electric transmission.
In particular, the present invention relates to an operating mechanism for an electric transmission that improves the operability of the transmission and prevents malfunctions by shifting the gear by sliding the handlebar grip of a motorcycle in the axial direction while grasping the handle grip.

[Prior Art] The operating mechanism of a transmission in a motorcycle includes:
There are two types: a foot-operated type and a manual type. In the foot-operated type, the clutch lever is gripped with the left hand and the change pedal is depressed with the left or right foot to change the clutch. The manual type will be described later. In addition, there are two types of change mechanisms: a selective type and a rotary type. In the selective type, the order in which the pedals are pressed is different. For example, you step down to the 1st gear position, conversely, pull it up to the neutral position, and then pull it up again to the 2nd gear position.
speed and final speed position. In the rotary type, by depressing, the gear can be changed from the neutral position to the first speed position, second speed position, and final speed position, and by further depressing, the speed can be changed to the neutral position.

These methods adjust the speed of the motorcycle by changing the rotational speed ratio between the input shaft and the output shaft.

[Problems to be Solved by the Invention] By the way, among conventional motorcycle transmission operating mechanisms, there is a manual type as shown in FIGS. 7 to 9.

However, as shown in FIG.
Upshift/downshift operation section 102
In the case where a shift operation is performed, it is necessary to put a finger on the operating section 102 in advance, and the overall shift operation time is disadvantageously long.

Furthermore, as shown in FIGS. 8 and 9, there is also one in which a handle switch box 104 is provided with an operating lever 106. However, when operating this operating lever 106, it is necessary to remove the thumb from the handle grip 4, and as mentioned above, there is the disadvantage that the shift operation takes a long time.

[Purpose of the invention] Therefore, in order to eliminate the above-mentioned disadvantages, the purpose of this invention is to attach a movable part consisting of a handle grip and a clutch lever to a fixed part consisting of a handlebar so as to be able to slide in the axial direction. It is an object of the present invention to provide an operation mechanism for an electric transmission that can perform speed change by sliding the movable part in the axial direction, improve operability, simplify the operation, and prevent erroneous operation.

[Means for solving the problem] In order to achieve this object, this invention forms a movable part by a handle grip and a clutch lever in an electric transmission having a manual operation mechanism, and also includes a handlebar grip and a clutch lever. Therefore, a fixed part is formed, and the movable part is mounted so as to be slidable in the axial direction with respect to the fixed part in order to change gears by sliding the movable part in the axial direction.

[Function] With the above-described structure, when riding the motorcycle, the movable part consisting of the handle grip and clutch lever is slid in the axial direction while gripping the handle grip, and the gear is changed and the motorcycle is shifted, thereby adjusting the speed. I do.

[Example] Hereinafter, an example of this invention will be described in detail based on the drawings.

Figures 1 to 5 show examples of this invention;
In FIG. 5, 2 is a manual operating mechanism (not shown) of an electric transmission, 4 is a handle grip, 6 is a clutch lever, and 8 is a handle bar. The operating mechanism 2 is divided into a movable part 10 and a fixed part 12,
The movable part 10 is formed by the handle grip 4, the clutch lever 6, and the first handlebar 8a, and the fixed part 12 is formed by the second handlebar 8b. That is, the handlebar 8 is divided into first and second handlebars 8a and 8b, with a square prism-shaped protrusion 14 provided at one end of the first handlebar 8a and a square prism-shaped recess 16 provided in the second handlebar 8b. and are attached so that they can slide in the axial direction.

Further, as shown in FIG. 2, a holding mechanism 18 for suppressing the sliding movement range of the movable part 10 is provided,
This holding mechanism 18 is formed by a groove 20 provided on the fixed part 12 side and a protrusion 22 provided on the movable part 10 side that slides within this groove 20. At this time, a spring mechanism 28 consisting of first and second springs 24 and 26 is disposed between the protrusion 22 and the groove 20 to maintain the neutral position C, and the sliding surface between the protrusion 22 and the groove 20 A moderation mechanism 30 consisting of a ball catch or the like is provided in the movable portion 10 to moderate the sliding movement of the movable portion 10.

Furthermore, a switch part 32 for operating an electric transmission (not shown) is provided on the sliding surface between the protrusion part 22 and the groove part 20, and this switch part 32 is installed on the upper surface of an insulator 34 buried in the groove part 20. It is formed by a side conductor 36 and a ball 38 which is a movable side conductor of the moderation mechanism 30.

Furthermore, as shown in FIG.
An operation completion confirmation mechanism 40 is provided between the movable part 10 and the operation completion confirmation mechanism 40.
, a plunger 44 , and a groove-like engagement portion 46 provided on the movable portion 10 that engages and disengages from the tip of the plunger 44 as the plunger 44 moves in the vertical direction.

Next, the effect will be explained.

While the motorcycle is running at a desired vehicle speed, when decreasing the vehicle speed, the movable part 10 is moved by the spring mechanism 2 while grasping the handle grip 4.
8 and the moderation mechanism 30, and slide inward. As a result, the protrusion 14 of the movable part 10 is slid in the insertion direction, which is the axial direction, relative to the recess 16 of the fixed part 12, and the protrusion 22 of the movable part 10 is slid within the groove 20 of the fixed part 12. , the low-speed side first conductor 36a and the ball 38, which is the movable side conductor, are brought into contact and the electric transmission (not shown) is downshifted to perform deceleration.

Further, when increasing the vehicle speed while driving, the movable part 10 is slid outward while grasping the handle grip 4. As a result, the protrusion 14 slides relative to the recess 16 in the axial escape direction, and the protrusion 2 moves inside the groove 20.
2 slides to bring the high-speed side second conductor 36b into contact with the ball 38, thereby upshifting the transmission (not shown) and accelerating. After the speed change operation is completed, the movable part 10 is slid by the spring mechanism 28 and positioned at the neutral position C by the moderation mechanism 30.

Furthermore, by providing the operation completion confirmation mechanism 40, during acceleration/deceleration operations by sliding the movable portion 10, the tip of the plunger 44 and the groove-shaped engagement portion are connected to each other as shown by the dashed line in FIG. 4
6 provides moderation to the sliding movement. When the speed change operation is finished, the solenoid 42 is energized and the plunger 44 is pulled down, as shown by the broken line in FIG.
6, the movable part 10 is further slid inward or outward, and the fixed part 1
2. This makes it possible to directly notify the operator of the end of the speed change operation, which is advantageous in practice, since the operator does not have to perform more slide movement operations than necessary.

Further, in the gear shifting operation, the gear shifting can be done without moving the fingers while grasping the handle grip, which improves safety during driving, simplifies the operation, and helps prevent erroneous operation. .

It should be noted that this invention is not limited to the above-mentioned embodiments, and can be modified in various ways.

For example, in the embodiment of this invention, a rectangular prism-shaped recess 16 and a rectangular prism-shaped protrusion 14 are formed in the fixed part 12 and the movable part 10, respectively, so that the fixed part 12 and the movable part 10 are installed so that they can be slidably moved without being rotated. However,
As shown in FIGS. 6a to 6c, the recess 16 and the protrusion 14 can be formed into a triangular prism shape, two or more cylindrical shapes, or a keyed cylindrical shape. In this way, the movable part can be slid without being rotated, and there is no problem of deterioration in operability.

[Effects of the invention] As explained in detail above, according to this invention, the movable part consisting of the handle grip and the clutch lever is attached to the fixed part consisting of the handlebar so as to be slidable in the axial direction. The movable part can be slid in the axial direction to change gears, thereby improving operability and driving safety. Furthermore, the gear shifting operation is simplified and erroneous operations can be prevented.
