2. Description of the Related Art Conventionally, for example, in straddle-type vehicles for competitions, a system (clutchless shift system) has been adopted that detects a shift operation by a driver and changes the gear position without engaging or disconnecting a clutch. A straddle-type vehicle that employs such a system detects shift operations (upshifts, downshifts, etc.) by the driver, and also requires clutch engagement/disengagement operations based on the detected shift operation information. The structure is such that the gear position can be changed without any trouble.

Here, the shift operation by the driver is detected by a shift operation detection device connected to the shift pedal. It is desired that the shift operation detection device accurately detect the shift operation without impairing the shift operability by the driver.

On the other hand, there is a shift rod whose one end is connected to the shift pedal, an elastic member that applies a biasing force to the shift rod (rod body), and a linear movement in the longitudinal direction corresponding to the shift operation on the shift rod (rod body). A shift operation detection device has been proposed that includes a detection unit that detects the shift operation (see, for example, Patent Document 1).

Further, the biasing member 140 is arranged on a second rotation axis R2 such that when the lever member 120 rotates, the center line C of the biasing member 140 maintains a state substantially parallel to the tangential direction in the rotational movement direction. The configuration is such that the inclination of the center line C viewed from the direction is continuously changed according to the rotational movement (see FIGS. 5A, 5B, and 5D). The biasing member 140 is arranged so that when the lever member 120 rotates, the center line C of the biasing member 140 is centered when viewed from the second rotation axis R2 direction so that the angle between the center line C of the biasing member 140 and the tangential direction in the rotational movement direction becomes small. The inclination of the line C is configured to be continuously changed according to the rotational movement (see FIGS. 5A, 5B, and 5D).

It can be suppressed.

The detection unit 180 is configured to detect rotational movement of the lever member 120 in response to a shift operation, and to output the detection result as shift operation information. The detection unit 180 includes a magnet 181 and a sensor module 184. The detection unit 180 is configured to detect rotational movement of the lever member 120 in response to a shift operation, and to output the detection result as shift operation information.

The sensor module 184 (Hall IC 184a) is configured to be able to detect changes in magnetic flux density that occur in response to movement of the magnet 181 accommodated in the magnet accommodating portion 136 of the lever member 120. In this embodiment, the sensor module 184 (Hall IC 184a) outputs the detection result as an analog voltage (shift operation information).

Next, the operation of the shift operation detection device 101 in the embodiment will be described with reference to FIGS. 5A to 7C.
First, as shown in FIGS. 5A, 6A, and 7A, the shift operation detection device 101 detects that the lever member 120 is at the reference position when the shift pedal 20 (see FIG. 1) is not receiving a shift operation (reference state). will be placed in

In this embodiment, the distance between the first contact portion 132 and the second contact portion 134 of the lever member 120 is the same distance as the distance between the first restriction portion 117 and the second restriction portion 118 of the cover portion 110. It has become. As a result, the biasing member 140 uses the biasing force of the biasing member 140 to cause the first restricting portion 117 and the second restricting portion 118 of the cover portion 110 to move in the reference state in which no shift operation is applied to the lever member 120. The lever member 120 is positioned by the first abutting portion 132 and the second abutting portion 134 of the lever member 120.
In the standard state, the first engaging portion 142 abuts the first abutting portion 132 and the second restricting portion 118, and the second engaging portion 144 abuts the second abutting portion 134 and the first restricting portion 117. are in contact with each other.

Continuously, as shown in FIGS. 5B, 6B, and 7B, when the shift operation detection device 101 receives a shift operation (for example, downshift) from the shift pedal 20 (see FIG. 1), the lever member 120 moves to the second position. It is rotated once in the rotation direction A1. In this state, the lever member 120 is urged by the elastic member 145 in a direction opposite to the rotation direction A1 (direction of returning to the reference position).

Here, when the lever member 120 rotates around the second rotation axis R2, the first contact portion 132 contacts the first engagement portion 142 of the biasing member 140 and the first engagement portion 142 (one end of the biasing member 140) is moved in the first rotation direction A1.
On the other hand, in the first regulating part 117, the first abutting part 132 of the lever member 120 abuts the first engaging part 142 of the urging member 140, and the first restricting part 117 When the one end) is moved in the first rotation direction A1, it comes into contact with the second engaging part 144 of the biasing member 140 and the second engaging part 144 (the other end of the biasing member 140) is moved in the first rotation direction A1. Movement in direction A1 is restricted.

Specifically, when the lever member 120 rotates in the first rotation direction A1, the first abutting portion 132 abuts the first engaging portion 142 of the biasing member 140, and the second abutting portion 134 is separated from the second engaging portion 144 of the biasing member 140.
Further, when the lever member 120 rotates in the first rotation direction A1, the first restriction part 117 comes into contact with the second engaging part 144 of the biasing member 140, and the second restriction part 118 contacts the second engagement part 144 of the biasing member 140. 140 and is separated from the first engaging portion 142 of the first engaging portion 140 .

Further, when the lever member 120 rotates in the first rotation direction A1, the first engagement portion 142 and the first contact portion 132 engage with each other in a rotationally slidable manner, and the second engagement portion The portion 144 and the first restricting portion 117 are rotatably and slidably engaged with each other. Thereby, the biasing member 140 is compressed while maintaining a state in which the center line C is parallel to the tangential direction of the rotation direction. In other words, the force applied from the first contact portion 132 to the biasing member 140 is a force in a direction parallel to the center line C. As a result, it is possible to suppress the force applied to the biasing member 140 from being applied in a direction (oblique direction) intersecting the center line C, thereby preventing problems such as damage to the biasing member 140 (elastic member 145). can be suppressed

The shift operation detection device 101 (sensor module 184) detects a change in magnetic flux density caused by the movement of the magnet 181 housed and fixed in the magnet accommodating portion 136 of the lever member 120, and converts the detected shift operation information into an analog voltage. Output. The engine control unit 213 (see FIG. 2) controls the output of the engine unit 12 (for example, performs blipping control) based on the shift operation information output from the shift operation detection device 101 (sensor module 184).

Subsequently, as shown in FIG. 5C, when a shift operation (for example, downshift) is further received from the shift pedal 20 (see FIG. 1), the shift operation detection device 101 rotates around the first rotation axis R1. It is rotated in the moving direction B1. As a result, the shift shaft 21 is rotated, and a shift operation is transmitted to the transmission 18.

When the transmission 18 receives a shift operation (depression operation by the driver) via the shift lever device 100, the gear position is changed (downshifted). Here, since the output of the engine unit 12 is controlled, the transmission 18 changes the gear position while suppressing the load between the gears even if the clutch is not engaged or disconnected. In other words, a non-clutch shift is executed.

When the shift operation on the shift pedal 20 (see FIG. 1) is released, the shift operation detection device 101 returns to the reference state by rotating around the first rotation axis R1, and the lever member 120 is biased. Due to the biasing force from the member 140, it returns to the standard state by rotationally moving about the second rotation axis R2 (see FIG. 5A).

Continuously, as shown in FIGS. 5D, 6C, and 7C, when the shift operation detection device 101 receives a shift operation (for example, upshift) from the shift pedal 20 (see FIG. 1), the lever member 120 moves to the second position. It is rotated twice in the rotation direction A2. In this state, the lever member 120 is urged by the elastic member 130 in a direction opposite to the rotation direction A2 (direction of returning to the reference position).

Here, when the lever member 120 rotates about the second rotation axis R2, the second contact portion 134 contacts the second engagement portion 144 of the biasing member 140 and the second engagement portion 144 (the other end of the biasing member 140) is moved in the second rotation direction A2.
On the other hand, in the second regulating part 118, the second abutting part 134 of the lever member 120 abuts the second engaging part 144 of the urging member 140, and the second restricting part 118 When the other end) is moved in the second rotation direction A2, it comes into contact with the first engaging part 142 of the biasing member 140 and the second rotation of the first engaging part 142 (one end of the biasing member 140) Movement in direction A2 is restricted.

Specifically, when the lever member 120 rotates in the second rotation direction A2, the second contact portion 134 contacts the second engagement portion 144 of the biasing member 140, and the first contact portion 132 is separated from the first engaging portion 142 of the biasing member 140.
Further, when the lever member 120 rotates in the second rotation direction A2, the second restriction part 118 comes into contact with the first engaging part 142 of the biasing member 140, and the first restriction part 117 140 and is separated from the second engaging portion 144 of the second engaging portion 144 .

Further, when the lever member 120 rotates in the second rotation direction A2, the second engagement portion 144 and the second contact portion 134 engage with each other in a rotationally slidable manner, and The portion 142 and the second restriction portion 118 are rotatably and slidably engaged with each other. As a result, the biasing member 140 is compressed so that the center line C remains parallel to the tangential direction of the rotation direction. In other words, the force applied from the second contact portion 134 to the biasing member 140 is a force in a direction parallel to the center line C. As a result, it is possible to suppress the force applied to the biasing member 140 from being applied in a direction (oblique direction) intersecting the center line C, thereby preventing problems such as damage to the biasing member 140 (elastic member 145). can be suppressed

The shift operation detection device 101 (sensor module 184) detects a change in magnetic flux density caused by the movement of the magnet 181 housed and fixed in the magnet accommodating portion 136 of the lever member 120, and converts the detected shift operation information into an analog voltage. Output. Then, the engine control unit 213 (see FIG. 2) controls the output of the engine unit 12 (for example, ignition cut and fuel cut) based on the shift operation information output from the shift operation detection device 101 (sensor module 184). do.

Subsequently, as shown in FIG. 5E, when a shift operation (for example, upshift) is further received from the shift pedal 20 (see FIG. 1), the shift operation detection device 101 rotates around the first rotation axis R1. It is rotated in the moving direction B2. As a result, the shift shaft 21 is rotated, and a shift operation is transmitted to the transmission 18.

When the transmission 18 receives a shift operation (a kick-up operation by the driver) via the shift lever device 100, the gear position is changed (upshifted). Here, since the output of the engine unit 12 is controlled, the transmission 18 changes the gear position while suppressing the load between the gears even if the clutch is not engaged or disconnected. In other words, a non-clutch shift is executed.

When the shift operation on the shift pedal 20 (see FIG. 1) is released, the shift operation detection device 101 returns to the reference state by rotating around the first rotation axis R1, and the lever member 120 is biased. Due to the biasing force from the member 140, it returns to the standard state by rotationally moving about the second rotation axis R2 (see FIG. 5A).

As described above, when the lever member 120 rotates, the biasing member 140 rotates for a second time so that the center line C of the biasing member 140 remains substantially parallel to the tangential direction in the rotational movement direction. The inclination of the center line C viewed from the direction of the axis R2 is continuously changed according to the rotational movement (see FIGS. 5A, 5B, and 5D). As a result, it is possible to suppress the force applied to the biasing member 140 from being applied in a direction (oblique direction) intersecting the center line C, thereby preventing problems such as damage to the biasing member 140 (elastic member 145). It can be suppressed.

According to the shift operation detection device 101 of this embodiment, the following effects are achieved.
According to the present embodiment, it is possible to provide a shift operation detection device that can be used even when the distance from the shift pedal to the shift shaft is short. According to this embodiment, since the shift operation detection device is rotatably attached to the shift shaft, the shift operation detection device can function as a shift lever device. Thereby, the shift operation detection device can be implemented even in a straddle-type vehicle in which the distance from the shift pedal to the shift shaft is short.
Further, according to the present embodiment, it is possible to provide a shift lever device and a straddle-type vehicle including the shift operation detection device.

Further, the shift operation detection device is directly or indirectly connected to the shift rod, and can convert linear movement of the shift rod into rotational movement. Further, the shift operation detection device can detect a shift operation by detecting rotational movement of the lever member, and can output the detection result as shift operation information.

Further, the shift operation detection device includes a biasing member arranged to be compressed in response to rotational movement of the lever member. Thereby, the shift operation detection device can apply an appropriate load to the shift pedal during a shift operation.

Further, the biasing member 140 is arranged on a second rotation axis R2 such that when the lever member 120 rotates, the center line C of the biasing member 140 maintains a state substantially parallel to the tangential direction in the rotational movement direction.
