Description

  The present invention relates to a steering wheel provided in a vehicle.

  A vehicle such as an automobile is provided with a steering handle for operating a tire turning angle. Patent Document 1 discloses a steering handle in which a portion (grip portion) gripped by a driver extends along the vehicle width direction.

JP 2002-209308 A

  If the maximum operating angle of the steering handle is increased, the bending angle of the wrist when the actual operating angle is increased is increased, which makes it difficult to operate the steering handle. On the other hand, if the maximum steering angle of the steering wheel is reduced, it becomes easier to operate the steering wheel, but the amount of change in the tire turning angle with respect to the steering wheel operation increases, so the operability of the vehicle is poor. turn into.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a steering wheel that can be easily operated over a wide operating angle range.

  A steering handle for solving the above-described problems is provided in the handle body in a manner capable of relatively rotating around a shaft center of the steering shaft, and a handle body having a shaft fixing portion fixed to a steering shaft of a vehicle. And a fixed gear having a column fixing portion fixed to a steering column, and a grip portion and a planetary gear which are provided in the handle body in a manner rotatable around a position different from the axis, An intermediate gear that is rotatably provided on the handle main body and meshes with the fixed gear and the planetary gear, the gear ratio of the fixed gear and the intermediate gear, and the planetary gear and the intermediate gear. The gear ratio is the same.

  In the above-described configuration, the handle main body is rotated because the fixed gear integrated with the steering column, the planetary gear integrated with the handle, and the intermediate gear meshing with the fixed gear and the planetary gear are provided. Therefore, when the grip portion of the handle portion is gripped and rotated, the handle portion rotates in a direction opposite to the rotation direction of the handle body. Moreover, since the gear ratio of the fixed gear and the intermediate gear and the gear ratio of the planetary gear and the intermediate gear are the same, the operation angle of the handle body and the rotation angle of the handle portion with respect to the handle body are the same. For this reason, when the handle body is rotated, the handle portion is rotated by the same angle as the angle of rotation of the handle body in the opposite direction.

  Therefore, according to the above configuration, the rotation angle is constant (for example, the grip portion) so that the rotation angle of the handle portion with respect to the vehicle body (steering column) does not change regardless of the rotation operation angle of the handle body. Can be held at an angle that extends in the horizontal direction. As a result, even when the actual operation angle of the steering handle is increased, the wrist bending angle hardly changes, so that the steering handle can be easily operated over a wide operating angle range.

In the steering wheel, the grip portion preferably functions as an accelerator operation member operated during vehicle acceleration.
According to the above configuration, both the operation of changing the steering angle of the vehicle and the accelerator operation can be easily performed through the operation of the grip portion while being held with one hand.

In the steering handle described above, it is preferable that the grip portion is an accelerator grip that is rotatably provided on the handle portion so that a rotation shaft extends in a vehicle width direction.
According to the above configuration, the grip portion can be realized by using the accelerator operation member having a structure that rotates the accelerator grip extending in the vehicle width direction, that is, a highly reliable structure adopted in a motorcycle or the like. .

  In the steering handle, the intermediate gear has a two-stage structure including two gears having different diameters of the pitch circle. One of the two gears meshes with the fixed gear, and the other is the planetary gear. It is preferable to mesh.

  According to the above configuration, the relationship between the number of teeth of the fixed gear and the number of teeth of the planetary gear can be determined with a high degree of freedom through the setting of the number of teeth of the two gears constituting the intermediate gear. According to the shape of each part, the size of the fixed gear and the size of the planetary gear can be determined with a high degree of freedom. As a result, the shape of each part of the steering handle can be determined with a high degree of freedom, and thus a steering handle having high design properties can be easily realized.

In the steering handle, the intermediate gear is composed of one gear, and the diameter of the pitch circle of the fixed gear and the diameter of the pitch circle of the planetary gear are the same.
According to the above configuration, the gear ratio of the fixed gear and the intermediate gear and the gear ratio of the planetary gear and the intermediate gear can be made the same.

  In the steering handle, a first reel that rotates integrally with the fixed gear, a second reel that rotates integrally with the planetary gear, a winding direction by the first reel, and a winding direction by the second reel are opposite directions. It is preferable to have an electric wire wound around the first reel and the second reel.

  According to the above configuration, when the steering handle is provided with an electric wire for connecting the steering column (fixed gear) and the handle portion, the electric wire is automatically adjusted according to the relative movement of the fixed gear and the handle portion. It can be fed out from one of the first reel and the second reel and taken up on the other. Thereby, the relative position between the portion on the steering column (fixed gear) side of the electric wire and the fixed gear and the relative position between the portion on the handle portion side and the handle portion can be hardly changed. Therefore, the electric wire can be installed between the relatively moving members (fixed gear and handle portion) while suppressing the force acting on the electric wire.

  In the steering handle, the handle body has a wheel portion that extends in an annular shape around the shaft fixing portion, and the handle portion has a shape that partially protrudes radially outward of the wheel portion. preferable.

  According to the said structure, the space which can arrange | position a handle part can be enlarged compared with the thing of the structure where a handle part is stored in the radial inside of a wheel part. Thereby, since the freedom degree of the shape setting of a grip part becomes high, it can be set as the structure which is easy to hold | grip the grip part by lengthening a grip part. In addition, since it is possible to dispose the grip portion away from the shaft fixing portion, the force point at which the force for operating the grip portion can be moved away from the axis of the steering shaft, and the steering handle can be operated. The power can be reduced.

  According to the steering wheel of the present invention, it can be easily operated over a wide operating angle range.

Hereinafter, an embodiment of the steering handle will be described.
As shown in FIG. 1, the handle main body 20 includes a shaft fixing portion 21 that is disposed at a central portion in a front view and is fixed to the steering shaft 11 of the vehicle, and a wheel portion that extends in an annular shape around the shaft fixing portion 21. 22. Further, a cover 23 is attached to the handle body 20 so as to cover the driver seat side (the front side in FIG. 1) of the shaft fixing portion 21. A gear mechanism and a reel mechanism are provided at a portion of the handle body 20 covered with the cover 23. These gear mechanism and reel mechanism will be described in detail later. Note that the steering handle of the present embodiment is for operating the turning angle of the tire of the vehicle, and more than one rotation (for example, one and a half rotations) to the left and right from the operation angle (neutral position) at which the vehicle goes straight. ) It is designed to rotate.

  The handle main body 20 is provided with a handle portion 24 so as to be rotatable around a position L2 different from the axis L1 of the steering shaft 11. The handle portion 24 includes a cylindrical rotating portion 25 and a grip portion 26 that extends in the diameter direction inside the rotating portion 25. The grip portion 26 is an accelerator grip that is formed in a shape that can be gripped by the driver, and that is rotatably provided on the handle portion 24 in a manner in which the rotation shaft extends in the vehicle width direction. In the present embodiment, the grip portion 26 functions as an accelerator operation member that is operated during vehicle acceleration. A part of the handle portion 24 protrudes to the outside in the radial direction of the wheel portion 22.

  As shown in FIG. 2, a plate 27 is fixed to a portion of the handle body 20 covered with a cover 23 (see FIG. 1). The plate 27 extends in a direction intersecting the axis L1 of the steering shaft 11. The plate 27 is provided with a gear mechanism 30 including a fixed gear 31, a planetary gear 32, and an intermediate gear 33.

  The fixed gear 31 is rotatably attached to the plate 27. The fixed gear 31 is disposed at a position where the center of the pitch circle of the fixed gear 31 and the axis L1 of the steering shaft 11 coincide with the steering handle attached to the vehicle.

  The planetary gear 32 is provided on the outer surface of the rotating portion 25 (see FIG. 1) of the handle portion 24 so as to be integrally rotatable. The center of the pitch circle of the planetary gear 32 and the axis L2 of the rotation center of the rotating unit 25 are the same. In the steering handle of this embodiment, the driver's seat side (the front side in FIG. 2) of the planetary gear 32 is covered with the cover 23 (see FIG. 1), so that the planetary gear 32 cannot be seen from the driver's seat side. It has become.

  The intermediate gear 33 is rotatably attached to the plate 27. The rotation center axis L3 of the intermediate gear 33 is different from the rotation center axis L1 of the fixed gear 31 (the axis of the steering shaft 11) and the rotation center axis L2 of the planetary gear 32. In the present embodiment, the rotation center axis L1 of the fixed gear 31, the rotation center axis L2 of the planetary gear 32, and the rotation center axis L3 of the intermediate gear 33 are parallel to each other. The intermediate gear 33 is operated in the same manner as the first gear 34 having a small diameter disposed on the side farther from the driver's seat (the back side of the drawing in FIG. 2), which is composed of two gears having different pitch circle diameters. It has a two-stage structure including a large-diameter second gear 35 arranged on the seat side (the front side in FIG. 2). The intermediate gear 33 is arranged in such a manner that the first gear 34 meshes with the fixed gear 31 and the second gear 35 meshes with the planetary gear 32. In the present embodiment, the second gear 35 is not meshed with the fixed gear 31, and the first gear 34 is not meshed with the planetary gear 32.

  The shapes of the fixed gear 31, the planetary gear 32 and the intermediate gear 33 are the ratio of the number of teeth Z1 of the fixed gear 31 and the number of teeth Z2 of the first gear 34 (gear ratio Rs = Z1 / Z2) to the planetary gear 32. The ratio of the number of teeth Z3 and the number of teeth Z4 of the second gear 35 (gear ratio Rp = Z3 / Z4) is determined to be the same (Rs = Rp).

  As shown in FIG. 3, on the side of the handle body 20 that is farther from the driver's seat than the plate 27 (see FIG. 2) (the back side of the page in FIG. 3), the electric wire 41 does not loosen as the steering handle rotates. A reel mechanism 40 for winding is provided. The reel mechanism 40 includes a first reel 43 fixed to the fixed gear 31 and a second reel 44 fixed to the planetary gear 32.

  The first reel 43 has a cylindrical shape centered on the center L1 of the pitch circle of the fixed gear 31 (see FIG. 2), and rotates integrally with the fixed gear 31. Further, an end portion of the first reel 43 far from the driver's seat is a column fixing portion 45. When the steering handle is attached to the vehicle, the column fixing portion 45 is fixed to the steering column 12 (see FIG. 1). As a result, the first reel 43 and the fixed gear 31 are fixed to the steering column 12 and can be rotated relative to the steering shaft 11 about the axis L1 of the steering shaft 11. The second reel 44 has a cylindrical shape centered on the axis L2 of the rotation center of the planetary gear 32 (see FIG. 2), and rotates integrally with the planetary gear 32. The outer diameter of the first reel 43 and the outer diameter of the second reel 44 are the same.

  An electric wire 41 for connecting an accelerator sensor (not shown) provided on the grip portion 26 and an electronic control device (not shown) provided on the vehicle body is attached to the steering handle of the present embodiment. One end of the electric wire 41 is connected to the accelerator sensor, and the other end is connected to a connector for connection and is exposed from the shaft fixing portion 21 to the outside of the steering handle. The electric wire 41 is wound around the first reel 43 and the second reel 44. In the present embodiment, the winding direction of the electric wire 41 by the first reel 43 (counterclockwise direction in FIG. 3) and the winding direction of the electric wire 41 by the second reel 44 (clockwise direction in FIG. 3) are opposite to each other. It has become.

Hereinafter, functions and effects obtained by employing the steering wheel described above will be described.
The steering handle has a gear mechanism 30 including a fixed gear 31 integrated with the steering column 12, a planetary gear 32 integrated with the handle portion 24, and an intermediate gear 33 meshing with the fixed gear 31 and the planetary gear 32. Yes. Therefore, when the rotation is performed with the grip portion 26 of the handle portion 24 held to rotate the handle body 20, the handle portion 24 is opposite to the rotation direction of the handle body 20 through the operation of the gear mechanism 30. Rotate in the direction.

  In the steering handle, the gear ratio Rs of the fixed gear 31 and the intermediate gear 33 and the gear ratio Rp of the planetary gear 32 and the intermediate gear 33 are the same. Therefore, if the state in which the steering handle is in the neutral position (the state shown in FIG. 2) is the reference angle (0 degree), the operation angle of the handle body 20 and the rotation angle of the handle portion 24 with respect to the handle body 20 are the same. become. Therefore, in the steering handle, when the handle body 20 is rotated, the handle portion 24 is rotated by the same angle as the angle of rotation of the handle body 20 in the direction opposite to the rotation direction.

  Specifically, in the example shown in FIG. 2, the operation angle of the handle body 20 is the reference angle (0 degree), and the rotation angle of the handle portion 24 is also the reference angle (0 degree). At this time, the grip 26 extends in the vehicle width direction (horizontal direction).

  Further, in the example shown in FIG. 4A, since the operation angle of the handle body 20 is an angle rotated “90 degrees” in the clockwise direction, the rotation angle of the handle portion 24 is “90” in the counterclockwise direction. The angle will be the "degree" rotated. Therefore, the grip part 26 is held in a state extending in the horizontal direction.

  Further, in the example shown in FIG. 4B, since the operation angle of the handle body 20 is an angle rotated by “180 degrees” in the clockwise direction, the rotation angle of the handle portion 24 is “180 degrees in the counterclockwise direction. “It becomes a rotated angle. Therefore, at this time, the grip portion 26 is held in a state of extending in the horizontal direction.

  In the example shown in FIG. 4C, since the operating angle of the handle body 20 is an angle rotated “270 degrees” in the clockwise direction, the rotating angle of the handle portion 24 is “270 degrees” in the counterclockwise direction. It becomes a rotated angle. Thereby, the grip part 26 comes to be hold | maintained with the state extended in a horizontal direction.

  As described above, according to the present embodiment, the rotation angle of the handle portion 24 with respect to the vehicle body (the steering column 12 [FIG. 1]) does not change regardless of the operating angle of the handle body 20. The rotation angle can be kept constant (specifically, the angle at which the grip portion 26 extends in the horizontal direction). Thereby, even when the actual operation angle of the steering handle (specifically, the handle body 20) is increased, the bending angle of the hand (wrist) holding the grip portion 26 hardly changes. The steering handle can be easily operated over a wide operation range.

  In particular, the steering handle of the present embodiment is configured to rotate one or more times to the left and right (for example, from the neutral position to the locked position rotated by one and a half rotations). Therefore, if the rotation angle of the grip portion with respect to the handle body does not change, the handle portion cannot be operated unless the grip portion is changed when the operation angle of the handle body increases. Therefore, in this case, the steering handle cannot be operated with the grip portion held with one hand in the entire operation range. According to the present embodiment, although the steering handle rotates one or more times to the left and right, the rotation angle of the grip portion 26 with respect to the steering column 12 can be kept constant, so the grip portion 26 can be held with one hand. Operation in the entire operation range of the steering wheel while being held can be realized.

  A part of the handle portion 24 protrudes outward in the radial direction of the wheel portion 22. As a result, the space in which the handle portion 24 can be disposed is larger than that of a structure in which the handle portion is accommodated in the radially inward direction of the wheel portion, so that the degree of freedom in setting the shape of the grip portion 26 is increased. . Therefore, the dimension of the grip part 26 in the horizontal direction can be lengthened so that the grip part 26 can be easily gripped. Moreover, since the grip portion 26 can be disposed far from the axis L1 of the steering shaft 11, the force point at which the force for operating the grip portion 26 can be moved away from the coaxial center L1, and the steering handle The operation force can be reduced.

  The grip portion 26 of the steering handle is an accelerator grip that is rotatably provided on the handle portion 24 in such a manner that the rotation shaft extends in the vehicle width direction (horizontal direction). And according to this embodiment, since this grip part 26 is hold | maintained in the state extended in a horizontal direction, operation (specifically, axial center L1 of the steering shaft 11) of the grip part 26 in the state hold | gripped with one hand. Both the steering angle change operation and the accelerator operation of the vehicle can be easily performed through the operation of rotating the handle body 20 about the rotation axis and the operation of rotating the grip portion 26 about the rotation axis of the grip portion 26). it can. Further, the grip portion 26 having such a structure can be realized by using a structure for rotating an accelerator grip extending in the vehicle width direction, that is, using an accelerator operation member having a highly reliable structure employed in a motorcycle or the like. .

  Here, in the present embodiment, the fixed gear 31 and the planetary gear 32 are covered with the cover 23 so as not to be seen from the driver's seat side in order to impart high designability to the steering handle. For this reason, if the fixed gear 31 is enlarged, the cover 23 covering the fixed gear 31 must be enlarged accordingly, and the design constraints on the steering wheel are increased. From this, it can be said that the fixed gear 31 is preferably small. On the other hand, when the planetary gear 32 is made smaller, the handle portion 24 with which the planetary gear 32 is integrally provided also becomes smaller, and the grip portion 26 in the handle portion 24 becomes shorter, making it difficult to grip the grip portion 26. Therefore, it can be said that the planetary gear 32 is preferably large.

  In view of this situation, in the present embodiment, the intermediate gear 33 having a two-stage structure including the first gear 34 and the second gear 35 having different diameters of the pitch circle is employed, and the first gear 34 is used as the fixed gear 31. The second gear 35 meshes with the planetary gear 32 while meshing.

  Thus, as described above, the gear ratio Rs of the fixed gear 31 and the intermediate gear 33 and the gear ratio Rp of the planetary gear 32 and the intermediate gear 33 are set to be the same, but the number of teeth of the first gear 34 is By setting the relationship with the number of teeth of the second gear 35, the relationship between the number of teeth of the fixed gear 31 and the number of teeth of the planetary gear 32 can be determined with a high degree of freedom. Therefore, the size of the fixed gear 31 and the size of the planetary gear 32 can be determined with a high degree of freedom in accordance with the shape of each part of the steering handle. Thereby, since it becomes possible to determine the shape of each part (the cover 23 and the handle | steering-wheel part 24) of a steering handle with a high freedom degree, the steering handle which has high designability is easily realizable. In the present embodiment, the fixed gear 31 is smaller than the planetary gear 32.

  The steering handle is provided with an electric wire 41 for connecting the electronic control device of the vehicle body and the accelerator sensor of the handle portion 24. The electric wire 41 is wound around a first reel 43 integral with the fixed gear 31 and a second reel 44 integral with the planetary gear 32 such that the winding direction is opposite. As a result, as shown in FIGS. 5A to 5D, the electric wire 41 is automatically moved in accordance with the relative movement between the steering column 12 (fixed gear 31) and the handle portion 24. It is fed from one of the second reels 44 and taken up by the other. In addition, since the outer diameter of the first reel 43 and the outer diameter of the second reel 44 are the same, the feed amount of the electric wire 41 from one of the first reel 43 and the second reel 44 and the electric wire to the other The amount of winding 41 is substantially the same.

  Hereinafter, the operation of the reel mechanism 40 when the handle body 20 is rotated by 90 degrees counterclockwise will be specifically described. The case where the handle body 20 is rotated counterclockwise by 90 degrees includes, for example, the case where the handle body 20 is operated from the state shown in FIG. 5D to the state shown in FIG. 5C, or the state shown in FIG. 5B, the state of FIG. 5B is changed to the state of FIG. 5A, the state of FIG. 5A is changed to the state of FIG. 5D. The case where it is operated to. In this case, while the first reel 43 is fixed to the steering column 12, the handle body 20 rotates by 90 degrees counterclockwise with respect to the steering column 12. Therefore, the electric wire 41 having a length of about ¼ of the outer circumference of the first reel 43 is sent out from the first reel 43. At this time, the second reel 44 integrated with the handle portion 24 is rotated 90 degrees clockwise with respect to the handle body 20. Therefore, the electric wire 41 having a length of about ¼ of the outer circumference of the second reel 44 is wound around the second reel 44.

  Next, the operation of the reel mechanism 40 when the handle body 20 is rotated 90 degrees clockwise will be specifically described. Note that the case where the handle body 20 is rotated 90 degrees clockwise is the case where the handle body 20 is operated from the state of FIG. 5D to the state of FIG. 5A, or the state of FIG. When operated to the state of (b), when operated from the state of FIG. 5 (b) to the state of FIG. 5 (c), it is operated from the state of FIG. 5 (c) to the state of FIG. 5 (d). And so on. In this case, while the first reel 43 is fixed to the steering column 12, the handle body 20 rotates 90 degrees clockwise with respect to the steering column 12. Therefore, the electric wire 41 having a length that is approximately ¼ of the outer circumference of the first reel 43 is wound around the first reel 43. At this time, the second reel 44 integrated with the handle portion 24 is rotated by 90 degrees counterclockwise with respect to the handle body 20. Therefore, the electric wire 41 having a length of about ¼ of the outer circumference of the second reel 44 is sent out from the second reel 44.

  In this way, the reel mechanism 40 feeds and winds the electric wire 41, the relative position between the end of the electric wire 41 on the steering column 12 (fixed gear 31 integrated with the first reel 43) side and the fixed gear 31, This can be performed in a state in which the relative position between the end portion on the handle portion 24 side integrated with the second reel 44 of the electric wire 41 and the handle portion 24 hardly changes. Therefore, the electric wire 41 can be installed between the relatively moving members (the fixed gear 31 and the handle portion 24) while the force acting on the electric wire 41 is kept small.

As described above, according to the present embodiment, the following effects can be obtained.
(1) A gear mechanism 30 including a fixed gear 31 integral with the steering column 12, a planetary gear 32 integral with the handle portion 24, and an intermediate gear 33 meshing with the fixed gear 31 and the planetary gear 32 is provided on the steering handle. It was. The gear ratio Rs of the fixed gear 31 and the intermediate gear 33 (first gear 34) and the gear ratio Rp of the planetary gear 32 and the intermediate gear 33 (second gear 35) are made the same. Therefore, the steering handle can be easily operated over a wide operation range.

  (2) The grip portion 26 of the steering handle is made to function as an accelerator operation member operated during vehicle acceleration. Therefore, both the operation of changing the steering angle of the vehicle and the accelerator operation can be easily performed through the operation of the grip portion 26 in a state of being held with one hand.

It meshes with the planetary gear 32. As a result, the shape of each part of the steering handle can be determined with a high degree of freedom, and thus a steering handle having high design properties can be easily realized.

  (5) The first reel 43 integrated with the fixed gear 31, the second reel 44 integrated with the planetary gear 32, and the winding directions of the first reel 43 and the second reel 44 are opposite to each other. A reel mechanism 40 including a wire 41 wound around is provided. Therefore, the electric wire 41 can be installed between the stationary gear 31 and the handle portion 24 that move relative to each other while the force acting on the electric wire 41 is kept small.
