  Hereinafter, an embodiment of an accelerator operating device according to the present invention will be specifically described with reference to the accompanying drawings.

  As shown in FIGS. 1 to 4, the accelerator operating device 10 according to the present embodiment includes a handle grip 100 and a handle grip that are rotatably supported by the handle bar 70 by inserting a straight cylindrical handle bar 70. An accelerator member (second member) 11 composed of a grip body 72 and a yoke holder 14 attached from the end so as to cover a part of 100, and a fixing member (first member) for rotatably fixing the accelerator member 11 Member) 13 and a torsion spring 34 (first urging member) that urges the rotating accelerator member 11 in a direction to return it to its initial position (position when the accelerator operation is not performed). The The fixing member 13 includes a sensor 50 that detects the rotational position of the yoke holder 14, a friction member 16 that contacts the yoke holder 14, and a compression (coil) spring (second attachment) that biases the friction member 16 toward the yoke holder 14. Force member) 36, support member 12 for fixing and supporting compression spring 36 and torsion spring 34, part of handle grip 100, yoke holder 14, sensor 50, friction member 16, compression spring 36, torsion spring 34 and support member 12 includes an upper housing 200 and a lower housing 202.

  FIG. 3 shows a right handlebar 70 used for steering a motorcycle, for example, and shows a cross-sectional view of the accelerator operating device 10. A one-dot chain line A in FIG. 3 indicates a center line of the handle bar 70 and the handle grip 100. The arrow LH in the alternate long and short dash line A indicates the proximal end side in the axial direction of the handlebar 70 (inward in the vehicle width direction, leftward), and the arrow RH indicates the distal end side in the axial direction of the handlebar 70 (outer in the vehicle width direction (Right). Predetermined members (the yoke holder 14, the torsion spring 34, the handle grip 100, etc.) of the accelerator operating device 10 are appropriately inserted into the handle bar 70 and attached to the vehicle. The upper housing 200 and the lower housing 202 are combined from above and below the handle bar 70 while housing the sensor 50, the yoke holder 14, and the like. In this way, the accelerator operating device 10 is assembled to the handle bar 70.

  Next, each member constituting the accelerator operation device 10 will be described in detail. The handle grip 100 is made of a hard synthetic resin such as polyacetal and has a substantially cylindrical shape. A grip body 72 made of a synthetic rubber material is integrally mounted on the outer periphery of the handle grip 100. When performing the accelerator operation, the user (driver) grasps the grip body 72 and rotates the handle grip 100 with respect to the support member 12 (that is, the fixed member 13). An arc-shaped engaging protrusion 102 protruding in the axial direction is formed at an end portion of a handle grip 100 on the yoke holder 14 side, which will be described later. The engagement protrusion 102 engages with an engagement groove 142 of the yoke holder 14 described later.

  The yoke holder 14 is formed in a substantially short cylindrical shape having a flange 141 on one end face, and is a circle that engages with the engagement protrusion 102 of the handle grip 100 on the opposite surface to the surface on which the flange 141 is formed. It has an arcuate engagement groove 142 (see FIG. 1). The yoke holder 14 rotates with the rotation of the handle grip 100 when the engaging protrusion 102 and the engaging groove 142 engage with each other. Thereby, the accelerator member 11 is rotated by the accelerator operation. Further, as shown in FIG. 4, the yoke holder 14 is on the opposite side of the side where the arc-shaped engagement groove 142 is formed, and has two arcs at a position overlapping in the direction of the central axis. A dove plate-shaped yoke 144 is provided. The yoke 144 is made of a magnetic material, and two permanent magnets (not shown) are provided between both end portions of the two yokes 144. That is, a closed magnetic circuit is formed by the two yokes 144 and the permanent magnet. In addition, two projecting portions 148 (see FIG. 4) projecting in a substantially trapezoidal shape are formed on the end surface on the side where the flange 141 is formed. The yoke holder 14 is restricted from rotating (that is, the angle at which the accelerator member 11 rotates) by engaging each protrusion 148 with a rotation stopper 128 of the support member 12 (described later). Is limited). Further, a rod-shaped locking pin (second mounting portion) 140 is formed between the two projecting portions 148 so as to project from the end surface of the yoke holder 14. A free end (other end) 342 of a torsion spring 34 to be described later is attached to the locking pin 140.

  The sensor 50 is fixed to the inner surface of the lower housing 202 described later, and is disposed between the two yokes 144 of the yoke holder 14. The sensor 50 detects the leakage magnetic field generated between the two yokes 144 to detect the rotational position of the yoke holder 14.

  The friction member 16 is formed in a substantially short cylindrical shape having a flange 161 on one end face, and has four guide protrusions 164 that protrude from the inner peripheral surface of the short cylinder and are arranged every 90 degrees. The guide protrusion 164 is guided in a guide groove 124 provided in the support member 12 described later. The flange 161 of the friction member 16 (the end surface of the friction member 16) is in surface contact with the flange 141 of the yoke holder 14 (the end surface of the yoke holder 14). Further, the friction member 16 is applied with a vertical load (a load in the rotational axis direction of the accelerator member 11) in a state in which the flange 161 is in contact with the flange 141 while being urged by a compression spring 36, which will be described later. A predetermined frictional force is added to the movement. In this manner, the compression spring 36 biases the friction member 16 to press the friction member 16 against the yoke holder 14 and generates a resistance force when the accelerator member 11 rotates. This resistance force gives the driver who performs the accelerator operation a feeling of operating the accelerator. In addition, the inner surface of the friction member 16 is formed to have a size such that a protruding portion 148 of the yoke holder 14 and a rotation stopper 128 of the support member 12 described later can be inserted.

  The support member 12 has a function of fixing and supporting a compression spring 36 and a torsion spring 34 described later. The support member 12 is formed in a substantially short cylindrical shape having a flange 121 on one end face. The support member 12 is formed with a fixed claw 120 protruding from the peripheral surface of the flange 121 and a notch 122 cut out. The fixing member 120 and the notch 122 engage with recesses and projections that are appropriately formed at positions on the inner surface of the upper housing 200 and the lower housing 202, respectively. It is fixed to the housing 202. The support member 12 has four guide grooves 124 arranged every 90 degrees on the outer peripheral surface of the short cylinder. By engaging the guide groove 124 with the guide protrusion 164, the friction member 16 and the support member 12 are combined so that the center axis of the friction member 16 and the center axis of the support member 12 are coaxial. Further, this engagement prevents the friction member 16 from rotating about the central axis.

  Further, a step is formed on the inner peripheral portion of the support member 12. Five fixing holes (first mounting portions) 126 (126a to 126e) arranged at predetermined intervals on concentric circles around the rotation axis of the accelerator member 11 on the surface of the step facing the yoke holder 14 Have The fixing hole 126 is for fixing a fixing end (one end) 340 of a torsion spring 34 described later. The torsion spring 34 is accommodated in a stepped portion (a space in the step) while being fixed to the fixing hole 126.

  In addition, an arcuate rotation stopper 128 protruding from the end surface 127 is formed on the end surface 127 opposite to the flange 121 in the short cylindrical portion of the support member 12. The rotation stopper 128 limits the rotation of the yoke holder 14 by the side surface of the rotation stopper 128 coming into contact with the protruding portion 148 of the yoke holder 14.

  The compression spring 36 has a predetermined spring diameter, and is sandwiched between the flange 161 of the friction member 16 and the flange 121 of the support member 12. The compression spring 36 biases the friction member 16 with a predetermined biasing force corresponding to the number of turns and the spring diameter.

  The torsion spring 34 has a function of returning the accelerator member 11 from the rotated state to the initial state (the state where the accelerator operation is not performed), and the fixed end 340 that protrudes outward in the same direction as the central axis of the winding. And a free end 342 formed in a U-shape so as to be folded outwardly of the winding. In a state where the torsion spring 34 is attached to the support member 12, the fixed end 340 is fitted into any one of the plurality of fixed holes 126 of the support member 12, and the free end 342 is the end surface 127 of the support member 12. Located above. Further, in a state where the yoke holder 14 is attached, the free end 342 is locked to the locking pin 140 of the yoke holder 14, and when the yoke holder 14 is rotated, the yoke holder 14 is biased with a biasing force proportional to the amount of rotation.

  The upper housing 200 and the lower housing 202 are fixed to each other with screws in a state where the end of the handle grip 100, the yoke holder 14, the friction member 16, the support member 12, the compression spring 36, the torsion spring 34, and the sensor 50 are assembled. And store them. In addition, the upper housing 200 and the lower housing 202 support the handle grip 100 and the yoke holder 14 so as to be rotatable and fix the support member 12 in a state in which the above components are housed. In this state, the compression spring 36 is in a compressed state, and the friction member 16 applies a load to the yoke holder 14. In this state, the torsion spring 34 biases the handle grip 100 in a direction to return the handle grip 100 from the turning state to the initial state.

  Next, the function of the accelerator operating device 10 having the above configuration will be described. The resistance force in the accelerator operation of the accelerator operating device 10 is formed by the friction force generated between the friction member 16 and the yoke holder 14 and the elastic force in the winding direction of the torsion spring 34. The friction force is such that when the support member 12, the yoke holder 14, the friction member 16, the compression spring 36 and the torsion spring 34 are accommodated in the upper housing 200 and the lower housing 202, the compression spring 36 rotates the friction member 16 together with the handle grip 100. It is generated by urging to the moving yoke holder 14 side. Further, the elastic force (biasing force) of the torsion spring 34 changes according to the position at which the end of the torsion spring 34 is fixed to the support member 12 and the yoke holder 14. The resistance force of the accelerator operation can be adjusted by adjusting the fixed position of the torsion spring 34. The elastic force of the torsion spring is also related to the force (return force) for returning the accelerator member 11 to the initial state when the accelerator operation is released.

  As described above, since there are a plurality of fixing holes 126, the elastic force of the torsion spring 34 can be adjusted depending on which fixing hole 126 the fixing end 340 of the torsion spring 34 is fixed to. Here, a method for adjusting the elastic force of the torsion spring 34 will be described.

  When the resistance force of the accelerator operation of the accelerator operating device 10 is minimized, the fixed end 340 of the torsion spring 34 is fixed to the fixing hole 126a and the free end 342 is fixed to the locking pin 140 as shown in FIG. . In this way, in the state where the handle grip 100 is in the initial position, the displacement in the winding direction of the torsion spring 34 due to the engagement between the free end 342 of the torsion spring 34 and the engagement pin 140 is minimized. That is, by minimizing the displacement of the torsion spring 34, the resistance force of the accelerator operation and the return force when the accelerator operation is released can be minimized.

  On the other hand, when the resistance force of the accelerator operation is maximized, the fixed end 340 of the torsion spring 34 is fixed to the fixing hole 126e, and the free end 342 is fixed to the locking pin 140. In this way, in the state where the handle grip 100 is in the initial position, the displacement in the winding direction of the torsion spring 34 due to the engagement between the free end 342 of the torsion spring 34 and the engagement pin 140 is maximized. That is, by maximizing the displacement of the torsion spring 34, the resistance force of the accelerator operation and the return force when the accelerator operation is released can be maximized.

  As described above, the urging force when the fixing end 340 of the torsion spring 34 is fixed to the fixing hole 126a is minimized, and the urging force when the fixing end 340 of the torsion spring 34 is fixed to the fixing hole 126e is maximized. Become. The urging force is appropriately changed depending on whether the fixed end 340 is fixed to any one of the fixed holes 126b to 126d between the fixed hole 126a and the fixed hole 126e. The urging force is weakened by fixing on the fixing hole 126a side, and the urging force is increased on fixing on the fixing hole 126e side. By determining which position of the fixing holes 126a to 126e is fixed and fixing the fixing hole, that is, by changing the fixing position, a desired accelerator operation resistance can be obtained.

(Modification)
In the accelerator apparatus 10 according to the first embodiment, it has been described that the support member 12 has a plurality of fixing holes 126 and the yoke holder 14 includes the locking pins 140, but the present invention is not limited to this configuration. Next, with reference to FIG. 5, an accelerator device including a support member 62 and a yoke holder 64 according to a modification will be described. Note that the accelerator device according to the modified example has the same configuration as the configuration of the accelerator device 10 according to the first embodiment unless otherwise specified.

  The yoke holder 64 according to the modification is formed in a substantially short cylindrical shape having a flange 141 on one end face. Two projecting portions 148 projecting with a substantially trapezoidal cross section are formed on the end surface on the side where the flange 141 is formed. Between the two protrusions 148, three fixing holes (second mounting portions) 146 (146a to 146c) which are arranged on a concentric circle with the rotation axis of the accelerator member 11 as the center and formed at a predetermined interval are formed. Have. The fixing hole 146 is for fixing the fixed end 340 of the torsion spring 34.

  The support member 62 according to the modification is formed in a substantially short cylindrical shape having a flange 121 on one end face. Further, a step is formed on the inner peripheral portion of the support member 62. The support member 62 is arranged on a surface of the step facing the yoke holder 64 on a concentric circle centered on the rotation axis of the accelerator member 11 and is formed to protrude at a predetermined interval (first mounting pin). Part) 620 (620a, 620b). The locking pin 620 has a function of fixing the free end 342 of the torsion spring 34. Further, two arcuate rotation stoppers 628 are formed on the end surface 127 opposite to the flange 121 of the short circular portion of the support member 62 so as to protrude from the end surface 127 with the locking pin 620 interposed therebetween. . The rotation stopper 628 restricts the rotation of the yoke holder 64 when the side surface of the rotation stopper 628 contacts the protruding portion 148 of the yoke holder 64.

  In order to minimize the resistance force of the accelerator operation, the fixed end 340 of the torsion spring 34 is fixed to the fixing hole 146a, and the free end 342 is fixed to the locking pin 620a. In this way, in the state where the handle grip 100 is in the initial position, the displacement in the winding direction of the torsion spring 34 due to the engagement between the free end 342 of the torsion spring 34 and the engagement pin 620a is minimized. That is, by minimizing the displacement of the torsion spring 34, the resistance force of the accelerator operation and the return force when the accelerator operation is released can be minimized.

  On the other hand, when the resistance force of the accelerator operation is maximized, as shown in FIG. 5, the fixed end 340 of the torsion spring 34 is fixed to the fixing hole 146c, and the free end 342 is fixed to the locking pin 620b. Thus, in the state where the handle grip 100 is in the initial position, the displacement in the winding direction of the torsion spring 34 due to the engagement between the free end 342 of the torsion spring 34 and the engagement pin 620b is maximized. That is, by maximizing the displacement of the torsion spring 34, the resistance force of the accelerator operation and the return force when the accelerator operation is released can be maximized.

  Further, by changing the fixing between the fixed end 340 of the torsion spring 34 and the fixing holes 146a to 146c and the fixing between the free end 342 and the locking pins 620a and 620b, the desired accelerator operation resistance and the accelerator operation release are changed. You can get the return force of time.

  As described above, the accelerator operating device according to the present embodiment and the modification includes at least one of a fixing hole and a locking pin, and one end of the torsion spring in any one of the plurality of fixing holes. Alternatively, since the other end is attached, the elastic force of the torsion spring (the urging force of the first urging member) can be adjusted depending on the attachment position. For this reason, the resistance force of the accelerator operation and the return force when the accelerator operation is released can be changed to a desired size without changing the parts (parts related to generating the urging force). In other words, by using this accelerator operation device for a plurality of types of vehicles that require different accelerator resistances and return forces, it is possible to share predetermined parts in the accelerator operation device. Therefore, it is not necessary to prepare various types of parts each time the resistance force of the accelerator operation and the return force when the accelerator operation is released are changed. For this reason, useless inventory can be reduced and it is economically favorable.

  Further, by arranging a plurality of fixing holes and / or locking pins on the circumference around the rotation axis of the accelerator member, the torsion spring fixed to the fixing holes and / or the locking pins can be stabilized. Thus, the accelerator operating device can be accommodated, and the biasing force of the torsion spring can be easily adjusted.

  In addition, by fixing one end of both ends of the torsion spring to the fixing hole and fixing the other end to the locking pin, the torsion spring can be easily attached to the accelerator operating device.

  Further, by providing the accelerator operating device with the compression spring, it is possible to generate a resistance force of a desired accelerator operation. In addition, the resistance force of the accelerator operation can be increased by using a compression spring having a long spring diameter or a large number of turns, and conversely, an accelerator operation can be performed by using a compression spring having a short spring diameter or a small number of turns. It is also possible to reduce the resistance force.

  Moreover, since the torsion spring and the compression spring are arranged so as to overlap in the radial direction, the size of the accelerator operating device can be reduced, and the degree of freedom in design can be improved.

  In addition, by providing a fixing hole and / or a locking pin in the yoke holder that supports the yoke provided for detecting the rotational position of the accelerator, a component for adjusting the return force and resistance force of the accelerator is provided. There is no need to provide it separately.

  The present invention is not limited to the above-described embodiment and modification examples (including the configuration described in the drawings). Needless to say, it is possible to appropriately change the above configuration.

  The accelerator operating device has been described as including a torsion spring fixed between the accelerator member and the fixed member. However, the present invention can be applied to any device as long as the two members rotate relatively. Can be applied. For example, the accelerator member is composed of one or more members that rotate in accordance with an accelerator operation, and the fixed member is composed of, for example, one or more members that do not move even when the accelerator member rotates. That is, as in the accelerator operating device according to the present embodiment, the accelerator member includes the handle grip and the yoke holder, and the fixing member includes the sensor, the friction member, the compression spring, the support member, the upper housing, and the lower housing. It is not limited to being configured.

  In the above description, the case where the torsion spring is employed as the first biasing member that biases the accelerator member 11 so as to be in the state before the pivoting state is described. It may be constituted by other members.

  In addition, as described above, a compression spring is employed as the second urging member that generates a resistance force when one member is pressed against the other member by urging one member and the accelerator member rotates. Although the case has been described, the second urging member may be constituted by another member. In particular, in the above, the second biasing member presses the member in the fixed member against the member in the accelerator member by biasing the member in the fixed member, but the second biasing member is a member in the accelerator member. The member in the accelerator member may be pressed against the member in the fixing member by urging.

  In addition, as the first mounting portion or the second mounting portion to which one end or the other end of the first urging member is attached, the case where the first urging member is configured from either the fixing hole or the locking pin has been described. The attachment portion or the second attachment portion may be configured by any one of the fixing hole and the locking pin, or the others. In addition, it is sufficient that at least one of the first mounting portion and the second mounting portion is formed in plural. Further, the place where the first attachment portion or the second attachment portion is provided is not limited to the above. In particular, the first mounting portion may be provided on a housing member that includes an upper housing and a lower housing. Furthermore, the number of the 1st attaching part or the 2nd attaching part in the case of providing two or more is not restricted to the example of the accelerator operating device which concerns on 1st Embodiment and a modification, but is arbitrary. When fixing the end of the torsion spring in the fixing hole, make sure that the end on the side where the end is inserted into the fixing hole is in the same direction as the central axis of the winding and protrudes outward. In the case where the end of the torsion spring is fixed, it is preferable that the end is formed in a U shape so that the end is folded back to the outside of the winding.
