Japanese Patent No. 6081737

  By the way, if the shaft rattles in the axial direction, there are concerns such as deterioration of the operational feeling when the shaft is rotated and generation of abnormal noise due to contact of the shaft with the housing.

  An object of the present invention is to provide a reaction force presentation device that can reduce shakiness in the axial direction of a shaft.

  In the reaction force presentation device that solves the above problem, when the shaft is operated to rotate, the rotation shaft rotates via a gear mechanism for reduction, and the biasing member that interlocks with the rotation shaft causes the shaft to rotate. An operation reaction force is applied, and a backlash in the axial direction of the shaft is suppressed between a bearing that rotatably supports the shaft and a seating surface that supports the bearing. A suppression member is provided.

  According to this configuration, even if there is a gap between components in the axial direction of the shaft, the shaft can be securely assembled to the housing by the rattling suppression member provided between the bearing and the seating surface. Become. Therefore, it is possible to alleviate rattling in the axial direction of the shaft.

  In the reaction force presentation device, it is preferable that the shaft and the rotation shaft have a biaxial structure in which the rotation axes are arranged in parallel, and the gear mechanism is a helical gear. According to this configuration, when a helical gear is used for the gear mechanism, there is a concern that the separation load of the helical gear is input to the shaft when the shaft is rotated, and the shaft may rattle in the axial direction. Since this is provided, it is possible to alleviate this rattling. In addition, since a helical gear capable of transmitting a sufficient torque even with a small size is used, the size of the reaction force presentation device can be reduced. Furthermore, it is possible to provide a reaction force presentation device having a simple structure in which two axes of the shaft and the rotation shaft are arranged in parallel.

  In the reaction force presentation device, the biasing member is a coil spring in which the rotation shaft is inserted into an inner diameter hole, and when the shaft rotates, the rotation of the rotation shaft causes the coil spring to rotate. It is preferable that an operation reaction force is applied to the shaft by being twisted. According to this configuration, it is possible to apply an operation reaction force to the shaft with a simple configuration using a coil spring.

  In the reaction force presentation device, it is preferable that the rattling suppression member is a disc spring that is loosely fitted to the shaft and can generate an urging force in an axial direction of the shaft. According to this configuration, it is possible to reduce shakiness in the axial direction of the shaft with a simple configuration using a disc spring.

  In the reaction force presenting device, one of the tightening allowances of the bearing with respect to the shaft and the housing that accommodates at least a part of the shaft in a rotatable manner is an interference fit, and the other is a clearance fit or an intermediate fit. Preferably it is. According to this structure, even if a bearing is interposed between the housing and the shaft, the shaft can be easily moved in the axial direction. Therefore, it is possible to make it easier to reduce the shakiness in the axial direction of the shaft by the shakiness suppressing member.

  In the reaction force presentation device, it is preferable that a width adjusting member for adjusting a width of a storage portion in which the rattling suppressing member is stored is attached between the bearing and the seating surface. According to this configuration, the storage width of the rattling suppressing member can be adjusted as appropriate by the width adjusting member, so that variations in the storage width can be kept within a certain range. Therefore, since it becomes possible to assemble the rattling suppression member into the storage portion in a state where the function of the rattling suppression member is sufficiently satisfied, it is more advantageous for suppressing the axial rattling of the shaft. Become.

  According to the present invention, in the reaction force presentation device, rattling in the axial direction of the shaft can be reduced.

The stopper portion 37 is formed in a protruding shape and is inserted into the guide groove 38. The guide groove 38 is formed in an arc shape along a path along which the stopper portion 37 moves when the rotation shaft 14 rotates. The stopper portion 37 is disposed so as to be positioned at the center of the path of the guide groove 38 when the shaft 3 takes the neutral position of rotation.

  The reaction force presentation device 1 includes a damper mechanism 39 that can apply an operation load to the shaft 3 that is rotated. The damper mechanism 39 is preferably a rotary damper, for example. The damper mechanism 39 is attached and fixed to the shaft 3 outside the housing 2 such that the end of the shaft 3 is inserted into the central through hole 41 of the substantially disc-shaped main body 40. The damper mechanism 39 is attached to the side wall 4 a of the housing body 4 by a plurality of (two in this example) fastening portions 42. The damper mechanism 39 alleviates the overshoot that excessively turns to the opposite side when the shaft 3 returns to the neutral position.

  The reaction force presentation device 1 includes a rotation angle detection unit 45 that detects the rotation angle of the shaft 3. The rotation angle detection unit 45 is a so-called steering angle sensor, and is attached to the outside of the housing 2 via a bracket 46.

The external cover 56 is positioned on the housing 2 by a plurality of positioning portions 58 and then attached and fixed to the housing 2 by a snap fit portion 57.

  As shown in FIG. 5, when the shaft 3 is rotated in one direction (the direction of arrow A <b> 1 in FIG. 5), the rotation is decelerated by the gear mechanism 13 and transmitted to the rotation shaft 14. Rotates in one direction (the direction of arrow B1 in FIG. 5). At this time, the guide portion 31 pushes up the other end 23b of the coil spring 23, and one end 23a of the coil spring 23 comes into contact with the receiving portion 33, and the movement of the one end 23a is stopped. As a result, the coil spring 23 is compressed in the direction of the arrow B <b> 1 by pushing up the guide portion 31, and the biasing force generated at this time is applied as an operation reaction force to the shaft 3.

  When the shaft 3 is rotated in one direction (the direction of arrow A1 in FIG. 5), a load in the opposite direction is applied to the shaft 3 by the damper mechanism 39. Thus, when the shaft 3 is rotated in the direction of the arrow A1 in the drawing, the operation reaction force in the opposite direction to the direction of the arrow A1 in the drawing is caused by the operation of the coil spring 23 and the damper mechanism 39. To be granted. The shaft 3 is allowed to rotate until the stopper portion 37 comes into contact with one end edge 38a of the guide groove 38.

  As shown in FIG. 6, when the shaft 3 is rotated in the other direction (the direction of arrow A <b> 2 in FIG. 6), the rotation is decelerated by the gear mechanism 13 and transmitted to the rotating shaft 14. Rotates in the other direction (the direction of arrow B2 in FIG. 6). At this time, the guide portion 31 pushes up the one end 23a of the coil spring 23, and the other end 23b of the coil spring 23 comes into contact with the receiving portion 33 so that the movement of the other end 23b is stopped. As a result, the coil spring 23 is compressed in the direction of the arrow B <b> 2 by pushing up the guide portion 31, and the urging force generated at this time is applied as an operation reaction force to the shaft 3.

  When the shaft 3 is rotated in the other direction (the direction of arrow A2 in FIG. 6), a load in the opposite direction is applied to the shaft 3 by the damper mechanism 39. As described above, when the shaft 3 is rotated in the direction of the arrow A2 in the drawing, the operation reaction force in the opposite direction to the direction of the arrow A2 in the drawing is caused by the operation of the coil spring 23 and the damper mechanism 39. To be granted. The shaft 3 is allowed to rotate until the stopper portion 37 contacts the other end edge 38b of the guide groove 38.

  As shown in FIG. 7, between the bearing 11 that rotatably supports the shaft 3 and the seating surface 60 that can support the bearing 11, “in the axial direction of the shaft 3 (X-axis direction in FIG. 7)”. A rattling suppressing member 61 is provided that suppresses “rattle”. The rattling suppressing member 61 suppresses rattling in the axial direction of the shaft 3 by pressing the bearing 11 along the axial direction of the shaft 3 (the arrow X1 direction in FIG. 7).

  The rattling suppressing member 61 of this example is a disc spring 62 that can generate a biasing force in the axial direction of the shaft 3. The disc spring 62 is loosely fitted to the shaft 3 by passing the shaft 3 through the hole 63 in the middle. The disc spring 62 is stored in a storage portion 64 formed of a space between the bearing 11 and the seat surface 60. The seat surface 60 is a bearing seat surface that can support the bearing 11, and is formed on the inner wall surface of the housing 2. The disc spring 62 has one surface in contact with the seat surface 60 (point contact) and the other surface in contact with the outer ring 11 a of the bearing 11 (point contact). The disc spring 62 relieves the shakiness in the axial direction of the shaft 3 due to the separation load of the gear mechanism 13 (helical gear) by its own urging force. The bearing 15 urged in the axial direction of the shaft 3 by the disc spring 62 is positioned by a stepped portion 66 recessed in the outer periphery of the shaft 3.

Next, the operation and effect of the reaction force presentation device 1 according to the embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 7, since the disc spring 62 is provided between the bearing 11 and the seating surface 60 (bearing seating surface), the axial direction of the shaft 3 (the direction of the arrow X1 in FIG. 7) by the biasing force of the disc spring 62. It becomes possible to hold down. Therefore, it is possible to alleviate the shakiness in the axial direction of the shaft 3 due to the separation load of the gear mechanism 13 (helical gear). Moreover, if the shakiness of the shaft 3 in the axial direction is alleviated, the contact sound between the housing 2 and the bearing 11 can be suppressed to a low level.

  In the case of this example, even if there is a gap between parts (for example, the housing 2 and the bearing 11) in the axial direction of the shaft 3, the disc spring 62 provided between the bearing 11 and the seating surface 60 causes the shaft to move. 3 can be firmly attached to the housing 2. Therefore, rattling in the axial direction of the shaft 3 can be reduced.

  The shaft 3 and the rotating shaft 14 have a biaxial structure in which the rotating shaft centers L1 and L2 are arranged in parallel, and the gear mechanism 13 is a helical gear. By the way, if a helical gear is used for the gear mechanism 13, there is a concern that the separation load of the helical gear is input to the shaft 3 when the shaft 3 is rotated, and the shaft 3 rattles in the axial direction. However, in the case of this example, since the disc spring 62 is provided between the bearing 11 and the seat surface 60, this rattling can be alleviated. Moreover, since the helical gear which can transmit sufficient torque is used even if it is small, the device size of the reaction force presentation device 1 can be reduced. Furthermore, the reaction force presentation device 1 having a simple structure in which the two axes of the shaft 3 and the rotation shaft 14 are arranged in parallel can be provided.

  The urging member 21 is a coil spring 23 in which the rotation shaft 14 is inserted into the inner diameter hole 22. Therefore, an operational reaction force can be applied to the shaft 3 with a simple configuration using the coil spring 23.

The rattling suppressing member 61 is a disc spring 62. Therefore, the shakiness of the shaft 3 in the axial direction can be reduced by a simple configuration using the disc spring 62.
In the case of this example, rattling is suppressed between the bearing 15 and the housing 2 (lid portion 5) while suppressing rattling in the axial direction of the rotation shaft 14 (X-axis direction in FIG. 2 and the like). A member 65 (see FIG. 2) is provided. The rattling suppressing member 65 is preferably a disc spring while taking the same arrangement conditions as the rattling suppressing member 61. Therefore, not only the shakiness of the shaft 3 in the axial direction can be suppressed, but also the shakiness of the rotating shaft 14 in the axial direction can be reduced.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIG. In addition, 2nd Embodiment is an Example which changed the attachment structure of the bearing 11. FIG. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and only different parts are described in detail.

  As shown in FIG. 8, one of the tightening allowances E of the bearing 11 with respect to the housing 2 and the shaft 3 is a clearance fit, and the other is an interference fit or an intermediate fit. In this example, a clearance fit is provided between the outer ring 11a of the bearing 11 and the housing 2, and an interference fit or intermediate fit is provided between the inner ring 11b of the bearing 11 and the shaft 3. In this case, the shaft 3 and the bearing 11 are integrally slidable in the axial direction of the shaft 3 (the direction of the arrow X1 in FIG. 8), and the shakiness in the axial direction of the shaft 3 is easily reduced.

  In the case of this example, one of the interference E between the housing 2 and the bearing 11 and the interference E between the bearing 11 and the shaft 3 is a clearance fit, and the other is an interference fit or an intermediate fit. For this reason, even if the bearing 11 is interposed between the housing 2 and the shaft 3, the shaft 3 can be easily moved in the axial direction with respect to the housing 2. It becomes possible to obtain the rattling suppression effect more easily. Therefore, the shakiness of the shaft 3 in the axial direction can be further alleviated.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. In addition, 2nd Embodiment is an Example which enabled adjustment of the width | variety of the storage part 64 of the disc spring 62 of 1st and 2nd embodiment. Therefore, the third embodiment will be described in detail only for the parts different from the first embodiment.

  As shown in FIG. 9, a width for adjusting the width (storage width W) of the storage portion 64 in which the rattling suppressing member 61 (the disc spring 62 in this example) is stored is provided between the bearing 11 and the seat surface 60. An adjustment member 70 is attached. The width adjusting member 70 is preferably a spacer 71, for example. By the way, in order to set the disc spring 62 from which a high load can be obtained, it is necessary to keep the variation in the width of the storage portion 64 (storage width W) within a certain range. Therefore, in this example, the storage width W of the disc spring 62 in the storage part 64 can be adjusted by attaching the width adjusting member 70 to the storage part 64. The storage width W is a storage space for the disc spring 62 in the axial direction of the shaft 3.

  In the case of this example, when assembling the disc spring 62 to the storage portion 64, the spacers 71 having different thicknesses are selected and attached in accordance with the gap W 'between the bearing 11 and the seating surface 60. Specifically, when the gap W ′ is large, the spacer 71 having a large thickness is assembled, and when the gap W ′ is small, the spacer 71 having a small thickness is assembled. In this way, the storage width W of the disc spring 62 can be adjusted as appropriate, so that the high load disc spring 62 can be set regardless of the size of the gap W ′.
