The part is allowed to rotate relatively. Further, both the members can be obtained by restricting the relative movement of the movable body in the circumferential direction with respect to the circular wall by the movable body movement regulation adjusting mechanism and moving the movable body to a region contacting both surfaces of the non-circular wall portion and the circular wall portion. Are engaged with each other, the two shaft portions are in a relative rotation restricted state, and roll rigidity is generated.
In addition, the force that restricts the relative movement of the movable body in the circumferential direction with respect to the circular wall requires only a very small force, and the movable body movement restriction adjusting mechanism can be configured simply.

  Hereinafter, a stabilizer device according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3, a stabilizer device 1 includes a stabilizer 4 including a shaft portion 2 that extends in the width direction of a vehicle (not shown) and extended shaft portions 3 that are respectively extended at both ends of the shaft portion 2. Have. The stabilizer 4 is divided into first and second bars 5 and 6 at the central portion of the shaft portion 2. A bottomed cylindrical member 7 is attached to one end of the first bar 5. The bottomed cylindrical member 7 includes a circular wall portion having a circular cross section (hereinafter referred to as a bottomed cylindrical member circular inner wall portion 8) on the inner peripheral side thereof.

  A lid 9 is placed over the opening of the bottomed cylindrical member 7. The lid 9 is fixed to the bottomed cylindrical member 7 with bolts 10. A hole (reference numeral omitted) is formed at the center of the lid 9, and one end of the second bar 6 is inserted into the circular inner wall 8 of the bottomed cylindrical member through this hole. A cam 12 is coupled to one end of the second bar 6 via a serration 11. The length of the cam 12 is about 1/2 of the depth of the bottomed cylindrical member circular inner wall 8. The tip of the cam 12 substantially reaches the bottom 13 of the bottomed cylindrical member 7, and a bearing 14 is interposed between the outer peripheral portion on the tip side and the circular inner wall 8 of the bottomed cylindrical member 8. As shown in FIG. 3, the outer peripheral portion of the base end portion of the cam 12 is a cam octagon in which eight plane portions 17 (a plurality of plane portions) are connected in the circumferential direction via corner portions 18 to form a regular octagonal cross section. It becomes the outer wall part 20 (non-circular wall part).

A bottomed cylindrical roller holding member 21 is disposed in the bottomed cylindrical member circular inner wall portion 8. As shown in FIGS. 2 and 3, the roller holding member 21 includes a cylindrical roller holding member main body 22 disposed between the circular inner wall 8 of the bottomed tubular member and the cam 12, and a base end of the cam 12. And a bottom part (hereinafter referred to as a roller holding member bottom part 23) in which a hole 23a for inserting the second bar 6 is formed in the center part.
The roller holding member main body 22 has eight holes (reference numerals omitted) formed at equal intervals in the circumferential direction, and one roller 25 (movable body) is disposed in each of the eight holes. As shown in FIGS. 4 and 5, the roller holding member bottom 23 has two plate-like magnetic bodies (hereinafter referred to as FIG. 4) arranged to extend in the radial direction of the roller holding member bottom 23 with a hole 23a therebetween. The upper and lower magnetic bodies are referred to as first and second magnetic bodies 26a and 26b, respectively), and a pair of arc-shaped nonmagnetic materials holding the first and second magnetic bodies 26a and 26b. And a bottom main body plate 27.

As shown in FIGS. 3 and 7, the roller 25 has an outer diameter R1 of the cam octagonal outer wall portion 20 (noncircular wall portion) in the circumferential direction center of the flat surface portion 17 and the bottomed cylindrical member circular inner wall portion 8. The corner 18 of the cam octagonal outer wall 20 that is smaller than the length dimension mx1 (corresponding to the maximum distance between the non-circular wall part and the circular wall part of claim 1). Dimension mn1 (corresponding to the minimum distance dimension between the non-circular wall part and the circular wall part of claim 1) (mx1>R1> mn1). .
By setting the dimensions in this manner, the roller 25 and the bottomed cylindrical member circular inner wall portion when the roller 25 is disposed at the circumferential center portion 17C of the plane portion 17 as shown in FIG. There is a gap G1 between the first bar 8 and the second bar 5 and 6, as will be described later, relative rotation is allowed.
On the other hand, as shown in FIG. 9, when the roller 25 moves to the corner 18 side of the plane portion 17 of the cam octagonal outer wall portion 20, the corner 18 side portion of the cam octagonal outer wall portion 20 and the bottomed cylindrical member Engaged with the circular inner wall portion 8 (this operation is hereinafter referred to as a wedge effect for convenience), whereby the bottomed tubular member 7 and the cam 12 are fixed, and as a result, the first is described later. The second bars 5 and 6 are restricted from relative rotation. The corner 18 side portion of the cam octagonal outer wall portion 20 corresponding to the portion exhibiting the wedge effect and the bottomed cylindrical member circular inner wall portion 8 are collectively referred to as a wedge portion 30 as appropriate.

The roller 25 moves integrally with the rotation of the roller holding member 21. Further, the roller 25 which is an operating body receives a small pulling force in the center direction of the cam octagonal outer wall portion 20 which is a non-circular wall portion by a spring means (not shown), and a gap G1 is always generated. As a specific structure, a small-diameter portion having a predetermined width is provided in the center of each roller 25 in FIG. 2 in the axial direction, and a C-shaped reduced diameter ring spring (spring means) having substantially the same diameter as the roller holding member main body 22 is used. What is necessary is just to set it as the structure hooked on the outer side of a small diameter part.
The roller 25 and the roller holding member 21 are integrated with the rotation of the cam 12 (and hence the second bar 6) when the roller 25 is disposed, for example, in the circumferential center portion 17C of the flat portion 17. (I.e. both rotate at the same speed).
In the present embodiment, as will be described later, the electromagnetic force generated by the first and second solenoids 32a and 32b suppresses the interlocking of the roller holding member 21 with the cam 12 (and consequently the second bar 6). 25 is moved from the circumferential center portion 17C of the flat surface portion 17 to the corner portion 18 side, and the wedge portion 30 exhibits a wedge effect to restrict the relative rotation of the first and second bars 5 and 6, and the stabilizer 4 ( The first and second bars 5 and 6) are made to exhibit torsional rigidity.
The force for moving the roller 25 to the corner 18 side at this time can be overcome by the above-described small force spring means (not shown) and moved to a position where the roller 25 contacts both the flat surface portion 17 and the circular inner wall portion 8. Good, small power is good.

A solenoid holding member 35 is fitted and attached to the annular step portion 33 provided on the inner peripheral side of the lid 9. The solenoid holding member 35 includes a cylindrical solenoid holding member main body 36 having a predetermined width, and a solenoid holding member support portion 37 connected to one end of the solenoid holding member main body 36 and having a smaller outer diameter than the solenoid holding member main body 36. The solenoid holding member support portion 37 is fitted to the annular step portion 33.
As shown in FIGS. 2 and 6, the solenoid holding member main body 36 has two holes (reference numerals omitted) that open on the opposite side of the solenoid holding member support portion 37 with the center of the shaft in between. . The two holes are respectively inserted with solenoids (hereinafter, as appropriate, FIG. 2, the upper solenoid is referred to as the first solenoid 32a, and the lower solenoid is referred to as the second solenoid 32b). The first and second solenoids 32a and 32b are held by the solenoid holding member main body 36 by an insulating member 38 provided so as to cover the hole. A bearing 39 for rotatably supporting the second bar 6 is interposed on the inner peripheral side of the solenoid holding member support portion 37.
In the present embodiment, the first and second solenoids 32a and 32b, the first and second magnetic bodies 26a and 26b, and the wedge part 30 constitute a movable body movement regulation adjusting mechanism.

  A current supply means 40 such as a battery is connected to the first and second solenoids 32 a and 32 b via a controller 41. Connected to the controller 41 are a steering data detection means 42 for detecting steering data including a steering wheel operation amount and an operation speed that affect the roll behavior, a vehicle speed detection means 44 for detecting a vehicle speed, and a manual switch 43. Based on the detection result of the steering data detecting means 42 (steering data) and the detection result of the vehicle speed detecting means 44 for detecting the vehicle speed or the presence or absence of an operation signal from the manual switch 43, the controller 41 The current supply to 32a and 32b is adjusted. Here, the small steering data means that the steering wheel operation amount and the operating speed are small, and corresponds to, for example, the case where the steering wheel is slowly turned (including the case where the steering wheel is not turned as in the case of straight running). Further, the large steering data means that the steering wheel operation amount and the operating speed are large, and corresponds to, for example, the case where the steering wheel is fully or quickly turned.

As the steering data detection means 42, for example, a steering angle sensor is used. When it is predicted that the roll behavior generated when the steering data (steering operation amount, operation speed) detected by the steering data detection means 42 is small when the vehicle is running straight without steering operation, the controller 41 is the first, The second solenoids 32a and 32b are not energized.
In this state, as shown in FIG. 7, the roller 25 is disposed at the circumferential center portion 17C of the flat portion 17, and the first and second bars 5 and 6 can freely rotate.
As shown in FIG. 8, the state in which the first and second solenoids 32a and 32b face the first and second magnetic bodies 26a and 26b is 0 ° in the roll angle of the vehicle in the present embodiment. It corresponds to a neutral position, and for convenience, this state is referred to as a neutral state.

  Moreover, it is predicted that the roll behavior generated when the steering data (handle operation amount, operation speed) detected by the steering data detection means 42 is large, such as when the steering wheel is fully increased (because of an increase in the roll amount), is large. When the operation signal is input from the manual switch 43, the controller 41 energizes the first and second solenoids 32a and 32b, and the first and second bars 5 as described later. , 6 is restricted, the stabilizer 4 (first and second bars 5, 6) exhibits torsional rigidity, the roll behavior is suppressed, and riding comfort and driving stability are improved. .

The operation of the stabilizer device 1 configured as described above will be described below.
When the steering wheel is slowly moved in one direction or when the vehicle speed is low, the roll behavior generated in the vehicle is small. In this case, the value of the steering data detected by the steering data detection means 42 and the value of the detection data detected by the vehicle speed detection means 44 are also small. And the controller 41 which received the detection data from the steering data detection means 42 and the vehicle speed detection means 44 does not supply electricity to the first and second solenoids 32a and 32b. For this reason, a gap G1 shown in FIG. 7 is secured between the roller 25 and the bottomed cylindrical member circular inner wall portion 8, and the first and second bars 5 and 6 correspond to the roll behavior accompanying the handle operation. Relative rotation is allowed. Therefore, at this time, when the rotational force accompanying the roll behavior acts on the second bar 6, the roller holding member 21 (roller 25) maintained in the positional relationship of FIG. ) And rotate together.
As described above, when it is predicted that the roll behavior generated in the vehicle by slowly turning the steering wheel is small, the roller 25 does not engage with the bottomed tubular member 7 and the cam 12, so that the torsional rigidity is generated in the stabilizer 4. do not do.

Further, when the vehicle speed is high, it is predicted that a large roll behavior will occur in the vehicle by turning the steering wheel fast, but the steering data value from the steering data detecting means 42 is large due to such a rapid steering operation. If the controller 41 receives an operation signal from the manual switch 43 in response to a quick steering operation, the controller 41 supplies current to the first and second solenoids 32a and 32b. Therefore, the first and second solenoids 32a and 32b generate a magnetic field, and when the neutral state of FIG. 8 is reached, an electromagnetic force is applied to the first and second magnetic bodies 26a and 26b. Then, the displacement of the second magnetic bodies 26a, 26b and the roller holding member 21 (roller 25) is suppressed (the roller 25 starts to move relative to the bottomed tubular member 7). That is, the electromagnetic force functions to cause the first and second magnetic bodies 26a and 26b to remain at the positions of the first and second magnetic bodies 26a and 26b.
When the rotational force acts on the second bar 6 due to the roll behavior accompanying the handle operation, the second bar 6 (cam 12) is in a state where the displacement of the roller holding member 21 (roller 25) is suppressed by the electromagnetic force. Turns slightly. For this reason, the roller 25 moves from the circumferential center portion 17C of the plane portion 17 to the corner portion 18 side, and engages with the bottomed tubular member 7 and the cam 12 due to the wedge effect of the wedge portion 30. Accordingly, the relative rotation of the first and second bars 5 and 6 is restricted, the torsional rigidity is generated in the stabilizer 4, the roll rigidity of the vehicle body is increased, and the roll behavior is suppressed.

  When the roll behavior is released by the roll behavior suppression operation, the engagement of the roller 25 with the bottomed tubular member 7 and the cam 12 is released by a spring means (not shown), and the roller 25 returns to the state shown in FIG. When the first bar 5 and the second bar 6 try to rotate relative to each other again, the roller 25 engages with the bottomed tubular member 7 and the cam 12 again.

When the handle is moved slowly in one direction (the roll amount is small) and the handle is operated suddenly in the same direction, the first and second magnetic bodies 26a and 26b and the first and second solenoids 32a, As shown in FIG. 10, the positional relationship of 32b is in a state where it does not face each other, and the magnetic field generated by the first and second solenoids 32a and 32b has little effect on the first and second magnetic bodies 26a and 26b. Become.
As described above, when the handle is suddenly operated in one direction and a sudden handle operation is performed in the same direction, when the first and second solenoids 32a and 32b are energized, the bottomed cylindrical shape at that time The roller 25 does not engage with the member 7 and the cam 12. Thereafter, when the handle is moved in the opposite direction, the first and second magnetic bodies 26a and 26b and the first and second solenoids 32a and 32b are in the positional relationship shown in FIG. As a result, torsional rigidity is generated in the stabilizer 4 and the roll behavior of the vehicle is suppressed.

  Further, as described above, since the roller 25 is engaged with the bottomed tubular member 7 and the cam 12 only near the neutral position of the first bar 5 and the second bar 6, the vehicle rolls during normal traveling. Will not be left in the state.

In the above embodiment, the bottomed cylindrical member 7 includes the bottomed cylindrical member circular inner wall portion 8 (circular wall portion) having a circular cross section on the inner peripheral side, and the cam having a regular octagonal cross section on the outer peripheral portion of the cam 12. Although the case where the octagonal outer wall portion 20 (non-circular wall portion) is provided is taken as an example, the present invention is not limited to this. For example, as shown in FIG. 11, a polygonal wall portion 51 having a regular octagonal cross section may be provided on the inner periphery of the bottomed tubular member 7, and a circular wall portion 52 may be provided on the outer peripheral portion of the cam 12. In this case, the roller 25 is pulled toward the bottomed tubular member 7 by a spring means (not shown).
In the case of the example shown in FIG. 11, the circumferential center portion 53C of the flat surface portion 53 of the polygonal wall portion 51 provided on the inner peripheral portion of the bottomed tubular member 7 and the circular wall portion 52 of the outer peripheral portion of the cam 12 The wedge part 30A is configured.

Next, a stabilizer device 1A according to a second embodiment of the present invention will be described with reference to FIGS. This stabilizer device 1A is mainly different from the first embodiment in the items (1) to (6).
(1) On the inner peripheral side of the lid 9, a neutral position of the second bar 6 [a position where the roll angle of the vehicle is 0 °. In the present embodiment, in the neutral position, the roller 25 is disposed at the position shown in FIG. ] Is provided, and the sensor holding member 62 for fixing the position sensor 61 is fastened to the lid 9 together with the bolt 10.
(2) In order to detect the neutral position by the position sensor 61, the magnet 63 is provided in a portion corresponding to the position sensor 61 of the second bar 6.
(3) One solenoid (referred to as a large-diameter solenoid 64 for convenience) is provided in place of the first and second solenoids 32a and 32b.
(4) An annular hole 65 is formed in the solenoid holding member main body 36 instead of the two holes provided in the first embodiment, and the large-diameter solenoid 64 is inserted into the annular hole 65 to close the annular hole 65. The large-diameter solenoid 64 is held in the solenoid holding member main body 36 by the annular insulating material 66 arranged as described above.
(5) The roller holding member bottom 23 of the first embodiment is composed of the first and second magnetic bodies 26a and 26b and the bottom main body plate 27 of a nonmagnetic material. Thus, a roller holding member bottom portion (hereinafter referred to as a roller holding member magnetic bottom portion 67) made entirely of a magnetic material is provided.
(6) The controller 41 controls the energization of the large-diameter solenoid 64 using the detection signal from the position sensor 61.

  In the second embodiment, the position sensor 61 outputs a neutral position detection signal to the controller 41 when facing the magnet 63. When the controller 41 receives an input of the neutral position detection signal and receives an input of steering data having a large value from the steering data detection means 42 in addition to this, the controller 41 energizes the large-diameter solenoid 64, and the first and first The relative rotation of the two bars 5 and 6 is restricted. Further, the controller 41 does not supply a current to the large-diameter solenoid 64 when it receives an input of a neutral position detection signal and receives an input of steering data having a small value from the steering data detection means 42.

In the stabilizer device 1A configured as described above, a bottomed cylindrical member is formed in the same manner as in the first embodiment due to eddy current loss with respect to the roller holding member 21 (roller holding member bottom 67) by the large-diameter solenoid 64. 7 and the cam 12 are engaged with each other, whereby the stabilizer 4 can exhibit a large torsional rigidity, and the roll behavior can be suppressed.
Further, if the steering wheel is kept fast during the return process of the steering operation, the position sensor 61 detects the magnet 63 attached to the second bar 6 of the stabilizer 4 when the stabilizer 4 returns to the neutral position, and the neutral position is detected. A signal is output to the controller 41. At this time, the controller 41 receives the steering data having a large value from the steering data detecting means 42 and energizes the large-diameter solenoid 64 due to the fact that the steering wheel is fastened, thereby generating torsional rigidity in the stabilizer 4. The roll rigidity generated in the vehicle becomes high and the roll behavior is suppressed.

  Further, when the handle 4 is slowly turned in the opposite direction when the stabilizer 4 returns to the neutral position, the position sensor 61 outputs a neutral position detection signal to the controller 41. However, the controller 41 receives steering data having a small value from the steering data detection means 42 and does not supply current to the large-diameter solenoid 64. The first and second bars 5 and 6 are allowed to rotate relative to each other. In this case, the roll rigidity of the vehicle generated in accordance with the steering operation is determined only by the disparity of each wheel (not shown) provided separately, and is kept low.

The roller holding member bottom 23 and the magnetic bodies 26a and 26b of the first embodiment may be formed as an integral disk shape made of a hysteresis material.
In each of the above-described embodiments, the case where the movable body is the roller 25 is taken as an example. However, instead of this, the movable body may be formed of a sphere.
Moreover, in each said embodiment, although the case where it was an octagonal shape by making a non-circular wall part into a polygonal wall part was taken as an example, other shapes, such as a hexagon, may be sufficient. Further, the corners are not necessarily required, and the corners may be rounded. As shown in FIG. 5, there is a portion having a wide distance from the circular wall and portions formed on both sides of the distance and gradually decreasing the distance. If it is a circular wall, a circular cross-section member such as a roller is in a wide distance when it is not restricted by movement and does not come into contact with the circular wall. It is sufficient if the structure is such that the relative rotation is stopped by moving to the part. For this, a structure of what is generally called a torque diode can be used.
