In this cam path 42, can assert and utilize lock(ing) bolt 32 to make steering shaft 1 become the zone of lock-out state, position deviation owing to generations such as vibrations in considering to travel is inevitable, also must consider the rigidity of lock(ing) bolt 32 and steering shaft 1, be set at the height (engaging surplus) that to keep lock-out state reliably.In addition, can regard as the zone of released state, because vibration waits the position deviation of generation, be set at the height (amount of retreating) that engaging protuberance 33 does not enter engaging recessed part 2 really in must considering to travel.
For this reason, except described condition, also comprise the inertia action after the action that stops electro-motor 45 in the present embodiment, the abutting part that will stop back swing pinion 47 is not set at ' locked ' zone with the lowest range of restrictions 18 butts of housing 10.In addition, the 2nd extension is provided with the 42b of portion extends to the height that can satisfy described condition, comprise the inertia action after stopping electro-motor 45 moves, do not set the described the 3rd at the abutting part that stops back swing pinion 47 and extend the 42c of portion is set, extend to be provided with the 3rd and be set at the release zone in the 42c of portion with the lowest range of restrictions 18 butts of housing 10.Have again,, form described teat 43 as the mobile holdout device that stops cam follower wheel 54 in cam path 42, to slide extending the boundary member that the 42b of portion, 42c are set as the 2nd and the 3rd of the start position in release zone.Also have, the 3rd extends the 42c of portion is set, and constitute vertical width than other extensions the 42a of portion, 42b to be set big based on the formation that is provided with described teat 43.In addition, can form following formation based on this teat 43, utilizing spring 28 application of forces so that in the cam member 37 that the locking side enters, cam follower wheel 54 can not be crossed teat 43 and slides to latched position one side from unlocked position under the vibration under steam, slides to latched position one side from unlocked position thereby can cross teat 43 by the propulsive effort that applies electro-motor 45.
Next, specify about the operating portion 53 of swing pinion 47 and the portion of bearing 64 of movable link 61.
These operating portions 53 and bear the link gear that portion 64 is configured for making movable link 61 to rotate with swing pinion 47 interlocks.They as shown in Figure 3, align with the state of a mutual end butt and to form roughly C word shape, between the mutual other end, form the play P (about 18 degree in the present embodiment) of predetermined distance, so form the circular shape that constitutes by a part that with the same point is the annulus at center respectively.Thereby the formation that forms is that if make electro-motor 45 actions, then swing pinion 47 rotations are to rotate the needed delay time of distance of its play P movable link 61 interlock rotations.
Next, specify about being configured in magnet 62 on the movable link 61 and the magnetic pickup device 68A~68C that is configured on the substrate 65.
At first, in the present embodiment, as shown in figure 11, utilize the 1st main magnetic pickup device 68A to detect the operating position of lock(ing) bolts 32 via movable link 61, swing pinion 47 and cam member 37, promptly detect be in ' locked ' zone, move, or in the release zone mobile both sides.In addition, whether the engaging protuberance 33 that utilizes the 2nd auxiliary magnetic pickup device 68B to detect lock(ing) bolt 32 is the state that the open end from the engaging recessed part 2 of steering shaft 1 breaks away from fully.Have again, utilize the 2nd the 3rd auxiliary magnetic pickup device 68C, detect lock(ing) bolt 32 and whether in the release zone, move.Thereby, can constitute, though any one et out of order of magnetic pickup device 68A~68C, also can be enough other 2 detect lock(ing) bolt 32 reliably and whether move to release zone one side.Have again, also can constitute, utilize magnetic pickup device 68A~68C, can detect lock(ing) bolt 32 and whether move to ' locked ' zone one side., if consider that the safety of running car is the 1st, it is the safest that then lock(ing) bolt 32 is positioned at the state in release zone, and can't say in other zones and can guarantee safety reliably, thereby, form the formation of detection release side in the present embodiment.
And, when operating portion 53 and bear when not having play P between the portion 64, comprise that the movable link 61 of magnet 62 rotates in the scope identical with the slewing area of swing pinion 47.Under this condition, utilize the 1st magnetic pickup device 68A to detect any one that lock(ing) bolt is positioned at ' locked ' zone and release zone, at first be positioned under the state of locking side end at swing pinion 47, magnet 62 is set at the scope amount (with reference to Figure 12 (A)) that an end 62a extends ' locked ' zone to the locking side again from the 1st magnetic pickup device 68A.Thereby movable link 61 rotates to the release side, and the time point that an end 62a of magnet 62 surpasses the 1st magnetic pickup device 68A becomes as the locking on ' locked ' zone border judges the position.Equally, be positioned at swing pinion 47 under the state of release side end, magnet 62 is set at other end 62b extends the release zone again to the release side from the 1st magnetic pickup device 68A scope amount (with reference to Figure 13 (A)).Thereby movable link 61 rotates to the locking side, and the time point that the other end 62b of magnet 62 surpasses the 1st magnetic pickup device 68A becomes as the release of release zone boundary judges the position.For this reason, configuration extends to the magnet 62 of the C word shape of other end 62b from an end 62a on movable link 61, so that become such desired location.
Then, swing pinion 47 is during from locking side direction release side shifting, sets all to be positioned at the release zone so that be accompanied by the detection error limit in the magnetic field of magnet 62 delay time.And, at operating portion 53 and bear between the portion 64 and to form the play P that is equivalent to this delay time.
Consequently, when swing pinion 47 releases rotations (action), set and utilize the 1st magnetic pickup device 68A to detect the 1st release detection position that swing pinion 47 has rotated to release zone (position).Equally, when swing pinion 47 locking rotations, set and utilize the 1st magnetic pickup device 68A to detect the 2nd release detection position that swing pinion 47 has broken away from the release zone.And, set the 2nd release detection position for and more be positioned at the locking side than the 1st release detection position.In the present embodiment,, set that the 1st release detection position is positioned at the release side, the 2nd release detection position is positioned at the locking side for to judge that as the release of release zone boundary the position is a benchmark.And described teat 43 is between the 1st release detection position and the 2nd release detection position.
In addition, when swing pinion 47 locking rotations, set and utilize the 1st magnetic pickup device 68A to detect the 1st lock-in detection position that swing pinion 47 has rotated to ' locked ' zone.Equally, when swing pinion 47 releases rotation, set and utilize the 1st magnetic pickup device 68A to detect the 2nd lock-in detection position that swing pinion 47 has broken away from ' locked ' zone.And, set the 2nd lock-in detection position for and more be positioned at the release side than the 1st lock-in detection position.In the present embodiment,, set that the 1st lock-in detection position is positioned at the locking side, the 2nd lock-in detection position is positioned at the release side for to judge that as the locking on ' locked ' zone border the position is a benchmark.
On the other hand, to have slided into the 1st and the 2nd position of extending the boundary member that the 42a of portion, 42b are set be can judge whether engaging protuberance 33 enters engaging recessed part 2, be used to judge that the accurate release of state of comparison safety of thinking that does not enter fully judges the position to gear flower wheel 54.In addition, in the movable link of having set based on detection delay time of play P 61, the detection position when locking side direction release side is rotated more is positioned at the release side than the detection position when release side direction locking side is rotated.
For this reason, the 2nd magnetic pickup device 68B sets for, and the 3rd detection position during from the rotation of release side direction locking side comprises the detection error limit, judges that with described accurate release the position is that benchmark is positioned at the release side.Thereby the formation of formation is to utilize the 2nd magnetic pickup device 68B can judge whether lock(ing) bolt 32 moves to think roughly the position of safety.
In addition, the formation of the 3rd magnetic pickup device 68C formation is whether to be positioned at the release zone at the position probing lock(ing) bolt 32 different with the 1st magnetic pickup device 68A.And,, set detection position when locking side direction release side is rotated for and comprise and detect error limit, judge that with described release the position is that benchmark is positioned at the release side for having based on for the movable link 61 of detection delay time of play P.Detection position during in addition, from the rotation of release side direction locking side comprises the detection error limit, judges that with described release the position is that benchmark is positioned at the locking side.Thereby,, also can detect lock(ing) bolt 32 reliably and be positioned at and think certain safe release zone even during the 1st magnetic pickup device 68A et out of order.
Next, release action and the lock out action about described blocking device describes.
Make described lock(ing) bolt 32 become released state from lock-out state, under the lock-out state shown in Fig. 2 (A), electro-motor 45 is just changeed driving.So, as shown in Figure 3, swing pinion 47 is rotated counterclockwise via worm screw 46, it is mobile on one side in cam path 42 slips or rotation on one side to be positioned near the cam follower wheel in cam path 42 lower ends 54., because cam follower wheel 54 is positioned at the pod 51 of swing pinion 47, can not along the circumferential direction move, therefore, along with the rotation of swing pinion 47, lock(ing) bolt 32 direction that begins to draw back moves.
When this, when cam follower wheel 54 extends when the 42a of portion being set moving along the 1st of cam path 42, lock(ing) bolt 32 retreats more lentamente from latched position.Thereby the engaging protuberance 33 that can increase lock(ing) bolt 32 is extracted load when the engaging recessed part 2 of steering shaft 1 is extracted.Therefore, steering shaft 1 applied turn to (cutting り) moment, can under the state of the inner face of engaging recessed part 2 and the crimped outside that engages protuberance 33, also extract lock(ing) bolt 32 reliably according to ぇ.In addition, can abolish and be used to increase the reducing gear of extracting load etc., can make electro-motor 45 miniaturizations simultaneously.Consequently can seek the miniaturization of blocking device single-piece.
