Description

  The present invention relates to a vehicle steering apparatus having a mechanism for adjusting and locking the position of a steering column that rotatably supports a steering shaft.

  Various types of steering devices for vehicles have been proposed that include an adjustment mechanism that adjusts the position of the steering column (steering position) relative to the vehicle in accordance with the physique and driving posture of the driver. For example, in Patent Document 1, as an adjustment mechanism for adjusting such a steering position, a steering position in a telescopic direction in which the axis of the steering shaft extends, that is, a telescopic mechanism for adjusting the telescopic position, and a steering in a tilt direction orthogonal to the telescopic direction are disclosed. There is disclosed a vehicle steering apparatus equipped with a tilt mechanism for adjusting a position, that is, a tilt position.

  In a conventional general steering apparatus including the one described in Patent Document 1 described above, a steering column that rotatably supports a steering shaft is provided via a column side bracket fixed to the steering column and a vehicle side bracket fixed to the vehicle. Attached to the vehicle. Among these brackets, the column side bracket is formed with a telescopic long hole extending in the telescopic direction, while the vehicle side bracket is formed with a long tilt hole extending in the tilt direction. In addition, in such a steering device, the support shafts such as bolts inserted through the long holes of both brackets are rotated in the locking direction so that both brackets are in a pressure contact state, and the relative position changes in the telescopic direction and the tilt direction thereof. A lock mechanism is provided that locks the steering position at a position suitable for the driver by restricting the steering.

JP 2001-322552 A

  By the way, in such a lock mechanism, the position of the steering column is basically locked by the frictional force acting on both brackets in the pressure contact state. Even when the lock mechanism is in the lock state in this way, there is some cause. If a force exceeding the frictional force described above is applied to the brackets from the steering wheel via the steering column or the like, the telescopic position or the tilt position may change to a position different from the position suitable for the driving posture. is there. Such technical problems are particularly apparent in a steering apparatus that includes both the telescopic mechanism and the tilt mechanism as described above, but are generally common to steering apparatuses that include only one of the telescopic mechanism and the tilt mechanism. It has become.

  The present invention has been made in view of such a conventional situation, and an object thereof is to suppress a change in a steering position such as a tilt position or a telescopic position in a vehicle steering apparatus.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
A vehicle steering device according to the present invention includes a steering column that rotatably supports a steering shaft, a column side bracket that is fixed to the steering column, and a support that is inserted into each shaft hole of the vehicle side bracket that is fixed to the vehicle. It is premised on having a lock mechanism that locks the position of the steering column with respect to the vehicle by rotating the shaft in the locking direction to bring both brackets into a pressure contact state and restricting the relative position change between them.

  One of the brackets is a long hole whose shaft hole extends in either the telescopic direction or the tilt direction of the steering column and adjusts the position of the steering column in the same direction. A plurality of teeth are provided in a manner along the direction. Further, the support shaft is provided with a cam on which an engagement member having an engagement portion engageable with a plurality of teeth is fitted, and the engagement member is pressed by the cam in conjunction with the rotation of the support shaft. The engaging portion is engaged with a plurality of teeth by elastic deformation. Therefore, in the telescopic direction, the engaging portion of the telescopic engaging member is engaged with the plurality of telescopic teeth, and in the tilt direction, the engaging portion of the tilting engaging member is tilted. Will be engaged with a plurality of teeth. For this reason, even if a force exceeding the frictional force acting on the bracket in the locked state, that is, the pressure contact state, is applied to the bracket from the steering wheel via the steering column or the like, the engagement between the engagement portion and the teeth engaged therewith It is possible to suppress changes in the steering position such as the tilt position and the telescopic position due to the resultant force.

  Here, one of the brackets is provided with a telescopic elongated hole extending in the telescopic direction and a telescopic tooth row as a plurality of teeth, and the other is provided with a tilt elongated hole extending in the tilt direction. A tilting tooth row may be provided as a plurality of teeth. Further, in this configuration, the support shaft is provided with a telescopic cam and a tilt cam. A telescopic engaging member having an engaging portion that engages with a telescopic tooth row is externally fitted to the telescopic cam, while the tilting cam engages with the tilting tooth row. An engaging member for tilting having an engaging portion is externally fitted.

  According to such a configuration, it is possible to suppress both the telescopic position and the tilt position from changing to positions not intended by the driver, and it is possible to more reliably suppress changes in the steering position. .

  Thus, in a steering apparatus including both a telescopic mechanism and a tilt mechanism, it is preferable to employ a configuration in which the telescopic cam and the tilt cam are provided on the support shaft in a manner in which their nose directions are orthogonal to each other. By providing these cams on the support shaft so that the nose directions are orthogonal to each other, if the support shaft is rotated in the lock direction, an operation for engaging the telescopic engagement member with the telescopic tooth row and a tilt operation are performed. The operation of engaging the engaging member with the tooth for tilting can be performed simultaneously. The term “orthogonal” here does not mean that the crossing angle is strictly 90 °. That is, the intersection angle may be within a range in which the telescopic engagement member and the dentition engagement operation and the tilt engagement member and the dentition engagement operation can be performed substantially simultaneously. .

  Moreover, about the some tooth | gear provided in the aspect along the direction where the long hole extends mentioned above, it can comprise by the 1st tooth row and 2nd tooth row which are provided in the state which opposes this. In this case, it is preferable that the cam has a pair of noses extending in opposite directions corresponding to the first tooth row and the second tooth row.

  According to such a configuration, in the locked state, the engaging portion of the engaging member engages with the first tooth row and the second tooth row, and the engagement member at the two portions sandwiching the support shaft. A plurality of teeth come into engagement. Therefore, the effect of suppressing the change of the steering position can be made more remarkable.

  By the way, at the time of a vehicle collision, a so-called secondary collision in which the driver himself collides with a steering wheel or the like may occur due to this. For this reason, it is desirable to install an impact absorbing mechanism for mitigating the impact when the driver collides with the steering wheel during such a secondary collision in the vehicle steering device. In a vehicle steering apparatus equipped with such an impact absorbing mechanism, the telescopic position and the tilt position are not intended by the driver at the time of a secondary collision due to the engaging force between the engaging portion and the tooth with which the engaging portion is engaged. Since it can suppress changing to a position, the original function of an impact-absorbing mechanism can be exhibited suitably. As such an impact absorbing mechanism, in the event of a secondary collision, when a load of a predetermined value or more is applied to the steering column, the steering column is separated from the vehicle, and the steering shaft is moved forward of the vehicle. A mechanism that absorbs the load ahead of the vehicle by contracting the steering column itself when a load greater than a predetermined value is applied.

  In addition, although it may be made to form in a member different from the bracket in which the same long hole is provided, a plurality of teeth provided in the mode in which the above-mentioned long hole extends are formed, this is the bracket in which the long hole is formed If the configuration provided integrally is adopted, it is not necessary to separately provide such another member, so that the number of parts of the steering device can be reduced.

  According to this invention, in a vehicle steering apparatus, it is possible to suppress a change in steering position such as a tilt position or a telescopic position.

Sectional drawing which shows the structure of a plate, a cam, and an engagement member about the steering device of the vehicle concerning other embodiment of this invention.

  First, the overall configuration of the steering apparatus according to the present invention will be described with reference to FIGS. In FIG. 1, members constituting the telescopic mechanism and the tilt mechanism indicated by a two-dot chain line, for example, some members such as a telescopic rack 23 and a tilt rack 36 described later are not illustrated. Yes.

  This steering device includes a steering column 10 that rotatably supports a steering shaft 11, a column side bracket 20 that is fixed to the steering column 10, a vehicle side bracket 30 that is fixed to a vehicle stay 60, and a steering column for the vehicle. 10, that is, a lock mechanism 40 that locks the steering position, and an impact absorbing mechanism 50 that absorbs an impact applied to the steering column 10.

  The column side bracket 20 has a pair of side plates 21 and has a U-shaped cross section when the steering column 10 is viewed in the axial direction. The pair of side plates 21 are formed with mounting holes 22a and mounting holes 22b extending in the telescopic direction. A telescopic rack 23 is attached to one of the attachment holes 22a. The rack 23 is formed with a telescopic elongated hole 23a extending in the telescopic direction.

  On the other hand, the vehicle-side bracket 30 includes a plate 31 attached to a vehicle stay 60 and a clamp 32 fixed to the plate 31. The clamp 32 has a U-shaped cross section when the steering column 10 is viewed in the axial direction. The pair of side plates 32a of the clamp 32 are formed with mounting holes 33a and mounting holes 33b extending in the tilt direction. A tilt rack 36 is mounted in the tilt mounting hole 33a. The rack 36 is formed with a long slot 36a for tilt extending in the tilt direction.

  The lock mechanism 40 includes a bolt 41 inserted through the telescopic long hole 23 a and the tilt long hole 36 a, and a lever 42 that rotates integrally with the bolt 41. The column side bracket 20 and the vehicle side bracket 30 are connected by a bolt 41 inserted through both the long holes 23a and 36a.

  A head 43 of the bolt 41 is provided at one end of the bolt 41, and a lever 42 is incorporated between the head 43 and the vehicle side bracket 30. Since the lever 42 and the head 43 are connected by the connecting member 44, the lever 42 and the head 43 rotate integrally. A washer 45 is incorporated between the lever 42 and the vehicle side bracket 30.

  On the other hand, a nut 48 is screwed to the other end of the bolt 41, and a washer 49 is incorporated between the nut 48 and the vehicle side bracket 30. Therefore, the end of the bolt 41 to which the nut 48 is screwed is fixed.

  The column side bracket 20, the telescopic long hole 23a, the bolt 41, and the like constitute a telescopic mechanism, and the vehicle side bracket 30, the tilt long hole 36a, the bolt 41, and the like constitute a tilt mechanism.

  By rotating the bolt 41 in the direction in which the head 43 is tightened through the lever 42 (the “lock direction” shown in FIG. 1), the distance between the head 43 and the nut 48 is reduced, and each side plate 32a of the vehicle side bracket 30 is moved. It is press-contacted to each side plate 21 of the column side bracket 20. That is, the column side bracket 20 and the vehicle side bracket 30 are in a pressure contact state. Here, the frictional force generated between the brackets 20 and 30 increases according to the angle of the lever 42 in the rotation direction, in other words, according to the fastening degree of the bolt 41. When the frictional force rises to a predetermined value or more, the insertion position of the bolt 41 in the telescopic elongated hole 23a and the tilted elongated hole 36a becomes unadjustable, and the telescopic direction and tilt of the column side bracket 20 with respect to the vehicle side bracket 30 become unadjustable. The relative position change in the direction is regulated. That is, the lock mechanism 40 is locked.

  On the other hand, if the fastening degree of the bolt 41 is lowered by rotating the lever 42 in the direction opposite to the above-described locking direction ("unlocking direction" shown in FIG. 1), the both brackets described above are accordingly provided. The frictional force between 20 and 30 is reduced. When the frictional force is reduced to a predetermined value or less, a relative position change in the telescopic direction and the tilt direction of the column side bracket 20 with respect to the vehicle side bracket 30 is allowed. That is, the lock mechanism 40 is unlocked. As a result, the telescopic position and the tilt position of the steering column 10 can be adjusted by changing the insertion position of the bolt 41 in the telescopic long hole 23a and the tilt long hole 36a.

  The shock absorbing mechanism 50 includes a flat capsule 52 provided between the plate 31 and the stay 60, a collar 53 through which the bolt 51 is inserted, an annular disc spring 54 fitted on the collar 53, An annular housing 55 that accommodates the disc spring 54 is provided. In the plate 31, fastening holes 35 through which the bolts 51 are inserted are respectively formed in the extending portions 34 extending from the clamp 32 to both sides in the vehicle width direction. Then, each extension portion 34 of the plate 31 is fastened to the stay 60 by the bolt 51, so that the vehicle-side bracket 30 is attached to the vehicle via a pair of impact absorbing mechanisms 50. In addition, since the structure of each extension part 34 and each shock absorption mechanism 50 is the same, in FIG. 2, description of one extension part 34 and the shock absorption mechanism 50 is omitted.

  The disc spring 54 is fixed to the stay 60 in a state of being elastically deformed by screwing a nut 56 to the tip side of the bolt 51. Due to the elastic force of the disc spring 54, a frictional force acts between the capsule 52, the plate 31, and the stay 60.

  Therefore, for example, in the event of a secondary collision at the time of a vehicle collision, if a load of a predetermined value or more acts on the vehicle side bracket 30 toward the front of the vehicle via the steering column 10 and the column side bracket 20, the vehicle side bracket 30 absorbs shock. The mechanism 50 is detached from the stay 60 while remaining in the vehicle body. That is, the vehicle side bracket 30 is configured as a so-called breakaway bracket that is detached from the stay 60 when a load of a predetermined value or more is applied. Thus, in the event of a secondary collision at the time of a vehicle collision, the vehicle side bracket 30 is detached from the stay 60 through the impact absorbing mechanism 50 so as to reduce the impact when the driver collides with the steering wheel. Yes.

Next, the structure of the racks 23 and 36 and the peripheral configuration thereof will be described with reference to FIGS.

The telescopic rack 23 constitutes a part of the column side bracket 20 by being mounted in the telescopic mounting hole 22a. That is, the telescopic elongated hole 23 a is formed in the column side bracket 20.

  In the bolt 41, a telescopic cam 46 is provided at a position corresponding to the rack 23. The cam 46 has an engaging portion 71a and a plurality of teeth that engage with a part of the plurality of teeth 25a. A telescopic engaging member 70 having an engaging portion 71b that engages with 26a is externally fitted. The cam 46 is formed with a pair of cam noses 46a and 46b extending in opposite directions.

  The tilt rack 36 is formed with a first tooth row 37 composed of a plurality of teeth 37a and a second tooth row 38 composed of a plurality of teeth 38a in an opposing manner. The rack 36 for tilting constitutes a part of the vehicle side bracket 30 by being mounted in the mounting hole 33a for tilting.

  When the bolt 41 is rotated in the locking direction through the rotation operation of the lever 42, the cam 46 and the engaging member 70 fitted on the cam 46 are interlocked with the bolt 41 as shown in FIG. Then rotate. When the bolt 41 further rotates in the locking direction through the rotation operation of the lever 42, as shown in FIG. 6C, the engaging portion 71a of the engaging member 70 contacts the tooth 25a, and the engaging portion 71b 26a is contacted. In this state, when the bolt 41, the cam 46, and the engaging member 70 are further rotated in the locking direction, the engaging member 70 is pressed by the cam nose 46a, the engaging member 70 is elastically deformed, and the engaging portion 71a is the teeth 25a. And become engaged. At this time, the engaging portion 71b is also engaged with the teeth 26a.
