Description

  The present invention relates to a steering column device having a tilt / telescopic function for an automobile.

  Some steering column devices include a tilt mechanism that adjusts the vertical position of the steering wheel according to the physique and posture of the driver, and a telescopic mechanism that adjusts the front and rear position of the steering wheel. In the steering column device equipped with a telescopic mechanism, when the vehicle collides and the driver has a secondary collision with the steering wheel, the steering column does not move upward or move forward. There is one in which a plurality of friction plates are alternately stacked and firmly clamped.

  As a conventional steering column device using a plurality of friction plates, for example, the one described in Patent Document 1 is known. In this steering column device, a friction plate for tilting and a telescopic friction plate are alternately inserted into a tightening lock bolt to increase the frictional force at the time of locking. In a steering column device in which this type of friction plate is overlapped, it is difficult to secure a sufficient gap between the friction plates when the lock is released. Therefore, the operating force is heavy due to the frictional force between adjacent friction plates during tilt and telescopic operation. There is a problem.

  Therefore, in this Patent Document 1, a compression spring that penetrates the friction plate is provided between the holding jaw that holds the friction plate and the contact plate, and the compression spring is used to release the lock between the holding jaw and the contact plate when the lock is released. Is expanded to secure a gap between the friction plates.

  Hereinafter, a steering column apparatus with a tilt / telescopic function according to an embodiment of the present invention will be described with reference to the drawings.

  1-4, 4 is a lower jacket, 5 is an upper jacket, and 2 is a steering shaft. A jacket 1 is configured by a lower end portion of the upper jacket 5 being movably inserted into an upper end portion of the lower jacket 4 so as to cover the upper end portion of the lower jacket 4. A telescopic steering shaft 2 is rotatably supported inside the jacket 1. The steering shaft 2 is configured to be extendable and contractable by serration-coupling the lower shaft 2a and the hollow upper shaft 2b.

  A vehicle body mounting bracket 10 for mounting the jacket 1 is coupled to the vehicle body. The vehicle body mounting bracket 10 is provided with a pair of side brackets (also referred to as side plates) 11A and 11B. An upper jacket 5 is disposed between the pair of side brackets 11A and 11B, and a pair of distance brackets 6 and 6 that are in contact with the inner side surfaces of the pair of side brackets 11A and 11B are integrally coupled to the upper jacket 5. ing.

  A plurality of tilt friction plates 28 and telescopic friction plates 29 are alternately stacked on the outer surface of one side bracket 11A. The tilt friction plate 28 is an engagement protrusion formed on the tilt friction plate 28 disposed on the outermost side, an engagement hole 13 provided on the side bracket 11A side, and an engagement formed on another tilt friction plate 28. The telescopic friction plate 29 is connected to the upper jacket 5 by a pin 6 a provided on the distance bracket 6 by engagement with the hole 28 b.

  Each of the pair of side brackets 11A, 11B and the tilt friction plate 28 is formed with tilt long holes 12, 28a extending in the vertical direction. The distance bracket 6 and the telescopic friction plate 29 are formed with telescopic elongated holes 7 and 29a extending in the front-rear direction. The elongated slots 12 and 28a formed in the side brackets 11A and 11B and the tilt friction plate 28 and the telescopic elongated holes 7 and 29a formed in the distance bracket 6 and the telescopic friction plate 29 are substantially cross-shaped. It is arranged to intersect.

  Further, a collar 25 as a pressing member and a fixed cam 31 are arranged on the outer sides of the pair of side brackets 11A and 11B. The collar 25 is disposed outside the outermost friction plate 28 on the side where the friction plates 28 and 29 are provided. The fixed cam 31 is disposed outside the side bracket 11B on the side where no friction plate is provided.

  The collar 25 includes the side bracket 11A and the tilt long holes 12 and 28a of the tilt friction plate 28, which are arranged so as to intersect substantially in a cross shape, and the telescopic long holes 7 and 29a of the distance bracket 6 and the telescopic friction plate 29. It has a substantially quadrangular rectangular tube portion 25a that is inserted through both sides, and a flange portion 25b that is formed at the end of the rectangular tube portion 25a and contacts the outer surface of the outermost friction plate 28.

  The fixed cam 31 is inserted into both of the tilting long hole 12 of the side bracket 11B and the telescopic long hole 7 of the distance bracket 6 which are arranged so as to intersect with each other in a substantially cross shape. And a flange portion 31b that is formed at the end of the rectangular tube portion 31a and faces the outer surface of the side bracket 11B.

  Further, the lock bolt 21 is inserted so as to penetrate from the fixed cam 31 which is one pressing member to the collar 25 which is the other pressing member. Thereby, since the lock bolt 21 is supported by the distance bracket 6 via the square tube portions 25a and 31a, the support rigidity of the lock bolt 21 is improved. The lock bolt 21 is inserted into the fixed cam 31 and the collar 25, so that the tilt long holes 12, 28a formed in the pair of side brackets 11A and 11B and the tilt friction plate 28, the distance bracket 6 and the telescopic friction plate are formed. The telescopic elongated holes 7 and 29a formed in 29 are penetrated.

  The distal end 21 a of the lock bolt 21 penetrates the collar 25 and is screwed into the nut 27, and the tensile force generated in the lock bolt 21 is applied to the collar 25 between the nut 27 and the flange portion 25 b of the collar 25. A washer 22 and a thrust bearing 23 for effectively transmitting to the flange portion 25b are sandwiched. Further, a support plate 60 for receiving a biasing force of a spring 70 for biasing the jacket 1 upward is sandwiched between the flange portion 25 b of the collar 25 and the outermost friction plate 29.

  By applying a tensile force to the lock bolt 21 on the head 21 b side of the lock bolt 21, the distance brackets 11 </ b> A and 11 </ b> B, the side bracket 6, and the friction plates 28 and 29 are connected to each other via the fixed cam 31 and the collar 25. Tightening means 20 is provided that applies surface pressure to the contact surface and locks the jacket 1 with the frictional force, while releasing the tensile force to release the frictional force and unlock the jacket 1.

  The tightening means 20 generates a tensile force on the lock bolt 21 by rotating the lock bolt 21 in one direction, and a cam mechanism 30 that releases the tensile force by rotating the lock bolt 21 in the other direction. And an operation lever 35 for rotating the lock bolt 21. The cam mechanism 30 is composed of the fixed cam 31 and the movable cam 32, and the lock bolt 21 and the movable cam 32 are rotated in one direction by the operation of the operation lever 35, and the peak portion of the cam surface of the fixed cam 31. When the crest 31b and the crest portion 32b of the cam surface of the movable cam 32 are in a butt-on state, the fixed cam 31 and the movable cam 32 are separated from each other to apply a tensile force to the lock bolt 21 to create a locked state. When the lock bolt 21 and the movable cam 32 are rotated in the other direction by the operation of the operation lever 35 and the peak portion of one cam surface and the other valley portion of the fixed cam 31 and the movable cam 32 face each other, the fixed cam 31 and the movable cam 32 are close to each other so as to release the tensile force applied to the lock bolt 21 to create a release state.

  A support plate 60 for receiving a biasing force of a spring 70 for biasing the jacket 1 upward is also provided between the flange portion 31b of the fixed cam 31 constituting the cam mechanism 30 and the outer surface of the side bracket 11B. It is sandwiched.

  As shown in FIG. 5, the support plate 60 has a diamond-shaped through hole 62 through which the rectangular tube portion 25 a of the collar 25 passes, and between the flange portion 25 b of the collar 25 and the outer surface of the side bracket 11 </ b> A. It has a flat part 61 to be sandwiched and a spring receiving part 63 formed on the lower side of the flat part 61, and the spring receiving part 63 projects from the flat part 61 to the outside in the plate thickness direction in the shape of a bowl having a cross-sectional shape. So as to be offset. A support blade 60 having a similar shape is also provided between the flange portion 31b of the fixed cam 31 and the outer surface of the side bracket 11B.

  Further, the spring 70 shown in FIG. 6 is formed by bending a wire having a circular cross section into a substantially U shape in plan view, and is attached so as to straddle the vehicle body mounting bracket 10 as shown in FIGS. 1 and 2. And a pair of free tip portions 73, 73 extending from both ends of the mount portion 71, and between the mount portion 71 and each free tip portion 73. And a spirally wound portion 72 for applying an urging force to the.

  Then, the attachment portion 71 is attached to the vehicle body attachment bracket 10, and the two free tip portions 73 of the spring 70 are engaged with the spring receiving portions 63 of the pair of support plates 60, 60 from below as shown in FIG. By stopping, the urging force of the spring 70 is applied to the support plate 60 upward and outward (in the direction of arrow X in FIG. 4). Further, this urging force acts on the collar 25 and the distance bracket 6 to urge the upper jacket 5 upward.

  Further, as shown in FIG. 4, a cam member 50 is serrated and fitted to an intermediate portion in the axial direction of the lock bolt 21. The cam member 50 can rotate integrally with the lock bolt 21, and the outer peripheral surface of the lower jacket 4 is made the inner peripheral surface of the upper jacket 5 when the lock bolt 21 is rotated and the fastening means 20 is locked. The lower jacket 4 is prevented from rattling with respect to the upper jacket 5. On the other hand, when the lock bolt 21 is turned to release the tightening, the lower jacket 4 is separated from the lower jacket 4. .

  Next, the operation of the steering column device with the tilt / telescopic function configured as described above will be described.

  When performing tilt adjustment or telescopic adjustment, the operation lever 35 is rotated and the movable cam 32 is rotated. Then, the crests and troughs of the cam surfaces of the movable cam 32 and the fixed cam 31 face each other, and the fixed cam 31 and the movable cam 32 approach each other. For this reason, the tensile force of the lock bolt 21 is released and the lock is released. Accordingly, it is possible to adjust the tilt of the jacket 1 by moving the lock bolt 21 along the elongated slots 28a and 12 for tilting.

  Further, by moving the distance bracket 6 relative to the lock bolt 21 along the front-rear direction, the upper jacket 5 can be moved along the front-rear direction (axial direction) for telescopic adjustment.

  At the same time, since the spring 70 is attached to the lower end of the support plate 60 in an offset state with respect to the support plate 60, the distance bracket 6 is biased upward via the lock bolt 21 by the biasing force of the spring 70. As the support plate 60 moves outward, the collar 25 moves outward, so that a gap can be positively opened between the contact surfaces of the tilt friction plate 28 and the telescopic friction plate 29. Accordingly, it is possible to reduce the operation force of the tilt operation and the telescopic operation.

  When the tilt adjustment and telescopic adjustment are completed, the operation lever 35 is rotated in the opposite direction, and the lock bolt 21 is tightened by the action of the cam mechanism 30. In this way, the upper bracket 5 is locked by the side brackets 11 </ b> A and 11 </ b> B strongly sandwiching the distance bracket 6. At this time, since the tilt friction plate 28 and the telescopic friction plate 29 are arranged in an overlapping manner, the frictional resistance increases due to an increase in the number of friction plates in frictional contact with each other, and the driver is secondary to the steering wheel (not shown). Even in the event of a collision, there is no risk of tilt slip or telescopic slip.

  In addition, since the spring 70 for urging the collar 25 outward in the above configuration also urges the jacket 1 upward, unnecessary springs can be reduced. In addition, since the support plate 60 is added and the function of urging the support plate 60 outward is only required to be added to the spring 70 urging the jacket 1 upward, an increase in the number of parts can be reduced, Assembling is also improved.

  In the above embodiment, the steering column device including both the tilt mechanism and the telescopic mechanism has been described. However, the present invention can also be applied to a steering column device including only the tilt mechanism.

  In this case, referring to FIGS. 1 to 4, the telescopic steering shaft 2 is rotatably supported inside the jacket 1, and a pair of side brackets 11 </ b> A and 11 </ b> B are coupled to the vehicle body. The jacket 1 is disposed between the side brackets 11A and 11B, and a pair of distance brackets 6 and 6 that are in contact with the inner side surfaces of the pair of side brackets 11A and 11B are integrally provided on the jacket 1, and the side brackets 11A and 11B Tilt friction plates 28 and spacers (corresponding to 29) made of washers or the like are alternately superposed on at least one outer surface, and the tilt friction plates 28 are coupled to the side bracket 11A, while the spacer 29 is A pair of side brackets 11A and 11B and a tilt wear are held by the lock bolt 21. Tilt long holes 12 and 28a formed in each of the plates 28 and through holes 7 and 29a formed in the distance bracket 6 and the spacer 29 (in this case, not through the telescopic long holes but through holes). The corners of the fixed cam 31 and the collar 25 are arranged so as to overlap and are inserted into both the tilt long hole 28a of the tilt friction plate 28 and the through hole 29a of the spacer 29 and the tilt long hole 12 of the side brackets 11A and 11B. Tube portions (in this case, a square tube portion may be used as a rotation stop for the tilting long hole 12) 25a, 31a and the outermost friction plate 28 formed at the ends of the tube portions 25a, 31a The pressing member (the collar 25 and the fixed cam 31) having the flange portions 25b and 31b facing the outer side surface or the outer side surface of the side bracket 11B is a pair of side brackets. A pair of lock bolts 21 are provided on the outer sides of the locks 11 </ b> A and 11 </ b> B, and a lock bolt 21 is inserted so as to penetrate from one pressing member (fixed cam 31) to the other pressing member (collar 25). By applying a force, surface pressure is applied to the contact surfaces of the distance bracket 6, the side brackets 11 </ b> A and 11 </ b> B, the tilt friction plate 28 and the spacer 29 via a pair of pressing members (the fixed cam 31 and the collar 25). The steering column device is provided with a tightening means 20 that locks the jacket 1 with the frictional force and removes the frictional force to release the lock of the jacket 1 by releasing the tensile force.

  In such a steering column device, the support plate 60 for receiving the biasing force of the spring 70 biasing the jacket 1 upward is provided between the flange portion 25b of the pressing member 25 and the outermost friction plate 28. At the same time, the spring 70 is locked to the support plate 60, thereby applying a biasing force toward the outer side in the axial direction of the lock bolt 21 to the flange portions 25 b and 31 b of the pair of pressing members 25 and 31.

  Moreover, although the case where the friction plates 28 and 29 were arrange | positioned on the outer side of one side bracket 11A was demonstrated in the said embodiment, you may arrange | position on the outer side of both side brackets 11A and 11B. Further, the number of friction plates 28 and 29 may be any number as long as it is at least one. In the above embodiment, the support plate 60 is disposed on both outer sides of the side brackets 11A and 11B. However, the support plate 60 may be disposed only on the side where the tilt and telescopic friction plates are provided.
