Description

The present invention relates to a steering apparatus, and more particularly, to a method for assembling a tilt position-adjustable steering apparatus capable of adjusting a tilt position of a steering wheel in accordance with a driver's physique and driving posture.

  As a device for adjusting the vertical position of the steering wheel according to the physique and driving posture of the driver, there is a steering device called a tilt type steering device. Further, as a device for adjusting both the vertical position and the front-back position of the steering wheel, there is a steering device called a tilt / telescopic steering device.

  In such a steering device, as shown in Patent Document 1, the column is always urged upward by the urging force of the spring. This prevents the column from tilting downward due to its own weight when the tilt clamp of the column against the body mounting bracket is released during tilt position adjustment. The tilt position can be adjusted easily.

  In order to assemble the spring to the steering device, it is necessary to stretch the spring between the column and the vehicle body mounting bracket against the urging force of the spring, so that a large force is required for assembling the spring. In particular, in a steering apparatus equipped with a column assist type electric power steering apparatus, the weight of the column is increased, so that the urging force of the spring is inevitably increased, and the force required for assembling the spring is also increased.

  Hereinafter, Example 1 to Example 2 of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall perspective view showing a state in which a steering device of the present invention is attached to a vehicle. As shown in FIG. 1, a hollow cylindrical column 1 is attached to a vehicle body, and a steering shaft 12 is pivotally supported on the column 1 so as to be rotatable. A steering wheel 121 is attached to the steering shaft 12 at the right end (rear side of the vehicle body), and an intermediate shaft 22 is connected to the left end (front side of the vehicle body) of the steering shaft 12 via a universal joint 21.

  The intermediate shaft 22 includes a solid intermediate inner shaft 221 in which a male spline is formed and a hollow cylindrical intermediate outer shaft 222 in which a female spline is formed. The male spline of the intermediate inner shaft 221 is an intermediate outer shaft. The female spline 222 is fitted so as to be extendable (slidable) and transmit rotational torque.

  FIG. 2 is a side view showing a main part of the steering device according to the first embodiment of the present invention. 3 is a view taken in the direction of arrow P in FIG. 4 is a cross-sectional view taken along the line AA in FIG.

  As shown in FIGS. 2 to 4, a steering shaft 12 is rotatably supported in a hollow cylindrical column 1, and a steering wheel is disposed on the rear side of the vehicle body (right side in FIG. 2) of the steering shaft 12. 121 is attached. The vehicle body front side (the left side in FIG. 2) of the column 1 is pivotally supported via a tilt center shaft 51 by lower side vehicle body mounting brackets 5 and 5 attached to the vehicle body 4 with bolts (not shown). .

  Flange portions 52 and 52 for attaching the lower-side vehicle body mounting brackets 5 and 5 to the vehicle body 4 are formed on the upper portions of the lower-side vehicle body mounting brackets 5 and 5. The lower-side vehicle body mounting brackets 5, 5 abut the vehicle body mounting surfaces 52 </ b> A, 52 </ b> A on the vehicle body upper side of the flange portions 52, 52 to the vehicle body 4, and are fastened to the vehicle body 4 with bolts (not shown).

  A substantially intermediate position of the column 1 in the longitudinal direction of the vehicle body is attached to the vehicle body 4 by an upper vehicle body mounting bracket 3. A pair of left and right flange portions 31 </ b> A and 31 </ b> B for mounting the upper side vehicle body mounting bracket 3 to the vehicle body 4 are formed on the upper side of the upper side vehicle body mounting bracket 3.

  The flange portions 31A and 31B are fastened to the vehicle body 4 by bolts (not shown) with the vehicle body mounting surfaces 311A and 311B on the vehicle body upper side of the flange portions 31B and 31B in contact with the vehicle body 4. The flange portions 31A and 31B are formed with a pair of left and right side plates 32A and 32B that are bent in an L shape from the flange portions 31A and 31B and extend downward. The lower ends of the side plates 32A and 32B (downward in FIGS. 2 and 4) are connected and integrated by a U-shaped connecting portion 32C.

  A U-shaped distance bracket 13 is integrally formed below the column 1. The side surfaces 14A and 14B of the distance bracket 13 are sandwiched between the inner side surfaces 321A and 321B of the side plates 32A and 32B of the upper-side vehicle body mounting bracket 3 so as to be tiltable.

  In the distance bracket 13, round holes 15 </ b> A and 15 </ b> B are formed below the axis of the column 1. A tightening rod 34 is inserted from the left side of FIG. 4 (perpendicular to the axis of the column 1) into the long slots for tilt 33A, 33B formed in the side plates 32A, 32B and the round holes 15A, 15B.

  In FIG. 4, a disc-shaped head portion 341 is formed on the left side of the tightening rod 34, and chamfered portions 342 and 342 are formed in parallel on the outer periphery of the head portion 341. The chamfered portion 342 is fitted in the tilt long groove 33A to prevent the tightening rod 34 from rotating with respect to the upper-side vehicle body mounting bracket 3 and to tilt the tightening rod 34 along the tilt long groove 33A.

  The end surface 343 of the head 341 is in contact with the outer surface 322A of the side plate 32A. A male screw 344 is formed on the right side of the tightening rod 34, and a cylindrical nut 35 is screwed into the male screw 344. An end surface 351 of the nut 35 is in contact with the outer side surface 322B of the side plate 32B. An operation lever 36 is fixed to the nut 35 by a washer 37 and a bolt 38. The tightening rod 34, the nut 35, the operation lever 36, and the like constitute a tilt clamp device that clamps the column 1 to the upper body mounting bracket 3 at a predetermined tilt adjustment position.

  When the operation lever 36 is swung, the nut 35 rotates, and the side plates 32A and 32B can be tightened or released from the tightening rod 34. That is, when the operation lever 36 is swung in the tightening direction, the nut 35 rotates, the end surface 351 of the nut 35 moves to the left side in FIG. 4, and the tightening rod 34 moves to the right side in FIG.

As a result, the end surface 351 of the nut 35 tightens the outer surface 322B of the side plate 32B, and the end surface 343 of the head 341 tightens the outer surface 322A of the side plate 32A. by this,
The inner side surfaces 321A and 321B of the side plates 32A and 32B deform the side surfaces 14A and 14B of the distance bracket 13 toward the axis of the column 1. As a result, the side surfaces 14A and 14B of the distance bracket 13 are strongly tightened by the inner side surfaces 321A and 321B of the side plates 32A and 32B, and the tilt clamp is completed.

  When the operation lever 36 is swung in the tightening release direction, the nut 35 rotates, the end surface 351 of the nut 35 moves to the right side in FIG. 4, and the tightening rod 34 moves to the left side in FIG.

  As a result, the force with which the end surface 351 of the nut 35 tightens the outer surface 322B of the side plate 32B is weakened, and the force with which the end surface 343 of the head 341 tightens the outer surface 322A of the side plate 32A is weakened.

  As a result, the inner side surfaces 321A and 321B of the side plates 32A and 32B and the side surfaces 14A and 14B of the distance bracket 13 are elastically returned toward the direction away from the axis of the column 1. As a result, the tightening (tilt clamp) by the inner side surfaces 321A and 321B of the side plates 32A and 32B with respect to the side surfaces 14A and 14B of the distance bracket 13 is released.

  A torsion coil spring 6 that constantly urges the column 1 to the upper side of the tilt (upper side in FIGS. 2 and 4) is stretched between the column 1 and the upper body mounting bracket 3. As shown in FIGS. 2 to 4, the torsion coil spring 6 includes coil portions 61, 61 arranged on both the left and right sides of the axis of the column 1, the inside of the coil portions 61, 61 (on the axis center side of the column 1). ) Extending from the opposite ends of the vehicle body to the vehicle rear side, the abutting portion 63 connecting the vehicle body rear ends of the rear extension portions 62, 62, the outside of the coil portions 61, 61 (away from the axis of the column 1) U-shaped hooks 64 and 64 formed at both ends of the side).

  As shown in FIG. 2, L-shaped hook portions 39, 39 are formed on the side plates 32 </ b> A, 32 </ b> B of the upper-side vehicle body mounting bracket 3 so as to protrude away from the axis of the column 1. U-shaped notch grooves 391 and 391 are formed at both ends of the L-shape in the hook portions 39 and 39, and the width of the notch grooves 391 and 391 is slightly wider than the wire diameter of the coil spring 6. ing.

  When the hooks 64, 64 of the torsion coil spring 6 are hooked on the notch grooves 391, 391, the abutting portion 63 of the torsion coil spring 6 abuts on the lower surface of the outer periphery of the column 1, and the notch grooves 391 391 and the column 1 The torsion coil spring 6 is stretched between the outer periphery of the coil. Then, the torsion coil spring 6 is twisted between the hooks 64, 64 and the contact portion 63, and a biasing force is generated in the contact portion 63. As shown by an arrow F1 in FIG. 1 is applied with an urging force to tilt upward.

  As a result, when the tilt clamp of the column 1 with respect to the upper-side vehicle body mounting bracket 3 is released at the time of tilt position adjustment, the column 1 is prevented from tilting downward due to its own weight, and the column 1's own weight is supported by hand. Even without this, the tilt position of the steering wheel 121 can be easily adjusted.

  The distance between the hooks 64 and 64 of the torsion coil spring 6 in the vehicle width direction (vertical direction in FIG. 3) is formed slightly narrower than the distance between the notch grooves 391 and 391 in the vehicle width direction. Accordingly, when the hooks 64 and 64 are hooked in the notch grooves 391 and 391, a preload in the vehicle width direction is generated between the torsion coil spring 6 and the notch grooves 391 and 391, and the torsion coil spring 6 is notched in the notch grooves 391 and 391. 391 so that it does not deviate from 391.

  As shown in FIG. 4, the upper-side vehicle body mounting bracket 3 has an opening 30 formed in the upper part of the inner side surfaces 321A and 321B of the side plates 32A and 32B, and the column 1 and the distance bracket 13 are on the vehicle body upper side (tilt upper side). Side). Accordingly, the column 1 and the distance bracket 13 can be assembled to the upper-side vehicle body mounting bracket 3 from the upper side of the vehicle body with the hooks 64 and 64 of the torsion coil spring 6 hooked in the notch grooves 391 and 391. ing.

  Next, a procedure for assembling the torsion coil spring 6 and the like to the above-described steering apparatus of the present invention will be described. FIG. 5 is an explanatory view showing a first step of the assembly process of the steering device according to the first embodiment of the present invention, wherein (1) is a side view showing a state in which a torsion coil spring is attached to the upper body mounting bracket; 2) is a view in the direction of arrow Q in (1).

  FIG. 6 is an explanatory diagram showing a second step of the assembly process of the steering device according to the first embodiment of the present invention. 7 is a cross-sectional view taken along line BB in FIG. FIG. 8 is an explanatory diagram showing a third step of the assembly step of the steering device according to the first embodiment of the present invention. FIG. 9 is an explanatory view showing a fourth step of the assembly step of the steering device according to the first embodiment of the present invention. FIG. 10 is a view taken in the direction of the arrow R in FIG. 11 is a cross-sectional view taken along the line CC of FIG.

  First, as shown in the first step of FIG. 5, the hooks 64, 64 of the torsion coil spring 6 are hooked in the notch grooves 391, 391 of the hook portions 39, 39 of the upper-side vehicle body mounting bracket 3.

  Next, as shown in the second step of FIGS. 6 and 7, the column 1 to which the lower-side vehicle body mounting bracket 5 is attached is attached to the assembly jig 7. The posture in which the column 1 is attached to the assembly jig 7 is upside down with respect to the posture in which the column 1 is attached to the vehicle body 4 in FIGS. That is, the flange parts 52 and 52 of the lower-side vehicle body mounting brackets 5 and 5 are on the lower side, and the vehicle body mounting surfaces 52A and 52A of the flange parts 52 and 52 are in contact with the upper surface 71 on the left side of the assembly jig 7, The flanges 52 and 52 are attached with bolts that do not.

  Subsequently, the upper-side vehicle body mounting bracket 3 to which the hooks 64, 64 of the torsion coil spring 6 are hooked is placed on the lower side of the flange portions 31A, 31B of the upper-side vehicle body mounting bracket 3 (the upper-side vehicle body mounting bracket 3 is attached to the vehicle body 4). With respect to the mounting posture, the upper and lower sides of the assembly jig 7 are in contact with the upper surface 72 on the right side of the assembly jig 7, and the vehicle body mounting surfaces 311A and 311B of the flange portions 31A and 31B are brought into contact. Attach 31B.

  As described above, the upper-side vehicle body mounting bracket 3 has a structure in which the opening 30 is formed in the upper part (tilt upper side) of the side plates 32A and 32B so that the column 1 and the distance bracket 13 can pass therethrough. Accordingly, the upper side body mounting bracket 3 is placed on the column 1 and the distance bracket 13 from the upper side in FIG. 6 without interfering with the column 1 and the distance bracket 13, and then the upper surface 72 on the right side of the assembly jig 7. Further, it is possible to attach the upper-side vehicle body mounting bracket 3 with a bolt (not shown).

  As shown in FIG. 6, the column 1 pivots clockwise around the tilt center axis 51 by the weight of the column 1. Therefore, the outer periphery of the column 1 is below the contact portion 63 of the torsion coil spring 6, and the contact portion 63 does not contact the outer periphery of the column 1. Accordingly, since no urging force is applied to the column 1 from the contact portion 63 of the torsion coil spring 6, the urging force of the torsion coil spring 6 is applied to the upper side when the upper body mounting bracket 3 is attached to the upper surface 72 of the assembly jig 7. It does not act on the body mounting bracket 3.

  Subsequently, as shown in FIG. 6, the column 1 is pivoted counterclockwise (in the direction of arrow S in FIG. 6) with the right end of the steering shaft 12 of the column 1 as a fulcrum. Then, the side surfaces 14A and 14B of the distance bracket 13 integral with the column 1 slide along the inner side surfaces 321A and 321B of the side plates 32A and 32B of the upper-side vehicle body mounting bracket 3. When the column 1 is pivoted counterclockwise, the outer periphery of the column 1 comes into contact with the contact portion 63 of the torsion coil spring 6.

  Then, the torsion coil spring 6 is twisted between the hooks 64, 64 and the contact portion 63, and an urging force is generated in the contact portion 63. As shown by an arrow F2 in FIG. 1 is given a downward biasing force. The column 1 is further pivoted counterclockwise against this biasing force.

  The distance between the tilt center axis 51 and the right end of the steering shaft 12 of the column 1 is set to be many times larger than the distance between the hooks 64, 64 and the contact portion 63. Therefore, a large force is not required to pivot the column 1 counterclockwise against the biasing force of the torsion coil spring 6.

  As shown in the third step of FIG. 8, the column 1 is pivoted counterclockwise to a position where the central axis of the column 1 is substantially horizontal (substantially intermediate position of the tilt adjustment position of the column 1). In this state, the entire round holes 15 </ b> A and 15 </ b> B of the distance bracket 13 are positioned in the long slots for tilt 33 </ b> A and 33 </ b> B of the column 1.

  Next, as shown in the fourth step of FIGS. 9, 10, and 11, the tightening rod 34 is inserted from the right side of FIG. 11 into the tilting long grooves 33 </ b> A and 33 </ b> B and the round holes 15 </ b> A and 15 </ b> B. The nut 35 is firmly screwed into the left male screw 344.

  As a result, the nut 35 rotates, the end surface 351 of the nut 35 moves to the right side of FIG. 11 and the clamping rod 34 moves to the left side of FIG. 11, and the side surfaces 14A and 14B of the distance bracket 13 Tightened by the inner side surfaces 321A and 321B of 32B, the tilt clamp of the column 1 is completed. Thereafter, the operation lever 36 is fixed to the nut 35 with a washer 37 and a bolt 38.

  This completes the work of assembling the torsion coil spring 6 and the like to the steering device of the present invention. Thereafter, the steering device is removed from the assembly jig 7 and attached to the vehicle body 4 with the steering device turned upside down.

  Next, a second embodiment of the present invention will be described. FIG. 12 is an explanatory view showing a fourth step of the assembly step of the steering device according to the second embodiment of the present invention. In the following description, only the parts different from the first embodiment will be described, and redundant description will be omitted. Further, the same parts as those in the first embodiment will be described with the same numbers.

  The second embodiment is a modification of the first embodiment and is an example applied to a steering device having an electric power steering device. That is, as shown in FIG. 12, the electric power steering device 16 is attached to the front side of the vehicle body of the column 1 (left side of FIG. 12). The front end of the vehicle body of the electric power steering device 16 is pivotally supported by the lower body mounting brackets 5 and 5 via a tilt center shaft 51.

  The lower-side vehicle body mounting brackets 5 and 5 are formed with flange portions 52 and 52 for mounting the lower-side vehicle body mounting brackets 5 and 5 to the assembly jig 7 (vehicle body 4). The structures of the upper-side vehicle body mounting bracket 3 and the torsion coil spring 6 used in the steering device of the second embodiment are the same as those of the first embodiment.

  The electric power steering device 16 detects the steering torque of the steering shaft 12 and applies an auxiliary steering force proportional to the steering torque to the steering shaft 12.

  In such a column assist type steering apparatus to which the electric power steering apparatus 16 is attached, the weight of the column 1 is increased, so that the rotational moment of the column 1 with the tilt center axis 51 as a fulcrum is increased. Therefore, in order to prevent the column 1 from tilting downward due to the weight of the column 1 when the tilt clamp of the column 1 is released, it is necessary to increase the biasing force of the torsion coil spring 6.

  In such a steering device to which the electric power steering device 16 is attached, the upper-side vehicle body mounting bracket 3 having the same structure as that of the first embodiment is used, and the torsion coil is used using the assembly jig 7 having the same structure as that of the first embodiment. If the spring 6 is assembled, it can be assembled without requiring a large force.

  In the above-described embodiment, an example in which the present invention is applied to a steering apparatus capable of only tilt position adjustment has been described. However, the present invention may be applied to a steering apparatus capable of both tilt position adjustment and telescopic position adjustment.
