Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a steering wheel position adjusting device capable of simplifying a tilt operation mechanism of a steering wheel.
[0002]
[Prior art]
Conventionally, various steering devices having a tilt function have been developed. First, Japanese Examined Patent Publication No. 48-33567 discloses a Y-Y direction fixing elongated hole along a steering handle bracket fixed to the vehicle body side, and a stay integral with the housing in the X-Y direction substantially orthogonal to the Y-Y direction. An X-direction fixing long hole is provided, and is connected to a shaft middle and a shaft lower via a shaft upper and a universal joint to which a steering handle is attached, and a spline meshing connection is provided on the shaft middle and the shaft lower. It is shown that the Y-Y direction movement is possible and the steering handle can be adjusted simultaneously in the X-X direction and the Y-Y direction.
[0003]
In this adjustment, the joint portion of the universal joint between the shaft upper and the shaft middle serves as a support portion (fulcrum), but the support portion moves only in the YY direction while the XX direction is held stationary (one direction). It is present on the shaft center of the shaft middle. That is, in the shaft swing direction, the support portion is displaced only in the axial direction in a stationary state.
[0004]
Next, in Japanese Utility Model Publication No. 62-130947, in a device that adjusts the steering handle position up and down or back and forth, a connecting portion that is movably connected only in the axial direction to an intermediate shaft that connects the column shaft and the steering gear. The intermediate shaft expands and contracts and the shaft swings in accordance with the vertical and vertical adjustment positions of the column shaft, and the support portion of the coupling joint between the column shaft and the intermediate shaft moves in the axial direction and the axial swing direction. What is displaced is shown.
[0005]
Next, in Japanese Utility Model Publication No. 2-24366, the tilt adjusting device as described above and the intermediate shaft expand and contract in the axial direction to follow and rotate, and are displaced in the axial direction of the steering shaft below the column. The one provided with a supporting part is shown.
[0006]
Next, in Japanese Utility Model Laid-Open No. 48-14729, a vertical slot is provided on both sides of the bracket on the vehicle body with a position fixing screw and a longitudinal slot on the steering handle side of the bracket on the column side, and vice versa. A structure is shown in which a support hole is provided below the side and a support portion in the front-rear direction is displaced in the front-rear direction and is displaced only in the vertical direction (shaft axis direction) in the bracket. Further, Japanese Utility Model Publication No. 60-37891 and Japanese Utility Model Publication No. 59-41895 each show a mechanism capable of tilting operation based on a simple structure.
[0007]
[Problems to be solved by the invention]
Each of the above-described prior arts is a device that adjusts the steering handle to an appropriate position by adjusting the vertical and vertical positions together. When the support part below the column follows the movement of the column shaft in the vertical / front / rear position adjustment, the support part position is not constrained, so that the adjustment range can be adjusted appropriately.
[0008]
However, the position of the support part with respect to the combined position in the long hole direction on the top and bottom and front and back of the bracket only changes depending on the follow-up position, and the position in the top and bottom long hole direction with respect to the front and back long hole direction position formed on the bracket That is, the adjustment in the vertical swing direction is performed by a single unit along the long hole.
[0009]
Therefore, even if the steering handle is adjusted to the appropriate position by adjusting the steering handle up or down in the front-rear position, the physique and posture of the driver are adjusted for adjustment according to the range of the vertical swing angle around the support portion. It was difficult to arbitrarily adjust to the optimum position as expected. If it is possible to adjust the slight tilt of the steering wheel slightly upward or downward at an appropriate position by the adjustment, the driver will not adjust to the position of the adjustment range but to the driver's preferred position. It seems that the steering operation of the driver can be improved. However, in the conventional structure, the steering handle cannot be finely adjusted, and the adjustment to the optimal position cannot be sufficiently performed.
[0010]
Further, in the conventional structure which has a support portion below the column and adjusts the steering handle at an arbitrary position in a single direction along the longitudinal holes in the front-rear direction and the up-down direction, the steering handle is swung up and down. There is no concept of further adjusting the upper or lower diagonal direction with respect to any position within the angular range, and the steering handle surface is slightly changed based on this structure (which adjusts the vertical position around the support). It was not considered at all to make it changeable, and it was difficult to achieve with a simple structure.
[0011]
If it is considered to change the inclination of the operation surface of the steering handle based on the conventional structure, it is conceivable to add a spherical bearing that changes the steering handle surface to the mounting portion between the steering shaft and the steering handle. However, if such a configuration is added, the apparatus becomes very complicated accordingly, the number of parts increases, the cost increases, and it is difficult to reduce the size and weight of the apparatus.
[0012]
From the above, there is no structure in the prior art that adjusts the rotational operation surface of the steering handle in the device for adjusting the tilt position. Therefore, development of a new steering wheel position adjusting device that can easily adjust the tilt of the steering wheel operation surface by the tilt position adjusting device is expected.
[0013]
[Means for Solving the Problems]
Accordingly, as a result of earnest and research to solve the above problems, the inventor has mounted the present invention on a fixed bracket fixed to a vehicle body, a movable bracket sandwiched between the fixed bracket, and the movable bracket. A steering shaft, a horizontally long hole formed in one of the fixed bracket and the movable bracket, a vertically long hole formed on the other side of the fixed bracket or the movable bracket, and the horizontally long hole and the vertically long hole. The movable bracket is mounted in the fixed bracket, and a range where the horizontally long hole intersects the vertically long hole is defined as a long hole intersecting portion, and the long hole intersecting portion is defined as an axial direction of the steering shaft. The arm part is fixed to the fastening shaft that penetrates the crossing part of the long holes, and the link part is connected to both the arm parts. The steering handle position adjustment device that simultaneously rotates the fastening shafts penetrating through the hole intersections so that the fixed bracket and the movable bracket can be appropriately fixed can be used to adjust the tilt of the steering handle. In addition, the tilt of the rotational operation surface of the steering handle can be adjusted with a very simple structure and operation, which solves the above problems.
[0014]

Can do. The tilt position can be firmly fixed by tightening the tightening shaft 5 with the steering handle position set at the desired tilt position.
[0021]
A steering shaft 10 is supported and fixed to the movable bracket 2 (see FIG. 3). The steering shaft 10 includes a shaft member 10a on which a steering handle 15 is mounted, and a column member 10b that rotatably supports the shaft member 10a. The steering shaft 10 is connected to the steering gear 11 via an intermediate shaft 12. Yes. The steering gear 11 steers the wheels via a rack and pinion.
[0022]
The intermediate shaft 12 is a rigid shaft that cannot be expanded and contracted in the axial direction. The intermediate shaft 12 has one end in the axial direction as a swing center portion 12c. The swing center portion 12c is connected to the steering gear 11 via a universal joint 13 (universal joint), and the swing center portion 12c. Is configured to be swingable with reference to the swing center (see FIGS. 5 and 13).

As a result, the steering shaft 10 can adjust the tilt of the steering handle 15 with the long shaft intersections A ₁ and A ₁ as the movable fulcrums while following the movement locus of the connecting portion 12d by the swinging motion of the intermediate shaft 12. (See FIGS. 5 and 13).
[0025]
In addition, in the movable range of the long hole intersecting portion A _{1 by} the horizontally long hole 3 and the vertically long hole 4, the telescopic adjustment of the steering handle 15 can be performed in addition to the tilt adjustment, and the longitudinal direction of the vertically long hole 4 is made relatively long. As a result, the tilt of the operation rotation surface of the steering handle 15 can be adjusted (see FIGS. 10A, 11A, and 11B). There is an embodiment in which the long hole intersection A ₁ is provided at two locations along the axial direction of the steering shaft 10.
[0026]
In the above-described embodiment, the long hole intersections A ₁ and A ₁ in the tilt operation are provided at two locations along the axial direction, and the long hole intersections A ₁ and A ₁ have a distance t shifted from each other. . When the rotational operation surface is slightly changed and adjusted depending on the direction (up or down) in which the steering handle 15 is adjusted, either _one of the long hole intersecting portions A ₁ and A ₁ serves as a movable support portion. The rotational operation surface can be adjusted in an oblique direction other than the tilt direction (see FIG. 6).
[0027]
In addition to the tilt adjustment, a more optimal position for the driver can be obtained by slightly adjusting the tilt of the operation surface of the steering wheel 15. Then, the lever 6 is mounted on the tightening shaft 5 that passes through the long hole intersection A ₁ on the side close to the steering handle 15.
[0028]
Further, the two fastening shafts 5 penetrating the two long hole intersections A ₁ and A ₁ are simultaneously rotated to simultaneously tighten and release the two long hole intersections A ₁ and A ₁ . The following embodiments exist as structures that can be performed. Specifically, the arm portions 7 and 7 that rotate together with the fastening shafts 5 and 5 of the two long hole intersections A ₁ and A ₁ are fixed, and the link portion 8 is connected to both the arm portions 7 and 7. (See FIGS. 1 and 2).
[0029]
When the tightening shaft 5 on which the lever 6 is mounted is the main drive side, the other tightening shaft 5 is the driven side, the lever 6 is operated on the main drive side, and the tightening shaft 5 is rotated, the arm portion 7 Further, the arm portion 7 and the fastening shaft 5 on the driven side are rotated in conjunction with each other via the link portion 8 (see FIG. 2B). Further, as a second embodiment of the structure for rotating the two fastening shafts 5 at the same time, as shown in FIGS. 14A and 14B, an operation arm member 23 that rotates together with the lever 6, An operation arm member 24 that is rotated by an operation arm member 23 is provided. The operation arm member 23 is interlocked with the lever 6 side by a fastening shaft 5 on the vehicle body rear side, and the operation arm member 24 is on the vehicle body front side. This is interlocked with the tightening shaft 5.

Specifically, the engaged portion 24a is formed in a bifurcated shape, and the engaging portion 23a at the tip of the operation arm member 23 is inserted and engaged. The engagement structure between the engagement portion 23a and the engaged portion 24a is not limited to the above specific example, and various engagement structures such as pin bonding may be used. Due to the engagement of the engaging portion 23a and the engaged portion 24a, the operated arm member 24 is rotated by the rotating operation of the operating arm member 23. The operation arm member 23 and the operated arm member 24 are opposite to each other in the rotation direction, and accordingly, the fastening shafts 5 and 5 at the two long hole intersections A ₁ and A ₁ are threaded together. Different directions are used.
[0031]
In this way, the tightening shafts 5 and 5 are both tightened and released simultaneously. In addition, it is good also as an electric interlocking type which adjusts a steering-wheel handle by providing an electrically-driven part and performing fastening and cancellation | release of the fixed bracket 1 and the movable bracket 2 by switch operation etc.
[0032]
There are various types of the long hole intersection A ₁ . First, as the first type, with the steering shaft 10 in the initial setting position (neutral position), the long hole crossing portion A ₁ is spaced a predetermined distance in the direction of the steering shaft 10 and according to the axial direction of the steering shaft 10. They are provided on the same horizontal line (see FIG. 8).
[0033]
Next, as the second type of long hole intersection A _1, when the steering shaft 10 to the initial position, provided the distance t of the stepped elongated hole intersection of two positions A _1, the A ₁ in the vertical direction Thus, they are appropriately positioned on different lines along the axial direction of the steering shaft 10. Specifically, one in which a position near the long hole intersection A ₁ of the front side to the steering shaft 10, and a distant position of the steering wheel 15 nearest side long hole intersections A ₁ to the steering shaft 10 [6 (See (A)). In contrast to the above, the long hole intersection A ₁ on the front side is located far from the steering shaft 10, and the long hole intersection A ₁ near the steering handle 15 is located near the steering shaft 10 [FIG. 6 (B)].
[0034]
It should be noted that the vertical hole 4 on the side close to the steering handle 15 of the long hole intersections A ₁ , A ₁ or the opposite side thereof is made longer in the upward or downward direction centering on the intersection with the horizontal long hole 3. Existed (see FIG. 9A). Further, the side of the long hole intersections A ₁ and A ₁ that is close to the steering handle 15 and the vertical hole 4 on the opposite side are crossed with the horizontal long hole 3 in the neutral state. Are formed so that their lengths are different. That is, the length is formed so that the upper direction or the lower direction is different above and below the neutral line of the horizontally long hole 3 (see FIG. 9B).
[0035]
Next, as a third type of the second embodiment, in the long hole intersecting portion A ₁ , it is orthogonal to the longitudinal direction of one horizontal long hole 3 or vertical long hole 4 located on either the front side or the steering handle 15 side. The width dimension to be formed may be a long hole (commonly called a fool hole) having a large margin with respect to the diameter of the fastening shaft 5. In FIG. 7 (A), is larger and landscape hole 3 an elongated hole 4 of the long hole intersection A ₁ of the vehicle body front side. In FIG. 7B, only the vertically long hole 4 is enlarged. Moreover, you may give allowance to the width dimension of both the horizontally long hole 3 and the vertically long hole 4. Further, Vertical hole 4 of the long hole intersection A ₁ is not only the direction perpendicular to the axis of the steering shaft 10, or is inclined, also be arcuately. Tilt adjustment can be performed by the elongated hole crossing portions A ₁ and A ₁ provided at two locations along the axial direction of the steering shaft 10 in the bracket A.
[0036]
Further, depending on the length in the longitudinal direction of the horizontally long hole 3 and the vertically long hole 4 constituting the long hole intersecting portion A ₁ , telescopic adjustment and inclination adjustment of the operation surface of the steering shaft 10 can be performed. Each of the adjustments by the long hole intersection A ₁ can be performed regardless of the structure of the transmission means between the steering shaft 10 and the steering gear 11. In the above description, the rigid intermediate shaft 12 is used as an example of the transmission means, but two cables are installed between the steering shaft 10 and the steering gear 11 as the other transmission means. There are those that operate the steering gear 11 and those that use electric signal conversion as another transmission means.
[0037]
[Action]
The intermediate shaft 12 is a rigid shaft that can be expanded and contracted, and one end in the axial direction thereof serves as a rocking center portion 12c and is connected to the steering gear 11 side via a universal joint portion 13. The other axial end of the intermediate shaft 12 is connected to the steering shaft 10 via a universal joint portion 13. When adjusting the tilt of the steering handle 15, the connecting portion 12d of the intermediate shaft 12 moves along an arcuate locus with the swing center portion 12c as the swing center (see FIGS. 5 and 13).
[0038]
The steering shaft 10 moves in accordance with the arcuate locus of the connecting portion 12d, and the steering shaft 10 can be moved substantially vertically by the two long hole intersections A ₁ and A ₁ (FIGS. 5 and 5). 13). Thereby, the tilt adjustment of the steering handle 15 can be performed. The steering shaft 10 is, when moving according to a circular arc on the locus of the connecting portions 12d, by following the horizontally long hole 3 of the long hole intersection A _1, the steering shaft 10 is moved substantially coincides with the axial direction. Accordingly, the telescopic adjustment of the steering handle 15 can be performed within the range of the horizontally long hole 3.
[0039]
Support position of the tilt operation of the steering shaft 10, and the swing fulcrum by swinging center portion 12c, and a movable fulcrum consisting of the long hole intersection A ₁ is present. These fulcrums act independently or interact with each other to determine the operation of the steering shaft 10. Its movable fulcrum is present at any position in the elongated hole intersection A _1, optimal for the operation balance during position adjustment in freely (unlocked) state in tilt actuation direction. The swing fulcrum swings due to the movement of the steering shaft 10 at the time of tilt adjustment, or becomes the center when the steering shaft 10 operates in the vertical direction.
[0040]
At the time of the tilt operation, the steering shaft 10 is free (unlocked) in the tilt operation direction. At this time, the movable fulcrum in the position adjustment of the steering handle 15 exists at a place where an optimal operation balance can be obtained at the two long hole intersections A ₁ and A ₁ .
[0041]
Incidentally, the steering shaft 10 when moving in accordance with the swing locus of the connecting portion 12d for swing center portion 12c of the intermediate shaft 12, the steering shaft 10 in accordance with the Horizontal holes 3 of the long hole intersection A ₁ of the bracket A It moves in the axial direction (see FIG. 5).
[0042]
Next, the fixed bracket 1 fixed to the vehicle body, the movable bracket 2 sandwiched between the fixed bracket 1, the steering shaft 10 mounted on the movable bracket 2, and either the fixed bracket 1 or the movable bracket 2 A laterally long hole 3 formed on the other side of the fixed bracket 1 or the movable bracket 2, a fastening shaft 5 passing through the laterally long hole 3 and the longitudinally long hole 4, the steering shaft 10 and the steering gear. The intermediate shaft 12 is connected to the intermediate shaft 12 via a universal joint portion, and the intermediate shaft 12 is swingable. A movable bracket 2 is mounted in the fixed bracket 1 to connect the horizontally long hole 3 and the vertically long the range and the hole 4 intersects the elongated hole intersection a _1, the said long hole intersections a ₁ provided at two locations along the axial direction of the steering shaft 10, the length By using the steering handle position adjusting device that allows the fixed bracket 1 and the movable bracket 2 to be appropriately fixed by passing the fastening shafts 5 and 5 through the hole intersections A ₁ and A ₁ , the tilt position adjusting device The structure can be made extremely simple.
[0043]
More specifically, the fixed bracket 1 and the movable bracket 2 are each formed with either a horizontally long hole 3 or a vertically long hole 4. When the fixed bracket 1 and the movable bracket 2 are combined, the horizontally long hole 3 and the vertically long hole are combined. A long hole intersection A ₁ where 4 intersects is formed. The fastening shaft 5 is passed through the long hole intersection A _{1 so} that the fastening shaft 5 can be suitably tightened, and the steering shaft 10 is connected to the swingable intermediate shaft 12 so that the steering shaft 10 Tilt adjustment of the attached steering handle 15 is extremely stable operation by the swinging operation of the intermediate shaft 12 that does not expand and contract in the axial direction and the two long hole intersections A ₁ and A ₁ of the bracket A that supports the steering shaft 10. It can be done with a sense.
[0044]
Therefore, the tilt adjustment of the steering handle 15 mounted on the steering shaft 10 can be performed smoothly, the tilt adjustment range can be easily expanded, and an optional adjustment for that can be performed. In addition, since the fulcrum (movable fulcrum) portion can be firmly fixed in the same manner as the adjustment portion in the bracket A, the steering column can be firmly supported and fixed without generating vibration. In addition, a smooth tilt operation can be ensured without generating a tensile stress on the intermediate shaft 12 and the steering gear 11 during the tilt adjustment. In addition, the tilt operation range can be easily expanded in a limited range, and the optional adjustment can be sufficiently performed.
[0045]
While having such a structure, the configuration of the present invention is mainly formed by forming the horizontally long hole 3 and the vertically long hole 4 in the fixed bracket 1 and the movable bracket 2 respectively, and can have a very simple structure. And size reduction and weight reduction can be achieved simultaneously.
