BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission operating device for an automobile. For more details, push-pull control
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission operating device that uses a cable (hereinafter referred to as a cable) as a means for transmitting an operating force.

[0002]

2. Description of the Related Art In recent years, as a remote control means for a transmission in a small FF type passenger car, an FR type or RR type bus, a truck, etc., it is lightweight, low in cost, and relatively freely selectable in its mounting position. A cable type transmission operating device (hereinafter, referred to as a device) having the above is adopted.

For example, as shown in FIG. 8, rods 51 and 52, which are respectively connected to two cables (not shown), are arranged in parallel with each other, and one of these rods 51 and 52 is arranged. The change levers 53 are operated independently of each other.

That is, when the change lever 53 is tilted in the left-right direction (arrow PQ direction), the select rod 51 is pushed / pulled in the extending direction to perform the select operation of the transmission. The shift rod 52 is pushed and pulled in the front-rear direction by tilting in the direction of arrow R-S) to shift the transmission.

In the device shown in FIG. 8, a change lever 53 is connected to a frame via a ball joint 54, and a pair of rods 51 and 52 are fixed to a frame (not shown) to a cable cap (not shown). Guide pipe 5 rotatably connected at its base (not shown)
It is slidably guided by 5, 56. The shift cable is connected to the change lever 53 via one rod 52, and the select cable is connected to the first arm 58 of the bell crank 57 via the other rod 51.

The bell crank 57 is rotatably connected to the frame, and the second arm 59 of the bell crank 57 is rotatably attached to a shaft 61 connected to a ball member 60 of a ball joint 54 of the change lever 53. And they are connected so that they can escape in the axial direction.

[0007]

Generally, an attempt is made to push and pull two cables arranged in parallel with each other by tilting the change lever extending in the front-rear direction and the left-right direction in a direction perpendicular to the cables. In this case, the cable can be pushed and pulled directly in the direction in which the cable extends, that is, in the front-back direction (arrows R and S in FIG. 8), but in the left-right direction (arrows P and Q in FIG. 8) crank
It is necessary to change the operation direction through a direction changing mechanism such as 57.

Therefore, the structure becomes complicated and large, and further, it is necessary to improve the working accuracy in order to reduce the sliding resistance of the ball joint and to select a material having a small friction coefficient, resulting in an increase in cost. There is.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a transmission operating device having a very simple structure, a small loss of force transmission, and a low production cost. And

[0010]

A transmission operating device according to the present invention comprises: (a) a frame having a box-shaped holding portion on its rear end side; and (b) a frame extending in the front-rear direction of the frame. And (c) the holding portion so as to be rotatable about a first axis that obliquely intersects a plane perpendicular to the front-rear axis of the frame. A select shaft having both ends supported by a first locking piece protruding from a part thereof and having a substantially annular portion such as forming a window, and (d) extending in the left-right direction of the frame and A shift shaft, both ends of which are supported in an annular portion of the select shaft so as to be rotatable about a second axis that intersects the first axis, and a shift shaft provided with a second locking piece in a part thereof, and (e) the shift Change projecting vertically on the shaft (F) The free end of the select operation member is rotatably connected to the first locking piece, and (g) the free end of the shift operation member is rotated to the second locking piece. A transmission operating device that is freely connected.

The first axis may be at an angular position obtained by rotating the horizontal axis of the frame about the vertical axis (that is, in the horizontal plane), or by rotating the front-back axis of the frame about the horizontal axis. It may be in an angular position.

That is, in the present invention, the first axis may extend in a direction which intersects the plane orthogonal to the front-rear axis at an angle as described above.

The first locking piece is in a plane that intersects the first axis substantially at a right angle and is substantially perpendicular to the front-rear axis of the frame, and the second locking piece substantially extends with the second axis. Preferably in a plane that intersects with and substantially intersects the anteroposterior axis of the frame.

Each of the select operation member and the shift operation member comprises a pipe whose one end is connected to the front end of the frame by a spherical joint, and a rod which is slidably inserted into the pipe. One end of each rod. Is preferably connected to the select operation cable and the shift operation cable.

Further, it is preferable that the first axis and the second axis intersect obliquely at an angle of 35 to 55 °, especially 45 °.

The front-rear, up-down, left-right directions and front-rear axis, left-right axis, and
The expressions such as the vertical axis are merely expressions for clarifying the arrangement relationship of each element, and have no relationship with each direction of the automobile.
For example, the front-back direction of the frame may be aligned with the left-right direction of the automobile.

[0017]

When the change lever is tilted to the left or right (select operation), the rotation of the select shaft around the first shaft and the rotation of the shift shaft around the second shaft are combined, whereby the change lever moves in the left and right directions. Can be tilted.

As described above, when the select shaft rotates about the first axis, the first locking piece also swings about the first axis. At that time, the select operation member is effectively displaced by the amount of the locking piece in the front-rear direction, and the select operation is performed. Note that the horizontal or vertical displacement does not affect the select operation.

Further, as described above, the second locking piece is also swung to the left or right as the change lever is tilted to the left or right, but this causes the shift operation member to be hardly displaced in the front-rear direction. Therefore, effective operation is not performed in the above direction, and only select operation is performed after all.

When the change lever is tilted back and forth (shift operation), the shift shaft rotates about the second axis, and the second locking piece only swings in the front-back direction. Pushing and pulling in the direction, the shift operation is performed. At this time, the select shaft does not rotate around the first axis, and therefore the first locking piece does not swing, so that the select operation member is not pushed or pulled.

When the shift operation is performed after the selection operation is once performed, the second axis is tilted in the anteroposterior direction with some deviation from the in-plane in the vertical and horizontal directions (in the plane perpendicular to the longitudinal axis).
Since it is small, it does not substantially affect the shift operation at that position.

As described above, in the device of the present invention, since the select shaft inclined with respect to the extending direction of the cable converts the lateral movement of the change lever to the front-back direction, the bell crank or the like is do not need.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the device of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing an embodiment of the device of the present invention, FIG. 2 is a plan view of the device of FIG. 1, and FIGS. 3 to 4 are change levers at the time of selecting operation of the device of FIG. And a plan view showing the movement of the cable, FIGS. 5 to 6 are plan views showing the movement of the change lever and the cable during the shift operation of the apparatus of FIG. 1, and FIG. 7 is another embodiment of the select shaft of the apparatus of the present invention. It is a skeleton diagram showing.

In the apparatus shown in FIGS. 1 and 2, reference numeral 1 is a mounting frame fixed to a tunnel case or the like between the driver's seat and the passenger seat of an automobile.

On the front wall surface 2 of the frame 1, one end of each of a select cable 3 for performing a selecting action and a shift cable 4 for performing a shifting action is arranged in the front-rear direction of the frame 1 so as to extend substantially horizontally. ing. The conduits 5 and 6 of the select cable 3 and the shift cable 4 are fixed to the wall surface 2 with cable caps 7 and 8, for example.

As shown in FIG. 2, the cable cap 7,
Socket-shaped recesses 9 and 10 are formed at one end of the guide pipe 8, respectively, and the enlarged portions 13 and 14 provided at one end of the guide pipes 11 and 12 are tiltably received like a ball joint. One rod in each of the guide pipes 11 and 12
One end side of 5, 16 is inserted slidably and rotatably around its own axis. One ends of the rods 15 and 16 are fixed so as to be continuous with the inner cables 17 and 18 of the select cable 3 and the shift cable 4.

The cable cap 7, the guide pipe 11 and the rod 15 on the side of the select cable constitute the select operation member referred to in the claims, and the cable cap 8, guide pipe 12 and rod 16 on the side of the shift cable are It constitutes a shift operation member.

On the side opposite to the wall surface 2 of the frame 1, a box-shaped holding portion 19 for holding a select shaft 20, a shift shaft 21, a change lever 22 and the like, which will be described later, is provided with a front and rear shaft of the frame 1 ( That is, it is installed at an angle of about 45 ° in the horizontal plane with respect to the wiring directions of the cables 3 and 4. Since the holding portion 19 has a box shape, even if the change lever 22 is repeatedly operated, there is no fear of bending or damage, which contributes to prevention of erroneous operation and improvement of durability.

In the holding portion 19, both ends (both ends of a straight line passing through substantially the center of the window) are supported so that the select shaft 20 which is substantially annular so as to form the window can be freely rotated. Has been done. Below, the select shaft 20
The rotation axis of is referred to as the first axis I.

In the window-shaped space 20a of the select shaft 20, a shift shaft 21 is rotatably supported at an angle of about 45 ° with respect to the rotation axis of the select shaft 20. Therefore, the shift shaft 21 is arranged substantially at right angles to the wiring direction of the cables 3 and 4.
The rotation axis of this shift shaft 21 is called the second axis II.

A change lever 22 extending upward is fixed to a substantially central portion of the shift shaft 21 so that the change lever 22 can be tilted around the second axis II.

On the other hand, the select shaft 20 has a first arm.
23 is projected downward, and the shift shaft 21 also has a second
An arm 24 (see FIG. 1) is provided so as to project downward.
In this embodiment, the shift shaft 21 and the change lever
Although the 22 and the second arm 24 are integrally formed, there is no particular limitation, and they are manufactured separately, and the shift shaft 21 is provided with the change lever 22 and the second arm.
You may attach 24 and later.

The free end of the first arm 23 is rotatably connected to the end of the rod 15 of the select operating member by a ball joint or the like, and the free end of the second arm 24 is connected to the rod 16 of the shift operating member. The ends of are also rotatably connected with a ball joint or the like.

Next, the operation of the device constructed as above will be described.

First, the select operation in the directions of arrows AB (right and left) shown in FIGS. 1 and 2 will be described.

An important point of the present invention is that the rotation of the select shaft 20 around the first axis I and the shift shaft 21 corresponding thereto are prevented even though there is no rotation axis in the front-back direction, that is, the direction in which the cable extends. By combining with the rotation around the second axis II, the change lever 22 can be tilted in the left-right direction, and by this, the rotation around the first axis I is converted into the forward-backward movement of the first arm 23. That is the point.

When the change lever 22 is tilted in the direction of arrow A from the neutral position shown in FIG. 3, the change lever 22 is brought into the state shown by the solid line in FIG. That is, the tilting in the A direction is accompanied by rotation of the select shaft 20 around the first axis in the arrow E direction. As a result, the first arm 23 protruding from the select shaft 20 swings in the combined direction of the arrow B direction and the arrow D direction. The internal measure 17 of the select cable 3 is pulled in the F direction by the swing of the arrow D direction component.

When the above select shaft 20 rotates in the E direction, the change lever 22 is originally tilted to the position shown by the chain double-dashed line, but normally the change lever is an H-shaped gate or the like. As a result, the operator moves in the direction of arrow A according to the intention of the operator and comes to the position indicated by the solid line. Therefore, tilting of the change lever 22 in the A direction is accompanied by rotation of the shift shaft 21 around the second axis II in the arrow G direction. However, since the second arm 24 projecting from the shift shaft 21 swings only in the left-right direction (however, in the direction of arrow B) like the change lever 22, the inner cable 18 of the shift cable 4 is not pushed or pulled. .

In this way, the inner cable of the select cable 3
Only 17 is pulled in the direction of arrow F, and the inner cable of the shift cable 4
18 hardly moves.

Even when the change lever 22 is tilted in the same direction as the left and right arrow B, the select shaft 20
And the rotation of the shift shaft 21 is interlocked, and only the inner cable 17 of the select cable 3 is pushed in the J direction, and the inner cable 18 of the shift cable 4 hardly moves.

By the way, when the change lever 22 is tilted in the direction of arrow A by 7 to 10 °, the rotation angle around the first axis I is 10 to 1.
It becomes 4.5 °, and the rotation angle around the second axis II becomes 7 to 10 °.

Next, a shift operation performed by tilting the change lever 21 of FIG. 1 in the direction of arrow C or D will be described.

When the change lever 22 is tilted further from the neutral position or from the position tilted in the direction of arrow A or B in the direction of arrow C, the change lever 22 shifts the shift shaft 21 as shown by the two-dot chain line in FIGS. Since it rotates as an axis, the second arm protruding from the shift shaft 21 at the same time
On the contrary, 24 swings in the direction of arrow D. Thereby, the inner cable 18 of the shift cable 4 is pulled in the arrow K direction via the rod 16 connected to the second arm. At that time, since the change lever 22 only rotates around the second axis II, the select shaft 20 is not rotated. Therefore, during the shift operation, the select rod 15 and the inner cable 17 of the select cable 3 are hardly pushed or pulled.

On the other hand, when the change lever 22 is tilted in the direction of arrow D in FIGS. 5 to 6, only the inner cable 18 of the shift cable 4 is pushed in the direction of arrow L by the same procedure. The inner cable 17 of the select cable 3 hardly moves. In this way
A shift operation is performed.

In the apparatus shown in FIGS. 1 and 2, the first axis I and the second axis I
The axis II intersects at an angle of 45 °, but the intersecting angle can be generally selected in the range of 35 to 55 °.

In the apparatus of FIGS. 1 and 2, the first axis I is set at a position which is swung to the left and right in a horizontal plane (a plane perpendicular to the vertical axis (Z-Z axis in FIG. 6)). Arrow S _{1 in} FIG.
S ₂ direction), for example, as shown in FIG. 7, the front and rear shaft (Y
-Y axis), Soku substantially in a vertical plane including the axis along the wiring direction of the cable before the uplink (arrow S ₃₎ or Maekudari (arrow S ₄₎
It may be set in a tilted position,
Further, the direction may be a combination of both.

In short, since the first axis only needs to have a component in the front-rear direction so that the select operation can be performed, it intersects with a plane at right angles to the front-rear axis (Y-Y direction). Any direction may be used, and the same effect can be obtained regardless of the direction.

It should be noted that the locking piece to which the select operation member is to be connected should be in a plane intersecting the front-rear axis and intersect the first axis, but it is substantially perpendicular to the first axis. Further, if it is provided in a plane substantially orthogonal to the front-rear axis, it is efficient because the front-rear axis direction component is maximized during the selection operation.

In any case, the second axis is parallel to the left-right axis (XX axis).

In the embodiment shown in FIGS. 1 and 2, the change lever 22 and the first arm 23 are deviated from the intersection of the first axis and the second axis, but the position is not particularly limited.
The change lever 22 and the first arm portion 23 may be provided on a straight line including the intersection. By doing so, there is an advantage that the lateral movement of the inner cable 18 of the shift cable 4 due to the selection operation can be minimized.

In the embodiment of FIGS. 1-2, the first arm 23
Is provided on the lower side of the select shaft 20, but may of course be provided on the upper side. Further, also in the embodiment of FIG. 7, the first arm 23 may be provided so as to project in either the left or right direction.

[0053]

In the device of the present invention, since the select shaft is annular, the shift shaft is strongly supported, and since the frame holding portion is box-shaped, the change lever and each shaft are supported. Becomes stronger and the durability is improved. Further, since the bell crank is not interposed, the structure is extremely simple, which results in a compact outer shape and a low production cost.
