[0005]
[Problems to be solved by the invention]
However, in the conventional automatic speed change operation device, the side shape of the push knob is often a curved surface (for example, the cross-sectional shape is an ellipse, etc.) mainly because of a demand for design. Since the inner peripheral wall of the insertion hole 103 of the lever knob 102 needs to have a shape that follows the shape of the side surface of the push knob 104, there are the following problems.
[0006]
That is, since the push knob 104 and the shift lever knob 102 are separately molded, when the push knob 104 is inserted into the insertion hole 103 of the shift lever knob 102 due to dimensional variations (dimensional errors) of individual parts, The shape of the sliding portion does not exactly match, and there is a risk of causing a sliding play in the push knob 104.
[0007]
It has been found that such dimensional variations of individual parts largely occur on the curved surface of each part mainly due to difficulty in measuring dimensions, etc. The side shape of the push knob 104 made of such a curved surface, the shape of the inner peripheral wall of the insertion hole 103, etc. In fact, the actual situation is that sliding play tends to occur. However, if the side surface shape and the insertion hole of the push knob are rectangular, the dimensional variation can be reduced and the sliding play of the push knob can be reduced. In many cases, the curved surface must be curved.
[0008]
The present invention has been made in view of such circumstances, and the side sliding portion of the push knob has a curved surface, and the inner peripheral wall of the insertion hole is formed in a shape following the side surface shape. An object of the present invention is to provide an automatic transmission for a vehicle capable of suppressing the sliding play of the push knob.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The vehicle automatic shift operating device according to the present embodiment is for performing a shift operation of an automatic transmission (automatic transmission) included in the vehicle. As shown in FIGS. 1 to 5, a shift lever (select lever) ) 1, a cover member 3, an escutcheon 17, a first bracket 8, and a second bracket 9.
[0014]
The shift lever 1 is formed with a shift lever knob H that can be gripped by the driver at the tip thereof, and is rotatable with respect to the cover member 3, the escutcheon 17, the first bracket 8 and the second bracket 9. It is a thing. In other words, the shift lever 1 is inserted and assembled into a rotation slot 3a formed in the cover member 3 as shown in FIG. 5, and the parking position (P), reverse position (R), drive position (D) and It rotates between the 2nd speed position (2) and performs a desired speed change operation on an automatic transmission (not shown).
[0015]
Further, as shown in FIG. 4, the shift lever knob H at the tip of the shift lever 1 is formed with a push knob 1a that can be pressed by the driver, and the shift lever is operated by pressing the push knob 1a. A rod 6 extending in the longitudinal direction of 1 is configured to be slidable downward, and a rod pin 20 (see also FIG. 8) is fitted and connected to the proximal end side of the rod 6. 6 and the rod pin 20 slide downward. A spring 77 is disposed on the base end side of the rod pin 20 in the shift lever 1, and always urges the rod 6 and the rod pin 20 upward. When the finger is released from the push knob 1a, these springs 77 are provided. The rod 6 and the rod pin 20 return upward.
[0016]
4 and 8, the lock pin 2 extends substantially perpendicular to the longitudinal direction of the rod pin 20, and the rod pin 20 and the slide within the shift lever 1 of the rod 6 and The lock pin 2 is also configured to be slidable in the vertical direction. That is, as shown in FIG. 8, a pin insertion hole 1b extending in the vertical direction is formed on the rotation base end side (lower side in the figure) of the shift lever 1, and the lock pin 2 is a pin insertion hole. It slides in the vertical direction along with the rod pin 20 along 1b and rotates together with the shift lever 1.
[0017]
As shown in FIGS. 1 and 8, the first bracket 8 is attached to one side surface (right side surface in FIG. 2) substantially parallel to the rotation direction of the shift lever 1. Three bolt holes 8a to 8c are formed. The erroneous operation prevention window 10 is formed at a position where one end (the left end in FIG. 4) of the lock pin 2 is inserted, and has a shape that restricts or allows the movement of the lock pin 2. Reference numeral 16 in FIG. 8 indicates a cushion material fixed to the upper edge of the erroneous operation preventing window 10, and reference numeral 18 indicates a shift lever cover that is inserted through the shift lever 1 and interlocked with the shift lever 1. Is shown.
[0018]
Specifically, the erroneous operation preventing window 10 has a shape as shown in FIG. 13, and when the lock pin 2 is in the upper position (the push knob 1a is not pressed), the shift lever When rotating 1 from the parking position (P) to the reverse position (R), a portion that contacts the lock pin 2 is formed, and the rotation of the shift lever 1 can be restricted. .
[0019]
That is, in order to perform a driver's conscious operation, the push knob 1a is pressed to move the lock pin 2 downward, so that the lock pin 2 does not come into contact with the erroneous operation prevention window 10, thereby shifting the shift lever. 1 is configured to allow rotation from the parking position (P) to the reverse position (R). From the same viewpoint, the shift lever 1 is rotated from the reverse position (R) to the parking position (P), from the neutral position (N) to the reverse position (R), and from the drive position (D) to the second speed position (2). Also when moving, it is necessary to press the push knob 1a.
[0020]
On the other hand, as shown in FIGS. 3 and 8, the second bracket 9 is attached to the other side surface (the left side surface in FIG. 2) substantially parallel to the rotation direction of the shift lever 1, and is attached to the outer side surface thereof. Are provided with a solenoid 11 and a regulating member 12 constituting a parking lock mechanism, and a forcible releasing means 13. Note that an opening 15 is formed in the second bracket 9 at a position where the other end (right end in FIG. 4) of the lock pin 2 is inserted. The opening 15 has a shape that allows the operation of the lock pin 2 ( (Substantially rectangular shape).
[0021]
The parking lock mechanism including the solenoid 11 and the regulating member 12 regulates or cancels the rotation of the shift lever 1 when the shift lever 1 is in the parking position (P) from the viewpoint of preventing sudden start. As shown in FIG. 14, the regulating member 12 is connected to an operation portion 11 a that expands and contracts by the operation of the solenoid 11. And in the state which the operation part 11a of the solenoid 11 extended, as shown in the figure, even if the front end surface 12a of the regulating member 12 abuts against the other end of the lock pin 2 and the push knob 1a is pressed, parking is performed. The lock pin 2 in the shift lever 1 at the position (P) is prevented from sliding downward.
[0022]
Further, when an electric signal is transmitted from the vehicle side to the solenoid 11 by recognizing that the driver has stepped on the brake pedal by a sensor or the like, the operation portion 11a of the solenoid 11 contracts. It rotates around the rotating shaft 12b. Accordingly, the front end surface 12a of the restricting member 12 also moves, and if the push knob 1a is pressed, the lock pin 2 can be slid downward, and the shift lever 1 is rotated from the parking position (P) to the reverse position (R). Can be allowed to move.
[0023]
By the way, when an electrical failure occurs in the vehicle, the operation unit 11a may not operate. Therefore, the second bracket 9 is provided with a forcible release means 13 that forcibly rotates the restriction member 12 and releases the restriction by the parking lock means regardless of the drive of the solenoid 11.
[0024]
As shown in the figure, the forcible release means 13 can swing about a shaft 13a, and has an operation surface 13b at one end and an action surface 13c at the other end. Then, when the lid 4 (see FIG. 5) formed on the cover member 3 is removed and the key K is inserted from the insertion hole 5 as shown in FIG. 3, the tip of the key K presses the operation surface 13b, The forcible release means 13 swings about the shaft 13a. By such swinging, the action surface 13c of the forcible release means 13 presses the protruding portion 12c formed on the operation portion 11a side, so that the regulating member 12 is moved in the same direction as when the operation portion 11a of the solenoid 11 contracts. It can rotate and the restriction by the parking lock mechanism can be released.
[0025]
Further, as shown in FIG. 7, three connecting members 9 a to 9 c each formed in a bar shape are extended from the inner side surface of the second bracket 9, and in the vicinity of the tips of the connecting members 9 a to 9 c. The male screw part is formed in. Moreover, each connection member 9a-9c is formed in the position corresponding to the bolt holes 8a-8c formed in the 1st bracket 8, and as shown in FIG. The first bracket 8 and the second bracket 9 are inserted by inserting the connecting members 9a to 9c through the bolt holes 8a to 8c and screwing the nuts Na to Nc to the male screw portions of the connecting members 9a to 9c. Thus, the rotation base end side of the shift lever 1 is sandwiched.
[0026]
Here, the connecting member 9c, which is one of the three connecting members 9a to 9c, is inserted into the rotation center hole 14 formed on the rotation base end side of the shift lever 1, thereby shifting the shift member 9c. The rotation axis of the lever 1 is formed. Thus, by using one of the connecting members as the rotation shaft of the shift lever 1, the number of parts can be reduced and the assemblability can be improved as compared with the case where a separate rotation shaft is provided.
[0027]
Moreover, as shown in FIG.4 and FIG.8, as for the 1st bracket 8 and the 2nd bracket 9, these lower parts are each bend-formed by the outside, respectively, and it is substantially L-shaped as a whole, and each bending part is A and B are configured to be fixed to the vehicle body. Accordingly, a base member or the like for fixing individual brackets can be eliminated, the number of parts can be reduced, and the manufacturing cost can be reduced. It is preferable that a bolt hole is formed in each of the bent portions A and B, and the bolt is inserted into the bolt hole and fixed to the vehicle body.
[0028]
According to the above-described automatic transmission operation device for a vehicle, the first bracket 8 in which the erroneous operation preventing window 10 is formed on one side surface on the rotation base end side of the shift lever 1, and the parking lock means (solenoid) on the other side surface. 11 and the restricting member 12) and the second bracket 9 provided with the forcible releasing means 13 are disposed, so that the second bracket 9 which does not depend much on the difference in the model can be used as it is.
[0029]
On the other hand, the push knob 1a disposed in the shift lever knob H according to the present embodiment has a side surface (side surface sliding portion) having an elliptical shape, as shown in FIGS. The inner peripheral wall of the insertion hole Ha through which the push knob 1a is inserted has a shape (that is, an elliptical shape) that follows the shape of the side sliding portion of the push knob 1a. Further, a push knob spring 19 is interposed between the push knob 1a and the shift lever knob H, and the push knob 1a is separated from the insertion hole Ha by the elasticity of the push knob spring 19 (that is, inserted). Always biased in the direction of jumping out of the hole Ha).
[0030]
However, in the state where the shift lever knob H is assembled to the rod 6, the tip of the rod 6 is inserted into the insertion hole 1ab formed on the base end side of the shift lever knob H as shown in FIG. The push knob 1a is prevented from popping out by the elasticity of the push knob spring 19. A taper 6a is formed at the tip of the rod 6, and a taper 1aa corresponding to the taper 6a is formed on the push knob 1a.
[0031]
Accordingly, when the push knob 1a is pressed in the direction in which the push knob 1a is brought close to the shift lever knob H (the arrow direction shown in FIG. 11 and FIG. 12), it slides in the insertion hole Ha, and the push knob 1a side taper 1aa Since the taper 6a on the rod 6 side functions as a cam, the rod 6 can be slid downward and the lock pin 2 can be moved downward to release the operation restriction of the shift lever 1 at a predetermined position. When the pressing operation on the push knob 1a is stopped, the rod 6 is returned to the upper original position by the spring 7 as described above, and the push knob 1a is also slid to the original position by the urging force of the push knob spring 19. Move back.
[0032]
Here, as shown in FIG. 9, the side surface sliding portion of the push knob 1a according to the present embodiment is formed with convex portions a to d each of which has a flat surface. More specifically, a pair of convex portions a and b provided at both ends of one straight line Lb orthogonal to the sliding direction of the push knob 1a and a pair provided at both ends of the other straight line La. Each convex part is formed in a total of four places with the convex parts c and d.
[0033]
Furthermore, as shown in FIG. 10, flat portions e to h are formed at positions corresponding to the convex portions a to d on the inner peripheral wall of the insertion hole Ha through which the push knob 1 a is inserted. When the pressing operation is performed, the flat surfaces of the protruding ends of the convex portions a to d and the flat portions e to h provided at positions corresponding thereto are slid while coming into contact with each other. Accordingly, it is possible to suppress the sliding play associated with the pressing operation of the push knob 1a.
[0034]
That is, as in the prior art, when the side surface sliding portion of the push knob remains a curved surface over the entire circumference and the insertion hole has a shape following the curved surface, due to dimensional variations between the push knob and the insertion hole, The push-knob side sliding portion and the inner peripheral wall of the insertion hole do not exactly match, and when the push knob is pressed, sliding play occurs, whereas in this embodiment, the push knob and the insertion hole Since each of the sliding portions is a flat surface, the respective dimensional variations can be made extremely small, and the sliding play can be suppressed.
[0035]
In addition, since the convex portions a to d are provided at both ends of the two straight lines La and Lb in the direction orthogonal to the sliding direction of the push knob 1a, each pair of convex portions (the convex portions a and b) And between the convex portions c and d) can be accurately performed, and sliding backlash can be further suppressed. Furthermore, since the protruding ends of the convex portions a to d form a flat surface, the sliding between the flat surfaces can be further suppressed at the time of sliding accompanying the pressing operation of the push knob 1a.
[0036]
By the way, as shown in FIG. 11, the shift lever knob H is formed by integrally forming an outer resin member H1 made of an outer soft resin and an inner resin member H2 made of an inner hard resin, and has an insertion hole Ha. The inner peripheral wall is formed on the inner resin member H2. From a part of the inner peripheral wall of the insertion hole Ha, an engaging claw 21 formed integrally with the inner peripheral wall extends toward the inner side of the insertion hole Ha.
[0037]
On the other hand, on the proximal end side of the push knob 1a, a locked portion 22 that can be locked with the engaging claw 21 is formed, and the push knob 1a is inserted into the insertion hole Ha via the push knob spring 19. In this state, the push knob 1a can be temporarily fixed. That is, in the shift lever knob H before being assembled to the rod 6, when the push knob spring 19 and the push knob 1a are inserted into the insertion hole Ha, the push knob 1a protrudes from the insertion hole Ha by the elasticity of the push knob spring 19. Therefore, in order to avoid this, the push knob 1a is temporarily fixed (temporarily fixed) by the engaging claw 21.
[0038]
Accordingly, since a separate temporary fixing work is not required until the shift lever knob H is assembled to the shift lever 1 (particularly, the rod 6), workability can be improved, and a separate dedicated temporary fixing part can be provided. Therefore, the number of parts at the time of temporary fixing can be reduced. The engaging claw may be formed at any other position in the insertion hole Ha of the shift lever knob H, but it is necessary to form the locked portion 22 at the position of the push knob 1a corresponding thereto. .
[0039]
Although the present embodiment has been described above, the present invention is not limited to this. For example, as shown in FIG. 15, in the side sliding portion of the push knob 1 a, one straight line Lb orthogonal to the sliding direction. The protruding ends of the pair of convex portions a ′ and b ′ provided at both ends of the pair and the pair of convex portions c ′ and d ′ provided at both ends of the other straight line La are arcuate (not flat). It may be.
[0040]
Even in this case, the protruding ends of the convex portions a ′ to d ′ slide on the flat portion of the inner peripheral wall of the insertion hole provided at a position corresponding to the protruding portions a ′ to d ′. It is possible to suppress the accompanying sliding play and accurately measure the dimension between the pair of convex portions (between the convex portions a ′ and b ′ and the convex portions c ′ and d ′). The sliding play accompanying the pressing operation of the push knob 1a can be further suppressed.
[0041]
Further, the number and positions of the convex portions formed on the side sliding portion of the push knob 1a are not limited to those in the above embodiment, and as shown in FIG. 16, at least the side sliding portion in the push knob 1a. The convex portions i to k may be provided at three locations, respectively, and the convex portions i to k may slide on the planar portion of the inner peripheral wall of the insertion hole at a position corresponding to the convex portions i to k. That is, it suffices to provide convex portions at at least three locations on the side sliding portion of the push knob 1a, and convex portions may be provided at five or more locations. However, it is necessary to form a flat portion as in the above embodiment at the position of the inner peripheral wall of the insertion hole corresponding to them.
[0042]
In addition, you may apply to the thing of the structure with which the bracket which hold | maintains a shift lever rotatably is integral. That is, in the present embodiment, the structure is such that the pivot side base end portion of the shift lever is sandwiched between the first bracket 8 and the second bracket 9, but is rotatably held by the integral bracket. A shift lever knob may be formed at the tip of the shift lever, an insertion hole as in this embodiment may be formed in the shift lever knob, and the push knob may be inserted to enable a pressing operation.
[0043]
【The invention's effect】
According to the first aspect of the present invention, since the convex portion slides on the flat surface portion by pressing the push knob, the side surface sliding portion of the push knob forms a curved surface and follows the shape of the side surface. Even in the case where the inner peripheral wall of the insertion hole is formed in a different shape, the sliding play of the push knob can be suppressed.
[0044]
According to invention of Claim 2, since the protrusion of a convex part comprises a plane, it becomes a slide between planes at the time of the sliding accompanying the press operation of a push knob, and it can further suppress sliding backlash.
[0045]
According to the invention of claim 3, since the convex portions are provided at both ends of each of the two straight lines in the direction orthogonal to the sliding direction of the push knob, the dimension between the pair of convex portions is accurately determined. And sliding backlash can be further suppressed.
[0046]
According to the invention of claim 4, the engaging claw formed integrally with the inner peripheral wall of the insertion hole is engaged with the engaged portion provided on the proximal end side of the push knob, so that the temporary provision of the push knob is achieved. Since it can be fixed, separate temporary fixing work and temporary fixing parts are not required until the shift lever knob is assembled to the shift lever, improving workability and the number of parts at the time of temporary fixing Can be reduced.
