Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift device for an automatic transmission for a vehicle, and more particularly, to a shift device that enables normal shift range switching and manual speed selection.

[Conventional technology]

The shift pattern of the shift operation unit in the conventional automatic transmission includes parking (hereinafter referred to as “P”), reverse (hereinafter referred to as “R”), neutral (hereinafter referred to as “N”), and drive (hereinafter referred to as “D”). In addition to each range, the second pattern (hereinafter, referred to as “S”) and the low (hereinafter, referred to as “L”) range for operating an engine brake on a mountain road or the like are configured by an I pattern arranged along a serial path.

In the current automatic transmission, ranges of P, R, N, D, S, and L are determined by mechanical switching of a manual valve in a hydraulic servo control circuit that operates the friction engagement element. And electronically controlling the solenoid valve in the hydraulic servo control circuit in accordance with the vehicle speed and the throttle opening to select a specific speed stage within the predetermined range. Is performed. Then, in the D, S, and L ranges corresponding to the traveling ranges, speed selection in each range is automatically performed.

On the other hand, recently, in order to realize driving that is more suited to human sensitivity, intentional selection of a specific speed gear has been made in consideration of the driver's will and the driving fun. Shifting devices have been developed that include a manual speed-selecting mechanism that enables this.

An example of such a shift device is disclosed in Japanese Unexamined Patent Publication No. 2-8545.
There is a technique disclosed in Japanese Unexamined Patent Publication (Kokai) No. H11-26095. This device performs a conventional automatic shift by rotating a shift lever in a first shift path along a normal I pattern, and moves the shift lever through a lateral path to a second shift parallel to the first shift path. After switching to the road, the vehicle is turned in the shift road to perform manual speed selection. In this device, the turning of the shift lever in the first shift path is mechanically transmitted to the transmission, and the turning of the shift lever in the second shift path is detected by a sensor constituting a switch means. And transmitted electrically to the transmission.

[Problems to be solved by the invention]

However, in the shift device, when the connection between the shift lever and the entrainment member that transmits the movement in the first shift path to the transmission is released due to the shift of the shift lever to the lateral path, the entrainment member is disengaged. Since there is no means for restraining and holding the shift lever at the
There is a possibility that recombination when returning to the shift path may lose smoothness due to displacement.

In view of such circumstances, the present invention provides a manual valve of an automatic transmission in which a return from a manual speed selection operation by a shift lever to an automatic speed change operation is smoothly performed, and furthermore, an impact or the like applied to a vehicle body during the manual speed selection operation. It is an object of the present invention to provide a shift device with a manual speed-selecting mechanism for an automatic transmission for a vehicle, which prevents inadvertent switching.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a stationary member attached to a vehicle body, and is supported swingably around a first axis provided on the stationary member, and is connected to a manual valve of an automatic transmission. A second shaft is provided orthogonal to the first shaft on a swing retainer and a cross sleeve rotatably provided on the first shaft, and is rotatable about the first and second shafts. A shift lever supported by the shift lever, wherein the shift device can be switched between automatic transmission and manual selection by rotation of the shift lever around the second axis. The swing lever is supported by the swing retainer, and slides with respect to the swing retainer by the rotation of the shift lever about the second axis to disengage from the stationary member, and fixes or releases the swing retainer to or from the stationary member. Rock pre Has a door, the lock plate,
The shift lever has a long hole through which the shift lever comes into contact with a lock plate in the long hole when rotating about the second axis, and the shift plate is engaged with the lock plate to thereby lock the lock plate. The swing retainer is slid and engaged with the stationary member, and the swing retainer is fixed to the stationary member.

Further, the shift lever and the swing retainer are engaged with each other about rotation about the first axis in a state where the lock plate is not engaged with the stationary member. The engagement of the shift lever and the swing retainer with respect to rotation about the first axis is released, and the shift lever moves along the first hole of the lock plate along the first hole of the lock plate. It is possible to rotate around an axis, and select a plurality of gear positions for the manual speed selection by the rotation.

Further, the swing retainer has a pair of grooved flanges extending in the second axial direction and supporting the lock plate, and the lock plate is rotated by rotation of the shift lever around the first axis. It is also possible to adopt a configuration in which the shift lever is engaged with the grooved collar, is connected to the swing retainer, and is guided by the grooved collar by the rotation of the shift lever around the second axis to slide.

The stationary member may have a hole, and the lock plate may have a slide restricting surface that is engaged and disengaged from the hole by rotation of the shift lever about the second axis.

[Action and effect of the invention]

According to the configuration of the first aspect, the shift lever is inserted into the long hole provided in the lock plate, so that when the shift lever rotates around the second axis, the shift lever comes into contact with the lock plate in the long hole. , The lock plate is integrally linked with the shift lever, and switching between automatic transmission and manual selection can be performed by rotation of the shift lever around the second axis. The lock plate supported by the swing retainer is The rotation about the second axis slides with respect to the swing retainer to disengage from the stationary member, and fixes or releases the swing retainer to or from the stationary member. Therefore, when switching from automatic transmission to manual selection by rotation of the shift lever around the second axis, the swing retainer connected to the manual valve is fixed to the stationary member by the lock plate, so that the impact applied to the vehicle body is reduced. The manual valve is not inadvertently switched due to the like. Also, when returning from the manual speed-selecting operation to the automatic speed-change operation, since the swing retainer is positioned, smooth re-engagement between the shift lever and the swing retainer can be ensured. In addition, according to this configuration, the displacement of the shift lever is directly transmitted to the lock plate, so that the swing retainer can be stably fixed to and released from the stationary member without fear of deterioration with time. According to the configuration, when the lock plate is not engaged with the stationary member, the shift lever and the swing retainer are engaged with each other for rotation about the first axis, so that the shift lever and the swing retainer are interlocked. And the shift lever can be rotated around the first axis along an elongated hole provided in the lock plate while the lock plate is engaged with the stationary member. A plurality of gear positions for speed selection can be selected.

Further, according to the configuration of the third aspect, the lock plate is reliably guided by the grooved flange provided on the swinging retainer, and can be slidably linked only to the rotation about the second axis.

According to the structure of the fourth aspect, the slide restricting surface of the lock plate is engaged with the hole of the stationary member, and when the shift lever rotates around the first axis for manual speed selection, it is swung. The retainer can be securely locked.

The contact member 65 is sandwiched between the two working ends 661 and 662 of the torsion spring 66 having a coil wound around the rear outer periphery of the sleeve 62 to support them. And a torsion spring contact member 331 similar to that described above is provided to protrude forward. Therefore, when the shift lever 3 is rotated left and right with respect to the cross sleeve 6, the abutting member 331 is moved to both the operating ends 6 of the torsion spring 66.
While one of the working ends is separated from the other, the other of the working ends is supported by the contact member 65, so that the neutral return force of the torsion spring 66 acts on the shift lever 3.

It is connected to the lever 83. A detent lever 84 is attached to the other end of the manual shaft 82, and a manual valve 86 sliding in the valve body 85 is connected to the detent lever 84 via a rod 87. A cam notch 841 is formed on the peripheral surface of the detent lever 84, and a detent spring 88 is provided with the working end abutting on the cam notch 841.

The switch box 4 is screwed to the bracket 212 of the main body 21. FIG. 4 is an exploded perspective view showing details of the switch box.
Comprises a case 41, a slider 42 sliding inside the case 41, and a printed circuit board (hereinafter, referred to as a "PC board") 43. A contact plate 45 is attached to the slider 42, and the case 41 and the slider 42 Slider guide between
44 are interposed. The slider guide 44 slides back and forth in the case 41 by being fitted and guided in a guide groove 412 formed in the lower surface of a not-shown projection case 41 projecting from the upper surface thereof, and the slider 412 is moved from the case opening 411 through the case opening 411. A stopper for preventing the slider 42 from being pulled out upward and guide means for guiding the slider 42 to the left and right are configured. The slider 42 has a joint portion 422 that rises from the upper surface of the block portion 421 and protrudes to the outside through the case opening 411. A spherical surface 423 (see FIG. 1) formed inside the slider 42 has a spherical shape of the operating arm 35. The part 351 is slidably fitted. The block portion 421 of the slider 42 is provided with two notches 422 to 424 at the front and one at the rear, and the projections 451 to 453 of the contact plate 45 are fitted into these notches, and the projections 451 to 453 are provided.
The cut-and-raised portion (one of which is denoted by reference numeral 454) is provided with the stepped portions of the cutouts 422 to 424 (one of which is denoted by reference numeral 454).
425). Three contacts 455 to 457 are formed on the lower surface of the contact plate 45 at the apexes of the triangle so as to project therefrom. Behind these contacts, the contacts are accommodated in holes formed in the block portion 421 of the slider 42. A spring 46 is provided in a compressed state.
Therefore, the three contacts 455-4 of the contact plate 45
57 is pressed against the PC board 43 by an appropriate spring force. Although not shown, a connection terminal is provided in a step portion behind the case 41.

Fig. 5 shows the circuit pattern of the PC board and the contacts 3
It is a top view which shows the positional relationship of this contact point, as shown in the figure, the PC board 43 has eight conductor parts 431,432,
433a, 433b, 433c, 434, 435, 436 are provided. The center conductor 431 always contacts one of the contacts of the contact plate 45, and the other conductor contacts one of the remaining two contacts due to the movement of the contact plate 45. In this example,
The conductor portion 432 is for the first speed, 434 is for the second speed, 435 is for the third speed, 436 is for the fourth speed, and the contact 433a is divided into three,
433b and 433c are for D. Each contact is connected to P,
At the R, N, and D positions, there is a positional relationship indicated by D with a circle in the figure.

Next, the operation of the shift device thus configured will be described step by step.

6 (a) to 6 (d) are side views showing the movement of each member of the shift device in an overlapping manner to show the movement of the members, and FIG. 7 is a plan view showing the operation of the lock plate of the shift device. In FIG. 7, the inclination of each member caused by the inclination of the swing retainer is ignored.

FIGS. 6 (a) and 7 (a) show the P position, in which the swing retainer 2 is in the state of being inclined forward most, and the shift lever 3 is moved right and left by the lock plate 5. The direction is positioned, and it is located at the connection part of the H-shaped hole 221 of the gate plate 22. Although not shown in the figure, the plate pin 71 of the inhibit plate 7 is in the inhibit state by fitting into the foremost notch of the cam surface of the inhibit hole 123 shown in FIG.

When the shift lever 3 is pulled backward while pressing the knob button from the P position, the upper edge 75 of the inhibitor plate 7 is pushed downward by the depression of the inhibit pin 34, and the inhibitor plate 7 is inserted into the slot 72 by the guide post. The guide pin 213 descends, and the plate pin 7 is inserted into the inhibit hole 123.
Off the foremost notch on the cam surface. Since the shift lever 3 and the gate plate 22 are engaged in the front-rear direction at the central connection portion of the H-shaped hole 221, the swing retainer 2
Swings rearward together with the shift lever 3 and reaches the D position shown in FIG. 6B through the R position and the N position. During this time, the rotation of the shift lever 3 in the left-right direction is controlled by the rotation restricting surface 51 of the lock plate 5 and the main body 12 as shown in FIG.
Is regulated by sliding contact with the inner surface of the side wall. By this operation, as shown in FIG.
Swings back and forth around the left and right axis X, and pushes out the control rod 81 connected to the lower end of the outer lever.
83 swings counterclockwise in the figure as shown by the arrow, and as a result of swinging the manual shaft 82 and the detent lever 84 in the same direction to retract the rod 87, the manual valve 86 is switched. The moderation in this operation is
It is given by the spring force of the detent spring 88 that opposes the operation of the detent lever 84. The operation so far is not particularly different from the operation of the shift device of the conventional automatic transmission.

When the shift lever 3 reaches the position D, the rotation restricting surface 51 of the lock plate 5 becomes a hole 121 formed in the side wall of the main body 21.
Therefore, the right and left rotation regulation of the lock plate 5 is released, and the rotation is allowed.

To select the first speed at this position, use the shift lever 3
To the left, and then push forward. In this tilting operation, the shift lever 3 pushes the lock plate 5 to the left, so that the swing restriction surface 52 is engaged with the swing lock surface 122 of the hole 121 of the main body 12 by sliding to the left. Then, the forward and backward swing of the swing retainer 2 is regulated, and only the shift lever 3 is not regulated. During this operation, the spherical portion 351 of the operation arm 35 fixed to the shift lever 3 is
Slider 42 to the left. At this time, since a neutral return spring force is applied to the shift lever 3 by the torsion spring 66 (see FIGS. 1 and 2A and 2B), the same resistance as the conventional manual shift device is applied. Informed to the driver. 7 (b), the connecting portion 32 of the shift lever 3 moves forward along the long hole 53 of the lock plate 5, and the slider of the switch box 4 moves forward. The plunger 641 of the crossing sleeve 6 moves from the center notch of the cam surface of the detent cam 223 to the front notch over the middle mountain, and the plunger lifting spring at that time is moved. Is transmitted to the driver as a sense of moderation, and when switching from the P position to the D position, a shift feeling similar to that obtained by the detent spring 88 and the cam notch 841 (see FIG. 3) is obtained. be able to. Naturally the detent plunger mechanism 64
And the detent cam 223 perform the detent function, and hold the shift lever 3 at the first speed position. In both of these movements, the slider 42 of the switch box 4 moves to the left front, so that each contact moves as shown in FIG.
The contact 456 of the contact plate 45 contacts the conductor 432,
The conductor portion 431 and the conductor portion 432 conduct through the contact point 457, and the connection relationship is such that the first speed signal is output. On the other hand, since the manual valve connecting member 23 shown in FIG. 3 is immovable due to the restraint of the swing retainer 2 on the stationary member 1, the switching of the manual valve 86 via the control rod 81 does not occur.

Next, returning to FIGS. 6 and 7, in order to select the second speed, the shift lever 3 is tilted to the left and then pulled backward. In this tilting operation to the left, the forward and backward swing of the swing retainer 2 is regulated as described above, and only the shift lever 3 is not regulated. During this operation, the spherical portion 351 causes the slider 42 of the switch box 4 to slide to the left. 7 (c), the connecting portion 32 of the shift lever 3 moves rearward along the long hole 53 of the lock plate 5, and the slider of the switch box 4 moves. Move 42 backward. With both these movements, each contact point of the contact plate 45 shown in FIG. That is, since the contact 456 moves to the rear left, the conductor 431 and the conductor 434 are electrically connected via the contact 456 and the contact 457, and the connection is such that the second speed signal is output. Also in this case, since the manual valve connecting member 23 is immovable due to the restraint of the swing retainer 2 on the stationary member 1, the manual valve 86 is not switched through the control rod 81.

The selection of the third speed is a point-symmetrical movement about the D position as in the case of the second speed, and the lever is tilted rightward from the D position,
Next, an operation of pushing forward is performed. The operation and function of each member at this time is apparent from the above-described operation description, and a description thereof will be omitted in order to avoid redundancy. However, the positions of the shift lever 3 and the lock plate 5 are shown in FIG. c) and FIG. 7 (d), the slider 42 of the switch box 4 takes the forward right position, the contacts of the contact plate 45 take the path of, and the connection relation for outputting the third speed signal. Becomes

The selection of the fourth speed is a point-symmetric movement with respect to the case of the first speed with respect to the D position, and the position of the shift lever 3 is
The position is as shown in FIG. 6 (d). In this case, the slider 42 of the switch box 4 assumes the right rear position, the contact of the contact plate 45 assumes the position of, and the connection relationship outputs the fourth speed signal.

The speed selection signal obtained in this manner is processed in the same manner as a speed change signal output according to the vehicle speed and the throttle opening in the D range in a normal automatic transmission, and is used for controlling the solenoid valve for speed change.

As described above in detail, in this shift device, the left and right ears of the lock plate 5 formed in a cross shape function as a guide unit for the movement of the shift lever 3 along the I pattern during automatic shifting, and Since the rocking retainer 2 also functions as a locking means at the time of manual speed selection operation, a single member having two functions achieves compactness of the device. Further, since the shift device can be accommodated in the center console 100 (see FIG. 6 (a)) of the vehicle by such a related arrangement of the lock plate 5 and the stationary member 1, it is necessary to consider the appearance. Not only can a sufficient strength as a lock mechanism be secured, but also the upper plate 101 of the center console 100 has a strength compared to a conventional one in which the upper plate of the center console 100 must have strength and be used as a guide means. A secondary effect that can eliminate design constraints is also obtained. Further, according to the switch arrangement of this embodiment,
By attaching the switch box 4 to the swing retainer 2,
Since the relative movement between the switch box 4 and the shift lever 3 during the movement of the shift lever 3 between the P, R, N, and D positions can be eliminated, and the stroke required for the switch contacts can be minimized. Has also achieved miniaturization.

As described above, the present invention has been described in detail based on one embodiment. However, the present invention is not limited to only the disclosed contents of the above-described embodiment, and various specific details may be included within the scope of the claims. Needless to say, the present invention can be implemented by changing the configuration.
