Description

  The present invention relates to a technical field of a transmission shift device that shifts a shift stage of a transmission and a transmission including the same, and more particularly to a technical field of a transmission shift device and a transmission that are used in a transmission having a dual clutch. .

  Conventionally, as a transmission, a so-called dual clutch type transmission using a pair of first and second clutches has been proposed (see, for example, Patent Documents 1 and 2). In this dual clutch type transmission, the connection and disconnection of the first and second clutches are selectively switched. Then, with respect to the shift stage of the first shift line on the first clutch side that is connected, the shift stage to be shifted next is set in advance at the shift stage of the second shift line on the other second clutch side that is not connected. When the condition of the gear stage to be prepared and shifted next is established, the first clutch is disconnected and the second clutch is connected. As a result, in order to shift the gear position, the clutch is disengaged compared to the one-clutch system in which the set gear position is disengaged by making the clutch disengaged, and then the next gear position to be shifted is set and the clutch is connected. There is no torque loss phenomenon that occurs inside, and smooth shifting is possible. In such a dual clutch type transmission, one shift stage can be set simultaneously for different shift lines, but two different shift stages cannot be set simultaneously for the same shift line.

The transmissions described in Patent Documents 1 and 2 include a shift shift device. As shown in FIG. 5, these shift shift devices have a shifter a that is rotatable and linearly movable in the axial direction, and a shift block b that is linearly movable in the left-right direction in FIG. . The shifter a includes a cylindrical rotation shaft c, a shift lever d integrally projecting in the radial direction on the rotation shaft c, and a position shifted radially from the rotation shaft c and in the axial direction from the shift lever d. And a neutral return lever e projecting integrally therewith. On the other hand, the shift block b has a shift-side recess f into which the shift lever d can enter, and a neutral return-side recess g into which the neutral return lever e can enter. The shift-side recess f has first and second shift-side pressed portions h, i with which the shift lever d can come into contact, and the neutral return-side recess g has first and second neutral return-side pressed portions. It has parts j and k.

Then, the shifter a rotates so that the shift lever d becomes the first and second shift side pressed portions h,
When one of i is pressed, the shift block b moves to the gear position setting position in the pressing direction, and the transmission is set to the gear position corresponding to the gear position setting position.

For example, in the case of the shift shift device shown in FIGS. 6 (I) (a) to (c) and FIGS. 6 (II) (a) to (c), the shift block b is used to set the shift stage of the first shift line. First and third shift blocks b ₁ and b ₃ to be set, and a second shift block b ₂ to set the gear position of the second shift line. The first to third shift blocks b ₁ , b ₂ , b ₃ are all the same shape and the same size as shown in FIG. These first to third shift blocks b ₁ , b ₂ , b ₃ are independently arranged so as to be linearly movable in the left-right direction in the figure. In this case, the first to third shift blocks b ₁ , b ₂ , b _{3 of} the first and second shift lines are controlled by one shift lever d. Further, when the shift lever d is positioned in the shift-side recess f of the shift block b of one of the first and second shift lines, the neutral return lever e is shifted by another shift block b of the same shift line. It is made to be located in the side recessed part f.

As shown in FIG. 6 (I) (a) and FIG. 6 (II) (a), the first gear of the first shift line is currently
The shift block b ₁ is moved to the 1st setting position, and a first clutch (not shown) is connected, so that the gear position of the transmission is set to 1st. Further, the shift lever d is located in the shift side recess f ₂ of the second shift block b ₂ of the second shift line. Then, the shift lever d comes into contact with the first shift-side pressed portion h ₂ of the shift-side recess f ₂ of the second shift block b ₂ and this first
By pressing the shift-side pressed portion h ₂ , the second shift block b ₂ is moved to the 2nd shift position setting position and the transmission gear is set to 2nd. At this time, since the second clutch (not shown) is disengaged, the gear position of the transmission is not set to 2nd. Further, the third shift block b ₃ is in the neutral (NE) position because the first shift block b ₁ of the same first shift line has moved to the 1st setting position.

From this state, when the traveling speed of the vehicle increases and the condition for setting the transmission gear stage to 2nd is satisfied, the first clutch is disconnected and the second clutch is connected. Therefore, the gear position of the transmission is set to 2nd. From the state where the transmission gear stage is set to 2nd, an operation is performed in which the gear stage is prepared for setting to the next 3rd. At this time, any one of the first to third shift blocks b ₁ , b ₂ , b ₃ in the first and second shift lines is controlled by one shift lever d, so that the shift lever d is moved to the third shift block. b it is necessary to enter the _third shift side recess f _3. However, since the second shift block b ₂ is in the 2nd setting position and the third shift block b ₃ is in the NE position, the shift lever d is moved to the third shift block b ₃ side in the axial direction when the shift lever d is moved to the third shift block b ₃ side. 3 interfere with the shift block b ₃ can not enter the third shift block b ₃ of the shift-side recess f _3. Therefore, it is necessary to move the shift lever d to the NE position in a state where the shift lever d is positioned in the shift-side recess f ₂ of the second shift block b ₂ .

At this time, if the predetermined gap is not provided between the shift lever d and the second shift side pressed portion i _{2 of} the second shift block b ₂ , when the shift lever d moves toward the NE position, The second shift block b ₂ also moves toward the NE position. For this reason, the 2nd shift stage of the set transmission is released. Therefore, a predetermined gap is provided between the shift lever d and the second shift side pressed portion i _{2 of} the second shift block b ₂ . The same applies to the first and third shift blocks b ₁ and b ₃ .

When the shift lever d is in the NE position, FIGS. 6 (I) (b) and 6 (II) (b
), The shifter a moves downward in the axial direction indicated by an arrow in FIGS. 6 (I) and 6 (b). As a result, the shift lever d enters the shift side recess f ₃ of the third shift block b ₃ . At this time, the neutral return lever e is also in the NE position, and the neutral return lever e enters the neutral return side recess g ₁ of the first shift block b ₁ . Next, the shifter a is rotated clockwise in FIGS. 6 (II) and 6 (b) about the rotation axis c. Then, both the shift lever d and the neutral return lever e rotate together in the same direction indicated by the arrow.

Then, first, the neutral return lever e is in contact with the neutral return side recesses g second neutral return-side pressed part k ₁ of ₁ of the first shift block b _1, to the first shift block b ₁ towards the neutral NE position Moving. 6 (II) (a) to (c)
), J ₁ is a first neutral return side pressed portion of the neutral return side recess g ₁ of the first shift block b ₁ . Next, the shift lever d is moved to the third shift block b ₃
A shift side to the first shift-side pressed part h ₃ of the recess f ₃ abuts the third shift block b ₃ 3
It moves toward the rd setting position (leftward in FIGS. 6 (I) and 6 (b) and FIGS. 6 (II) and 6 (b)). Thus, the shifter a moves the third shift block b ₃ toward the 3rd set position while returning the first shift block b ₁ to the neutral NE position.

As shown in FIGS. 6 (I), 6 (c) and 6 (II) (c), when the third shift block b ₃ is in the 3rd set position and the first shift block b ₁ is in the neutral NE position, the shifter a Is stopped, and the gear position is set to 3rd of the first shift line. In FIGS. 6 (II), 6 (b) and 6 (c), i ₃ is a second shift side pressed portion of the third shift block b ₃ .

From the above, when the shift block b, the shift lever d, and the neutral return lever e are in the NE position as shown in FIG. 5, the shift lever d and the first and second shift side pressed portions h, i A predetermined gap α ₁ is provided between them, and a predetermined gap α ₂ is provided between the neutral return lever e and the first and second neutral return side pressed parts j, k.

JP-T-2004-518918. Japanese Patent Application Laid-Open No. 2007-120683.

However, when the above-described predetermined gaps α ₁ and α ₂ are provided, the shift lever d has to move greatly before moving the shift block b, and there is a problem that a large movement loss of the shift lever d occurs. .

  In addition, due to such a movement loss of the shift lever b, it is necessary to increase the rotation amount of the shifter a. For this purpose, there is a problem that the power transmission mechanism for transmitting the power of the motor to the shifter a is enlarged. is there. In addition, an increase in the size of the power transmission mechanism causes an increase in the size of the transmission shift device.

It is an object of the present invention to provide a transmission shift device that can perform the transmission and a transmission including the same.

The second shift line side second pressed portion pressed by the second shift line side first pressed portion and the second shift line side second pressed portion pressed by the second shift line side first pressing portion. Part.

  Furthermore, in the shift shift device of the present invention, the first shift line side first pressed portion and the first shift line side second pressed portion are formed by a groove provided in the first shift line side shift member. The first shift line side first pressing portion and the first shift line side second pressing portion are formed by a member that is detachably fitted to the concave groove.

  Furthermore, in the shift shift device of the present invention, the first shift line side first pressing portion and the first shift line side second pressing portion are formed by concave grooves provided in the first shift line side shift member. The first shift line side first pressed portion and the first shift line side second pressed portion are formed by members that are detachably fitted into the concave grooves.

  Furthermore, the shift shift device of the present invention includes a power transmission mechanism for transmitting the power of the drive means to the first shift line side shift operating member and the second shift line side shift operating member, the power transmission mechanism and the first The power transmission mechanism is disposed between the shift line side shift operating member and the second shift line side shift operating member, and the power transmission mechanism is connected to the first shift line side shift operating member and the second shift line side shift operating member. And a clutch mechanism that is connected or disconnected.

Furthermore, in the shift shift device of the present invention, the clutch mechanism includes a first connection position where the power transmission mechanism is connected to the first shift line side shift operating member, and the power transmission mechanism is shifted to the second shift line side. A second connection position for connecting to the operating member and a neutral position for disconnecting the power transmission mechanism from either the first shift line side shift operating member or the second shift line side shift operating member are set. It is characterized by.
Furthermore, the shift shift device of the present invention is characterized in that the power transmission mechanism has a rack-pinion mechanism.

  Furthermore, in the shift shift device according to the present invention, the shift stage on the first shift line side is at least an odd-numbered shift stage, and the shift stage on the second shift line side is at least an even-numbered shift line. It is characterized by that.

  Further, in the shift shift device of the present invention, the first shift line side shift member group in which the first shift line side shift members are collectively disposed and the second shift line side shift member are collectively disposed. And the second shift line side shift member group disposed adjacent to the first shift line side shift member group.

  In the transmission of the present invention, the first shift line in which the first predetermined number of shift stages is set and the second predetermined number of shift stages different from the shift stage set in the first shift line are set. A second shift line, a first shift line side shift fork set to the corresponding shift stage, and a first shift line side fork set on the first shift line side; Shifts that are provided corresponding to the respective shift stages and that control the operation of the second shift line side shift forks set to the corresponding shift stages, the first shift line side shift forks, and the second shift line side shift forks.

And a second shift line side shift operating member that operates a second shift line side shift member that sets the first gear. Further, the first and second shift line side shift operating members are operated independently. Thus, the second shift line is operated without operating the first shift line side shift operating member in order to prepare for setting the shift stage of the second shift line in a state where the shift stage is set in the first shift line. The side shift operating member can be operated. Conversely, in the state where the gear position is set in the second shift line, in order to prepare for setting the gear position of the first shift line, the first gear shift is not performed without operating the second shift line side shift operating member. The line side shift operating member can be operated. Accordingly, both the movement losses of the first and second shift line side shift operating members can be almost eliminated.

  Further, since each movement loss of the first and second shift line side shift operating members can be almost eliminated, each movement amount of the first and second shift line side shift operating members can be reduced. As a result, it is possible to reduce the size of the power transmission mechanism. Therefore, it is possible to make the shift shift device more compact and compact. In particular, the structure of the power transmission mechanism can be simplified by using a rack-pinion mechanism as the power transmission mechanism.

  Further, since the movement loss of the first and second shift line side shift operating members is almost eliminated, the driving forces of the first and second shift line side shift operating members are more effectively applied to the first and second shift lines, respectively. It can be transmitted to the line side shift member. Thereby, it becomes possible to improve the transmission efficiency of the shift driving force to the first and second shift line side shift members. As a result, it is possible to use a driving means with a smaller output as the driving means for rotationally driving the first and second shift line side shift operating members.

  Further, as the shift operating member, two first and second shift line side shift operating members are employed, and these first and second shift line side shift operating members can be controlled independently. The movement control of the first and second shift line side shift members can be simplified. Thereby, the shifting operation can be easily performed.

  In particular, the first shift line side shift member is collectively arranged in the first shift line side shift member group, and the second shift line side shift member is collectively arranged in the second shift line side shift member group. The first shift line side shift member group and the second shift line side shift member group are disposed adjacent to each other. As a result, the shift shift device can be made more compact and compact, and the movement control of the plurality of shift members can be further simplified.

  On the other hand, according to the transmission of the present invention, any one of the first and second shift line side shift actuating members causes the shift stage to be shifted by any one shift member corresponding to the first and second shift line side shift members. Is set, the other shift stages of the same shift line are not set by the other shift members of the same shift line as the set shift stage. Therefore, it is possible to reliably prevent two gear positions on the same shift line from being set simultaneously. Further, the power transmission mechanism is selectively connected to any one of the first and second shift line side shift operating members by a clutch. Thereby, even if two first and second shift line side shift operating members are employed in the transmission, it is possible to avoid the trouble that two different first and second shift line side shift operating members are simultaneously performed. It is possible with a simple structure.

There is almost no gap in the circumferential direction of the circle centered on the rotation center 43a ₁ of the side shifter 43.

Similarly, the third and fourth shift blocks 47 and 48 have third and fourth concave grooves 47a and 48a, respectively. Both side walls in the moving direction of the third concave groove 47a are the fifth and sixth pressed parts 47b and 47c, respectively. Further, both side walls in the moving direction of the fourth concave groove 48a are respectively set as seventh and eighth pressed portions 48b and 48c. Similarly, the width w ₄ between the fifth and sixth pressed parts 47b and 47c and the seventh and eighth pressed parts 48b and 48c.
The width w ₄ between them is set to be slightly larger than the width w _{3 in} the same direction of the second shift line side first and second pressing portions 44b, 44c of the second shift line side shifter 44. Therefore, as shown in FIG. 4C, when the second shift lever 44d is in the NE position and the third shift block 47 is in the NE position, the second shift line side first and second pressing portions 44b, 44c Is the third
In a state of being fitted in the third concave groove 47a of the shift block 47, the second shift line side first and second pressing portions 44b, 44c and the fifth and sixth pressed portions 47b, 47c There is almost no gap in the circumferential direction of the circle centered on the rotation center 44 a ₁ of the shift line side shifter 44. Similarly, as shown in FIG. 4D, the second shift line side first and second pressing portions 44b,

In this example, the first to fourth concave grooves 45a, 46a, 47a, 48
a is formed in the same size as each other, and the first shift line side first and second pressing portions 43b and 43c and the second shift line side first and second pressing portions 44b and 44c are also set in the same size. (Ie, w ₁ = w ₃ ; w ₂ = w ₄ ).

  The first shift block 45 is arranged between the NE position shown in FIG. 4A, the 1st setting position set above the NE position in the figure, and the 3rd setting position set below the NE position in the figure.

Further, the fourth shift block 48 includes an NE position shown in FIG. 4D, a 6th setting position set upward in the figure from the NE position, and a Rev setting position set downward in the figure from the NE position. As shown by a double-pointed arrow, linear movement is possible.

The first shift line side first and second pressing portions 43b, 43c of the first shift lever 43d are inserted into the first and second concave grooves 45a, 46a of the first and second shift blocks 45, 46, respectively.
Are fitted in the third and fourth concave grooves 47a and 48a of the third and fourth shift blocks 47 and 48, and the second shift line side first and second of the second shift lever 44d.
The pressing portions 44b and 44c are selectively fitted. Accordingly, the first shift line side shifter 43 controls the movement of the first and second shift blocks 45 and 46, thereby allowing the first shift line side shifter 43 to move.
The shift setting for the odd number of forward stages of the shift line A is performed. Further, the second shift line side shifter 44 controls the movement of the third and fourth shift blocks 47 and 48, so that the shift setting of the even-numbered and reverse stages of the second shift line B is performed.

As shown in FIG. 3, when the first shift line side shifter 43 is in the upper limit position, the first shift line side first and second pressing portions 43 b, 43 c are the first concave grooves 45 a of the first shift block 45. And when the second shift line side shifter 44 is in the lower limit position, the second shift line side first and second pressing portions 44 b and 44 c are connected to the third shift block 47.
It fits into the groove 47a. Further, when the first shift line side shifter 43 is moved down from the upper limit position to the position indicated by the two-dot chain line, the first shift line side first and second pressing portions 43b, 43c are the second shift block 46 second. It fits in the groove 46a.

It fits in the groove 48a.
Thus, the first shift line side first and second pressing portions 43b, 43c of the first shift line side shifter 43 are connected to the first and second concave grooves 45a, 4 of the first and second shift blocks 45, 46, respectively.
It selectively fits into any one of 6a. Further, the second shift line side first and second pressing portions 44b, 44c of the second shift line side shifter 44 are either of the third and fourth concave grooves 47a, 48a of the third and fourth shift blocks 47, 48. One of them is selectively fitted.

As shown in FIG. 2, the power transmission mechanism 49 includes a rack-pinion mechanism including a rack 55 having a predetermined number of rack teeth 55a and a fan-shaped pinion 56 having external teeth 56a meshing with the rack teeth 55a. Has been. In this case, each rack tooth 55a and each external tooth 56a are all extended in the same direction as the moving direction of the first and second shift line side shifters 43, 44 in the axial direction (vertical direction in FIG. 2). The rack 55 is provided on the apparatus main body 52 so as to be linearly movable in the direction indicated by the double arrow, that is, in the same direction as the tangential direction of the rotation circle of the pinion 56. The linear movement of the rack 55 is performed via a known motion conversion mechanism that converts the rotational motion of the motor into linear motion by the power of the motor (not shown).

The pinion 56 is provided on the apparatus main body 52 so as to be linearly movable and rotatable in the direction indicated by the double arrows, that is, in the same direction as the linear movement direction of the first and second shift line side shifters 43 and 44. Then, the pinion 56 is rotated by the linear movement of the rack 55. Further, the linear movement of the pinion 56 is performed via a known motion conversion mechanism that converts the rotational motion of the motor into a linear motion by the power of another motor (not shown).

  As shown in FIG. 2, the clutch mechanism 50 includes a drive side portion 57 provided at an end portion (fan-like main portion) opposite to the external teeth 56 a of the pinion 56, and a first rotation shaft of the first shift line side shifter 43. 43a, the first driven side 58 provided at the end opposite to the first shift lever 43d (the upper end in FIG. 2), and the second shift lever of the second rotating shaft 44a of the second shift line side shifter 44. It has the 2nd driven side part 59 provided in the edge part (upper end part in FIG. 2) on the opposite side to 44d.

The driving side portion 57 has a predetermined number of spline grooves 57b formed on the inner peripheral surface of the circular hole 57a. All of the spline grooves 57b are the first and second shift line side shifters 43, 4
4 extends in the same direction as the linear movement direction. The first driven side portion 58 has a shaft portion 58a that can be slidably passed through the circular hole 57a of the drive side portion 57, and is formed on the outer peripheral surface of the shaft portion 58a and is slidable in each spline groove 57b. A first spline tooth 58b that can be fitted and an annular first flange 58c that cannot pass through the circular hole 57a of the drive side portion 57 are provided. Further, the second driven side portion 59 is formed on a shaft portion 59a that can pass through the circular hole 57a of the drive side portion 57, and is formed on the outer peripheral surface of the shaft portion 59a, and can be slidably fitted in each spline groove 57b. The second spline teeth 59b and the circular second flange 59c that cannot pass through the circular hole 57a of the driving side portion 57 are provided.

In addition, a predetermined gap is formed in the axial direction between the upper end of the first spline teeth 58b and the lower end of the second spline teeth 59b. When the driving side portion 57 is located in this gap, each spline groove 57b does not fit into any of the first and second spline teeth 58b, 59b,
The driving side portion 57 is in a neutral position that is not connected to any of the first and second driven side portions 58 and 59. In this case, the predetermined gap described above is minimized when the first shift line side shifter 43 is at the upper limit position and the second shift line side shifter 44 is at the lower limit position. The neutral position where the part 57 is not connected to any of the first and second driven side parts 58 and 59 is secured. Further, the first and second spline teeth 58b, 59b are aligned in the axial direction regardless of whether the first to fourth shift blocks 45, 46, 47, 48 are in the NE position or the gear position setting position, respectively. It is arranged.

In a state where the spline groove 57b is fitted to the first spline teeth 58b, the driving side portion 57 and the first driven side portion 58 are connected in the rotation direction. That is, the driving side portion 57 and the first driven side portion 58 constitute the third clutch 50a. Further, in a state where the spline groove 57b is fitted to the second spline teeth 59b, the driving side portion 57 and the second driven side portion 59 are connected in the rotational direction. That is, the fourth clutch 50 b is configured by the driving side portion 57 and the second driven side portion 59. By these third and fourth clutches 50a, 50b, the clutch mechanism 5
0 is configured.

Next, the operation of the shift shift device 42 will be described.
During normal operation (when no shift is set), the first and second shift line side shifters 43 and 44 and the pinion 56 are all in the positions shown in FIGS. That is, as described above, the first shift line side shifter 43 is in the upper limit position, and the second shift line side shifter 44 is in the lower limit position. The first and second shift levers 43d, 44d and the first to fourth shift blocks 45, 46, 47, 48 are all set at the NE position. Therefore, the first
The transmission line side first and second pressing portions 43 b and 43 c are recessed grooves 45 of the first shift block 45.
The second shift line side first and second pressing portions 44 b and 44 c are located in the concave groove 47 a of the third shift block 47 while being located within a. Further, the driving side portion 57 of the clutch mechanism 50 is located at the neutral position, and neither of the first and second spline teeth 58b and 59 is fitted in the spline groove 57b. That is, the third and fourth clutches 50a,
All 50b are cut.

In order to set the transmission 1 to the forward 1st from this state of the transmission shift device 42, the pinion 56 is moved downward by the power of the motor that moves the pinion 56 up and down, and the first spline teeth 58b are fitted into the spline grooves 57b. Match. That is, the third clutch 50a is connected. At this time, even if the pinion 56 moves downward, the meshing between the rack teeth 55a and the external teeth 56a is maintained. Then, the rack 55 is moved by the power of the motor to rotate the pinion 56 counterclockwise as shown in FIGS. 2 and 4A. Then, the first shift lever 43d of the first shift line side shifter 43 also rotates in the same direction via the third clutch 50a, so that the first shift line side first pressing portion 43b is connected to the first shift block 45 in the first cover. In FIG. 4A, the pressing portion 45b is pressed upward, that is, toward the first setting position. As a result, the first shift block 45 moves in the same direction to the first setting position, and the first clutch 3 is connected in the same manner as the transmission described in Patent Document 1 or 2 described above. The transmission 1 is set to 1st. When the first shift line side first pressing part 43b starts pressing the first shift block 45, in the circumferential direction of a circle about the rotational center 43a ₁ of the first transmission line side shifter 43 as previously described first Since there is almost no gap between the transmission line side first pressing portion 43b and the first pressed portion 45b, the first shift lever 43d is substantially the same as the rotation of the first shift lever 43d without causing a large movement loss. At the same time, the first shift line side first pressing portion 43b of the first shift lever 43d starts pressing the first shift block 45.

When preparing to set the 2nd shift stage with the transmission 1 set to 1st, the drive side portion 57 is moved up to the initial neutral position while the first shift block 45 is at the 1st set position. The 3 clutch 50a is disconnected. Thereafter, the pinion 56 is rotated in the clockwise direction opposite to the above, and when the pinion 56 reaches the initial NE position, the rotation of the pinion 56 is stopped. At this time, the control device controls the drive of the motor so that the pinion 56 stops at the NE position, so that the pinion 56 stops at the NE position with high accuracy. On the other hand, since the third clutch 50a is disengaged, the first shift lever 43d is held at the position where the first shift block 45 is set to the 1st setting position, and the first shift block 45 is held at the 1st setting position. . Therefore, the gear position of the transmission 1 is set and held at 1st.

Next, when the pinion 56 is moved upward, the spline groove 57b is fitted to the second spline teeth 59b and the fourth clutch 50b is connected. At this time, even if the pinion 56 moves up, the meshing between the rack teeth 55a and the external teeth 56a is maintained. Then, the rack 55 is moved by the power of the motor to rotate the pinion 56 counterclockwise as shown in FIGS. 2 and 4A. Then, the second shift lever 44 d of the second shift line side shifter 44 also rotates in the same direction via the fourth clutch 50 b, so that the second shift line side first pressing portion 44 b is connected to the fifth shift block 47. In FIG. 4C, the pressing portion 47b is pressed upward, that is, toward the 2nd set position. As a result, the third shift block 47 moves in the same direction to the 2nd setting position, and the forward 2nd is prepared for setting. When the second shift line side first pressing part 44b starts pressing the third shift block 47, in the circumferential direction of a circle about the rotational center 44a ₁ of the second transmission line side shifter 44 as previously described second Since there is almost no gap between the pressing portion 44b and the fifth pressed portion 47b, the second shift lever 44d does not cause a large movement loss and almost simultaneously with the rotation of the second shift lever 44d. The second shift line side first pressing portion 44b of the lever 44d starts pressing the third shift block 47.

  When the traveling speed of the vehicle increases and the 2nd condition is satisfied, the first clutch 3 is disconnected and the second clutch 4 is connected. Thereby, the gear position of the transmission 1 is set to 2nd forward.

  When preparing to set the forward 3rd speed with the transmission 1 set to the forward 2nd, the drive side 57 is moved down to the initial neutral position with the third shift block 47 in the 2nd setting position. The As a result, the fourth clutch 50b is disconnected. Further, when the drive side portion 57 is moved downward, the third clutch 50a is connected in the same manner as described above. Next, when the pinion 56 is rotated clockwise, the first shift lever 43d is also rotated in the same direction via the third clutch 50a. Then, the first shift line side second pressing portion 43c presses the second pressed portion 45c of the first shift block 45 downward in FIG. 4A, that is, toward the 2nd set position. At this time, since there is almost no gap between the first shift line side second pressing portion 43c and the second pressed portion 45c, the first shift block by the first shift line side second pressing portion 43c is the same as described above. The pressing of 45 is started almost simultaneously with the start of rotation of the first shift lever 43d. As a result, the first shift block 45 moves toward the initial NE position and the 3rd set position. Further, the third shift block 47 remains held at the 2nd setting position, and the gear position of the transmission 1 remains set and held at 2nd.

  When the first shift block 45 reaches the 3rd setting position, the rotation of the pinion 56 is stopped. In this way, the 3rd gear position is prepared for setting. When the 3rd condition is satisfied, the second clutch 4 is disconnected and the first clutch 3 is connected. Thereby, the gear position of the transmission 1 is set to 3rd.

When preparing to set the 4th shift stage with the transmission 1 set to 3rd, the drive side portion 57 is moved up to the initial neutral position while the first shift block 45 is at the 3rd set position. As a result, the third clutch 50a is disconnected. Further, when the drive side portion 57 is moved upward, the fourth clutch 50b is connected in the same manner as described above. Next, when the pinion 56 is rotated clockwise, the second shift lever 44d is also rotated in the same direction via the fourth clutch 50b. Then, the second shift line side second pressing portion 44c presses the sixth pressed portion 47c of the third shift block 47 downward in FIG. 4C, that is, toward the 4th set position. At this time, since there is almost no gap between the second shift line side second pressing portion 44c and the sixth pressed portion 47c, the third shift block by the second shift line side second pressing portion 44c in the same manner as described above. The pressing of 47 is started almost simultaneously with the start of rotation of the second shift lever 44d. As a result, the third shift block 47 moves toward the initial NE position and the 4th set position. In addition, the first shift block 45 remains held at the 3rd setting position, and the gear position of the transmission 1 remains set and held at 3rd.

  When the third shift block 47 reaches the 4th setting position, the rotation of the pinion 56 is stopped. In this way, the 4th shift stage is prepared for setting. When the forward 4th condition is satisfied, the first clutch 3 is disconnected and the second clutch 4 is connected. Thereby, the gear position of the transmission 1 is set to 4th.

  When preparing to set the forward 5th gear position with the transmission 1 set to 4th, the drive side portion 57 is moved down to the initial neutral position while the third shift block 47 is at the 4th setting position. . As a result, the fourth clutch 50b is disconnected. Further, when the drive side portion 57 is moved downward, the third clutch 50a is connected in the same manner as described above. Next, when the pinion 56 is rotated counterclockwise, the first shift lever 43d is also rotated in the same direction via the third clutch 50a. Then, the first shift line side first pressing portion 43b presses the first pressed portion 45b of the first shift block 45 upward in FIG. 4A, that is, toward the NE position. At this time, in the same manner as described above, the pressing of the first shift block 45 by the first shift line side first pressing portion 43b is started almost simultaneously with the start of the rotation of the first shift lever 43d. As a result, the first shift block 45 moves toward the initial NE position. When the first shift block 45 is in the NE position, the rotation of the pinion 56 is stopped and the movement of the first shift block 45 is stopped. At this time, the third shift block 47 remains held at the 4th set position, and the gear position of the transmission 1 remains set and held at 4th.

When the first shift block 45 stops at the NE position, the first groove 45a of the first shift block 45 and the second groove 45a of the second shift block 46 overlap in the linear movement direction of the first shift line side shifter 43. . Next, when the drive side portion 57 is further moved downward, the drive side portion 57 engages with the first flange 58c and the first shift line side shifter 43 is pressed downward. As a result, the compression spring 54 contracts and the first shift line side shifter 43 moves downward along with the downward movement of the drive side portion 57. The first shift line side first and second pressing portions 43b, 43c are the first
When the first concave groove 45a of the shift block 45 is escaped and fitted into the second concave groove 46a of the second shift block 46, the downward movement of the pinion 56 is stopped. Also at this time, the meshing between the rack teeth 55a and the pinion teeth 56a is maintained. In this state, when the pinion 56 is rotated counterclockwise in the same manner as described above, the second shift block 46 is moved to the 5th set position. Also at this time, since the aforementioned gap does not exist between the first shift line side first pressing portion 43b and the third pressed portion 46b of the second concave groove 46a, the first shift lever 43d causes a movement loss. The first shift line side first pressing portion 43b presses the second shift block 46 almost simultaneously with the rotation of the first shift lever 43d.

  When the second shift block 46 reaches the 5th set position, the rotation of the pinion 56 is stopped. Thus, the 5th shift stage is prepared for setting. When the 5th condition is satisfied, the second clutch 4 is disconnected and the first clutch 3 is connected. Thereby, the gear position of the transmission 1 is set to 5th.

Thereafter, the shift control is sequentially performed at the high speed in the same manner. In that case, the second shift line side first and second pressing portions 44b, 44c of the second shift line side shifter 44 are caused to escape from the third concave groove 47a of the third shift block 47, so that the fourth shift block 48 has a fourth. In order to fit the groove 48a, the drive side portion 57 is moved upward to connect the fourth clutch 50b, and then the drive side portion 57 is further moved upward to engage with the second flange 59c and the second flange 59c is engaged. The shift line side shifter 44 is pressed upward. As a result, the compression spring 54 contracts and the second shift line side shifter 44 moves up together with the upward movement of the drive side portion 57. The second shift line side first and second pressing portions 44 b and 44 c escape from the third groove 47 a of the third shift block 47 and fit into the fourth groove 48 a of the fourth shift block 48.

The shift control from the high speed stage to the low speed stage and the shift control from the NE position to the reverse stage are similarly performed.
Further, other configurations and other operational effects of the shift shift device and the transmission of this example are the same as those of the conventional shift shift device and the transmission described in Patent Document 1 or 2 described above, for example.

According to the shift shift device 42 of the present invention configured as described above, the first and second shift blocks 45 and 46 that set the shift stages 1st, 3rd, 5th, and 7th of the first shift line A are operated. A first shift line side shifter 43; a second shift line side shifter 44 that operates third and fourth shift blocks 47, 48 that respectively set the shift speeds 2nd, 4th, 6th, and Rev of the second shift line B; have. Further, the first and second shift line side shifters 43 and 44 are operated independently of each other. Accordingly, in order to prepare for setting one of 2nd, 4th, 6th and Rev of the second shift line B in a state where one of 1st, 3rd, 5th and 7th is set in the first shift line A Only the second shift line side shifter 44 can be operated without operating the first shift line side shifter 43. Conversely, in the state where one of the aforementioned shift stages is set in the second shift line B, the second shift line side shifter is used to prepare for setting one of the aforementioned shift stages of the first shift line A. The first shift line side shifter 43 can be operated without operating 44. Accordingly, both the movement losses of the first and second shift line side shifters 43 and 44 can be almost eliminated.

Further, since it is possible to almost eliminate the respective movement losses of the first and second shift line side shifters 43 and 44, the respective movement amounts of the first and second shift line side shifters 43 and 44 can be reduced. it can. As a result, the power transmission mechanism 49 can be reduced in size. Therefore, the shift shift device 42 can be made smaller and more compact. In particular, the structure of the power transmission mechanism 42 can be simplified by using the rack-pinion mechanisms 55 and 56 as the power transmission mechanism 49.

Further, since the movement loss of the first and second shift line side shifters 43 and 44 is almost eliminated, the driving forces of the first and second shift line side shifters 43 and 44 are more effectively applied to the first to second shifters. 4 shift blocks 45, 46, 47 and 48 can be transmitted.
As a result, the transmission efficiency of the shift driving force to the first and second shift line side shifters 43 and 44 can be improved. As a result, it is possible to use a motor with a smaller output as a driving means for rotationally driving the first and second shift line side shifters 43 and 44.

Further, as the shifters, two first and second shift line side shifters 43 and 44 are adopted, and these first and second shift line side shifters 43 and 44 can be independently controlled. The movement control of the first to fourth shift blocks 45, 46, 47, 48 can be simplified. Thereby, the shifting operation can be easily performed. Moreover, the first and second rotary shafts 43a, 4 of the first and second shift line side shifters 43, 44 are provided.
Since the 4a is arranged concentrically, the shift shift device 42 can be made even smaller and more compact.

In particular, the first and second shift blocks 45, 46 are arranged together in the first shift line side shift block group, and the third and fourth shift blocks 47, 48 are grouped in the second shift line side shift block group. Further, the first shift line side shift block group and the second shift line side shift block group are disposed adjacent to each other. As a result, the shift shift device 42 can be made smaller and more compact, and the movement control of the first to fourth shift blocks can be further simplified.

On the other hand, according to the transmission 1 of this example, when one of the first and second shift line side shifters 43 and 44 is used to set the gear position in any one of the plurality of shift blocks, It is not set to another shift stage of the same shift line by another shift block of the same shift line as the set shift stage. Therefore, it is possible to reliably prevent two gear positions on the same shift line from being set simultaneously. Further, the power transmission mechanism 49 is selectively connected to any one of the first and second shift line side shifters 43 and 44 by the clutch mechanism 50. As a result, even if the two first and second shift line side shifters 43 and 44 are employed, it is easy to avoid the trouble that two different first and second shift line side shifters 43 and 44 are simultaneously performed. It is possible with certainty.

In addition, this invention is not limited to the above-mentioned example, A various design change is possible. For example, in the above-described example, the concave grooves 45a, 46a, 47a, 48a are provided in the first to fourth shift blocks, respectively, and the first and second shift levers 43, 44 are provided in the concave grooves 4
5a, 46a, 47a, and 48a are fitted, but the first and second shift levers 43d and 44d are provided with concave grooves, and the first to fourth shift blocks are fitted into the concave grooves, respectively. A convex part can also be provided.

In the above-described example, the first and second shift line side shifters 43 and 44 are rotatable, but they can be moved linearly. Further, instead of a motor for moving the rack 55 or a motor for moving the pinion 56 up and down, other drive means such as an electromagnetic solenoid can be used. In short, various design changes can be made within the scope of the matters described in the claims.
