Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a shift lever device for operating a transmission of an automobile, for example.

(Prior Art) For example, gear type transmissions in automobiles are generally operated mechanically by operating a shift lever, either directly or via a link, but in recent years, the operability of the shift lever has improved. In order to improve this, a shift lever device is provided with a switch that operates in response to the operation of the shift lever, and the operation of this switch indirectly operates a gear type transmission via a hydraulic device. An example of this will be explained with reference to FIGS. 5 to 8. Reference numeral 1 denotes a substantially rectangular cylindrical support that is erected and fixed on the floor of the driver's seat of a vehicle, and 2 is a horizontal shift shaft that is provided at the lower part of the support 1 so that it can rotate and move back and forth in the left and right directions. is always in the sixth position due to the compression coil springs 3, 3.
It is in the neutral state shown in the figure. A shift lever 4 is connected to the center of the horizontal shift shaft 2 by a shaft 5, and has a shift knob 6 at the top. Then, by operating the shift knob 6 in the longitudinal direction (in the direction of arrow A and the direction opposite to arrow A in FIG. 5), the shift lever 4 is tilted in the longitudinal direction, so that the horizontal shift shaft 2
is starting to rotate. On the other hand, reference numeral 7 denotes a front and rear shift shaft whose both ends are supported movably in the front and rear direction in fan-shaped holes 8 provided on both sides of the support body 1, and the intermediate part of the shift lever 4 is connected to this shaft through a shaft 9. It is rotatably supported through an elongated hole (not shown). When the shift lever 4 is operated in the lateral direction (arrow B direction and counter-arrow B direction in FIG. 5), the shift lever 4 rotates about the shaft 9, and the lateral shift shaft 2 moves in the lateral direction. .

The horizontal shift shaft 2 and the support body 1 are respectively provided with a movable part 10 for guiding the shift lever 4 in the longitudinal direction and the lateral direction in the operating locus, and a regulating part 13 that abuts on the movable part 10. This will be explained below. Reference numeral 10 denotes a thick plate-shaped movable portion fixed to one end of the horizontal shift shaft 2, and a cross-shaped guide groove consisting of a vertical groove 11 and a horizontal groove 12 perpendicular to the vertical groove 11 is provided on the circumferential surface portion 10a of the movable portion 10. is formed. On the other hand, reference numeral 13 is a regulating portion provided on the support body 1 facing the circumferential surface portion 10a of the movable portion 10. This regulating part 13 has a cylindrical protrusion 13a that protrudes into the guide groove of the movable part 10 and comes into contact with the groove.When the shift lever 4 is in the neutral position, the protrusion 13a is located at the center of the guide groove (vertical). It is located at the intersection of the groove 11 and the lateral groove 12). When the shift lever 4 is operated from the neutral position in the longitudinal direction (in the direction of the 3rd and 4th gear positions), the protrusion 13a moves relatively within the vertical groove 11, causing the shift lever 4 to move in the lateral direction. While being prohibited from moving, it is guided in the longitudinal direction and operated to the third and fourth gear positions. Also, when the shift lever 4 is operated laterally from the neutral position, the movable part 10
As the protrusion 13a moves laterally, the protrusion 13a moves into the lateral groove 1.
2, and finally escapes laterally from the lateral groove 12 and is located on the side surface of the movable part 10.
Then, when the shift lever 4 is operated in the front-rear direction (1st speed, 2nd speed, D range, R position direction) from this state, the protrusion 13a moves relatively onto the side surface of the movable part 10 as the movable part 10 rotates. By moving the shift lever 4 while making contact with the shift lever 4, the shift lever 4 can be operated to the 1st speed, 2nd speed, D range, and R shift positions. When the shift lever 4 is operated to a respective shift position, the shift position is detected by a switch (not shown), and based on this, the gear type transmission is shifted by a hydraulic system.

(Problem to be solved by the invention) However, in the case of the above-mentioned one, when the shift lever 4 is operated in the front-rear direction, the protrusion 13 always
a comes into contact with the longitudinal groove 11 of the rotating movable part 10 or the side surface of the movable part 10, and as a result, each time the shift lever 4 is operated in the front-rear direction, the protrusion 13a wears out and its durability is degraded. It had some problems. Further, since the vertical grooves 11 and the horizontal grooves 12 provided in the movable part 10 are cross-shaped grooves, there is also a problem that it is difficult to process them.

The present invention was developed in view of the above circumstances, and its purpose is to reduce the wear of the regulating part that comes into contact with the movable part during shift lever operation and guides the shift lever along the operating trajectory. It is an object of the present invention to provide a shift lever device that has improved durability and can simplify the shape of its movable part to improve the manufacturability of the movable member.

[Structure of the invention] (Means for solving the problem) The invention comprises a shift lever rotatably supported around two axes extending in directions orthogonal to each other,
The operating locus of the shift lever is guided along one direction and the other direction extending orthogonally to each other by a movable part that is integrally displaced as the shift lever is operated and a restriction part that the movable part abuts. In the shift lever device, one of the movable part and the regulating part is composed of a pair of protrusions facing each other, and the other is located between the protrusions to control the one-way operation trajectory of the shift lever. It is characterized in that it is formed into a plate shape for guiding the shift lever, and is provided with a notch through which the protrusion passes in order to allow the shift lever to move to the other direction operation locus.

(Operation) According to the above means, when the shift lever is operated in one direction (for example, in the front-back direction) from a state where the movable part is located between the pair of protrusions, the movable part is displaced while coming into contact between the protrusions. By doing so, the shift lever is guided in one direction along the operation locus. Furthermore, when the shift lever is operated in one direction to position the protrusion opposite to the notch, and the shift lever is then operated in the other direction (for example, horizontally), the protrusion passes through the restriction part, causing the shift lever to directional operation is permitted and the shift lever is guided in the other direction in the operation locus. When the shift lever is operated in the front-rear direction with the protrusion completely passing through the restriction part, the movable part moves while coming into contact with one of the protrusions, but does not come into contact with the other protrusion. Therefore,
In the shift lever device of the present invention, since the chance of one of the pair of protrusions coming into contact with the movable part is halved, the friction speed thereof is also halved. Also,
Since the notch of the movable part may be a straight groove, its manufacture is simple.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. However, from Figures 5 to 8
Components that are the same as those in the figures are given the same reference numerals and detailed explanations will be omitted. That is, the shift lever 4 is connected to the horizontal shift shaft 2.
The movable part 14, which will be described later, is guided by a regulating part 16 that abuts on the shaft 5 of the lateral shift shaft 2 and the shaft 9 of the longitudinal shift shaft 7. It can be operated along an operation locus in one direction (one direction), and can also be operated on an operation locus in a lateral direction (the other direction) in a direction perpendicular to the front-rear direction with the shaft 9 as the center of rotation. The movable part 14 and the restriction part 16 that guide the operation of the shift lever 4 in the longitudinal direction and the lateral direction in the operation locus will be described in detail below. A plate-shaped movable part 14 is fixed to one end of the horizontal shift shaft 2, and rotates together with the horizontal shift shaft 2 when the shift lever 4 is operated in the longitudinal direction (one direction). (other direction)
It is adapted to move laterally together with the lateral shift shaft 2 by the operation of . Circumferential surface portion 14a of this movable portion 14
, a straight groove-shaped notch 15 is formed in the movable part 14.
is formed along the direction of lateral movement. on the other hand,
A restricting portion 16 is fixed to the support body 1 so as to face the circumferential surface portion 14a of the movable portion 14. This regulation part 1
6 is a cylindrical protrusion 16b formed by press-fitting, for example, two pins into a cylindrical base 16a to form a pair of opposing cylindrical protrusions;
16c, these protrusions 16b,
The regulating portion 16 is fixed to the support body 1 such that the regulating portions 16c are aligned in the lateral movement direction of the lateral shift shaft 2. When the shift lever 4 is in the neutral position, the protrusions 16b and 16c are in positions sandwiching the circumferential surface 14a of the movable part 14, as shown in FIG. 4, and allow the movable part 14 to rotate. At the same time, as shown in FIG.
The movable portion 14 is located in a position opposite to the movable portion 14, and has a positional relationship that allows the movable portion 14 to move in the lateral direction. On the other hand, the support body 1 is provided with a plurality of switches (not shown), which detect when the shift lever 4 is operated to each gear position and give a signal to the hydraulic system.
Based on this, the hydraulic device changes the speed of the gear type transmission.

Next, the operation of the above configuration will be explained. first,
The shift lever 4 is fully tilted in the direction of arrow C against the compression coil spring 3 from the neutral position shown in FIG. Then, the shift lever 4 tilts about the shaft 9, thereby moving the lateral shift shaft 2 and, in turn, the movable portion 14 in the direction of arrow D. Then, the protrusion 16c moves relative to the movable part 14 in the direction opposite to the arrow D, and when it completely passes through the notch 15, it moves from the one side 14b side of the movable part 14 to the other side 14c side. When the shift lever 4 is tilted forward (in the direction of arrow E) from this state, the protrusion 16c comes into contact with the other side surface 14c as the lateral shift shaft 2 and thus the movable part 14 rotate in the direction of arrow F. while moving relatively. In other words, the movable part 14 rotates in the direction of arrow F while being prohibited from moving in the opposite direction of arrow D, and as a result, the shift lever 4 is guided forward in the operating trajectory and is operated to the first gear shift position. . Then, a switch (not shown) detects that the shift lever 4 is positioned at the first speed, and based on this, the gear type transmission device (not shown) is shifted to the first speed by the hydraulic system. Next, when the shift lever 4 is fully tilted backwards (counter-arrow E direction) from the first gear shift position, the movable part 14 rotates in the counter-arrow F direction, and the protrusion 16c moves in the same way as described above. It moves relatively while contacting the other side surface 14 of the portion 14. As a result, the shift lever 4 is guided backward in the operation trajectory and operated to the second speed shift position, and the gear type transmission is shifted from the first speed to the second speed by the hydraulic system. Next, operate the shift lever 4 forward from the 2nd gear position,
The protrusion 16c of the regulating portion 16 is the notch 1 of the movable portion 14.
The movable part 14 is rotated until it reaches a position opposite to the position shown in FIG. Then, until then, it comes into contact with the other side surface 14c of the movable part 14 and moves in the lateral direction of the movable part 14 (in the direction opposite to arrow D).
The protrusion 16c, which had been prohibited from moving, moves relative to the movable part 14 in the direction of arrow D due to the biasing force of the compression coil spring 3, and passes through the notch 15. In other words, the movable portion 14 is allowed to move in the lateral direction (in the opposite direction of arrow D) and is positioned between the pins 16b and 16c. When the shift lever 4 is operated forward from this state (neutral), the movable part 1
By rotating the circumferential surface portion 14a of the shift lever 4 while being sandwiched between the protrusions 16b and 16c, the shift lever 4
is guided forward in the operation locus and operated to the third speed shift position, and based on this, the gear type transmission is shifted to the third speed. Similarly, rotation and lateral movement of the movable part 14 are permitted or prohibited by the pins 16b and 16c, so that
The shift lever 4 is guided in the longitudinal and lateral directions of its operation locus to shift to 4th gear, D range, and R range.
(reverse), so that the gear type transmission can be shifted in accordance with the respective shift positions of the shift lever 4. Incidentally, when the shift lever 4 is operated to the D range, the gear type transmission is automatically shifted by a hydraulic system according to the vehicle speed of the automobile.

Now, in the case of the above configuration, the movable part 14 that rotates as the shift lever 4 is operated in the front and rear direction,
Since the shift lever 4 is guided in the front-back direction by contacting the protrusions 16b and 16c of the regulating portion 16, respectively, one of the protrusions 16b and 16c comes into contact with the movable portion 14. Opportunities are halved compared to conventional configurations. Therefore, wear of the protrusions 16b and 16c can be halved and durability can be improved. In addition, the movable part 1
4, the shape of the notch 15 that allows the protrusions 16b and 16c to pass through is a linear groove in the circumferential surface 14a of the movable part 14, unlike the conventional structure in which a cross-shaped groove is formed in the movable part. Since the simple process of forming only one piece is sufficient, the movable part 14 can be easily manufactured by, for example, press working.

Further, in this embodiment, the regulating portion 16 has a pair of protrusions 1.
6b and 16c, and the movable part 14 is made into a plate shape, and the cutout part 15 is formed in the movable part 14. However, instead of this, a pair of protrusions are formed in the movable part 14, and the regulating part 16 is made into a plate shape. It is also possible to form a notch in the regulating portion 16.

In addition, the present invention is not limited to what is described above and shown in the drawings, and can be implemented with various modifications without departing from the scope of the invention.

[Effects of the invention] As is clear from the above description, the present invention pairs one of the movable part that is integrally displaced by the operation of the shift lever and the restriction part that this movable part comes into contact with, facing each other. The other is formed into a plate shape that is located between the protrusions and guides the shift lever in one direction, and also allows the shift lever to move to the other direction. Since a notch is provided for the protrusion to pass through, when the shift lever is guided in one direction in its operating trajectory, the chances of the movable part coming into contact with the protrusion are halved, thereby reducing the chance of the movable part coming into contact with the protrusion. Wear is halved and the durability of the protrusion is improved. Further, since the notch of the movable part that allows the passage of the protrusion can be formed into a simple linear shape, it is possible to improve the manufacturability of the movable part, which is an excellent effect.
