Abstract

PURPOSE:To reduce both the setting space and the oscillating space of a shift lever by moving a knob horizontally to the shift lever and turning on and off a switch to the shifted operating position. CONSTITUTION:A knob 2 can be slided right and left against a lever tube 20 fixed to a shift lever 3 and switches 15 and 16 are provided at the lower end part of the knob 2. When the knob 2 is moved right or left, the tube 20 has a contact with the switch 15 or 16 to turn on and off these switches. The knob 2 is moved in the selecting direction and therefore it is regarded that the lever 3 is selected. Furthermore, the lever 3 can oscillate in the front-back direction, i.e., the direction approximately orthogonal to the right-left direction only at the position of a lock groove 13 for a pin 5 of the knob 2. As a result, a shift lever device 1 is controlled by a double-H pattern.

[Conventional technology]

Particularly in heavy vehicles such as large buses and large trunks, when using a manual mechanical transmission type gear shift operation mechanism, a large amount of operating force is required to shift the gear, and slippage occurs, which means smooth gear shifting and saving. From the point of view of fuel efficiency, the number of gears is large (
Recently, measures have been taken to reduce the physical and mental burden on drivers by adopting electronically controlled transmissions, etc., and to improve the stability and safety of automobiles. ing. In this electronically controlled transmission, the driver operates the shift lever with a light operating force to turn on the switch, and a signal from the shift lever activates the hydraulic actuator to perform gear shifting. It is composed of two parts. Conventionally, as a shift lever device used in such an electronically controlled transmission, there is a device as disclosed in, for example, Japanese Utility Model Application No. 58-85527. This selection command operating device will be outlined with reference to FIGS. 10 and 11.

In FIGS. 10 and 11, the guide groove 51 for guiding the shift lever 50 has a shape in which a select l in the left and right direction and three rows of shift grooves in the front and rear direction communicate with each other. are the select position aNt and the select position N1, respectively. N3, and the front and rear ends of the shift grooves in each row correspond to the respective gears. When the shift lever 50 is not operated, it is located at the central select position N2. In this state, the shift lever 50 is held stationary by the click action of the check ball 52 and the hole 53, and its select swing is not performed. ,
It is pressed by the cam plate 54 and is biased back in a direction to maintain this state.

When commanding a gear shift operation, first swing the shift lever 5° to the desired select position along the guide groove 51; Secondary rocking, ie shift nut movement operation. In this case, during the select swing, the shift lever 50 rotates integrally with the front shaft 59 and the rear shaft 6o to which the select operating lever 55 is fixed, and during the shift swing, the shift lever 57 is fixed to the front shaft 59 and the rear shaft 6o. It rotates integrally with the supporting shaft 61.

[Problem that the invention seeks to solve]

However, in the case of the shift lever 50 disclosed in the above-mentioned Japanese Utility Model Publication No. 58-85527, the shift lever 50 is structured to swing in the select direction and the shift direction around the intermediate portion thereof. In order to ensure a stroke of the desired size for operation on the knob attached to the upper end, and to design the movement angle so that it does not become unnaturally large for operation, it is necessary to use the shift lever 5.
The length of the shift lever 50 is long (as a result, the height of the entire shift lever device becomes high), and the shift lever 50 swings in the select direction, so the shift lever 50 is not designed properly.
This poses problems, such as the need for a large horizontal installation space and a space for movement.

An object of the present invention is to solve the above-mentioned problems, and to provide a soft lever device for a vehicle equipped with an electrically or electronically controlled transmission. Although the shift lever and the knob can move or swing together, the shift lever does not move in the orthogonal direction, that is, the lateral direction, for example, in the select direction, and only the knob moves, which reduces the installation space and swing of the shift lever. It is an object of the present invention to provide a shift lever gWl for an electronically controlled transmission which is configured to reduce the moving space and to allow operation of conventional H type, double H type, etc. shift lever movement patterns.

The other points are the same as the structure shown in FIG. 1, and their explanation will be omitted.

FIG. 3(A) is a sectional view taken along line E in FIG. 1. FIG. 3(b) is a sectional view taken along the line lower of FIG. 1. FIG. 3(c) is a sectional view of the line harbor in FIG. 1. 3(d) is a sectional view taken along line 212 in FIG. 1. As is clear from these drawings, the knob 2 and the lever tube 20 can be moved relative to each other in the lateral direction, but the knob 2 and the lever tube 20 are integrally movable in the direction perpendicular to the lateral direction.

FIG. 6 is a sectional view taken along line Vl--Vl in FIG. 5. The positional relationship of the recess 23 at the end of the guide groove 27 formed in the guide plotter 10 and the contact state with the switch 25 are shown.

Another embodiment of the shift lever device for an electronically controlled transmission according to the present invention will be described with reference to FIGS. 7, 8, and 9. FIG. 8 is a sectional view taken along the line ■--■ in FIG. 7. FIG. 9 is a side view of FIG. 7.

As shown in FIGS. 7 and 9, the lever tube 20 functions as the shift lever 3 in this case. Components that are the same as those in FIG. 1 are given the same reference numerals, and their description will be omitted. A pair of arms 30 are integrally formed at the lower end of the lever tube 20, that is, the shift lever 3, and extend between the two arms perpendicularly to the shift lever 3. Bosses (not shown) are formed at each end of the arms 30. A pin 31 is inserted into the bottle hole. Further, the base plate 33 is also formed with bottle holes, and the pins 31 are configured to be inserted into these bottle holes as well. The base plate 33 and the shift lever 3 are connected by two links 32, thereby forming a parallelogram link mechanism 40. Note that the base plate 33 and the shift lever 3 are configured to rotate relative to a pin 31 press-fitted into the link 32. A loft 4 is provided at the lower end of the shift lever 3 so as to be slidable in the axial direction. ■ formed on the tip of the rod 4 or on the base plate 33
(The stroke of the shift lever 3 is limited because it is always in contact with the bottom surface of the guide groove 35 of the type or double H shape. Also, the bottom surface of the guide 435 is formed to correspond to the arcuate locus of the link 32. Furthermore, since a guide groove 35 is formed on the bottom surface of the rod 4, the lower end of the rod 4 fits into the four parts 36, 37, 38, thereby locking the shift lever 3 at a desired position. 3
The boss 41 is fitted into the link 32 and rotatably attached to the pin 31. The rod 4 can move the guide a35.

As a result, the knob 2 is configured to move in an H-shaped or double H-shaped movement pattern in the front, rear, left, and right directions. Recesses are formed in the bottom of the guide groove 35 at the neutral position 37 and the shift gear position 36.38, and an electric scratcher or switch 34 is provided at the shift gear position Z36.38.

Therefore, the tip of the loft 4 is at the shift gear position 36.3.
8, the switch 34 is turned on.

To provide the electrodes, as shown in FIG. 8, the base plate 33 may be integrally molded with the electrodes using resin, and then cutting may be performed to form the recesses. Further, although not shown, an electrode may be provided on the rod, and the rod may be provided on the base plate side and a guide groove may be formed on the shift lever side.

The electronically controlled shift lever device for transminosilane according to the present invention is constructed as described above and operates in the following 24-order manner.

First, the operation of the embodiment of the invention shown in FIGS. 1 to 6 will be described.

The state shown in FIG. 1 is a state in which transminosilane is in a neutral position. As shown in Figure 2, knob 2
is configured to be able to slide in the left and right direction (the right direction is shown in the figure) with respect to a lever tube 20 fixed to the shift lever 3, and an electrical terminal or switch 15, 16 is provided at the lower end of the knob 2. Therefore, when the knob 2 is moved to the right or left, the lever tube 20 contacts the switch 15 or the switch 16, and the switch 15, 16 is turned on or off. The movement of this knob 2 is
This means that the shift lever is moving in the select direction.
3 has been selected. Further, a rod 4 is inserted into the lever tube 20, and the upper end of the rod 4 is engaged with a locking member 13 of a pin 5, and the lower end thereof is engaged with a fourth locking member 13 of a pin 5.
As shown in the figure, it is locked in the recess 21 of the locking groove 27 of the guide block 10. For example, as shown in Figure 5,
When the shift lever 3 and therefore the rod 4 are swung and brought down, the loft 4 is guided by the bottom of the locking groove 27 and rides up, and the loft 4 slides inside the lever tube 20 and rises. Then, the rod 4 comes into contact with the locking groove 13 of the bottle 5, and the knob 2
movement is restricted. Electrical terminals are also provided for this swinging movement of the shift lever 3, constituting switches 24 and 25.

In other words, the knob 2 can move in the left-right direction only when the shift lever 3 is in the neutral position. Also, the shift lever
3 is swingable in the front-rear direction only at a predetermined position in the knob 2 where the locking groove 13 of the pin 5 is located, that is, in the left-right direction (\orthogonal direction). As a result, the shift lever gW is restricted to the double-up pattern. With one hyperactive position of knob 2 and shift lever 3, that is, four switches,
The structure is such that it is possible to detect positions 1 at 6 locations in the double upper pattern. All switches in the neutral position are in the off state.

Next, the operation of another embodiment of the invention shown in FIGS. 7-9 will be described.

When the shift lever 3 is not operated, the tip of the rod 4 is prevented from returning to the neutral position 37 of the guide groove 35. When commanding a gear shift operation, the pin 5 fixed to the knob 2 is moved relative to the rod 4 to a desired selection position, and then the link mechanism 40 is moved in the direction of the desired shift gear. Shift lever 3 by swinging the
Makes 1 hyperactive. At this time, since the link mechanism 40 has a parallelogram shape, the shift lever 3 moves without swinging, and the tip of the rod 4 fits into the recess at the shift gear position 36, 38, thereby being prevented from returning. At this time, the switch 34 is turned on, and the gear shift operation to the desired gear position of the transmission is performed hydraulically.

In the case shown in FIGS. 7 to 9, the bottom surface of the guide groove 35 is formed to correspond to the arcuate locus of the link. In this case, when the shift lever 3 is operated, which gear is selected? Whether or not the operation has been performed is not clearly communicated to the operator as a different feeling. Therefore, for example, when downshifting from 4th gear to 3rd gear, if an erroneous operation such as shifting from 4th gear to 1st gear is performed, there is a risk of damage to the clutch. Therefore, in order to deal with this problem, the bottom shape of the guide groove is corrected with respect to the circular arc trajectory determined by the link, and the amount of compression of the spring that presses the rod is adjusted. Of course, it is also possible to provide a tactile sensation.

Although the embodiments of the shift lever device for an electronically controlled transmission according to the present invention have been described in detail, the present invention is not limited to the above embodiments.
The device can be installed not only on the left side of the driver's seat as in the past, but also on the door pad, etc. That is, since this shift lever device requires only a narrow range of movement, the armrest of the vehicle door can be incorporated into the door in a state where it protrudes from the pad section normally installed in the section or a region near the pad section. In other words, the movement range of this shift lever device, that is, the moving distance, is extremely short, and this shift lever device can be installed even in a narrow space near the driver's seat of a vehicle, and can also be installed in the door as described above. can. That is, the present invention does not deviate from the spirit of the technique 4+7 concept constituted by the matters described in the claims (although it goes without saying that various design changes can be made within the scope thereof).

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following effects. That is, the shift lever device for electronic 1J control transmission according to the present invention is configured such that the knob is movable in the lateral direction with respect to the shift lever, and the switch is turned on in accordance with the operating position to which the knob is moved. - Since the shift lever is configured to be turned off, movement in the negative direction, for example, the select direction, can be achieved using only the knob, and the installation space and swinging space for the shift lever can be reduced. In addition, the shift lever is configured to be movable in the direction perpendicular to the lateral direction, and the switch is turned on and off in accordance with the operating position to which the shift lever moves. The movement pattern of the shift lever can be obtained. A locking member having a plurality of grooves is fixed to the knob, a plurality of grooves are formed in a guide member provided on the mounting member side of the shift lever, and a rod is inserted between the two grooves. Since the members are arranged, the shift lever can be accurately and quickly shifted to the operating position.

That is, conventionally, in order to swing the shift lever and reliably turn on and off the switch, a large swing angle of the shift lever was required. Since the shift lever does not move and the knob containing the switch moves only slightly in the lateral direction, space is saved and the shift lever is small. Therefore, the shift lever device can also be installed in a door pad portion or the like. Further, if the shift lever device according to the present invention is applied to the center console portion, there will be more space in the lateral direction, and other spaces, levers, etc. can be installed in parallel. Furthermore, even though there is little lateral movement, conventional shift patterns such as H-type and double-H type can be adopted without user confusion (very convenient, etc.). It is effective.
