Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention operates a transmission for a vehicle of a type in which five shift positions of reverse (R), neutral (N), hold (H), shift up (U), and downshift (D) are selected by an operating lever. The present invention relates to a lever operating device.

[0002]

[Prior art]

 A mechanical electronically controlled transmission that electrically operates a manually operated transmission is known to facilitate driving of a vehicle. An operating lever actuating device called a shift tower, which sends the variable speed position to the transmission by an electric signal, has, for example, as shown in FIG. 7, R, N, H, U, and D shift positions. Some are arranged in a letter pattern.

That is, in FIG. 4, the operation lever 15 is configured to swing in the select direction (H-N) together with the lower lever 17 about the shaft 16 mounted by the shaft 16 a in a curved groove (not shown) of the lever bracket 20. It is provided in. Further, the lower end of the lower lever 17 is engaged with one recess of the select positioning unit 17 having three recesses 18 by a select pin 19 biased downward by a spring 20.

Further, referring to FIG. 5, the operation lever 15 is configured to be swingable in the shift direction (UD) with the select pin 19 as a fulcrum together with the inner shaft 16 and the lower lever 17.

Referring also to FIGS. 6 and 7, when the operating lever 15 is operated in the shift direction, the piston 21 is provided inside the inner shaft 16 and is urged outward by a spring 22. One of the contacts 21 and 21 hits the lever bracket 20 to generate an operation force. A pattern guide 23 is provided on the casing (not shown).

Therefore, when the operation lever 15 is operated along the pattern guide 23, only the engagement between the select pin 19 and the concave portion 18 gives a feeling of operation in the select direction (H-N), and the shift direction (U -D), the spring 22 generates an operating force.

[0007]

[Problems to be solved by the device]

 However, the above-mentioned technique has a large number of components and a complicated structure.

Further, there is a problem that the strength of the guide structure, particularly the rigidity, is insufficient, and the operation feeling is not good.

[0009] Although Japanese Patent Application Laid-Open No. 1-120225 by the present applicant is disclosed, since it is composed of a check pin and a recess, it has the same problem as the above technique.

Therefore, an object of the present invention is to provide an operation lever actuating device for an automobile transmission, which has a good operation feeling, has a small number of parts, and has a simple structure.

[0011]

[Means for Solving the Problems]

 According to the present invention, a transmission for a vehicle of a type in which five shift positions of reverse (R), neutral (N), hold (H), shift up (U), and shift down (D) are selected by an operating lever. In the operating lever actuating device, the guide plate that moves in a plane together with the operating lever is provided in the hole of the frame at a position away from the turning point of the operating lever, and the guide plate has a valley at the H position on one side. A tapered surface is formed, recesses are provided at the N position and the R position on the other side, and check pins that are pressed by springs are provided on both sides of the guide plate. Further, the frame body is guided at the R position. Protrusions are provided to engage the grooves in the plate.

[0012]

In the operation lever operating device for a vehicle transmission having the above-described structure, when the driver moves the operation lever in the shift direction such as U and D, the operation feeling that the operation force increases according to the stroke There is.

Also, when moving like N-R, there is a feeling that it is out of N, and when shifting to R, the groove of the guide plate and the protrusion of the frame engage, so be sure. Can be held in R.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the description, first, the configuration of the portion related to the conventional technique will be described.

In FIG. 1, a transmission 26 is attached to an engine 31 via a clutch housing 32, and the clutch housing 32 is provided with a position sensor 33 for detecting a gear shift position.

Further, the transmission 26 includes a gear set unit 34 for gear-shifting by an electric signal from the transmission control unit (T / M control unit) 25, a range-shift actuator 36 for range-shifting, a splitter actuator 37 for splitter-shifting, and a gear rotation sensor. 38 and 38 are installed.

The clutch pedal 43 is provided with a clutch switch 41 for detecting clutch disengagement and contact, and a reaction force magnetic valve 44 for notifying the driver of completion of gear setting.

Next, the position sensor 33, gear set unit 34 gear, gear rotation sensor 38, clutch switch 41, reaction force magnetic valve 44, display monitor 40, and magnetic valve 39 are electrically connected to the T / M control unit 25. Connected by a circuit.

The shift tower 1, which is an operation lever operating device, is connected to the control unit 25 by an electric circuit.

2 and 3, the frame 2 has a hole 2d, and a guide plate 3 is provided in the hole 2d slidably between covers 2a and 2b attached to the upper and lower parts of the frame. It has been done.

A tapered surface 6 having a valley at the H position is formed on one side of the guide plate 3, and recesses 7 and 8 are provided at the N position and the R position on the other side, respectively, and at the N position. Grooves 5 are provided on the adjacent sides so as to engage with the projections 9 provided in the holes 2d of the frame body 2.

Further, on the frame body 2, check pins 11 a and 11 b for pressing the tapered surface 6 of the guide plate 3 and the concave portions 7 and 8 are biased by the spring 12 in the direction of the guide plate 3, and as shown in FIG. In the state, the check pin 11b is attached with the bolt 13 so as not to contact the guide plate 3.

The turning point 10a of the operating lever 10 is supported by a bearing (not shown) provided in the casing 1a, and the casing 1a is fixed to the cover 2b via the cover 2a together with a plurality of holes 2c by bolts (not shown). The lower end of the lever 10 is slidably inserted into the hole 4 of the guide plate 3.

Therefore, if the operation lever 10 is moved in the shift direction (direction A in FIG. 3), the operation force is increased by the taper surface 6 and the check pin 11a. At this time, the check pin 11b is not in contact with the guide plate, so the operation is performed. Does not affect power.

When moving in the select direction (B direction in FIG. 3) and shifting to R, the recesses 7 and 8 and the check pin 11b are in contact with each other. There is a sense of moderation. Further, since the groove 5 and the projection 9 are engaged with each other, the R (reverse) is securely held.

[0027]

[Effect of device]

 Since the present invention is configured as described above, the structure is simple, the number of parts is small, the operation feeling and the feeling of moderation are excellent, and the guide plate and the detent mechanism are combined, so that the present invention is compact.
