Description

Shifting control device of automatic transmission with manual shift function

The present invention relates to a shifting control apparatus of an automatic transmission having a manual shift function to serve as a manual shift.

In general, the automatic transmission is automatically shifted to a shift position set in the driving mode (D) according to the driving state of the vehicle and the degree of the accelerator pedal of the driver so that the shift is made.

In this way, the automatic transmission is shifted to reflect the driving conditions of the vehicle rather than reflecting the driver's intention in the driving mode (D) state.

Therefore, if the automatic transmission is the driver's intended shift, it is possible to obtain a shift sense obtained from the manual transmission, which can be expected to have a maneuverable start and acceleration of the vehicle indicated by the driver selecting an appropriate shift.

A shift control apparatus of a conventional automatic transmission having such a manual transmission is shown in FIG. 1.

As shown, the base 10 is installed on the body of the vehicle (not shown), and pivotally coupled to the base 10 so as to be rotated left and right, and the selector pin guide surface 12a, shift position P, A shift block 12 having a latching jaw 12b for distinguishing R, a locking groove 12c for determining a shift position P position, and a cross pivot axis 13 coupled to the shift block 12 before and after A selector lever 14 having a selector pin 14A that is rotatable and slides on an upper surface of the shift block 12 and pivotally coupled to the base 10 on a pivot axis of the selector lever 14 The yoke 16 for operating the cable connected to the automatic transmission by being bitten by the selector lever 14 when shifting, and when the selector lever 14 is switched to the manual mode on the opposite side of the yoke 16, Detection switch for detecting manual operation of the selector lever 14 Includes the assembly 20 and the automatic shift mode and a manual shift mode switching position when the stop for holding this pin 22 of the shift block 12.

The conventional shifting control device configured as described above operates as follows.

1 shows that the selector lever 14 is switched to the position in the automatic shift mode, and the selector lever 14 is bitten by the inner surface of the yoke 16.

As the selector lever 14 is moved to the shift positions P, R, N, D, 2, and 1 in such an automatic shift mode, the selector lever 14 rotates about the pivot axis 13 and the selector pin 14A. ) Is positioned in the engaging groove 12c and the guide surface 12a of the shift block 12.

At this time, according to the rotation of the selector lever 14, the yoke 16 bite is rotated together, and thus, an unillustrated cable connected to the yoke 16 controls the automatic transmission.

On the other hand, when the driver wants to switch to the manual shift mode in such a state, when the selector lever 14 is turned to the left in the X direction indicated by the arrow, the shift block 12 rotates to the left side together with the selector lever 14. The combination of the selector lever 14 and the yoke 16 is released and simultaneously the selector lever 14 and the detection switch assembly 20 are bitten.

At this time, the stop pin 22 serves to maintain the shift block 12 rotated to the left in the rotated state.

In this state, the limit switch 26 disposed on one side of the shift block 12 is turned on to control the transmission in an appropriate driving state of the vehicle.

Afterwards, if the driver wants to increase the vehicle's driving speed, the detection switch assembly 20 is ON in proportion to the number of times the selector lever 14 is pushed, and at this time, the speed of the transmission speed is increased and the selector lever is increased. The detection switch assembly 20 is turned ON in proportion to the number of times the pulley 14 is pulled down, and the gear speed of the transmission speed decreases every time.

The shift control device of the conventional automatic transmission configured and operated as described above has the following problems.

In the above, when the selector lever 14 is switched from the manual shift mode to the Y-direction position in the automatic shift mode, the selector lever 14 should be smoothly engaged with the yoke 16, but not only the structural play occurs but also the selector lever. Since the plane of the lower end of (14) and the edge of the yoke 16 are in contact with each other, the bite of the bite becomes difficult and the manual mode is difficult to release.

In addition, after the driver selects the automatic shift mode or the manual shift mode, the driver may move to the original position by inadvertent external force without the driver's selection, which is likely to cause a malfunction.

And since the selector pin 14A can move relatively freely on the guide surface 12a of the shift block 12 without the driver's button manipulation, it is difficult for the driver to select the selector lever 14 at the correct shift position. It was also difficult to recognize easily.

This is summarized as follows.

First, since there is no function of preventing malfunction when the manual transmission mode is selected and released, the driver needs to make an effort to accurately select when selecting and releasing the manual transmission mode. This can cause malfunctions while driving and put the vehicle at risk.

Secondly, when the shift positions " P, R, N, D, 3, 2, 1 " of the automatic shift mode are selected, there is no function in which the shift lever is moved only by the driver's button operation.

Third, when the selector lever is initially installed in the vehicle, it is easy to make initial setting work and the selector lever can be easily moved to each position of "P, R, N, D, 3, 2, 1" without the driver paying close attention. There is no function to select.

The present invention is to solve the above problems and problems, to facilitate the selection and release of the manual shift mode, to enable the selector lever to move only by the operator's button operation, and to ensure the correct position in the automatic shift mode. The purpose of the present invention is to allow the driver to easily recognize whether the selection is completed, and to reduce the manufacturing cost and size, and to provide a shift control device for an automatic transmission having a manual transmission function with a low weight.

Reference numeral 140 denotes a cable operating bracket.

The cable actuating bracket 140 is inserted into and fixed to one side wall 103 of the base 100 so as to interlock a transmission-side cable (not shown) in combination with the selector lever 120 when the automatic mode of the selector lever 120 is selected. It is rotatably installed.

Accordingly, when the selector lever 120 is switched to the position of the automatic shift mode to select a shift position, the cable operating bracket 140 is rotatable on the X-axis line.

In addition, the cable operation bracket 140 is provided with a selector lever holding jaw 141 on the inner wall for connecting the selector lever 120 to the automatic shift mode.

When the selector lever 120 is switched from the position of the right manual mode to the position of the left automatic mode, the selector lever 120 can be inserted into and detached from the selector lever holding jaw 141 in diameter.

Therefore, when the selector lever 120 is switched to the manual mode side, the selector lever 120 is connected to the cable automatic bracket 140 even if the correct force direction is not correct.

Reference numeral 150 is a switching lever.

The switching lever 150 is pivotally coupled on the X-axis of the right side wall 103 of the base 100 to be rotatable in combination with the selector lever 120 during manual mode shifting of the selector lever 120.

The switching lever 150 has a selector lever holding jaw 151 protruding toward the selector lever 120 at an upper end thereof.

Return springs 160 and 161 are assembled to the manual mode detection switch assembly 170 as elastic means for returning the switching lever 150 to the neutral position when the selector lever 120 is moved forward or backward in the manual mode.

The manual mode detection switch assembly 170 is composed of a detection switch (not shown) for sensing the increase and decrease of the manual shift mode when the selector lever 120 is engaged with the switching lever 150 to operate the selector lever 120. do.

Automatic and manual mode selection holding means 300 for maintaining the selected state with elastic force when the manual mode or the automatic mode of the selector lever 120 is connected or released, the stopper is provided on the bottom surface of the pivot shaft 110 A lever 301, an actuating rod 302 having one end connected to the stopper actuating lever 301 and having cam faces 302A, 302B at the other end, and sliding of the actuating rod 302 on the base 100; A pin housing 303 for supporting reciprocation, and a push pin 304 for pressing the cam surface 302A or 302B of the actuating rod 302 with the force of the elastic spring 305 in the pin housing 303. have.

On the other hand, whenever the selected position of the selector lever 120 is selected during the automatic mode operation of the selector lever 120, the automatic transmission position maintaining means 190 for maintaining it at a predetermined elastic force in the correct position, the cable operation On the upper surface of the bracket 140, a plurality of consecutive positioning valleys 142A to 142G corresponding to shift positions P, R, N, D, 3, 2, and 1 of the selector lever 120 are formed, and the base A leaf spring 191 having one end fixed to the other end and an elastic force acting downward at all times, and a rotating roller 192 seated on the selected positioning bone at the other end of the leaf spring 191. Is composed.

The operation state of this embodiment configured as described above is divided into automatic mode and manual mode.

First, the state of the automatic mode of the automatic transmission will be described.

In the automatic mode, the selector lever 120 is vertically placed, and the pivot shaft 110 is fixed because the actuating rod 302 is fixed by the push pin 304 receiving the elastic spring 305 force. To keep it.

That is, the lower end of the push pin 304 is pressing the left cam surface 302A of the actuating rod 302 with the compressed elastic spring 305 force.

At this time, the lower cylindrical portion of the selector lever 120 is inserted into the selector lever holding jaw 141 of the cable operation bracket 140.

The pin 122 of the selector lever 120 is located on the positioning surface 132B, which is a side surface of the step 132 of the shift positioning plate 130, and the rotary roller 192 installed on the leaf spring 191 is a cable. It is in the state selected for the valley 142C of the operation bracket 140. (See Fig. 3)

In such a state, to move the selector lever 120 to the position of R, it is only necessary to pass the pin 122 through the step 132 by operating a button not shown.

In order to move to the position of P again, the pin 122 is passed over the stepped step 131 in the same manner.

Since the vehicle is normally parked at the position P, in order to select the selector lever 120 at the position D of the travel mode after starting the vehicle, the vehicle may be positioned on the positioning surface 133A by passing over the steps 131 and 132.

In this way, if three steps are desired while driving in the D mode, the selector lever 120 is pulled backwards, and at the same time, the button 122 is operated to turn over the pin 122 from the step 133 and the positioning surface 133B is moved. can do.

On the other hand, the second stage and the first stage can also achieve the desired shift by passing the pin 122 over each step (134, 135) in the same way.

As such, when the selector lever 120 is operated, the cable connecting bracket 140 connected through the holding latching jaw 141 rotates about the X axis and rotates the roller 192 every time the positioning of the select lever is made. Is elastically in close contact with any one of the valleys 142A to 142G.

Therefore, in the automatic mode, unlike the related art, the shift positions P, R, N, D, 3, 2, and 1 may be determined only by operating a button on the side of the select lever 120. Furthermore, the selector lever 120 may be determined. Whenever the position of is determined, the automatic transmission position holding means 190 increases the reliability of the determination.

In addition, each time the rotary roller 192 hits the selected bone, it may be transmitted to the selector lever 120.

B) Explain the manual mode of automatic transmission.

When the selector lever 120 is flipped in the S direction of FIG. 2 when the automatic mode is to be switched to the manual mode as described above, the selector lever 120 is supported by the pivot shaft 110 while being supported by the cable operating bracket 140. ), And the operating lever 301 rotates to the left side together with the selector lever 120.

At this time, with the rotation of the pivot shaft 120, the actuating lever 301 integrated with the pivot shaft 120 pulls the actuation rod 302 to the left side, while the actuation rod 302 is supported by the pin housing 303 to the left. Go to.

Accordingly, the lower end of the push pin 304 is pressed against the selected cam surface 302B on the right side by the left side movement of the operating rod 302, thereby maintaining the rotation of the selector lever 120 flipped to the right side. Is released.

In this state, the shirkuck lever 120 is inserted into the holding locking jaw 151 of the switching lever 150 on the right side.

At this time, as described above, even if the direction in which the selector lever 120 enters the holding latch 151 of the switching lever 150 is not correct, the lower end of the selector lever 120 is configured as a cylindrical portion, so that a smooth insertion is possible.

At the same time, the manual mode detection switch assembly 170 automatically detects the current driving state of the vehicle and selects the vehicle in the desired number of stages.

After the driver pushes the selector lever 120 forward to increase the number of times, the front return spring 160 is compressed by the switching lever 150 connected to the selector lever 120, and then the selector lever 120 is pushed again. When it is returned to the M position, a detection switch (not shown) detects this and raises the number of stages.

In order to continuously increase the second stage, the above operation may be added once more.

On the other hand, in order to lower the manually shifted gear stage, when the selector lever 120 is pulled back to the contrary, the rear return spring 161 is compressed by the switching lever 150 connected to the selector lever 120. Afterwards, the selector lever 120 is returned to the M position. At this time, an unshown detection switch in the detection switch box 173 senses this and reduces the number of stages.

According to the present invention configured and operated as described above, the selector lever 120 is easily connected to and released from the switching lever 150 at the time of selecting and releasing the manual shift mode, thereby reducing the possibility of malfunction. Therefore, the driver selects the manual shift mode. There is no need to make an effort to make a correct selection upon release. This ensures high operational reliability while driving, which can prevent dangerous situations in the vehicle.

In addition, when selecting the shift positions "P, R, N, D, 3, 2, 1" of the automatic shift mode, the selector lever 120 is moved only by the driver's button operation, so that accurate position control can be achieved. can do.

In addition, when the selector lever 120 is initially installed in a vehicle, the automatic shift position holding means 190 facilitates initial setting, and the selector lever is set to " P, R, N without careful attention. , D, 3, 2, 1 "can be selected easily.

Meanwhile, in the above embodiment, the positioning plate 130 and the cable operating bracket 140 are disposed on the left side of the base 100 and the switching lever 150 and the manual mode detection switch assembly 170 are disposed on the right side thereof. It will be within the technical scope of the present invention to configure the position by changing each other.

As described above, according to the present invention, when the manual shift mode is selected and released, no accurate operation is required, and the selector lever is moved only by the operator's button operation to enable accurate position control, and the correct position can be selected in the automatic shift mode. Therefore, the driver can easily recognize whether the selection is completed, and also has the advantage of reducing the production cost and size and weight.
