Description
- 1. Field of the Invention[0001]
- The present invention relates to a shift switch control device for selection lever units of automatic transmissions and, more particularly, to a shift switch control device for selection lever units of sport mode-type automatic transmissions capable of selectively performing an automatic transmission mode or a manual transmission mode as desired, the shift switch control device designed to accomplish a reliable up-shift operation, so-called a “+” shift operation, and a reliable down-shift operation, so-called a “−” shift operation, during a manual transmission mode, and to be reduced in the number of its parts, thus being preferably simplified in its construction.[0002]
- 2. Description of the Prior Art[0003]
- In recent years, sport mode-type automatic transmissions, designed to allow drivers to select an automatic transmission mode or a manual transmission mode as desired in accordance with driving conditions and/or driver's tastes while driving, have been developed and proposed to be equipped within, particularly, a variety of expensive luxury cars.[0004]
- Different from conventional transmissions with a fixed automatic transmission mode or a fixed manual transmission mode, such sport mode-type automatic transmissions allow drivers to enjoy the driving feeling to the full while selecting the automatic transmission mode or the manual transmission mode as desired in accordance with driving conditions and/or their tastes while driving their cars.[0005]
- Such a sport mode-type automatic transmission is provided with a selection lever unit for allowing a driver to perform a desired shifting operation. The construction of a conventional selection lever unit for such sport mode-type automatic transmissions is shown in FIGS. 7, 8 and[0006]9. As shown in the drawings, the conventional selection lever unit has a
selection lever 100, which is installed within amain frame 111 and is used for selecting a desired mode or a desired range within atransmission pattern 110 having a manual transmission mode and an automatic transmission mode. Acable bracket 113 is connected to a shift cable (not shown) at a position around theselection lever 100. Theabove cable bracket 113 is operated in conjunction with theselection lever 100 when the automatic transmission mode is selected, thus actuating a transmission manual valve (not shown). - The[0007]
selection lever 100 has twoconnection protrusions 114, while thecable bracket 113 has aconnection lever 115 at a position corresponding to theconnection protrusions 114. Therefore, theselection lever 100 is operated in conjunction with thecable bracket 113 through the engagement of the twoconnection protrusions connection lever 115 during an automatic transmission mode. - The conventional selection lever unit has a shift switch control device of FIG. 9. As shown in the drawing, the conventional shift switch control device for selection lever units comprises a manual[0008]
mode select switch 103, an up-shift switch 101, a down-shift switch 102 and a switch actuation unit, which are provided on the top wall of themain frame 111. The up-shift switch 101 and the down-shift switch 102 are used for performing the up- and down-shifting operations when the manual transmission mode is selected by theselection lever 100. - In such a case, the up-[0009]
shift switch 101 is positioned at the front portion of the shift switch control device, while the down-shift switch 102 is positioned at the rear portion of the control device. In addition, the manualmode select switch 103 is positioned between the up-shift switch 101 and the down-shift switch 102. - Two shift[0010]
switch actuation members shift switch 101 and the down-shift switch 102, with a gap defined between the two shiftswitch actuation members selection lever 100, thelever 100 is inserted into the gap defined between the two shiftswitch actuation members mode select switch 103. - In each of the two shift[0011]
switch actuation members tipping bar 108 is set within ahousing 106 while being normally biased by areturn spring 107 at its rear end, thus normally positioning theselection lever 100 at a neutral position. - Therefore, when the[0012]
selection lever 100 is moved to perform a desired shifting operation, thetipping bars 108 of the two shiftswitch actuation members shift switches switches - In such a case, the manual[0013]
mode select switch 103 is continuously operated by a side surface of theselection lever 100, thus being maintained at its activated state. - However, such a conventional shift switch control device for selection lever units of automatic transmissions is problematic in that it is very difficult to maintain the precise actuation gaps between the[0014]
tipping bars 108 and the up- and down-shift switches tipping bars 108 is different from the operational direction of the up- and down-shift switches - In addition, it is very difficult to manufacture the tipping bars, and so the tipping bars are very expensive. Another problem experienced in the conventional shift switch control device resides in that it has a complex construction and is not easy to install within a limited area.[0015]
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a shift switch control device for selection lever units of automatic transmissions capable of selectively performing an automatic transmission mode or a manual transmission mode as desired, which is designed to accomplish a reliable up-shift operation, so-called a “+” shift operation, and a reliable down-shift operation, so-called a “−” shift operation, during a manual transmission mode, and which is reduced in the number of its parts, thus being preferably simplified in its construction.[0016]

projection 17 is formed at one side of the central portion of therotary plate 13 while being directed to theselection lever 9. - A[0037]
manipulation lever 19 is installed at the top of theselection lever 9 such that themanipulation lever 19 is positioned between the up- and down-shift switches transmission mode pattern 3. Themanipulation lever 19 thus turns on or off the up- or down-shift switch selection lever 9. - The[0038]
above manipulation lever 19 comprises ahorizontal part 21 and avertical part 23. Thehorizontal part 21 has a predetermined length such that thepart 21 does not come into undesired contact with the up-shift switch 5 when theselection lever 9 is moved from the D-stage to the M-stage. Thevertical part 23 extends from the tip of thehorizontal part 21 downward to a predetermined length so as to selectively come into contact with the up- and down-shift switches shift switches - A[0039]
projection guide plate 25 is provided on theselection lever 9 at a position corresponding to theprojection 17 of therotary plate 13 under themanipulation lever 19. Aninclined surface 27 is formed at one end of theprojection guide plate 25. Thisinclined surface 27 prevents the up-shift switch 5 from coming into undesired contact with themanipulation lever 19 when theselection lever 9 is moved from the D-stage to the M-stage. In such a case, theprojection 17 pushes therotary plate 13 outward, thus allowing themanipulation lever 19 to be positioned in the gap between the up- and down-shift switches - The[0040]
projection guide plate 25 also hasflat guide surface 29, which linearly guides a movement of theprojection 17 when theselection lever 9 at the M-stage performs an up- or down-shifting operation. - In order to give an elastic returning force to the[0041]
rotary plate 13 when theselection lever 9 is moved from the M-stage to the D-stage, a return means is provided. In the preferred embodiment, this return means comprises asupport bracket 31 mounted to thehinge shaft 11 at the outside of therotary plate 13, with areturn spring 33 positioned between therotary plate 13 and thesupport bracket 31. - The operation of the above shift switch control device of this invention will be described herein below with reference to FIGS. 3, 4,[0042]5 and6.
- In FIG. 3, the[0043]
selection lever 9 is positioned at the D-stage of the automatictransmission mode pattern 1, while therotary plate 13 is positioned at the M-stage of the manualtransmission mode pattern 3. In addition, theprojection 17 of therotary plate 13 is positioned on theinclined surface 27 of theprojection guide plate 25 of theselection lever 9 as shown in FIG. 4. - In such a case, the up- and down-[0044]
shift switches vertical part 23 of themanipulation lever 19 relative to the rotating direction of theselection lever 9. In addition, therotary plate 13 is elastically supported by thereturn spring 33. - When the[0045]
selection lever 9 is moved from the D-stage of the automatictransmission mode pattern 1 to the M-stage of the manualtransmission mode pattern 3 as shown in FIGS. 5 and 6, theprojection 17 of therotary plate 13 is pushed outward by theinclined surface 27 of theprojection guide plate 25 of theselection lever 9. Therefore, therotary plate 13 is pushed outward, and so it is possible for theselection lever 9 to be moved from the D-stage of the automatictransmission mode pattern 1 to the M-stage of the manualtransmission mode pattern 3 without allowing themanipulation lever 19 to be brought into undesired contact with the up-shift switch 5. - The[0046]
selection lever 9 is thus completely moved to the M-stage of the manualtransmission mode pattern 3, thereby selecting the manualtransmission mode pattern 3. When theselection lever 9 in the above state is moved forward, thelever 9 turns on the actuation button of the up-shift switch 5, thus performing a desired up-shifting operation. On the other hand, when theselection lever 9 is moved backward, thelever 9 turns on the actuation button of the down-shift switch 7, thus performing a desired down-shifting operation. - In addition, the transmission mode shifting operation for shifting the mode from the M-stage to the D-stage is accomplished by reversely performing the above-mentioned transmission mode shifting operation for shifting the mode from the D-stage to the M-stage, and further explanation is thus not deemed necessary.[0047]
- As described above, the present invention provides a shift switch control device for selection lever units of automatic transmissions capable of selectively performing an automatic transmission mode or a manual transmission mode as desired. In the shift switch control device, the actuated direction of the actuation buttons of the up- and down-shift switches is equal to that of the manipulation lever of the selection lever practically actuating the up- and down-shift switches, thus accomplishing a desired operational reliability of the shift switch control device during a manual transmission mode. The shift switch control device of this invention is also reduced in the number of its parts, thus being preferably simplified in its construction. The shift switch control device is thus easily manufactured at a low production cost, and is easily installed within a limited area.[0048]
- Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.[0049]
