Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an AT shift lever device for an automobile, which generates an electric output for upshifting and downshifting by a momentary operation. The momentary operation means an operation in which the shift lever moves when operated, but automatically returns to the origin when the hand is released.

  There are many types of AT shift lever devices, and an AT shift lever device having an AT mode range and an MT mode range is disclosed in, for example, Japanese Patent Application Laid-Open No. H11-157,97. The structure is such that a select operation is performed on the mode side, and then an operation of upshifting and downshifting is performed. In this specification, the range in which the shift-up and shift-down operations are performed is called an M range.

  Further, in addition to the structure disclosed in Patent Document 1 in which the range of the shift lever is detected by a switch and transmitted to the transmission as an electric signal, when the shift lever is operated between the P range and the D range, a push-pull is applied to the shift cable. An AT shift lever device has been developed in which an operation is performed to reliably transmit the transmission to a transmission, and an operation of shifting up and down is transmitted to the transmission as an electric signal. In such an AT shift lever device as well, the M range for shift-up and shift-down operations is arranged to be shifted in the left-right direction, and also has a structure that requires a select operation.

  However, conventional AT shift lever devices that require a select operation inevitably have a large width, and the right-hand drive vehicle and the left-hand drive vehicle need to have a symmetrical shape. There was a problem that the lever device had to be manufactured.

JP 2010-36709 A

  Therefore, an object of the present invention is to provide a push-pull operation to a shift cable when a shift lever is operated between a P range and a predetermined range without requiring a select operation, and to perform a momentary operation in an M range. It is an object of the present invention to provide an AT shift lever device which can be operated.

  The present invention made in order to solve the above-described problem is an AT shift lever device that generates a push-pull operation and an electric output of a shift cable by performing a shift operation of a shift lever supported by a retainer, A first shaft and a second shaft extending in a direction perpendicular to the shift direction are formed at an upper portion and a lower portion of the sub-assembly, and a second shaft is provided on the retainer while the shift lever is shifted from the P range to a predetermined range. And a second bearing portion serving as a rotation center of the shift lever in response to the first shaft, and a first bearing portion serving as a rotation center of the shift lever receiving the first shaft during further shifting operation from the predetermined range. Is extracted as a push-pull operation of the shift cable, and the movement of the second axis is extracted as an electric output of the detection switch.

  Preferably, the first shaft is a connection pin of a shift cable. The second shaft has a long diameter portion and a short diameter portion, and the second bearing portion has a slide groove in which the second shaft can slide when the shift lever is further shifted from the predetermined range. Is preferred. It is preferable that the slide groove has a structure in which a detection switch for detecting the movement of the second shaft is provided. Further, it is preferable that a plate spring having a curled tip is provided in the slide groove, and the curl center is aligned with the second axis.

  According to the AT shift lever device of the present invention, a first axis and a second axis extending in a direction perpendicular to the shift direction are formed at an upper portion and a lower portion of a lever subassembly, and the shift lever is operated to shift from a P range to a predetermined range. During this operation, the second bearing portion is used as the rotation center of the shift lever, and during further shifting operation from a predetermined range, the first bearing portion is used as the rotation center of the shift lever. Therefore, while the shift lever is shifted from the P range to the predetermined range, the first axis can be moved around the second axis, and the push-pull operation of the cable can be performed using this movement. Further, during further shifting operation from the predetermined range, the first axis does not move, so that the cable is fixed, and the momentary operation of the second axis can be detected by the detection switch to output an electric signal. .

  As described above, since the AT shift lever device of the present invention does not require a select operation, it can be used for both right-hand drive vehicles and left-hand drive vehicles, and the manufacturing cost can be reduced. If a leaf spring having a curled tip is provided in the slide groove and the curl center and the second axis are arranged so as to be aligned with each other, the second operation is performed while the shift lever is shifted from the P range to the predetermined range. Since the shaft does not move, the leaf spring does not bend, and when the shift operation is further performed from the predetermined range, the leaf spring bends, and the momentary operation can be performed.

It is an enlarged view of a 2nd bearing part. It is a side view in a P range. It is a partial sectional view in a P range. It is a side view in N range. It is a side view in D range. It is a side view in a DM range. It is a partial sectional view in a DM range.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is an overall perspective view of an AT shift lever device according to an embodiment, and FIG. 2 is an exploded perspective view thereof. In these figures, reference numeral 10 denotes a hollow layout bracket, on the bottom of which a mounting portion 11 for attaching to a vehicle body is formed. A hollow retainer 12 is attached to an upper portion of the layout bracket 10.

  Reference numeral 13 denotes a lever subassembly, on which a shift lever 14 and a shift knob 15 are attached. A first shaft 16 extending at right angles to the shift direction is provided at an upper portion of the lever subassembly 13, and a second shaft 17 extending at right angles to the shift direction is provided at a lower portion. The first shaft 16 is a connection pin of a shift cable, and is connected to an end of the shift cable, not shown. The end of the second shaft 17 has a shape in which the lower surface 18 of the cylinder is substantially flattened, and a long diameter portion and a short diameter portion are formed.

  A shift gate 19 for shifting the shift lever 14 is formed on the upper surface of the retainer 12. As shown in FIG. 3B, the shift gate 19 of the AT shift lever device of the present invention extends linearly in the shift direction, and does not have a select operation unlike the conventional pattern shown in FIG. 3A. Shape. In this embodiment, when the shift lever 14 is operated between the P range and the D range, a push-pull operation of the shift cable occurs. However, when the shift lever 14 is operated from the D range to the M range, the movement of the shift cable is canceled, and the electric output is reduced. Only.

  As shown in FIG. 2, concave and convex detent grooves 20 are formed on the side surface of the retainer 12. As in the prior art, a detent lever 21, a detent rod 22, and a spring 23 are provided inside the shift lever 14. The detent lever 21 is a member that protrudes from the long hole 24 of the lever subassembly 13 and is pushed up by the spring 23 to engage with the detent groove 20. The rod 22 is a member that pushes down the detent lever 21 against the spring 23, and its upper end reaches the knob button 25 of the shift knob 15. Therefore, when operating the shift lever 14 between the ranges indicated by black arrows in FIG. 3, the shift operation cannot be performed unless the knob button 25 is pressed.

  Further, on the side of the lever sub-assembly 13, a moderating pin 27 resiliently provided by a spring 26 is provided. The tip of the moderating pin 27 is formed on the back surface of the ceiling of the retainer 12 as shown in FIG. Abuts on the moderation uneven portion 28. This provides a sense of moderation when the shift lever 14 is shifted. However, these detent structure and moderation structure are the same as those in the related art, and are not the main part of the present invention.

  A second bearing 30 that receives the second shaft 17 is formed below the retainer 12. As shown in FIG. 4 in an enlarged manner, the second bearing portion 30 has a circular hole portion 31 which can receive and rotate the long diameter portion of the second shaft 17, and an arc-shaped slide groove formed on the left side thereof. 32. The slide groove 32 is formed in accordance with the trajectory of the second shaft 17 when the lever sub-assembly 13 rotates about the first shaft 16. The vertical width of the arc-shaped groove portion 32 is set so that the short diameter portion of the second shaft 17 can pass through, but the long diameter portion cannot pass through.

  A first bearing portion 33 for receiving the first shaft 16 is formed on an upper portion of the retainer 12. As shown in FIG. 5 and FIG. 6, the shape is composed of a substantially semicircular portion 34 that can be rotated by receiving the first shaft 16 and an opening 35 formed on the left side thereof. The first bearing portion 33 shown in FIGS. 5 and 6 is not shown in FIG. 2 because it is formed on the back surface of the cover 36 of the retainer 12 shown in FIG.

  In addition, a leaf spring 40 is provided in the slide groove 32 of the second bearing 30. As shown in FIG. 6, the leaf spring 40 has a curled tip 41, and the base thereof is fixed to the bottom surface of the retainer 12. As shown in FIG. 6, the curled tip portion 41 is fitted into the concave portion 42 of the second shaft 17, and constantly pushes the second shaft 17 upward. The center of the leaf spring 40 and the second axis 17 are arranged in alignment. Further, as shown in FIG. 9, an M range detection switch 45 that detects the movement of the second shaft 17 and outputs an electric signal is provided in the slide groove 32 of the second bearing 30.

  Further, as shown in FIG. 2, a position detection switch 46 is housed on the side of the retainer 12 and is covered by a cover 36. The position detection switch 46 detects a position when the shift lever 14 is operated between the P range and the D range. However, the position detection switch 46 is known per se, and is not a main part of the present invention, and therefore description thereof is omitted. I do.

Next, the operation of the AT shift lever device of the present invention will be described.
First, when the shift lever 14 is in the P range, the lever sub-assembly 13 is at the position shown in FIGS. In this state, the lower second shaft 17 is fitted in the circular hole 31 of the second bearing 30.

  When the shift lever 14 is shifted from the P range through the N range shown in FIG. 7 to the D range shown in FIG. 8, during this time, the lower second shaft 17 becomes the center of rotation, and the lever subassembly 13 rotates. For this reason, the first shaft 16 makes a large circular motion as shown by the imaginary line in FIG. 6, and moves the connected shift cable to perform the push-pull operation. For this reason, the shift operation from the P range to the D range is reliably transmitted to the transmission via the shift cable. This movement is shown as a cable output in FIG. During this time, since the second shaft 17 does not move, the leaf spring 40 does not bend, and the leaf spring 40 does not generate a load.

  In the D range, the first shaft 16 enters the substantially semicircular portion 34 of the first bearing portion 33 as shown in FIG. For this reason, even if an attempt is made to shift the shift lever 14 from the D range to the M range, the first shaft 16 cannot move any more, and the shift cable stops. When the shift lever 14 is operated in the D range as shown in FIGS. 9 and 10, the first shaft 16 becomes the center of rotation, and the lever sub-assembly 13 swings. At this time, the second shaft 17 moves inside the slide groove 32 on the arc and hits the M range detection switch 45. However, since the upper end 50 of the layout bracket 10 shown in FIG. 10 serves as a stopper, the second shaft 17 does not fall off. Further, when the hand is released from the shift lever 14, the first shaft 16 is pushed back by the load generated by the leaf spring 40, so that a momentary operation is performed in the M range, and the operation is detected by the M range detection switch 45 and output as an electric output. Removed and transmitted to the transmission.

  When the shift lever 14 is returned from the D range to the P range, the above procedure is reversed. After the D range, the lever sub-assembly 13 rotates again around the second shaft 17 as the center of rotation, and is connected to the first shaft 16. Move the shifted cable.

  In this manner, the AT shift lever device of the present invention does not require a select operation by switching the center of rotation, and when the shift lever is operated between the P range and the predetermined range (D range), the shift cable is connected to the shift cable. A push-pull operation can be performed. Since the AT shift lever device of the present invention does not perform a select operation, there is also an advantage that it can be used for both right-hand drive vehicles and left-hand drive vehicles.

  The operation of upshifting and downshifting is not performed by the AT shift lever device of the present invention, but can be performed, for example, by operating a switch provided on a steering wheel.
