Abstract

PURPOSE:To improve the safety in the present device for an automobile by constituting a priority system so as to push the lug of a changeover switch to a first speed range or a second speed range only at drive range of a shift lever. CONSTITUTION:When a shift lever 2 is in a parking range P, a reverse range R, and a neutral range N, an operation member 13 is on a position not to push a pin 12, as shown in the figure. Consequently, a plate 10 is close to the back 3a of an indicator 3 by an energizating means 14, and becomes higher than the lugs 6, 7 of a changeover switch for a first speed range and a second speed range, not to enable operation of the lugs 6, 7 through inserting holes 8, 9. When the shift lever 2 is rotationally moved to a drive range D, the operation member 13 actuates the pin 12 to bring down the plate 10 and the lugs 6, 7 can be operated. Thus, the operation error can be prevented and the safety is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shift device for an automatic transmission used in an automobile.

[Prior Art and Problems to be Solved by the Present Invention] As a conventional shift device for an automatic transmission used, for example, in the floor of an automobile, there is, for example, one shown in Japanese Utility Model Application Publication No. 60131425.

However, according to this conventional technology, since the system uses a button switch to switch between parking range, reverse range, neutral range, drive range, and 2nd and 1st speed ranges, it is possible to accidentally switch to drive range while driving at high speed. For example, there is a risk that the parking range switch may be pressed. Furthermore, there is a risk that, for example, the 2nd or 1st gear range switch may be pressed by mistake while the vehicle is moving backwards in the reverse range, and an improvement is desired.

Therefore, according to the present invention, in view of such conventional problems, two
The purpose is to enable switching to the 2nd and 1st speed ranges only when the drive range is in the drive range.

[Means to solve the problem]

In order to achieve such an object, the present invention provides a shift device for an automatic transmission that includes a shift lever that is pivotally supported on a vehicle body and can be switched only to a parking range, a reverse range, a neutral range, and a drive range, and a shift lever that is supported on the vehicle body. an indicator having an opening formed at a position close to the drive range of the shift lever and covering a base of the shift lever; A switch box located at a distance from the back side and having knobs for switching to 2nd speed and 1st speed on the front side, and a switch box that can freely move up and down between the back side of the indicator and the front side of the switch box. a plate having an insertion hole formed only in a portion corresponding to the knob of the changeover switch, and a priority system that prioritizes operation of the switch box over operation of the shift lever, - an operating member is protruded from a part of the plate at a position where it can be engaged with a pin protruding substantially horizontally from the plate, and when the shift lever is in a range position other than the drive range, a biasing means is applied to the plate; Only when the switch knob of the switch box is in the recessed position through the insertion hole and the shift lever is in the drive range, the operating member pushes down the pin and the plate moves downward to shift to the second gear or first gear, respectively. The priority system is configured such that the knob of the switch to switch to the second gear or the first gear range is pressed when the shift lever is in the drive range. The automatic transmission is characterized in that the range of the automatic transmission is switched from a drive range to a 2nd speed or 1st speed range.

[For production]

Since the present invention has such a configuration, its operation will be explained next.

When the shift lever is rotated to the parking range, reverse range, or neutral range, the operating member does not push the pin, so the plate is not brought close to or pressed against the back surface of the indicator by the biasing means. Since the position is higher than the position of the knob of the 2nd speed/1st speed changeover switch, the knob of the 2nd speed/1st speed changeover switch cannot be operated from the insertion hole formed in the plate.

Next, when the shift lever is rotated to the drive range, the operation member tilts due to the movement of the shift lever.
As the pin is moved downward and the plate integrated with the pin is moved downward, the knob of the 2nd speed/17 changeover switch is exposed from the insertion hole formed in the plate, allowing you to switch to 2nd speed or 1st speed. becomes possible.

Of course, it goes without saying that when the shift lever is rotated to drive range, neutral range, reverse range, and parking range, the gear of the automatic transmission changes to each range.

Therefore, while the shift lever is in the drive range,
By pressing either the 2nd or 1st gear switch, the priority system allows the range to be switched to 2nd or 1st gear.

At the same time, unless the shift lever is set to the drive range, the switch knob for switching between 2nd and 1st speeds cannot be operated, so even if the shift lever is not in the drive range, the switching operation between the 2nd and 1st speed ranges will not be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of an embodiment of the present invention will be described below with reference to the drawings.

1 to 3 are diagrams showing one embodiment of the present invention, and reference numeral 1 denotes a shift device of an automatic transmission, which is pivotally supported on a floor panel (not shown) which is a vehicle body, and has a parking range P, a reverse range R, neutral range N, and a shift lever 2 that can be switched only to drive range D; an opening 4 is formed in a position supported by the vehicle body and close to drive range D of shift lever 2; An indicator 3 that covers the base 2a is arranged at a position protruding through the opening 4 formed in the indicator 3, and is arranged at a position spaced apart from the back surface 3a of the indicator 3. The switching switch 5 is arranged to be movable up and down between the back surface 3a of the indicator 3 and the front surface 5a of the switch box 5, and the switch switch 5 has knobs 6 and 7 for the switching swifts, respectively. Plate 1 with insertion holes 8.9 formed only in the portion corresponding to .7.
0 and a priority system (not shown) that gives priority to the operation of the switch 5 over the operation of the shift lever 2, and a part of the shift lever 2 includes a bracket 10 that hangs down from the plate 10. When the operating member 13 is projected to a position where it can be engaged with the pin 12 projecting approximately horizontally from the lower end of the drive range D, and the shift lever 2 is in a range position other than the drive range D, the coil spring 14 serving as a biasing means Only when the shift knobs 6 and 7 of the switch lever 5 are in the recessed position through the insertion holes 8 and 9 of the plate 10, and the shift lever 2 is in the drive range D, the operating member 13 pushes down the pin 12 to 0 moves downward, and the switch knob 6.7 for switching to the 2nd speed or 1st speed is connected to the plate 1.
When the shift lever 2 is in the drive range D, the priority system is configured such that it is exposed through the insertion hole 8.9 of the gear shift lever 6. Press to change the range of the automatic transmission from drive range D to 2nd or 1st range S.
It is designed to switch to F.

Since it has such a configuration, the operation will be explained next.

When the shift lever 2 is rotated to the parking range P, the reverse range R1, and the neutral range N, the operating member 13 is in a relationship that does not push the pin 12, so the plate 10 is moved by the biasing means 14 to the indicator 3. The insertion hole 8 formed in the plate 10 is located close to or in pressure contact with the back surface 3a of the plate 10, and its position is higher than the position of the 2nd speed/1st speed changeover switch Φ knob 6, 7.
9 to 2nd/1st speed switching switch knob 6.7 cannot be operated (Figure 2).

Next, when the shift lever 2 is rotated to the drive range D, the movement of the shift lever 2 causes the operating member 1 to
3 tilts and moves the pin 12 downward, and the plate 10 integrated with the pin 12 moves downward, so the plate 1
The knobs 6.7 of the 2nd speed/1st speed switching switch are exposed through the insertion holes 8 and 9 formed at 0, and it becomes possible to switch between 2nd speed and 1st speed (FIG. 3).

Of course, when the shift lever 2 is rotated to drive range D, neutral range N, reverse range R, and parking range P, it goes without saying that the gear of the automatic transmission changes to each range.

Therefore, when the shift lever 2 is in the drive range D, if you press either the knob 6 or 7 of the shift switch for 2nd or 1st gear, the priority system will change to 2nd or 1st gear S, F.
Since the range can be switched to 2nd speed range S, for example, if you decide that more drive output is required while the vehicle is climbing a slope in drive range D, you can press knob 6 of the changeover switch to 2nd speed range S. This is possible.

At the same time, unless shift lever 2 is set to drive range D, knob 6.7 of the 2nd/1st gear changeover switch cannot be operated, so even if you make a mistake, you will not be able to switch to 2nd/1st range S or F. This prevents children and others from accidentally pressing knob 6 of the switch to switch to 2nd gear range S while rotating shift lever 2 to reverse range R and moving the vehicle backwards. This prevents problems such as the window suddenly moving forward, further increasing safety.

[Effects] As explained above, according to the present invention, as a shift device for an automatic transmission, there is provided a shift lever that is pivotally supported on the vehicle body and that can be switched only to a parking range, a reverse range, a neutral range, and a drive range. and,
an indicator supported by the vehicle body and having an opening formed at a position close to a drive range of the shift lever and covering a base of the shift lever; and an indicator arranged at a position protruding through the opening formed in the indicator. and a switch box which is arranged at a position apart from the back surface of the indicator and has knobs for switching to 2nd speed and 1st speed on the front surface, and a vertically movable switch between the back surface of the indicator and the front surface of the switch box. It consists of a plate that is freely arranged and has an insertion hole formed only in a portion corresponding to the knob of the changeover switch, and a priority system that prioritizes the operation of the switch box over the operation of the shift lever, An operating member is protruded from a portion of the shift lever at a position where it can be engaged with a pin protruding substantially horizontally from the plate, and when the shift lever is in a range position other than the drive range, the operating member is operated by a biasing means. Only when the switch knob of the switch box is in the recessed position from the insertion hole of the plate and the shift lever is in the drive range, the operating member pushes down the pin, and the plate moves downward and the plate moves downward. The knob of the switch for switching to 1st or 1st gear is exposed from the plate, and the priority system is configured to switch to 2nd or 1st gear, respectively, when the shift lever is in the drive range. The automatic transmission is characterized in that when the knob of the switch is pressed, the range of the automatic transmission is changed from the drive range to the 2nd speed or I speed range, so when the shift lever is rotated to the drive range, the shift lever changes. −
The movement of the plate moves the knob of the 2nd/1st gear selector switch to expose the 2nd/1st gear selector switch, allowing the 2nd/1st gear selector switch to be operated. When it is in the drive range, the switch to switch to 2nd and 1st gears cannot be pressed, so when switching to the 2nd and 1st ranges, it is possible to switch to the 2nd and 1st ranges only when the drive range is in the drive range. This is an invention that has a practical effect and is designed to further improve safety.
