Abstract

PURPOSE:To enable switch-over to a 1st and a 2nd forward speed range to be made only when in a drive range, and also enable switch-over to a parking and a reverse range to be made only when in a natural range by covering a switch box while being interlocked with a shift lever. CONSTITUTION:Switch-over switches 15 and 17 to switch-over to a reverse range R and a packing range P are interposed at the upper section of a switch box 7, in addition, switch-over switches 19 and 21 to 2nd forward speed S and 1st forward speed F are also interposed to the lower section of the box. One end section 25 of a cover 9 is rotatably supported 23 onto an instrument panel, and is concurrently supported rotatably onto a bar 27 projecting outward from a shift lever 1 in such a way that the other end section 29 is controlled to be rotated upward while only the switch-over switches 15 and 17 to the reverse range R and the parking range P are covered when the shift lever 1 is in a drive range D, and is also controlled to cover only the switch-over switches 19 and 21 to 2nd forward speed S and 1st forward speed F when the shift lever 1 is in a neutral range N.

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 Invention] A conventional shift device for an automatic transmission used, for example, in the floor of an automobile, is disclosed in, for example, Japanese Utility Model Application No. 131425/1983.

However, according to this conventional technology, since the system uses a button switch to switch between the parking range, reverse range, neutral range, drive range, 2nd speed and 1st speed range, it is possible to accidentally park the car in the drive range while driving at high speed. There is a risk of pressing the range or reverse range switch. Furthermore, there is a risk that the 2nd or 1st gear range switch may be pressed by mistake while the vehicle is moving backwards in the reverse range, so there is a desire to improve this problem.

Therefore, according to the present invention, in view of such conventional problems, two
When switching to 1st and 1st speed ranges, switching to 2nd and 1st ranges is possible only when in drive range, and when switching to parking range and reverse range, switching to 2nd and 1st ranges is only possible when in neutral range. The purpose is to enable switching to reverse 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 the vehicle body and that can switch only between a drive range and a neutral range, and a shift lever that is provided at the top to switch to a reverse range and a parking range, respectively. A switch box in which a switch is arranged and a changeover switch for 2nd speed and 1st speed is arranged at the bottom, and a switch box rotatably supported on the vehicle body, with one end supported by the shift lever and the other end supported by the shift lever. - a cover formed to cover only the changeover switches to the reverse range and the parking range when the shift lever is in the drive range, and to cover only the changeover switches to the 2nd speed and 1st speed when the shift lever is in the neutral range; When the shift lever is in the drive range, when the switch to switch to 2nd gear or 1st gear is pressed, the range of the automatic transmission is switched from the drive range to the 2nd gear or 1st gear range, and the shift lever is pressed.
The automatic transmission is characterized by having a priority system in which the range of the automatic transmission is switched from the neutral range to the reverse range or the parking range when the switching switch to the reverse range or the parking range is pressed when the automatic transmission is in the neutral 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 drive range,
The cover rotates with the movement of the shift lever, shifting between 2nd and 1st gears.
Only the speed changeover switch is exposed, and the 2nd speed and 1st speed changeover switches can be operated.

Furthermore, when the shift lever is rotated to the neutral range, the cover rotates due to the movement of the shift lever, exposing only the reverse range and parking range selector switches, and the operation of the reverse range and parking range selector switches is not possible. becomes possible.

Therefore, while the shift lever is in the drive range,
By pressing either the 2nd or 1st speed selector switch, the range can be switched to 2nd or 1st speed using a priority system.

At the same time, unless the shift lever is in the drive range, the switch for 2nd and 1st gear cannot be operated.
Even if you make a mistake, you will not be able to switch to the 2nd or 1st speed range.

Furthermore, when the shift lever is in the neutral range, if either the reverse range or the parking range switch is pressed, the priority system allows the range to be switched to reverse or parking.

At the same time, unless the shift lever is in the neutral range, the reverse or parking switch cannot be operated, so even if the shift lever is not in the neutral range, the reverse or parking range cannot be changed.

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

1 and 2 are views showing an embodiment of the present invention, and reference numeral 1 designates a shift lever 5 that is pivotally supported on an instrument panel 3 that is a vehicle body so as to be rotatable up and down. Reference numeral 7 is a switch box fixed to the instrument panel 3. Reference numeral 9 is a cover.

The shift lever 1 is movable up and down through a long hole 11 formed on the surface of the instrument panel 3, and has an operation knob 13 on a portion protruding from the surface of the instrument panel 3. On the rear side 1a of the shift lever 1, when the operation knob 13 of the shift lever 1 is operated downward, the range of the automatic transmission (not shown) is switched to drive range D, and when the operation knob 13 of the shift lever 1 is operated upward. The range of the automatic transmission (not shown) is switched to the neutral range N when the automatic transmission (not shown) is operated.

The switch box 7 is disposed on the surface of the instrument panel 3, and has switch switches 15, 1 for switching to reverse range R and parking range P, respectively, at the top.
7 is disposed, and switches 19 and 21 for switching to second speed S and first speed F are disposed at the bottom.

The cover 9 has one end 25 and the other end 29 formed in an abbreviated shape, and the one end 25 is rotatably supported 23 on the instrument panel 3 and laterally from the shift lever 1. The other end 2 is pivotally supported by a bar 27 protruding from the
When the shift lever 1 is in the drive range D, as shown in FIG. When 1 is in neutral range N, 2nd gear and 1
It is assembled so as to be controlled to rotate downward so as to cover only the speed S and F changeover switches 19 and 21, respectively.

Each switch 15, 1 of the shift lever 1 and the switch box 7? , 19 and 21 is controlled by a priority system. The priority system is configured such that when the shift lever 1 is in the drive range D, the priority system
Changeover switches 19 and 2 to speed S or 1st speed F, respectively
When 1 is pressed, the range of the automatic transmission (not shown) is switched preferentially from drive range D to 2nd gear S or 1st gear F, even though shift lever 1 is in drive range D. -1 is in the neutral range N, and when the switches 15 and 17 to reverse range R or parking range P are pressed, the range of the automatic transmission (not shown) changes to shift lever -1.
Even though the range N is the neutral range N, the control is such that the neutral range N is preferentially switched to the reverse range R or the parking range P.

With this configuration, when the shift lever 1 is rotated to the neutral range N, the changeover switches 17 and 15 for the parking range P and reverse range R are exposed, but the switches 17 and 15 for the parking range P and reverse range R are exposed, but the switches 17 and 15 are exposed for the 2nd gear range S and 1st gear range F. Since the changeover switches 19 and 21 for 2nd and 1st speeds are covered by the other end 29 of the cover 9, it is impossible to operate the 2nd and 1st speed changeover switches 19 and 21, for example, when switching to reverse range R. This means that there will be no problem such as a child accidentally switching to 2nd gear or 1st gear range S or F while the vehicle is moving backwards by pressing the switch 15. This will further improve safety. It will increase.

Then, in the same way, move shift lever 1 to drive range D.
When the shift lever 1 rotates, the other end 29 of the cover 9 rotates to shift to 2nd gear S.

The changeover switches 19 and 21 for 1st speed F are exposed, and only the switches 19 and 21 can be operated, and the changeover switch for parking range P1 and reverse range R is switched on: y
-15, 17 are covered by the other end 29 of the cover 9, so it is impossible to operate the changeover switches 17, 15 for the parking range P1 reverse range R, for example, switching to the 2nd speed range S. This prevents problems such as a child or the like accidentally pressing the reverse range R switch 15 while the vehicle is climbing a slope by pressing the switch 19, resulting in a malfunction of the automatic transmission (not shown). Therefore, safety will further increase.

Note that numerals 31 and 33 are symbols written on the surface of the instrument panel 3 to indicate that the shift lever 1 is in the neutral range N and drive range D. Further, the reference numeral 35 is a steering wheel.

〔effect〕

As explained above, according to the present invention, the shift device of the automatic transmission includes a shift lever that is pivotally supported on the vehicle body and that can switch only the drive range and neutral range, and a shift lever that is mounted on the upper part to switch between the reverse range and the parking range. a switch box in which a changeover switch is disposed, and a changeover switch for 2nd speed and 1st speed is arranged at the bottom; When the shift lever is in the drive range, it covers only the reverse range and parking range switches, and when the shift lever is in the neutral range, it covers only the second and first gear switches. When the cover and the shift lever are in the drive range, when the switch to switch to 2nd or 1st gear is pressed, the range of the automatic transmission is switched from the drive range to the 2nd or 1st gear range, and the shift lever is in the drive range. The automatic transmission is characterized by having a priority system that switches the range of the automatic transmission from the neutral range to the reverse range or the parking range when the switching switch to the reverse range or the parking range is pressed when the automatic transmission is in the neutral range.
When the shift lever is rotated to the drive range,
The cover rotates with the movement of the shift lever, shifting to 2nd gear.
Only the speed selector switch is exposed, allowing the 2nd and 1st gear selector switches to be operated. Also, when the shift lever is rotated to the neutral range, the cover rotates due to the movement of the shift lever, allowing the switch to switch to reverse and reverse ranges. Only the changeover switches for each parking range are exposed, and the changeover switches for reverse range and parking range can be operated, so when switching to 2nd and 1st speeds, only when changing to drive range.
In addition to making it possible to switch to the 1st and 1st speed ranges, it is also possible to switch to the parking range and reverse range only when the neutral range is in the neutral range, making it safer. This is an invention that has a practical effect and is designed to further enhance the quality of the invention.
