Abstract

PURPOSE:To enhance the safety by furnishing a shift lever for changeover into P, R, N, D range and a switch box to perform changeover to the 2nd or 1st speed position, wherein the changeover into the 2nd or 1st speed position can be made only when the shift lever lies in the D range. CONSTITUTION:When a shift lever 3 is moved into the D range, rotation of the lever 3 nullifies the tensile force applied to the tail 13b of a changeover cable 13, so that a spring 29 exposes a 2nd position and a 1st position selector switch 21, 23 of a switch box 9 from an opening formed in an instrument panel 1. When it is judged under running in the D range to need further drive output for ex. on a slope, the necessary power is generated for ex. by pushing the selector switch 21 for the 2nd range. If the shift lever 3 is operated into the N, R, P ranges, switch box 9 is retracted in the instrument panel 1 by the cable 13 against the action of the spring 29, which puts the switches 21, 23 into out of operability.

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 prior art, 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 set the drive range to drive while driving at high speed. For example, there is a risk of pressing the switch for the barking range. 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 there is a desire to improve this problem.

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 including 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; a switch box that is biased in the protruding direction through a formed opening and has switch switches for switching to 2nd speed and 1st speed arranged on its surface; and a switch box that gives priority to the operation of the switch box over the operation of the shift lever. The other end of the switching cable, one end of which is supported by the shift lever, is supported on the back of the switch box, and when the shift lever is in a range position other than the drive range, the switching cable is connected to the switch box. The priority system is located inside the vehicle body against force, and is configured such that the switch for switching to the second gear or the first gear is exposed from the vehicle body only when the shift lever is in the drive range. The automatic transmission is characterized in that when the shift lever is in the drive range and the switching switch to the 2nd speed or 1st speed range is pressed, the range of the automatic transmission is changed from the drive range to the 2nd speed or 1st speed range. It is something to do.

[For production]

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

Said shift train. When the bar is rotated into the drive range, the switching cable is moved by the movement of the shift lever, and the switch box is pushed out from the vehicle body by the means that urges the switch box in the protruding direction, exposing the 2nd/1st gear selector switch. , the 2nd speed/1st gear selector switch can be operated.

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 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 switching between 2nd and 1st gears cannot be operated.
Even if you make a mistake, you will not be able to switch to the 2nd or 1st speed range.

The trans connection cable 19 is connected.

The switch box 9 has switch switches 21 . to 2nd speed S and 1st speed F, respectively. 23 is disposed on the surface thereof, and an edge 27 of the opening 1l of the instrument panel l, which protrudes vertically in a flange shape at a position lower than the exposed part 25. The base portion 3l is configured to be biased in a direction in which the exposed portion 25 projects from the opening l1 of the instrument panel 1 by a spring 29 serving as a biasing means.

The switching cable l3 has one end 13a arranged in parallel with the transmission cable 19 connected to the lower part 3a of the console box 5 of the shift lever 3, and the other end 13b connected to the switch box 9. It is supported by the back surface of the exposed portion 25, and when the range of the shift lever 3 is in the drive range D, the other end 13b of the cable l3 is not pulled, and the shift lever 3 is in the neutral range N1, the reverse range R, and the parking range P.
As the shift operation is performed, the switch box 9 is biased against the tensile force of the spring 29 so that it sinks into the instrument panel 1 (toward the right in FIG. 2). Code 33 is the cable 1

is in drive range D, the 2nd gear S or 1st gear F
When the respective changeover switches 21 and 23 are pressed, the range of the automatic transmission (not shown) changes from drive range D to 2nd gear range S or 1st gear range F even though the shift lever is in drive range D. It is controlled to switch preferentially to

With this configuration, the shift lever 3 is moved to the drive range D.
When the shift lever 3 is rotated, the pulling force on the switching cable l3 disappears, so the switch box 9 is moved from the opening l1 of the instrument panel l by the spring 29 to the 2nd gear S-1st gear of the exposed part 25. F changeover switch 21. 23 is exposed, and the switch 21 . Since only the operation 23 is possible, if it is determined that more drive output is required while the vehicle is climbing a slope in drive range D, for example, the changeover switch 21 to 2nd speed range S can be pressed. , while the shift lever 3 is rotated to the reverse range R and the vehicle is moving backwards, a child or the like accidentally presses the changeover switch 21 to the 2nd gear range S, so the vehicle suddenly moves forward suddenly. This means that there will be no problems that could result in storage, further increasing safety.

In addition, the code 39. 41, 43. 45, the shift lever 3 is in the parking range P1 reverse range R

[Effects] As explained above, according to the present invention, the shift device for an automatic transmission includes 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,
a switch box which is biased in a protruding direction through an opening formed in the vehicle body and has a changeover switch for 2nd speed and 1st speed on its surface; and an operation of the switch box in response to the operation of the shift lever. This is a priority system that gives priority to the shift lever, and the other end of the switching cable is supported on the back side of the switch box, one end of which is supported by the shift lever, and the shift lever is in a range position other than the drive range. Sometimes, the switching switch is located inside the vehicle body against the biasing force, and is configured such that the switch for switching to the second gear or the first gear is exposed from the vehicle body only when the shift lever is in the drive range, The system is configured such that when the shift lever is in the drive range and the switch to switch to the 2nd or 1st gear range is pressed, the range of the automatic transmission is switched from the drive range to the 2nd gear or 1st gear range. Therefore, when the shift lever is rotated to the drive range, the switch box moves due to the movement of the shift lever, exposing only the 2nd and 1st gear selector switches, and the switch for 2nd and 1st gears is exposed. It becomes possible to operate the changeover switch, and when the shift lever is in the parking range, reverse range, or neutral range, the changeover switch to 2nd and 1st gear ranges cannot be pressed, so it is not possible to press the changeover switch to 2nd and 1st gear ranges. When switching, it is possible to switch to the 2nd speed and 1st speed ranges only when the gear is in the drive range, and this invention has a practical effect in consideration of further increasing safety.
