Description

The present invention relates to a selector lever locking device for an automobile, and more specifically, in order to prevent theft of the automobile, in the case of an automobile equipped with an automatic traveling transmission mechanism, the selector lever is locked at a parking position, and a manual traveling transmission mechanism is provided. The present invention relates to a selector lever locking device for a vehicle provided with a mechanism for locking the selector lever at a reverse or neutral position.

Most of the recent passenger cars are equipped with an automatic traveling speed change mechanism. In this device, the selector (shift) lever is set to P (parking), R (reverse), N (neutral), D (drive), L (low). The operation method of moving to a desired position in each range arranged in order is adopted, and the operation is simple and easy. When the vehicle is parked and the selector lever is moved to the position of the P range, the parking lock mechanism locks the rotation of the output shaft so that the parked vehicle does not move inadvertently together with the side brake. .

  Further, in order to facilitate the meshing of the gears at the time of shifting, the automatic traveling speed change mechanism is provided with two blades in front and rear with oil sandwiched in place of the clutch plate in the power transmission path. The fuel consumption is inferior to the traveling speed change mechanism. For this reason, many large vehicles such as trucks where fuel economy is important are equipped with a manual traveling speed change mechanism.

  The shift position by the selector lever of the manual traveling speed change mechanism includes the forward 1, 2, 3, and 4 stages, N (neutral), and R (reverse). There is also a thing. In such a manual traveling speed change mechanism, when the selector lever is operated to each forward stage and the R position, the N position is always passed in the middle. During parking, the selector lever is often moved to the R position. When there is a possibility that the automobile moves backward on a slope, the selector lever is moved to the forward position.

In vehicles equipped with the manual travel speed change mechanism, there is no special position for the selector lever for parking, but for cars equipped with an automatic travel speed change mechanism, a position dedicated for parking is provided, and the selector lever is set to this position. A parking lock mechanism is installed that keeps the brake applied to ensure safety when the vehicle is positioned so that the vehicle does not move carelessly.

Conventionally, this parking lock mechanism has several structures. Examples of the structure include an automatic transmission for a vehicle described in Patent Document 1, a selector lever device for a vehicle described in Patent Document 2, and the like. It is known.

The automatic transmission for an automobile includes, for example, a select lever capable of manually selecting a travel range including reverse and parking, a manual valve connected to the select lever and capable of generating reverse hydraulic pressure at a reverse range position, and the reverse hydraulic pressure And an oil pressure control valve for engaging a predetermined fastening element of the speed change mechanism, and a parking lock mechanism that is connected to the select lever and that operates to lock the output shaft when a parking range is selected. The automatic transmission includes an interlock mechanism that engages another fastening element in addition to a predetermined fastening element that is engaged based on the reverse hydraulic pressure when the parking range is selected. Park the car and move the select lever to the P range position Are those nail fixed gears on the output shaft is configured to lock the rotation of the output shaft engages (see Patent Document 1).

  On the other hand, when the selector lever device for a vehicle is in the parking position, the lock pin operates when the power-on key of the vehicle, which is the engine key, is OFF. Some have a mechanism for locking the selector lever (see Patent Document 2).
