Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail.

[0027] The present invention provides a selection system 14 of an automatic transmission, such as Figure 1 to Figure 6 As shown, it mainly includes a selection lever 15, a lower casing 16, an upper casing 17 and a connecting rod member 18, etc., by turning the selection lever 15 toward the left and right direction ( figure 1 The center is the vertical direction of the paper) to switch between the A / T mode of mechanical positioning and the manual mode of electric positioning. The lower case 16, which is a mounting part of the selector lever 15, is formed in a box shape with an upper side open, and is equipped with a link member 18, a shift lock mechanism 19 during selection, and an accent mechanism 20 as will be described in detail later. , Misoperation prevention mechanism, etc. Installed on the upper opening of the lower case 16, and on the upper case 17 and the indicator 21 as a cover, there are var...

Abstract

Provided is a selection system for an automatic transmission in which a speed change position is not eliminated and the automatic transmission is not speed change-controlled to other speed change position by an external factor such as road surface impact and a small stone jumped up or an internal factor such as an engagement form of a selection lever and a link member regardless of an A / T mode and a manual mode. In the selection system for an automatic transmission, a mechanical automatic mode and an electric manual mode are switched by the selection lever. The selection system is provided with a selection lever extension engagement part; and the link member to which the extension engagement part is always inserted. The link member is turned accompanying with a lever operation of the selection lever to mechanically speed change-control the automatic transmission when the selection lever is in the A / T mode. When the selection lever is in the manual mode, the turning for mechanically speed change-controlling the automatic transmission is restricted by the extension engagement part.

Description

technical field [0001] The invention relates to a selection system of an automatic transmission. Background technique [0002] Such as Figure 7 , Figure 8 As shown, the selection system (hereinafter referred to as the selection system) 1 of the automatic transmission in the prior art moves the selection lever 2 to the left and right to switch between the A / T mode (automatic transmission mode) 3 and the manual mode (manual transmission mode). mode)4. Usually, under the structure of this selection system 1, when the selection lever 2 is shifted to the A / T mode 3, the lever operation accompanied by the selection lever 2 will generate a buckling operation of the link part 5, and through the end part 6 The selector cable (not shown) connected to the inhibit (range) switch of the automatic transmission is exported and introduced to perform automatic shift control of the automatic transmission, and at the same time, the selector lever shifted to the D range position of A / T mode...
