Description

Shift lever operation mechanism of the vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to transmission of a vehicle, and more particularly to a shift lever control mechanism of the manual transmission for a vehicle.

The transmission of the vehicle is installed between the engine clutch and the propulsion shaft or the engine clutch and the longitudinal reduction gear device, and is used to increase the rotational force or to change the high speed by appropriately shifting the engine rotation to suit the driving condition of the vehicle. It also serves to leave the engine idle and back up the car.

The shift lever provided in the cabin is used to operate the gear mechanism of the transmission by transmitting the operating force of the lever to the transmission. When the shift lever is operated, the stage of the shift lug is selected by the control shaft and the control finger, and the shift rail is moved as the stage of the shift lug is selected. As the shift rail moves, a shift fork fixed to an end of the shift rail performs a shift operation on the transmission synchronizer mechanism.

Referring to Fig. 1, there is shown a plan view schematically showing a shift lever operating structure according to the prior art, and the shift lever operating mechanism 10 of seven shifts includes four shift rails 12, 12a, 12b, and 12c. Although two lugs 14, 14a, 14b, 14c and only one shift fork 16c are shown in the figure, the number of forks is equal to the number of lugs 14, 14a, 14b, 14c.

The respective lugs 14, 14a, 14b, 14c are mounted at the ends of the respective shift rails 12, 12a, 12b, 12c so as to focus on the fingers provided at the bottom of the shift lever, although not shown in the figure. It is positioned and easily connected to the finger, the shift fork 16c is mounted to be spaced apart from each other on a portion of the shift rail (12c) to move the sleeve in accordance with the movement of the rail (12c) to drive the transmission gear Gear shifting is achieved by engaging the gears.

In the prior art as described above, a typical five-speed transmission consists of three shift rails, three lugs and three shift forks, and a seven-speed transmission consists of four shift rails, four lugs and four shift forks. The size of the transmission is enormous and the weight is increased so that the output of the vehicle is not only lowered, but also a problem arises in that the transmission design is accompanied by difficulties.

Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to provide a shift lever operating mechanism composed of a plurality of shift rails and lugs, in which an arbitrary shift fork and a lug are integrally formed so that the other The present invention provides a shift lever operating mechanism in which a cost is reduced without output deterioration even in a vehicle having multiple speeds by being mounted on a shift frame.

With the shift lever operating mechanism of the vehicle according to the present invention, the above object is easily achieved, and, in accordance with an aspect of the present invention, a lug whose end is selected by a finger mounted on the lower end of the shift lever; A shift rail moved in operation of the shift lever due to engagement with the selected lug; And a shift lever operating mechanism mounted on a portion of the shift rail and configured as a shift fork for moving the gear in the axial direction by operation of the shift rail, wherein a shift fork and a lug of one of the plurality of shift forks are integrally manufactured. In the integrated shift port, another adjacent shift stage shift rail is inserted into and coupled to a bearing in a press-fitted state.

According to the above characteristics of the present invention, the lug installed in the other stage is a structure in which four stages are formed on one shift rail as a result of shifting the shift fork by shifting the shift fork directly without moving the shift rail.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

FIG. 2 is a schematic plan view of a shift lever operating mechanism of a vehicle according to the present invention, and FIG. 3 is a cross-sectional view taken along the line A-A of FIG.

The seven-shift shift lever operating mechanism 30 has three shift rails 32, 32a, 32b, four lugs 34, 34a, 34b, 34c, and only one shift fork 36c in the painting. The number of forks equal to the number of lugs 34, 34a, 34b, and 35c.

The three lugs 34, 34a and 34b except the one lug 34c are mounted at the ends of the three shift rails 32, 32a and 32b, and the three shift rails 32, 32a and 32b. A shift fork is installed at a certain portion of the). In addition, the one lug 34c is integrally formed with the shift fork 36c and then installed on another shift stage shift rail 32b adjacent to each other, and between the shift fork 36c and the shift rail 32b. The bearing 38 is interposed.

In the present embodiment, only one shift rail is deleted in the case of the seven-speed shift, but two shift rails can also be deleted, and it is also applicable in the case of five-speed shift.

When the operation by the above configuration of the present invention, the first, second, third, fourth and fifth speed, the reverse is the same as the operation of the shift lever operating mechanism according to the prior art, but in the case of 6,7 When the finger engages and engages the lug 34c, the lug 34c is directly actuated on the shift fork 36c integrally formed with the lug 34c, thereby allowing the fork 36c on the adjacent shift rail 32b. ) Is shifted, so the sleeve shifts gears by engaging the transmission gears with the spindle drive gear.

According to the above configuration and operation of the present invention, the transmission can be made light in weight even in a multi-speed vehicle, and the output reduction is prevented, the transmission design is easy, and the shift rail can be eliminated, thereby reducing the cost. have.

While the invention has been shown and described with reference to certain preferred embodiments, it will be understood that the invention can be modified and modified in various ways without departing from the spirit or scope of the invention as set forth in the following claims. Those skilled in the art can easily know that.
