Description

6-speed manual transmission shift rail support

The present invention relates to a six-speed manual transmission operating mechanism, and more particularly, to a six-speed manual transmission shift rail support device that prevents misoperation during 2/4 and 3 / 5-speed shifts.

In general, the manual transmission has a transmission operating mechanism that transmits the driver's shift lever operating force to the transmission's synchronizer.

The transmission operating mechanism is configured in various ways according to the type of the transmission and the number of gear stages. The direct operation method and the remote operation method are applied according to the distance between the shift lever and the shift period, and the remote operation method is frequently used.

The transmission operating mechanism adopting this remote operation method is to transmit the operating force of the shift lever to the cable and to the rod, which will be described as using a rod. Thus, the transmission operating mechanism is connected to the shift rod and the select rod to transmit the operating force of the shift lever to the shift rail where each speed fork is installed.

The shift rail is composed of three or four gears according to the type of shift stage, and the six-speed manual transmission includes 1 / R, 2/3, 4/5, and six shift gears.

These 1 / R, 2/3, 4/5, six-stage shift rails 51, 53, 55, 57 are supported by a support device as shown in FIG.

That is, 1 / R, 2/3, 4/5, and 6-speed shift rails 51, 53, 55 and 57 are adjacent to each other when the steel balls 59, 61 and 63 are interposed therebetween, In order to prevent the gear shift stage from being selected, the interlock pins 65 and 67 installed in the 2/3 and 4/5 stage shift rails 53 and 55 and the respective stage shift rails 51, 53, 55 and 57 are respectively. It is supported by the gear shift lower case 85 by other interlock pins 77, 79, 81, 83, etc. via springs 69, 71, 73, 75 of the straight line. And shifting while rotating.

However, since the shift lever is operated in accordance with the transmission shift pattern as shown in FIG. 1, the shift rail of a specific shift stage is selected and shifted and selected to operate. It is difficult to reduce the engine overrun due to an incorrect operation of the shift lever in the 3, 4/5 step region, and the possibility of body vibration and accidents caused by the overrun.

Therefore, the present invention has been made to solve the above disadvantages, the object of the present invention is to prevent the misoperation of the shift lever in the 2/3, 4/5 stage region by the engine overrun and body vibration caused by this And a six-speed manual transmission shift rail support device for reducing the possibility of an accident.

BEST MODE Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a simplified diagram of a transmission gear shift pattern to which a six-speed manual transmission shift rail support device according to the present invention is applied, and selects the shift lever 1 1 / R, 2/3, 4/5, and 6 steps. It is configured to be.

When the shift lever 1 is operated according to the transmission gear shift pattern formed as described above, 1 / R, 2/3, 4/5, 6 through a transmission operating mechanism (not shown) connected to the shift lever 1. However, the shift rails 3, 5, 7, and 9 are shifted and selected to control the selected synchronizer (not shown) to realize shifting.

These 1 / R, 2/3, 4/5, and 6-stage shift rails 3, 5, 7, and 9 are supported by the shift lower case 11 by a shift rail support device as shown in FIG. .

That is, between the 1 / R, 2/3, 4/5, and 6-speed shift rails 3, 5, 7, and 9, the first, second, and third steel balls 13 are provided for smooth operation and transmission theft between them. , 15, 17).

First and second interlock pins are provided on each of the 1 / R, 2/3, 4/5, and 6-speed shift rails 3, 5, 7, and 9 so as to prevent adjacent gears from being selected when a specific gear is selected. (19, 21) is interposed.

The first interlock pin 19 is penetrated to the 2/3 and 4/5 step shift rails 5 and 7, respectively, and the second interlock pin 21 is provided to the first, second, third and fourth springs 23. Are provided to support the first / R, 2/3, 4/5, and six-stage shift rails 3, 5, 7, and 9, respectively, by the elastic force of .25, 27, 28.

In addition, the 6-speed manual transmission shift rail support device prevents 4/5 shifts when shifting 2/3 by the shift lever 1 and prevents 2/3 shifts when shifting 4/5 respectively. The 2/3 and 4/5 step shift rail operating force increasing means which is comprised so that interaction with the 5 step shift rails 5 and 7 can be provided is provided.

The 2/3, 4 / 5-stage shift rail operating force increasing means may be configured by various principles, but in this embodiment, any one of the 2/3, 4 / 5-stage shift rails 5,7 is selected. If so, the operating operation force of the other shift rail is increased to prevent erroneous operation.

Therefore, the 2/3, 4/5 step shift rail operating force increasing means allows the second and third springs 25, 27 supporting the 2/3, 4/5 step shift rails 5, 7 to interact with each other. It consists of a rocker arm 31.

The rocker arm 31 supports one end of each of the second and third springs 25 and 27 at both ends thereof, and is mounted on one side of the lower shift case 11 with a rotatable hinge.

In order for the rocker arm 31 to smoothly interact with the second and third springs 25 and 27, the first and second spring sheets may be disposed between the tip of the rocker arm 31 and the second and third springs 25 and 27. 33 and 35 are respectively interposed.

When the two-third stage is selected by the shift lever 1 of the vehicle provided with the six-speed manual transmission shift rail supporting device configured as described above, the two-third stage shift rail 5 is shifted by two-thirds. In this case, the two- or three-stage select operation is activated to activate the synchronization unit of the selected shift stage.

As such, when one shift stage of the two-third stage is selected by the shift lever 1, the two-third shift rail 5 is operated to support the second shift pin supporting one of the second interlock pins 21. The ring 25 exerts a stronger elastic force on the rocker arm 31 than when the shift stage is not selected.

Accordingly, while the third spring 27 positioned on the other side of the rocker arm 31 is compressed, the second interlock pin 21 positioned thereon exerts a strong elastic force on the 4 / 5-stage shift rail 7. . That is, the third spring 27 presses the 4 / 5-stage shift rail 7 together with the elastic force increased in the second spring 25.

As a result, the six-speed manual transmission shift rail support device greatly increases the operating maneuverability of the four-fifth shift rail 7 that selects the four-fifth shift stage when the two-third shift stage is selected. To prevent malfunction.

On the other hand, when the shift lever 1 selects one shift stage of 4/5, the 4/5 shift rail 7 is operated to support a third spring supporting one of the second interlock pins 21. (27) exerts a stronger elastic force on the rocker arm 31 than when this shift stage is not selected.

Accordingly, while the second spring 25 located on the other side of the rocker arm 31 is compressed, the second interlock pin 21 positioned thereon exerts a strong elastic force on the 2/3 step shift rail 5. . That is, the second spring 25 presses the 2/3 step shift rail 5 together with the elastic force increased in the third spring 27.

As a result, the six-speed manual transmission shift rail support device greatly increases the operating maneuverability of the two-third shift rail 5, which allows the two-third shift stage to be selected when the four-speed shift stage is selected. To prevent malfunction.

When the second and third springs 25 and 27 are interoperable, the elastic force of the second and third springs 25 and 27 may smoothly act on the rocker arm 33. The first and second springs 25 and 27 are supported.

As described above, the six-speed manual transmission shift rail support device according to the present invention has a 2/3, 4 / 5-stage shift rail operating force increasing means configured to interact with the 2/3, 4 / 5-stage shift rail to operate the shift lever. Therefore, it is possible to increase the operating force of 4/5 shifts at 2/3 shifts and to increase the operation force of 2/3 shifts at 4/5 shifts, thereby preventing engine overrun due to shift lever misoperation.

Therefore, the present invention can reduce the vehicle body vibration and the possibility of accident due to the engine overrun.
