[Industrial use]

The present invention relates to a shift stage holding device of a manual transmission of a vehicle, and more particularly, to prevent gears from being randomly pulled out while driving, and to prevent shifting unless the clutch pedal is pressed, so that the child or the driver's side seat A shift gear retaining device is provided to prevent accidental falling of a passenger.

[Prior art]

In general, a manual transmission of a vehicle shifts the position of a shift fork that does not have any force, and prevents the gear from being shifted to neutral while shifting or shifting gears. A shift stage holding device is provided as a means for preventing the falling out.

The prior art of such a shift stage holding device is, as shown in FIG. 4, by digging a semi-circular groove 102 on the shift rail 101 and holding the spring 104 in a state in which a bowl 103 is inserted therein, thereby maintaining the tension of the spring. It is common to be able to determine the position of the shift rail 101.

[Problem to solve]

However, according to the structure described above, there is a problem in that it is not easy to manufacture as well as a sense of shifting by forming its structure inside the complex transmission.

In addition, when the tension of the spring is weakened, it is difficult to maintain the shift stage, thereby implying that there is no reliability.

Therefore, the present invention has been devised to solve the above problems, and the object of the present invention is to prevent the gears from falling out or shifting unless the clutch pedal is stepped, thereby accidentally inducing a child or driver in the driver's side seat. It is intended to provide a shift stage retainer for a vehicle manual transmission to prevent it from falling out.

[Means to solve the problem]

In order to realize this, the present invention includes a reciprocating mechanism including a plate having a plurality of restraint grooves into which a protrusion protruding from the control shaft is inserted into a front surface thereof, and an operating rod connected to the rear side of the plate with a predetermined length;

An anti-rotation mechanism disposed at an outer circumference of the operating rod to prevent the operating rod from rotating and to support the transmission housing;

A bullet member that is tipped between the plate and the anti-rotation mechanism to always advance the plate toward the control shaft;

It provides a shift stage holding device of a manual transmission of a vehicle comprising a connecting member for connecting the rear end of the operating rod and the rotary lever of the clutch cylinder.

Restriction grooves formed in the front of the plate and the select grooves formed in the longitudinal direction in the center; Provides a shift stage holding device of a manual transmission of a vehicle including a circular restraint groove at each shift stage position at which projections of the control shaft are positioned when shifting to both sides of the select long groove.

The anti-rotation mechanism includes a cylindrical member inserted into an outer circumference of the operating rod and having a slide groove formed in an axial direction thereof in a portion thereof; A guide pin protruding from the operating rod and operating in the slide groove; Provided is a shift stage holding device for a vehicle manual transmission comprising a pedestal for fixing the cylindrical member to a transmission housing.

[Action]

In the device of the present invention as described above, when the clutch pedal is pressed for shifting, the reciprocating mechanism is moved to the rear side while the operating rod is pulled, and when the driver shifts in this state, the shift is performed while the control shaft is selected and shifted. After the clutch pedal is released, the reciprocating mechanism is returned to its original position by the elastic restoring force of the elastic member. In the process, the protrusion of the control shaft is inserted into the restraint groove corresponding to the current position.

In this way, if the projection is inserted into the circular restraint groove, since the shift is not made unless the clutch pedal is pressed, the gears are never removed from the driving state.

EXAMPLE

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

1 and 2 are perspective views of the device of the present invention, the device of the present invention is to be able to perform its function while restraining the movement of the control shaft (2) installed at a predetermined position of the manual transmission housing (1).

The control shaft 2 is connected to a shift lever and a cable or a rod installed in the vehicle to perform the select and shift operations simultaneously while performing axial movement and rotational movement.

By restraining such movement of the control shaft 2, it is possible to maintain the current shifted state, and the device of the present invention is installed adjacent to one end of the control shaft 2 as a means thereof.

In other words, the device of the present invention has a predetermined length on the plate 31 and the rear plate 31 formed with a plurality of restraint grooves 30 into which the projection 20 protruding from the control shaft 2 is inserted in the front. A reciprocating mechanism (3) comprising an operating rod (32) connected thereto; An anti-rotation mechanism (4) disposed at an outer circumference of the operating rod (32) to prevent the operating rod (32) from rotating and simultaneously supporting the transmission housing (1); A bullet member (5) which is tipped between the plate (32) and the anti-rotation mechanism (4) so that the plate (31) can always advance toward the control shaft (2); It comprises a connecting member 6 for connecting the rear end of the operating rod 32 and the rotary lever 61 of the clutch cylinder 60.

In the confined groove 30 formed in the front of the plate 3 in the center of the select long groove 33 is formed in the longitudinal direction, the projection of the control shaft (2) when shifting to both sides of the long groove 33 Circular restraint grooves 34 are formed at each shift stage position where the 20 is positioned.

In the above, the opening direction of the circular restraint groove 34 is formed in the same line as the rotation angle of the protrusion 20 so that the protrusion 20 of the control shaft 2 can be smoothly inserted as shown in FIG. It is preferable to form somewhat larger than the outer diameter of).

And the rotation preventing mechanism 4 is a cylindrical member 41 is inserted into the outer periphery of the operating rod 32 and the slide groove 40 is formed in the axial direction on a portion thereof; A guide pin 42 which protrudes from the operating rod 32 and is operated in the slide groove 40; It is made of a pedestal 43 for fixing the cylindrical member 41 to the transmission housing (1).

The guide pin 42 and the slide groove 40 in the above should be formed so that mutual clearance does not occur so that the rotation of the operating rod 32 can be prevented.

In addition, the rotation lever 61 of the clutch cylinder 60 rotates the release shaft 62 in response to the linear reciprocation of the clutch cylinder 60. When the clutch pedal is pressed, the rotation lever 61 is operated by the operation of the clutch cylinder 60. The rotating lever 61 is to be able to pull the connection member (6).

According to the device of the present invention configured as described above, when the clutch pedal is pressed for shifting, the operating rod 32 is pulled by the above operation, and the reciprocating mechanism 3 moves to the rear side as shown in FIG.

In this state, when the driver shifts, the control shaft shifts while selecting and shifting. When the clutch pedal is released after the shift is made, the reciprocating mechanism 3 returns to its original position by the elastic restoring force of the bullet member 5. In this process, the projection 20 of the control shaft 2 is inserted into the restraint groove 34 corresponding to the current position as shown in FIG.

When the projection 20 is inserted into the circular restraint groove 34 as described above, since the shift is not performed unless the clutch pedal is pressed, the gear is not removed at all in the running state.

[effect]

As described above, the present invention does not allow the shifting to be performed unless the clutch pedal is pressed by a simple configuration, so that the gear is not operated by operating the shift lever inadvertently by the passenger or by operating the shift lever with a joke. It is a useful design that can prevent accidents that may occur while falling out.
