Description

Gear shift and select 4/5 stage neutral position device of manual transmission in vehicle}

The present invention relates to a vehicle manual transmission, and more particularly to a gear select 4/5 stage neutral setting device of a vehicle manual transmission.

In general, transmission shifting is performed in a neutral position, so the select neutral setting function and action are important to prevent a driver's miss shifting.

This select neutral setting function is generally provided using a spring acting on each shift stage.

For example, in the case of a six-speed manual transmission, a select neutral setting is implemented by combining a retainer and a return spring on the torsion shaft, which is coupled to a sliding lever for selecting and maintains rotational freedom. It acts to constrain the degree of freedom.

However, this neutral setting method has a disadvantage that is greatly affected by the tension of the return spring. For example, when the tension of the 2/3 stage return spring is large, the neutral setting is pushed toward the 6th stage when setting the 4/5 stage neutral. There is a disadvantage that the position may be changed.

In addition, when the return spring is shaken due to repeated pressing of the 2 / 3-speed return spring according to the 2 / 3-speed shift, there is a disadvantage in that the selection function may be lost due to the weakening of the return spring mounting.

 In addition, in the case where the play occurs in the 2/3 stage and the 4/5 stage, there is a big disadvantage that the driver's miss shifting phenomenon may occur.

The present invention has been devised in view of the above-mentioned point, and the 2 / 3-stage retainer is seated through the case part, and the structure supporting the 2 / 3-stage return spring is applied to the 2 / 3-stage return spring. It can be pushed to the 6th stage with high tension to prevent the 4 / 5th stage neutral position from shifting, and it is possible to completely prevent the loss of the selection function by stabilizing the mountability of the 2 / 3-speed return spring even when repeatedly pressed. It is an object of the present invention to provide a neutral setting device of a speed manual transmission.

In addition, the present invention is intended to block the phenomenon of theft reduction when the neutral restoration at the sixth stage, as the two-third-stage retainer supporting the 2 / 3-stage return spring is seated through the case portion.

The present invention for achieving the above object, the gear shift select 4 / 5-stage neutral setting device of the manual transmission

A two-third stage return spring installed to the right side of the sliding lever with a sliding lever splined to the torsion shaft fixed to the transmission case by a spring pin;

2 / 3-stage retainers which support the left-hand side of the 2 / 3-stage return springs;

A seating end extending to an inner wall surface of the right space of the case so that the two-third-stage retainers are closely supported;

Characterized in that configured to include.

The two-third-stage retainer forms an upper end of the base end coupled toward the torsion shaft, and is in close contact with the seating end of the case, and constitutes an upper end that elastically supports the two-thirds return spring.

According to the present invention, since the 2 / 3-stage retainer is supported through the case portion, there is an effect of preventing the reduction of the sense of theft restored to the neutral in 6th stage, and the 2 / 3-stage retainer seated on the case portion is 2/3. Since the stage return spring is elastically supported, it has an effect of preventing the phenomenon that the 4/5 stage neutral position can be changed by being pushed toward 6 stages by the large tension of the 2/3 stage return spring.

In addition, the present invention, since the mounting performance of the 2 / 3-stage return spring is stabilized even when repeated pressing by the shift operation, there is an effect that completely blocks the possibility of loss of the selection function.
