Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual transmission for an automobile in which a shift cable is locked at one end and an outer lever that swings around the axis of a shift and select shaft moves in the axial direction of the shift and select shaft. Shift device.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for manual transmissions to improve the shift feeling, and particularly the peak load during shift operation deteriorates the shift feeling as "rigid feeling" or "stuck feeling". I know.

Therefore, conventionally, a method has been used in which a weight is added to the inside of the shift knob or around the control shaft to reduce the peak load due to its inertia and obtain a smooth shift feeling.

That is, in the first conventional shift device for a manual transmission for an automobile, a shift cable C is locked at one end as shown in FIG.
The inertial mass M is disposed directly on the other end of the outer lever L that swings around the center of the center, and the inertial mass of the inertial mass M reduces the peak load to obtain a smooth shift feeling.

Further, in the second conventional shift device for a manual transmission for an automobile, as shown in FIG. 12, an outer lever L swinging around a shift and select shaft S with a shift cable C locked at one end. On the other hand, the interlocking inertia lever IL in which the inertia mass M is arranged is arranged in parallel.

[0006]

SUMMARY OF THE INVENTION The above-mentioned first conventional shift device for a manual transmission for an automobile is provided with the outer lever L.
Since the inertial mass (additional mass) M is directly attached on top, there is a problem that the effect of the inertial mass M is small.

Even if the inertial mass M having the same mass is attached to the outer lever L, the inertial effect (equivalent mass) transmitted on the cable C is small, and in order to obtain the necessary inertial effect, the inertial mass M is required. There was a problem that a large trout was needed.

Since the inertial mass M is mounted on the shift and select shaft S, there is a problem that not only the shift operation requiring the inertial effect but also the select operation is affected.

Further, in the above-mentioned second conventional shift device for a manual transmission for an automobile, the outer lever L and the inertia lever I are used.
Since L and L are arranged in parallel with each other, FIG.
There was a problem that the space in the upper direction becomes large.

In a manual transmission having a horizontal shift and select shaft as shown in FIG. 12, a "battery" and an "air cleaner" arranged above the transmission.
Will not be able to secure sufficient clearance with

Further, even in a manual transmission in which the shift and select shaft is vertically installed, the limitation of mountability due to the increased space cannot be ignored.

In the above-mentioned first and second conventional devices, since the shift characteristic is originally different for each shift, the inertia effect corresponding to each characteristic is necessary. However, the inertia effect due to the inertia mass M ( Equivalent mass) becomes the same at all gears.

As an example, first speed / first (1st)
In addition, the second (2nd) low shift has a problem that a large inertial effect is required to reduce the peak load because the shift operation load is generally large.

On the contrary, in the fifth (5th) and sixth (6th) high shifts, since the shift operation load is generally small, if a large inertia is applied, the "weight" is generated during the shift operation. There was a problem that "dullness" was noticeable.

Therefore, the inventor of the present invention has proposed a shift of a manual transmission for an automobile in which an outer lever which has a shift cable locked at one end thereof and swings around the axis of the shift and select shaft moves in the axial direction of the shift and select shaft. In the device, an inertial lever that engages with the outer lever and has an inertial mass is disposed so as to extend in the select direction of the outer lever, and swings according to the swinging of the outer lever. As a result of further research and development focusing on the technical idea of the present invention, the object is to solve the problems that occur when a weight is added to the control shaft in order to improve the shift feeling. In addition to increasing the effect of the mass, it also eliminates the need for a large mass as an inertial mass and suppresses the influence of the select operation. It has reached the present invention to achieve the object of reducing as compared with the conventional space.
