Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile clutch control cable, and particularly to an outer cable thereof.

Generally, the clutch control cable is installed inside the engine compartment, so one end is connected to the clutch pedal.
An outer cable is loosely fitted around the outer periphery of an inner cable whose other end is connected to a clutch release lever.

With a latch control cable like this, vibrations and noise are transmitted to the cable and enter the vehicle interior.
In order to suppress this, for example, Utility Model Application No. 55-13663
Several countermeasures have been proposed for inch cables, such as one in which a damper weight is fixed to the inner cable like N.

However, vibrations and noise enter the vehicle interior not only through the inner cable but also through the outer cable, and at present, no sufficient countermeasures have been taken to deal with this problem.

The present invention has been devised in view of the above, and its main purpose is to provide a clutch control cable for an automobile that can block vibrations and noise from entering the vehicle interior via the outer cable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a clutch control cable, and an outer cable 5 is loosely fitted around the outer periphery of an inner cable 4 whose one end is connected to a clutch pedal 2 and the other end is connected to a clutch release lever 3. .

The outer cable 5 has one end attached to a dash panel 6 and the other end attached to a mounting member 9 fixed to a housing 8 of a transmission connected to an engine 7.

The outer cable 5 is divided into a first part 5a and a second part 5b midway near the dash panel 6, and first and second cylindrical metal fittings 11. It is integrated by connecting a pair of metal fittings 12 and an elastic material 13 such as synthetic leather and rubber (see Fig. 2).

The first metal fitting 11 includes a small-diameter cylindrical portion 11a that is fitted onto the outer periphery of the first portion 5a, and a second portion 5 that is coaxial with the cylindrical portion 11a.
a large-diameter cylindrical portion 11b extending in the direction b, an annular connecting portion 11c orthogonal to the axis of the outer cable 5 and connecting the two portions 11a and llb, and an annular connecting portion 11c extending inward from the inner edge of the connecting portion 11c and a protective portion 11d along the end surface of the first portion 5a.

The second metal fitting 12 is connected to a cylindrical part 12a that is fitted on the outer periphery of the second part 5b and has approximately the same diameter as the cylindrical part 11a of the first metal fitting 11, and an end of the cylindrical part 12a on the first part 5a side. Serakatsu 2nd
A protective portion 12b is provided along the end surface of the portion 5b and substantially perpendicular to the axis of the outer cable 5.

An elastic material 13 is interposed in an annular space formed between the cylindrical portion 11b of the first metal fitting 11 and the cylindrical portion 12a of the second metal fitting 12, and is fixed to both the fittings 11 and 12. ,
Both parts 11, 12 are integrally and elastically connected.

Note that the elastic material 13 is fixed by baking to both of the fittings 11 and 12.

The first metal fitting 11 also has a second metal fitting 11 that faces the first metal fitting 11.
A stopper surface 11e that restricts movement of the end surface 12c of the protective portion 12b in the metal fitting 12 in the axial direction is connected to the connecting portion 11c.
and the opposing end surfaces of the protective portion 11d.

The stopper surface lie of the first metal fitting 11 and the end surface 12c of the second metal fitting 12 are different from each other when the clutch is not operated (normally when the foot is not placed on the clutch pedal 2 and when the clutch pedal 2 is
(when you put your foot on it), they face each other with a small gap S□.

With the above configuration, during normal times when the foot is not placed on the clutch pedal 2, the first
Since the portion 5a and the second portion 5b, that is, the stopper surface 11e of the first metal fitting 11 and the end surface 12c of the second metal fitting 12 are separated from each other with a slight gap S1, the first portion of the outer cable 5 Vibration and noise transmitted through 5a are caused by elastic material 13
It is absorbed and relaxed by the vehicle body (dash panel 6), and is hardly transmitted to the vehicle body (dash panel 6).

In particular, since the connecting portion between the first portion 5a and the second portion 5b is located near the dash panel 6, absorption and mitigation of vibrations and noise can be efficiently performed.

In addition, when the driver puts his foot on the clutch pedal 2 (clutch operation is not yet performed), the inch cable 4 is slightly pulled, but as shown in FIG.
The first portion 5a and the second portion 5b have a gap S2 (<sl)
Since the vibrations and noises are separated from each other by the elastic material 13, the vibrations and noises are absorbed and relaxed by the elastic material 13 and are hardly transmitted to the vehicle body, as in the normal case described above.

Furthermore, when the driver depresses the clutch pedal 2 to operate the clutch, as shown in FIG.
The end surface 12c of the second metal fitting 12 is regulated to contact the portion 5b, that is, the stopper surface lie of the first metal fitting 11, and the first portion 5
Since the second portion 5b and the second portion 5b are directly connected to each other and become similar to one cable, the clutch can be operated without impairing the operation feeling.

Instead of the pair of metal fittings 11 and 12 used in the above embodiment,
As shown in FIG. 5, a pair of cylindrical fittings 21.22 are provided at opposite ends of the first and second portions 5a, 5b of the outer cable 5, and both fittings 21.22 are elastically connected. Even a simple structure in which the outer cable 5 is elastically coupled is sufficiently effective in preventing vibrations and noise from entering the vehicle interior from the outer cable 5.

The present invention divides the outer cable as described above,
A pair of metal fittings fixed to both ends of the split part are integrally and elastically connected using an elastic material, which is practically excellent in that vibrations and noise from the outer cable are blocked from entering the vehicle interior. have an effect.
