It relates to a shift cable bracket.

Generally, a transmission of a vehicle is installed between a clutch and a propulsion shaft, and is a device for changing a rotational force and a speed of engine power to be transmitted to a driving wheel so as to be suitable for a driving state of a vehicle.

In order to achieve a shift in accordance with the state of the vehicle through such a transmission, a driver usually converts a gear engagement state of the transmission using a shift lever, wherein the operating force of the shift lever is between the shift lever and the transmission. It is transmitted by a shift cable connected to.

On the other hand, in order to prevent the noise generated when the vibration generated from the transmission flows into the interior of the vehicle during the operation of the transmission in the prior art, the shift cable is mounted to the bracket housing to which the shift cable is fitted to the shift Absorb vibrations transmitted on the cable.

However, the vehicle shift cable bracket 10 according to the related art as described above is the first plate when the deformation occurs in the first plate 20 or the first and second stoppers 41 and 42 made of metal. 20 and one end of the first and second stoppers 41 and 42 are in contact with each other to cause interference, thereby reducing the vibration absorbing effect in the insulating member 43 and reducing the noise transmitted to the interior of the vehicle. There is a problem.

The present invention has been made to solve the above problems of the prior art, by changing the shape of the stopper of the vehicle shift cable bracket, to prevent the interference by the contact between the stopper and the plate of the bracket to increase the vibration absorption effect and noise It is an object of the present invention to provide a shift cable bracket for a vehicle that can be reduced.

The shift cable bracket for a vehicle according to the present invention for solving the above problems includes a first plate having a groove formed so that the shift cable is fitted and fixed, and a second plate integrally formed with the first plate so that the shift cable is placed therein. A first stopper disposed between the first plate and the second plate such that both side portions are bent toward the first plate side, and arranged to be symmetrical with the first stopper with respect to the first plate, and both side portions A second stopper curved toward the first plate side, an insulating member attached to both sides of the first plate to absorb vibration transmitted to the shift cable, and between the first and second plates and the first and second stoppers. Characterized in that it further comprises a fastening bolt penetrating.

In addition, to reduce the weight of the insulating member, one side of the insulating member attached to the first plate is characterized in that the stepped portion of a predetermined depth is formed.

In addition, the insulating member is formed up to an outer end of the first and second stoppers and attached to both sides of the first plate so as to prevent interference due to contact between the first and second stoppers and the first plate. It is done.

In addition, the material of the insulating member is rubber, characterized in that it is produced by a vulcanization process and attached to the first plate.

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

Figure 4 is a cross-sectional view showing a shift cable bracket for a vehicle according to the present invention, Figure 5 is a side cross-sectional view of Figure 4, Figure 6a is a graph comparing the measured noise before and after the insulation according to the conventional invention, Figure 6b according to the present invention This is a graph comparing the measured noise before and after insulation.

As shown in FIG. 4, the vehicle shift cable bracket 50 according to the present invention includes a first plate 60 having grooves formed therein so that the shift cable (not shown) is fitted and the shift cable (not shown) is disposed. It is configured to include a second plate 70 formed integrally with the first plate 60 to lose.

One side of the first plate 60 is formed with a groove open toward the upper side, the shift cable (not shown) is fitted into the groove.

The shift plate (not shown) is placed on the second plate 70, and an insulating member (not shown) is attached to an upper surface of the second plate 70 so as to absorb vibration of the shift cable (not shown).
