Abstract

PURPOSE:To prevent propagation of oscillations from an outer cable to a vehicle body panel through a gromet. CONSTITUTION:An accelerating pedal is connected to a throttle valve by means of an inner cable 8 of a double cable which penetrates a vehicle body panel. A cushion rubber 20 is installed on a certain part of an outer cable 6 of the double cable, which part ranges from a vehicle body penetrating portion to the side of an engine room 2. The outer cable 6 is installed on the vehicle body panel 1 through the cushion rubber 20. It is thus possible to suppress oscillation transmission from an engine to the outer cable 6, and reduce noise transmittion to a vehicle room.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable floating device which can be applied to a vehicle in which an accelerator pedal and a throttle valve are connected by a double cable.
The engine vibration is prevented from being transmitted to the vehicle body panel via the double cable.

[0002]

2. Description of the Related Art A conventional apparatus will be described with reference to FIGS. 2 and 3. Reference numeral 1 denotes a panel of a vehicle body, for example, a dash panel for partitioning an engine compartment 2 and a vehicle compartment 3.
A hole 4 is provided in the vehicle body panel 1 and a grommet 5 is fitted therein, and one end of an outer cable 6 which is a double cable is supported inside the grommet 5. The other end of the outer cable 6 is held by the engine body 7.

An inner cable 8 is slidably provided inside the outer cable 6. The inner cable 8 functions as a slot cable, one end of which is locked to an upper end of an accelerator pedal 11 supported by a shaft 10 on a bracket 9 provided on the vehicle body panel 1, and the other end of which is attached to the engine body 7. It is connected via a lever 13 to a throttle valve (not shown) provided on a provided throttle body 12.

A claw 14 is provided at an end of the grommet 5 fitted to the vehicle body panel 1 on the vehicle compartment 3 side, and an outer cable 6 is provided around the body of the grommet 5 on the engine room 2 side. The cushion rubber 15 for suppressing the vibration of the is fitted. The claw 16 of the cushion rubber 15 and the claw 14 of the grommet 5 are in contact with the vehicle body panel 1 to fix the grommet 5 to the vehicle body panel 1. In the figure,
Reference numeral 17 is a clip for fixing the grommet 5 to the outer cable 6. Reference numeral 18 in FIG. 2 is an intake manifold between the throttle body 12 and the engine body 7, and 19 is an air cleaner.

As a soundproof device for the cable swing part,
There is one disclosed in Japanese Utility Model Publication No. 60-77216. The gazette disclosed in this publication has a grommet cover in which a sound absorbing material is mounted on a grommet mounted in a through hole of a dash panel, so that the sound absorbing material faces the grommet. There is also a grommet that is used in a water pool of a vehicle device (see Japanese Utility Model Publication No. 1-39665).

[0006]

In the prior art described above, since the claw provided at the end of the grommet on the vehicle interior side is in contact with the vehicle body panel, vibration from the outer cable passes through the grommet. There was a problem that it propagated to the vehicle body panel and became noise to the passenger compartment.

Since the grommet is in contact with the dash panel in the soundproofing device for the cable swaying portion disclosed in Japanese Utility Model Laid-Open No. 60-77216, there is a possibility that vibration from the cable may propagate. Has not solved the problem.

The present invention has been made to solve the above-mentioned conventional problems. By mounting the outer cable in a floating manner from the vehicle body panel, vibration from the outer cable is prevented from propagating from the grommet to the vehicle body panel, and noise is prevented. It aims at providing the cable floating apparatus which eliminated.

[0009]

As a means for solving the above problems, the present invention connects an accelerator pedal in a vehicle compartment and a throttle valve in an engine compartment with an inner cable that is a double cable that penetrates a vehicle body panel, A cushion rubber is attached to the engine room side portion from the body panel penetrating portion of the outer cable of the double cable, the outer cable is attached to the body panel via the cushion rubber, and the cushion rubber is fixed with a grommet. It is characterized by.

[0010]

As described above, according to the present invention, the outer cable is attached to the vehicle body panel through the cushion rubber attached to the engine room side portion from the vehicle body panel penetrating portion of the outer cable, and the cushion rubber is fixed by the grommet to make the outer cable. Since it is attached to the vehicle body panel in a floating manner, it is possible to suppress the vibration transmitted from the engine to the outer cable by the cushion rubber. This makes it possible to reduce noise to the passenger compartment.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 with the same members as those in FIGS. An outer cable 6, which is a double cable, penetrates through a vehicle body panel 1, which is a dash panel that partitions the engine compartment 2 and the vehicle compartment 3. An inner cable 8 slidably provided inside the outer cable 6 connects an accelerator pedal 11 and a throttle valve (not shown) shown in FIG.

A cushion rubber 20 having a T-shaped cross section is fitted to the outer periphery of the outer cable 6 from the penetrating portion of the vehicle body panel 1 to the engine room 2 side portion. Both ends of the cushion rubber 20 are fixed to the outer cable 6 by clips 21. Further, a grommet 22 attached to the vehicle body panel 1 from the engine room 2 side around the cushion rubber 20.
Is installed. The grommet 22 is provided with a claw 23, and the claw 23 is passed through the vehicle body panel 1 from the engine room 2 to the vehicle room 3 to engage the claw 23 to fix the grommet 22. As a result, the cushion rubber 20 is also fixed to the vehicle body panel 1.

If the outer cable 6 is attached to the vehicle body panel 1 as described above, the outer cable 6 is directly attached to the vehicle body panel 1.
Therefore, the cushion rubber 20 floats without contacting the.

Next, the operation of this embodiment will be described. In this way, the outer cable 6 is attached to the vehicle body panel 1 via the cushion rubber 20 attached to the engine room 2 side portion from the penetrating portion of the vehicle body panel 1 of the outer cable 6, and the cushion rubber 20 is fixed with the grommet 22. Since the outer cable 6 is attached to the vehicle body panel 1 in a floating manner, the cushion rubber 20 can suppress the vibration transmitted from the engine body 7 to the outer cable 6.

[0015]

As described above, according to the present invention, the outer cable is attached to the vehicle body panel through the cushion rubber attached to the engine room side portion from the vehicle body panel penetrating portion of the outer cable, and the cushion rubber is fixed with the grommet. Since the outer cable is attached to the vehicle body panel in a floating manner, the cushion rubber can suppress the vibration transmitted from the engine to the outer cable. This can reduce noise to the passenger compartment.
