Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support device for a transmission control cable.

[0002]

[Prior Art]

 In order to obtain the quietness of the automobile, it is necessary to prevent transmission of the vibration of the transmission into the passenger compartment as much as possible. For that purpose, it is effective to improve the vibration damping characteristics of the support device for the control cable of the transmission, which is one of the vibration conduction paths. However, in a control cable support device with a vibration-proof structure, if the hardness of the rubber is reduced, the damping property is improved, but the transmission's shift feeling is impaired, so the damping property is improved and the shift feeling is improved. It is difficult to combine the two functions.

Two examples of the support device for the control cable of the truss mission will be described with reference to FIGS. 8 and 9 and 10.

First, a first example will be described.

In FIG. 8, reference numeral 1 denotes a first bracket, which is composed of two plate members 1a and 1b which are superposed on each other, and a base portion 1c of which is supported by a transmission case. ing. A second bracket 4 is provided between the plate members 1a and 1b with a rubber member 2 interposed therebetween. Reference numeral 4a indicates a cable fixing portion of the cable outer 9 of the control cable. The hardness of the rubber material 2 is set high in order to suppress the deformation of the shift cable during the shift as much as possible and to obtain a sufficient shift operation force.

Next, a second example will be described.

In FIG. 9, reference numeral 11 denotes a first bracket, and the bracket 11 is a second bracket support that supports the fixing portion 11 a fixed to the transmission case 20 and the second bracket 12. It is composed of a part 11c. The second bracket 12 includes a cable fixing portion 12a that supports the cable outer 9 of the control cable, a supported portion 12b that is supported by the first bracket 11, and a free end portion 12c to which the other side surface of the rubber material is fixed. It is composed of and. As shown in FIG. 10, a supported portion 12b is fixed to the second bracket supporting portion 11c by screwing a bolt 15 into a weld nut 14 fixed to the first bracket 11. .. Both surfaces of the supported portion 12b are supported with a rubber material 16 interposed between the stopper members 13a and 13b.

Between the intermediate portion 11b of the first bracket 11 and the free end portion 12c of the second bracket 12, one side surface is fixed to the intermediate portion 11b and the other side surface is fixed to the free end portion 12c. A rubber material 17 is provided. The hardness of the rubber materials 16 and 17 is set small so that the vibration of the transmission can be sufficiently absorbed.

In this second example, the vibration of the transmission is sufficiently absorbed by reducing the hardness of the rubber materials 16 and 17, and the rubber deformation during the shift is limited by the stopper members 13a and 13b. The shift feeling is good.

[0010]

[Problems to be solved by the device]

 In the control cable supporting device shown in FIG. 8, the hardness of the rubber is set to be large so as not to impair the shift feeling, so that the vibration of the transmission cannot be sufficiently absorbed. However, there is a problem that the vibration damping characteristics cannot be improved.

Further, in the control cable supporting device shown in FIGS. 9 and 10, there is a problem that the number of parts such as the stopper members 13a and 13b, the bolt 15 and the weld nut 14 is increased and the structure is complicated.

[0012]

[Means for Solving the Problems]

 The present invention relates to a control cable supporting device for supporting a control cable on a transmission case. A first bracket having a support arm and a support portion for the control cable, and a small portion between the support arm and both sides of the support arm and both edges of the support arm in the moving direction of the control cable. The second bracket, which is bent in a U shape with a gap, is interposed between a surface of the second bracket facing the support arm and the support arm, and one side surface of the second bracket is supported by the support arm. The control cable supporting device includes a rubber material having the other side surface fixed to the facing surface.

[0013]

[Action]

 Since the control cable is supported by the control cable supporting device in which the rubber material is interposed between the second bracket and the first bracket, the vibration of the transmission case is absorbed by the rubber material.

Since both sides of the second bracket are supported by the support arm with a small gap therebetween, when the control cable is operated, both sides of the second bracket abut on both side edges of the support arm to control the control cable. The operating force of the cable is reliably transmitted to the first bracket.

Between the supporting surfaces 31bA, 31bB and the facing surfaces 32bA, 32bB, one side surface is fixed to the supporting surfaces 31bA, 31bB, and the other side surface is fixed to the facing surfaces 32bA, 32bB. 34, 34 are provided. The rubber material 34 is formed of rubber having a relatively small hardness so that the vibration of the transmission can be sufficiently absorbed.

As shown in FIG. 5, when the transmission is operated and the cable outer 9 of the control cable is moved in the direction of the arrow in FIG. 5, the friction force between the cable and the cable outer causes the second bracket 32 to move. Also, a force in the same direction is applied, the second bracket 32 also moves in the arrow direction due to the deformation of the rubber members 34, 34, the facing surface 32cA abuts against the side edge 31cA, and the operating force of the shift cable is controlled by the control cable supporting device. Be transmitted to.

Further, as shown in FIG. 6, when the shift lever is returned and the cable outer 9 is moved in the direction of the arrow in FIG. 6, a force in the same direction is also applied to the second bracket 32, The second bracket 32 moves in the direction of the arrow, and the facing surface 32cB contacts the side edge 31cB. The shift operation force is received by the control cable support device.

FIG. 7 shows the level of vibration sound from the transmission, which changes depending on the vehicle speed, between the conventional control support device shown in FIG. 8 and the control cable support device of the present invention. In FIG. 7, the alternate long and short dash line curve A indicates the vibration level of the conventional control cable supporting device shown in FIG. 8, and the solid line curve B indicates the vibration level of the control cable supporting device of the present invention. 7, the conventional control cable supporting device shown in FIG. 8 and the control cable supporting device of the present invention, as indicated by the one-dot chain line curve A and the solid line curve B, show the one-dot chain line curve A. The solid curve B is suppressed to a lower level than that. Therefore, the control cable supporting device of the present invention has a higher vibration reduction quantity than the conventional control cable supporting device shown in FIG.

In the above-described embodiment, the second bracket in which the other side surface of the rubber material 34, 34 is fixed to the inner side of the support arm 31 b to which one side surface of the rubber material 34, 34 is fixed is attached to the cable outer 9. Although the opposite surfaces 32bA and 32bB of the above are arranged outside, respectively, the present invention may be arranged such that the opposite support arm of the above example is arranged outside and the second bracket is arranged inside the opposite surface. Good.

[Effect of the device]

 According to the present invention, since the control cable is supported by the control cable support device in which the rubber material is interposed between the first bracket and the second bracket, the vibration of the transmission case is absorbed by the rubber material, and the transmission material is absorbed. The vibration damping characteristics of the vehicle are improved, and the vibrations are less likely to be transmitted to the passenger compartment. When the control cable is operated, the side edges of the second bracket and the sides of the second bracket make contact, which may impair the shift feeling. It is possible to provide a control cable supporting device that is few and has a simple structure.
