Description

  The present invention relates to a vehicle control cable mounting structure.

  For example, a vehicle including a control cable that connects a shift lever and a transmission is known (see, for example, Patent Document 1). A mounted member having a shaft portion is provided on the transmission side, and a cylindrical mounting member inserted through the shaft portion is provided at an end portion of the control cable. The attachment member is inserted through the shaft portion of the member to be attached, and the attachment member is fixed so as to be slidable around the shaft portion. Such a control cable transmits the force to the mounted member while sliding the mounting member around the shaft portion by the force transmitted by operating the shift lever.

  If rust is generated between the shaft portion and the sliding surface of the mounting member, the mounting member may adhere to the shaft portion. When the mounting member is fixed to the shaft portion in this manner, the mounting member cannot be slid, and there is a problem that it is difficult to transmit the operation of the shift lever to the mounted member. For such a problem, it is conceivable to prevent rust by applying a lubricant such as grease around the shaft portion. However, the connecting portion between the mounting member and the mounted member is outside the room, and a slight gap is provided between the shaft portion and the mounting member for smooth sliding. Therefore, it cannot be expected to have a rust prevention effect over a long period of time.

  As shown in FIGS. 1 to 3, the attachment member 22 is a cylindrical member having an insertion hole 23 that penetrates along the thickness direction at the center. The material of the attachment member 22 is not particularly limited, but can be formed from, for example, resin or metal. Further, the insertion hole 23 has a shape into which the shaft portion 11 can be inserted, and has a diameter larger than the diameter of the shaft portion 11.

  As shown in FIGS. 3 and 5, the attachment member 22 is provided with a sliding portion 24 on the inner peripheral surface of the insertion hole 23. The sliding portion 24 is formed in a protruding shape that protrudes toward the center of the insertion hole 23 and passes through an opening 34 of a seal member 30 described later. The sliding portion 24 is formed such that the tip surface slides on the side surface of the shaft portion 11. The sliding portion 24 does not need to have the tip end surface strictly in contact with the side surface of the shaft portion 11 and may have a slight gap (tolerance).

  As shown in FIGS. 1 to 4, the seal member 30 is a cylindrical member provided between the inner peripheral surface of the insertion hole 23 and the shaft portion 11 inserted through the insertion hole 23. A closed space 50 capable of holding the lubricant is formed between the two. The seal member 30 is preferably made of an elastic material.

  Specifically, a first protrusion 31 and a second protrusion 32 are provided on the inner peripheral surface of the seal member 30 and are made of a cylindrical elastic material. The first projecting portion 31 and the second projecting portion 32 are annular portions that protrude toward the shaft portion 11 side (center side of the seal member 30) and extend along the inner peripheral surface of the seal member 30. The first protrusion 31 and the second protrusion 32 are provided at both ends of the seal member 30, that is, near the two openings of the seal member 30, respectively. By forming the first protrusion 31 and the second protrusion 32 as described above, a recess 33 that is relatively recessed is formed between the first protrusion 31 and the second protrusion 32. Has been.

  Such a seal member 30 forms a closed space 50 between the first protrusion 31 and the second protrusion 32 in a state where the first protrusion 31 and the second protrusion 32 are in contact with the shaft portion 11. To do. That is, the closed space 50 is formed by the side surface of the shaft portion 11, the first protrusion portion 31, the second protrusion portion 32, and the recess portion 33.

  In addition, two openings 34 are provided on the side surface of the seal member 30. The opening 34 is a through hole formed to have a size that allows the sliding portion 24 of the mounting member 22 to be inserted. The sliding portion 24 is inserted through the opening 34 of the seal member 30, and the distal end surface thereof faces the side surface of the shaft portion 11.

  The opening 34 is in a state of being blocked by the sliding portion 24 inserted therethrough. Therefore, in this embodiment, the closed space 50 is formed by the sliding member 24 inserted through the seal member 30, the shaft portion 11, and the opening 34.

  The lubricant 40 is filled in the closed space 50. As the lubricant 40, general grease can be used. Since the lubricant 40 is filled in the closed space 50, the occurrence of rust on the side surface of the shaft portion 11 is prevented, and the lubricant 40 is prevented from leaking to the outside.

  Operation | movement of the attachment structure 1 of the structure demonstrated above is demonstrated. When a force that pushes the shaft portion 11 by the cable 21 (a leftward force in the Y direction in the figure) is applied, as shown by the arc-shaped arrow, the mounted member 10 rotates to the left about the Z axis around the base end side. Move. Similarly, when a force pulling the shaft portion 11 by the cable 21 (a rightward force in the Y direction in the figure) is applied, the attached member 10 moves around the Z axis with the base end side as the center, as indicated by an arcuate arrow. Rotate to the right.

  At this time, since the mounting structure 1 is filled with the lubricant 40 in the closed space 50 around the shaft portion 11, the shaft portion 11 and the insertion hole 23 of the mounting member 22 rotate smoothly while sliding. Can move. And since the closed space 50 is maintained also by such rotation, it is suppressed that the lubricant 40 leaks outside.

  According to the mounting structure 1 of this embodiment, since the lubricant 40 that smoothly slides the mounting member 22 around the shaft portion 11 is held in the closed space 50 formed by the seal member 30, For a long period of time, it is possible to suppress the vehicle control cable 20 from being fixed to the mounted member 10 to be attached.

  As shown in FIGS. 2 and 5, the sliding portion 24 is provided on an extension line of the shaft of the cable 21. In other words, the sliding portion 24 is arranged to pass through a straight line along the direction of the force transmitted from the cable 21 to the shaft portion 11 (Y direction in the figure). In the present embodiment, in the Y direction of the mounting member 22, one sliding portion 24 is provided on the cable 21 side with respect to the shaft portion 11, and another sliding portion on the opposite side of the cable portion 21 from the shaft portion 11. 24 is provided.

  Of the first projecting portion 31 and the second projecting portion 32 of the seal member 30, a region that receives a load from the cable 21 in the vicinity of the extension line of the shaft of the cable 21 is referred to as a loaded portion 35. In other words, a region of the first protrusion 31 and the second protrusion 32 that overlaps the opening 34 in plan view is the loaded portion 35. The first projecting portion 31 and the second projecting portion 32 appearing in the cross section of FIG. 3 are the loaded portions 35, and the hatched portions of FIG. 2 are the loaded portions 35.

  When a force pushing the shaft portion 11 is transmitted from the cable 21, the loaded portion 35 is compressed to the shaft portion 11 and the attachment member 22. On the other hand, the sliding portion 24 abuts on the shaft portion 11 due to the pushing force, and thus the loaded portion 35 has a structure that is not excessively compressed by the shaft portion 11 and the mounting member 22.

  According to the mounting structure 1 of this embodiment, since the portion 35 to be loaded is prevented from being excessively compressed, the sealing member 30 can be prevented from breaking. Thereby, it can suppress more reliably that a part of seal member 30 fractures | ruptures and the lubricant 40 leaks out of the closed space 50.

  Furthermore, in this embodiment, an opening 34 is provided in the seal member 30, and the sliding portion 24 of the attachment member 22 is inserted through the opening 34. With such a configuration, the sliding portion 24 can restrict the seal member 30 from coming out of the insertion hole 23, and the state where the lubricant 40 is filled in the closed space 50 more reliably. Can be maintained.

  Further, according to the mounting structure 1 of the present embodiment, the closed space 50 can be formed between the seal member 30 and the shaft portion 11 by providing the first protrusion 31 and the second protrusion 32 on the seal member 30. That is, the shaft portion 11 is not provided with a configuration for forming the closed space 50, and the first protrusion 31, the second protrusion 32, and the recess 33 for forming the closed space 50 are provided on the seal member 30 side. . Thereby, if the seal member 30 having a predetermined shape is used, the closed space 50 for filling the lubricant 40 can be formed without changing the shape of the shaft portion 11. When the closed space 50 for filling the lubricant 40 in the shaft portion 11 is formed, the lubricant 40 is exposed to the outside, and foreign matters such as dust may adhere to the lubricant 40. Therefore, when the closed space 50 is formed inside the seal member 30 and the lubricant 40 is applied, there is less possibility of foreign matter adhering, and since the lubricant 40 is not exposed, it is easy to handle and easy to assemble. improves.
