[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support device capable of absorbing vibration between a hydraulic power steering device and a vehicle body when supporting the hydraulic pipe, for example.

[0002]

[Prior art]

 FIG. 5 shows a conventional pipe support device (see Japanese Utility Model Laid-Open No. 60-111756 and Japanese Utility Model Laid-Open No. 60-143976), which includes a clamp member 102 for a pipe 101 and a cylindrical holder 104 for an elastic member. . A through hole 103 as shown in FIG. 6 is formed in the clamp member 102, and the holder 104 is inserted into the through hole 103. The holder 104 has a circumferential groove 105 on the outer circumference, and the peripheral portion 102a of the through hole 103 is sandwiched by the inner surfaces 105a and 105b of the circumferential groove which face each other, so that the clamping member 102 is held by the holder 104. There is. The head bolt 106 is inserted into the holder 104 and the member 107 to be attached via a washer 110, and a nut 111 is screwed to the insertion end.

In the pipe support device as described above, since the peripheral portion 102a of the through hole 103 needs to be sandwiched between the inner surfaces 105a and 105b of the circumferential groove 105 which face each other, the outer diameter of the holder 104 is equal to the peripheral diameter. It is made larger than the inner diameter of the through hole 103 except for the groove 105 portion. Therefore, as shown in FIG. 5, a notch 108 that connects the inside of the through hole 103 and the outside of the clamp member 102 is formed, and the holder 104 is flatly deformed as shown by the phantom line in the drawing. Is inserted into the through hole 103 through the notch 108.

Since the holder 104 needs to be deformed flat in this way, the hardness of the holder 104 is reduced. Therefore, when the holder 104 is attached to the attachment-side member 107 with the bolt 106, the collar 109 having a hardness higher than that of the holder 104 is inserted into the holder 104, and the collar 109 supports the tightening force of the bolt 106. It was

[0005]

[Problems to be solved by the device]

 In the above-described conventional configuration, if the collar 109 is forgotten to be inserted into the holder 104, the mounting strength of the holder 104 is significantly reduced. Further, if the hardness of the holder 104 is made too small, the clamp 102 cannot be held sufficiently, so the hardness of the holder 104 needs to be set to a certain level or more. Therefore, labor is required to flatten the holder 104 and insert it into the through hole 103 through the notch 108. Further, when the notch 108 is formed in the clamp 102, there is a problem that the strength of the clamp 102 itself is lowered.

It is an object of the present invention to provide a pipe support device that can solve the above-mentioned problems of the prior art.

[0007]

[Means for Solving the Problems]

 A feature of the present invention is that it includes a clamp member for piping and a cylindrical holder made of an elastic material that is inserted into a through hole formed in the clamp member, and the holder has a circumferential groove on the outer circumference. The clamping member is held in the holder by the inner surfaces of the circumferential groove facing each other sandwiching the peripheral portion of the through hole, and the bolt is inserted into the holder to attach the holder to the mounted member. In the device, the holder is configured by joining a tubular first member on one axial side and a tubular second member on the other axial side, and the holder is connected to at least one of the first member and the second member. An insertion portion to be inserted into the hole is formed, and the peripheral groove is formed by the end surfaces of the first member and the second member which face each other and the outer peripheral surface of the insertion portion.

[0008]

[Action]

 According to the configuration of the present invention, at least one of the first member and the second member forming the holder is inserted into the through hole of the clamp member that clamps the pipe, and then the first member and the second member are inserted. The holder is constructed by joining the. The end faces of the first member and the second member facing each other and the outer peripheral surface of the insertion portion form a peripheral groove on the outer periphery of the holder. As a result, the holder can be inserted into the through hole of the clamp member without being flatly deformed, so that the work effort can be reduced, and the hardness of the holder need not be so small that it can be flatly deformed. Therefore, the hardness of the holder can be made as large as necessary to support the tightening force of the bolt inserted into the holder, and the collar inserted into the holder as in the conventional case is unnecessary. Further, when the holder is inserted into the through hole of the clamp member, it is possible to eliminate the notch that connects the inside of the through hole and the outside of the clamp member.

Both members are made of rubber, and the rubber hardness of the first member 5 is higher than that of the second member 6. The first member 5 has a large-diameter portion 5a whose outer diameter is larger than that of the through hole 4 of the clamp member 2 and an insertion portion 5b which is slightly smaller, and the inner peripheral hole 5c of which the bolt 10 is inserted. It is a hole, and the axial length of the insertion portion 5b is larger than the thickness of the clamp member 2. The second member 6 has an outer diameter equal to the outer diameter of the large diameter portion 5 a of the first member 5, an inner diameter equal to the through hole 4 of the clamp member 2, and an axial length of the first member 5. It is made equal to the difference between the axial length of the insertion portion 5b and the thickness of the clamp member 2.

As a result, the holder 3 can be inserted into the through hole 4 of the clamp member 2 without being flatly deformed, so that the work effort can be reduced, and the hardness of the holder 3 can be made flat enough to be flatly deformed. No need. Therefore, in this embodiment, the rubber hardness of the first member 5 is set to a value required to support the tightening force of the bolt 10, and the collar inserted in the holder as in the conventional case is unnecessary. Further, when the holder 3 is inserted into the through hole 4 of the clamp member 2, a notch for communicating the inside of the through hole 3 with the outside of the clamp member 2 is not necessary, so that the strength of the clamp member 2 can be improved.

The present invention is not limited to the above embodiment.

For example, FIG. 3 shows a first modification of the present invention, which is provided with a holder 30 different from the holder 3 of the above embodiment. That is, the holder 30 is made of rubber and is configured by joining the tubular first member 31 on one side in the axial direction and the tubular second member 32 on the other side in the axial direction. The first member 31 has a large-diameter portion 31a whose outer diameter is larger than that of the through hole 4 of the clamp member 2 and an insertion portion 31b which is slightly smaller than the through-hole 4, and the inner peripheral hole 31c has the bolt 10 inserted therethrough. The insertion portion 31b has a hole, and the axial length of the insertion portion 31b is equal to the thickness of the clamp member 2. The outer diameter of the second member 32 is equal to the outer diameter of the large diameter portion 31a of the first member 31, and the inner peripheral hole 32c is an insertion hole for the bolt 10. As a result, the peripheral grooves 33 are formed on the outer periphery of the holder 3 by the end faces 31 ′ and 32 ′ of the first member 31 and the second member 32 facing each other and the outer peripheral face 31 b ′ of the insertion portion 31 b of the first member 31. Has been done. Others are the same as the above-mentioned embodiment, and the same portions are denoted by the same reference numerals.

FIG. 4 shows a second modification of the present invention, which includes a clamp member 50 and a holder 40 different from the holder 3 of the above embodiment. That is, the clamp member 50 is configured by connecting two members 50a and 50b with a pair of bolts and nuts 52 and 53, and a cylindrical portion 50c is provided between one bolt and nut 52 and the other bolt and nut 53. The pipe 1 formed and inserted into the cylindrical portion 50c is clamped by sandwiching it with the elastic member 54 interposed therebetween. A through hole 51 is formed at the other end. The holder 40 is made of rubber and is configured by joining a tubular first member 41 on one side in the axial direction and a tubular second member 42 on the other side in the axial direction. The first member 41 has a large diameter portion 41a having an outer diameter larger than that of the through hole 51 of the clamp member 50 and an insertion portion 41b slightly smaller than the through hole 51. The inner peripheral hole 41c serves as an insertion hole for the bolt 10. The axial length of the insertion portion 41b is 1/2 of the thickness of the clamp member 50. The second member 42 has a large-diameter portion 42 a whose outer diameter is equal to the outer diameter of the large-diameter portion 41 a of the first member 41, and an insertion portion 42 b which is slightly smaller, and the inner peripheral hole 42 c has a bolt 10 having a large diameter. And the axial length of the insertion portion 42b is 1/2 of the thickness of the clamp member 50. As a result, the first member 41 and the second member 42 have opposite end surfaces 41 ′ and 42 ′ and the outer peripheral surfaces 41 b ′ and 42 b ′ of the insertion portions 41 b and 42 b of the two members 41 and 42, respectively. A circumferential groove 43 is formed. Others are the same as the above-mentioned embodiment, and the same portions are denoted by the same reference numerals.

In each of the modified examples, the rubber hardness of the first member 31, 41 and the rubber hardness of the second member 32, 42 may be the same or different, but by making them different, the first member 31, It is also possible to reduce the noise and vibration by making the natural frequencies of 41 and the second members 32, 42 different from each other.

The material of the holder is not limited to rubber as long as it is an elastic material, but as the rubber material, chloroprene rubber, ethylene propylene rubber, butyl rubber or the like can be used. Although the through hole of the clamp member is closed in the above-described embodiment, it may have a notch for communicating the inside of the through hole with the outside of the clamp member as shown in the conventional example. The present invention can also be applied to a device that supports pipes other than the pipe of the hydraulic power steering device.
