Definitions
- the outer peripheral shape of the fixing portion of the joint cup to which the boot is attached has a cylindrical shape, and has an irregular shape (tripod) having three curved concave portions.
- the inner periphery of the fixed portion of the boot has a tripod shape according to the shape of the outer periphery of the fixed portion of the cup, and the outer periphery of the fixed portion of the boot has a cylindrical shape. Then, the outer periphery of the fixed part of the boot was tightened with a band, and the boot was fixed to the cup.
- a boot 101 is formed into a case having a tripod shape ( (Not shown), an adapter member 110 having a circular outer peripheral surface 111 and an inner peripheral surface 113 on which a convex portion 112 corresponding to a tripod shape on the outer periphery of the case fixing portion is formed. It is made separately from the main body. Then, the adapter 110 is fitted into the inside of the boot 101 and further attached to the case to cover and protect the movable mechanism of the constant velocity joint.
- Patent Document 2 Japanese Utility Model Publication No. 60-64362
- the present invention has been made in view of the above-mentioned problems of the related art, and an object of the present invention is to provide a universal joint boot with good assemblability.
- An expandable and contractible cylindrical bellows portion in which a valley portion and a peak portion are continuously formed repetitively, and a case for storing one of two relatively movable members provided at one end of the bellows portion.
- a boot body having an opening into which the boot is inserted, and
- a universal joint boot comprising:
- the adapter is a first member of the adapter.
- the opening of the boot main body can be sandwiched after the adapter is assembled to the boot main body. Therefore, even if the boot main body is made of a material that is not easily deformed, it can be easily assembled.
- the reversing portion has a convex portion that presses the outer peripheral portion of the opening with an inward force.
- the adapter can more firmly sandwich the boot body, and the sealability is improved.
- the outer periphery of the fixing portion has an uneven surface in contact with the inner periphery of the boot body.
- the reversing section is provided with a mounting section for mounting a band in a state of being folded from the folding section.
- FIG. 2 is an external perspective view showing a state in which the boot according to the present embodiment is mounted on a case.
- the universal joint boot 10 used for the constant velocity joint includes the boot main body 1 and an annular adapter 20 attached to the boot main body 1.
- the boot body 1 includes a telescopic tubular bellows portion in which a valley portion and a peak portion are continuously formed repeatedly, and one of two relatively movable members provided at one end of the bellows portion.
- the annular adapter 20 is attached to the inner peripheral surface of the opening 2 of the boot main body 1, and has an outer peripheral surface having substantially the same shape as the inner peripheral surface.
- the universal joint boot 10 has the opening of the joint cup (case) 40 that houses one of the two relatively movable shafts with the adapter 20 attached to the boot body 1. It is fitted on the outer periphery and fixed to the cup 40 by the band 30.
- FIG. 1 is a schematic configuration diagram of a universal joint boot according to the first embodiment
- FIG. 3 is a half cross-sectional view of the adapter according to the first embodiment.
- the adapter 20 has an annular shape in which the outer peripheral surface 21 has a circular shape and the inner peripheral surface 22 has an irregular (tripod) shape having three curved convex portions 23. It is a member.
- the adapter 20 according to the present embodiment also has a rubber or elastic blast force. More preferably
- the adapter 20 is first manufactured as a hollow cylindrical member by, for example, molding (see FIG. 3). See).
- the adapter 20 as a cylindrical member includes a fixing portion 24 fixed to the boot body 1 by the band 30, a folded portion 25 having a smaller thickness than the fixing portion 24 to facilitate folding, and a boot body 1 after being folded. And an inversion section 26 that sandwiches one opening 2.
- the adapter 20 is inserted from one opening 2 of the boot body 1 to a predetermined position, and the folded portion 25 is folded outward so as to sandwich the opening 2.
- the boot body 1 is firmly clamped by the adapter 20, and the sealing performance is improved.
- the opening 2 of the boot main body 1 is sandwiched after the adapter 20 is assembled to the boot main body 1, even if the boot main body 1 is made of a material that is not easily deformed, the boot main body 1 can be easily assembled.
- the reversing portion 26 is provided with a convex portion 26a so as to press the outer peripheral surface of the edge of the opening 2.
- the convex portion 26a is provided so as to protrude toward the inside of the adapter 20 in a state where the reversing portion 26 is folded back at the folding portion 25.
- a notch 27 may be provided from the reversing portion 26 to the folded portion 25 (see FIG. 4). Thereby, even if the adapter 20 is hard, the reversing portion 26 can be easily turned back, and the assemblability can be improved.
- the number of the notches 27 can be appropriately selected depending on the material, size, and thickness of the adapter 20. Preferably, the notches 27 are provided at equal intervals. With this configuration, the opening 2 of the boot body 1 can be sandwiched with an equal force in a state where the reversing portion 26 is folded back.
- An uneven surface 24a may be provided on the outer periphery of the fixing portion 24 (see Fig. 5). This makes it difficult for the boot body 1 to be detached from the adapter 20, and the boot body 1 is firmly fixed to the cup 40 by the band 30.
- FIG. 6 is a schematic configuration diagram of a universal joint boot according to the second embodiment
- FIG. 7 is a half cross-sectional view of the adapter according to the second embodiment.
- the first embodiment will be described with a focus on different configurations, and other configurations will be omitted as appropriate.
- the adapter 20 includes a fixed portion 24 fixed to the boot body 1 by the band 30, a folded portion 25 having a smaller thickness than the fixed portion 24 to facilitate folding, and a folded portion 25. And a reversing portion 26 that sandwiches one opening 2 of the boot body 1 later.
- the reversing portion 26 is extended from the folded portion 25 to a position facing the outer periphery of the fixed portion 24 in a state of being folded back.
- the reversing section 26 is provided with a mounting section 26b for the band 30.
- the mounting portion 26b is provided on the outer periphery of the reversing portion 26 in a state where the reversing portion 26 is folded back at the folding portion 25. Further, in the mounting portion 26b, a part of the reversing portion 26 is depressed over the entire circumference, as in the case V where the mounting position of the band 30 is not shifted.
- the reversing part 26 does not necessarily have to be linear with respect to the fixed part. As shown in FIG. The inner diameter of the portion 26 may be increased. This makes it easier to fold and to provide a universal joint boot with good assemblability.
- FIG. 1 is a schematic configuration diagram of a universal joint boot according to Embodiment 1.
- FIG. 2 is an external perspective view showing a state in which the boot according to the embodiment is mounted on a case.
- FIG. 3 is a half sectional view of the adapter according to the first embodiment.
- FIG. 4 is a half sectional view of the adapter according to the first embodiment.
- FIG. 5 is a half sectional view of the adapter according to the first embodiment.
- FIG. 8 is a half sectional view of an adapter according to a second embodiment.
