The torque receiving shaft portion 22 is a portion on which the pads 5 and 6 slide, and the slide shaft portion (not shown) is a portion on which the caliper 4 slides.

  The caliper 4 is supported by the mounting member 3 so as to be movable in the disc axis direction by a slide pin 12 and a slide shaft portion (not shown) of the dual-purpose pin 13 and is a so-called pin slide type caliper. . The caliper 4 has a caliper body 25, a hanger pin 26, and a piston (not shown).

  The caliper body 25 is attached to the slide shaft 12 (not shown) of the dual-purpose pin 13 of the mounting member 3 and the slide pin 12 so as to be movable in the disk axis direction, straddling the disk 2. The caliper body 25 includes a cylinder part 31 disposed on the outer side of the bracket 11, a bridge part 32 extending from the outer side of the cylinder part 31 in the disk radial direction to the inner side of the disk 2, and a bridge It has a claw portion 33 extending radially inward of the disk 2 so as to face the cylinder portion 31 from the inner end portion of the portion 32. In other words, the caliper body 25 is provided with the cylinder part 31 and the claw part 33 so as to face the bridge part 32 arranged across the disk 2 with the disk 2 interposed therebetween.

  The cylinder portion 31 has a sliding guide portion 35 formed on the inner side in the disk radial direction, and a sliding guide portion 36 formed on the outer side in the disk radial direction. The slide pin 12 is slidably fitted to the sliding guide portion 35, and the slide shaft portion (not shown) of the dual-purpose pin 13 is slidably fitted to the sliding guide portion 36. In these sliding guide portions 35 and 36, the caliper body 25 is slidably supported by the slide pin 12 of the mounting member 3 and a slide shaft portion (not shown). Here, a portion of the slide shaft portion (not shown) between the slide guide portion 36 and the bracket 11 is covered with the boot 7. A piston (not shown) is fitted to the cylinder portion 31 so as to be slidable in the disk axial direction.

  The cylinder portion 31 is formed with a pin support portion 40 that protrudes on the opposite side to the sliding guide portion 36 in the disk rotation direction. The pin support portion that protrudes on the same side as the pin support portion 40 is also formed on the claw portion 33. A portion 41 is formed. The pin support portion 40 is provided on the outer side of the disk 2, and the pin support portion 41 is provided on the inner side of the disk 2.

  The hanger pin 26 is inserted through the pin support portion 40 and the pin support portion 41 and extends so as to connect the pin support portion 40 and the pin support portion 41 in this inserted state. The hanger pin 26 extends along the disk axial direction and is disposed so as to straddle the disk 2 on the outer side in the disk radial direction than the disk 2.

  Outer pad 5 of pads 5 and 6 is disposed between the outer surface of disk 2 and a piston (not shown), and is a lining that abuts against disk 2 and generates frictional resistance. 45 and this lining 45 is attached to one surface, and has a back plate 46 that receives a pressing force from a piston (not shown) on the other surface. The back plate 46 is formed with a small hole 47 on one side in the disk rotation direction and a large hole 48 larger than the small hole 47 on the other side in the disk rotation direction. In the outer side pad 5, the torque receiving shaft portion 22 of the dual-purpose pin 13 of the mounting member 3 is inserted into the large hole 48, and the hanger pin 26 of the caliper 4 is inserted into the small hole 47. The pin 26 is supported so as to be movable in the disk axial direction.

  The inner side pad 6 is disposed between the other surface of the disk 2 and the claw portion 33, has a mirror-symmetric shape with respect to the outer side pad 5, and is in contact with the disk 2. It has a lining 50 that generates frictional resistance, and a back plate 51 that is adhered to one side and receives the pressing force from the claw portion 33 on the other side. A small hole 52 shown in FIG. 2 is formed on the back plate 51 on one side in the disk rotation direction, and a large hole 53 shown in FIG. 1 larger than the small hole 52 is formed on the other side in the disk rotation direction. The pad 6 on the inner side has a large hole 53 in which the torque receiving shaft portion 22 of the dual-purpose pin 13 of the mounting member 3 is inserted, and the hanger pin 26 of the caliper 4 is inserted in the small hole 52 shown in FIG. The pin 13 and the hanger pin 26 are supported so as to be movable in the disk axial direction.

  When the brake fluid is introduced into the cylinder part 31 shown in FIG. 1, the caliper 4 moves forward in the direction of the disk 2 with respect to the cylinder part 31 with a piston (not shown), and one of the pair of pads 5, 6 The pad 5 is pressed toward the disk 2. Then, the outer side pad 5 comes into contact with one surface of the disk 2, and the reaction force causes the caliper body 25 to move the sliding guide portions 35 and 36 between the slide pin 12 of the mounting member 3 and the both-purpose pins 13. The cylinder portion 31 is moved in a direction away from the disk 2 while sliding with respect to a slide shaft portion (not shown). Then, the claw portion 33 brings the other pad 6 into contact with the other surface of the disk 2. In this way, the caliper 4 brakes the rotation of the disk 2, that is, the wheel, by pressing the pads 5 and 6 against the disk 2 from both sides by a piston (not shown) and the claw portion 33. Accordingly, the pair of pads 5 and 6 are movably provided on the attachment member 3 and the caliper 4, and are pressed against both surfaces of the disk 2 by the caliper 4.

  As shown in FIG. 2, the outer side pin support portion 40 includes, in order from the outer side, a screw hole 61, an intermediate hole 62 having a diameter equal to or smaller than the thread diameter of the screw hole 61, and a small-diameter hole having a smaller diameter than the intermediate hole 62. 63 is provided. In the inner side pin support portion 41, in order from the outer side, an intermediate diameter hole 65 having the same diameter as the small diameter hole 63, a pin insertion hole 66 having a smaller diameter than the intermediate diameter hole 65, and a larger diameter than the intermediate diameter hole 65 are provided. A diameter hole 67 is provided.

  The hanger pin 26 includes, in order from one side in the axial direction, a hexagonal columnar tool engaging portion 71, a screw shaft portion 72, a cylindrical large-diameter shaft portion 73 having an outer diameter equal to or smaller than the thread valley diameter of the screw shaft portion 72, and a large diameter. A cylindrical intermediate diameter shaft portion 74 having an outer diameter smaller than the outer diameter of the diameter shaft portion 73, a substantially cylindrical small diameter shaft portion 75 having an outer diameter smaller than the outer diameter of the intermediate diameter shaft portion 74, and a small diameter shaft portion. A protruding portion 76 having an outer diameter larger than the outer diameter of the small-diameter shaft portion 75 that protrudes from 75 toward the outer side in the radial direction is formed. The outer diameter of the protrusion 76 is smaller than the hole diameter of the intermediate diameter hole 65 and larger than the hole diameter of the pin insertion hole 66 in a state where a radial external force (reaction force described later) is not applied. ing.

  The protrusion 76 is formed in a substantially spherical shape. That is, the protruding portion 76 is a hemispherical portion 76B (tip-side reduced diameter portion) that smoothly decreases in diameter from the maximum outer diameter portion 76A of the protruding portion 76 indicated by a two-dot chain line in FIGS. The hemispherical portion 76C (base-end-side reduced diameter portion) smoothly reduces the diameter from the maximum outer diameter portion 76A toward the small-diameter shaft portion 75 side (base-end side). As shown in FIGS. 2 and 3, the small-diameter shaft portion 75 and the protruding portion 76 are provided with slits 81 that penetrate these in the axial direction of the hanger pin 26. The slits 81 are provided at four positions with a 90-degree pitch in the circumferential direction of the hanger pin 26, and these slits 81 intersect on the central axis of the hanger pin 26. By forming these slits 81, the small diameter shaft portion 75 and the protruding portion 76 are divided into four divided portions 82 in the circumferential direction of the hanger pin 26. The four divided portions 82 are provided at a pitch of 90 degrees in the circumferential direction of the hanger pin 26, and each extend in the axial direction of the hanger pin 26. Each of the four divided parts 82 includes a shaft part constituting part 83 constituting the small diameter shaft part 75 and a projecting part constituting part 84 constituting the projecting part 76. The hanger pin 26 is formed from one metal material.

  When attaching the pads 5 and 6 for the state shown in FIG. 2 to the caliper 4, the hanger pin 26 is attached to the pin support portions 40 and 41 of the caliper body 25 with the protruding portion 76 in the axial direction at the head. The pin support portion 40 is inserted from the screw hole 61 side. At that time, the protrusion 76 of the hanger pin 26 has a screw hole 61, an intermediate hole 62, a small diameter hole 63, a small hole 47 in the outer pad 5, a small hole 52 in the inner pad 6, and a pin support portion. It inserts in this order in the intermediate diameter hole 65 of 41.

  Thereafter, the screw shaft portion 72 can be screwed into the screw hole 61, and when the screw shaft portion 72 is screwed into the screw hole 61, the protruding portion 76 is connected to the intermediate diameter hole 65 and the pin insertion hole 66 of the pin support portion 41. 4 is in contact with the tapered step 90 shown in FIG. 4 and receives a reaction force from the step 90. Since the slit 81 is formed in the small-diameter shaft portion 75 and the projecting portion 76, the four projecting portion constituting portions 84 constituting the projecting portion 76 are converted into the four shaft portion constituting portions 83 by the reaction force from the stepped portion 90. Are close to each other while being elastically deformed toward each other. As a result, the protrusion 76 is reduced in diameter and passes through the pin insertion hole 66. When the projecting portion 76 passes through the pin insertion hole 66, the reaction force from the pin support portion 41 disappears, and the diameter of the projecting portion 76 increases due to the return of elastic deformation of the four shaft portion constituting portions 83. Return to the diameter state. Thereafter, the hanger pin 26 is tightened with a predetermined tightening torque to be in a fixed state in which it is fixed to the caliper body 25 as shown in FIG. At this time, the projecting portion 76 is disposed apart from the stepped portion 92 that is an opening on the outer side of the pin insertion hole 66 in the axial direction, and in detail, is spaced apart by a distance indicated by H in FIG. Thus, the caliper body 25 is not in contact with the caliper body 25. For this reason, the vibration during traveling of the vehicle from the caliper 4 is not transmitted on the front end side of the hanger pin 26, and the looseness of the screw shaft portion 72 of the hanger pin 26 is suppressed.

  When the hanger pin 26 is in this fixed state, the screw shaft portion 72 on one end side is screwed into the screw hole 61, the large diameter shaft portion 73 is disposed in the intermediate hole 62, and the intermediate diameter shaft portion 74 is the small diameter hole. 63 and the intermediate diameter hole 65, the small-diameter shaft portion 75 on the other end side is inserted into the pin insertion hole 66, and a part of the small-diameter shaft portion 75 on the protruding portion 76 side and the entire protruding portion 76 are pin insertion holes. Projecting to the opposite side of the screw hole 61 from 66. In this fixed state, the projecting portion 91 projecting from the pin insertion hole 66 on the other end side of the hanger pin 26 has a projecting portion 76 projecting radially outward of the hanger pin 26 and the axial direction of the hanger pin 26. And a slit 81 penetrating the protrusion 76. Further, in this fixed state, the outer diameter of the protruding portion 76 of the hanger pin 26 is larger than the pin insertion hole 66 into which the small-diameter shaft portion 75 is inserted. Thereby, even if the screw shaft portion 72 is loosely engaged with the screw hole 61, the hanger pin 26 moves in the axial direction with respect to the caliper body 25, so that the protrusion 76 has a hemispherical shape. Since the portion 76 </ b> C (base-end-side reduced diameter portion) abuts on the stepped portion 92 that is the opening on the outer side of the pin insertion hole 66, the hanger pin 26 is restricted from being removed from the caliper body 25. For this reason, even if looseness occurs in the screw fitting of the hanger pin 26, the pair of pads 5 and 6 can be continuously supported by the caliper body 25.

Here, as shown in FIG. 5, the maximum outer diameter of the protruding portion 76 is B, the width of the slit 81 is C, and the center of the slit 81 on the base end side (the base end of bending of the divided portion 82) O is The distance to the maximum outer diameter portion is D, the distance from the center O of the slit 81 to the tip of the hanger pin 26 is E, the deflection amount of the maximum outer diameter portion of the protrusion 76 is F, the diameter of the pin insertion hole 66 Is G and the bending angle of the dividing portion 82 is θ, the following dimensional relationship is satisfied in order for the protruding portion 76 to pass through the pin insertion hole 66.
tan θ = (C / 2) / E
tan θ = (F / 2) / D
Therefore, F = 2 × D × tan θ
Since the deflection amount F of the maximum outer diameter portion of the protruding portion 76 is larger than the tightening allowance, F> B−G

  Since the disc brake described in Patent Document 1 has a structure in which an elastic member is mounted on the hanger pin, the number of parts increases and the number of assembly steps also increases.

  On the other hand, the hanger pin 26 of the disc brake 1 according to the embodiment is screwed into the screw hole 61 provided on the caliper body 25 at one end side and inserted into the pin insertion hole 66 provided on the caliper body 25 at the other end side. The protruding portion 91 protruding from the pin insertion hole 66 on the other end side includes a protruding portion 76 and a slit 81 protruding outward in the radial direction of the hanger pin 26. Thus, when the hanger pin 26 is screwed into the caliper body 25, one end of the hanger pin 26 is screwed into the caliper body 25, and the protrusion 76 on the other end is inserted into the pin insertion hole 66 of the caliper body 25. The caliper body 25 is fixed to the caliper body 25 so as to protrude outward in the radial direction from the pin insertion hole 66 outside the caliper body 25.

  Therefore, it is not necessary to configure the hanger pin 26 with a plurality of parts for assembling to the caliper body 25, and the hanger pin 26 can be made into one part. In addition, when assembling the hanger pin to the caliper body, when assembling a plurality of parts, it is not necessary to perform a post-assembling check operation, thereby facilitating process assurance.

Moreover, since the hanger pin 26 does not have a structure having an elastic member, the hanger pin 26 can be prevented from being deteriorated with time and worn due to vibration, and the durability of the hanger pin 26 can be improved.
Further, a hemispherical portion 76C (base-end-side reduced-diameter portion) that is smoothly reduced in diameter toward the small-diameter shaft portion 75 side is formed on the small-diameter shaft portion 75 side from the maximum outer diameter portion 76A of the protruding portion 76. Therefore, when replacing the pair of pads 5 and 6, it is relatively easy to unscrew the hanger pin 26 and remove it from the caliper body 25.

  Note that the protrusion 76 is brought into contact with the step 92 shown in FIG. 4 between the pin insertion hole 66 and the large-diameter hole 67 with the hanger pin 26 fixed to the caliper body 25 with a predetermined tightening torque. In such a case, since the rigidity of the protruding portion 91 of the hanger pin 26 is improved by providing the protruding portion 76, the relative vibration of the hanger pin 26 with respect to the caliper body 25 that occurs during the vibration of the vehicle body can be suppressed. Further, vibration resistance can be improved, and abnormal noise caused by the hanger pin 26 can be suppressed.

  Here, the hanger pin 26 can be changed as follows.

  Of the four divided portions 82 constituting the small-diameter shaft portion 75 and the protruding portion 76, two adjacent portions in the circumferential direction of the hanger pin 26 are eliminated as shown in FIG. 6, and only two divided portions 82 are provided. Also good. Alternatively, two of the four divided portions 82 that are not adjacent to each other in the circumferential direction of the hanger pin 26 may be eliminated as shown in FIG. 7, and only two divided portions 82 may be provided.

  Further, the number of slits 81 is not limited to four, and at least one slit may be provided. For example, as shown in FIG. 8, three slits 81 may be provided at a pitch of 120 degrees in the circumferential direction of the hanger pin 26, and the number of divided portions 82 may be three.

  Further, as shown in FIG. 9, a plurality of protrusions 76 </ b> A that protrude outward in the radial direction of the hanger pin 26 are provided side by side in the circumferential direction of the hanger pin 26, and the plurality of protrusions 76 </ b> A are arranged therebetween. A slit 81 may be provided. For example, in FIG. 9, six protrusions 76A are provided, and three slits 81 are provided at a pitch of 120 degrees in the circumferential direction of the hanger pin 26 so that the protrusions 76A are disposed two by two.

  As shown in FIGS. 10 and 11, a protrusion 76B having a shorter axial length than that of the hanger pin 26 is provided, and a small diameter shaft 75 is provided on the opposite side of the small diameter shaft 75 of the protrusion 76B. You may provide the small diameter axial part 101 of the same diameter. In other words, the hanger pin 26 may be provided with a protruding portion 76B that forms a band between the small diameter shaft portions 75 and 101 and protrudes radially outward. 10 and 11, four slits 81 are provided at a pitch of 90 degrees in the circumferential direction of the hanger pin 26, but at least one slit may be provided.

  In addition, as shown in FIG. 12, the small-diameter shaft portion 75 and the projecting portion 76 of the hanger pin 26 are provided with one slit 81 penetrating them in the axial direction and the radial direction of the hanger pin 26, and the radial direction of the hanger pin 26. A pair of cut surfaces 111 having a shape in which the protrusions 76 are cut out flat may be provided on both sides of the protrusions 76 where the slits 81 are opened. The pair of cut surfaces 111 are parallel to each other and orthogonal to the radial direction of the hanger pin 26. By forming the slit 81 in this way, the small diameter shaft portion 75 and the protruding portion 76 are divided into two divided portions 82. Each of the two divided portions 82 extends in the axial direction of the hanger pin 26, and each of the two divided portions 82 includes a shaft portion constituting portion 83 constituting the small diameter shaft portion 75 and a protruding portion constituting portion 84 constituting the protruding portion 76. Yes. The maximum outer diameter of the portion where the pair of cut surfaces 111 of the protrusion 76 is not formed is larger than the hole diameter of the pin insertion hole 66, and the distance between the pair of cut surfaces 111 of the protrusion 76 is The diameter is equal to or smaller than the hole diameter of the pin insertion hole 66. When the two divided portions 82 are deformed so as to narrow the slit 81, the maximum outer diameter of the protruding portion 76 is set to be equal to or smaller than the hole diameter of the pin insertion hole 66. With this configuration, only one slit 81 needs to be inserted, so that the cost can be reduced.

  Further, the slit 81 does not necessarily pass through the center of the hanger pin 26 and may be displaced from the center of the hanger pin 26.

  The embodiment includes an attachment member fixed to a non-rotating portion of a vehicle, a caliper body provided on the attachment member so as to be movable in the axial direction of the disk, and provided on the attachment member so as to be movable. A pair of pads pressed on both sides of the disc by a caliper, and a hanger pin disposed on one end side of the pair of pads and movably supporting the pair of pads, the hanger pin having one end The side is screwed into a screw hole provided in the caliper body, the other end is inserted into a pin insertion hole provided in the caliper body, and protrudes from the pin insertion hole on the other end side of the hanger pin. The part which is provided is equipped with the protrusion part which protrudes toward the radial direction outer side of this hanger pin, and the slit which penetrates the said protrusion part in the axial direction of this hanger pin. Thereby, the number of parts of a disc brake can be reduced and the number of assembling steps can be reduced.
