Description

  The present invention relates to a method of processing a wheel bearing device with a brake rotor, and more particularly to a method of cutting a pad sliding surface of a brake rotor.

  There are two types of wheel bearing devices for automobiles, one for driving wheels and one for non-driving wheels. In any case, in the wheel bearing device, since the run-out of the braking surface, that is, the pad sliding surface during rotation of the brake rotor causes the occurrence of brake judder during braking, high processing is required for each component of the wheel bearing device. High accuracy and high dimensional accuracy are required. However, even if the machining accuracy of each part is increased, the machining error of each part is not only accumulated during the assembly of the wheel bearing device, but also an assembly error occurs. Can not do it.

  In order to eliminate such inconvenience, a wheel bearing device with a brake rotor assembled in a mounted state is mounted on a cutting machine, and the brake rotor is rotated while the wheel bearing device with a brake rotor is supported in the mounted state to pad. A cutting method for cutting the sliding surface has already been proposed (US Pat. No. 6,247,219).

According to the above conventional method, since the pad sliding surface of the brake rotor is cut in the mounted state of the wheel bearing device with the brake rotor, the integration error in which the processing errors of each component are accumulated, the distortion generated when the brake rotor is fixed, etc. Is removed by cutting. Therefore, by assembling the wheel bearing device with brake after completion of cutting into the actual vehicle, the wheel bearing device with brake rotor is restored to the state at the end of cutting, and the runout of the pad sliding surface when the brake rotor rotates is It is extremely small and the brake rotor can be rotated with extremely high accuracy.
US Pat. No. 6,247,219

  The conventional machining method that cuts the pad sliding surface of the brake rotor while the wheel bearing device with the brake rotor is mounted suppresses the runout of the pad sliding surface during rotation of the brake rotor and generates vibration during braking. Brake rotor assembled to the inner member in a state in which the outer member is fixed out of the outer member and the inner member that rotate relative to each other through the rolling element. The pad sliding surface is cut, and the rolling contact surface is deformed by deformation of the rolling element contact surface when a cutting load is applied. As a result, the surface runout accuracy deteriorates accordingly. If it demonstrates with reference to FIG. 9, the outer member 2 of the wheel bearing apparatus 1 with a brake rotor will be hold | maintained with the chuck | zipper apparatus 4, the inner member 6 will be rotated, and the flange surface 2a of the outer member 2 will be used as a reference plane. Then, the pad sliding surfaces 8a and 8b of the brake rotor 8 are turned. For this reason, the accuracy of the bearing itself (axial runout, rigidity, etc.) affects the brake rotor accuracy after processing.

  An object of the present invention is to provide a method capable of cutting a pad sliding surface of a brake rotor of a wheel bearing device with a brake rotor more efficiently and efficiently.

  The present invention comprises an outer member having a vehicle body mounting flange on the outer periphery and two rows of tracks on the inner periphery, a hub wheel having a wheel mounting flange on the outer periphery, and an inner ring disposed in a small diameter portion of the hub wheel. Members, two rows of rolling elements that are interposed between the outer member raceway and the inner member raceway so as to be relatively rotatable, and a brake rotor fixed to a wheel mounting flange of the hub wheel. A method of cutting a pad sliding surface of a brake rotor of a wheel bearing device with a brake rotor, wherein the wheel pilot end surface of the hub wheel is turned with reference to the inner ring abutting surface of the hub wheel, The outer member, the inner member and the rolling element are assembled, the brake rotor is fixed to the hub wheel of the inner member, and the pad sliding surface of the brake rotor is turned with reference to the wheel pilot end surface of the hub wheel. In .

  When turning the wheel pilot end face of the hub wheel, the inner ring abutment surface of the hub wheel as in the first aspect of the invention or the raceway of the hub ring as in the second aspect of the invention is used as a reference.

  The invention of claim 3 comprises an outer member having a vehicle body mounting flange on the outer periphery and two rows of tracks on the inner periphery, a hub wheel having a wheel mounting flange on the outer periphery, and an inner ring disposed in a small diameter portion of the hub wheel. An inner member, two rows of rolling elements that are interposed between the outer member raceway and the inner member raceway so as to be relatively rotatable, and a brake rotor fixed to a wheel mounting flange of the hub wheel Cutting the pad sliding surface of the brake rotor of the wheel bearing device with a brake rotor comprising the hub wheel alone, grinding the outer peripheral surface of the hub wheel on the basis of the wheel pilot end surface of the hub wheel, The outer member, the inner member and the rolling element are assembled, the brake rotor is fixed to the hub wheel of the inner member, and the pad sliding surface of the brake rotor is turned with reference to the wheel pilot end surface of the hub wheel. It is.

  As the chuck position when turning the pad sliding surface of the brake rotor with reference to the wheel pilot end surface of the hub wheel, the wheel pilot outer diameter of the hub wheel (Claim 4), the wheel pilot inner diameter of the hub wheel (Claim 5), Examples of the inner diameter of the serration hole of the hub wheel (Claim 6) and the outer diameter of the hat portion of the brake rotor (Claim 7).

  By turning the pad sliding surface of the brake rotor on the basis of the wheel pilot end surface of the hub wheel, high-accuracy machining that suppresses the runout of the pad sliding surface of the brake rotor without restraining the outer member is possible. It becomes possible. As a specific example, the runout of the pad sliding surface of the brake rotor can be 30 μm or less.

  Therefore, according to the present invention, since the rotational runout of the pad sliding surface of the brake rotor can be made extremely small, the rotational accuracy of the brake rotor in the mounted state is improved and the brake judder is generated during braking. Can be suppressed.

  First, before explaining a processing method, the wheel bearing device with a brake rotor which is the object will be explained.

  An example of a wheel bearing device for a drive wheel is shown in FIG. 3, and a wheel bearing device with a brake rotor in which the wheel bearing device and the brake rotor are integrated is shown in FIG. This wheel bearing device includes an outer member 10 corresponding to a bearing outer ring, an inner member 20 corresponding to a bearing inner ring, and two rows of rolling elements 36 interposed between the outer member 10 and the inner member 20. Is the main component.

  The outer member 10 is provided with a flange for fixing to a vehicle body such as a knuckle, that is, a vehicle body mounting flange 12 on the outer periphery, and two tracks 14 are formed on the inner periphery.

  The inner member 20 includes a hub ring 20A and an inner ring 20B. In the hub wheel 20A, a wheel pilot 22 is formed at an end portion on the outboard side appearing on the left side of FIG. 3, and a small diameter portion 24 is formed at an end portion on the opposite inboard side. A spline (or serration, the same applies hereinafter) hole 26 penetrating in the axial direction is formed in the central portion of the hub wheel 20A. A flange for attaching a wheel, that is, a wheel attachment flange 28 is provided on the outer periphery of the end portion on the outboard side of the hub wheel 20A. A plurality of hub bolts 30 are attached to the wheel mounting flange 28. A track 32 is formed on the outer periphery of the intermediate portion of the hub wheel 20A.

  The inner ring 20B is disposed, for example, by interference fit on the small-diameter portion 24 of the hub wheel 20A, and the end surface of the inner ring 20B is abutted against a surface 25 rising in the radial direction from the small-diameter portion 24. In this sense, the surface 25 is referred to as an inner ring abutting surface. A track 34 is formed on the outer periphery of the inner ring 20B. The track 32 of the hub wheel 20A and the track 34 of the inner ring 20B correspond to the two tracks 14 of the outer member 10. Two rows of rolling elements 36 are movably interposed between the raceway 14 of the outer member 10 and the raceways 32 and 34 of the inner member 20 (hub wheel 20A and inner ring 20B). And the inner member 20 are supported so as to be relatively rotatable.

  Note that seals 38 are attached to both end portions between the opposing surfaces of the outer member 10 and the inner member 20. The seal 38 prevents foreign matter from entering the inside of the bearing and prevents leakage of grease filled in the bearing.

  In the wheel bearing device having the above-described configuration, the vehicle body attachment flange 12 of the outer member 10 is attached to the vehicle body by bolt fastening when assembled to the actual vehicle. Further, a spline shaft provided on the outer joint member of the constant velocity universal joint is inserted into the spline hole 26 of the hub wheel 20A, and a nut is screwed to a screw shaft formed at the tip of the spline shaft and tightened with a standard torque. By preloading the hub wheel 20A and the inner ring 20B in the axial direction, a preload is applied to the bearing. Further, the brake rotor 40 and the wheel of the wheel (not shown) are attached to the hub bolt 30 of the wheel mounting flange 28, and the wheel nut (not shown) is tightened. The wheel is centered by the wheel pilot 22 and the brake rotor 40 is centered by the brake pilot 21.

  Next, the processing method of the pad sliding surfaces 40a and 40b of the brake rotor 40 in the wheel bearing device with a brake rotor will be described. The processing method of the first embodiment includes a first step and a second step. In the first step, the end surface 23 of the wheel pilot 22 of the hub wheel 20A is turned on the basis of the inner ring abutting surface 25 with the hub wheel 20A alone. In the second step, after assembling the bearing and attaching the brake rotor, the outer diameter of the wheel pilot 22 of the hub wheel 20A is chucked, and the pad sliding surfaces 40a, 40b of the brake rotor 40 are set with the wheel pilot end surface 23 as a reference surface. Turning.

  If it demonstrates with reference to FIG. 1, a 1st process is as follows. The hub wheel 20A constituting the inner member 20 of the wheel bearing device is held by the chuck device 42 at the small diameter portion 24. At this time, the chuck device 42 is abutted against the inner ring abutting surface 25. By inserting the spline shaft of the scrape 46 into the spline hole 26 of the hub wheel 20A and rotating the loop 46 as indicated by an arrow, a rotational force is applied so that the hub wheel 20A rotates at the center of rotation of the wheel bearing device. Then, as shown by the white arrow, the cutting tool 44 is fed and the end surface 23 of the wheel pilot 22 is turned with reference to the inner ring abutment surface 25. With this processing, the axial deflection of the end surface 23 of the wheel pilot 22 during rotation of the wheel bearing device can be sufficiently reduced regardless of the dimensional error and assembly error of each member.

  The second process will be described as follows with reference to FIG. The brake rotor 40 is attached to the hub wheel 20A of the wheel bearing device (FIG. 3) that has completed the first step (FIG. 4). The wheel bearing device with the brake rotor thus configured is held by the chuck device 48a at the outer diameter of the wheel pilot 22, as shown in FIG. At this time, the chuck device 48 a is abutted against the end face 23 of the wheel pilot 22. In this state, the spline shaft of the thread 52 is inserted into the spline hole 26 and the inner member 20 is rotated. As shown by the two-dot chain line arrows, the cutting tools 50a and 50b are fed to the pad sliding surface 40a of the brake rotor 40. , 40b.

  According to this embodiment, it is possible to secure the end face 23 of the wheel pilot 22 in which the axial runout accuracy with respect to the rotation of the wheel bearing device in the first step is extremely small, and in the second step, the brake rotor 40 of the brake rotor 40 is used as a reference. Since the pad sliding surfaces 40a and 40b are turned, the axial runout of the pad sliding surfaces 40a and 40b of the brake rotor 40 with respect to the rotation of the wheel bearing device can be extremely reduced.

  Further, distortion generated when the brake rotor 40 is fixed to the wheel mounting flange 28 is also removed. Further, in the conventional method, the outer member 10 is fixed and the pad sliding surfaces 40a and 40b of the brake rotor 40 are cut, so that when the cutting load is applied, the rolling element contact surface is deformed and the bearing rotation axis is changed. In this embodiment, when the pad sliding surfaces 40a and 40b of the brake rotor 40 are machined, there is a phenomenon that the machining axis is shaken, and as a result, the surface runout accuracy is deteriorated. The side member 10 is not constrained, and therefore, the bearing rotation center and the machining axis are less likely to be shaken, and can be machined with high accuracy.

  Regarding the first step, when turning the end surface 23 of the wheel pilot 22 of the hub wheel 20A serving as a reference, the end surface 23 of the wheel pilot 22 is turned with reference to the inner ring abutment surface 25. The end surface 23 of the wheel pilot 22 may be turned on the basis of the track 32.

  Further, when turning the pad sliding surfaces 40a, 40b of the brake rotor 40 in the second step, the hub wheel 20A is held by the chuck device 48a at the outer diameter of the wheel pilot 22, but the hub wheel 20A at this time 2, in addition to the outer diameter of the wheel pilot 22 as shown in FIG. 2, the inner diameter of the wheel pilot 22 (FIG. 5), the inner diameter of the serration hole 26 (FIG. 6), and the outer diameter of the hat rotor of the brake rotor 40 ( FIG. 7) is also possible. More specifically, in FIG. 5, the inner diameter is chucked with the chuck device 48 b in contact with the wheel pilot end face 23. In FIG. 6, the chuck device 48c is brought into contact with the wheel pilot end face 23, and the inner diameter of the serration hole 26 of the hub wheel 20A is chucked by the chuck device 48d. In FIG. 7, the chuck device 48c is applied to the wheel pilot end face 23, and the outer diameter of the hat portion of the brake rotor 40 is chucked by the chuck device 48e.

  In the second embodiment, as shown in FIG. 8, the hub wheel 20A alone is ground on the outer peripheral surface of the hub wheel 20A on the basis of the end face 23 of the wheel pilot 22. In this case, the end face 23 of the wheel pilot 22 is supported by the chuck device 54, and the overall grinding wheel 56 having a contour corresponding to the outer peripheral surface of the hub wheel 20A including at least the track 32, the inner ring abutting surface 25, and the small diameter portion 24 is provided. use.

  The wheel bearing device has been described by way of example for a driving wheel in which a spline hole 26 is formed in the inner member 20 (hub wheel 20A). However, the wheel bearing for the non-driving wheel in which the hub wheel 20A is solid is described. It may be a device.
