Description

  The present invention relates to a brake disc rust prevention wheel cover that covers a decorative hole from the surface side of a wheel in order to prevent moisture from adhering to the brake disc from a decorative hole formed in the wheel disc.

  For example, a wheel mounted on an automobile is generally formed with a plurality of decorative holes along the circumferential direction in order to improve design and heat dissipation of a brake disk. This wheel is attached to the axle of the automobile production line after the tire is assembled. The automobile produced in this way is temporarily stored and transported to the customer until it is delivered to the customer. During such storage or transportation, the automobile is exposed to rain water, air containing moisture, etc., so that the brake disc viewed through the decorative hole of the wheel is likely to rust. In particular, when the ship is transported by sea such as a ferry, salt-containing air directly comes into contact with the brake disk from the decoration hole, and the brake disk is more easily rusted. Such a rusty brake disc can be visually recognized from the decoration hole relatively easily without affecting the brake disc performance, which may impair the customer's identification. For this reason, in recent years, automobile manufacturers attach importance to preventing rusting of brake discs until they are delivered to customers.

  And as a means to prevent such rusting of the brake disc, by attaching a wheel cover from the wheel surface side or sticking a film on the wheel surface, moisture etc. directly from the decorative hole on the brake disc surface Various means for preventing the adhesion have been proposed.

  Here, as a wheel cover mounted from the front surface side of the wheel, for example, as disclosed in Patent Document 1, a configuration of mounting on a wheel by being included in a rim portion of the wheel has been proposed. The wheel cover can cover the entire design surface of the wheel, and can prevent moisture and the like from entering from the decorative hole.

Further, for example, a configuration in which a slit is provided in a disk-shaped wheel cover as in Patent Document 2 has been proposed. This wheel cover covers the entire design surface of the wheel, and even when running with the cover attached, the wind pressure acting inside and outside can be relieved by the slit, preventing it from coming off during transportation Is. The wheel cover is fixed from the front side by a cap that is locked to a hub hole of the wheel, and is attached to the wheel.

  By the way, in the wheel cover for rust-proofing the brake disc, since it is mounted only from the factory shipment to the customer, in addition to being able to exert a sufficient rust-proofing effect Therefore, it is required that the detaching operation is easy and that it is not detached during transportation in the mounted state.

  Here, in the wheel cover of patent document 1, the outer peripheral part is mounted | worn so that it may fit in the inner side part to the rim | limb part of a motor vehicle wheel. For this reason, in order to easily perform the detachment work, it is necessary to form it so that it can be deformed relatively flexibly (low rigidity), and in order to exert a strong holding force, it is difficult to deform (high rigidity). It needs to be formed as a thing. Thus, since the ease of detachment work and making it difficult to come off are contradictory performances, either one cannot be made high performance, and both performances were to be at appropriate levels. . Therefore, this wheel cover ensures a certain degree of ease of detachment work, so the performance for maintaining the wearing state is not sufficient, and it will not come off if it only runs at a low speed, but it runs at a relatively high speed. In such a case, even when the vehicle is traveling at a low speed, it is easy to come off when it receives a relatively large impact by overcoming a step or the like. In particular, when loading on a car carrier or a transport ship, it would be possible to get off because it would overcome various steps. On the other hand, when transporting by sea using a transport ship, depending on the destination, it will continue to be exposed to a hot and humid environment. For this reason, a material having ease of detachment work, such as polypropylene, is likely to be relatively large in thermal deformation, and may be detached from the wheel when it is unloaded from the transport ship.

  On the other hand, the wheel cover disclosed in Patent Document 2 has a problem that a sufficient rust-proofing effect cannot be obtained because air or moisture containing salt passes through the slit. Here, in order to attach this wheel cover, the cap has a configuration including a locking claw that locks in an inner circumferential groove formed in the hub hole. For this reason, at the time of mounting, it is necessary to press this cap so that the locking claw is locked to the inner circumferential groove, and when removing the cap, it is necessary to forcibly pull out the cap outward. Therefore, it is necessary to provide a play allowance to such an extent that the cap can be pulled out, and there is a limit to the holding action when the cap is mounted. For this reason, like the above configuration, there is a concern that it may come off during transportation.

  On the other hand, when a film is attached to the surface of the wheel, when the film is handed over to the customer, the adhesive may remain on the trace after the film has been removed. I need. In addition, since the wheel has a complicated shape for improving mechanical properties and design, the film may be wrinkled or the film may be wrinkled or the film may be torn. If wrinkles or broken parts are generated in this way, moisture may enter from here, so the film attaching operation is extremely difficult.

  The present invention proposes a brake disk rust prevention wheel cover that does not cause the above-mentioned problems, can be easily attached to and detached from the wheel, and does not come off during transportation.

  The present invention includes an engagement hole having a hole diameter equal to or larger than an inner diameter of a hub hole of an automobile wheel at the center, a substantially disc-shaped cover body that covers a design surface of the automobile wheel, and a front surface of the cover body. By being engaged with the hub hole via the engagement hole, the cover body is composed of a cover attachment member that is mounted on the automobile wheel, and when the cover attachment member is engaged with the hub hole, The peripheral edge of the engagement hole of the cover body is supported by an annular flange portion that supports from the front side of the cover body, and is fitted into the hub hole extending from the back surface of the flange portion, and locked in the inner peripheral groove provided in the hub hole. A plurality of locking pieces having locking claws to be engaged, a fitting state in which the locking pieces are locked to the inner peripheral groove of the hub hole, and the locking claws are retracted in the center direction. Engagement / disengagement means that can be operated in either the disengaged state where it is detached from the inner circumferential groove A brake disc antirust wheel cover, characterized in that it comprises a. The front side of the cover body described above indicates the side opposite to the automobile wheel when the cover body is mounted.

  Here, the engagement hole of the cover main body has a diameter equal to or larger than the inner diameter of the hub hole in a range in which the flange portion of the cover mounting member can support the peripheral edge of the engagement hole from the front side. And the structure which makes this hole diameter substantially the same diameter as the internal diameter of a hub hole can be used suitably for an engagement hole. Further, the hole diameter of the engagement hole may be somewhat larger than the inner diameter of the hub hole within the above range.

  In addition, a configuration in which the plurality of locking pieces are extended to the annular flange portion so as to be substantially evenly spaced along the circumferential direction can be suitably used.

  In such a configuration, the cover mounting member for mounting the cover main body to the automobile wheel is such that the locking piece can be operated in either the fitted state or the detached state, and is in the fitted state. Therefore, when the cover body is attached to the wheel, the cover body can be kept attached to the wheel even when traveling at high speed or overcoming a step. obtain. Further, by setting the disengaged state to the state in which the locking piece is retracted from the inner peripheral groove of the hub hole toward the center, it is easy to remove from the hub hole, and the cover body can be easily removed. Therefore, it is excellent in workability of the work of removing the cover main body, and is excellent in holdability for holding the cover main body in a mounted state, so that both can be achieved at a high level. The brake disc rust prevention wheel cover does not come off during transportation, and can prevent the brake disc from rusting before it reaches the customer.

  Here, when the cover mounting member is fitted into the hub hole, the cover is attached to the hub hole after being inserted into the hub hole by the engagement / disengagement operation means. It can be any configuration that is forced to be in a detached state as it is inserted. For example, in the latter configuration, the locking piece extending from the flange portion is formed so as to be in a fitted state in a non-operating state, and the locking claw is centered on the inner peripheral surface of the hub hole. The general shape is retracted in the direction. As a result, as the locking piece is inserted into the hub hole, the locking claw is urged in the center direction, and then the locking claw is fitted into the inner circumferential groove to return to the fitted state and is fitted into the hub hole. . In any configuration, the cover mounting member can be easily fitted into the hub hole. Therefore, the cover mounting member of the present invention is excellent in the work for attaching and detaching the cover main body.

  A wheel made of a light alloy such as an aluminum alloy in an automobile wheel generally has a design center ornament attached to a hub hole when the automobile is delivered to a customer. In addition, an inner peripheral groove for attaching the center ornament is formed. In addition, such an automobile wheel has a design surface formed in accordance with various designs, but there are only a few types of hub holes for each automobile manufacturer regardless of the rim diameter. Since the cover mounting member of the present invention is adapted to fit into the inner peripheral groove of the hub hole, the cover main body can be mounted on most automobile wheels simply by manufacturing one that matches several types of hub holes. can do. And, by manufacturing the cover body according to the rim diameter of the automobile wheel, the brake disk rust prevention wheel cover according to the present invention is relatively small in number for the automobile wheel which is complicated and diversified. It is possible to respond. Therefore, the wheel cover of the present invention only needs to be mass-produced in a small variety, can improve the efficiency of the production process and reduce the manufacturing cost, and has an excellent advantage that it can exhibit sufficient market competitiveness. .

As described above, in the cover mounting member having such a configuration, it is possible to easily perform the operation of mounting and removing the cover body on the vehicle wheel and to sufficiently maintain the mounting state when mounted. The above-described operational effects of the present invention can be appropriately exhibited.

  Here, the structure which connects an operation collar part and the edge part of a locking piece can be used suitably for a connection bone | frame part. This is because when the operating lever portion is pulled, an action of pulling the locking piece toward the center can be greatly generated. As a result, the locking piece can be easily detached, and the operation of removing the cover mounting member is further facilitated.

  In the brake disk rust prevention wheel cover described above, the engagement / disengagement means of the cover mounting member is provided in a disengaged state in which the engagement claw is not engaged with the inner peripheral groove of the hub hole in an unconstrained state. A configuration including an engagement / disengagement operation member that urges the locking piece to the outside by abutting against the inner side surface of the locking piece to lock the locking claw into the inner circumferential groove.

  On the other hand, as described above, in the cover mounting member 3, as the locking pieces 12, 12 are inserted into the hub hole 60, the flange portion 11 is engaged with the peripheral edge 8 of the engagement hole 5 of the cover body 2. The peripheral area of the joint hole 5 is pressed in the reverse direction. And the latching claws 13 and 13 are latched by the inner peripheral groove | channel 62, and the flange part 11 will support the hole peripheral edge 8 of the engagement hole 5 (FIG. 4 (C)). In this way, the cover body 2 is fixed to the hub hole 60 by the cover mounting member 3 at the center portion thereof, and is fixed to the rim flange portion 55a by the outer fitting portion 7 at the outer peripheral portion thereof. Here, as shown in FIG. 4C, the cover body 2 is pressed inward because the peripheral area of the engagement hole 5 is pressed against the hub hole 60 by the cover mounting member 3. It will be deformed and fixed. Thereby, the cover main body 2 exhibits a stronger holding force.

  In this way, the brake disc rust prevention wheel cover 1 is attached, so that it does not come off even when the vehicle is transported at a high speed or over a relatively large level difference. Can be prevented. Also, when transported by sea, it is possible to prevent air containing salt from adhering to the surface of the brake disc. Furthermore, even when stored for a long time in a high-temperature and high-pressure environment during marine transportation, as described above, the cover mounting member 3 is formed of heat-resistant plastics, so that a relatively large thermal deformation occurs. Therefore, the mounting state of the cover main body 2 can be maintained without being detached from the hub hole 60.

  On the other hand, when removing the brake disc rust prevention wheel cover 1 mounted as described above, the operator grasps the handle 16 of the operating collar 14 of the cover mounting member 3 and pulls it in the front direction. The cover attaching member 3 is removed from the hub hole 60. Here, in the cover mounting member 3, when the operating rod part 14 is pulled, the locking claws 13, 13 are retracted in the center direction via the connecting bone part 15 as shown in FIG. Thus, the locking pieces 12 and 12 are in a detached state in which the locking claws 13 and 13 are detached from the inner peripheral groove 62 of the hub hole 60, and the cover mounting member 3 is easily removed from the hub hole 60.

  In this way, the cover body 2 is removed from the automobile wheel 51 by removing the cover attachment member 3 from the hub hole 60.

  As described above, in the brake disk rust prevention wheel cover 1 of the first embodiment, it is easy to attach and detach to the automobile wheel 51, and it is difficult to come off when it is attached.

And a cover mounting member 23 (see FIGS. 7 and 8). The cover mounting member 23 is composed of two members, a mounting main member 22 (FIGS. 6 (C) and 6 (D)) and an engagement / disengagement operation member 27 (FIGS. 6 (A) and 6 (B)).

  Here, as shown in FIGS. 6 (C) and 6 (D), the mounting main member 22 is a locking piece opposed to each other on the annular flange portion 11 that supports the peripheral edge 8 of the engagement hole 5 of the cover body 2. 24 and 24 extend in the reverse direction, and the flange portion 11 and the locking pieces 24 and 24 are integrally formed. Similar to the first embodiment, the locking pieces 24 and 24 are provided at two positions where the circumferential length of the flange portion 11 is substantially divided into two. In addition, the locking claws 13 and 13 that are locked to the inner peripheral groove 62 of the hub hole 60 protrude outward at the distal ends of the locking pieces 24 and 24, respectively, as in the first embodiment. Is provided for each. Here, the locking pieces 24, 24 are provided so that the distance between the locking pieces 24, 24 is substantially equal to the inner diameter of the hub hole 60 and is inclined toward the front end side (back side) toward the center. ing. Then, the distance between the locking claws 13 and 13 is slightly smaller than the inner diameter of the hub hole 60. That is, the locking pieces 24, 24 are in a detached state according to the present invention in a state where they are not restrained by an engaging / disengaging operation member 27 described later, and can be easily inserted into or removed from the hub hole 60 ( (See FIG. 7).

  Moreover, the above-mentioned engagement / disengagement operation member 27 operates the locking pieces 24, 24 of the attachment main member 22 between the fitted state and the detached state as shown in FIG. Here, as shown in FIGS. 6 (a) and 6 (b), the engagement / disengagement operation member 27 has contact portions 29 and 29 that contact the inner side surfaces of the locking pieces 24 and 24 facing the center. Are provided with engaging / disengaging rotation portions 28 provided at two locations in the circumferential direction. In this engagement / disengagement rotation portion 28, a portion between both contact portions 29, 29 along the circumferential direction is a non-contact portion (not shown) that does not contact the locking piece 24. Further, at the center of the engaging / disengaging rotation portion 28, an operating rod portion 31 is projected along the axial direction to the front side. When the operator rotates the operation lever 31, the engagement / disengagement rotation unit 28 is rotated in the circumferential direction, and the circumferential positions of the contact parts 29 and 29 (and the non-contact part) are converted. can do.

  On the other hand, as shown in FIGS. 6 (C) and 6 (D), the above-described locking pieces 24, 24 are formed with locking grooves 26, 26 recessed outwardly on the inner surface of the locking claws 13, 13. ing. As shown in FIG. 8 (a), the engaging grooves 26, 26 are brought into contact with the contact portions 29, 29 of the engagement / disengagement rotating portion 28 of the engagement / disengagement operation member 27. The locking pieces 24 and 24 are urged outward so that 13 is locked in the inner circumferential groove 62 of the hub hole 60. In this way, the locking pieces 24, 24 are in the fitted state of the present invention. Further, portions other than the contact portions 29 and 29 (non-contact portions) of the engagement / disengagement rotating portion 28 are formed to be closer to the center side than the locking grooves 26 and 26 of the locking pieces 24 and 24. ing. Therefore, by rotating the operating rod 31 in the fitted state where the contact portions 29, 29 are in contact with the locking grooves 26, 26, as shown in FIG. , 29 are disengaged from the locking grooves 26, 26, and the urging force of the locking pieces 24, 24 is released to return to the detached state.

  The engagement / disengagement operation member 27 described above is provided in the flange portion 11 of the mounting main member 22 by preventing the contact portions 29, 29 of the engagement / disengagement rotation portion 28 from contacting the locking pieces 24, 24. Can pass through.

  As described above, the cover mounting member 23 according to the second embodiment rotates the engaging / disengaging operation member 27 so that the locking pieces 24 and 24 of the mounting main member 22 are either in the fitted state or the detached state. Can be operated. Therefore, the attachment main member 22 can be easily inserted into or removed from the hub hole 60 in a non-restrained state in which the locking pieces 24, 24 are not biased outward by the engagement / disengagement operation member 27, and the engagement / disengagement is also achieved. When the locking pieces 24, 24 are brought into the fitted state by the operation member 27, the cover mounting member 23 is held in the state fitted in the hub hole 60.

  The handle portion 31 of the engagement / disengagement operation member 27 described above is provided with a handle portion 32 similar to that of the first embodiment.

  In the cover attachment member 23, the attachment main member 22 and the engagement / disengagement operation member 27 are formed of nylon 66 as in the first embodiment.

  Next, the flow of the work of attaching and removing the brake disk rust prevention wheel cover 21 of the second embodiment described above to the automobile wheel 51 will be described.

  The cover body 2 of the brake disc rust prevention wheel cover 21 is fitted to the automobile wheel 51 so as to cover the design surface of the automobile wheel 51 as shown in FIG. Here, the cover body 2 is used for automobiles such that the outer fitting part 7 is fitted on the front rim flange part 55a, and each bolt exposing hole 6 is overlapped with each bolt hole 61 of the automobile wheel 51 in the circumferential direction. The wheel 51 is fitted.

  Thereafter, the cover mounting member 23 is fitted into the hub hole 60 from the front side of the cover body 2 through the engagement hole 5 as shown in FIG.

  For fitting the cover attachment member 23 into the hub hole 60, first, the attachment main member 22 is moved from the front side of the cover body 2 to the engagement claws 13, 13 of the engagement pieces 24, 24 through the engagement holes 5. The hub hole 60 is inserted until the axial position is substantially the same as the inner circumferential groove 62 of the hub hole 60. Here, as the locking pieces 24, 24 are inserted into the hub hole 60, the flange portion 11 presses the hole peripheral edge 8 of the engagement hole 5 of the cover body 2. Thereafter, as shown in FIG. 7 (b), the engaging / disengaging operation member 27 is moved from the front side of the mounting main member 22 so that the contact portions 29, 29 of the engaging / disengaging rotation portion 28 are within the locking pieces 24, 24. Abutting on the side surface, the locking pieces 24, 24 are urged outwardly so as to be pushed backward. Then, as shown in FIGS. 7 (c) and 8 (a), the contact portions 29, 29 of the engaging / disengaging rotation portion 28 are fitted into the locking grooves 26, 26 of the locking pieces 24, 24, respectively. As a result, the locking claws 13 are locked in the inner circumferential groove 62 of the hub hole 60. Thus, the locking pieces 24 and 24 are in the fitted state, and the cover mounting member 23 attaches the cover body 2 to the automobile wheel 51. Here, the engagement / disengagement operation member 27 is in a state where the contact portions 29, 29 of the engagement / disengagement rotation portion 28 are fitted in the engagement grooves 26, 26 of the engagement pieces 24, 24. Does not deviate in the direction. Further, since the locking pieces 24, 24 are urged outward by the engaging / disengaging rotation part 28, the force in the radial direction is balanced, and this fitting state is maintained. Therefore, when the cover main body 2 is mounted on the automobile wheel 51, the cover mounting member 23 does not come off even if the vehicle travels at a high speed or gets over a large step.

  As in the first embodiment, the cover mounting member 23 supports the cover body 2 so as to press the cover main body 2 with the peripheral edge 8 of the engagement hole 5, and the outer fitting portion 7 is attached to the rim flange portion 55a. Since it is supported, it is mounted with a strong holding force. Further, since the cover mounting member 23 is formed of heat-resistant plastics, even when stored for a long time in a high-temperature and high-pressure environment during sea transportation, relatively large thermal deformation may occur. Therefore, the cover body 2 can be kept attached without being detached from the hub hole 60.

  On the other hand, when removing the brake disc rust prevention wheel cover 21 thus mounted, the operator grasps the handle portion 32 of the operation collar portion 31 of the engagement / disengagement operation member 27 and rotates it. As shown in FIG. 8B, the contact portions 29 and 29 of the engagement / disengagement rotation portion 28 are removed from the locking grooves 26 and 26 of the locking pieces 24 and 24. As a result, the locking pieces 24, 24 return to the initial state (disengaged state) in which the locking claws 13, 13 are disengaged from the inner circumferential groove 62 of the hub hole 60 and retracted in the center direction. Then, the mounting main member 22 is removed from the hub hole 60 to the front side, and the cover body 2 is detached from the automobile wheel 51. Here, the mounting main member 22 can be easily removed from the hub hole 60 because the locking pieces 24 and 24 are in the detached state, as in the case of mounting.

  Thus, even in the brake disk rust prevention wheel cover 21 of the second embodiment, as in the first embodiment described above, it is easy to mount and remove from the automobile wheel 51, and when it is mounted. Is held in a mounted state and is extremely difficult to come off. The brake disk rust prevention wheel cover 21 of the second embodiment has the same configuration as that of the above-described first embodiment except that the configuration of the cover mounting member 23 is changed. The explanation is omitted.

  As described above, the brake disc rust prevention wheel covers 1 and 21 according to the first and second embodiments are easy to be attached to the automobile wheel 51, are easy to remove, and are difficult to come off when attached. is there. Therefore, the mounting operation and the detaching operation are easy, and the rust prevention effect on the surface of the brake disc can be surely exhibited without coming off during transportation. In particular, it does not come off even when traveling at high speeds or over large steps, and since it does not come off due to thermal deformation being suppressed even under high-temperature and high-humidity environments during marine transportation, the required rust-preventive effect is sufficiently achieved. It can be demonstrated.

  Further, in the brake disk rust prevention wheel covers 1, 21, the disc-shaped cover body 2 includes the outer fitting portion 7 and has a shape that protrudes to the front side. When mounted, the wheel can be deformed according to the design surface shape of the wheel. For this reason, the cover main body 2 can be mounted with sufficient holding force even on an automobile wheel having various and complicated design surface shapes. Furthermore, the cover mounting members 3 and 23 are formed according to the shape of the hub hole 60 that is available only for each automobile manufacturer, and the cover body 2 is formed according to the rim diameter, so that it can be applied to almost all automobile wheels. It becomes possible. That is, it is only necessary to produce a small number of products as compared with the complicated and diversified automobile wheels, and the productivity and manufacturing cost can be reduced.

  In the first and second embodiments, the cover mounting members 3 and 23 are provided with two locking pieces 12 and 24, respectively. It can also be set as the structure provided individually. By increasing the number of the locking pieces, the stability and retention when mounted are improved. However, if the number is too large, it becomes difficult to operate appropriately and easily in the fitted state and the detached state. Accordingly, a configuration in which about two to six locking pieces are arranged is preferable. In addition, not only the locking pieces extending from the flange portion 11 can be operated in the fitted state and the detached state, but also a predetermined number can be operated, and the rest prevents the cover mounting member from wobbling. Can be. For example, in the same manner as in the first embodiment, the two locking pieces that can be operated are extended, and the two locking pieces that are not connected to the operation collar portion 14 are arranged at substantially equal intervals. Extend to the position. Here, the locking piece that cannot be operated by the operating rod part 14 has a lower effect of locking in the inner circumferential groove than the locking claw of the locking piece that can be operated. By performing a pulling operation, it is difficult to remove from the hub hole.

  The cover mounting member 3 according to the first embodiment described above is formed integrally, but may be formed after each component is formed separately and then joined. Even in the second embodiment, each of the attachment main member 22 and the engagement / disengagement operation member 27 may be formed after the respective components are separately molded and then joined.

  Moreover, in Example 1 and Example 2 mentioned above, although the cover main body 2 shall be shape | molded from polypropylene, what is called general-purpose plastics, such as a polystyrene, is used suitably. On the other hand, the cover mounting members 3 and 23 are molded from nylon 66, but polycarbonate, heat-resistant ABS, or the like can also be used as heat-resistant plastics.

  In the first embodiment and the second embodiment described above, the cover main body 2 is provided with the bolt exposure holes 6 so as to fit the bolt holes 61 of the automobile wheel 51. It can be attached to or removed from the hub 72 of the axle 71 while being attached by the attachment members 3 and 23. Accordingly, the brake disk rust prevention wheel covers 1, 21 can be attached after the tire 76 is attached to the automobile wheel 51 or after being attached to the automobile. Note that the cover main body may be configured such that the bolt exposure hole is not provided.
