Description

Wheel cap for vehicle having balancing function

The present invention relates to a wheel cap for a vehicle having a balancing function, and more particularly, to a wheel cap configured to maintain the same posture even when a logo or a patterned pattern plate is rotated.

Recently, the interest in the design of the wheel mounted on the wheel of the vehicle has been increased, and wheels of various shapes and materials have been developed. In addition, as shown in FIG. 1, the wheel hub 100 of the vehicle has been increasingly equipped with a wheel cap 100 capable of maintaining a constant posture without rotating the pattern installed therein even when the wheel is rotated.

The wheel cap 100 as described above has an advantage that the logo or the mutual advertising effect is excellent and the refined aesthetic effect can be obtained because the upright state is maintained even while the vehicle is running.

An example of such a conventional non-rotating wheel cap is shown in FIG.

(4) is installed. In addition, the rear of the housing is formed with a plurality of detachable fasteners (7) to be pushed and mounted on the wheel hub of the vehicle wheel.

The wheel cap of the above configuration is installed on the wheel of the vehicle and when the vehicle travels, the housing 6 is coupled to the wheel hub of the wheel so that it rotates together. However, the design plate 1 can be freely rotated with respect to the housing 1 by the bearing 5, and the design plate 1 inside the housing 6 has an eccentric weight 2 installed at a part thereof. The design plate 1 does not rotate despite the rotation of the housing 6 because it is always positioned below. Accordingly, the design plate 1 always maintains the upright posture, and the wheel cap of the wheel can display the upright design even when the vehicle travels.

However, the wheel cap as described above may cause a situation in which the bearing does not operate normally due to corrosion due to moisture, etc., and the design plate 1 for maintaining the posture due to the inflow of manufacturing defects or foreign matters may be The case of rotating with the housing 6 fixed to the wheel has arisen.

Accordingly, the weight body, which is eccentric from the rotating shaft, rotates at a high speed to cause vibration to the vehicle, affects the wheels and the axle, exposes the risk of fatigue destruction, and seriously affects the driving stability.

The present invention has been made to solve the above problems, the present invention is a wheel cap for a vehicle to remove or reduce the eccentric state of vibration or mass generated even if the design plate with a weight (weight) is rotated with the housing To provide.

In order to achieve the above object, the present invention provides a housing in which a main shaft shaft is installed at a central portion thereof, and which can be freely rotated with respect to the housing about the main shaft shaft, so that a center of mass is located at a predetermined distance from the main shaft shaft.

The wheel cap for a vehicle according to the present invention can obtain the effect of promotion and decoration by maintaining a state in which the design plate is always upright. At the same time, the wheel cap for the vehicle of the present invention does not smoothly operate a bearing, so that even if a drawing plate having a weight rotates with the housing, a separate weight balance is performed at a position symmetrical with the drawing plate based on the main shaft shaft. By providing a balancing weight of the vehicle does not cause adverse effects such as vibration during the rotation.

On the other hand, as shown in claim 1 when the design plate including the eccentric weight and the center of mass of the balancing weight is rotated in a symmetrical state with respect to the main shaft shaft, compared to the case where only the design plate is rotated according to the eccentric rotation The vibration state can be greatly improved, and the centrifugal force due to the eccentricity can be detailed by adjusting the mass distribution so that the vibration does not occur or is attenuated.

An embodiment of the present invention will be described in more detail with reference to the drawings.

3 is an exploded perspective view of a vehicle wheel cap according to an embodiment of the present invention, Figure 4 is a cross-sectional view of a vehicle wheel cap according to an embodiment of the present invention.

3 and 4, the vehicle wheel cap according to an embodiment of the present invention is installed so as to freely rotate in the housing 10, the main shaft shaft 20 protrudes in the central shaft shaft 20 A pattern plate 40 having an eccentric weight 42 formed therein, a balancing weight 30 installed so as to rotate freely about the main shaft shaft 20, and a protruding locking protrusion provided at an edge of the eccentric weight 42. (44).

The housing 10 is formed in a circular shape and serves as a main body that supports each component and protects the components installed therein. The rear surface of the housing 10 is attached to the wheel hub fixing plate 50 in which a plurality of detachable fixtures 52 are installed. The housing 10 may be fixed to the wheel hub by pushing the attachment / detachment fixture 52 of the wheel hub fixing plate 50 to the hollow portion formed in the wheel hub of the vehicle wheel.

The inner shaft of the housing 10 is installed so that the main shaft shaft 20 protrudes. Since the main shaft shaft 20 is fixed to the housing 10 by the bearing 17, the main shaft shaft 20 can be freely rotated with respect to the housing 10.

The balancing weight 30 is first mounted on the main shaft shaft 20 protruding from the housing 10.

The balancing weight 30 is a semi-circular plate-shaped body formed with a mounting hole 31 caught in the main shaft shaft 20, and formed of a metal body weight. Therefore, the overall shape of the balancing weight 30 has a circle centered on the main shaft shaft 20 cut in half so that a ring having a mounting hole 31 is formed at the center of the cut portion to form the main shaft shaft 20. It is a hanging structure.

The balancing weight 30 is formed such that the mounting hole 31 is larger than the diameter of the main shaft shaft 20 so as to rotate freely with respect to the main shaft shaft 20. Therefore, the balancing weight 30 may rotate around the main shaft shaft 20 independently of the rotation of the eccentric weight 42 or the design plate 40 which will be described later. Of course, the balancing weight 30 and the spindle shaft 20 may be coupled via a bearing, but the balancing weight 30 forms a mounting hole larger than the diameter of the spindle shaft 20 to reduce the possibility of abnormal operation. It is preferable to simply configure in a state hanging on the main shaft shaft (20).

On the other hand, after the balancing weight 30 is mounted, the pattern plate 40 is stacked on the main shaft shaft (20).

The design plate 40 is configured in the shape of a disk as a whole, the design disk 43 and the design disk 43 is seated on the design disk 41 and is attached to the back of the design case 43 And an eccentric weight 42.

The design disk 41 is preferably formed of a synthetic resin of a light material in a disk shape in which a logo, a trademark, or the like is printed or imprinted.

The design case 43 has a seating space 46 in which the design disk 41 can be seated, and the design disk 41 is fixed. A central hole 45 is formed at the center of the design case 43 so that the end of the main shaft shaft 20 can be inserted therein, and the bearing 47 is inserted into and fixed to the central hole 45 and the main shaft shaft ( The end of 20 is inserted into the bearing 47. Therefore, the design case 43 can be freely rotated with respect to the main shaft shaft (20). The design case 43 is also preferably formed of a light synthetic resin material.

In addition, the bearing 47 is removed between the main shaft shaft 20 and the drawing case 43 and the main shaft shaft 20 is attached to the bearing 17 in a state where the main shaft shaft 20 and the drawing case 43 are fixed to each other. It is also possible to comprise so that it may rotate freely with respect to the housing 10 by this. Moreover, the design case 43 and the design disk 41 can be comprised integrally.

On the other hand, the eccentric weight 42 is fixed to the back of the pattern case 43. The eccentric weight 42 is formed in a semi-circular plate-like body, such as the balancing weight 30, the mass and the center of mass is preferably configured to be the same as the balancing weight (30). The eccentric weight 42 is made of a metal weight in the same manner as the weighting weight 30. Accordingly, the center of mass is located at a predetermined distance away from the main shaft shaft 20.

In addition, in the semi-circular eccentric weight 42, a locking protrusion protrudes from a part, that is, an end, of a corner (X-X-ray of FIG. 5) corresponding to a diameter of the circumferential edge.

As the design plate 40 of the above-described configuration, the eccentric weight 42 is installed, and thus the eccentric weight 42 tries to be positioned under the influence of gravity, so that it can always maintain a predetermined posture.

On the other hand, the front of the housing 10 is equipped with a transparent protective window 60 to protect the components inside and block the inflow of foreign matter.

Next will be described the operation of the vehicle wheel cap according to an embodiment of the present invention.

Figure 5 shows the operation of the balancing weight 30 and the eccentric weight 42 of the wheel cap according to an embodiment of the present invention. The structure and operation shown in FIG. 5 relate to a wheel cap mounted to a right wheel with respect to a driver who is looking at the front of the vehicle.

In FIG. 5, the arrow mark "D", which means the rotation, indicates the rotation direction of the vehicle wheel during driving, and illustrates the operation when the wheel cap is viewed from the outside.

First, as shown in (a) of FIG. 5, the wheel cap according to the embodiment of the present invention has an eccentric weight because the eccentric weight 42 is positioned at a lower portion due to the gravity force G acting at the center of mass during normal operation. The design disk 41 joined with the 42 is not always rotated and maintains the upright posture. The balancing weight 30 is also located at the bottom.

However, during long-term use, the bearing 47 may be damaged or corroded, resulting in manufacturing defects or pinching after the inflow of foreign matter (particularly, between the edge of the design plate 40 and the narrow gap between the inner surface of the housing 10). Due to the pinch), the eccentric weight 42 rotates together with the housing 10. In such a case, the eccentric rotating body continues to rotate about the rotating shaft, and transmits rotational vibration to the axle, which may be exposed to serious dangers during high-speed driving of the vehicle.

Such abnormal operation of the eccentric weight 42 occurs when the eccentric weight 42 is rotated together with the housing 10 fixed to the wheel of the wheel, as shown in FIG. At this time, the balancing weight 30 is able to rotate around the shaft independently of the eccentric weight 42, thereby maintaining the posture at the bottom.

And, as shown in Figure 5 (C), after the eccentric weight 42 is rotated 180 degrees, because the locking projection 44 is caught on the edge of the balancing weight 30, the balancing weight 30 also eccentric weight 42 Will rotate with. In this case, since the eccentric weight 42 and the balancing weight 30 form a disc shape by combining the semicircles, the eccentric weight 42 and the balancing weight 30 can be considered to be the same as when the disc is rotated about the central axis. I never do that. As described above, the respective semicircles are combined to rotate in the shape of disks, and the centers of mass are symmetrical about the main shaft shaft 20. If not, compared to the case in which only the eccentric weight 42 rotates, when the balancing weight 30 rotates symmetrically about the main shaft shaft 20, the vibration generated may be greatly canceled.

For reference, in the above, due to the thickness of the locking protrusion 34, the locking plate 34 is formed on the eccentric weight 42, and the locking protrusion 34 is formed so that the center of gravity of the eccentric weight 42 and the balancing weight 30 is reduced. This is not exactly the same and may cause some differences, but because the thickness and mass of the locking projection 34 is very small, the difference will be negligible.

The following describes the configuration of the locking projection 44 of the wheel cap for a vehicle according to the present invention.

6 (a), the locking protrusion 44 is installed at the right edge of the eccentric weight 42 when the pattern plate 40 is viewed from the rear side, and the right side of the driver is looking forward. The wheel cap installed on the wheel will be described.

Therefore, the wheel cap installed on the left wheel with respect to the driver who watches the front should be provided with a locking protrusion on the left edge of the eccentric weight 42 when the pattern plate 40 is viewed from the rear as shown in FIG. something to do.

As a result, the wheel cap of the present invention consists of a set of wheel caps each of which is provided with a locking projection on one side and the other side with respect to the main shaft shaft 20, it is mounted on the right and left wheels of the vehicle.

The action in the case where the wheel cap constructed as shown in FIG. 6B is provided on the left wheel is shown in FIG. 7.

As shown in (b) of FIG. 7, the eccentric weight 42 rotates along the rotation direction “D” of the wheel, and the balancing weight 30 is independent of the eccentric weight 42 to maintain the posture at the bottom.

As shown in FIG. 7C, when the eccentric weight 42 rotates 180 degrees, the locking protrusion 44 is locked by the balancing weight 30 to rotate together. As a result, the semicircular plate-shaped bodies are joined together, and thus the disc bodies may be rotated about the center thereof, and the eccentricity of the rotating heavy bodies may be removed from the overall viewpoint of the wheel cap.

For reference, the locking protrusion 44 is protruded so as to be caught by the balancing weight 30, and it is not necessarily installed on the eccentric weight 42, even if it is installed to protrude on the rear surface of the design case 43. Can be obtained.

On the other hand, the locking projection 44 may be installed in the balancing weight 30, as well as the eccentric weight 42 or the design case 43.

Fig. 8 shows such a configuration, and the engaging protrusion 34 is formed in the direction of the eccentric weight 42 'at the edge of the balancing weight 30'.

FIG. 8A illustrates a structure of a wheel cap mounted on a right wheel with respect to a driver looking forward, and FIG. 8B illustrates a structure mounted on a wheel located on a left side.

The operation of FIG. 8 (a) can be understood only from the difference in that the installation position of the locking protrusion 34 is changed, and can be understood from the operation shown in FIG. 5, and the operation of FIG. It can be understood from the operation shown in Fig. 7.

For reference, when the vehicle reverses, since the direction of rotation of the wheel is different from that illustrated and described with reference to FIG. 5 or 7, the wheel cap of the present invention does not operate normally. However, the reverse speed of the vehicle is very slow. The reverse distance is also negligible, so the impact of the eccentric mass on the vehicle is negligible.

In addition, the vehicle wheel cap of the present invention can be attached to a steering wheel or the like as well as the wheel of the vehicle.

Although the preferred embodiment of the present invention has been described above, the above embodiment is merely an embodiment within the scope of the technical idea of the present invention, and in the ordinary skill in the art, within the technical idea of the present invention. Of course, other variations are possible.
