Description

Wheel mounting structure for vehicle Technical Field The present invention relates to a technique for mounting a wheel of a vehicle to a hub. Background The vehicle is configured to transmit driving force to tires on its road surface, and therefore, the vehicle includes a structure configured to mount each tire to a wheel and mount the wheel to the vehicle to mount the tire to the vehicle. The wheel is mounted to a hub of the vehicle. For stable power transmission performance and better durability of the vehicle, a firm mounting structure is required between the wheel and the hub. Conventionally, a structure for fixing a wheel to a hub using a plurality of hub bolts and a plurality of wheel nuts is widely used. This structure provides a very strong coupling and high durability. However, the wheel mounting structure using the plurality of hub bolts and the plurality of wheel nuts has disadvantages in that the time taken to replace the wheel is relatively long and the appearance of the wheel mounting structure is somewhat poor. With the recent popularity of high performance vehicles and the development of racing sports, there is a need for further shortening the time to replace the wheels and for a more aesthetically pleasing wheel appearance. The information included in the background of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art that is known to a person skilled in the art. Disclosure of Invention Various aspects of the present invention are directed to providing a wheel mounting structure for a vehicle configured to greatly shorten a wheel replacement time and effectively prevent theft of a wheel, while contributing to the formation of an aesthetically pleasing wheel appearance. The objects of the present invention are not limited to the above objects, and other objects of the present invention which have not been described will be more clearly understood by those skilled in the art from the following detailed description. In accordance with one aspect of the present invention, the above and other objects can be accomplished by the provision of a wheel mounting structure for a vehicle, including a hub, a wheel fitted around a center boss of the hub at an inner diameter portion of the wheel, a center locking bolt coupled to the center boss and configured to press the inner diameter portion of the wheel against a hub flange of the hub, and a locker installed between the center locking bolt and the center boss and configured to lock the center locking bolt in the center boss. The shackle may release the locked state of the center locking bolt by pressure applied to the shackle by the center locking bolt. The shackle may be mounted at the central boss so as to be linearly slidable in the axial direction while preventing rotation, and may be supported by the hub while being elastically supported in the axial direction against the central locking bolt. The latching teeth may be formed at facing surfaces of the latch and the center locking bolt to allow the center locking bolt to rotate in a fastening direction of the center locking bolt to the center boss while preventing the center locking bolt from rotating in a direction opposite to the fastening direction. A spring seat may be provided at the hub. A spring may be mounted between the spring seat and the shackle to resiliently support the shackle against the center locking bolt. A hub cavity may be formed at the hub to reduce the mass of the hub. The spring seat may be supported by a snap ring (snap ring) mounted between the hub cavity and the central boss. A snap spring (circlip) may be mounted at the hub to prevent the latch, which is resiliently supported by the spring, from separating from the hub. A compression ring comprising a wedge-shaped cross section may be provided between the head flange of the centre-lock bolt and the wheel to press the wheel against the hub flange. The wedge-shaped cross section of the pressure ring may include an inclined ring surface formed to be inclined with respect to the axial direction to contact the wheel, an inner circumferential ring surface configured to surround the center boss of the hub, and a bolt facing surface formed perpendicular to the axial direction such that the bolt facing surface faces the head flange of the center locking bolt. A friction reducing washer may be located between the bolt facing surface of the compression ring and the head flange of the center lock bolt to reduce friction between the bolt facing surface and the head flange. At least one friction reducing groove may be formed at the head flange facing the friction reducing gasket to reduce the area of contact of the head flange with the friction reducing gasket. A sealing ring may be provided at the circumferential surface of the head flange of the center locking bolt to form
