Abstract

This invention is related to a reinforcing structure of a truck's wheels. The securing structure mainly install iron alloy screwshaft 5 liners on locking holes of the mounting parts of the aluminum alloy or magnesium alloy rims. The bolts of the assembling part correspondingly penetrate the holes of the screwshaft liners. A first folded edge and a second folded edge are formed on two terminals of the screwshaft liners to respectively insert into the conical pits of the 10 mounting part of the rims. The nuts screw onto the bolts of the assembling part to secure the rim onto the assembling part and the nuts. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the rims and the assembling part. Therefore, friction is generated between the wheels and the bolts, as well is as the nuts and the terminal surfaces of the assembling part. The screwshaft liner is used to let the friction above act on the screwshaft liner. Therefore, the soft aluminum alloy or magnesium alloy rims will not be directly rubbed by the bolts, nuts, and the assemble part and thus is damaged. Accordingly, the aluminum alloy or magnesium alloy rims 20 can be suitable for the trucks and other heavy vehicles.

REINFORCING STRUCTURE OF LOCKING HOLES OF TRUCKS’ WHEELS

BACKGROUND

Field of Invention

The disclosure relates to a locking-hole reinforcing structure of a truck’s wheels. More particularly, an easy structure design is used to let aluminum alloy or magnesium alloy rims can be used in trucks and other heavy vehicles.

Description of Related Art

At present, the wheels and drive shafts of vehicles are assembled through rims. Nuts and bolts are used to screw the wheel drive shafts 15 and rims, and then tires are assembled on the rims. Accordingly, the drive shaft is rotated to drive the wheels to move the vehicles forward.

Iron alloy rims are mainly used in traditional vehicles. However, the weight of the iron alloy rims is heavier. Therefore, more energy is consumed when the vehicles advance. The heat dissipation of the iron 20 alloy rims is also poorer to cause the tires to be blown out easily. Moreover, the iron alloy rims easily rust. Therefore, wheel covers are used to cover the iron alloy rims to increase the aesthetics of the vehicles. In light of the many drawbacks of the iron alloy rims, practitioners

The heat dissipation of the aluminum alloy or magnesium alloy rims is excellent to prevent the tires from being blown out. Moreover, the surfaces of the aluminum alloy or magnesium alloy rims can be polished and electroplated to have a bright and beautiful look. The wheel covers are thus no longer needed. Therefore, the aluminum alloy or magnesium alloy rims are commonly adopted by common vehicles.

However, heavy vehicles, including trucks, combination trucks, and container trucks, still use iron alloy rims. The main reason is that the wheel rims of the heavy vehicles are bigger than the wheel rims of the common vehicles. When the heavy vehicles pass bumping roads, the wheel rims withstand greater forces. For increasing the driving safety, iron alloy wheels with better rigidity are used.

Therefore, in view of the present aluminum alloy or magnesium alloy rims having advantages of light weight, oil saving, good heat dissipation, and beautiful appearance but having drawbacks of not being capable of being used by trucks etc., the inventors develop this invention by the many-year manufacturing and design experience and knowledge in the related fields and ingenuity. ο (N S'

^T) σ^ (N O (N O (N diameter of the bolts, and a length of the screwshaft liners is longer than a length of the locking holes to let two ends of the screwshaft liners each extends out of the locking holes. Conical pits are formed on two terminal surfaces of the mounting part and positioned to respectively 5 correspond to the locking holes. Two ends of the screwshaft liners each is folded to form a first folded edge and a second folded edge to respectively insert into the conical pits on two terminal surfaces. The rim, the assembling parts and the nuts are secured.

Accordingly, when the securing structure is assembled to be used, 10 the central axial connection part is secured to the wheel drive shaft of the heavy vehicles including trucks. Therefore, the rim can be driven by the wheel drive shaft through the assembling part to drive the truck move forward. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the rims and the assembling 15 part. Therefore, friction is generated between the wheels and the bolts, as well as the nuts and the terminal surfaces of the assembling part. The screwshaft liners are used to let the friction above act on the screwshaft liners. Therefore, the soft aluminum alloy or magnesium alloy rim will not be directly rubbed by the bolts, the nuts, and the 20 assemble part to thus damaged. Accordingly, the aluminum alloy or magnesium alloy rims can be suitable for the trucks and other heavy vehicles. ο <N δ'

DETAILED DESCRIPTION

The inventors have tested aluminum alloy or magnesium alloy 15 rims in trucks when the trucks advance. As shown in Fig. 5, damaged parts of an aluminum alloy or magnesium alloy rim 5 were mainly focused on locking holes 51 penetrated by bolts 6, as well as the terminal surfaces compelled by nuts 7 or washers. The main reason is that when the harder steel bolts 6 and nuts 7 contact and rub the softer aluminum 20 alloy or magnesium alloy rim 5, the locking holes 51 and the terminal surfaces of the softer aluminum alloy or magnesium alloy rims 5 are easily deformed, and the terminal surfaces of the aluminum or magnesium alloy rims are sunken and broken by the compelling of the r- ο (N S'

in σ^ (N O (N Ό O (N nuts 7 or washers. Other parts of the aluminum alloy or the magnesium alloy rim 5 were not damaged. Therefore, the structure of the aluminum alloy or magnesium alloy rims 5 contacted by the nuts and the bolts can be reinforced to be used by trucks and other heavy vehicles. 5 To more completely and clearly illustrate the technical means and effects of this invention, the detailed descriptions are set forth below. Please refer to the disclosed figures and the reference numbers.

First, please refer to Fig. 1, which shows a locking-hole reinforcing structure of a truck’s wheels of this invention mainly having 10 a rim 1 made from an aluminum alloy or a magnesium alloy. The rim 1 has a mounting part 11 and a rim part 12 formed on a periphery of the mounting part 11. A receiving space 13 is formed by the mounting part 11 and the rim part 12. Plural locking holes 14 are disposed on a central periphery of the mounting part 11. An assembling part 2 has an 15 axial connection part 21 secured and connected to a wheel drive shaft. The assembling part 2 is disposed in a receiving space 13 of the wheel 1. Plural bolts 22 are disposed on a central periphery of the assembling part 2 and penetrating the locking holes 14 of the mounting part 11 of the rim 1. Plural nuts 3 respectively secure on the bolts 22 correspondingly. 20 The locking-hole reinforcing structure of the truck’s wheels is characterized in the followings.

Plural steel screwshaft liners 4 may be made of a material of a low carbon steel, a carbon steel, or a stainless steel. Surfaces of the

σ^ (N O (N Ό O (N screwshaft liners 4 may be hardened and further be knurled or sandblasted to increase the roughness thereof. Please also refer to Fig. 3. The screwshaft liners 4 have a cylindrical shape and sleeve-connected to the locking holes 14 of the mounting part 11 of the 5 rim 1 respectively. The screwshaft liners 4 may match the shape of the locking holes 14 to have a corresponding shape. For example, when the locking holes 14 of the mounting part 11 of the rim 1 are circle, the screwshaft liners 4 are circular cylinders to correspondingly sleeve-connected to the circle locking holes 14, as shown in Fig. 1. 10 When the locking holes 14 of the mounting part 11 of the rim 1 are polygon, the screwshaft liners 4 are polygon cylinders to correspondingly sleeve-connected to the polygon locking holes 14 as shown in Fig. 4. The cylinder body of the screwshaft liners 4 may be straight or have at least a waist. The screwshaft liners 4 tightly match 15 the locking holes 14. Holes 41 of the screwshaft liners 4 are circular to match the outer diameter of the bolts 22 penetrating the holes 41 of the screwshaft liners 4. A length of the screwshaft liners 4 is longer than a length of the locking holes 14 to let two ends of the screwshaft liners 4 each extends out of the locking holes 14. Conical pits 15 are formed on 20 two terminal surfaces of the mounting part 11 and respectively correspond to the locking holes 14. Two ends of the screwshaft liners 4 each is folded to form a first folded edge 42 and a second folded edge 43 to respectively insert into the conical pits 15 on two terminal surfaces.

The rim 1, the assembling parts 2, and the nuts 3 are secured and positioned.

The nuts 3 are directly against the first folded edge 42 to be locked and positioned, or a washer may be placed between the nuts 3 and the 5 first folded edge 42 to lock and position the nuts 3 and the first folded edge 42 through the washer. The terminal surface of the assembling part 2 is against the second folded edge 43 to be locked and positioned, or a washer may be placed between the assembling part 2 and the second folded edge 43 to lock and position the assembling part 2 and the second 10 folded edge 43 through the washer.

Please refer to Figs. 2 and 3 together. When the securing structure is assembled, the axial connection part 21 of the assembling part 2 is securely connected to the wheel drive shaft of the trucks and other heavy vehicles and thus assembled with the rim part 12 of an 15 aluminum alloy or magnesium alloy rim 1 pre-installed with a tire. Before assembling the wheel 1 and the assembling part 2, the several screwshaft liners 4 are sleeved in the locking holes 14 of the mounting part 11 of the wheel 1 one by one to form a tightly matched assembly with the locking holes 14. Subsequently, the first folded edge 42 and 20 the second folded edge 43 are formed by using a fixture punching on the two extending terminals projecting from the locking holes 14. The first folded edge 42 and the second folded edge 43 are correspondingly insert into the conical pits 15 on the two terminal surfaces of the mounting part ο Η Ο (Ν S' (Ν ΙΟ σ^ Η (Ν Ο (Ν Ο (Ν 11. The rim 1 assembled with the screwshaft liners 4 is further assembled with the assembling part 2. The plural bolts 22 of the assembling part 2 are correspondingly penetrate to the holes 41 of the screwshaft liners 4, and the assembling part 2 is positioned in the 5 receiving space 13 of the wheel 1. One terminal surface of the assembling part 2 is against one terminal surface of the mounting part 11 and positioned. The plural nuts 3 penetrate the holes 41 of the screwshaft liners 4 to screw the bolts 22 one by one. The nuts 3 compel another terminal surface of the mounting part 11 and is positioned to 10 secure the wheel 1 and the assembling part 2. A truck’s wheel drive shafts are rotated to drive the rims 1 with the tires through the assembling parts 2 to drive the truck move forward. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the assembling sites of the assembling 15 parts 2, the bolts 22, and the nuts 3. Therefore, friction is generated between the wheels 1 and the assembling parts 2, as well as the nuts 3 and the bolts 22. At this time, the screwshaft liners 4 are used to let the friction between the wheel 1 and the terminal surface of the assembling part 2 mainly act on the second folded edge 43 of the screwshaft liner 4, 20 the friction at the contact rubbing sites of the nuts 3 or the washers mainly act on the first folded edge 42, as well as the friction at the contact rubbing sites of the bolts 22 mainly act on the holes 41 of the screwshaft liners 4. Accordingly, the locking holes 14 of the softer

in σ^ (N O (N O (N aluminum alloy or magnesium alloy rim will not be directly rubbed by the vibrating bolts 22 to deform the diameter of the locking holes 14, and the terminal surfaces of the rim 5 is directly compelled by the assembling part 2, the nuts 7 and the washers to be sunken, broken, or 5 disfigured. Accordingly, the aluminum alloy or magnesium alloy rim 1 can be suitable for the trucks and other heavy vehicles.

From the structure and embodiments, it can be known that this invention has the following advantages. 1. The locking-hole reinforcing structure of the truck’s rims uses a 10 screwshaft liner to reinforce the structural strength of the contact sites between the aluminum alloy or magnesium alloy rims and the bolts, as well as the nuts and the assembling parts. Therefore, the aluminum alloy or magnesium alloy rims having advantages of light weight, oil saving, good heat dissipation, and aesthetics also can be used in trucks 15 and other heavy vehicles. 2. The locking-hole reinforcing structure of the truck’s rims uses a simple and easy screwshaft liner to solve the problem of the aluminum alloy or magnesium alloy rims being not capable of being used in trucks and other heavy vehicles. Especially, the easy structure facilitates the 20 assembling and practicing without adding too much cost, and thus the securing structure can be mass produced. 10
