The disclosure relates to a wheel securing structure of trucks. More particularly, an easy structure design is used to let the aluminum 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 and rims, and then tires are assembled on the rims. Accordingly, when the drive shaft is rotated to drive the wheels to move the vehicles forward.
Iron rims are mainly used in traditional vehicles. However, the weight of the iron rims is heavier. Therefore, more energy is consumed when the vehicles advance. The heat dissipation of the iron rims is also poorer to cause the tires to be blown out easily. Moreover, the iron rims easily rust. Therefore, wheel covers are used to cover the iron rims to increase the aesthetics of the vehicles. In light of the many drawbacks of the iron rims, practitioners research and develop aluminum rims. The aluminum rims are light weighted to save the energy when the vehicles advance. The heat dissipation of the aluminum rims is excellent to prevent the tires from being blown out. Moreover, the surfaces of the aluminum rims can be polished and electroplated to have a bright and beautiful look. The wheel covers are thus no longer needed. Therefore, the aluminum rims are commonly adopted by common vehicles.
However, heavy vehicles, including trucks, combination trucks, and container trucks, still use iron 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 wheels with better rigidity are used.
Therefore, in view of the present aluminum 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.
This invention is related to a truck's securing structure. The main purpose is to provide an easy and convenient structure design for a securing structure of aluminum rims suitable used by trucks and other heavy vehicles.
For reaching the purpose above, a truck's securing structure is provided. The securing structure mainly comprises an aluminum rim. The aluminum rim comprises a mounting part, a rim part formed on a periphery of the mounting part, a receiving space formed by the mounting part and the rim part, and plural keyholes disposed on a central periphery of the mounting part; an assembling part having an axial connection part and received by the receiving space of the rim, as well as plural blots disposed on a central periphery of the assembling part and penetrating the keyholes of the mounting part of the rim; and plural nuts secured onto the bolts correspondingly. The truck's securing structure is characterized in the followings.
Plural iron screwshaft liners have a cylindrical shape and sleeve-connected to the keyholes of the mounting part of the rim respectively to tightly match the screwshaft liners and the keyholes. The bolts penetrate the holes of the screwshaft liners, and a length of the screwshaft liners is longer than a length of the keyholes to let two ends of the screwshaft liners each extend out of the keyholes. Conical pits are formed on two terminal surfaces of the mounting part and positioned to respectively correspond to the keyholes. Two ends of the screwshaft liners each are 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, 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 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 rim will not be directly rubbed by the bolts, nuts, and the assemble part to thus damaged. Accordingly, the aluminum rim can be suitable for the trucks and other heavy vehicles.
The inventors have tested the aluminum rims in trucks when the trucks advance. As shown in
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
Plural iron screwshaft liners 4 have a cylindrical shape and sleeve-connected to the keyholes 14 of the mounting part 11 of the rim 1 respectively to tightly match the screwshaft liners 4 and the keyholes 14. The bolts 22 penetrate the holes 41 of the screwshaft liners 4, a length of the screwshaft liners 4 is longer than a length of the keyholes 14 to let two ends of the screwshaft liners 4 each extend out of the keyholes 14. Conical pits 15 are formed on two terminal surfaces of the mounting part 11 and respectively correspond to the keyholes 14. Two ends of the screwshaft liners 4 are folded to form a first folded edge 42 and a second folded edge 43 to respectively insert into the conical pits 26 on two terminal surfaces. The rim 1, the assembling parts 2, and the nuts 3 are secured and positioned.
The nuts 3 are against the first folded edge 42 to be positioned. The terminal surface of the assembling part 2 is against the second folded edge 43 to be positioned.
Please refer to
A truck's wheel drive shafts are rotated to drive the rims 1 with the tires through the assembling parts 1 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 parts 2, bolts 22, and 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, the friction at the contact rubbing sites of the nuts 3 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 liner 4. Accordingly, the soft aluminum rim will not be directly rubbed by the bolts 22, nuts 3, and the assemble part 2 and thus not be damaged. Accordingly, the aluminum 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 securing structure of the truck's rims uses a screwshaft liner to strengthen the structural strength of the contact sites between the aluminum rims and blots, as well as the nuts and the assembling parts. Therefore, the aluminum rims having advantages of light weight, oil saving, good heat dissipation, and aesthetics also can be used in trucks and other heavy vehicles.
2. The truck's wheel securing structure uses a simple and easy screwshaft liner to solve the problem of the aluminum rims being not capable of being used in trucks and other heavy vehicles. Especially, the easy structure facilitates the assembling and practicing without adding too much cost, and thus the securing structure can be mass produced.
