WHEEL SECURING STRUCTURE OF TRUCKS

Abstract

This invention is related to a wheel securing structure of trucks. The securing structure mainly install iron screwshaft liners on keyholes of the mounting parts of the aluminum rims. The bolts of the assembling part correspondingly penetrate the holes of the screwshaft liners each. 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 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 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 rim will not be directly rubbed by the bolts, nuts, and the assemble part to be damaged. Accordingly, the aluminum rim can be suitable for the trucks and other heavy vehicles.

DETAILED DESCRIPTION

[0016] The inventors have tested the aluminum rims in trucks when the trucks advance. As shown in FIG. 4, the damaged parts of the aluminum rim 5 were mainly focused on the keyholes 51 penetrated by bolts 6, as well as the terminal surfaces compelled by nuts 7. The main reason is that when the steel bolts 6 and nuts 7 contact and rub the aluminum rim 5, the keyholes 51 and the terminal surface of the soft aluminum rim 5 are easily expanded and deformed. Other parts of the aluminum rim 5 were not damaged. Therefore, the structure of the aluminum rims 5 contacted by the nuts and bolts can be strengthened to be used by trucks and other heavy vehicles.

[0017] 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.

[0018] First, please refer to FIG. 1, which shows the truck's securing structure of this invention mainly having a rim 1. 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 keyholes 14 are disposed on a central periphery of the mounting part 11. An assembling part 2 has an axial connection part 21 secured and connected to a wheel drive shaft. The assembling part 3 is disposed in a receiving space 13 of the wheel 1. Plural blots 22 are disposed on a central periphery of the assembling part 2 and penetrating the keyholes 14 of the mounting part 11 of the rim 1. Plural nuts 3 to respectively secure on the bolts 22 correspondingly. The truck's securing structure is characterized in the followings.

[0019] 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.

[0020] 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.

[0021] 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 aluminum rim 1 pre-installed with a tire. Before assembling the wheel 1 and the assembling part 2, several screwshaft liner 4 are sleeved in the keyholes 14 of the mounting part 11 of the wheel 1 one by one to form a tightly matched assembly with the keyholes 14. Subsequently, the first folded edge 42 and the second folded edge 43 are formed by using a fixture punching on the two extending terminals projecting from the keyholes 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 11. The rim 1 assembled with the screwshaft liner 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 liner 4, and the assembling part 2 is positioned in the receiving part 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. Plural nuts 3 penetrate the holes 41 of the screwshaft liner 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 secure the wheel 1 and the assembling part 2.

[0022] 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.

[0023] From the structure and embodiments, it can be known that this invention has the following advantages.

[0024] 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.

[0025] 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.
