Description

Assembly and retention structure of foam wheel

technical field

The utility model relates to an assembling and retaining structure of foam wheels applied to vehicles such as sandy beach vehicles or load carts.

Background technique

At present, general ATVs or trucks and other vehicles, in order to enable them to bear a large load, mainly use foam wheels. The structure of the foam wheels is to cover a foam wheel on the outer edge of the frame. However, due to its heavy load, it is easy to cause the foamed wheel body to slide relative to the wheel frame and be separated and damaged when driving.

Therefore, in order to prevent the displacement of the wheel frame and the foamed wheel body, as shown in the patent case No. 560446, which was announced in Taiwan, China on November 1, 2003, the name is "the wheel frame structure of the hollow foamed wheel". The inner edge of the foam wheel body has an inner flange that is opposite and forms an accommodating space, and the two sides of the foam wheel body are covered with two opposite wheel frames and the outer edge has an outer flange surface, and the outer flange surface is inner. Pointed protrusions are arranged, and the surrounding surface of the flange end on the inner side of the wheel frame is protruded with distribution protrusions, and then ring-shaped stoppers are arranged in the accommodation space between the two inner flanges of the foam wheel body , and the inner edge of each stop body is provided with a flange part that can extend below the inner flange part of the foam wheel and has a convex part on the outside, so that each convex part is just staggered to extend to each convex part of the flange end of the wheel frame Therefore, when the two opposite wheel frames are fastened and moved inward, the inner flange of the foam wheel body is tightly clamped between the flange surface of the wheel frame and the stop body, and the foam wheel The outer side of the body is pierced and positioned by the sharp protrusions on the outer flange of the wheel frame, so that the hollow foam wheel body can truly exert a better elastic buffer effect after being fixed.

And as shown in the patent case No. M255139 of the new No. M255139 title of Chinese Taiwan announcement on January 11, 2005 " the improvement of the strengthening structure of hollow foam wheel ", it is in the wheel body of a hollow shape foam wheel, coated with The wheel center is arranged in a ring shape with multiple sections, so that the wheel body still has the elasticity of outward expansion, and a number of pointed parts are uniformly distributed on the concave surface of the rim, and then each section is pre-loaded into the hollow hairpin. Then put the wheel body and the wheel center on the rim of the wheel frame, and then make the protruding points penetrate into the wheel body, so that the wheel body is positioned, so that the gap between the wheel frame and the wheel body can be prevented. Slip, and at the same time, because the hollow wheel body is covered with the wheel center, the foam wheel can bear heavier weight pressure.

However, in the above-mentioned prior patents, the wheel frame and the foamed wheel body are consolidated by using the pointed body or the pointed part, so as to achieve the effect of preventing relative displacement and slipping. In high-speed driving conditions, it is easy to break due to the excessive relative shear force generated by the wheel frame and the foamed wheel body, so the use effect is not good.

Utility model content

The purpose of the utility model is to provide an assembly and fixing structure of the foam wheel, which can avoid the relative sliding between the wheel body and the wheel frame or the wheel cover during driving and cause separation and damage, and prolong the service life.

In order to achieve the above object, the solution of the present utility model is:

An assembly and retention structure of a foam wheel, comprising:

A round frame, which is provided with a plurality of ribs, and through holes are formed between the ribs;

The wheel body is covered on the rib plate of the wheel frame, the wheel body is provided with a through hole, and a first fixing part is correspondingly formed on the periphery of the through hole of the wheel body, and the first fixing part There are multiple first fixing holes;

Two wheel covers, which are relatively fixed on the wheel frame. The wheel covers are respectively provided with a positioning hole, and a positioning screw is pierced in each of the positioning holes, and each of the positioning screws is screwed and locked with a positioning nut. , the periphery of the wheel cover is respectively provided with a second fixing portion, and the second fixing portion is provided with a plurality of second fixing holes corresponding to the first fixing holes;

At least one fixing element is fixed in the corresponding first fixing hole and the second fixing hole.

The fixing element is a bolt, and is screwed together to fix a fixing nut.

After adopting the above structure, the utility model has the following advantages:

1. The assembly and fixing structure of the foam wheel of the present invention uses fixing elements to fix the wheel body on the wheel frame and the wheel cover, which can avoid the relative sliding between the wheel body and the wheel frame or the wheel cover during driving, resulting in separation and damage, extending the its service life.

2. The assembly and fixing structure of the foam wheel of this utility model can increase the load of the wheel body and improve its carrying capacity.
