Description

UNITARY WHEEL FOR GROUND SERVICE SUPPORTING EQUIPMENT
DESCRIPTION
1. Background of the Invention
The present invention relates to a unitary wheel for Ground Service Support Equipment (GSE).
Over the time, pneumatic tires have been used for GSE such as airport trailers. GSE are mainly considered as indoor use equipment but there are outdoor use GSE such as vehicles that transport luggage to the airplane and from the airplane to the terminal. Number of vehicles can be categorized as GSE from the Luggage trailer to airplane pullers. These vehicles operate with a heavy weight on them during the movement and therefore when it comes to wheels for GSE they need maximum safety and resistance to bumping on indoor and outdoor roads. One of the main concerns of using solid tires in GSEs is that the solid tire is rather heavy when compared to the conventional pneumatic tires and thereby can withstand punctures and bursts as against the pneumatic tires as solid tires are well-known for its safety. Similarly, one of the other advantages of having a solid tire is that the same does not bump on a flat surface. But conventional pneumatic tires tend to bump on flat surfaces.
The main opposition in using solid tires in GSE is that they possess resistance characteristics over rolling on flat surfaces when compared to pneumatic tires.
At present two types of solid tires are used in the GSE. Those are resilience tires and Press on Band (POB) tires. There are 3 major tread patterns in said solid tires as given in Figure 01 of the drawings.
Lug tread pattern is used for the vehicles that are used in wet and slippery conditions and solid tires with lug tread pattern have excellent traction quality and huge stability.
The solid tires with smooth tread pattern are used in most of the toughest applications. This type of tires reduces vibration and increases driver comfort.
Solid tires with rib tread pattern have comparatively low rolling resistance and thereby guaranteeing low vibration. Another added advantage of having a solid tire with rib pattern is that it gives more comfort to the driver.
Solid tires can be of non-mark or black tires as shown in Figure 02 of the drawings.
Currently available solid tires have rim types as discussed in Figure 03 of the drawings.
None of the tires discussed above have the characteristics of inseparability. That is to say the whole wheel is a combination of a rim and a tire that is separable. Similarly, no solid tires so far used in GSE have been 100% recyclable. In the GSE wheel industry it has been a requirement since long to have a solid tire with an inbuilt rim in it as looking for separate rims for GSE tires has not been an easy task. Also, if the tire is to be formed on a ready-made steel rim, the amount of rubber that has to go into the solid tire is so much and thereby contributing to high production cost. Further, such solid tires with steel rims have other disadvantages such as tire weight and heat buildup. The main issue in using the above identified solid tires in GSE is that, when compared to pneumatic tires, the weight of the solid tire is greater. The steal rim adds on to the weight of the tire (Currently available GSE 4.00-8 tire weighs about 17kg with the steel rim and rubber) and it was a concern in the present invention to replace the steal rim with light weight material.
Considering the given scenario, the main object of the present invention is to provide a solid tire with a ready-made rim in it which has the characteristics of being recycled and further having considered the customer requirements.
2. Summary of the Invention
The invention disclosed herein relates to a unitary wheel for GSE.
The present invention discloses a Unitary Wheel comprising a rim portion, said rim portion being injection molded in a single piece and formed of rigid thermoplastic resin, said rim portion comprising a center bore configured to receive axle hub, an inner band 08, a circumferentially extended outer band 07 that margins the rim portion and provides bonding surface to a tire portion, a nave ring 03 that extends outwardly and radially of said center bore wherein a plurality of holes are circularly positioned that are configured to receive bolts, a plurality of ribs extending outwardly and radially at right angles from the nave ring up to the outer band are positioned both sides of the rim configured to improve flexural rigidity of the structure, and a solid tire portion, said tire portion formed of rubber having a rib tread pattern and the said tire portion is compression molded onto said rim portion in order to form a complete wheel which is being unitary and inseparable without destruction of the whole structure.
The present invention is 100% eco-friendly and recyclable.
The present invention is used in Ground Service Support Equipment.
The rigid thermoplastic resin used to form the rim portion of the present invention is reinforced with glass fibers or with any other active fillers in the quantity from 0% to 70% so as to optimize mold ability, strength, durability and weather resistance.
The tire portion of the present invention is made out of abrasive, low rolling resistance tread rubber compound and additionally the tire is cushioned with soft, heat resistant rubber layer.
The present invention has the characteristics of cost effectiveness, light-weighted, low rolling resistance, favorable thermal and strength characteristics and it does not produce noise when in motion. 3. Detailed Description of the Invention
The present invention discloses a single piece wheel that can be categorized as a solid tire which is puncture free compared to the conventional pneumatic tires. The present invention is therefore introduces a safe tire for GSE.
The object of the present invention is to provide a safer tire for GSE considering the usage of the tire in GSE. Also the present invention is more eco-friendly and can be 100% recyclable.
The problem domain is addressed by the present invention by introducing a unitary wheel comprising of a rim made of thermoplastic material. By increasing the size of the rim it reduces the amount of rubber that is to be used in making the tire so that the total weight of the wheel is reduced when compared to other solid tires with steel rims.
Figure 04 shows a comparison of two solid tires, the present invention and the current solid tire with steel rim. This figure shows the size of the rim made of thermoplastic material and thereby reducing the amount of rubber used in the present invention.
In designing a solid tire for GSE, there are few major factors that have to be taken into consideration. The tire should possess the quality of low rolling resistance and ensure the diver's comfort coupled with self-alignment for GSE trailers. In order to achieve the said qualities focus has to be given to compound formulation design, mixing specification for the compound, tire tread pattern design and tire construction.
The present invention consists of two parts which are the rim or the core and the tire. The rim is injection molded in a single piece of a suitable rigid thermoplastic resin like polyamide, polyimide, polypropylene or similar. Thermoplastic resin can be reinforced with glass fibers or with any other active fillers in the quantity from 0% to 70%. Additionally to that Thermoplastic resin may consist of mineral fillers like talk, kaolin, calcium carbonate or any other non-active fillers with other chemicals taken in the quantity sufficient for optimization of processing and performance characteristics .
Once the rim is manufactured, the tire portion is compression molded onto the rim. The tire is formed of suitable flexible material, preferably rubber. It could be made out of abrasive, low rolling resistance tread rubber compound. Additionally to that tire could be cushioned with soft, heat resistant rubber layer. For the construction of the tire portion, a Sulphured rubber compound is first placed around the already manufactured thermoplastic rim. Thereafter said sulphered rubber compound is cured in compression mold and during curing the same is bonded to the thermoplastic rim in order to construct the complete unitary wheel. Once the manufacturing process is completed, the final product comes as a single piece, which is inseparable without destructing the whole structure. The center bore in the rim provides space for axle hub. Between the inner band 08 and the bore there positioned a naive ring 03. Extending inwardly from the outer band 07 substantially at right angles are the ribs which are spaced radially there around to improve flexural rigidity of the structure. These ribs are positioned both sides of the rim. After wearing the ribbed pattern rubber tread, the rim structure can be fully recycled. The rim can be re-melted and injection molded again at the end of the service life.
