BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Strength, Stress distribution capability and the heating of the brake components of a wheel is one of the most common issue in vehicles. Wheels are responsible for carrying the load of a vehicle so, they need to be strengthened and reinforced in order to carry or withstand a heavy load. Due to the excessive use of brakes, the components get heated and thus leads to the defects, malfunction, and poor performance.
[0004] When a driver fails to keep their brakes in good working condition, it could lead to a car accident. According to a report of National Highway Traffic Safety Administration's (NHTSA), roughly 2% of all motor vehicle crashes are caused by vehicular problems such as brake failure or blown tyre etc. There are 5.6 million car crashes in the US every year and it is estimated that the brake failures cause about 5% of them. One of the reasons of car accidents is that the wheels are not capable enough to distribute the load and thus got damaged before time.
[0005] In general, the use of brake system in vehicle leads to the generation of heat due to friction produced by the brake components. This produced heat needs to be dissipated in the environment so that the components of the brake can be kept cooler and efficient.
[0006] For a car wheel, when the disc is pressed, the engagement of engaging parts of the brake component produces heat, which needs to dissipate through the ventilation holes. Further, these holes are responsible for the stress/load distribution that occurs on the rim part of a wheel. The geometric modifications of spokes are sufficient to do so.
[0007] The existing wheel spokes are not capable enough for reducing stress under compressive force exerted on wheel and also, the ventilation holes of the wheel are not sufficient enough to dissipate the heat in order to keep the components cooler. The aesthetic or physical appearance of the existing wheels were not appealing as per the demand of users.
[0008] There exists a need to design a wheel having improved heat dissipation, stress distribution and durability which is fulfilled by the present invention.
