Braking System Essay

The ground trembles as the champ rolls in the shop, so loud the windows start to dance. The threads on the tick black tires are beginning to tear apart and are covered in oil. Engine so blazing hot it hisses angrily at the crew. It’s up to the crew to see what is wrong with her. That’s what an auto mechanic job is, to figure out what is wrong with a car and resolve that problem.

Anti-Lock Brake System (ABS) is a combination of vehicle hardware and software that work together to maintain steering control and vehicle stability during hard braking. Initially developed as a special option for topof-the-line models, today’s ABS units are compact, easy to service, inexpensive and widely available. Now every major automotive manufacturer offers some form of ABS vehicle control that provides safe, maximum braking under all weather conditions and road surfaces.

In this report a comparison of three Braking systems; Calliper, Drum and Disc will be made on a variety of areas including –

The drum break had a main problem and that is that the heat within is not efficiently disbursed. Since the drum prevents wind from drawing it away. The heat produced inside the drum does not easily escape. The disk brake however was open to the wind, allowing the heat to be easily carried away, increasing the efficiency of the break.

In one or more complete sentences, explain how natural laws apply to the following scenarios:

The studies have shown that electric vehicles can reduce greenhouse gas emissions to “6.12 billion tons annually” (Westbrook, 2001). Even though they need mainly coal as a supply of electricity, they produce less harmful emissions than oil, which is the main source of energy for transport modes, driven by gasoline (Westbrook, 2001). With the development of renewable energy technologies that use the power of wind or solar energy, people can get a clean source of electricity, which will make the electric car more friendly to nature. In addition, the introduction of “regenerative braking system” will allow cars to convert the force of inertia into electricity, thus, adding, extra batteries, which, in return, increase its

Most car owners don’t know much about their brakes, except that they stop their car when they step on them. That’s why it’s important to leave car repair and maintenance in the hands of the professionals at Foley Tire & Auto in Foley, AL! Now that it’s winter, you need your car to be safe and reliable, so bring your car into Foley Tire & Auto to get your brakes inspected.

into bettering the efficiency of these cars and trucks. Not only is it the brake

In the recent years, the United States government has been enforcing stricter mandates on auto manufacturers to create safer vehicles, and on construction companies to create safer roadways. Matthew Jensen wrote a dissertation for the Graduate School of Clemson University titled, A Methodology for the Analysis of In-vehicle Operating Data and Design of Intelligent Vehicle Systems for Improved Automotive Safety. In his abstract, Jensen evaluated the future of vehicle manufacturing and traffic-related incidents. Of course, every year more vehicles are manufactured, which in theory means the number of miles driven in vehicles increases. He points out how the World Health Organization (WHO) found that automobile crashes was the ninth

The addition of the Collision Mitigation Braking System™, standard on all but two of the models, makes sure that you stop by delivering brake pressure if sensors detect an obstacle in your path like another car.

I think we can all agree cars are great fun to drive. We also like comparing cars side by side, lining up the specs: horse power, torque ratios, top speed, and especially 0-60 times. One spec, just as important as the rest that is often overlooked is 60 – 0 times, or stopping times. But the fact is that cars must stop. Many of today’s cars do that function using something called Antilock Braking or ABS. ABS uses sensors to monitor the wheel speed in order to determine if a wheel, or multiple wheels, are about to lock up. If the sensors determine this is happening, a series of hydraulic valves limit or reduce the braking on that or those wheels. ABS works on all four tires.

The final part of the braking system is one that is easy to overlook, a lot of people don’t associate with braking at all. The tires. Tires are, as a major brand’s advertisment says, “the only safety feature on the road that actually touches the road.” Stopping the brake rotors, and thus the wheels and tires does little good, and is usually of some detriment if trying to make a controlled stop. This is because when the tires stop moving, or “lock up” their grip on the road changes because the static friction between the tire and the road changed to dynamic friction. The easiest way to imagine this is if you were trying to push a heavy box across the floor. While the box is stationary there is static friction between itself and the floor, once it starts to move it becomes dynamic friction. You might have noticed before if you have ever tried to slide something heavy that it takes more effort to get the object to move initially, than it does to keep it moving. This is because static friction takes more force to overcome than dynamic friction. Similarly, once the tires are sliding on the road, there is less friction, and thus a reduction in braking force relative to the vehicle and the road, not to mention the possibility of spinning out of control. The tires gripping the road is what actually slows the vehicle down and brings it to a controlled

during a skid, braking effectiveness may be reduced to the point of not having brakes at all.

The reason for the development of anti-lock braking system is very simple. Under braking, if one or more of a vehicle’s wheels lock then this has a number of consequences: a) braking distance increases, b) steering control is lost, and c) tire wear will be uncommon. The tangible outcome is that an accident is more likely to occur. The application of brakes creates a force that impedes a vehicles motion by applying a force in the opposite direction. During severe braking scenarios, a point is obtained in which the tangential velocity of the tire surface and the velocity on road surface are not the same such that an optimal slip which corresponds to the maximum friction is obtained. The ABS controller must deal with the brake dynamics and the wheel dynamics as a whole plant.

This report consists of the literature review on the advancement and evolution of braking technology. The report focuses on the need on advancement and the solution found as Eddy current braking. It also explains the working of the eddy current brakes and the advantages and disadvantages of its uses. The scope and the future aspects of eddy current brake systems is discussed in the report.
