Advantages And Disadvantages Of Electromagnetic Brakes

Electric vehicles (EV) are one of the cleanest and most environmentally friendly cars available at this point in time. By definition, an electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable or another energy storage device. The electric motors used in these cars gives off instant torque, creating strong and smooth acceleration. Some of the models of EVs have an electric motor for each wheel. Having these four motors not only allows for better propulsion, but also for the use of braking and changing the kinetic energy back into chemical energy in the batteries. The traction that the car gets is also increased with each wheel driving. In some of the EV models the electric motors can be mounted directly inside the mounting for the wheel, which enables a loss of all the moving parts between the motor and the wheel. When there is no axle, differential, or transmission, the EVs have less drivetrain

As its main function is to reduce the friction, and providing bearing support, its conceivable failure is detected by testing during maintenance. the probability of failure is either wearing off the rolling element, or misalignment of bearing which is a result of failure of bearing spacer. The system effect due to this is difficulty in cornering the vehicle, harsh

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 development and use of the disk brakes was fist in England in the 1980’s. Frederick William Lanchaster was the first guy that patented the first ever caliper-type disk brake in his Birmingham factory in 1902 and it was used successfully on his Lanchaster cars. He struggled to keep up the maintenance of a quality brake because of the limited choice of metals in the period of time. Causing him to use copper as the braking medium acting on the disk. However, due to the bad road conditions, it didn’t allow copper to last very long because copper can wear out easily, making the disk brake system non-viable.

Abstract—In this modern era, many advancements in technology have been witnessed. Research and data collected around the world have allowed for these advancements to take place. This has allowed for a better understanding of the footprint humans leave on the environment. As a result, this has allowed for the planet to become eco-friendlier. An eco-friendly advancement in the 21st century is the electric vehicle. There are a plethora of benefits using electric vehicles. Some advantages include no emissions, cost-effective, and low maintenance.

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

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

Trim brakes are section of brakes which adjust the train speed during the ride instead of bring the train to a complete stop. Block brakes are section on any coaster wherever more than one train is also running, prevents collision between the two or more trains running on the track acting as a virtual barrier. Skid brakes are a long piece of material, often built with ceramic located in the middle of the train and the track, when the break is activated the skid raises and produces friction against the train. Fin brakes are a metal fin attached to the underside of the train connected with two computer-controlled squeezing mechanism to slow or stop the train. Magnetic brakes are new technology gadget for roller coasters beginning to gain popularity because of their high safety, instead of using friction to stop the train uses completely magnetic and resistance properties. The breaks slowing a train via friction can often be affected by different elements such as

Brembo brakes which offer excellent stopping power, and in my opinion is one of the best brake companies in the world.

The Z07 Performance Package includes Brembo carbon ceramic-matrix brake rotors that improve braking performance and contribute to greater treatment through truncated un-sprung weight.

This is a research assignment on the Physics of Car Crashes. In this report the physics behind car crashes will be reported on in depth to answer the question, “In a car crash, are you better to trust the science behind a more modern vehicle, or the metal in a large, heavy, older car?” This report will explain the Physics behind why Modern vehicles are safer than older cars in a car crash.

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.
