2、a Disc Brake System 文獻、資料來源:Research Journal of Applied Sciences 文獻、資料發(fā)表日期:2012.08.08 院 (部):機電工程學院專 業(yè): 班 級: 姓 名: 學 號: 指導教師: 完成日期: 2against the resistances that oppos

3、e the vehicle’s motion. Relying on these resistances to slow down a vehicle could cause many problems, so an additional resistance called a brake is needed to convert the kinetic energy to heat energy at a faster rate in

4、 order to reduce the speed of the vehicle Mcphee and Johnson (2007). This reduces the speed of the vehicle at a faster rate and brings the vehicle to rest within the shortest possible time when the brakes are applied. F

5、rom the point of view of Johnson et al. (2003) most automotive systems in use today utilize front disc brakes, but four-wheel disc systems are also common In disc brakes, the rotor rotates with the wheel and the pads mov

6、e out to rub the rotor when the brakes are applied. Most disc brakes use floating calipers. The caliper slides in and out as the brakes are applied and released. The piston moves the inside pad out and pushes the outside

7、 pad into the rotor by sliding the caliper back toward the rotor.The use of disc brakes to reduce speed or bring the vehicle to rest when in motion cannot be over emphasized if the safety of the occupant is to be guarant

8、eed Heinz (1999). To bring a vehicle to a stop, the disc brakes have to absorb all the energy given to the vehicle by the engine and that due to the momentum of the vehicle. This energy must then be dissipated. In most v

9、ehicle disc brakes, the energy is absorbed by friction, converted into heat and the heat dissipated to the surrounding air (Thoms, 1988). As the energy is absorbed, the vehicle is slowed down; in other words, its motion

10、is retarded. The brakes must also pull up the vehicle smoothly and in a straight line to bring the vehicle to a stop position. It is therefore very important that the disc brakes of vehicles operate with the highest e

11、fficiency. This could reduce the rate of accidents due to brake failure so that life and property could be preserved and also to ensure that occupants of these commercial vehicles go about their normal lives without any

12、 fear of being involved in an accident. Available crash data in Ghana suggests that about 1,900 persons are killed annually in road traffic crashes (Afukaar et al., 2008) and that more than 40% of the road traffic fatali

13、ties are occupants of cars, buses and trucks. Most often than not, some of the road accidents involving commercial vehicles, such as the mini-buses have been attributed to the failure of the disc brakes. The reason for t
