FABRICATION OF PNEUMATIC BREAKING SYSTEM
Abstract : The aim is to design and develop a control system based on breaking system of an AIR controlled safely automotive wheel braking system. The control valve which directs the air to the double acting cylinder for breaking control. This braking actions is implemented In our project, we have to apply this braking system in one wheel as a model.
The existing approaches in preventing accidents are: Honda?s idea of ABS (Anti-lock Braking System) which helps the rider get a hassle free braking experience in muddy and watery surfaces by applying a distributed braking and prevents skidding and wheel locking. Volvo is all set to launch its new XC60 SUV which will sport laser assisted braking which will be capable to sense a collision up to 50 mph and apply brakes automatically.
? Need separate air tank
? This brake system is costlier one.
? Addition cost is required to install this system to four wheeler .
The Warning systems in any device are integrated with safety systems designed to warn the user about the potential threat. Such a system monitors the dynamic state of the possible danger in real time by processing information from various sensors. It assesses the potential threat level and decides whether a warning should be issued to the user through auditory and/or visual signals. Most of the accidents can be avoided if proper braking is applied in right time. In our project, the proximity sensors (Sharp IR sensors used in the project) monitor the distance of nearby obstacles from vehicle, and gives signal to the comparator circuit (LM 358) which gives output to the transistor circuit. The transistor circuit output is coupled to the relay, which controls the motor (connected to normally closed switch) and the pneumatic circuit actuator, such as a solenoid valve (connected to normally open switch).
? Brake cost will be less
? Free from wear adjustments
? Less power consumption
? Less skill technicians is sufficient to operate
? Installation is simplified very much
