Classifications & Background of Brake System
Handbrakes used in cars are used to make them stationary and stop the vehicle while it is moving up a slope. Sudden applications of the brake can put the vehicle out of control and lead to skidding. Most of these brakes are hydraulically operated. Classifications of Brake System

Introduction of Braking System
Introduction The continual adjustment of speed in response to the road condition and traffic density ensures the safety of the driver in a ground transport. This requirement can be effectively met by the braking system, the effective design of which completely ensures the vehicle safety and its reliability. An effective braking system should assure a…

Seal Design
O rings are used in hydraulic cylinder sealing due to their effect need shape rectangular section rings are not suited for reciprocating motion and are only in static application; thus secular shaped seal are more preferable for this; we use o type for both static and dynamic seals. Material selection Reasons to select If Di is…

Link Design
The link is connected to the pedal and the base by pin joint. There are two links used to connect the socket and the base. Material selection Where Acr = cross sectional area of the link which must be the least Let us use factor of safety of Then But in practical case the side of the…

Design of Ball
The use of the ball in the hydraulic system is to control the flow of oil out of the cylinder. The ball is pushed by the spring. In order to not go through the spring the ball should have the same or larger diameter than the spring. There is no head to design the ball.…

Design of Pin
Material selection Malleable cast iron with the following material property can be selected as pin Design analysis 2 Pin in the plunger socket joint, Since 130<150Mpa there for the design is safe.

Design of Release Valve
The poppet valve is made tighter to compress the spring and push the ball which pushes fluid out. This valve is against spring force and pressure force. Where, t = human force Fs = spring force Ff = force due to the fluid Consideration, Shear area = 12.7 mm2 Tensile strength area = 14.2 mm2 Material selection Design analysis From…

Design of Pipe
Inside diameter of pipe D = 1.13√Q/V Thickness of pipe Let assume that Q = 40 m3/min V = 2000 m3/min From the weight of the car and diameter of cylinder. We got pressure of 324.8Kpa. From Table 8.2, we find for steel pipe c=3mm there for thickness of the pipe and σt = 40 Mpa Design of Spring Mechanical springs…

Plunger Design
The plunger is the pump cylinder. Material selection is the same material as the main piston which can be used as plunger material. Design analysis Force on the plunger in compression force due to pressure Now to find the plunger lead thickness tpl we use the following equation where tpl = plunger lead thickness d2 = bore diameter of cylinder…
