Explain worlemg of hydraulic brakes using Pascal's low
Answers
Answer:
Working of Hydraulic Brakes
Explanation:
The brakes which are actuated by the hydraulic pressure (pressure of fluid) are called hydraulic brakes. Hydraulic brakes are commonly used in automobiles. Principle Hydraulic brakes work on the principle of Pascal’s law which states that “pressure at a point in a fluid is equal in all directions in space”. According to this law when pressure is applied on fluid it travels equally in all directions so that uniform braking action is applied on all four wheels.
When the brake pedal is pressed, the force is transmitted to the brake shoes through a liquid (link). The pedal force is multiplied and transmitted to all brake shoes by a force transmission system. The system of a hydraulic brake of a four-wheeled automobile consists of a master cylinder, four-wheel cylinders, and pipes carrying a brake fluid from the master cylinder to a wheel cylinder.
When the brake pedal is pressed to apply the brakes, the piston in the master cylinder forces the brake fluid. This increases the pressure of the fluid. This pressure is transmitted in all the pipes and up to all-wheel cylinders according to Pascal’s law. This increased pressure forces out the two pistons in the wheel cylinders. These pistons are connected to brake shoes. So, the brake shoes expand out against brake drums. Due to friction between brake linings and drums, wheels slow down and brakes are applied.
Explanation:
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
