Sistem Rem Hidrolik, Bagaimana Mekanismenya ?

Summary

This video explains the working mechanism of a car's hydraulic disc brake system. It breaks down the system into three main components: the input, hydraulic, and actuator. The input, activated by the driver, triggers hydraulic pressure, which is transferred to the actuator. The actuator, which utilizes a floating caliper design, applies pressure on the brake pads to create friction with the rotating brake disc, slowing down the vehicle. The video also discusses how vacuum assistance makes braking easier and how hydraulic pressure is evenly distributed to all four wheels for consistent braking performance.

Takeaways

• 😀 The car's braking system uses a central brake system that activates all four wheels simultaneously when the brake pedal is pressed.
• 😀 The braking process involves three main components: input, hydraulic system, and actuator.
• 😀 The input component receives mechanical energy from the driver and initiates the braking process.
• 😀 The hydraulic system transmits energy from the input to the actuator, using brake fluid to ensure equal force distribution to all brakes.
• 😀 The actuator converts hydraulic pressure back into mechanical energy to physically stop the vehicle.
• 😀 The disc brake system uses a rotor (or brake disc) connected to the wheel and a caliper that clamps the brake pads onto the rotor to create friction.
• 😀 The brake pads are made of materials like asbestos to prevent sparking during friction.
• 😀 The caliper in the disc brake system is a floating type, meaning it moves horizontally to ensure equal pressure on both sides of the brake pad.
• 😀 The brake pedal is connected to a long rod, which in turn activates a booster to make the braking feel lighter, thanks to vacuum assistance from the intake manifold.
• 😀 The master cylinder contains a piston that pushes brake fluid, creating hydraulic pressure to apply the same amount of force to all four wheels.
• 😀 The hydraulic system ensures efficient and lossless transmission of braking force by using incompressible fluid, making the system both responsive and powerful.

Q & A

What is the main mechanism behind a car's braking system?

A car's braking system generally uses a central brake system, where one brake pedal activates the brakes on all four wheels. The system relies on hydraulic energy to transfer force from the pedal to the brakes.

How is energy transferred in the braking system?

Energy is transferred in three stages: first, mechanical energy from the driver’s foot on the brake pedal; second, hydraulic energy transmitted through brake fluid; and third, mechanical energy again in the form of physical braking when the actuator engages.

What are the three main components in the braking system?

The three main components are the input component (the brake pedal), the hydraulic component (which transmits force), and the actuator (which converts hydraulic energy back into mechanical braking force).

What is the role of the actuator in the braking system?

The actuator, often in the form of a disc brake system, uses hydraulic pressure to apply the brake pads against the brake disc, generating friction to slow down or stop the vehicle.

How does a disc brake system work?

In a disc brake system, the rotating brake disc is connected to the wheel, and stationary brake pads, housed in a caliper, press against the disc when hydraulic pressure is applied, creating friction to stop the vehicle.

What is a floating caliper, and how does it function?

A floating caliper is a type of caliper that is not fixed but can move horizontally. When the hydraulic piston pushes the inner brake pad against the brake disc, the caliper moves, causing the outer pad to also press against the disc, thus providing even braking force on both sides.

What makes the brake pedal feel light when the car engine is running?

The brake pedal feels lighter when the engine is running because of the vacuum assistance from the intake manifold. The vacuum reduces the pressure in the booster, making it easier to apply force to the brake pedal.

How does the brake booster work in the braking system?

The brake booster uses vacuum from the engine to assist in pressing the brake pedal. It has a diaphragm that, when the engine runs, creates a difference in pressure that helps the driver apply less force to engage the brakes.

What is the role of the hydraulic system in the brake system?

The hydraulic system transmits force from the brake pedal to the brake components at each wheel. It uses brake fluid under pressure, ensuring the force is distributed equally to all four wheels.

How does the master cylinder contribute to the braking system?

The master cylinder contains a piston that pushes brake fluid through the system when the brake pedal is pressed. It is responsible for converting the mechanical energy from the driver’s foot into hydraulic pressure, which is then transmitted to all four wheels.
