Is the Brake Pedal the Same as the Brake?
1 Answers
The brake pedal is indeed the same as the brake. There is a small pedal connected to the brake lever on the brake, hence it is also referred to as the 'brake pedal,' primarily used for decelerating or stopping the vehicle. Below is additional information on vehicle braking systems: 1. Throttle-Controlled Braking: When deceleration is needed, maintain the vehicle in 3rd gear and fully release the throttle. At this point, the engine tends to idle, creating resistance in the drivetrain that acts on the wheels to achieve deceleration. 2. Exhaust Braking: In high-power diesel engines, there is a butterfly valve at the junction between the exhaust manifold and the exhaust pipe. When the vehicle is in gear, operating an electromagnetic switch closes this valve, causing the engine to 'stall' and thus achieve a braking effect. The valve automatically opens when the throttle is pressed again. This method is structurally simple but can damage the engine. It is commonly used in heavy trucks and large buses. 3. Engine Braking Mechanism: A braking signal slightly opens the exhaust valve without closing it, causing both upward and downward piston movements to be dampened by airflow, generating braking force. This method is compact and non-damaging but is currently not available domestically.
