Three braking methods of motor vehicles

1. The three braking methods of motor vehicles are driving brake, parking brake and engine braking. The following is a specific introduction to motor vehicle braking: driving brake: driving braking is commonly known as "foot brake".

2. Three braking methods of motor vehicles Driving braking, also known as "braking".It is the braking method during the normal operation of the vehicle. The key is to convert the equipment force of the brake plate into liquid working pressure, and then the liquid working pressure is transmitted to the brake and effective to the four tires of the vehicle, thus having the actual effect of braking.

3. The braking methods of automobiles can generally be divided into three types: friction brake, hydraulic brake and electronic brake. The first is friction braking, which slows down the rotation speed of the wheels through friction, so as to achieve the braking effect.

4. Emergency braking. Emergency braking is divided into emergency braking at medium and low speeds and emergency braking at high speed. Emergency braking when driving at medium and low speeds: hold the steering wheel tightly with both hands, quickly step on the clutch pedal, step on the brake pedal almost at the same time, and take the method of stepping to death with one foot to stop the car quickly.

The difference between engine brake and driving brake

1. The deceleration efficiency of driving brake It is higher than engine braking. The engine brakes a slow deceleration process, while driving braking can quickly and effectively achieve the purpose of deceleration braking.

2. DrivingThe difference between braking and engine braking is that driving braking is an active device, while engine braking is an auxiliary braking device. Engine braking is to use the resistance of the engine to slow down the wheels through the gearbox gear connection.

3. The braking environment is different. Driving braking is the braking method when the car is driving normally, while the engine braking method is mostly used under special circumstances. The braking principle is different. The starting brake is transmitted to the hydraulic pressure through the mechanical force of the brake pedal, and then the hydraulic pressure of the brake fluid is transmitted from the pipeline to the brake of the brake disc for braking.

4. Engine braking refers to using engine braking to lift the accelerator pedal without stepping on the clutch. Use the compression resistance, internal friction and intake and exhaust resistance generated by the engine compression stroke to brake the drive wheel.

5. The difference between driving brake and engine brake: driving brake is the normal use of brakes during exercise. Emergency braking is mostly used to deal with emergencies. Step on the clutch pedal and brake pedal at the same time. It can also be used at the same time if it has a handbrake. This kind of brake is more harmful to the vehicle and cannot be used many times in an emergency.

6. Engine braking is an auxiliary device for driving braking. When going down a long slope, the combination of engine braking can effectively improve the efficiency of driving braking, reduce the heating of driving braking parts, and ensure driving safety.

What's wrong with the engine braking? Can the engine also brake?

The so-called "hair"Motive braking" is a term for driving behavior. It refers to the use of the resistance generated during engine operation to effectively control the speed. The two measures of "downshifting" and "loose throttle" can achieve the purpose of using engine resistance to control the speed.

Engine Brake is an auxiliary braking system that can reduce the speed of the vehicle. Unlike traditional braking systems, engine braking consumes the kinetic energy of the vehicle through the compression stroke of the engine, not through brake discs and brake pads.

If the deceleration effect is poor in this process, it means that your engine wear is more serious. In general, we use engine braking to control the speed of the car when it is down a longer slope.

Engine braking, that is, "towing gear" -- the gear is hanging without fuel, and the engine has no traction on the car.On the contrary, because the rotation of the wheels drives the transmission system, the engine at idle has a negative resistance to the car. The higher the gear, the smaller the effect of the engine on the car, and vice versa.
