How to master the braking force of the locomotive when the freight train is commonly braked Details

Summary. Hello, the braking rate of the pro-bike is calculated as follows:

1. Axle braking rate = the sum of the maximum braking force of the left and right wheels of the coaxial wheel, 100% of the static axle load of the axle;

2. The braking rate of the whole vehicle = the sum of the maximum braking force of each wheel and the sum of the static axle load of each axle 100%;

3. Parking braking rate = 100% of the sum of the static axle load of each axle of the parking braking force.

The ratio of the common braking force to the emergency braking force of the train.

Hello, the calculation method of the braking rate of the pro-scooter is as follows: 1. Axle braking rate = the sum of the maximum braking force of the left and right wheels of the coaxial axle 100% of the static axle load; 2. The braking rate of the whole vehicle = the sum of the maximum braking force of each wheel and the sum of the static axle load of each axle 100%; 3. Parking braking rate = 100% of the sum of the static axle load of each axle of the parking braking force. Simplify and defile.

If my answer is helpful to you, please also help my little sister to give a like (in the lower left corner of the evaluation), looking forward to your praise of the brigade, your vertical efforts are very important to me, and your support is also the driving force for my progress. Finally, I wish you good health and a good mood!

Answer]: The first paragraph of the Safety Regulations for Metal and Non-metallic Mines (GB 16423) mentions that the speed of train operation shall be determined by the mine, but it shall be guaranteed to be able to stop within the braking distance of 300m of the quasi-gauge railway, narrow gear or rail railway.

The braking method generally used by China's railway wagons is (Brother Cave) AElectric braking.

b.Tread braking.

c.The disc is old and withered.

d.Magnetic rail braking.

Correct Answer: B

The parameter used to express the braking capability of a train is the train conversion braking rate. ()

Hello, the train braking rate refers to the ratio of the sum of the brake shoe pressure of the locomotive and all vehicles in the train to the total weight of the train. It is often used as the basis for calculating the braking distance of the train. Trains must have the minimum braking rate necessary to ensure safe driving.

China's "Railway Technical Management Regulations" stipulates that for freight trains, the calculated braking distance is 800m, and the phosphorus cast iron brake shoe is used, and the converted brake shoe pressure per 100 tons of train weight shall not be less than 280kN; For passenger trains, the braking distance calculated by the nuclear mega is 800m, and the pressure of the converted brake shoes per 100 tons of train weight shall not be less than 580kN; For passenger trains using disc brakes, the calculated braking distance is 1100m and 1400m, and the converted brake shoe pressure per 100 tons of train weight shall not be less than 320kN. <>

Hello, long waiting! The braking rate of the train refers to the ratio of the sum of the brake shoe pressure of the locomotive and all vehicles in the train to the total weight of the train. It is often used as the basis for calculating the braking distance of the train.

Trains must have the minimum braking rate necessary to ensure safe driving. China's "Regulations for the Modification of the Technical Management of the Covered Hu Sedan Railway" stipulates that the calculated braking distance of the freight train is 800m, and the phosphorus cast iron brake shoe is used, and the converted brake shoe pressure per 100 tons of train weight shall not be less than 280kN; For passenger trains, the calculated braking distance is 800m, and the pressure of the converted brake shoes per 100 tons of train weight shall not be less than 580kn; For passenger trains using disc brakes, if the braking distance is calculated to be 1100m and 1400m, the pressure of the converted brake shoe per 100 tons of train weight shall not be less than 320kN

The braking system is generally composed of two main parts: the brake control mechanism and the brake. The braking control mechanism produces the braking action, controls the braking effect, and transmits the braking energy to the various parts of the braking system of the brake, and the brake generates the part that beats the force that hinders the movement or movement trend of the vehicle.

1.The brake pedal of the car is under the steering wheel, and when the brake pedal is pressed, the brake lever is pressurized and transmitted to the brake pad on the brake drum to jam the brake wheel, so that the car slows down or stops running. The manual brake of the car is next to the gear shift and is connected to the brake bar.

Bicycle brakes are also common, which are decelerated by rod brakes fixed to the frame or disc brakes.

2.The brakes are accomplished by the intense friction between the brake pads and the brake drums.

3.The principle of braking is to convert the kinetic energy of the car into heat energy and consume it, and the kinetic energy comes from the power provided by the engine, which needs to be provided by the work of fuel combustion, which means that if you step on the brakes once, it means that your gasoline will be wasted. So, please remember the first point:

When driving, apply the brakes as little as possible, and braking is only for comfort or in an emergency.

4.Many brakes are emergency brakes as a last resort, so you must pay attention to the braking skills. There are two situations discussed here, one is the vehicle without the ABS anti-lock braking system, and the old vehicles are basically like this.

This kind of vehicle in the encounter with emergency Ji Wei Kai brakes, if the braking force is too large, it may make the car tires lock (the tires do not rotate at all), we can often see two long black brake marks on the road, this is the trace of friction between the tire and the ground when the car brakes without ABS, the tire will no longer rotate after the tire is locked due to emergency braking, but the huge inertia will make the tire of the car rub against the ground and continue to slide forward, The violent friction between the tire and the ground caused a black mark on the rubber particles that had been rubbed off on the tire. At this time, if you force the direction, it will often have serious consequences such as deviation, side slippage, tail flicking, or even rollover out of control.
