How to distinguish an EMU bogie from a trailer bogie

The bogie of the motor car is a traction motor, gearbox and other driving mechanisms, which generally use wheel disc braking, that is, the brake disc is installed on the wheel.

The trailer bogie does not have a driving mechanism, and the axle disc brake is used, that is, the brake disc is installed on the axle.

It is impossible for this thing to be made public, and if it is made public, there is no need to ask, CSR will definitely bear the responsibility of "leaking trade secrets", violating the agreement signed with Kawasaki. Japan's Kawasaki Corporation, which transferred its technology to CSR, will take it to court.

The bullet car bogie is braked with a wheel disc, that is, the brake disc is mounted on the wheel, and the trailer bogie is braked with an axle disc, that is, the brake disc is mounted on the axle.

This is a trade secret, if you send it out here casually, it will cause trouble, you must know that CRH1 China has no independent intellectual property rights.

Give me one if you have one. Red envelope thanks.

The full name of bullet train is power vehicle, which refers to the vehicle equipped with power unit in the rail transit system, including two categories: locomotive and power carriage.

It is a trailer and a corresponding undriven vehicle.

For a train to run properly on the tracks, it must have a bullet train that provides enough traction for the entire train, but without trailers that are not powered. There are bullet trains for all types of trains, including ordinary speed EMUs, normal speed trains, metro trains, light rail trains, monorails, and maglev trains.

The full name of EMU is power vehicle, which refers to the vehicle equipped with power unit in the rail transit system.

The full name of wrecker is road wrecker, also known as trailer, road rescue vehicle, towing vehicle, with lifting, pulling and lifting traction and other functions, wrecker is mainly used for road failure vehicles, urban illegal vehicles and emergency rescue.

The EMU is equipped with drive wheels, and for the train to operate normally on the track, it is necessary to have an EMU to provide sufficient traction for the whole train, but it can not hang an unpowered trailer. The EMU is a railway vehicle with wheel-driven machinery and equipment, not an EMU. There are not only bullet trains in high-speed trains, but also bullet trains in all types of trains, including normal speed EMUs, ordinary speed trains, subway trains, light rail trains, monorail trains, and maglev trains.

An EMU is a car that can walk on its own with its own power, and a trailer is a car that has no power and needs to be dragged by external force to walk. You are right, the form of drag-move-move-drag is the meaning of the middle two bullet train carriages driving and dragging the carriages without power on both sides to walk together.

Japan is the largest in the proportion of using bullet trains, accounting for 87%; The Netherlands and the United Kingdom followed with 83% and 61% respectively; A powered vehicle is called a motor vehicle, and an unpowered vehicle is called a trailer. Germany was the first to manufacture and use bullet trains.

So-called. The first and second class seats are divided into 4 and 5 seats in a row, that is, the first class seats.

and the aisle is slightly wider. In the WC, it's just a toilet (toilet). The other first-class seat can be rotated, so that friends can easily pass by and sit facing each other.

Specifically, first class seats are 4 seats in a row, and the space between seats in each row is wider; The second-class seats are 5 seats in a row, and the second-class seats have a narrower spacing between the front and back than the first-class seats. There is also a large gap in ticket prices.

We know that high-speed rail is divided into first-class and second-class seats, so what is the difference between first-class and second-class seats?

The first is different. The ** of the first-class and second-class seats of the high-speed rail sometimes because of the close distance, it may be twenty or thirty yuan or about 20% more expensive, but if the distance is far, there may be a gap of hundreds of dollars between the two.

The second is that the seats are different. First-class seat number: A and F by the window, C and D by the aisle. Second-class seats: A and F are by the window, C and D are by the aisle, and B is in the middle of the three-seater.

Then there is the difference in the size of the space. There are 4 seats in each row in the 1st class carriage, while 5 seats in the 2nd class are in a row. And the distance between the front and back is also greater than that of a second-class seat.

So in terms of the experience of the ride, the space is not so crowded. In fact, the first class seat is more spaced and the feet can be extended. The backrest of the second-class seat can only be adjusted back a little and cannot be comfortably flattened.

Then there are the different functional facilities. First-class seats are generally equipped with small boards for passengers to put their feet, which is not available in second-class seats. At the same time, the small table in first class is independent, to the right of the seat, while the table in second class is on the back of the chair in front, and if the person in the front seat moves greatly while you are eating, you will also be affected.

Finally, sanitation is different. The first-class toilet is in good condition, has a large space, and is dedicated to the disabled, while the second-class toilet is narrower, but the equipment is complete.

In fact, in addition to the first-class seat, there is also a more comfortable business seat on the high-speed rail. Business seats are not only better than.

The first and second class seats are spacious, but they are still a small enclosed space with only a few seats. There is an electric footrest under the seat, free drinks and snacks on the table, as well as LCD screens and iPads that can be used, and the seat can be completely folded down as a bed to rest, which is completely a separate leisure space. In addition, you can call the flight attendant if you need anything during the ride.

Compared with the second-class seat, the first-class seat is higher, the space is larger, the seat is easier to tilt, and the first-class seat has more complete hardware facilities.

The first class seats and the second class seats are usually in the carriages at both ends of the train (i.e. cars 1 and 8 or 1 and 16), while the second class seats are the seats of other cars.

Secondly, the seats in first class are more spacious than those in second class, with 4 seats per row in first-class carriages and 6 seats per row in second-class seats.

Finally, the service in the first class carriage is more comprehensive and advanced, while the second class is relatively low.

Depending on this model, the CRH1 second-class small square board is located on the back of the front seat and the seat backrest cannot be adjusted, the first-class small square board is on the side of the seat, and the seat back can be adjusted, while the first class seat on other trains is wider than the second class seat as a space and feels more comfortable, but both can adjust the seat back.

The difference between first class and second class is that the first class seat is larger, and the chair should be able to fold down, and the second class seat is the same as a normal train, but it is replaced with a soft seat.

The difference between a first class seat and a second class seat is the space and comfort of the seat, of course, the more expensive the seat, the more comfortable the seat.

The first-class seats are wider and have a large spacing, while the second-class seats are narrow and have a small spacing.

The first-class seat has more space than the second-class seat, the environment is better, the seat is more comfortable, the amount of ** is less, and the ride comfort is better.

Comfort and service, the seats in the first class are spacious, the seats are comfortable, and there are free snacks and drinks, which are not available in the second class.

The head and tail cars of EMUs are generally trailers, but it is not that the head car must be a trailer, or it can be an EMU, for example, in the design process, such as the intermediate car is an EMU, and the head car can also be designed as an EMU when the power is still insufficient (such as the 500-kilometer EMU produced by Sifang Co., Ltd.). Generally, because the head car itself will be relatively long, and the driver's cab of the EMU is at the head, and there are more related equipment, the weight of the head car is generally heavier, and the head car is generally a trailer considering the weight balance of the whole train.

EMU means a powered car, and a trailer is a car that is towed and is not powered. At present, EMUs basically adopt the form of power dispersion, and the first form is 4 moving and 4 dragging, and there are other forms such as 5 moving and 3 dragging. Generally, EMUs can be linked in the form of two EMUs.

The ordinary passenger cars we used to sit in used to be bullet train centralized, that is, there is a locomotive in front, only it has power, and there are many carriages hanging in the back.

All cars have bogies, but there is a difference between the bogies of the bullet car and the trailer, and the bogies of the bullet train are powered.

1.The front of the locomotive and the parking space are all bullet trains, and the bullet train is powered.

2.The bogie is available in every car (including motor cars and trailers)3The EMU bogie has a motor, but the trailer bogie does not have a motor.

4.An EMU is equivalent to a locomotive.

The existing EMUs in China are basically concentrated power EMUs, such as the front and rear of CRH EMUs, which are trailers when rebuilding the connected carriages; A trailer is a non-powered carriage; All carriages are to be fitted with bogies;

The [Central Plains Star] EMU produced by Sifang Factory in China in the 90s is a decentralized EMU, and each carriage has power. Controls are at the front and rear of the car.
