Recently, besides the “Crash-Responsible†Yutong Company, SAIC, Jinlong, Zhongtong, Chang'an, Ankai and many other domestic bus companies have launched their own school bus products, or optimized the body structure, or equipped with a comprehensive safety monitoring system, or To improve handling, various companies have resorted to the ability to look after their homes, and strive to solve school bus safety issues in a more comprehensive manner.
As of January 17, 2012, just one month later, the "School Car Safety Bill" led by the Legal Affairs Office of the State Council has solicited 7030 public opinions, which shows that the safety of school buses has received much attention from all walks of life.
Let us concentrate on reading and explaining several technical tips to ensure the safety of school buses:
One trick: The "long nose" design eases frontal collisions and protects the safety of drivers and school children;
We know that in a traffic accident, the mortality caused by a frontal collision is the highest. The "long nose" design is equivalent to the buffer zone and deformation energy absorption zone in the frontal collision of the vehicle body, effectively guaranteeing the safety of drivers and schoolchildren. Some school buses are also equipped with two steel bars at the bottom to avoid injury to the car in the event of a frontal impact. At the same time, if a collision occurs, this design structure will ensure that the school bus’s doors will not be able to open due to distortion. Provides viable conditions for the escape of vehicle personnel and the rescue of outsiders.
Trick 2 : Full skeleton connection to ensure the strength of the body and form a unique curve of the safety space in the vehicle;
After trials, the body of the full-frame car body is not easily deformed in the rollover test, and the glass is not easily broken. In the event of an accident, it effectively ensures that the occupants have sufficient safety space in the car, especially if the road conditions are poor. In rural and mountainous areas, this design is crucial. The body of the high floor design also allows the body to be subjected to side impacts, which can effectively protect the safety of students in the car.
Trick 3: The details are considerate, they are happy to go to school and come home safely.
1. A push-pull window is fixed underneath to prevent students from extending their heads and hands out of the window to prevent accidents. In the event of an accident, pupils can also open the windows to escape;
2. It is equipped with a 360° full-view mirror, vehicle condition monitoring system, safety seats and protective plates to prevent students from injuring their rear body monitors when starting or retreating.
3. Install obvious signs such as parking arm and light to ensure the safety of students in getting on and off the train;
4. Limit the speed, prohibit unauthorized adjustment after leaving the factory;
Safety Reminder 1: Tire Wheel Safety Needs Caution
According to the statistics, the total number of traffic accidents in 2009 was 238,000, of which the probability of accidents caused by a puncture was 31.2%. It can be seen that in the past accident cases, the tire hub was a key aspect of safety. As most of the traditional wheels are made of steel materials, they have poor heat dissipation, poor roundness, uneven tire wear, and a large number of traffic accidents are caused by tire overheating due to steel hubs. Safe school buses need to be upgraded. They should use automatic gearbox safety escape windows, school bus stop arms, aluminum alloy wheels, etc.
On this issue, the author made a special consultation with the relevant technical experts of the Wilhelm Bus alloy wheels, experts: aluminum alloy material thermal conductivity is more than three times that of steel, the wheel at high speed, and frequent start and brake process Among them, the high temperature is prone to occur, and tires of rubber material continue to maintain a high temperature, the internal gas expands, and the uneven wear of tires during the driving process makes it easy to cause a puncture accident. At present, in order to reduce the traffic accident caused by this factor, the use rate of aluminum alloy wheels for commercial vehicles in the United States and other countries is nearly 70%.
If school buses can use aluminum alloy wheels that are more energy-efficient, environmentally friendly, and more secure, they will ensure the safety and comfort of school buses.
Safety Reminder II: Safety Awareness Education for Drivers and Passengers
Behind the huge iceberg of school bus problems, the quality and safety awareness of school bus drivers is also one of the issues that deserves our attention. They “carry†a lot of lives and hopes, and should have a high sense of responsibility and professional ethics. They need not only superior driving skills but also a high degree of personal sentiment. Relevant departments should also publish as soon as possible the relevant vocational qualification standards for school bus drivers, as well as special safety awareness training courses. The relevant inspection and supervision mechanisms must also be established and improved so that our school bus safety can be more reliable and parents can More confidence.
