Standard features

A comparative analysis of the "Safety Technical Conditions for Special School Bus Schools" (GB24407-2009) and the relevant requirements for the safety technical requirements of ordinary passenger cars. The National Standard for Special School Bus GB24407-2012 "Safety Technical Conditions for Special School Buses " mainly has the following characteristics:

( A ) subdivided school bus types. The standard divides special school buses into child-only school buses, school-only school buses, and school buses for primary and secondary school students. It also stipulates that the three types of school buses are for preschool children, primary school students, and nine-year compulsory education students ( primary and middle school students) over 3 years of age. Health), in line with the "school safety management regulations car" in transporting children, students should use the provisions of special school bus, but also give full consideration to the possibility of learning at school-age children nine-year rural areas use with a dedicated school bus, in favor of To ensure the safety of students going to and from school while increasing the use of special school buses.

(C) set crash safety structure. Taking into account the fact that China’s road traffic is complex, mixed traffic phenomena are common, and frontal collisions are frequent in traffic accidents, in order to improve the safety of occupants in frontal collisions on special school buses, the standard specifies that the front of dedicated school buses should be equipped with collision safety structures. In the case of a front transverse engine, the centerline of the crankshaft of the engine should be located before the frontmost point of the front windshield ; if it is a front longitudinal engine, the centerline of the first cylinder and the second cylinder of the engine should be located before the frontmost point of the front windshield. ; if medium-sized dedicated bus (refer to the vehicle longer than six meters or less dedicated bus 12 meters) in the front crash performance of not less than the first two structures, the engine arrangement may not be defined. At the same time, in order to reduce the risk, the standard stipulates the maximum number of occupants for private school buses. Specifically, the number of child-only school buses shall not exceed 45. The school bus for primary school students and the school bus for primary and middle school students shall not exceed 56 persons.

Large and medium-sized private school buses should be body frame structures. The top beams, columns and main beams of the same cross-section should form closed rings ( except wheel covers and top windscreens ) , from the side windows to the longitudinal beams between the bottom beams The column should adopt the integral structure, and the middle shall not be connected by fitting welding. If the light dedicated bus (refer to the vehicle longer than 5 m and less than or equal to 6 m private bus) body structure is not above structure, the structure of the cover should be used together with the reinforcing beam carried. The design of the top and upper structure of the special school bus should ensure that the special school bus can pass the top structural strength test and the superstructure strength test. The private school bus should have only one passenger door and be located between the right and the left front wheels. The left and right sides of the vehicle and the front and rear halves and the rear of the passenger zone should each have at least one outlet. Special school buses should be equipped with front and rear bumpers, and at least one first aid box must be installed and installed.

( g ) Strengthen fire safety.
