JN2070越野四驱货车气压制动系统设计

The Design of Air Brake System about JN2070 off-roadfour-wheel drive truckStudent:Qi ChenAdvisor:Dr.Feng ChengSchool of Mechanical and Automotive EngineeringZhejiang University of Science and TechnologyAbstractAs an important modern land-based transport,Automotive components frommany large parts ,namely,the so-called "assembly"which ensure the performance ofautomotive,and braking system which directly affects the safety of motor vehicles isone of the most important assembly.With the rapid development of highways andincreased traffic density,traffic accidents are also increasing.According to theinformation on the vehicle itself as a result of problems caused by traffic accidents,the brake system failure caused the accident accounting for the total number of 45%.So braking system is an extremely important system to ensure traffic safety.Inaddition,the braking system has a direct impact on the quality of the average vehiclespeed and vehicle transportation efficiency,that is,an important factor ensuringcost-effective transport.It not only can slow down a moving vehicle,but also toensure that the car can be fixed in situ after parking.This shows that the vehiclebraking system plays an important role in traffic safety,the reliability of parking,andtransport economic efficiency.Today,with ever-expanding highway network,the improvement of vehicle speedand traffic density,on the work of automotive braking system relia becomeincreasingly important.Only vehicles which have good braking performance andreliable braking system can give full play to their high-speed dynamic performanceand to ensure the safety of traveling.This shows that the braking system is a veryimportant component of the vehicle,thus it's very important to the analysis and designof brake system bodies.bility requirementsKeywords:air brake Brake Transmission device
