Abstract
The automatic brake operating system is a cutting-edge active safety technology. It can be gradually developed because it relies on the calculation and analysis of the electronic control center to replace the people's own thinking operation of the traditional braking system, which makes the braking more convenient simple and more efficient. Moreover, the automatic brake operating system can effectively prevent the occurrence of traffic accidents and improve the safety performance of the vehicle. Combined with all the favorable factors, the system has gained more and more attention from people and has become the focus of research in various enterprises in recent years.
This design content analyzes the principle of the automatic brake operating system, determines the structural composition of the system according to the tasks to be completed by the system, and mainly performs the comparison and selection of the components used for the signal collection and processing unit. The components are simply introduced. In fact, the main content involved this time is to carry out a more detailed design of the execution unit. In the brake part, CATIA software is mainly used to perform detailed three-dimensional design of disc brake discs, brake calipers and brackets, in addition to the design calculations for pistons and friction pads. In the electronically controlled hydraulic drive part, the exterior design of components such as the hydraulic pump and the accumulator is mainly performed. In addition, the detailed working principle of the drive system is introduced, and the components involved in the power module are selected. Type analysis.
Finally, after completing the design analysis of all parts of the total system, this design was summed up and eager expectations for the future development of automatic brake operating system.
Key words:Automatic brake system;Information collection and processing;Electronically controlled and hydraulic drive;Disc brake.
