1. 研究目的与意义(文献综述)

the 21st century is an era of rapid development of automobile industry, which has gradually become a pillar industry in many countries. with the rapid development of china's national economy, the annual output and social ownership of automobiles are also growing rapidly. the quality of automobile is related to whether china's automobile industry can stride into the world. therefore, the improvement of automobiles and related products is also very important.

since the birth of automobiles, vehicle braking system plays a vital role in vehicle safety. in recent years, with the advancement of vehicle technology and the improvement of vehicle speed, this importance has become more and more obvious. in order to cope with the threat of high speed to people's safety, many regulations put forward higher requirements for vehicle safety, and the working reliability of automobile brake system becomes one of the most important aspects. the braking performance of automobiles is also regarded as the performance index of the seven major automobiles. its function is to ensure the safety performance of automobiles. automotive brake system is composed of many parts, and automobile hand brake arm is one of the essential parts. the function of brake system is to force the vehicle to slow down or stop, to keep the speed of downhill vehicle stable, and to keep the parked vehicle stationary in situ (including on the slope). as the core component of parking brake system, hand brake control arm ensures the braking stability of automobiles, and is also the last guarantee of people's life when driving. studying the structure of passenger driver brake arm assembly not only affects the high efficiency and long-life operation of automobile brake system, but also directly relates to the safety of automobile driving. continuous improvement and improvement of automobile hand brake arm is ultimately an indispensable task in the process of automobile design.

the development level of a country's automobile industry reflects the overall industrial level of the country. to develop a country's automobile industry, as far as the automobile industry is concerned, automobile design should be in a pivotal position. the design of brake arm is an important part of automobile design, especially with the development of modern automobile technology, the improvement of road conditions, the increasing speed and safety issues, which is an important component affecting automobile safety. hand brake arm is an important part of parking brake system. its efficiency and reliability are related to parking brake. in emergency situations, it also has the ability to limit high-speed driving of vehicles. its quality and safety are very obvious. therefore, in the process of rapid development of the automobile industry, we need to be more strict about its safety and reliability.
