Description

technical field [0001] The invention relates to the technical field of automobile fluid parts, in particular to an automobile automatic adjustment arm. Background technique [0002] Automatic brake clearance adjustment arm, also known as "automatic clearance adjustment arm" or "automatic adjustment arm". Automatic arm adjustment is a mature technology abroad and has been widely used. In recent years, manufacturers of trucks, buses, and trailers in Europe, America and other regions have adopted it as a standard configuration for complete vehicles. The function of the automatic adjusting arm should be to accurately register the amount of clearance increase due to friction lining wear and accurately adjust the brake clearance to the normal working range. [0003] The angular travel of the adjusting arm during braking can be divided into three parts: 1. Clearance angle, which corresponds to the normal clearance between the brake drum and the friction lining; 2. Excessive cl...
