Design Research of the Electric Gun Mounting Bracket Used for Parking Pre-tightening Force Adjusting Nut

Abstract

For the problem how to fix constant torque electric gun, in parking brake equipped with automatic adjustment system, we propose two solutions, and select a more suitable solution by theoretical analysis. Based on the structure of the handbrake and the electric gun, using 3D modeling software to design the selected solution. At same time, use the finite element analysis to analyze the stress and strain of the leaf spring status. Finally, the solution will be converted to real, and verified that liquid rubber can effectively reduce the spring leaf rivals on the handbrake spring leaf structure by test method, and ultimately proved the feasibility of the design.
