Research On Key Technology Of Auto Float Caliper Disc Brake

Float brake caliper disc brake is executed in the system components, and other role, compared to the brake type brake with brake high efficiency, brake superior performance, etc. At the same time, the brakes in use process, there also exist some disadvantages such as fever vibration. This thesis aims to use that appear in the process of strength, fever, vibration problems such as thorough research, to improve the comprehensive performance provides the basis.Strength design is an important part of the brake design, this paper analyses the brakes of key parts brake caliper and braking force situation and use stent establishing its physical model and UG of finite element software, the static stress analysis and correction, find out the maximum stress position, through improvements in intensity vulnerabilities, make its maximum stress got reduced significantly, and prove that the improved structure is accord with strength design principles.Braking process brake disc and friction slices frictional contact, will kinetic energy converted to heat energy, lead to brake disks temperature rises, reduce its braking efficiency. Paper established the friction heat generating the mathematical model and fem analysis model, and temperature characteristic.The simulation. Got braking process temperature distribution of games, compares under different pressure, temperature distributions under different thickness, find out the biggest impact factors on temperature. Analysis of the brake piece in only pressure, only pressure and friction, have pressure friction and temperature three cases, find out the contact pressure interface pressure distribution rule.Analyses the reason caused brake vibrations, established the brake disc finite element model, and the finite element modal analysis, vibration control for brake provides theoretical basis.
