【正文】 adhesion coefficient, strength, and brake, and maximum braking torque parameters calculation, etc. The second brake and its ponents: the brake disc and calliper, friction lining block size of ponents etc brake calculation and material selection, The third in the design in the rear brake selection in the rear brake disc, install the parking brake on the mechanical structure, Fourth: brake wheel drive mechanism brake cylinder, the brake pedal stroke the cylinder, and the design calculation. After the design of brake ,this paper start the checking of braking deceleration and braking distance, analyzed the stability of braking efficiency and braking direction, and drawn out with MATLAB braking force distribution curve, above all ply with the design requirements, and verifies the rationality of the design of the brakes. Finally, according to the design and calculation using CAD drawing brake assembly and brake caliper disc brake, piston, liner, friction parts ,at the same time ,the paper also carried a threedimensional modeling. In addition, this paper briefly introduces the drive mechanism brake type selection, brake main cylinder pipe, braking system, the selection of multiloop research status of brake and development prospects. Key words: brake disc CAD MATLAB design modeling VII 目 錄 摘要 ...................................................................
