Here mainly includes: transmission system design, platform design, steering system design. The graduation design on the design of the basic skills training, enhancing the analysis and to solve engineering problems, and create a certain condition for general mechanical design. The structure is mainly produced by the motor power through the coupling will need to transmit power to the drive shaft, the drive shaft drives a universal coupling, drive the wheels, so as to drive the device, improve labor productivity and automation level of production. But also show its superiority, there are broad prospects for the development. The research of this thesis: (1) the design of overall structure design of automatic obstacle avoidance damping trolley. (2) analysis and design work performance of automatic obstacle avoidance of car shock absorber. (3) the choice of motor. (4) transmission system, design of the executive component and bench design of automatic obstacle avoidance damping trolley. (5) the design of components for the design calculation and check. (6) the use of computer aided design, 3D modeling on Design of parts. (7) to draw the assembly drawing and parts assembly diagram and parts diagram design.
