摘　　要：根据全国大学生工程训练综合能力竞赛"重力势能驱动的具有方向控制功能的自行小车"的创新思维活动要求,进行了小车结构的创新性设计,提出了双前轮转向机构,很好地解决了小车在沿s形轨迹行进过程中的差速问题,无碳小车采用曲柄滑块机构进行s形轨迹的转向控制,行走机构采用一级齿轮传动,多组齿轮快换进行桩距调节。设计中采用MATLAB进行计算及可行性模拟分析,采用Pro E进行三维建模设计,并进行了加工组装与调试参赛,并根据比赛实际问题进行了改进。小车结构设计新颖,在转向、传动机构等方面的设计创新性获得专家评委的一致好评。According to the proposition of the National College Engineering Training Comprehensive Ability Competition,focus on a carbon-free car（driven by gravitational potential energy has direction control function of the self-propelled trolley）innovative design activities,an innovative design with double front steering wheel mechanism is carried out. The structure design well solves the differential speed problem when car traveling along S-shaped. The car using slider crank mechanism to realize S shape track steering control,walking mechanism adopts primary gear driving. The gears can be quickly changed to realize the varying pile space. MATLAB was used in the design and the feasibility of the simulation analysis,the Pro E was used for 3 D modeling and design. After processing design,machining,assembling and debugging,the car has been completed and taken the Beijing competition. The structure of the car has been improved after race. The innovation of the design of the steering and transmission mechanism is novel,and has been praised.
