摘  要
通过对第二届全国大学生工程训练参赛作品“无碳重力势能小车”的分析。发现小车在设计方面存在不足。

为了改进小车的不足之处，对小车的结构部分进行重新设计。通过每一阶段的深入分析把设计尽可能向最优

设计靠拢。
根据小车功能要求，把小车分为车架 、原动机构 、传动机构 、转向机构 、行走机构 、微调机构六个模块

，进行模块化设计。首先针对每一个模块进行多方案设计，通过综合对比选择出最优的方案组合。确定的方

案为：车架采用三角底板式、原动机构采用了锥形轴、传动机构采用齿轮、转向机构采用曲柄摇杆、行走机

构采用单轮驱动实现差速、微调机构采用微调螺母。然后对方案进行理论分析，综合考虑零件材料性能、加

工工艺等，进而得出了小车的具体参数，和运动规律。

Abstract
  Based on the second national college engineering training entries" carbon-free gravitational

potential energy car" analysis. Find cart in the design deficiencies. In order to improve the

deficiency of the trolley car, a portion of the structure redesign. Through each phase of the

in-depth analysis of the design as possible to move closer to optimal design.
  According to the functional requirements of the trolley car, divided into frame, driving

mechanism, a transmission mechanism, a steering mechanism, a walking mechanism, a fine

adjustment mechanism of six modules, modular design. First, for each module performs multiple

design, through comprehensive comparison and choose the optimal scheme of combination.

Determining the scheme are: frame with triangular bottom plate type, motive mechanism adopts a

conical shaft, the drive mechanism adopts gear, steering mechanism with crank rocker, walking

mechanism driven by a single wheel to achieve differential, fine tuning mechanism by fine

adjustment nut. Then the scheme theory analysis, considering the parts and materials

properties, processing technology, and then the specific parameters, and movement rules.
