无碳小车的设计与实现
摘要
本文围绕无碳小车的设计,以全国大学生工程训练综合能力竞赛的竞赛命题为核心,系统地说明了符合比赛要求的无碳小车从设计构思到参数计算以及最后的加工装配的设计思路和步骤。主要介绍了无碳小车的机械机构构成、技术参数、零件机械加工工艺、小车零部件的加工方式与加工装配。
无碳小车主要由车体、驱动机构、传动机构、转向机构和微调机构六个机械结构组成,其中转向机构为无碳小车实现行驶S型轨迹的机构,是无碳小车核心机构。该小车的转向机构根据正弦机构的原理,在正弦机构的基础上优化和修改而来。而微调机构则是用于调整转向机构的周期,使小车的行驶轨迹能够根据实际需要而改变。转向机构和微调机构的设计是无碳小车设计最为重要的一部分,是实现竞赛命题的要求的核心机构。
在小车加工调试完成后,经过验证小车的设计与制造符合竞赛命题的性能要求。通过这次设计,增强了我们的综合能力,并真正能把所学知识真正用在工作和生活中。

Design and Implementation of carbon-free Vehicle
Abstract
This paper focuses on design of carbon-free vehicle, contest of the petition for engineering training college prehensive ability as the core system that meets the game requirements, parameter calculation and carbon-free vehicle from design concept to final design idea and steps of processing and assembling. Introduces carbon-free vehicle for mechanical structure, technical parameters and machining of parts, car parts and processing method and processing and Assembly.
Carbon-free vehicle is mainly driven by the body, body, transmission, steering gear, trimmer bodies consists of six mechanical structure, including steering mechanism for carbon-free car bodies to achieve s-bend, that is carbon-neutral core trolley Agency. The car's steering mechanism based on the principle of sine mechanism, in sine mechanism based on optimization and modification. And fine-tuning is used to adjust the steering mechanism of the period, the car of course can change according to the actual need. Steering mechanisms and fine-tuning mechanism is designed to be carbon-free car design is the most important part of is the core institutions meet the contest requirements.
Processing in the car after debugging plete, proven performance of car design and manufacture meet the contest requirements. Through this design enhances our overall ability and really can really use what they have
