Promote the use of bicycles as a means of transport is one way to alleviate the contradictions; at the same time, the economic development makes the urban and rural residents have higher pursuit for quality of life, to enjoy life, good health and can choose slowly pleasurable cycling way.</p><p>In today's rapid economic development, people's awareness of environmental protection to improve daily, more to improve the living environment of mankind more and, in recent years, our country once again for the development and development of bicycle and put a lot of manpower and financial resources. This design is a small four wheel bike, the main characteristics of good balance and damping effect, we first use UG NX.10 drawing software to draw all of its parts and assembly drawings, and then make model identification mechanism.</p><p>The investment in small-scale four wheel mountain bike development needs to be accelerated. Although the small four wheeled mountain bikes have not yet been widely used, the development of energy and mileage has not yet made breakthrough progress, and has not been satisfactory. However, the small four wheel mountain bike has a bright future. From the point of view of technical development, after the long and difficult development course, the small four wheel mountain bike is facing a major technological breakthrough, and it is expected to become an important mode of recreation in twenty-first Century. </p><p> keywords ：Small scale；four wheel； mountain area； bicycle；mechanism；</p><p> 目 录</p><p>摘 要<span class="Apple-tab-span" style="white-space:pre"></span>I</p><p>1 绪论<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.1 研究的背景及意义<span class="Apple-tab-span" style="white-space:pre"></span>1</p><p>1.2 国内外四轮山地自行车研究动态及存在的问题<span class="Apple-tab-span" style="white-space:pre"></span>2</p><p>1.2.1国内山地自行车研究动态及存在问题<span class="Apple-tab-span" style="white-space:pre"></span>2</p><p>1.2.2国外四轮山地自行车研究动态及存在的问题<span class="Apple-tab-span" style="white-space:pre"></span>3</p><p>1.3 四轮山地自行车的选择方案<span class="Apple-tab-span" style="white-space:pre"></span>4</p><p>1.3.1方案一<span class="Apple-tab-span" style="white-space:pre"></span>4</p><p>1.3.2方案二<span class="Apple-tab-span" style="white-space:pre"></span>5</p><p>2 四轮山地自行车的概述及工作原理<span class="Apple-tab-span" style="white-space:pre"></span>6</p><p>2.1 自行车的概述<span class="Apple-tab-span" style="white-space:pre"></span>6</p><p>2.2 四轮自行车的机构分析，组成部分及工作原理<span class="Apple-tab-span" style="white-space:pre"></span>6</p><p>2.2.1对四轮自行车的机构分析及特点<span class="Apple-tab-span" style="white-space:pre"></span>6</p><p>2.2.2四轮山地自行车的平衡原理<span class="Apple-tab-span" style="white-space:pre"></span>7</p><p>2.2.3四轮自行车的组成部分及工作原理<span class="Apple-tab-span" style="white-space:pre"></span>7</p><p>3 四轮山地自行车链传动的机构设计<span class="Apple-tab-span" style="white-space:pre"></span>9</p><p>3.1 链传动特点及应用<span class="Apple-tab-span" style="white-space:pre"></span>9</p><p>3.2 链传动参数的选择<span class="Apple-tab-span" style="white-space:pre"></span>9</p><p>3.3 滚子链轮的结构和材料<span class="Apple-tab-span" style="white-space:pre"></span>10</p><p>3.4 链轮的失效形式<span class="Apple-tab-span" style="white-space:pre"></span>11</p><p>3.5 滚子链传动的设计计算<span class="Apple-tab-span" style="white-space:pre"></span>11</p><p>4 机构的认定<span class="Apple-tab-span" style="white-space:pre"></span>13</p><p>4.1 材料的购买并准备过程<span class="Apple-tab-span" style="white-space:pre"></span>13</p><p>4.2 模型的完成过程<span class="Apple-tab-span" style="white-space:pre"></span>14</p><p>4.3 制作过程中遇到的问题<span class="Apple-tab-span" style="white-space:pre"></span>15</p><p>5 自行车的组装要求及操作方式<span class="Apple-tab-span" style="white-space:pre"></span>17</p><p>5.1自行车的安装注意事项<span class="Apple-tab-span" style="white-space:pre"></span>17</p><p>5.2自行车的试验要求<span class="Apple-tab-span" style="white-space:pre"></span>17</p><p>6 自行车维护<span class="Apple-tab-span" style="white-space:pre"></span>18</p><p>6.1传动系统的维护<span class="Apple-tab-span" style="white-space:pre"></span>18</p><p>7 总结与展望<span class="Apple-tab-span" style="white-space:pre"></span>20</p><p>参考文献<span class="Apple-tab-span" style="white-space:pre"></span>21</p><p>致谢<span class="Apple-tab-span" style="white-space: pre;"></span>22</p><p><br/></p>
