Abstract

本发明公开一种传动系统，应用于卡丁车车体的非独立悬架或独立悬架上；所述传动系统包括传动箱体和所述传动箱体内的传动轮组合而成；所述传动箱体为齿轮传动箱体、链轮链条传动箱体、过桥齿轮传动箱体或过桥链轮链条传动箱体；所述传动轮为传动齿轮或链轮链条。本发明的有益效果：本发明可将发动机输出的动力高效的传递至驱动桥上，使车辆能更好的适应越野路面的行驶，车辆获得更稳定的驱动力；同时，将发动机与驱动桥分离安装，发动机安装在车架上，减小了驱动桥的簧下质量提高了驾乘人员的舒适性。

Description

一种传动系统 技术领域
本发明涉及卡丁车技术领域，具体为一种传动系统。
背景技术
现有的全地形卡丁车是将发动机与后悬架安装成整体结构形式的后驱动桥，但这种驱动桥的方式并不能很好的适应越野路面时的工况，同时也不能兼顾驾乘人员的舒适性，造成此种原因是由于上述车辆的体积短小，于是发动机的安装位置受到了很大的局限，大部分车型将发动机与后悬架设计安装成整体结构形式的驱动桥，后悬架摆臂是刚性结构，摆臂下安装驱动硬轴，摆臂上安装发动机，将发动机、后悬架摆臂以及驱动硬轴安装固定成刚性的单摆臂结构的驱动后桥，这样才能有效的使用链条来传递发动机至驱动轴的动力，才能有效的使用减震弹簧来减小震动。
但这样的驱动桥缺点随之而来，由于后悬架摆臂成整体刚性结构，簧下质量大幅增加，悬架在起伏路面的响应性能大幅下降，不能及时有效的减缓来自路面的冲击力，由于悬架摆臂成整体刚性结构，在悬架起伏跳动时只能在与车架相连接的两点处作绕轴运动，刚性驱动桥不能与前轴形成交叉轴的工况，因此车辆行驶在越野路面时每个车轮的巡迹性较差，总会有一个车轮处于腾空状态，不能实时紧贴路面行驶，降低了动力传递的效率。
因此，设计出一种性能优良、传动效率高而又能适应越野路面行驶、又能兼顾驾乘舒适性的卡丁车新型传动系统势在必行。
