Abstract

本实用新型公开了一种凸轮轴，包括凸轮和轴体，凸轮与轴体紧配连接，所述轴体为中空式结构，且内孔为通孔。作为优选，所述轴体采用铸钢材质一次成型结构。作为优选，所述轴体横截面外部为椭圆形内孔为圆形结构。本实用新型的有益效果：本实用新型即节省了材料，而且零件要求精度不高，易加工，轴体选用中空结构不需要另设油管，可将轴体孔作为油管使用，本新型结构简单非常实用。

Description

一种凸轮轴
技术领域
本实用新型属于汽车领域，特别涉及汽车发动机上的凸轮轴。 
背景技术
现有的凸轮轴轴体一般都是实心的，其材料使用量大，生产成本高，而且难加工，且工序繁琐。 
实用新型内容
针对现有技术的不足，本实用新型提供一种凸轮轴。 
为了实现上述目的，本实用新型所采取的技术方案是： 
一种凸轮轴，包括凸轮和轴体，凸轮与轴体紧配连接，所述轴体为中空式结构，且内孔为通孔。 
作为优选，所述轴体采用铸钢材质一次成型结构。 
作为优选，所述轴体横截面外部为椭圆形，内孔为圆形结构。 
本实用新型的有益效果：本实用新型即节省了材料，而且零件要求精度不高，易加工，轴体选用中空结构不需要另设油管，可将轴体孔作为油管使用，本新型结构简单非常实用。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
如图1所示的一种凸轮轴，包括凸轮1和轴体2，凸轮1与轴体2紧配连接，所述轴体2为中空式结构，且内孔3为通孔。所述轴体 2采用铸钢材质一次成型结构。所述轴体横截面外部为椭圆形内孔3为圆形结构。 
本实用新型即节省了材料，而且零件要求精度不高，易加工，轴体2选用中空结构不需要另设油管，可将轴体内孔3作为油管使用，本新型结构简单非常实用。 
以上为本实用新型最佳实施方式，本领域内普通的技术人员的简单更改和替换都是本实用新型的保护范围之内。 

Claims (3)
