Abstract

The invention provides a combined cam shaft. The combined cam shaft comprises a core shaft with a shaft hole extending in the axial direction, a cam and transmission unit which sleeves the core shaftand is fixed to the core shaft in a tight expansion manner, and a plug pressed in a port of the shaft hole. The transmission unit is located at one end of the core shaft, and the plug and the transmission unit jointly serve as a power input connector part for the combined cam shaft. The plug is pressed in the end portion of the shaft hole of the core shaft, the plug plays a supporting role on thetransmission unit, the plug and the transmission unit can directly serve as the power input connector part for the cam shaft, a connecting transmission flange and other transition components are not needed, and a transmission mechanism of an engine is simplified

Description

technical field [0001] The invention relates to the field of automobile engines, in particular to a combined camshaft. Background technique [0002] The camshaft is one of the key transmission components of the automobile engine, which directly affects the performance of the engine. At present, the methods of manufacturing camshafts include: traditional integral casting method, forging method, and combined method of manufacturing camshafts. Among them, the use of casting and forging methods to manufacture camshafts has many disadvantages. For example, it is impossible to design and utilize the maximum performance of various parts of the camshaft, and the performance requirements of the cam, journal, mandrel, transmission unit, etc. It is very different. If a single material is used, the performance of each part cannot be maximized. The entire manufacturing process is complicated and requires a large number of mechanical processing procedures. The production efficiency is no...
