Embodiment Construction

[0009] like figure 1 , a camshaft of an automobile engine, the camshaft 10 is arranged in the axial direction

[0010] There is a main oil passage 11, and the main oil passage 11 located at the first journal of the camshaft 10 is provided with a partition 20 that divides the main oil passage 11 into an open cavity 11a and a closed cavity 11b, and the camshaft 10 with the open cavity 11a An oil passage 12 communicating with the phaser is provided on the top, an oil inlet 13 communicating with the main oil passage 11 is provided at the first journal of the closed cavity 11b, and an oil inlet 13 communicating with the main oil passage 11 is provided at the journal of the camshaft 10 that cooperates with the remaining bearing caps. There is an auxiliary oil passage 14 communicating with the main oil passage 11. The oil inlet hole 13 corresponds to the oil passage on the first bearing cap. After lubricating oil is introduced into the first bearing cap from the cylinder head, it fl...

Abstract

The invention relates to the field of automobile engines, in particular to an automobile engine camshaft which is characterized by comprising a main oil gallery in an axial direction and a partition member used for partitioning the main oil gallery into an open cavity and a closed cavity and arranged in the main oil gallery positioned at a first shaft neck of the camshaft, wherein an oil path communicated with a phaser is arranged on the camshaft at the open cavity end, an oil inlet hole communicated with the main oil gallery is arranged at the first shaft neck at the closed cavity end, and the cam shaft and other shaft necks matched with bearing covers are all provided with auxiliary oil galleries communicated with the main oil gallery. Because the camshaft is provided with lubricating oil galleries in per se and lubricating oil of the camshaft is supplied by the first bearing cover, the automobile engine camshaft reduces the quantity of the oil galleries arranged on a cylinder cover, lowers the machining difficulty and has the advantages of cost saving, improvement of the working efficiency, compact structure and reduction of the volume space of engines and weight reduction.

Description

technical field [0001] The invention relates to the field of automobile engines, in particular to an automobile engine camshaft. Background technique [0002] All the journals of the camshaft of a traditional automobile engine that cooperate with the bearing housing are lubricated through the oil passages on the cast cylinder head. Difficult, the difficulty of machining is high, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to provide an engine camshaft with simple opening of lubricating oil passage and convenient processing. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a camshaft of an automobile engine, the camshaft is provided with a main oil passage along the axial direction, and the main oil passage at the first journal of the camshaft is provided with a The main oil passage is divided into an open chamber and a closed chamber partition. The camshaft ...
