Abstract

The invention provides a camshaft phase modulator oil channel separation device in the technical field of valve timing. A phase modulator (2) is connected to a camshaft (1). A middle hole (5) is formed in the middle portion of the separation device (4) arranged in a cavity (3) at the end of the camshaft (1). One end of the separation device (4) is movably connected to the bottom of the cavity (3) of the camshaft (1), and the other end of the separation device (4) is fixedly connected to the phase modulator (2). Both ends of a channel (6) between the separation device (4) and the cavity (3) are respectively communicated with a second oil channel (7) and a phase modulator oil channel A (10). Both ends of the middle hole (5) of the separation device (4) are respectively communicated with a first oil channel (9) and a phase modulator oil channel B (8). The camshaft phase modulator oil channel separation device can regulate and control the operating state of the phase modulator as well as ensure the automobile engine performance. The camshaft phase modulator oil channel separation device can reduce the complexity of an engine camshaft machining technology.

Description

technical field [0001] The invention belongs to the technical field of automobile engine valve timing, and more specifically relates to a phaser oil passage separation device for an automobile engine camshaft. Background technique [0002] Vehicle engine variable valve timing technology (VVT, Variable Valve Timing) is a new technology that has been widely used in modern cars in recent years. Automobile engines adopt variable valve timing technology, which can increase the intake charge of the engine and increase the charge coefficient to achieve the purpose of energy saving and emission reduction. The realization of variable valve timing technology is generally driven by a hydraulic phaser, and the phaser is installed on the camshaft. In order to realize the drive of the hydraulic phaser, a complex oil supply circuit needs to be designed on the camshaft. For this reason, the first shaft of the camshaft needs to be as long as possible, which is contrary to the current requi...
