Smart camshaft phase regulator of variable valve timing system of engine

Abstract

The invention relates to a smart camshaft phase regulator of a variable valve timing system of an engine, in particular to a smart camshaft phase regulator capable of greatly shortening the axial size, which aims to solve the problems that the front end of the engine is difficult to arrange due to the overlarge axial size of a traditional product. The invention has compact and simple structure, small axial size, high response speed and great output torque. The invention adopts the technical scheme that the smart camshaft phase regulator of the variable valve timing system of the engine comprises a plug, a sealing gasket, a front end cover, a rear end cover, a hollow shell, a rotor and a return spring and is characterized in that the plug and the sealing gasket are connected with the front end cover together, the front end cover and the rear end cover are respectively connected with the shell which is hollow inside, the rotor is arranged in the shell, the front end cover is dented inwards to form a radial groove, one side of the rotor, which is close to the front end cover, is dented inwards to form a groove, and the return spring is arranged in a hollow cavity formed by the radial groove and the groove. The invention is mainly applied to the camshaft phase regulator of the engine.

Description

technical field [0001] The invention relates to a camshaft phase adjuster in an engine timing system, in particular to an intelligent camshaft phase adjuster capable of greatly shortening the axial dimension. technical background [0002] The variable valve timing system is widely used in new automobile engines, which can increase engine power and torque, and reduce fuel consumption and exhaust emissions. The connection between the camshaft, the timing gear and the crankshaft of the traditional engine is fixed, that is, the gas distribution phase is fixed. The variable valve timing system can make the valve opening time relative to the crankshaft angle adjustable within a certain range, so that the distribution The gas phase is optimized to achieve the purpose of increasing engine power and torque, reducing fuel consumption and exhaust emissions. The camshaft phaser is a key component of the variable valve timing system. Its function is to form a variable valve timing betwee...
