Abstract

The invention belongs to the field of engines, relates to a magnetoelectric drive rotary type variable valve assembly and aims to solve the problems in the prior art that drive and transmission mechanisms are complex, the valve motion parameters cannot be changed flexibly and continuously, and the like. The magnetoelectric drive rotary type variable valve assembly mainly comprises a cam, a cam shaft, a rotor body, a rotor bolt, a rotor gear, stator iron cores, a stator support, stator support bolts, a tappet, a valve spring, a valve, a valve guide pipe, a cylinder cover, bonding bolts, a rocker arm, a pin shaft, a rocker arm support, rocker arm support bolts and three line sets, wherein the stator iron cores are fixedly connected with the stator support and are installed inside the rockerarm, the rotor body is fixedly connected with the rotor gear, connected with the rocker arm through threads and arranged between the cam and the stator iron cores, the three line sets wind the opposite stator iron cores correspondingly, and after power is on, the stator iron cores attract the rotor gear to drive the rotor body to rotate up and down to change the distance between the cam and the rotor body, so that the opening time of the valve is changed. The magnetoelectric drive rotary type changeable air valve component saves space and is simple and convenient to assemble and high in work efficiency.

Description

technical field [0001] The invention belongs to the technical field of engines, and relates to a magneto-electrically driven rotary variable valve assembly. Background technique [0002] The engine valve mechanism is to open and close the intake and exhaust valves of each cylinder regularly according to the requirements of the working cycle and ignition sequence in each cylinder of the engine, so that the combustible mixture or air can enter the cylinder, and the burned exhaust gas can be discharged in time. , is an important mechanism to ensure the normal operation of the engine. [0003] However, since the opening and closing time and lift curve of the traditional valve train are fixed, they cannot provide reasonable valve timing with the change of actual working conditions, which reduces the charging efficiency and affects the economy and power. Variable valve technology has the following advantages: [0004] 1. Reduce pump gas loss and improve inflation efficiency; ...
