Embodiment Construction

[0014] An exemplary embodiment will be described below with reference to the drawings.

[0015] figure 1 It is a schematic diagram showing the position and connection relationship between the parts of the mechanism. One end of the variable speed pendulum 7 has a roller 12 and a shaft 11, the roller 12 is in close contact with the cam 1 and is pushed by the cam 1; the other end is connected with the boss of the variable speed pendulum 2 through the shaft 10. One end of the variable speed pendulum 6 is fixed on the cylinder head through the rotating shaft 5, and can rotate according to the rotating shaft 5. Roller 24 is arranged on fulcrum rod 8, and roller 24 contacts with the side of variable speed pendulum 7, becomes the support point of swing of variable speed pendulum 7; Turn and pull up and down. One side of the fulcrum rod 8 is pressed by the eccentric shaft 21 , so that the fulcrum rod 8 can support the lateral pressure of the shift pendulum 7 . The end face of the v...

Abstract

The invention relates to an independently adjustable continuous variable valve timing and lift mechanism, which comprises a camshaft, a variable-speed swing system, a fulcrum rod, a crank rocker arm, an eccentric shaft, a roller rocker arm and a torsional spring. A cam pushes the variable-speed swing system, and a roller on the fulcrum rod is used as a fulcrum for the variable-speed swing system to swing with adjustable swinging speed and adjustable amplitude. The perpendicular position of the fulcrum rod is controlled via the crank rocker arm, the cam is controlled by an involute so that the horizontal position of the fulcrum rod is controlled, the position of the fulcrum of the variable-speed swing system is changed, then the swinging of the variable-speed swing system is changed, and the purpose of independently adjusting valve timing and lift within a certain range is achieved.

Description

technical field [0001] The invention relates to an independently adjustable continuously variable valve timing and lift mechanism, the lift and timing of the internal combustion engine valve driven by it can be independently adjusted within a certain range. Background technique [0002] The valve drive of the internal combustion engine adopts continuously variable valve timing, which can increase the filling rate of the cylinder of the internal combustion engine, improve power and efficiency, reduce the working temperature of the cylinder, and reduce the pollution emission of the internal combustion engine. The intake valve drive of the internal combustion engine adopts the continuously variable valve lift technology, which can improve the intake efficiency of the internal combustion engine, reduce fuel consumption, and improve the response speed of the internal combustion engine to the throttle. [0003] In the patent of publication number CN101149000A titled variable valve...
