The invention relates to a translation and rotation mutual coupling device, and belongs to the technical field of mechanical design. The translation and rotation mutual coupling device comprises an intake valve, control cavities, a rotating shaft, a rotating rod, a stretching rod, springs, a moving body, moving plates and a connecting pipe. Four cavities are formed in the rotating shaft. Four ribs are arranged in the middle section of the intake valve. The four ribs in the middle section of the intake valve are arranged in the four cavities of the rotating shaft respectively. The slope structure of the moving body, the slope structure of the first moving plate and the slope structure of the second moving plate are matched with one another, the first moving plate and the second moving plate are connected with the right wall face and the left wall face of the second control cavity through the first spring and the second spring respectively, one end of the connecting pipe is communicated with the lower cavity of the second control cavity, and the other end of the connecting pipe is communicated with a turbine exhaust pipe. According to the translation and rotation mutual coupling device, when the pressure in the control cavities is high, the middle section of the intake valve rotates anticlockwise, the lift of the intake valve is increased, and the air inlet amount of an engine is increased. The translation and rotation mutual coupling device is reasonable in design, simple in structure and suitable for designing of an intake valve lift continuous variable system.
Description
Technical field [0001] The invention belongs to the technical field of internal combustion engines. Specifically, it is a translational rotation mutual coupling device capable of realizing continuous variable lift of an intake valve in a pneumatic principle. Background technique [0002] The valve lift of a traditional gasoline engine is fixed and immutable, that is, there is only one cam profile of the camshaft, which makes it impossible for the lift to make the engine respond well in both high-speed and low-speed regions. The valve lift of the traditional gasoline engine, namely the cam profile design, is a balanced choice for the engine under all working conditions. As a result, the engine can neither obtain the best high-speed efficiency nor the best low-speed torque. In order to achieve the most balanced performance under all working conditions. The use of variable valve lift enables the engine to obtain the required valve lift in both high-speed and low-speed regions, ther...
