Embodiment Construction

[0016] like figure 1 and figure 2 As shown, a new type of crank-slider mechanism that can change the engine displacement includes a cylinder 8, a piston 9 located in the cylinder 8, a connecting rod 6 connected with the piston 9, connected with the end of the connecting rod 6 and connected by the connecting rod. Rod 6 drives rotating turntable 3, an adjusting mechanism arranged on turntable 3 to adjust the radial position of the end of connecting rod 6 on turntable 3, and an output shaft 7 arranged on the adjusting mechanism. The adjustment mechanism includes a first bracket 20 radially arranged on the turntable 3, a second bracket 5 connected to the output shaft 7, the two ends are respectively slid on the first bracket 20 and the second bracket 5, and the middle is connected to the second bracket 5. The end of the rod 6 is transferred to the slider 4 . The first lead screw 21 in the radial direction of the turntable 3 is provided in the first support 20, the second lead s...

Abstract

The invention provides a novel slider-crank mechanism capable of changing the engine displacement. The novel slider-crank mechanism comprises an air cylinder, a piston, a connection rod, a rotary disc, a regulating mechanism and an output shaft, wherein the piston is arranged in the air cylinder, the connection rod is connected with the piston, the rotary disc is connected to one end portion of the connection rod and driven by the connection rod to rotate, the regulating mechanism is arranged on the rotary disc to regulate the radial position of the end portion of the connection rod on the rotary disc, and the output shaft is arranged on the regulating mechanism. By regulating the radial position of the end portion of the connection rod connected with the piston in the rotary disc, the piston stroke of the air cylinder of an engine is regulated, and accordingly, the engine displacement is regulated, and the engine applicability is improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to a novel crank-slider mechanism capable of changing the displacement of the engine. Background technique [0002] The engine is a power generating device widely used in machinery, and the performance index of the engine is closely related to the displacement. The displacement of the engine is the sum of the working volume of each cylinder of the engine, and the working volume of the cylinder refers to the gas volume swept by the piston from the top dead center to the bottom dead center, which depends on the bore and piston stroke. The cylinder bore and piston stroke of the current engine are fixed, which makes the displacement of the engine fixed and cannot be adjusted, resulting in poor applicability of the engine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel crank-slider mechanism capable of changing the engine dis...
