Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, and particularly relates to a clamping type engine connecting rod. Background Art

[0002] The engine connecting rod is one of the key components of an automobile engine. Its function is to convert the reciprocating motion of the piston into the rotary motion of the crankshaft and transmit the gas pressure acting on the piston group to the crankshaft. Therefore, in addition to moving up and down, the engine connecting rod also needs to swing left and right to perform complex planar motions. When the engine connecting rod is working, it needs to bear the alternating load generated by the gas pressure and the reciprocating inertia force, and it is required to have sufficient fatigue strength and structural stiffness. At the same time, since the engine connecting rod is not only a transmission part but also a moving part, restricted by the unbalanced moment and moment of inertia of the crankshaft and piston, its load-bearing capacity cannot be improved by increasing its size.
