Problems solved by technology
[0002] At present, the engine of a car basically uses a crank-connecting rod mechanism to convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The impact of the horizontal force component of the connecting rod tilt can easily lead to left and right cylinder knocking. When the piston connecting rod is twisted or the crankshaft main journal is not parallel to the center line of the connecting rod journal, the small head of the connecting rod swings back and forth, which will also cause cylinder knocking

The invention relates to a novel automobile engine transmission mechanism. The novel automobile engine transmission mechanism comprises air cylinders, pistons, connecting shafts and gears. The upper portions of the pistons are in sliding fit with the corresponding air cylinders. Each piston is of a cup-shaped structure with an opening in the lower end. The connecting shafts are inserted into inner holes of the corresponding pistons from bottom to top. The outer cylindrical surface of each connecting shaft is provided with hemispheric protrusions or grooves. The inner cylindrical surface of the inner hole of each piston is provided with grooves or hemispheric protrusions. The pistons are movably connected with the corresponding connecting shafts through cooperation of the hemispheric protrusions and the grooves. Each groove is composed of a pair of left-handed spiral groove section and right-handed spiral groove section, and other parameters of the left-handed spiral groove section and the right-handed spiral groove section are all the same except spiral directions. The grooves are unbroken and closed. The locations where the grooves extend occupy a whole circumference of an entity. The lower ends of the connecting shafts are coaxially and fixedly connected with the corresponding gears. The novel automobile engine transmission mechanism is simple in structure, stable in operation, high in power and free of piston knocking.
Description
technical field [0001] The invention relates to a transmission mechanism of an automobile engine. Background technique [0002] At present, the engine of a car basically uses a crank-connecting rod mechanism to convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The impact of the horizontal force component of the connecting rod tilt can easily lead to left and right cylinder knocking. When the piston connecting rod is twisted or the crankshaft main journal is not parallel to the centerline of the connecting rod journal, the small head of the connecting rod swings back and forth, which will also cause cylinder knocking. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel automobile engine transmission mechanism, which does not produce cylinder knocking. [0004] Main technical scheme of the present invention has: [0005] A new type of automobi...
