Novel internal combustion engine transmission device

Abstract

According to the novel internal combustion engine transmission device, the length of a piston is increased, the tail end of the piston is limited through a sliding sleeve, a rack capable of moving up and down under the timely effect of an eccentric cam is additionally arranged in the middle of the piston, an independent power output shaft is arranged on one side of the piston, and a pulsation device is formed by combining a plurality of perfect circle gears and oval gears. When the crank connecting rod mechanism works, the crank connecting rod mechanism is timely engaged with or disengaged from the rack on the piston, so that the power obtained by the piston in a power stroke forms torque on the independent power output shaft through the pulsation device, the original crank connecting rod mechanism does not have a power output function and only assists the piston in performing various stroke actions, and the defect of low transmission efficiency of the crank connecting rod mechanism is avoided; therefore, the heat engine efficiency of the internal combustion engine is greatly improved.

Description

Technical field:

[0001] The invention belongs to mechanical manufacturing, and specifically relates to a brand-new technical solution for energy transmission of an internal combustion engine. Background technology:

[0002] As is known to all, the existing internal combustion engine transmission device, except for the rotary engine, mainly uses the crank-connecting rod mechanism to convert the linear reciprocating motion of the piston into rotary motion. This energy transmission is stable and reliable, but the fatal disadvantage is that when the piston is at the upper and lower dead points, the crank-connecting rod mechanism is basically in a transmission failure state, and the energy is consumed internally, which invisibly increases the fuel ratio, generates a large amount of exhaust gas, and increases exhaust pollution, which is a huge challenge to the earth's energy. The technical solution described in the present invention is to overcome the existing drawbacks, effectively increase the transmission efficiency, reduce the fuel ratio of the internal combustion engine, reduce exhaust gas emissions, save a lot of petrochemical energy, and effectively reduce environmental protection pressures such as energy saving and emission reduction. Summary of the invention:

[0003] The present invention is implemented in the following way: the length of the piston cylinder is lengthened, the piston is limited by a sliding sleeve or the like at the end of the lengthened piston (non-air chamber end), and is connected to a crank-connecting rod device; a rack that can move up and down as designed is provided in the middle part of the lengthened piston; a power output shaft is provided on the side of the lengthened piston; the output shaft is in the form of a gear, and is regularly engaged and disengaged with the rack through a pulsating device composed of a plurality of gears and elliptical gears, so that the power generated by the piston during the piston power stroke is engaged by the rack and the pulsating device, thereby generating torque on the power output shaft; and the rack is disengaged from the pulsating device as required by the design during other piston strokes, so that the piston continues to move under the action of the crank-connecting rod mechanism without being affected by the power output shaft, so that the crank-connecting rod mechanism is disengaged from the power output function, thereby avoiding the transmission disadvantages of the crank-connecting rod mechanism and realizing a new form of internal combustion engine transmission.

[0017] The embodiment of the present invention is Figure 1 Take the single-cylinder four-stroke internal combustion engine shown in the figure as an example. Figure 1 As shown, when the power stroke occurs, the rack 7 that can move up and down is pushed up and engaged with the elliptical gear 2 with a spur gear under the timely cooperation of the eccentric cam 9, and the extended piston 6 moves under the impetus of the gas in the steel sleeve 5, and acts on the power output shaft 1 through the rack and the pulsation device to form a torque; when other strokes are performed; the rack 7 that can move up and down is disengaged from the elliptical gear 2 with a spur gear under the joint action of the eccentric cam 9 and the spring 8, and freely completes each stroke action under the action of the crank-connecting rod mechanism 4. The gear 2 and the gear 3 can be designed to be multiple, and their function is to generate pulsation, and the uniform motion of the power output shaft 1 is highly matched with the irregular motion speed of the extended piston 6, which is conducive to the engagement or disengagement of the rack 7 that can move up and down with the elliptical gear 2 with a spur gear. Such a mechanism is made into a multi-cylinder internal combustion engine, which can greatly improve the stability of the mechanical structure and the efficiency of the thermal engine.
