Abstract

In the connecting rod, one of the two coaxial eccentric parts 5, 6 is configured to be positioned inside the other one, and guides an arm directly connected to the eccentric part and the spring 11, and one end thereof has a spring compression mechanism 8 In the system in which the other end is connected to the motor body, the spring 11 is fully relaxed when the piston 2 is at the top dead center. As the crankshaft 20 rotates, the piston 2 presses the connecting rod 4 from the top dead center by the combustion gas. In addition, the relaxed spring 11 supported by the caulking catch lever support presses the large eccentric 5 downwardly by the caulking catch lever. These two actions affect the small eccentric portion 6 inside the large eccentric portion 5, and the crank peg 7 inside the small eccentric portion 6 is moved downward by an additional moment arm. By being pressurized, the rotation moment applied to the crankshaft 20 is increased.

Description

ECCENTRIC AND SPRING SYSTEM FOR THE INTERNAL AND EXTERNAL COMBUSTION PISTON MOTORS}

In conventional engines, the moment arm length was equal to the maximum radius of the crankshaft rotation circumference or half of the piston stroke.

U.S. Patent No. 95/00742 provides long moment arms by eccentric means separate from the crankshaft rotational circumference and the piston stroke, whereby the crank peg is fixed while the piston stroke is variable and suction And the explosion stroke are different from each other. That is, the suction stroke is long. A spring is provided between the eccentrics in the connecting rod. The compression ratio can be changed by various variables; Such variables include a change in the spring support point for compressing and fixing the arm, and a phenomenon in which the piston approaches or moves away from the bottom dead center due to the spring being located between the coaxial eccentric members of the connecting rod 4. This provides more powerful and higher torque at high speeds. However, the two eccentric members formed on the connecting rod are impacted by the spring, which causes various problems during the production stage.

The present invention relates to the production of an environmentally friendly and powerful high speed motor which is independent of a piston stroke and a crankshaft rotation circumference in an internal combustion engine and an external combustion engine, and has a spring mechanism for extending a crank moment arm.

An object of the present invention is to extend a moment arm in an internal combustion engine and an external combustion engine with a piston by varying the connection center of the connecting rod in the direction of action, the two eccentrics and the crankshaft center in the connecting rod 4. Is fixed; By fixing the crankshaft arm axis line to which the connecting rod 4 is connected and the axis of the connecting rod 4, it is possible to produce an environmentally friendly and powerful high speed motor.

The spring mechanism, which enhances the power, torque and speed of the motor by extending the crank moment arm in the internal combustion engine and the external combustion engine, has two coaxial eccentric portions 5 and 6 located on the crank peg 7 of the connecting rod 4. A guide arm (6) directly connected to the small eccentric member and moving with the eccentric member, a spring compression arm (5) and a spring compression mechanism (8) directly connected to the large eccentric portion, and one end of the spring compression member It consists of a spring 11 connected to the mechanism 8 and the other end connected to the motor. The guide arm 5, which is manufactured with one end fixed to the small eccentric, has a channel 15 at the other end. Guide support ball 16 is connected to the motor body is coupled to the channel (15). When the crankshaft rotates and the motor is started, the eccentric 6 moves with the support of the connecting rod 4. By this movement, the center of the connecting rod 4 is changed; The assembly and spring compression mechanism 8 which promotes the compression of the spring 11 are thus rotated around the axis in proportion to the amount allowed by the compression arm 5 and supported at the spring compression axis or at another suitable position. The compression spring assembly includes a large eccentric portion and a guide arm fixed thereto, a sliding roller bearing for a spring compression mechanism, a spring compression joint 12, a spring 11, a crankshaft rotation circumference 10, and a small size. The eccentric part guide support roller 15 and the spring compression mechanism 8 are comprised.

When the piston is at its bottom dead center, the spring is fully compressed. When the crankshaft 20 begins to rotate clockwise, the piston 2 presses the connecting rod 4 downward from the bottom dead center with the pressure generated by the gas expanded in the cylinder 1. This pressing operation is additionally made by the compression spring 11; The compression spring is supported by the compression arm bracket and presses the large eccentric portion downward by the compression arm 5. These two effects act on the small eccentric 6 in the large eccentric 5, and the crank peg 7 in the small eccentric 6 is pressed downward by an additional moment arm. Thus, the rotation moment applied to the crankshaft 20 is strengthened due to the effect of the additional moment arm on the crank peg 7.

The pressure of the piston 4 acting on the connecting rod 4 is greater than the pressure acting on the piston 2 in an angular position due to the eccentricity in the connecting rod 4. In other words, the pressure for rotating the crankshaft 20 is high, and the moment arm (length t) is long; This provides a significant amount of positive gain. Further, the fact that the position of the spring acting point acting on the spring arm 5 from the spring compression mechanism 8 while fixing the spring 11 is fixed, and the position of the acting point acting on the crank peg 7 is variable. Due to; The spring 11 is compressed to a much greater moment. After tightening the spring 11, the moment arm remains constant relative to the support point, while the other arm is much shorter than the arm that tightens the spring. This condition offers many advantages when selecting moment arms and springs.

Since the crankshaft and the cylinder 1 and the piston drive axis are completely different, this difference gives the piston 2 a very effective pressure action in the positive direction inside the cylinder 1. In other words, the deviation between the crank peg center and the connecting rod center keeps the piston 2 higher than the position of the crank peg 7, thereby making the pressure action much more effective by the pressure generated by the expansion in the cylinder.
