A new type of power transmission device

Abstract

The invention discloses a new type of power transmission device, which comprises a piston connected with a piston connecting rod, and the other end of the piston connecting rod is connected with an integrally formed clutch inner gear frame which can move left and right relative to the piston, and the clutch inner gear frame consists of two pieces Clutch internal tooth plates are set at intervals. There is an annular groove on the clutch internal tooth plate. The annular groove includes two sections of straight side walls and two sections of arc transition surfaces. There are longitudinally arranged left internal teeth between the two clutch internal tooth plates. And the right internal teeth arranged longitudinally, in the annular groove, there is a gear that can mesh with the left internal tooth and the right internal tooth alternately, and the transmission shaft passing through the annular groove is provided on the gear, and the gear includes a circular arc part and a toothed part For the incomplete gear, the two sides of the gear are respectively provided with pushers that can contact the clutch inner tooth plate when the gear rotates, so as to prevent the arc part from colliding with the left inner tooth and the right inner tooth. The invention has high mechanical strength and can directly replace the crank connecting rod mechanism of the existing engine.

Description

【Technical field】 [0001] The invention relates to a power transmission device, more specifically a novel power transmission device. 【Background technique】 [0002] At present, automobile engines all use a crank-link mechanism, which has a congenital deficiency: that is, there is a mechanical dead point, which leads to insufficient utilization of work efficiency. The mechanical dead point refers to the fact that the arm length between the force point and the fulcrum is zero when the maximum pressure is generated at the moment of ignition burst after the compression stroke of the engine piston ends at the top dead center. That is: arm length = sinα (angle) × radius of rotation. Since α (angle) is zero when the piston compresses top dead center, the arm length is zero. According to the mechanical principle, the arm length is zero, and the action force not only cannot do useful work, but also produces harmful impact force on the fulcrum. Only when the angle is greater than 0°...

AI Technical Summary

Problems solved by technology

[0002] At present, automobile engines all use a crank-link mechanism, which has a congenital deficiency: that is, there is a mechanical dead point, which leads to insufficient utilization of work efficiency

Although this patented technology avoids the mechanical dead point and achieves the purpose of improving the working efficiency of the engine, the technology still has the following deficiencies: 1. This patented technology is only suitable for the remanufacturing of the complete engine (comprising the cylinder block), and cannot A direct replacement for the crank linkage of an existing engine

Due to the limitation of the current engine block structure, when replacing the crank-link mechanism of the engine and wanting to continue to use the existing engine block, the left and right internal gears on the clutch inner tooth plate are manufactured mechanically. The strength is very low, and it is easy to break from the root of the tooth, and the cost of manufacturing the complete engine is very high; 2. The gears in this patented technical solution are reversing during the process of alternately meshing with the left internal tooth and the right internal tooth Unstable, increasing the mechanical fatigue loss of the left and right inner teeth
