Embodiment Construction

[0016] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0017] The characteristic of the existing gear transmission is that the gear teeth are embedded by equal action and reaction torque transmission. According to the most basic law of energy conservation in physics, as long as the gear processing technology has a certain precision, if <1% of the frictional heating energy loss is ignored (the same for the following text), the mechanical energy at the input end of the gear is equal to the mechanical energy at the output end of the gear. The transmission line speed between the two gear teeth is equal, and the product of the torque and the gear speed is equal to the power.

[0018] See attached figure 1 , for the sun gear 3, planet carrier 4 and ring gear 1 rotating elements of a single planetary gear row. Only when one component inputs a fixed power and rotational speed, and one component is fixed and does not rot...

Abstract

The invention discloses a novel automatic gearbox of a stepless gear and is applicable to gearboxes of all transport tools such as vehicles, airplanes, ships and warships, and all mechanical machining equipment connecting power variable-transmission systems. Compared with existing gearboxes, the novel automatic gearbox of the stepless gear is characterized by mainly structurally comprising planetary gear rows or differential gear sets, or consisting of the planetary gear rows and the differential gear sets. The principle of the automatic gearbox of the stepless gear includes related various gear rotating components in the planetary gear rows or differential gear sets do not idle. The novel automatic gearbox of the stepless gear applicable to the field of traffic vehicles is mainly composed of planetary gear rows serially coaxially connected. A sun gear of one planetary gear row is used as a power input component, a planetary gear carrier and an inner gear ring are respectively synchronously connected with the sun gears of the adjacent planetary gear rows and the planetary gear carrier, the inner gear ring is used as a power output component, and the automatic gearbox of the stepless gear is formed under the condition of meeting the requirement that various gear rotating components do not idle.

Description

technical field [0001] All kinds of mechanical machine tools and equipment include manual or automatic transmissions configured for all power transmission systems of automobiles, aircraft, and ship vehicles. Background technique [0002] At present, there are gearboxes configured with power output variable speed transmission systems of all mechanical machine tools including transportation vehicles at home and abroad. The transmission structure, manufacturing process and service conditions of the vehicle configuration are the most complex. From a global perspective, the main automatic transmissions are AMT (automatic manual), AT (automatic), CVT (continuously variable transmission) and DCT (dual clutch transmission), each of which has its own advantages and disadvantages. The energy-saving effect of AT is poor, but the comfort is good, the reliability of components is high, its production history is long, and its application range is wide. The CVT steel belt has limited tor...
