Abstract

The invention relates to the continuously-variable transmission technical field, in particular to a differential coupling continuously-variable automatic transmission which comprises an input shaft, a variable speed gear and an output shaft, wherein the variable speed gear comprises a planet support, a planet bevel gear arranged on the planet support, and a first sun gear and a second sun gear arranged at two sides of the planet bevel gear respectively; the planet bevel gear is meshed with the first sun gear and the second sun gear respectively; the input shaft is connected with the first sungear, and the output shaft is connected with the second sun gear; and the side of the second sun gear is equipped with a coupler which comprises a first coupling gear and a second coupling gear, the first coupling gear is connected with the planet support, and the second coupling gear is connected with the output shaft. The differential coupling continuously-variable automatic transmission has the advantages of simple structure, small volume, low cost, strong practicability and being capable of automatically adjusting the rotating speed ratio between the input shaft and the output shaft according to the practical operating condition.

Description

technical field [0001] The invention relates to the technical field of continuously variable transmissions, in particular to a differential coupling continuously variable automatic transmission. Background technique [0002] Transmissions are mainly divided into manual transmissions and automatic transmissions according to the shifting mode, and can be divided into stepped transmissions and continuously variable transmissions according to the number of shifting stages. [0003] Traditional manual transmissions have been widely used in various speed change transmission mechanisms. Manual transmissions generally need to be used together with clutches. During the shifting process of the car, the timing of the driver cutting off and engaging the clutch is not well coordinated with the action of shifting gears, which may easily cause the engine to stall, or the gear shifting may be unstable, resulting in severe wear of the clutch. [0004] The automatic transmission can automati...
