The invention relates to a gear transmission mechanism used for a five-gear transversely-placed automatic transmission. The gear transmission mechanism comprises an input shaft, an output shaft, a first brake, a second brake, a third brake, a fourth brake, a first clutch and a second clutch; the gear transmission mechanism further comprises a first planet row, a second planet row and a third planet row, wherein the first planet row is composed of a first gear ring, a first planet gear, a first sun wheel and a first planet carrier, the second planet row is composed of a second gear ring, a second planet gear, a second sun wheel and a second planet carrier, and the third planet row is composed of a third gear ring, a third planet gear, a third sun wheel and a third planet carrier. The gear transmission mechanism can achieve five forward gears and a reverse gear with a fewer number of planet rows, so the overall size of the gear transmission mechanism is reduced, and the gear transmission mechanism is simple in structure and easy to control; as for the three planet rows of the gear transmission mechanism, the micro-segment gears are adopted, and therefore miniaturization of planet gear mechanism transmission is easy to achieve; compared with an ordinary involute gear planet transmission mechanism, transmission efficiency of the gear transmission mechanism can be increased by about 5%.
Description
technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a gear transmission mechanism for a 5-speed horizontal automatic transmission. Background technique [0002] Automatic transmission technology can largely overcome the disadvantages of slow shifting of manual transmissions. At present, it has been widely used in the automobile industry, and the structure is also complex and diverse. However, with the development of the automobile industry, automatic transmissions have higher and higher requirements for transmission efficiency, smoothness of shifting, and overall size and weight. Compared with manual transmissions, automatic transmissions have low transmission efficiency and poor fuel economy, which are the bottlenecks encountered in the development of automatic transmissions. [0003] At present, for horizontal automatic transmissions, almost all gear transmission mechanisms of automatic transmission...
