Abstract

The invention provides a multi-level speed changer, and relates to the technical field of automobiles. The multi-level speed changer comprises a first planet row, a second planet row, a third planet row, a first brake, a second brake, a third brake, a first clutch, a second clutch, a transmission shaft and an output shaft. The transmission shaft is connected with the first clutch, the second clutch and a second sun gear. The first brake is connected with a first sun gear. A first gear ring is connected with a second planet carrier. A first planet carrier is connected with the output shaft. A second gear ring is connected with a third planet carrier through a fourth shaft, and the fourth shaft is connected with the first clutch. A third sun gear is connected with the third brake through a fifth shaft, and the fifth shaft is connected with the second clutch. A third gear ring is connected with the first planet carrier. The third planet carrier is connected with the second brake. The multi-level speed changer is high in efficiency, large in torque load, small in structure and occupied space and capable of being applicable to vehicles with compact structures.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a multi-stage transmission. Background technique [0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. Speed ​​changer is made up of speed change transmission mechanism and operating mechanism, and some automobiles also have power output mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears. [0003] In the prior art transmissions, three planetary gearsets are arranged directly one behind the other, with four or other shifting elements being arranged in some cases directly upstream or downstream of the coupled planetary gearset. [0004] However, this type of transmission has low efficiency, high torque load, and large structure, which cannot b...
