Embodiment 1

[0037] The nine-speed planetary automatic transmission provided by the invention is suitable for road wheeled vehicles. Among them, each planetary row is arranged in order, and each planetary row is connected by a connecting member. The input shaft is connected to the input member 1, which is generally the turbine shaft of the hydraulic torque converter, and is used to transfer the power of the engine through the hydraulic torque converter. to the planetary automatic transmission. The output shaft is connected with the output member 2, and the power is transmitted to the front and rear axles or the left and right drive wheels through the transfer case or differential. The planetary automatic transmission is completely symmetrical with respect to the center of rotation, figure 1 The lower part of the center of rotation is omitted in , and will not be explained in the following description.

[0038] Such as figure 1 As shown, the nine-speed planetary automatic transmission in...

Abstract

The invention provides a nine-gear planet automatic transmission. The nine-gear planet automatic transmission comprises four planet rows, an input component, an output component, five connection components, four brakes and two clutches. The input component and the output component are mounted at the two ends and connected with an input shaft and an output shaft correspondingly. Thus, the planet automatic transmission has multiple gear stages including nine forward gears and one reverse gear, and the usage requirements for highway wheeled vehicles are met better.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of vehicle transmission, and in particular relates to a nine-speed planetary automatic transmission for road vehicles. [0003] Background technique: [0004] As a planetary automatic transmission for road wheeled vehicles, the internal combustion engine and other power are transmitted to the input shaft of the planetary automatic transmission through the hydraulic torque converter. After shifting according to the current gear, the power is output from the output shaft and transmitted to the left through the differential. , the right drive wheel, and most of the transmission is composed of multiple planetary rows, brakes and clutches. At present, the existing Chinese patent announcement number CN20120402156, the announcement date is February 06, 2013, and the name is a seven-speed planetary automatic transmission. A kind of automatic speed change method with poor economy, for this reason, need to fin...
