Problems solved by technology

The currently popular six-speed planetary automatic transmission has a relatively small transmission ratio range and cannot meet the requirements of the transmission ratio. Therefore, it is necessary to provide a nine-speed transmission to meet the vehicle's requirements for gear positions.
[0003] The inventor finds through long-term observation and research that the existing automatic transmission for vehicles has the following disadvantages: 1, the step ratio between adjacent gears is large, the transmission ratio range is small, and uneconomical
2. During the working process, the vibration is relatively large, which affects the normal operation of the transmission, poses safety hazards, and costs a lot of maintenance
3. The response speed of shifting is slow, the frustration of shifting is obvious, and the car's handling is poor

Abstract

The invention provides a nine-stage transmission which comprises planet rows, an input component, an output component, transmission components, brakes and clutches. The input component and the output component are arranged at the two ends and connected with a corresponding input shaft and a corresponding output shaft respectively. The planet rows comprise the planet row PGS1, the planet row PGS2, the planet row PGS3 and the planet row PGS4. The transmission components comprise the transmission component (3), the transmission component (4), the transmission component (5), the transmission component (6) and the transmission component (7). The brakes comprise the brake B1, the brake B2, the brake B3 and the brake B4. The clutches comprise the clutch C1 and the clutch C2. The transmission has the beneficial effects of having multiple gears and being good in fuel economical efficiency, small in size and light.

Description

technical field [0001] The invention relates to a transmission device, in particular to a nine-stage transmission of an automobile drive system. Background technique [0002] In the automatic transmission for vehicles, the internal combustion engine and other power are transmitted to the input shaft of the 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 and right drive wheels through the differential. Automatic transmissions generally consist of multiple planetary rows, brakes and clutches. The currently popular six-speed planetary automatic transmission has a relatively small transmission ratio range and cannot meet the requirements of the transmission ratio. Therefore, it is necessary to provide a nine-speed transmission to meet the gear requirements of the vehicle. [0003] The inventor finds through long-term observation and research that the existing...
