Problems solved by technology

[0003] There are three common types of automotive automatic transmissions: hydraulic automatic transmission (AT), mechanical continuously variable automatic transmission (CVT), and electronically controlled mechanical automatic transmission (AMT). The stutter is obvious, the fuel consumption is relatively high, and the volume and weight of the gearbox increase significantly after the number of gears increases, which not only restricts the development of AT transmissions in the direction of more gears and higher comfort, but also makes the price relatively expensive ;CVT transmission

Abstract

The invention discloses a five-gear planetary automatic transmission which comprises a shell, a central gear, an inner gear ring, planetary gears, a planetary carrier, an output shaft, a motor, a first gear tower, a second gear tower, an input shaft, a sliding frame, a driven gear, a driven pinion, a transmission gear, a driving gear, a driving pinion, a retaining piece and an electric push rod. The shell is a supporting body, the input shaft can drive the first gear tower to rotate, the first gear tower drives the second gear tower to rotate through a transmission device composed of the sliding frame, a first holding rod, the driven gear, the driven pinion, a second holding rod, the transmission gear, the driving gear, the driving pinion and the retaining piece, the second gear tower can drive the central gear to rotate, the central gear drives the output shaft to rotate through the three planetary gears, the electric push rod is used for controlling on-off of transmission between the first gear tower and the second gear tower, the motor changes the position of the sliding frame by rotating a threaded rod, and therefore gear shifting between the input shaft and the output shaft is achieved.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a five-speed planetary automatic transmission. Background technique [0002] Automatic transmission has the advantages of easy operation, comfortable driving, and can reduce driver fatigue, and has become a development direction of modern car configuration. A car equipped with an automatic transmission can automatically change speed and torque according to road conditions, and the driver can concentrate on the road traffic without being confused by the shift operation. [0003] There are three common types of automotive automatic transmissions: hydraulic automatic transmission (AT), mechanical continuously variable automatic transmission (CVT), and electronically controlled mechanical automatic transmission (AMT). The stutter is obvious, the fuel consumption is relatively high, and the volume and weight of the gearbox increase significantly after the number of gears increases, which...
