Abstract

The invention discloses a five-speed automatic gearbox of a planetary gear. The gearbox comprises front sun wheels, rear sun wheels, front gear rings, rear gear rings, front planetary gears, rear planetary gears, front planetary carriers, rear planetary carriers, a piece-type brake, a first belt brake, a second belt brake, a first clutch, a second clutch, a third clutch, a fourth clutch, a power input shaft and a power output shaft, wherein the power input shaft is connected with a hub of the second clutch, a hub of the first clutch and a hub of the fourth clutch into a whole; the power output shaft is connected with the rear row of planetary carriers and the front row of gear rings into a whole; the hub of the first clutch is connected with a front row of solar wheels into a whole; the hub of the fourth clutch is connected with the rear row of sun wheels into a whole; the hub of the third clutch is connected with the rear row of gear rings into a whole; and the hub of the second clutch, the hub of the third clutch, the hub of the piece-type brake and the front row of planetary carriers are connected into a whole. With the adoption of the five-speed automatic gearbox of the planetary gear, the defects that the traditional automatic gearbox is complex in structure and swollen in volume are overcome, so that the novel five-speed automatic gearbox of the planetary gear is provided.

Description

technical field [0001] The invention relates to an automatic transmission, in particular to a five-speed planetary automatic transmission. Background technique [0002] Most modern car automatic transmissions use planetary gear mechanisms, which are composed of 2-3 rows of planetary gear mechanisms and related actuators. The single-row planetary gear mechanism is composed of a sun gear, a ring gear, and a planetary carrier, and there are planetary gears on the planetary carrier; the actuators mainly include clutches and brakes. Constraints can form different gears. [0003] The traditional automatic transmission has the characteristics of complex structure, high cost, difficult maintenance and low transmission efficiency. With the rapid development of automobile technology, it is urgent to develop some automatic transmissions with simple structure, low cost, convenient maintenance and high transmission efficiency. Contents of the invention [0004] In view of the abo...
