Abstract

The invention discloses a two-planetary gear mechanism. The two-planetary gear mechanism comprises an outer gear disc, the outer gear disc is respectively meshed with two first planetary gears, the outer gear disc is respectively rotatably connected with the two first planetary gears, the two first planetary gears are respectively rotatably connected with two first fixed shafts, the first fixed shafts are fixedly connected with the inner side walls of limiting discs, and the inner side walls of the limiting discs are fixedly connected with second fixed shafts, the second fixed shafts are meshed with second planetary gears, and the second fixed shafts are rotatably connected with the second planetary gears; the second planetary gears are rotatably connected with second sun gears, the secondsun gears are meshed with the second planetary gears, the second sun gears are fixedly connected with first vertical cylinders, and the limiting discs are fixedly connected with second vertical cylinders. The two-planetary gear mechanism provided by the invention has the beneficial effects of reducing the weight of parts, and the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a two-planet gear mechanism. Background technique [0002] The speed change gear mechanism of the 6AT transmission is composed of a simple planetary gear mechanism and a compound planetary gear mechanism. The simple planetary gear mechanism is usually fixed by the sun gear, the ring gear is used as the input, the planetary carrier is used as the power output, and the planetary carrier transmits the power. For the compound planetary gear mechanism in the rear row, the speed ratio change of the gear position is realized through the switching of the rotating parts of the planetary gear. Due to the large number of planetary gears, the weight of transmission components increases and the manufacturing cost increases. [0003] Therefore, it is necessary to provide a new two-planetary gear mechanism to solve the above technical problems. Contents of the invention [0004] In or...
