Multi-gear planet type hydraulic gearbox transmission mechanism

The utility model discloses a multi-gear planet type hydraulic gearbox transmission mechanism, mainly comprising a lock and vibration reduction clutch assembly (A), a hydraulic torque converter (B), a power output device (5), a built-in cycloid gear pump (6), a turbine output axle (21), a planet gearbox (D), an output axle (14), a reducer assembly (E) and the like. On the basis of not increasing the numbers of the existing clutch, the brake and the planet line, the power output using seven forward gears and one backward gear is realized by the hydraulic gearbox transmission mechanism. The multi-gear planet type hydraulic gearbox transmission mechanism has features of compact structure and relatively small volume and facilitates the arrangement of the whole device.
