Hydraulic synchronization transmission

Abstract

The invention discloses a hydraulic synchronous gearbox of efficiently realizing constant-power stepless speed regulation and stepless torque conversion, which is characterized by comprising a bull gear, wherein the bull gear is engaged with a sun wheel through a planet wheel; the planet wheel is connected with a scoop wheel; a planet carrier and a box body are connected through a liquid viscous brake; an input shaft is connected with the sun wheel; and an output shaft is connected with the bull gear. The hydraulic synchronous gearbox can realize constant-power stepless speed regulation and stepless torque conversion of power drive and soft starting with average efficiency of about 95 percent, and efficiency of the lowest rotating speed and the highest rotating speed of about 99 percent, can be widely applied to automobiles, engineering machinery, mineral machinery, electric plants, steel plants and chemical engineering machinery, has excellent performances on stepless speed regulation, stepless torque conversion and soft starting, and has greater advantage in solving the problem of heavy-load starting of high-power load.

Description

Technical field: [0001] The invention belongs to the technical field of hydraulic transmission, in particular to a hydraulic synchronous transmission capable of realizing constant power stepless speed regulation and stepless torque conversion with high efficiency. Background technique: [0002] Existing power transmission schemes for constant power stepless speed regulation and stepless torque conversion mainly include various friction stepless speed governors, metal belt stepless speed governors, and hydraulic torque converters. The power of the friction stepless speed governor can rarely reach more than 100 kW, and the efficiency is between 40% and 90%. The transmission torque of the metal belt stepless speed governor rarely exceeds 300Nm, and the efficiency is between 70% and 92%. The hydraulic torque converter transmits a large power, but the highest efficiency rarely exceeds 85%, and the range of high efficiency is not wide, which is an inefficient transmission method; ...

Problems solved by technology

[0003] I invented a "hydraulic synchronizer" in August 2006. The patent number is 2006100698771. It is equipped with an input shaft, an output shaft, a rotating body, a bucket wheel, a planetary wheel, and a fusible plug. Composed of left and right end covers, there is a bracket in the rotating body, the bucket wheel is supported on the left end cover and the bracket of the rotating body through the bucket wheel shaft, the planetary wheel is cantilever supported on the bucket wheel shaft, the planetary wheel and the sun gear are internally meshed, and the input shaft is connected to the rotating body Connection, the sun gear is connected with the output shaft, the shortcoming is that the box oil enters the bearing seat through the oil circuit and the throttling device, and then enters the rotating body to participate in the work and adjust the time of the soft start. The shortcoming is that it cannot be adjusted steplessly speed and stepless torque
