Embodiment

[0017] 1. Neutral gear: only the L1 rotating clutch is combined, the turbine output shaft 19, the L1 rotating clutch, the sun gear D18, the planetary carrier D17, and the ring gear A5 rotate together as a whole, and the torque is transmitted to the intermediate shaft 16 through the ring gear A5, due to the rotation of L2 Clutches, Z2 brakes, Z3 brakes, and Z4 brakes are not combined, there is no torque output, and neutral gear is realized.

[0018] 2. First gear: combination of L1 rotary clutch and Z3 brake. After the L1 rotary clutch is combined, the turbine output shaft 19, the L1 rotary clutch, the sun gear D18, the planet carrier D17, and the ring gear A5 rotate together as a whole, and the torque is transmitted to the intermediate shaft 16 through the ring gear A5, and the intermediate shaft 16 is at the same angular velocity Rotate and drive the sun gear B14 to rotate as a whole; the Z3 brake is combined, the ring gear D10 brakes, the torque passes through the sun gear B...

Abstract

The invention discloses a high-power hydraulic variable speed transmission device, which comprises an integral torque converter and a planetary speed changer, wherein an input flywheel, a locking clutch and a power taking device are also arranged in the torque converter; four planetary row assemblies, four brakes and two rotating clutches are arranged in the planetary speed changer; all parts are connected through splines or gears; the two rotating clutches and the four brakes are used for realizing different control; the gear requirements of eight forward gears and a neutral gear can be realized; the gear number can be reduced by decreasing the number of planetary rows and the brakes. The high-power hydraulic variable speed transmission device has the advantages that the application power is great; the structure is compact; the deformation is easy; the whole machine arrangement is favorably realized.

Description

technical field [0001] The invention relates to a hydraulic variable speed transmission device used in large-scale fracturing operation vehicles in shale gas, coal bed methane and oil and gas fields, in particular to a high-power hydraulic variable speed transmission device. Background technique [0002] With the development of shale gas, coalbed methane and oil and gas fields to deep well mining, conventional fracturing equipment can no longer meet the requirements, and a large-scale fracturing equipment with high power is needed to meet the mining requirements, and high-power fracturing equipment needs The high-power hydraulic variable speed transmission that can match it, and the general power is 2000kW-2500kW. Due to the high transmission power, the general hydraulic variable speed transmission device cannot meet the requirements. In the world, only the American Shuanghuan Company has a torque converter, fixed shaft transmission and separate hydraulic transmission device...
