Abstract

The invention belongs to the technical field of hydraulic torque converters, and discloses a turbine locking hydraulic torque converter and engineering machinery. The turbine locking hydraulic torque converter is used in engineering machinery and is mounted between an engine and a transmission in the engineering machinery. The turbine lockup hydraulic torque converter comprises a pump wheel, a turbine, a guide wheel assembly and a lockup clutch. Wherein the pump wheel is in transmission connection with the engine, and the pump wheel rotates to drive the turbine to rotate by taking liquid as a medium. When the engineering machinery performs shoveling operation, the lockup clutch is unlocked to ensure that the engineering machinery has enough power output; and when the engineering machinery finishes working and enters transportation operation, the lockup clutch locks to lock the pump wheel and the turbine into a whole, the pump wheel and the turbine have the same rotating speed, hydraulic transmission is converted into mechanical transmission, and the transmission efficiency is close to 100%. According to the turbine locking hydraulic torque converter, two working conditions of power and speed are considered, so that the working efficiency and the oil consumption performance of engineering machinery are greatly improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic torque converters, in particular to a turbo lock hydraulic torque converter and engineering machinery. Background technique [0002] The hydraulic torque converter is a hydraulic machine that changes the transmission torque through the change of the kinetic energy of the liquid. Compared with the general mechanical transmission, the hydraulic torque converter has the characteristics of soft transmission performance. The hydraulic torque converter is installed between the engine and the gearbox, and uses the flow of liquid to smoothly transmit the torque of the engine to the gearbox, which can effectively attenuate the torsional vibration and dynamic load of the engine and transmission system, and make the construction machinery equipped with this component The vehicle has good starting performance, stability and automatic adaptability to external loads. The existing hydraulic torque converters ...
