bulldozer hydraulic

bulldozer hydraulic cylinder pump impeller wheel assembly connected by bolts and drive housing, a drive gear connected by bolts and drive housing. Drive gear directly into the engine flywheel circle, so the pump wheel rotates with the engine. Guide wheels connected by a bolt and guide wheel, guide wheels connected by a spline and guide wheel base, the guide wheel base and connected by bolts and converter housing, so the guide wheel and the converter case together, are not rotated. Turbines and turbine hub riveted together with rivets, and then through the splined output shaft and the turbine, the turbine output shaft splines and coupling connection through the power transmission to subsequent transmission. Pump wheel rotates together with the engine, the power input, the guide wheel does not rotate, rotation of the turbine, the power output of between three independent, inter-wheel gap of about 2mm.
swamp hydrostatic dozer cylinder pump wheel, turbine wheel itself by a number of guide vanes, to be known cascade blades constituted by the song, was a complex shape. Torque converter at work, Cascades is full of fluid required in high-speed rotating impeller, impeller blades of fluid under the action of centrifugal force along the surface flow outward toward the exit of Cascades turbine cascade exports flow to the heart and then make, and from turbine cascade outlet guide vanes exit gate of imports through the guide wheel cascade flows back into the pump wheel turbine cascade along the surface. Impeller, circular space turbine cascade consisting of guide wheel, called torus. Due to the curved shape of turbine cascade design, determine the turbine and the pump wheel rotates in the same direction. Thus, the torque converter cascade loop round the oil, on the one hand in a circle rotation cycle, on the one hand and with the pump and turbine rotation, thereby forming a complex spiral movement, this movement, the energy from the pump passed to the turbine wheel.
