Product Description

SD16 Bulldozer Torque Converter 16Y-11-20000 Turbine in stock

Shantui Bulldozer Sd16 Sd16l Torque Convertor Turbine 1

Bulldozer drive system type is divided into Mechanical transmission, hydraulic mechanical transmission system (hydraulic torque converter), there are also a few hydraulic transmission systems. Here we mainly introduce the structure and principle of hydraulic transmission system:

Drive connection principle
The Pump wheel in the pump wheel assembly is connected by a bolt and a drive housing, and the drive gear is connected by a bolt and a drive housing. The drive gear is inserted directly into the ring gear of the Engine flywheel, so the pump wheel rotates with the engine. The guide wheel is connected by a bolt and a guide hub, and the guide hub is connected by a spline and a guide wheel seat, and the guide wheel seat is connected by a bolt and a torque converter case, so that the guide wheel and the torque converter case are not rotated together. The turbine and turbine hub are riveted together with rivets and connected to the turbine output shaft. The turbine output shaft is coupled via splines and couplings to transfer power to the subsequent drive train. The pump wheel rotates with the engine, the power is input, the guide wheel does not rotate, the turbine rotates, and the power output is independent of each other, and the gap between the wheels is about 2 mm.

The pump wheel, the turbine and the guide wheel are themselves composed of a plurality of blades, which are called cascades, and the blades are formed by curved shapes and have a complicated shape. When the torque converter is working, the cascade needs to be filled with oil. When the pump wheel rotates at high speed, the oil in the pump wheel cascade flows outward along the curved surface under the action of centrifugal force, and is directed at the exit of the cascade. The turbine cascade exits then centripetally flow along the turbine cascade surface and from the turbine cascade outlet to the guide vane inlet, through the guide vane cascade and back to the pump impeller. The circular space composed of the pump wheel, the turbine and the guide vane cascade is called a circular circle. Due to the design of the shape of the turbine cascade surface, it is determined that the turbine and the pump wheel rotate in the same direction. In this way, the oil in the circle of the converter cascade, on the one hand, rotates in the cycle circle, and on the other hand rotates with the pump wheel and the turbine, thus forming a complex spiral motion, in which the energy is pumped from the pump The wheel is passed to the turbine. The turbine load is determined by the dozer load. The load of the bulldozer is transferred by the blade to the track travel system and then to the final drive, steering clutch, central drive, transmission and coupling assembly, and ultimately to the torque converter turbine. When the turbine load is small, the rotation speed is fast; when the load is large, the rotation speed is slow. When the bulldozer is unable to move due to overload, the speed of the turbine also drops to zero, which becomes the braking state of the turbine. At this time, because the turbine stops rotating, the oil injected by the pump vane cascade passes through the turbine cascade to drive the guide wheel with the greatest impact, and is converted into pressure in the non-rotating guide vane cascade. The turbine increases the torque of the turbine. The increased torque is in the same direction as the turbine. At this time, the turbine output torque is the maximum, which is 2.54 times the pump torque. As the load increases, the speed of the turbine gradually decreases and the torque gradually increases. This is equivalent to a stepless speed change in a continuously variable transmission. This stepless torque-changing performance is matched with a planetary gear-type power shift transmission that is easy to handle and has fewer gears, enabling the bulldozer to achieve superior traction performance.

The torque converter works on hydraulic power. When the oil flows in the cascade, energy is consumed due to impact and friction, and the oil is heated, so the transmission efficiency of the torque converter is low. The best torque converter at home and abroad has a maximum efficiency of 88%. When the turbine of the torque converter stops rotating due to the overload of the bulldozer, all the energy transmitted from the pump wheel is converted into heat and consumed, and the torque converter efficiency is zero. In order to improve the transmission efficiency of the torque converter, it is necessary to grasp the load of the bulldozer so that the turbine has an appropriate speed and the bulldozer has an appropriate speed; that is, when the bulldozer is unable to move due to excessive load, it is necessary to reduce the load in time. Cut the blade or change from II to I.

When the torque converter is working, the oil will leak and heat. It is required to replenish the inside of the torque converter in time and replace the heated oil with cooling to form a cooling circulation system.
