What are the phenomena of torque converter fracture?

The phenomenon of torque converter fracture is mainly that the torque converter has no gear; Hydraulic torque converter has weak acceleration ability and poor high-speed performance; Hydraulic torque converter has low transmission efficiency and high oil temperature. 1. Gearless torque converter Gearless torque converter means that the power transmission in the torque converter is interrupted, that is, the torque converter has no driving response when it enters any gear. 2. The hydraulic torque converter has weak acceleration and poor high-speed performance. change

What are the phenomena of torque converter fracture?

The phenomenon of torque converter fracture is mainly that the torque converter has no gear; Hydraulic torque converter has weak acceleration ability and poor high-speed performance; Hydraulic torque converter has low transmission efficiency and high oil temperature.

1. Gearless torque converter Gearless torque converter means that the power transmission in the torque converter is interrupted, that is, the torque converter has no driving response when it enters any gear. 2. The hydraulic torque converter has weak acceleration and poor high-speed performance. The fault of poor acceleration performance caused by the fault of torque converter is mainly manifested as insufficient power during acceleration, but the high-speed driving condition is normal. According to the working principle of hydraulic torque converter, when auto start or acceleration occurs, the speed difference between the pump wheel and the turbine in the hydraulic torque converter is large. At this time, under the impact of liquid flow, the one-way clutch locks the guide wheel, which makes the torque converter increase torque. If the one-way clutch is damaged and the guide wheel cannot be locked, this function will disappear and the acceleration performance will be poor. 3. The hydraulic torque converter has low transmission efficiency and high oil temperature; Low transmission efficiency of hydraulic torque converter and high oil temperature usually indicate that the engine works normally but the fuel consumption increases. Transmission and transmission oil temperature are very high, transmission oil is easy to deteriorate, and in severe cases, white smoke will appear at the oil filler. The reason may be that the engine oil in the torque converter is insufficient, or the cooling oil pipe is blocked and the thrust bearing of the torque converter is worn. As a result, the blade gap between the pump wheel, turbine and guide wheel is too large, and the liquid flow will lose some energy in the form of heat energy, which will increase the oil temperature.

The direction of oil flow in the hydraulic torque converter. In the hydraulic torque converter with guide wheel, the automatic torque converter oil flows out of the turbine, and the direction behind the guide wheel changes. When the oil flows back to the pump wheel, its flow direction becomes the same as that of the pump wheel, which strengthens the rotating torque of the pump wheel and further increases the output torque, which is why the hydraulic torque converter can increase the torque.

What is wrong with the torque converter?

The torque converter is broken, the speed of the torque converter is irregularly low, or the car can't run. The internal seal of hydraulic torque converter is damaged, which makes the liquid flow in the working chamber impact downwards; The free wheel mechanism is stuck, resulting in the locking of the guide wheel; Wear fault of free wheel; Blade of working wheel is damaged; The inlet and outlet pressure valves are damaged; Wear of hydraulic pump and insufficient oil supply; Hydraulic oil level is too low; The friction main clutch of the gearbox is faulty.

The high oil temperature of the torque converter indicates that the oil temperature gauge exceeds120 C when the machine is working, or the soup can be felt by hands. The supply pressure of the torque converter is too low. When the engine throttle is fully open, the oil pressure at the inlet of the torque converter is still lower than the standard value. It is mainly caused by the following reasons: less oil supply, and the oil level is lower than the plane of the oil suction port; Pipeline leakage or blockage; Excessive oil flows to the transmission; The oil inlet pipe or oil filter screen is blocked; The hydraulic pump is seriously worn or damaged; Improper installation of oil suction screen; Foam oil; The inlet and outlet pressure valves cannot be closed or the spring stiffness is reduced.

The torque converter leaks oil. If oil leakage is found, start the engine and check the location of oil leakage. If there is oil leakage at the joint between the torque converter and the engine, it means that the connecting bolt between the pump wheel and the pump wheel cover is loose or the sealing ring is aging. Tighten the connecting bolt or replace the O-ring. If oil is thrown at the joint between the torque converter and the transmission, it means that the connecting bolt between the pump wheel and the pump hub is loose or the sealing ring is damaged. Tighten the bolt or check the sealing ring. If the oil leaks at the oil filler or oil drain, check the tightness of the bolt connection and whether there are cracks, etc. What are the damage phenomena of hydraulic torque converter @20 19?
