Hydraulic torque converter device with combined vibration absorption function

Abstract

The invention discloses a hydraulic torque converter device with the combined vibration absorption function, which includes a right cover plate, a pressure plate, a turbine output shaft, a sealing ring, a flange plate, a right bearing, a turbine output shaft long sleeve, a pump wheel bearing supporting seat, a pump wheel bearing, a guide wheel bearing, a guide wheel supporting seat, a guide wheelhub, a pump wheel inner ring, a guide wheel inner ring, a rubber gear, a pump wheel casing, a turbine inner ring, a pump wheel housing, a turbine casing, a support plate, a torsional vibration damper,a clutch driven plate, a clutch driving plate, a piston, a turbine flange, a turbine hub, a return spring, a guide wheel supporting seat left positioning short sleeve, a turbine output shaft short sleeve and a guide wheel supporting seat bearing positioning sleeve. The hydraulic torque converter device can realize the effect of reducing the system torsional vibration under the three working conditions of the low-speed working condition, the transitional working condition of the transition from the low-speed working condition to the high-speed working condition, and the high-speed working condition, can reduce the system torsional vibration to the maximum, and realizes the purposes of stable transmission and uniform loading.

Description

Technical field [0001] The invention relates to the technical field of hydraulic transmission, in particular to a hydraulic torque converter device with a comprehensive damping effect. Background technique [0002] As a source of power, the engine is also a source of vibration. The vibration comes from the reciprocating work between the engine piston and the cylinder. The normal working speed of the engine is as high as about 2000rpm, and the cylinder will have hundreds of times of intake-compression-work. -Exhaust process, this will cause irregular torque output of crankshaft speed, irregular vibration produced by the engine will exist in the entire transmission system, and in severe cases, it will cause the drive shaft to break. [0003] The usual way to solve the irregular vibration of the engine is to use a torsional shock absorber. The torsional shock absorber can store the irregular excitation of the engine through a torsion spring and then release it, which is equivalent to ...

AI Technical Summary

Problems solved by technology

[0004] Due to the different installation positions of these two damping devices, the final damping effect will be different. The traditional torsional damper is installed after the engine crankshaft and before the flywheel disc. This damping method will only To reduce part of the vibration from the engine crankshaft, the vibration after the flywheel is difficult to reduce. Using a hydraulic torque converter for vibration reduction can reduce the vibration before the flywheel of the engine, but it cannot change the vibration caused by irregular loads
