A New Type of Dual-mass Flywheel Torsional Vibration Absorber

Abstract

The invention discloses a novel dual-mass flywheel torsional shock absorber, comprising: a transmission shaft; a driving flywheel; a transmission gear; a driven flywheel, coaxially sleeved on the transmission gear; The driving flywheel is transmitted to the driven flywheel; the first liquid storage chamber and the second liquid storage chamber are respectively set inside the driven flywheel and arranged symmetrically; the first rack and the second rack are movably arranged inside the driven flywheel, And are respectively meshed with transmission gears; two first pistons are respectively fixedly connected to both ends of the first rack; two second pistons are respectively fixedly connected to both ends of the second rack; wherein, the first The two ends of the liquid storage chamber and the second liquid storage chamber are respectively provided with a first piston accommodation chamber and a second piston accommodation chamber; the two first pistons are respectively matched and arranged in the two first piston accommodation chambers, and the two second pistons They are respectively matched and arranged in the two second piston accommodation chambers; the excitation device is coaxially sleeved on the outer circumference of the driven flywheel.

Description

technical field [0001] The invention belongs to the technical field of torsional vibration damping components in automobile power transmission systems, and in particular relates to a novel double-mass flywheel torsional vibration damper. Background technique [0002] With the development and application of new automotive technologies such as light-weight, low-speed, high-torque engines and passenger car diesel engines, the torsional vibration of the power train produced by the speed fluctuations of automotive engines is becoming more and more difficult to control. Traditional automobiles limit the torsional vibration of the drive train by installing a torsional shock absorber in the clutch driven disc, but due to the limitation of size and layout space, the elastic elements of the clutch torsional shock absorber are often short in length, high in stiffness, and small in relative rotation angle , resulting in poor torsional vibration damping effect, reducing the service life ...

AI Technical Summary

Problems solved by technology

In the above technical solutions, the axial dimension is large and difficult to arrange; the weight is too large to meet the lightweight requirements of automobiles; the amount of magnetorheological fluid is large, which not only increases the cost of manufacturing, but also has a relatively large impact on the processing technology and sealing technology. High requirements; electronically controlled variable inertia system is difficult to wire and other defects
