Embodiment Construction

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0049] Such as Figure 1-11 As shown, the present invention provides a compound adjustable transmission system torsional vibration damping device with particle damping and electromagnetic damping. The semi-active adjustable electromagnetic damper and particle are integrated in the first mass of the traditional double-mass flywheel torsional Damper, electromagnetic damper is mainly composed of permanent magnet, silicon steel sheet, coil and shell. When the coil is fed with current and moves relative to the permanent magnet, electromagnetic damping force will be generated. Changing the magnitude of the current into the coil can realize the change of damping Force, the electromagnetic damping force has a large adjustable range, fast response speed, and small size, so there will ...

Abstract

The invention discloses a compound adjustable transmission system twisting damping device with particle damping and electromagnetic damping. The device comprises a first mass flywheel, a second mass flywheel, an electromagnetic adjustable damper and particle dampers, wherein a rotor of the electromagnetic adjustable damper is detachably fixed between the first mass flywheel and a stator end cover;the particle dampers are uniformly distributed in the peripheral direction of the outer side of the second mass flywheel; the particle dampers comprise shells, damping particles and cover plates; andthe damping particles are filled in cavities formed by the shells and the cover plates. The device is simple in structure, novel and reasonable in design, convenient to realize, low in cost and highin working stability under bad environments, can greatly reduce the transmission system twisting vibration, improves the transmission system working performance, lowers the transmission noise, and ishigh in practicability and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission, in particular to a composite adjustable transmission system torsional vibration damping device with particle damping and electromagnetic damping. Background technique [0002] The torsional vibration of the shaft system of the automobile transmission system is an important vibration form of the internal combustion engine vehicle. The torsional vibration, the vertical vibration of the vehicle caused by the excitation of the road surface and the bending vibration of the transmission system are coupled with each other, which is the root of various vibration and noise problems in traditional vehicles. And this problem will lead to the reduction of the car's stability and smoothness, and may even lead to the service life of auto parts. [0003] Dual mass flywheel (Dual Mass Flywheel) is to divide the original flywheel into two parts, which includes primary flywheel, secondary flywheel and...
