Abstract

The invention discloses a torsion damper with a torsion spring. The torsion spring is obtained by deforming a hollow torsion bar spring, and the torsional deformation center axis of the torsion spring is coaxial with the power transmission rotation center of the torsion damper. The torsion spring is formed by stacking elastic materials in the axial direction or the radial direction, the torsion spring is in a corrugated pipe shape when the elastic materials are stacked in the axial direction, and the torsion spring is in an annular wave shape from inside to outside when the elastic materials are stacked in the radial direction. The torsion damper can be applied to a clutch driven disc or a dual-mass flywheel. As the hollow torsion bar spring formed in a stacking mode is introduced to serve as an elastic damping element of the torsion damper, the space utilization rate is high, and the torsional damping rotation angle is large; meanwhile, the torsion damper is simple in structure, low in cost, light in weight and good in batch production uniformity; the torsion spring is easy to machine and form when made of polymer materials or polymer-based composite materials, and cost is lower.
