The invention belongs to the technical field of vibration reduction flywheels, and particularly relates to a vibration reduction flywheel, a power assembly and a vehicle. The vibration reduction flywheel comprises a first rotating part, a second rotating part and a third rotating part, and the first rotating direction is opposite to the second rotating direction. When the second rotating piece rotates in the first rotating direction relative to the third rotating piece, the first rotating piece rotates in the first rotating direction relative to the third rotating piece, and the sum of the friction force between the first rotating piece and the third rotating piece and the friction force between the second rotating piece and the third rotating piece is first friction force; when the second rotating part rotates in the second rotating direction relative to the third rotating part, the first rotating part keeps static relative to the third rotating part, a second friction force is generated between the second rotating part and the third rotating part, and the first friction force is larger than the second friction force, so that the reverse damping is increased under the condition that the forward damping is not adjusted; the increased reverse damping can reduce the reverse dragging torque of the driving motor to the engine, and a better damping effect is achieved.
本发明属于减振飞轮技术领域,特别是涉及一种减振飞轮、动力总成及车辆。减振飞轮包括第一转动件、第二转动件及第三转动件,第一旋转方向和第二旋转方向相反;在第二转动件相对第三转动件沿第一旋转方向转动时,第一转动件相对第三转动件沿第一旋转方向转动,第一转动件与第三转动件之间的摩擦力与第二转动件与第三转动件之间的摩擦力之和为第一摩擦力;在第二转动件相对第三转动件沿第二旋转方向转动时,第一转动件相对第三转动件保持静止,第二转动件与第三转动件之间产生第二摩擦力,第一摩擦力大于第二摩擦力,使得在不调整正向阻尼大小的情况下增加反向阻尼,增大后的反向阻尼能够减小驱动电机对发动机的反拖力矩,达到更优的减振作用。
