The utility model relates to a dual mass flywheel with a spring bidirectional protection function, which comprises a first-stage mass (1) and a force transmission sheet (3), at least one first limiting groove and at least one second limiting groove are arranged on the force transmission sheet (3), and the first limiting groove and the second limiting groove respectively face the forward rotation direction and the reverse rotation direction of the force transmission sheet (3). Limiting blocks (4) matched with the first limiting groove and the second limiting groove are arranged on the first-stage mass (1). Compared with the prior art, the arc-shaped spring is effectively protected when the arc-shaped spring is compressed in the forward direction and the reverse direction, safety is good, and the service life is long. 本实用新型涉及一种具有弹簧双向保护功能的双质量飞轮，包括第一级质量(1)和传力片(3)，所述的传力片(3)上设有至少一个第一限位槽和至少一个第二限位槽，所述的第一限位槽和第二限位槽分别朝向传力片(3)的正转方向和反转方向，所述的第一级质量(1)上设有与第一限位槽和第二限位槽匹配的限位块(4)。与现有技术相比，本实用新型在弧形弹簧被正向和反向压缩时有效保护弧形弹簧，安全性好，使用寿命长。
