Embodiment Construction

[0014] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] see image 3 and Figure 4 , a dual-mass flywheel 1, including a driving hub 11, an inertia ring 12, the driving hub 11 and the inertia ring 12 are riveted together, not only that, but blind holes 13 are also provided on the contacting surfaces of the driving hub 11 and the inertia ring 12 And 14, the blind hole 14 of the inertia ring 12 is provided with an insert block 15, and an elastic member 16 is arranged between the insert block 15 and the inertia ring 12 at the bottom of the blind hole. To provide the elastic recovery force of the plug 15 . In this embodiment, there are multiple blind holes 13 and 14 on the driving hub 11 and the inertia ring 12, for example, there are six. On the driving hub 11 or the inertia ring 12, the ...

Abstract

The invention relates to a dual-mass flywheel, which includes a driving hub and an inertia ring. When the dual-mass flywheel is in the first state corresponding to no deformation of the riveted part, the plug is in a pre-compressed state due to the resistance of the driving hub; once the riveted part Slight deformation occurs, corresponding to the second state of the dual-mass flywheel at this time, the driving hub and the inertia ring rotate slightly in the circumferential direction, so that the plug pops out of the blind hole of the inertia ring and enters the blind hole of the driving hub. In the dual-mass flywheel, there is not only the original riveted connection of the riveted parts, but also a new plug-in connection, which can avoid further deformation or breaking of the riveted parts, thereby avoiding noise and damage to the gearbox.

Description

technical field [0001] The present invention relates to dual mass flywheels. Background technique [0002] Existing dual mass flywheel 1', see figure 1 and figure 2 As shown, the driving hub 11' is riveted with the inertia ring 12'. When performing strength tests on the riveted part 13', we found that the impact torque caused by resonance and other misoperations will act on the riveted part, causing the riveted part to easily break out. Plastic deformation and even breakage easily, causing noise and increasing the risk of gearbox damage. Contents of the invention [0003] The problem solved by the invention is the problem that the riveting parts are easily deformed or broken. [0004] In order to solve the above problems, the present invention provides a dual-mass flywheel, including a driving hub and an inertia ring, wherein blind holes are provided on the opposite surfaces of the driving hub and the inertia ring, and the blind holes of the inertia ring An insert is ...
