Problems solved by technology
The flywheel of this patent generally needs to be connected in parallel with a starting gear to start the flywheel in the current practice. Generally, the starting gear and the flywheel are rigidly connected, but this will cause a rigid collision when starting, resulting in damage to the flywheel and noise.

Embodiment Construction
[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0025] The damping flywheel device in the automobile engine is used to reduce the rigid collision between the flywheel body 1 and the starting ring gear 2 during the start-up process of the flywheel body 1. The vibration-damping flywheel device includes a flywheel body 1, a starting ring gear 2, a rigid connection structure and elastic body.
[0026] Specifically, as figure 1 with figure 2 As shown, the rigid connection structure is arranged between the starting ring gear 2 and the flywheel body 1, and enables the starting ring gear 2 to drive the flywheel body 1 to rotate in a circumferential direction. The rigid connection structure includes a positioning slot 11 and a rigid positioning block 3. The positioning slot 1...

The invention provides a damping flywheel device in an automobile engine, which belongs to the technical field of automobile engines and solves the technical problems of damage of a flywheel, noise and the like caused by rigid collision in starting of the flywheel in the prior art. The damping flywheel device in the automobile engine comprises a flywheel body, a starting gear ring coaxial with the flywheel body is fixedly arranged on the flywheel body, a rigid connecting structure and an elastic mechanism are arranged between the starting gear ring and the flywheel body, the rigid connecting structure enables the starting gear ring to circumferentially drive the flywheel body to rotate, and the elastic mechanism is capable of buffering the starting gear ring and the flywheel body before the starting gear ring rotates to be synchronous with the flywheel body. As the elastic mechanism is arranged between the starting gear ring and the flywheel body, rigid collision between a starting gear of a starting engine and the starting gear of a flywheel is avoided, the service life of a part is prolonged, and noise is reduced. Besides, an elastic block and a buffer spring function in double damping and buffering.
Description
technical field [0001] The invention belongs to the technical field of automobile engines, and relates to a vibration-damping flywheel device in an automobile engine. Background technique [0002] A flywheel is an energy storage device for an internal combustion engine, and the greater the moment of inertia, the more energy it can store. And the bigger the moment of inertia is, the harder it is to start. There is also a starter gear on the flywheel. When the internal combustion engine starts, the starter gear pops up and meshes with the flywheel starter gear, and the engine is run through the speed transmission. [0003] In the above process, because of the uncertainty of the rotation position of the flywheel every time the engine stops, when the starter drives the starter gear to rotate, the starter starter gear will collide with the flywheel starter gear. Due to the large inertia of the flywheel, if this kind of impact cannot be well buffered, it will cause damage to the...
