Embodiment 1

[0017] Example 1, such as figure 1 As shown, a shock absorber assembly includes a shock absorber mounting shaft 7, a spoke 8 and a hub 6, and a pulley 4 acting as an inertia disk is set outside the hub 6 through a second-stage rubber ring 5. On the pulley 4 Set the second stage inertia ring 3. The front end of the hub 6 is also provided with a first-stage rubber ring 2 and a first-stage inertia ring 1 in parallel. The pulley 4 , the second-stage inertia ring 3 and the first-stage inertia ring 1 can rotate mutually between the hub 6 .

Embodiment 2

[0018] Embodiment 2, the second-stage inertia ring 3 and the pulley 4 are integral. All the other are with embodiment 1.

Embodiment 3

[0019] Embodiment 3, in order to optimize the structure and reduce weight, the spokes are trapezoidal and have weight reducing holes on them. There are three lightening holes, which are evenly distributed in the circumferential direction of the spokes. All the other are with embodiment 1 or 2.

Abstract

The invention discloses a vibration damper assembly, which comprises a shock absorber mounting shaft, a spoke and a hub. A belt wheel having the function of an inertia disc is arranged outside the hub through a second-stage rubber ring, and is provided with a second-stage inertia ring. The shock absorber assembly is characterized in that the front end of the hub is connected in parallel with a first-stage rubber ring and a first-stage inertia ring. In order to eliminate the vibration caused by first-order vibration frequency of a crank, the first-stage rubber ring and a first-stage inertia ring form a torsional vibration damper consistent with the first-order vibration frequency of the crank. The first-stage inertia ring is arranged in the second-stage inertia ring. Because parallelly-connected two-stage vibration damper is adopted, and two stages of inertia rings are used, the working frequency of the vibrator damper is effectively reduced, the hardness of the rubber can be controlled in a certain range, and the service life of the crank of an engine is improved and the vibration and noise of the engine are reduced under the action of the vibration damper consisting of the two stages of inertia rings.

Description

technical field [0001] The invention relates to a torsional shock absorber for an engine crankshaft, which can improve the torsional vibration of the crankshaft of the automobile engine and improve the ride comfort of the automobile. Background technique [0002] With the continuous innovation of automobile engine technology, the requirements for engine torque, power and NVH are constantly increasing, which puts higher requirements on the vibration of the engine. How to reduce the vibration of the engine is one of the important contents in the design of the engine crankshaft system. A common way to reduce crankshaft vibration is to install a shock absorber at the front end of the crankshaft. At present, the rubber damping single-stage torsional shock absorber is widely used in the crankshaft system of automobile engines, and its damping value is relatively small. In order to meet the vibration damping requirements, the frequency of the rubber needs to be increased to achiev...
