Problems solved by technology
[0008] Even if the combination of silicone oil and rubber is used for vibration reduction, the vibration reduction effect of the silicone oil rubber shock absorber is not ideal, which causes the temperature of the engine to be extremely unstable during operation, and may rise to a high level, resulting in heat dissipation of the silicone oil The ability of the shock absorber to decline, or the rubber's damping ability to decline, which in turn leads to a further decline in the damping ability of the shock absorber, and enters a vicious circle

The invention discloses an engine and a shock absorber thereof. The shock absorber of the engine comprises a shock absorber body externally sheathing a crankshaft, a coasting body assembly and elastic components, wherein the coasting body assembly and the elastic components are arranged in the shock absorber body; the coasting body assembly comprises at least two coasting bodies with different rotation inertias; each elastic component is connected between the coasting bodies to cause the two adjacent coasting bodies to have a relative-rotation degree of freedom within a preset angle. The rotation inertias of different coasting bodies are different, so that the coasting bodies have different sensibilities on vibration, and the connection of the elastic components causes the two adjacent coasting bodies to have the relative-rotation degree of freedom within the preset angle. Therefore, one part of vibration energy can be stored in the elastic components when each coasting body rotates so as to achieve a purpose of alleviating vibration.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine and a shock absorber thereof. Background technique [0002] The vibration damping performance of the engine is an important index to measure its working performance, including the torsional vibration of the crankshaft under the action of the periodically changing gas pressure and reciprocating inertia of the engine. At present, in order to reduce the torsional vibration of the engine crankshaft, the method of putting a shock absorber on the crankshaft is adopted, and the following kinds of shock absorbers appear on the market. [0003] Rubber shock absorber: through the cushioning performance of rubber, the disadvantage is that the damping and elasticity of rubber are extremely sensitive to temperature changes, and the performance is extremely unstable. [0004] Silicone oil shock absorber: A large amount of heat will be generated during the operation of a high-power e...
