Problems solved by technology
[0003] The torsional vibration damper currently used in the market adopts a damping spring structure. To transmit a large enough torque, the stiffness of the spring is relatively large. The rigidity weakens the vibration damping effect, and it is easy to cause resonance under the excitation of the main harmonic of the engine torque

The present invention relates to the field of shock absorbers, and aims to provide a torsional vibration shock absorber. The torsional vibration shock absorber includes a connection plate, a disk hub, a rubber ring, a limit post and bolts, and the connection plate is provided with Screw holes, the disc hub is evenly provided with more than one first through hole along the circumference, the center of the disc hub is provided with a spline hole, the shape of the rubber ring is cylindrical, and the rubber ring is provided with As for the second through hole, a third through hole is provided on the limit post. The beneficial effects of the present invention are: the connection plate is connected with the flywheel of the engine, the rotating shaft of the generator is connected with the spline hole in the center of the hub, the torque of the engine is transmitted to the hub after being damped by the rubber ring, reducing the damping stiffness, Avoid resonance.
Description
technical field [0001] The invention relates to the field of shock absorbers, in particular to a torsional vibration shock absorber. Background technique [0002] Hybrid vehicles use hybrid power as energy, which can achieve high fuel economy, low exhaust emissions, and good environmental performance, which is in line with the concept of energy conservation and environmental protection. However, as a hybrid system, its powertrain transmission assembly has added components such as the main drive motor and generator to the transmission chain compared to traditional vehicles, the moment of inertia of the transmission chain has greatly increased, and the traditional vehicle has been canceled between the engine and the generator. clutch, and the engine is dragged and started by the generator, so how to effectively isolate the main harmonic excitation of the engine torque and absorb the impact energy, and improve the mechanical reliability of the system is one of the key issues of...
