Description

Technical Field

[0001] The present invention relates to the field of torque limiting vibration dampers for new energy vehicles, and in particular to an integrated torque limiting vibration damper device with adjustable centering. Background Art

[0002] New energy passenger vehicles have emerged as a new force and have made a great splash in the passenger vehicle market. Between the high travel costs of traditional fuel vehicles and the range anxiety of new energy pure electric vehicles, hybrid vehicles are often more popular with users. Since hybrid vehicles use new energy transmissions and abandon traditional gearboxes and clutches, during the operation of the engine, problems such as transmission system vibration and overload need to be overcome by using torque limiting dampers.

[0003] Traditional torque-limiting shock absorbers are generally directly connected to the flywheel and only serve to transmit torque, reduce vibration, and provide overload protection. Traditional torque-limiting shock absorbers have a low degree of integration, which affects the assembly efficiency of the entire vehicle. However, some types of integrated products have begun to appear on the market, but due to space and volume limitations, it is difficult for integrated torque-limiting shock absorbers to achieve the centering effect of the disc hub. Secondly, after the vehicle is used, the integrated torque-limiting shock absorber will slip relative to the mounting bolts, which greatly affects the disassembly of the integrated torque-limiting shock absorber. In addition, most products use cast iron flywheels, which make it difficult to adjust the inertia at the engine output end, and the cost of adjustment is also relatively high.
