Vehicle shock absorber
By setting a spring seat and a stop in the vibration damping device, and utilizing the contact between the disc spring and the stop, the problem of damage caused by the tight contact of the arc spring under high torque input is solved, thus achieving stress relief and tight contact suppression, and maintaining the vibration damping performance unchanged.

AI Technical Summary
Technical Problem
In the prior art, when an engine with large rotational variations is subjected to high torque input, the rigidity of the arc spring is low, which can easily cause it to break due to excessive contact and may generate collision loads.
Method used
In the vibration damping device, by setting a spring seat and a stop, the disc spring part and the stop part abut against each other before the arc spring is tightly pressed together, which restricts the movement of the spring seat, alleviates stress, and inhibits tight contact through sliding resistance.
Benefits of technology
It effectively suppresses the tightness of the arc spring when high torque is input, avoids spring breakage, does not affect the vibration damping performance, and does not increase the number of parts.

Abstract
The utility model provides a vehicle shock absorber device capable of inhibiting load generation caused by close contact of an arc spring during large torque input. The shock absorber device (20) comprises a seat (SS) that supports both ends of a spring (52 (52a, 52b)) and is provided with a disc spring portion (t) having spring characteristics, and a stop portion (Sa, Sb) provided on a flywheel main body (50a) that restricts movement of the seat (SS) by abutting against the disc spring portion (t) before the spring (52) is in close contact. Thus, before the spring (52) is in close contact, the disc spring portion (t) abuts against the stop portion (Sa, Sb), so that a restriction force generated by the abutment acts on the seat (SS), thereby relieving stress on the spring (52). Furthermore, the sliding resistance after the disc spring portion (t) abuts against the stop portion (Sa, Sb) also plays a role in stress relief. Therefore, load generation caused by close contact of the spring (52) during large torque input can be inhibited.
