Title:
HYSTERESIS MECHANISM FOR VEHICLE DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/119172
Kind Code:
A1
Abstract:
Provided is a hysteresis mechanism for a vehicle damper device which can achieve positive and negative variable hysteresis, said hysteresis mechanism having a structure capable of generating a targeted hysteresis torque. In a hysteresis mechanism (30), a control plate is formed from a first control plate (34) and a second control plate (38). A cone spring (36) is inserted between the first control plate (34) and the second control plate (38). As a result, the cone spring (36) does not come into direct contact with a friction member, and relative rotation of the spring and friction member as in conventional structures is eliminated. There is thus no need to pass the friction member through a disk plate and stop the rotation of the friction member. Accordingly, it is also not necessary to provide play when stopping the rotation of the friction member, so the targeted hysteresis torque can be generated.
