Abstract
A steering wheel damper for a vehicle, and a manufacturing method thereof, the method includes putting a plate which is directly fixed to a steering wheel and has a plurality of through holes and a mass member having a predetermined weight to reduce vibration and a central pin in a mold in order, injection-molding rubber, and molding a connection member for connecting the plate and the mass member and a cushion member for limiting movement of the mass member.
Claims4
A method for manufacturing a directly injection-molded steering wheel damper, which includes a lower mold on which a mass member is seated, a middle mold on which a plate is seated and which is spaced apart from the mass member at a predetermined interval, and an upper mold completely getting in contact in order to injection-mold a connection member and a cushion member, the method comprising the steps of:
- putting the mass member on a seating portion inside the lower mold;
- putting a middle molding portion, which touches an inclined surface of a fixing hole to mold a connection portion of the connection member, and the plate on the lower mold on which the mass member is put, and putting the plate and the middle mold, which has a separation portion to be spaced apart from the mass member at a predetermined interval;
- and
- closely putting the upper mold, which has an upper molding portion to mold the connection member and the cushion member, on the middle mold on which the plate is seated, and injection-molding rubber to make a damper having the connection member and the cushion member.
A steering wheel damper for a vehicle comprising:
- a plate directly mounted on a steering wheel,
- a mass member having a predetermined weight to attenuate vibration,
- a connection member coupled to the plate to be spaced apart from the mass member at a predetermined interval, and
- a cushion member coupled to the plate to limit the movement of the mass member in order to attenuate vibration generated and transmitted during traveling of the vehicle,
- wherein an upper end portion of the connection member is fixed while partially surrounding an extension portion and a body portion of the plate, and a lower end portion is fixed to a fixing hole of the mass member so that the damper is firmly combined without being separated.
