A headset installed in a frame structure of a vehicle, said frame structure comprising a head tube, a front fork having a top tube inserted through said head tube, and a handlebar stem fastened to a top end of said top tube of said front fork, said head tube having a top annular inside mounting groove in a top end thereof, the headset comprising:
- an annular top bearing mounted in the top annular inside mounting groove of said head tube and peripherally disposed in contact with an inside wall of said head tube, said top bearing having a tapered face disposed on the inside at a top side thereof;
- an annular top packing member sleeved onto said top tube of said front fork and having a split, a vertical wall portion disposed in contact with the periphery of the top tube of said front fork, a top coupling flange upwardly extended from a top side of said vertical wall portion, a horizontal stop flange extended around a middle part of the periphery of said vertical wall portion, and a hooked retaining portion protruded from a bottom side of said vertical wall portion and hooked on a bottom edge of said top bearing, said horizontal stop flange having a tapered face fitting over the tapered face of said top bearing;
- and
- an annular top cap sleeved onto said top tube of said front fork and covered on said top bearing and said top packing member at a top side and stopped at a bottom side of said handlebar stem, said top cap having an inside annular mounting groove forced into engagement with the top coupling flange of said top packing member.
A headset installed in a frame structure of a vehicle, said frame structure comprising a head tube, a front fork having a top tube inserted through said head tube, and a handlebar stem fastened to a top end of said top tube of said front fork, the headset comprising:
- an annular top cup having a receiving open chamber;
- an annular top bearing mounted in the receiving open chamber of said top cup and peripherally disposed in contact with an inside wall of said top cup, said top bearing having a tapered face disposed on the inside at a top side thereof;
- an annular top packing member sleeved onto said top tube of said front fork, said top packing member comprising a split, a vertical wall portion disposed in contact with the periphery of the top tube of said front fork, a top coupling flange upwardly extended from a top side of said vertical wall portion, a horizontal stop flange extended around a middle part of the periphery of said vertical wall portion, and a hooked retaining portion protruded from a bottom side of said vertical wall portion and hooked on a bottom edge of said top bearing, said horizontal stop flange having a tapered face fitting over the tapered face of said top bearing;
- and
- an annular top cap sleeved onto said top tube of said front fork and covered on said top bearing and said top packing member at a top side and stopped at a bottom side of said handlebar stem, said top cap having an inside annular mounting groove forced into engagement with the top coupling flange of said top packing member.
A headset comprising:
- an annular top bearing having a tapered face disposed in a top side thereof on the inside;
- an annular top packing member having a split, a vertical wall portion, a top coupling flange upwardly extended from a top side of said vertical wall portion, a horizontal stop flange extended around a middle part of the periphery of said vertical wall portion, and a hooked retaining portion protruded from a bottom side of said vertical wall portion and hooked on a bottom edge of said top bearing, said horizontal stop flange having a tapered face fitting over the tapered face of said top bearing;
- and
