Abstract
A pivot bearing arrangement, in particular a pivot bearing for a front wheel suspension system of a motorcycle, is provided that substantially reduces bearing breakaway torque, temperature sensitivity, complexity, space requirements and cost. The pivot bearing arrangement includes a first bearing part which enables a component to pivot about a first pivot axis, and a second bearing part which enables a component to pivot about a second pivot axis. The two bearing parts are connected to each other and form a structural unit.
Claims19
A pivot bearing for a front wheel suspension system of a motorcycle, comprising:
- a first bearing part configured to permit a first component supported thereon to pivot about a first pivot axis;
- and
- a second bearing part which permits a second component supported thereon to pivot about a second pivot axis,
- wherein
- the first and second pivot axes intersect,
- the second bearing part has an axial length centered on the first pivot axis, and
- the first and second bearing parts are coupled to form a structural unit.
A front wheel suspension system for a motorcycle, comprising:
- a wheel carrier;
- at least one of trailing and transverse links arranged to connect the wheel carrier to a supporting structure of the motorcycle;
- and
- at least one pivot bearing coupling the wheel carrier at least one of the at least one of trailing and transverse links,
- the at least one pivot bearing includes a first bearing part configured to permit a first component supported thereon to pivot about a first pivot axis and a second bearing part (38) which permits a second component supported thereon to pivot about a second pivot axis,
- the first and second pivot axes intersect,
- the second bearing part has an axial length centered on the first pivot axis, and
- the first and second bearing parts are coupled to form a structural unit.
A front wheel suspension system for a motorcycle, comprising:
- a wheel carrier in a form of a telescopic fork;
- and
- at least one pivot bearing coupling the wheel carrier to a supporting structure of the motorcycle,
- wherein
- the at least one pivot bearing includes a first bearing part configured to permit a first component supported thereon to pivot about a first pivot axis and a second bearing part (38) which permits a second component supported thereon to pivot about a second pivot axis,
- the first and second pivot axes intersect,
- the second bearing part has an axial length centered on the first pivot axis, and
- the first and second bearing parts are coupled to form a structural unit.
