FRONT WHEEL SUPPORTING FRAME STRUCTURE OF SADDLE-RIDE VEHICLE

摘要

A cushion member is swingable with respect to a main frame about a fourth rotation axis to be expanded and compressed according to a movement of a front wheel. A first arm is swingable with respect to a front fork supporting member about a fifth rotation axis and with respect to the main frame about a sixth rotation axis. A second arm is swingable with respect to the front fork supporting member about a seventh rotation axis, with respect to the cushion member about an eighth rotation axis, and with respect to the main frame about a ninth rotation axis. The fourth to ninth rotation axes are substantially parallel to one another. The fourth rotation axis is provided to be substantially perpendicular to a plane including a second rotation axis about which the front fork is turnable.

1. A front wheel supporting frame structure of a saddle-ride vehicle, comprising:
a main frame which extends in vehicle front-rear directions; upper and lower arms which extend in the vehicle front-rear directions and by which a front wheel is supported to be swingable in up-down directions; and a cushion member which is expanded and compressed according to a movement of the front wheel to provide a cushioning effect, wherein an upper connection portion to which a rear end portion of the upper arm is swingably connected is formed in an upper front portion of the main frame, a lower connection portion to which a rear end portion of the lower arm is swingably connected is formed in a lower front portion of the main frame, a handle supporting portion by which a handle is supported to be turnable about a steering axis is formed to extend upward in the upper front portion of the main frame, behind the upper connection portion, an upper end portion of the cushion member is swingably connected to the handle supporting portion, and a lower end portion of the cushion member is swingably connected to the lower arm.
