Steering apparatus for vehicle

摘要

A steering apparatus for a two-wheeled motor vehicle includes a handlebars-side steering shaft supported by a head pipe, a wheel supporting cylindrical shaft supported by a front axle and over which a hub is fitted, and a steering link mechanism. First and second link members of the link mechanism are connected to each other in a plurality of articulations such that the link members can angularly move. An amount of angular movement is limited to a predetermined range, and a distance between a front wheel-side end and the steering shaft-side end of the steering link mechanism can be changed. The front wheel-side end of the steering link mechanism is connected to the wheel supporting cylindrical shaft through a brake caliper bracket member.

1. A steering apparatus for a vehicle comprising:
a handlebar; an axle supporting arm vertically swingably supported by a vehicle body, the axle supporting arm extending forward from the vehicle body; a front axle fixed to a front end of the axle supporting arm; a wheel supporting cylindrical shaft laterally swingably supported by the front axle; a hub of a front wheel rotatably fitted on an outer periphery of the wheel supporting cylindrical shaft; a bracket member independent from the axle supporting arm, the bracket member extending radially outward of the front wheel from the wheel supporting cylindrical shaft; a steering shaft which is laterally turnably supported by a head pipe of a vehicle body frame; and a link mechanism which connects the steering shaft and the bracket member to each other such that a steering force can be transmitted from the handlebar to the front wheel, wherein the link mechanism includes a plurality of link members, the link members are connected to each other in a plurality of articulations such that the link members can angularly move around an angularly moving shaft which is parallel to a centerline of the wheel supporting cylindrical shaft, and the bracket member includes a portion which supports a brake caliper.
