초록 ▼

The rider powered vehicle has two steerable front wheels, each with a turning arm, and a single rear drive wheel. Power transmission means is provided between the rear wheel and a single push-pull and steerable handlebar mounted in a column assembly supported to oscillate about a lateral pivot axis. The handlebar is connected to a steering arm, and two steering links are connected at respective inboard and outboard pivotal connections between the steering arm and the two turning arms. Handlebar rotation causes the inboard pivotal connections to trace an arcuate path, and the lateral pivot axis is located to intersect the arcuate path generally at two spaced locations. This geometry provides a propulsion and steering mechanism that has substantially no interaction between the push-pull power strokes of the handlebar, for vehicular propulsion, and the handlebar rotation, for vehicular steering.

대표청구항 ▼

A vehicle comprising the combination of: a frame, two laterally spaced right and left front wheels and at least one rear wheel, means supporting the wheels to rotate relative to the frame about generally horizontal axes, and means supporting the front wheels to steer about generally vertical steering axes; a column and means supporting the column relative to the frame for oscillation about a laterally extended pivot axis, and means operatively coupling the column, at locations spaced from the pivot axis thereof, to the rear wheel, operable for powering the rear wheel upon column oscillation relative to the frame; and a steering member rotatably mounted within the column and presenting an arm, and elongated laterally extended rigid right and left links connected pivotally at inboard ends thereof to the steering member arm at locations having a radially spacing from the column and connected at outboard ends thereof to the respective right and left front wheels, operatively joining the front wheels to the steering member; the inboard link ends moving along an arcuate path concentrically of the column, upon steering member rotation in steering the vehicle; said arcuate path and said column pivot axis being located relative to one another to provide that said pivot axis generally intersects the arcuate path at two spaced intermediate axis-path intersections symmetrically disposed generally of a midpoint position of the steering member when oriented to provide for straight ahead vehicle movement.
