Bicycle in which the frame includes a front triangle and a rear triangle suspended from said front triangle

摘要

The bicycle has a frame including a rear triangle (3) with upper and lower seat stays (10, 13) respectively articulated to upper and lower tie rods (11, 14) along two hinge axles (C, B). The upper rod is articulated to a front triangle (1) along a third hinge axle (D). The axles are located in a same plane when the bicycle is in static equilibrium position. The rear triangle is moved relative to the front triangle during shock damping, to induce misalignment of the rods. A bottom bracket (P) is associated to a third tie rod (15) articulated to the front triangle along a fourth hinge axle (A). The fourth hinge axle is positioned such that a horizontal force (F1) of cyclist on the bracket induces torque to pivot the upper and lower rods in a direction of realignment of the upper and lower rods.
