A traveling vehicle includes: a vehicle body frame, a pair of right and left front crawler traveling devices, a pair of right and left rear crawler traveling devices, a front suspension device that suspends the pair of right and left front crawler traveling devices on the vehicle body frame, and a rear suspension device that suspends the pair of right and left rear crawler traveling devices on the vehicle body frame. The front suspension device integrally suspends the pair of right and left front crawler traveling devices on the vehicle body frame and allows the pair of right and left front crawler traveling devices to be swingable in the vertical direction with respect to the vehicle body frame.

A bicycle may include a front triangle and a rear suspension system that couples the front triangle to a rear wheel and is dampened by at least one shock absorber. The rear suspension system includes a six-bar linkage having two ternary links separated from each other by one or more binary links, such that the two ternary links do not share a common joint. One of the ternary links may comprise a chain stay. In some examples, the other ternary link may comprise the front triangle. In some examples, the other ternary link may comprise a rocker arm coupling a seat stay link to the shock absorber.

The present invention is aimed at solving the problems of current bicycle suspension linkages. In particular, it is meant to balance the tradeoff between absorbing impact force, maintaining constant handling characteristics, and efficiently transmitting motive force. The present invention includes an optimal rear axle motion path, and a dual link suspension linkage to accomplish this goal.

A tiltable vehicle (100) is described comprising a vehicle frame (102, 108), one front wheel (124), two rear wheels (112A, 112B) and two swing arms. The swing arms are pivotably coupled to a pivot point (121) on the vehicle frame at a first end, and to one of the rear wheels at an opposing end. A swing arm (41) is rotatable around a rotational axis (42) lying in a plane of symmetry of the vehicle frame (102, 108). Each of two linkages (63, 64) is coupled at a first end to one of the swing arms at the pivot point. The vehicle comprises two connection arms (53, 56) arranged between the linkages (63, 64) and one outer end of the rocker arm (40). The connection arms comprise resilient members (61, 62) comprising a number of Belleville springs arranged in at least two groups of rings so as to create a non-linear spring characteristic.
