Abstract:
A tricycle with independently-suspended rear wheels and having a rocking mechanism and a single shock absorber used to effect the damping action of both the left and the right suspension arms connected to the rear wheels. The left and right suspension arms are connected by a shock absorber and arcuate links and bell cranks provided at the opposite ends of the shock absorber. In response to upward and downward movement of the left and right suspension arms, the single shock absorber can be expanded and contracted to effect damping action of the left and right suspension arms. Accordingly, weight and cost can be reduced when compared with a conventional tricycle having two shock absorbers, one provided for each of the left and right suspension arms.

Abstract:
A shock absorber for mounting between a first frame member and a second frame member of a bicycle includes a first member adapted to couple to the first frame member and a second member disposed within the first member and adapted to couple to the second frame member. The first and second members rotate relative to each other, and an elastic member is disposed between the first member and the second member so that the elastic member expands and contracts in response to relative rotation of the first member and the second member. A linking mechanism couples the first member with the second member so that the first member and the second member are axially and radially immovable relative to each other.
Abstract:
A front wheel shock absorbing system for a bicycle wherein the legs of the front wheel fork include struts slidable in tubes. A cross brace bridges the front wheel and interconnects the struts to insure parallel movement of the struts. Elastomer pads between the tube ends and struts provide spring action. A cap in the tube ends provides access to the pads. A strut protruded from the cap down through a center bore in the pads maintains the pads in alignment. The strut end is flanged and removal of the cap, withdraws the strut and pads which are held onto the strut by the flange end. The flange is configured to permit the elastomer pads to be forced over the flange for replacement of the pads.
Abstract:
A front wheel shock absorbing system for a bicycle wherein the legs of the front wheel fork includes struts slidable in tubes. The struts are attached at one end to the wheel axle using a quick release clamping mechanism. Brackets on the strut ends are U shaped and simply drop over the axle and as a result of the clamping action are clamped onto the axle. To avoid upsetting of the parallel relation of the struts, one of the brackets is equipped with an axially slidable U shaped shoe. Thus, the clamping action merely moves the shoe of the one bracket closer to or farther from the other bracket but without affecting the spacing between the brackets and, thus, the struts. Fasteners fasten the shoe to the bracket following the clamping action.
Abstract:
A main frame includes a pair of left and right first frame pieces which extends rearwardly from above an engine, a pair of left and right second frame pieces each extending from a front portion in a direction slantwise downwardly and rearwardly of the associated first frame piece, and a pair of left and right third frame pieces each extending rearwardly from a lower end of the associated second frame piece through laterally of a cylinder block. The first mount section for supporting the front portion of the engine is constituted by a rubber mount in which a pair of left and right support portions, provided at respective joints between the second frame pieces and the third frame pieces, and a pair of first to-be-supported portions are connected together. The support portions are connected together through a connecting member that extends in a leftward and rightward direction.
