摘要:
The mechanism is comprised of a swivelling arm (1) hinged at one end to a wheel (2) and hinged at the other end to the frame of the vehicle, and is comprised of a power gear (20) and of a driven gear (21) in the axis of the driving wheel, both gears being associated by a chain. The mechanism is characterized in that the swivelling arm (1) is arranged parallel to the 'antisquat' direction defined by the distance between the axes (8, 10) of the wheels (2, 4) and the gravity center of the vehicle. The runs (28, 29) of the chain (22) are parallel to the swivelling arm (1). The effects of the driving wheel (2) and of the chain (22) on the swivelling arm (1), which tend to open and close said swivelling arm, are reduced.
摘要:
A rear wheel suspension mechanism for motorcycles and the like vehicles, of the kind used in motorcycles having a rear-wheel drive constituted of a sprocket (11) located at the output of the gearbox (13) and connected by a transmission roller chain (10) to a sprocket or gear wheel (9) integral with the driving rear wheel (8a), or connected to the said gear wheel through an intermediate gear, the ensemble of gearing and wheel being supported by an oscillating ensemble or unit. According to the invention, the mechanism comprises an oscillating support (1;101;215;314;410) articulated to the ends of at least two oscillating arms (4,4a; 201,202;301,302;401,402) placed longitudinally as regards the motorcycle traveling direction; an axle (8;108;218317; 411) for the rear driving wheel mounted in the oscillating support and having secured at one of their ends the sprocket or gear wheel (9;109;213;318;420) receiving the motion from the transmission roller chain (10;212;415); the opposite ends of the oscillating arms being articulated to respective points (5,6;105,106;203,204;404,405) of the motorcycle frame (205;305;406) placed above, under or coinciding with the center line (12;207;416) of the gearbox output sprocket. The arrangement is such that the oscillating arms constitute, together with the rear wheel axle oscillating support, an oscillating ensemble in the shape of at least an articulated polygon.
摘要:
Consists essentially in fitting the rear wheel (p) with possibility of relative swivelling on its vertical diametral axis, coupling it on a bracket (5,7) articulated on an axis parallel to the plane of the rear wheel (p), with movement governed from the steering column of the front fork of the vehicle and linked in turn by an articulated joint assembly to the end of the rear-wheel suspension system (15,16), on the bracket (5,7) of which is fitted the axle (4) of the vehicle's wheel (p) and the spindle (9) of the transmission sprocket, with multidirectional coupling between them. The stability in bends is improved.
摘要:
It comprises a plurality of compartments (3) separated by partition walls (2) provided with one-way valves (4). When the pneumatic tube receives a strong concentrated pressure, the air shifts within the tube through the valves (4), only in one sense. Thus the damping of the tyre rebound effect is achieved.
