FRONT WHEEL SUSPENSION DEVICE, PARTICULARLY FOR THE SINGLE STEERING FRONT WHEEL OF A THREE-WHEELED VEHICLE, PARTICULARLY A STREET SWEEPER

摘要

P THIS SUSPENSION DEVICE INCLUDES LONG OSCILLATING ARMS 40 SUPPORTING WHEEL 76 AND WHICH OSCILLATE ON A FORK, AROUND A SUBSTANTIALLY HORIZONTAL AXIS, SPRINGS CONNECTING THEIR REAR ENDS TO THE FORK. THE ARMS 40 ARE RIGIDLY COUPLED (BAR 90) AT THEIR FRONT ENDS, SO THAT THEY CANNOT SWING INDEPENDENTLY FROM ONE ANOTHER. THIS BLOCKED ARM COUPLING MAINTAINS THE ROTATION PLAN OF THE PERPENDICULAR WHEEL AT THE HORIZONTAL AXLE OF THE FORK, WHICH REDUCES THE WEAR OF TIRES IN LOW-RANGE TURNS OR IN TRAFFIC ON UNEVEN TRUCKS. /P
