<p>A speed-variable-differential rear axle transmission mechanism belongs to three-wheel or four-wheel motor vehicle transmission device. The center shaft of the motor (1) rotor which is extended into the gear box (2) is connected with a centrifugal clutch center disk (3) and a centrifugal clutch outer disk (4). Centrifugal clutch swinging blocks (5) and springs are arranged on the centrifugal clutch center disk (3). An overrunning clutch (6) is arranged on a shaft sleeve of the centrifugal clutch outer disk (4). A notched belt (7) is jointed on outer side of the overrunning clutch (6) shaft sleeve. The other end of the notched belt (7) is jointed with a rear driven belt wheel (10) which is arranged on a main shaft extending from the gear head (14). The other side of the gear head (14) is connected with a rear axle (8), two ends of which are provided with braking blocks (15). And the other side of the rear driven belt wheel (10) is provided with a rear driven wheel shaft sleeve and a spring (12), a cover (13) and a differential box (9), which are cooperated with each other. The speed-variable-differential rear axle transmission mechanism has the advantages of simple, reasonable and compact structure.</p> |
