<p>This invention relates to a kind of split-power final reduction gear comprises a final driving casing (1), two driving pinions (2) and (4), a pair of split-power cylindrical gears (3) and (5), heavy-duty differential assembly (6) and a driven gear (7). Input power applies to either driving pinion (2) or (4), then half of the input power is shifted to the other driving pinion through split-power cylindrical gears (3) and (5). The driven gear (7) is supported on the differential assembly (6), and same number of teeth are machined in both sides of it. The driven gear engages with both driving pinions, concentrates the power from two transmission branches to itself and in tern transfers the power to differential assembly. With present invention, hub reductors can be eliminated while ground clearance were kept unreduced, thus the cost of driving axles is cut down, fuel consumption and noise are decreased.</p> |
