Portal axle gear for use in e.g. city bus, has driven toothed wheel arranged between planetary gears, and differential and crown wheel that are dimensioned based on gear transmission ratio that is adjusted based on toothed wheel diameter

摘要

The gear has a planetary gear set (1) with an internal gear (2), a sun gear (3) and planetary gears (4). The planetary gear set is actuated by an axial shaft (6) that is attached with a differential (5). A driven toothed wheel (7) is arranged between the gears (4). The differential (5) and a crown wheel are dimensioned small based on a gear transmission ratio, which is adjusted based on a diameter of the wheel (7).
