Wheel head gear for a wheel head of a motor vehicle drive axle and wheel head

摘要

The invention relates to a wheel head transmission (1) for a wheel head of a motor vehicle drive axle, in particular a drive axle of a construction machine, comprising a first shaft (W1) and a second shaft (W2) in the form of a drive shaft (AnW) and an output shaft (AbW), which via a planetary gear (PG) are interconnected. In order to create a wheel head gear (1), which is characterized by a compact design and a high gear ratio, the planetary gear (PG) consists of a first planetary stage (P1) and a second planetary stage (P2), each with a first Element (E11, E12), a second element (E21, E22) and a third element (E31, E32) each in the form of a sun gear (SO1, SO2), a planetary web (PS1, PS2) and a ring gear each ( HO1, HO2). The first element (E11) of the first planetary stage (P1) is non-rotatably connected to the first shaft (W1), while the second element (E21) of the first planetary stage (P1) and the third element (E32) of the second planetary stage (P2) are rotatably connected to each other and are rotatably connected to the second shaft (W2). Furthermore, the third element (E31) of the first planetary stage (P1) and the first element (E12) of the second planetary stage (P2) are non-rotatably connected to one another, whereas the second element (E22) of the second planetary stage (P2) is fixed.
