Abstract (en)
[origin: WO2020193423A1] The invention relates to a wheel head transmission (1) for a wheel head of a motor vehicle drive axle, in particular of 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 are connected to one another via a planetary transmission (PG). To now create a wheel head transmission (1) which is distinguished by a compact construction and a high transmission ratio, the planetary transmission (PG) is made up of a first planetary stage (P1) and a second planetary stage (P2), which respectively comprise in each case one first element (E11, E12), in each case one second element (E21, E22) and in each case one third element (E31, E32) in the form of in each case one sun gear (S01, S02), in each case one planet carrier (PS1, PS2) and in each case one ring gear (H01, H02). Here, the first element (E11) of the first planetary stage (P1) is connected to the first shaft (W1) for conjoint rotation, while the second element (E21) of the first planetary stage (P1) and the third element (E32) of the second planetary stage (P2) are connected to one another for conjoint rotation and are jointly connected to the second shaft (W2) for conjoint rotation. Furthermore, the third element (E31) of the first planetary stage (P1) and the first element (E12) of the second planetary stage (P2) are connected to one another for conjoint rotation, whereas the second element (E22) of the second planet stage (P2) is immobilized.
