Embodiment Construction

[0016] figure 1 and 2 First, the transmission and differential 1 is shown schematically with a housing not shown in detail here.

[0017] The transmission and differential 1 has an input shaft 2 and two output shafts 3 and 4 arranged coaxially with respect to the input shaft 2 . The transmission and differential 1 has a transmission section and a differential section in the form of a spur gear differential 5 . The transmission section, not further shown here, has two planetary gear stages, input stage 6 and load stage 7 .

[0018] here in here figure 1 In the usual "half view" shown in , the transmission and the corresponding elements of the differential 1 can be seen very well. Thus, in figure 1 and 2 Only the "upper half" of the per se rotationally symmetrical arrangement, ie the important rotating components of the transmission and differential 1 , is shown schematically in FIG. The drive unit shown here (ie the transmission and differential 1 shown here) is used to ...

Abstract

The invention relates to a transmission and differential (1) with a housing, an input shaft (2) and two output shafts (3,4) arranged coaxially with respect to the input shaft (2), wherein a A transmission section and a differential section configured as a spur gear differential (5), wherein the transmission section has two planetary gear stages, namely an input stage (6) and a load stage (7), wherein the input stage The sun gear (12) of (6) is operatively connected to the input shaft (2), wherein the load stage (7) has a ring gear (13) fixed at the housing. The sun gear (14) of the load stage (7) is operatively connected to at least one planetary gear (16) of the input stage (6) via a bridge (15), and the at least one planetary gear (17) of the load stage (7) It can be operatively connected to the ring gear (19) of the input stage (6) via a bridge (18). This results in a compact design: one of the connections is designed as a switchable connection and the other as a fixed connection, that is, the input stage ( The ring gear (19) of 6) can be effectively coupled or disengaged from the bridge (18) of the load stage (7) (first alternative), or the sun gear (14) of the load stage (7) can be effectively The ground is connected to or disconnected from the bridge (15) of the input stage (6) (second alternative).

Description
