Title: TRANSMISSION FOR A TUNNEL BORING MACHINE WITH A PLANETARY STAGE WHICH IS SELECTIVELY ENGAGEABLE
Abstract:
The invention relates to a transmission having a first planetary stage (101), a second planetary stage (103), a first brake (149) and a second brake (151); wherein the first planetary stage (101) and the second planetary stage (103) in each case have a rotatably mounted internal gear (117, 119), a rotatably mounted planetary carrier (115, 125), one or more planetary gears (113, 127) which are mounted rotatably in the planetary carrier (115, 125), and a rotatably mounted sun gear (109, 121). The sun gear (109) of the first planetary stage (101) and the sun gear (121) of the second planetary stage (103) are connected for conjoint rotation; wherein the planetary carrier (115) of the first planetary stage (101) and the internal gear (119) of the second planetary stage (103) are connected for conjoint rotation; and wherein the first brake (149) acts on the internal gear (117) of the first planetary stage (101), and the second brake (151) acts on the internal gear (119) of the second planetary stage (103).
