Abstract

The invention relates to a transmission (1; 1L, 1R) with a first power path (4) and a second power path (5; 5L, 5R) between an input path (2) and an output path (3; 3L, 3R), with a planetary gear set (10; 10L, 10R)), which comprises a first transmission element (11), a second transmission element (12), a third transmission element (13) and a fourth transmission element (14) from the group of planetary gear elements sun gear (S1, S2), planet carrier (C; C1, C2) and ring gear (R; R1, R2), wherein the first power path (4) can be connected to the first transmission element (11) via a first shift clutch (K1; K1L, K1R) and to the fourth transmission element (14) via a third shift clutch (K3; K3L, K3R), wherein the fourth transmission element (14) can be engaged by means of a first brake (B1; B1L, B1R) is able to be held in place, the second gear link (12) is connected to the output path (3; 3L, 3R), the third gear link is able to be held in place by means of a second brake (B2; B2L, B2R).In order to provide a gearbox (1; 1L, 1R) with four forward gears (F1, F2, F3, F4) and two reverse gears (R1, R2), especially for a tracked vehicle, which is optimized in terms of weight, small space requirement, material expenditure, cost and maintenance effort, the second power path (5) can be connected to the fourth gear element (14) of the planetary gear set (10; 10L, 10R) via a second shift clutch (K2; K2L, K2R).
