Abstract
A transmission system, for example for a vehicle. The transmission system includes an input shaft (3); first and second lay shafts (4,6); an output shaft (1); first and second torque paths (A'-C',B'-D') for transferring drive between the input shaft (3) and the first lay shaft (4), third and fourth torque paths (A'-E,B'-F') for transferring drive between the input shaft (3) and the second lay shaft (6), fifth and sixth torque paths (G'-K',H'-L') for transferring drive between the first lay shaft (4) and the output shaft (1), and seventh and eighth torque paths (I' -K',3'-L') for transferring drive between the second lay shaft (6) and the output shaft (1). The torque transfer means includes selector means (29,33 1 a-d) arranged to selectively transfer drive along a selection of the first to eighth torque paths thereby transferring drive from the input shaft (3) to the output shaft (1), wherein the first and second lay shafts (4,6) are arranged substantially parallel to the input shaft (3) and the distance between the longitudinal axis of the input shaft (3) and the longitudinal axis of the first lay shaft (4) is different from the distance between the longitudinal axis of the input shaft (3) and the longitudinal axis o the second lay shaft (6).
