Abstract
A transmission system including first and second shafts (4, 2; 104, 102), a plurality of gear trains arranged to transfer drive between the first and second shafts, an instantaneous selector mechanism (46; 146), and at least one non-instantaneous selector mechanism (40, 44; 140, 144, 153, 157), wherein the instantaneous selector mechanism (46; 146) and the or each non-instantaneous selector mechanism (40, 44; 140, 144, 153, 157) are arranged to create torque paths between the first and second shafts (4, 2; 104, 102) via the gear trains, wherein each gear train is selectable when one other gear train is transmitting torque.
Claims37
A transmission system including:
- first and second shafts;
- a plurality of gear trains arranged to transfer drive between the first and second shafts;
- an instantaneous selector mechanism;
- and
- at least one non-instantaneous selector mechanism, wherein the instantaneous selector mechanism and the or each non-instantaneous selector mechanism are arranged to create torque paths between the first and second shafts via the gear trains, wherein each gear train is selectable when another gear train is transmitting torque.
A transmission system including:
- a first shaft;
- a first body rotatably mounted on the first shaft;
- a first gear train having a first gear element arranged to be driven by the first body
- a second gear train having a second gear element arranged to be driven by the first body;
- an
- a first selector mechanism arranged to selectively lock the first body for rotation with the first shaft.
A method of transmitting drive between first and second shafts via a gear train, comprising, selecting the gear train with a non-instantaneous selector mechanism and subsequently selecting the gear train with an instantaneous selector mechanism.
