Combined bridging and splitting circuit for a gearbox has a drive element, rotational speed or torque conversion units, two power branches and switchable clutches

摘要

Combined bridging and splitting circuit (1) for a gearbox (30) has a drive element (36) and a torque conversion unit (37). The circuit has two inputs (9, 10) and at least a switchable clutch (16) with two clutch levels, at least a rotational speed / torque converter in each power branch (12, 13), a clutch between the input to the drive element and the combined bridging and splitting circuit and a clutch between the torque converter arrangement in each of the power branches and the input to the bridging and splitting circuit.
