Variable ratio transmission to drive a generator by a diesel engine

摘要

A variable-ratio transmission to drive a generator by a diesel engine. This transmission has a variable speed epicyclic gear, having a transmission path with a constant transmission ratio (10, 38, 12) and a transmission path with a variable transmission ratio (32, 30, 26, 28), an epicyclic gear (14) being provided to combine or split the powers of the said transmission paths. In this case, the variable- speed epicyclic gear, as a transmission path with a variable transmission ratio, has a hydrostatic drive with two pump-motor units (32, 26). At least one pressure reservoir (44, 46, 60, 68) for hydraulic fluid can be connected or disconnected between the pump- motor units (32, 26).
