A road cleaning vehicle powertrain comprises a hydrostatic gearbox 34 having a casing 50 for directing power from a primary gearbox to a drivetrain and/or one or more road cleaning tools. The casing 50 comprises first and second sections 51, 52 and a plurality of passageways 106, 107 defined by the edges of both the first and second sections 51, 52. An input shaft is provided having an integral gear extending orthogonally therefrom and having an outer portion extending outside of the internal volume of the casing 50. The edges of the first and second sections 51, 52 preferably lie in the same plane as the shaft axes axis. The passageways 106, 107 may contain at least one bearing. The output shaft may also have an integral gear. The split casing 51, 52 allows the use of shafts with integral gears which allows the gearbox to transmit higher torques. |
