Title: (EN) Fire truck with rear-mounted engine
Abstract: front page image
(EN)

A fire truck characterized by its reduced operating noise level and improved drive train includes a frame having front and rear regions. An occupant cab is mounted upon the frame front region, and the engine is located at the rear region having a transmission associated therewith. A gear box mounted upon the frame intermediate the front and rear regions includes a close coupled fire pump attached thereto and the gear box includes an input shaft directly connected to the engine transmission. An output shaft of the gear box is directly connected to the differential associated with the vehicle rear wheels, and shifting means within the gear box selectively connects the engine and transmission to the differential or the fire pump. The fire pump gear box eliminates an intermediary transfer case and provides significant cost and weight advantages as well as eliminating the need for special power transmitting components.
