ANEW four-speed commercialvehicle gearbox, with synchromesh mechanism incorporated in all forward gears, has been introduced by the automobile gearbox division of David Brown and Sons, (Huddersfield), Ltd., and is now in production.
Designated the David Brown S450 model, this gearbox was designed for passenger and goods-vehicle application. Prototypes were installed in the Seddon Pennine coach with underfloor engine. The box is now available for vehicles of 91-ton capacity (14 tons maximum loaded weight). Weighing 310 lb. including clutch housing, the S450 is capable of transmitting a maximum engine torque of 300 lb.-ft.
It can be supplied with clutch housing already fitted, or as an independent unit. A compact forward-control unit, with the control rod mounted on universal joints, allows for variations in layout and permits substantial tolerances in assembly. Primary, main and layshafts are mounted horizontally in an unusually shallow aluminium casing which gives maximum ground clearance without prejudice to a low, uninterrupted floor level.
