The Leyland Royal Tiger PSU was an underfloor-engined bus and coach chassis manufactured by Leyland between 1950 and 1954. ==Description== The Leyland Royal Tiger was an underfloor-engined heavyweight single deck bus or coach chassis, and sold well in the United Kingdom and overseas from launch. "Overseas" versions differed greatly from home market models. Upon launch in 1950 this was the fourth new marque of post-war Leyland single deck bus chassis since 1945. It used the same units as the Leyland-MCW Olympic but with a substantial steel ladder-frame chassis generally straight in elevation but with an up-sweep over the rear axle, to which operators could fit a coach-built body of their choice with the passenger floor about above the road surface. The flexibly-mounted Leyland 0.600H horizontal engine was mounted in the middle of the chassis frame, driving back through a unit mounted single-plate clutch and four-speed gearbox with synchromesh on second, third, and top, or later only on third and top, to a spiral-bevel rear axle. Steering was unassisted Marles cam and double roller, all component assemblies (save for some special export orders) were built by Leyland and were proven, having been previously used in the Tiger PS2 and/or Olympic. The majority of Royal Tigers were built as chassis only, although some were bodied as integral buses by Leyland. The last Tigers were completed in 1956, by which time 6,500 had been built. In the home market it had been supplanted by the lighter Tiger Cub which was in series production by 1953 and rapidly overtook the Royal Tiger in popularity with British operators. Whilst export markets demanded even more ruggedness and power, so from 1954 the Worldmaster came on-stream to satisfy them. Most notably the Royal Tiger was also the first post-war Leyland bus to feature a pictorial badge: a die cast bright metal item with a plated finish featuring a central shield carrying a coloured image of a charging open-mouthed Tiger on a black ground, this surmounted by ‘LEYLAND’ in inset red lettering, with ‘ROYAL’ and ‘TIGER’ on the left and right wings coming from the shield. Later bus models including the Tiger Cub, Worldmaster, Atlantean, Leopard, Lion PSR1, Royal Tiger Cub, Panther and Panther Cub also featured this style of badge, some Leyland goods models also used the shield badge, including models with the LAD and early Ergomatic cabs and notably the sole Leyland/Thompson Brothers' Dromedary rear-engined fuel tanker. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leyland Royal Tiger PSU」の詳細全文を読む スポンサード リンク
