Battle experience showed that the service life of the original vertical volute spring suspension (VVSS) of the late model M4 was shortening due to the tank's increasing combat weight with larger guns and heavier armor. Beginning in mid-1944, M4A3 models of the Sherman adopted a newly developed Horizontal Volute Spring Suspension (HVSS). [5]
Suspension units and roadwheels remained the M3 vertical volute pattern, with the idler above the mounting bracket, rather than the M4 development with the idler moved behind the mounting bracket to give more room for suspension travel. The Ram had a distinctive turret with a bolted flat-faced mantlet and the UK 6-pounder gun, with the hull ...
The M4 high-speed tractor used M4 Sherman tracks, roadwheels, and drive sprocket. However, the suspension was of the HVSS type, first introduced on a light tank T6 project in 1938. One variant was designed to tow the 90 mm anti-aircraft gun , and another was for the 155 mm gun or 8-inch howitzer . [ 1 ]
The M36 tank destroyer, formally 90 mm Gun Motor Carriage, M36, was an American tank destroyer used during World War II.The M36 combined the hull of the M10 tank destroyer, which used the M4 Sherman's reliable chassis and drivetrain combined with sloped armor, and a new turret mounting the 90 mm gun M3.
It mounted the 3-inch (76.2 mm) gun M7 in a rotating turret on a modified M4 Sherman tank chassis. It was built in two variants. The M10 GMC used the M4A2 Sherman chassis and the M10A1 used the M4A3 chassis. Production of the two models ran from September 1942 to December 1943 and October 1942 to November 1943, respectively.
A single Sherman V, serial T-148350, was then converted in a similar fashion. This proved successful in terms of ride quality, but unreliable in testing. By this time the US Army was testing a huge variety of new suspension concepts, eventually choosing one of these for the late-war M4E8 models. The single Horstman Sherman ran 340 miles (550 km ...
Existing Shermans include an 'Easy Eight', with cast chassis (likely mid production M4A1), D82081 (T23) turret, 76mm gun (with muzzle brake), HVSS suspension, and sharp nosed differential cover. [8] The collection is expected to include all major Sherman variants and an M10 tank destroyer once restorations are complete.
The M32 tank recovery vehicle was an armored recovery vehicle based on the chassis of the M4 Sherman medium tank, adding an 18 ft (5.5 m) boom, an A-frame jib, and a 30-short-ton (27 t) winch. It was 19.3 ft (5.9 m) long, adding 18 ft (5.5 m) when the boom, which is used to lift damaged vehicles, was fully extended.
