1931 Bugatti Type 51 cockpit, with Wilson preselector gearbox. The most common type of pre-selector gearbox was the Wilson, which used an epicyclic design. [5] [6] A precursor to the Wilson gearbox was the manually-controlled epicyclic gearbox used in the 1901–1904 Wilson-Pilcher cars built in the United Kingdom.
The gearbox of the car was also novel, having dual epicyclic gears and being bolted directly to the engine. This allowed four speeds, with direct drive in top gear. All the gears were helical, and enclosed in an oil bath, making for very silent transmission. Reverse gear was built into the rear axle, as was the foot-operated brake drum, all of ...
Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel. [ 4 ] [ 5 ] Typically, the planet gears are mounted on a movable arm or carrier , which itself may rotate relative to the sun gear.
The gearbox was housed in an aluminium casing and bolted directly onto the engine. It contained a main cone clutch and two epicyclic gears, allowing four forward speeds. All gears are helical which substantially reduces gear noise, and the drive is direct through in top gear.
Self-Changing Gears was a British company, set up and owned equally by Walter Gordon Wilson and John Davenport Siddeley, to develop and exploit the Wilson or pre-selector gearbox. Self-Changing Gears designed, built and licensed transmissions for various applications including light and heavy road vehicles, military, marine, and rail vehicles ...
Wilson epicyclic steering The British Mark V tank [ a ] was an upgraded version of the Mark IV tank . The tank was improved in several aspects over the Mark IV, chiefly the new steering system, transmission and 150 bhp engine, but it fell short in other areas, particularly its insufficient ventilation leading to carbon monoxide poisoning for ...
In 1918, some work went on to test a Lanchester epicyclic gearbox as the main transmission. The use of an epicyclic gearbox wasn't new, as Lanchester had used a manually-controlled a 3-speed since 1900. 1928, Wilson uses his knowledge of epicyclic gearboxes controlled by brake bands to produce his pre-selector gearbox.
The combined power of the engines went through a six-speed Wilson epicyclic gearbox, operated by compressed air. [8] The tank's suspension system was that which had been developed by Vickers for their Medium C prototype in the mid-1920s [19] The tank was carried by five double wheels bogies on each side. Four of the bogies were on bellcranks in ...
