All Sturmey-Archer gear hubs use epicyclic (planetary) geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple ...
Attached weights forced the blade back into the ground after the root was passed, allowing as much of the ground to be furrowed as possible. Although a little unorthodox, the plough in action appearing "like a ship in a storm", [12] it proved remarkably effective, and was dubbed the "stump-jump" plough (also spelt without the hyphen).

Specialized continue to produce the Stumpjumper, which, like mountain bikes in general, has evolved significantly since 1981 and seen iterations in full (front and rear) suspension and hardtail (front suspension only) options, with the former named the Stumpjumper FSR until the Stumpjumper line-up became full-suspension only.
Triumph TR5 Trophy with sprung hub. The Triumph sprung hub is a motorcycle suspension unit contained within a rear wheel hub. It was designed by Triumph engineer Edward Turner to give Triumph's existing rigid frames the option of rear suspension. It was one of the first motorcycle components to have a safety warning cast into its housing.
A hob, the cutter used for hobbing. Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets using a specialized milling machine.The teeth or splines of the gear are progressively cut into the material (such as a flat, cylindrical piece of metal or thermoset plastic) by a series of cuts made by a cutting tool.
The spline drive was part of the obsolete, U.S-designed Optimum Metric Fastener System and was defined by ASTM B18.2.7.1M, which was withdrawn in 2011, [83] making the spline drive obsolescent. Spline drives were specified for 5, 6.3, 8, 10, 12, 14, 16, and 20 mm size screws. [84]
A hub dynamo is a small electrical generator built into the front hub of a bicycle wheel that is usually used to power lights. Often the hub "dynamo" is not actually a dynamo, which creates DC, but a low-power magneto that creates AC. Most modern hub dynamos are regulated to 3 watts at 6 volts, although some will drive up to 6 watts at 12 volts.
A wheel hub motor, hub motor, or in-wheel motor is a motor that is incorporated into the hub of the wheel. Wheel-hub motors are commonly found on electric bicycles. Electric hub motors were well received in early electric cars, but have not been commercially successful in modern production cars [1] [2] because they negatively affect vehicle ...
