The friction drive transmission was similar in concept to a continuously variable transmission, and had five fixed indents on the shift lever, that corresponding to pre-set drive ratios. [2] The driven friction wheel was moved between the center and outer rim of the flywheel to effect a change in drive ratio; nearer the center was a 'lower ...
Ixion engine on a Komet motorised bicycle, ca. 1902. This system is used, for example, to drive the spools in some tape recorders.In a typical configuration, one of the cylinders is the axle of an electric motor, say 1 mm in diameter, while the other is a disk with a hard rubber rim, say 50 mm in diameter, yielding a 1:50 mechanical advantage.
The Kawasaki 440, also called the T/A 440, is a Japanese twin-cylinder, in-line, two-stroke engine that was designed for snowmobiles and produced by Kawasaki Heavy Industries until the early 1980s. [1] The engine was widely adapted for other purposes, including ultralight aircraft and Formula 500 automobile racing.
The 165 cc, air-cooled, flat twin two-stroke engine drove the right-hand rear wheel by chain, and a variable-speed friction drive transmission was used, giving two forwards speeds and reverse. A top speed of 30 mph was claimed. [2] A motorcycle using the same engine, also with friction drive, was also offered for £28 10 shillings.
Initially the engines were supplied separately but from 1952 Bridgestone produced a bicycle fitted with the engine, the BS21 Bambi. [4] The 26 cc engine was mounted above the rear wheel and was inverted. [5] The rear wheel was driven by a friction drive on the tyre. 38 cc BS-31 and 49 cc BS-41 were later added. [4]
Although some mopeds, such as the VéloSoleX, had friction drive to the front tire, a motorcycle engine normally drives the rear wheel, power being sent to the driven wheel by belt, chain or shaft. Historically, some 2,000 units of the Megola were produced between 1921 and 1925 with front wheel drive, [ 1 ] and the modern Rokon , an all terrain ...
The Can-Am motorcycle operation was outsourced to Armstrong-CCM Motorcycles in 1983, with production ending in 1987. Can-Am resumed motorcycle production with a series of on-road three-wheel motorcycles, starting with the Spyder, using Rotax engines. As of 2020, there are three models: the Ryker uses the 2-cylinder 600 ACE and 3-cylinder 900 ...
From 1903 to 1908 complete motorcycles were produced [8] from the development of the first overhead valve motorcycle engine to be produced in the UK. [9]After that the factory concentrated on supplying its engines to other manufacturers, including Brough Superior, [10] Triumph Motorcycles, [11] A. J. Stevens & Co. Ltd, Enfield Cycle Co, Hazlewoods Limited, Zenith Motorcycles, Grindlay Peerless ...
