Bean Cars was a brand of motor vehicles made in England by A Harper Sons & Bean, Ltd at factories in Dudley, Worcestershire, and Coseley, Staffordshire. The company began making cars in 1919 and diversified into light commercial vehicles in 1924.
1931–33 New model 20 hp (known as "23.8") introduced with 80 mm bore and 7 main bearings rated at 23.8 hp. 1933–34 New model Speed 20 consisting of 20.9 hp engine resurrected with improved exhaust manifold and downdraught carb installed in new cruciform braced chassis. 1933 18.2 hp engine installed in Speed 20 chassis and renamed 'Twenty'.
Founded in 1884 as the Bean Spray Pump Company in Los Gatos, California [1] by orchardist John Bean. [2] The company's first product was a piston pump, which Bean invented the pump to spray insecticide on the many fruit orchards in the area. A Bean sprayer is on display at the Forbes Mill museum there. [3]
The frequency and magnitude of this ride disturbance usually increases with speed, and vehicle suspensions may become excited when the rotating frequency of the wheel equals the resonant frequency of the suspension. Tire balance is measured in factories and repair shops by two methods: with static balancers and with dynamic balancers.
This engine was the first to locate one balance shaft higher than the other, to counteract the second order rolling couple (i.e. about the crankshaft axis) due to the torque exerted by the inertia caused by increases and decreases in engine speed. [6] [7] In a flat-four engine, the forces are cancelled out by the pistons moving in opposite ...
Sunbeam Cycles made by John Marston Limited of Wolverhampton was a British brand of bicycles [1] and, from 1912 to 1956 motorcycles. On John Marston's death after the First World War it was bought by Nobel Industries, Nobel became ICI. Associated Motor Cycles bought it in 1937; then, BSA bought Sunbeam in 1943.
Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
It came back on a twist-beam later for small-engine equipped variants of the Mk6 and Mk7 Golf. General Motors in Europe ( Vauxhall and Opel ) continued to use twist- or torsion-beam suspension up to the end of GM's ownership of the brand, and it was used on the 1982–1988 Cadillac Cimarron , Oldsmobile Firenza , and Buick Skyhawk .
