Pre-selector Gearbox
A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940-1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox is that the gear shift lever allowed the driver to "pre-select" the next gear, usually with the transmission remaining in the current gear until the driver pressed the "gear change pedal" at the desired time. The design removed the need for the driver to master the timing of using a clutch pedal and shift lever in order to achieve a smooth shift in a non-synchromesh manual transmission. Most pre-selector transmissions avoid a driver-controlled clutch entirely. Some use one solely for starting from a standstill. Preselector gearboxes were most common prior to the widespread adoption of the automatic transmission, so they were considered in comparison to the " crash gearbox" type of manual transmission. Preselector gearboxes were often ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Self-Changing Gears
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 as well as motor racing cars. Ownership changes Following the death of Walter Wilson in 1957, his son A Gordon Wilson took over the running of the company until his retirement in 1965. The original company Improved Gears Ltd was incorporated on 28 December 1928, and this later became Self-Changing Gears (SCG). The company moved a number of times in the early years, and in 1938 settled in premises at Lythalls Lane, Coventry. During World War II, additional premises were used at Burbage, Leicestershire. In 1935, Siddeley sold his interests in Armstrong Siddeley (including Self-Changing Gears) to Hawker Aircraft forming Hawker Siddeley. In 195 ...

Humber Limited
Humber Limited was a British manufacturer of bicycles, motorcycles, and cars incorporated and listed on the stock exchange in 1887. It took the name "Humber & Co Limited" because of the high reputation of the products of one of the constituent businesses that had belonged to Thomas Humber. A financial reconstruction in 1899 transferred its business to Humber Limited. From an interest in motor vehicles beginning in 1896, the motor division became much more important than the cycle division and the cycle trade marks were sold to Raleigh in 1932. The motorcycles were withdrawn from sale during the depression of the 1930s. Humber is now a dormant marque for automobiles as well as cycles. Following their involvement in Humber through Hillman in 1928 the Rootes brothers acquired 60 per cent of Humber's ordinary capital, sufficient for a controlling interest. The two Rootes brothers joined the Humber board in 1932 and began to make Humber the holding company for vehicle manufactu ...

Electromagnetic Clutch
Electromagnetic clutches operate electrically but transmit torque mechanically. This is why they used to be referred to as electro-mechanical clutches. Over the years, EM became known as electromagnetic versus electro-mechanical, referring more about their actuation method versus physical operation. Since the clutches started becoming popular over 60 years ago, the variety of applications and clutch designs has increased dramatically, but the basic operation remains the same today. Single-face clutches make up approximately 90% of all electromagnetic clutch sales. Electromagnetic clutches are most suitable for remote operation since no mechanical linkages are required to control their engagement, providing fast, smooth operation. However, because the activation energy dissipates as heat in the electromagnetic actuator when the clutch is engaged, there is a risk of overheating. Consequently, the maximum operating temperature of the clutch is limited by the temperature rating of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
