The second generation of Haldex coupling is an electronically controlled permanent 4x4 system with a Haldex differential calculating how much drive should be directed to the rear wheels. The Haldex system automatically distributes power between the front and rear wheels depending on slippage, but normally sends 95% of the power to the front wheels.
During 1999 Haldex delivered their first generation of disc brakes, called ModulX. A second generation, called ModulT, was launched in 2011 and ModulT is today the fastest growing product for Haldex. During the 1990s, Haldex bought the patent for creating the Haldex Coupling from the rally driver Sigvard “Sigge” Johansson and launched the ...
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
XWD, an acronym for Cross-Wheel Drive and also known as Haldex Generation 4, is an all-wheel drive system designed by Haldex in partnership with Saab. [1] The XWD is a permanent all-wheel drive system, that can pre-emptively and continuously change torque distribution before wheel slip occurs. Saab Turbo X, the launch vehicle for Saab XWD
Starting with the Mk4 generation A4-platform, the viscous coupling has been dropped in favour of a Haldex Traction electro-hydraulic limited-slip "coupler" (LSC) or clutch. The Haldex Traction LSC unit is not a differential and therefore cannot perform in the true sense like a differential. A Haldex Traction unit may divert up to a maximum 100% ...
The operation of this type is done, usually by the use of tools, at the coupler itself. The operator needs to leave the operator's station (usually the cab) to go to the end of the work equipment in order to effect the release of a bucket or attachment, and to do the same in order to attach the next bucket or attachment to be used. Semi-automatic
A Rzeppa-type CV joint. A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
