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.
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
The R uses an updated, fifth-generation Haldex 4MOTION four-wheel drive system. Under low loads or when coasting, the rear axle is decoupled, helping to reduce fuel consumption. Drive to the rear axle can be engaged in fractions of a second via the Haldex coupling, which is actuated by an electro-hydraulic pump.
Haldex AB (originally Halda Fickurfabrik AB, then Svenska AB Bromsregulatorer, SAB), also known as Haldex Group, is a Swedish company operating in the commercial vehicle industry. Haldex focuses on brake products, air suspension systems and products to enhance safety for heavy vehicles.
BMW xDrive is the marketing name for the all-wheel drive system found on various BMW models since 2003. [1] The system uses an electronically actuated clutch-pack differential to vary the torque between the front and rear axles. Models with the DPC torque vectoring system also have a planetary gearset to overdrive an axle or rear wheel as required.
Parts books were often issued as microfiche, though this has fallen out of favour. Now, many manufacturers offer this information digitally in an electronic parts catalogue. This can be locally installed software, or a centrally hosted web application. Usually, an electronic parts catalogue enables the user to virtually disassemble the product ...
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.
A pair of gladhand connectors between railroad cars A gladhand connector on a trailer. A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars.
