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.
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 first version in 1998.
The second generation has improved quality interior with more safety features as standard. [15] The Freelander 2 features a modified version of the Terrain Response off-road driving system as fitted to the Discovery 3 and the Range Rover. The 4WD system was developed in conjunction with Haldex and was called Third generation coupling. Vehicles ...
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
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.
[citation needed] The ZF "sliding pins and cams" became available, [2] and one example was the Type B-70 used during the Second World War in the military VWs (Kübelwagen and Schwimmwagen), although technically this was not a limited-slip differential, but a system composed of two freewheels, which sent the whole of the engine power to the ...
The gear ratios are the standard export models, but the final drive is a 3.9:1 ratio. The rear LSD is a viscous coupling type. The steering rack has a ratio of 16.5:1. The 4 gear electronic automatic transmission (4EAT) WRXs have a Variable Torque Distribution AWD system instead of the conventional viscous coupling center differential.
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.
