So here it goes:
A flood of new models, BMW presented at the IAA in Spetember 1991 ... the technical highlights was most certainly the "all wheel drive" 525ix with you on the success of the E30 model - the 325iX - wanted to go back ...
The first SUV from BMW had already been established before the 2nd World War ... the net.art for the German Wehrmacht model ... the SUV rolled in 325 ... in 3225 copies from the book "Eisenach" ... 1937-1940 ...
As the modern wheel "325" was presented to the press in August 1985 ... BMW could thus vorrweisen considerable sales success ... also there was this in the E30 TOURING version ... from November 1982 to August inclusive In 1985 was 670,000 units of the E30 for sale ... with the 325i convertible and the 325i wheel had been able to make the model so attractive ... even more essential at this time was the all-share in the vehicle market only 2.9% ... Today (2013 ) against but very, very small ...
The all-wheel drive of the E34 525ix based "mechanical" in the meantime, proven concept, but was generally far better than Audi Quattro revised ... thanks to fine electronics and the inclusion of ride comfort to the already successful model sedans ...
The principle of the front axle was taken from the 3 Series ... via a toothed chain the front wheels were driven by a runner with a leading forward (rigid) Wave ... this resulted in the differential and drove about half waves ... the wheels on the rear wheels were (as usual) driven by a manual or automatic transmission, drive shaft, differential and drive shafts ...
The new improvements resulted in an electronically controlled locking differential ... in a newly designed front axle ... this is not only improved straight-line stability but in conjunction with the new 16 inch tires, a hitherto unknown comfort and sportiness at the wheel area was also ... with the enlargement of the wheels of an installation of the modified (larger) enables brake ... they had now 296 mm diameter at the front wheels ...
The integral in the transfer case and rear differential locks could operate continuously from 0 to 100 percent ... which resulted in a maximum driving stability in the push and pull operation corresponding to wheel slippage occurring further ... the best possible traction on difficult and different underground ... the Raddrehzahlausgleich was also excellent ... unfortunately the differential on the front wheels was not lockable ...
Other highlights of the BMW 5 Series E34 all-wheel concept was further that no distortion in the drivetrain occurred ... thus could easily be driven hairpin bends ... parking spaces could be overcome as with the burlap and rear-wheel drive ... when braking could thus also released on all four wheels distributed constant forces ... neither distributor nor Achsgetriebe beinfluĂten here the brake ...
The locks off only as needed to ... for "driving state" ... "directional stability" ... for traction provided here a technically perfect collaboration of ... "Sensors" ... "controller" and ... "hydraulics components, "... for the degree of lock required which, however, was at normal speeds equal to zero, a perfect Resulting system ...
The controller already processed coming from the ABS system signals ... did not need to be specially adapted for this purpose ... and thus gave the wheel speed signals and some of it with the ... "throttle position" ... "engine speed" ... and "brake" ... the amount of the required locking force until the full closure of 100% ... transfer case was electromagnetically locked ...
The current flows directly from the controller to the solenoid ... it pulls immediately the plates together ... it creates a frictional engagement between the drive shafts on both axles (front and rear) ...
The rear axle (differential) is electro-hydraulically locked due to the higher wheel torques ... the controller operates the valves in the hydraulic unit and regulates the pressure so the locking torque ... this moment arises ebenfals by a disk pack that of a hydraulic piston articles ... the required pressure of the hydraulic unit is powered by the tandem pump ... is flanging on the power steering pump ... also serves the leveling ...
If the locks come into operation, this means a warning light in the AI (instrument cluster) appears ... to trigger unintended barriers - eg .: due to sensor failure or electrical cable break - are stored in the diagnostic system parameters which not only detect but also prevent ...
As with the E30 325iX, the locking force is distributed by means of the central differential with a drive value of 36% to the front and 64% to the rear axle ... this distribution of the drive torque has been chosen so that at the front and at the rear axle, the traction and tensile force optimum can be available ... even WITHOUT engagement of the locking differentials, vehicle acceleration equal to the value of the physically possible ... depending on the coefficient of friction of the road ... in extreme cases, the blocking effect could take place up to 100% on an axis ...
Out of all the technical innovations and circumstances out, of course you tried the concept of "tail-driven" E34 Sedan maintain ... so until then to get the "esteemed" driving comfort and sports performance sedan ... thus had some at the front and rear axle GIRL changes are made ... And YES, it would be the iX community only conditionally ... at the latest when buying parts is a painfully aware of the ...
So the front axle had been revised for accommodating the locking differential and drive shafts ... also because of the influence on the steering had to be minimized as far ... so the steering BEFORE wandered transaxle and therefore before the wheel center ... also was replaced the "recirculating ball steering" with a "rack-and-pinion steering system" ... this is supported by a stable cross tube to the body ... the wishbones were mounted on the front axle hydraulically damping bearing ... so maximum comfort and cushioning has been reached. .. also Radvibrationen and wheel imbalance characteristics were isolated by ...
Overall, the front axle of the 525ix was designed so that the risks posed by the wheels driving forces were able to pass only minimal and hardly noticeable reactions on the steering ... the benefits of this Vorderachsänderung but related as such in most all-wheel drive vehicles, the brake discs in the rim well had to walk ... to also block the larger sized discs may Bremm, the wheels were now increased from 15 to 16 inches ... a lot of fun at today's (2013) Winter tires ... the jump in price from 15 to 16 inch dimensions is enormous ...
Overall, the structural measures respectively the modifications of the conventional way, driven E34 were extremely high ... because the caster angle and caster offset for the driven front axle were unusually large ... but they help to achieve an excellent straight-line stability and perfect steering return ... disadvantages do not occur so , since the drive torque to the front axle but is less well ... as in all other E34 5 Series wheel-drive model had a "positive Lenrollradius" and anti-dive on ...
For excellent maneuverability and the power-assisted steering with variable ratio contributed ... indirect translation to the steering center and direct expectant translation at becomes larger steering angle, resulting in a harmonious steering response with sufficient precision for "sporty driving" and with small steering angles when parking. ..
Otherwise corresponded to the wheel-drive E34 E34 weitgehenst the other models in the engine ... but this was ONLY available in the inline six-cylinder 2.5-liter four-valve engine version ... also you could order the iX as a touring version of the ... purchase price was expected to be higher, but the daurch associated winter performance should be the one ... but get over the somewhat higher vehicle weight and slightly worse acceleration and maximum speed values also ...
