  • Make way for the Marauder
    with an automatic transmission, though it targets drivingenthusiasts. The transmission is a four-speed with overdrive, and Mercury engineers also added ahigh-stall torque converter, limited-slip differential, and 3.55:1 rear-axle ratio to improveacceleration. Nevertheless, the Marauder won't give you
  • Ford Harley-Davidson F-150 SuperCrew
    transmission has a 3.73:1 axle ratio and a limited-slip differential. And the V8 engine's throaty rumble sounds great, thanks to a high-performance exhaust system with a dual inlet/dual outlet muffler with flashy "slash-cut " chrome tips. Between the torque and horsepower, there's no problem keeping up
  • Tribometer Lifetime Study of Wheel Bearings
    In automotive applications, bearings form an integral part of many subassemblies, e.g., axle, engine, gearbox, etc. and their accurate characteristion needs to take into account the final configuration of the bearing system. In the case of ball and tapered roller bearings, different types
  • 2003 Cadillac CTS
    . The manual-equipped model is said to accelerate 0 to 60 mph in less than 7 sec. The relatively low final gearing with the manual transmission is good for get-up-and-go, but perhaps a bit too low for comfortable highway cruising. A higher axle gear ratio or a six speed would help. GM says expect about
  • 2002 Ford Explorer XLT 434
    frame with an independent-rear suspension (IRS) rather than a solid axle. Rear half-shafts fit through portholes in the frame rails instead of underneath, dropping the vehicle nearly 7 in. and freeing up enough space for a third-row seat (a $670 option). The IRS soaks up bumps in the road, improving
  • 2002 Lincoln Blackwood
    to a four-speed automatic transmission with overdrive and a locking torque converter. A 3.73 final-drive ratio and built-in hitch contribute to the 8,700-lb tow rating. The Blackwood rides on an independent SLA front suspension with coil springs, acceleration-sensitive shock absorbers
  • SVT F-150 Lightning -- A pickup for speed demons
    for strength and a 9-in. traction-lock differential with a 3.73:1 gear ratio for surprising neck-snapping acceleration (kudos to the supercharger as well). However, while accelerating on to the highway, the supercharger hesitates before kicking in. But, once it does, the acceleration is amazing. Also, I
  • Shoulder-Fillet Stresses Finesse
    , 2005, ) discusses how to get the right margin of safety out of FEA. Take a look at any nearby shaft or axle and chances are you'll see a shoulder fillet. Although it's better than a sharp corner, the shoulder fillet still has a stress-concentration factor (K ) designers must take into account
