The Dana 44 rear axle first saw use in the 1940s and is still in use today. The Dana 44 has a GAWR up to 3,500 lb (1,600 kg) and is a semi-floating type, having one bearing on the end of the axle shaft which carries the weight of the vehicle on the axle and also allows axle rotation.
The pinion pairs only mesh for the part of their length between the two spur gears, and rotate in opposite directions. The remaining length of a given pinion meshes with the nearer spur gear on its axle. Each pinion connects the associated spur gear to the other spur gear (via the other pinion).
A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.

In many cases, such as remote controlled toys, the pinion is also the drive gear for a reduction in speed, since electric motors operate at higher speed and lower torque than desirable at the wheels. However the reverse is true in watches, where gear trains commence with a high-torque, low-speed spring and terminate in the fast-and-weak escapement.
The Santa Fe was the first company to have roller bearing trucks made by Timken under their passenger cars, much to the delight of their passengers, and the bottom line for the company. Timken commissioned the construction of a demonstration boxcar in 1943 that was first displayed at the 1948 Chicago Rail Fair. It was a rolling advertisement ...
Chicago Lawyers' Committee For Civil Rights Under Law v. Craigslist, 519 F.3d 666 (7th Cir. 2008), [1] is a Seventh Circuit decision affirming a lower court ruling that Section 230 of the Communications Decency Act (CDA) provides immunity to Internet service providers that "publish" classified ads that violate the Fair Housing Act (FHA).
"The Loop" refers to the rectangular routes of Chicago's elevated trains. However, after the impact motorman Stephan A. Martin continued to apply traction power. This resulted in the rear cars continuing to push forwards, pinning the front of the train against the waiting Ravenswood on the right-angle turn of the track.
