Semi-trailer aerodynamic devices are devices affixed to semi-trailers, for the purpose of reducing aerodynamic drag caused by air turbulence. The two major types of device in use are trailer skirts (or side skirts ), affixed to the underside of trailers, and trailer tails (or boat tails , or rear fairings ), affixed to the rear.
Steering system showing drag link. A drag link converts rotary motion from a crank arm, to a second bellcrank, usually in an automotive steering system.. While the origin of the term is not clear, it pre-dates the automobile, and is described as in use in 1849 as a means of rotating a Ducie cultivator being operated by cable by stationary steam engine (or between engines).
The combination of a semi-trailer and a tractor truck is called a semi-trailer truck (also known simply as a "semi-trailer", "tractor trailer", or "semi" in the United States). [1] A large proportion of a semi-trailer's weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly, or the tail of another trailer ...
This can be to improve the drag coefficient of the vehicle's body at speed or generate downforce. In passenger vehicles, the focus shifts to directing the airflow into the engine bay for cooling purposes. Pickup truck bed spoiler: This attaches only to the top of the truck bed rails near the rear. Used with a bed cover, this spoiler is intended ...
Modern cars do not use pure Ackermann steering, partly because it ignores important dynamic and compliant effects, but the principle is sound for low-speed maneuvers. Some racing cars use reverse Ackermann geometry to compensate for the large difference in slip angle between the inner and outer front tires while cornering at high speed.
Pro FWD is a class in drag racing. The E.T. Bracket categories are no-electronics classes. The E.T. Bracket categories are no-electronics classes. Delay devices , throttle stops , air shifters , transbrakes , etc. or any device that transmits real-time, on-track data to the driver or any remote location are prohibited.
6-speed gear shifter in a 2015 Volkswagen Passat Estate. The shift pattern refers to the layout of the gears. In a typical manual transmission car, first gear is located to the left, and forwards. In many trucks and some sports cars it is instead in a "dog leg" position, to the left and rearwards.
