Curb feeler. Curb feelers or curb finders are springs or wires installed on a vehicle that act as "whiskers" to alert drivers when they are at the right distance from the curb while parking. The devices are fitted low on the body, close to the wheels. As the vehicle approaches the curb, the protruding feelers scrape against the curb, making a ...
BBS produces wheels for motorsport, OEM, and aftermarket applications. The company is often credited as pioneering the three-piece wheel and advancing the aluminum wheel industry over many decades, and remains one of the largest producers of automobile wheels in the world. [1] It is a part of KW Automotive since 2021.
Rail squeal is a screeching train-track friction sound, commonly occurring on sharp curves. Squeal is caused by the flanges of the wheels scraping across the railhead.
A wheelset is a pair of railroad vehicle wheels mounted rigidly on an axle allowing both wheels to rotate together. Wheelsets are often mounted in a bogie ("truck" in North America) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle. Most modern freight cars and passenger cars have bogies each with two ...
Train wheel. Railroad car wheels are fixed rigidly to their axle, ensuring both wheels of the wheelset rotate at the same rate. A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks. The wheel acts as a rolling component, typically press fitted onto an axle and mounted directly on a railway carriage or ...
The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential. A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur. In 1971, Buick introduced MaxTrac, which used an early ...
The empirical formula for for cast iron mine car wheels on steel rails is: [19] where As an alternative to using one can use , which is a different rolling resistance coefficient or coefficient of rolling friction with dimension of length.
Car wheels with spikes on the wheel and hubcap Wheel spikes are pointy protrusions attached to the wheels or hubcaps of vehicles, most commonly cars and semi-trucks. Most wheel spikes sold are made out of plastic painted to mimic metal and are primarily novelty items. [1][2][3] The safety and legality of wheel spikes have often been questioned, and they may constitute a traffic violation in ...
