Ford Explorer Center Cap (1999 - 2001), shown mounted to a cast aluminum wheel. A center cap, or centercap is a decorative disk on an automobile wheel that covers a central portion of the wheel. Early center caps for automobiles were small and primarily served the purpose of keeping dirt away from the spindle nut and wheel bearings of vehicles. [1]
Display of 1920s automobile hubcaps and a removal tool. Hubcaps were first used on the Newton Reaction Carriage in 1680. [4] The first hubcaps were more commonly known as dust or grease caps. These caps are threaded onto the center hub on the wood, steel, or wire wheel. These were made from the beginning of car manufacturing to 1932.
A centerlock wheel is a type of automobile wheel in which the wheel is fastened to the axle using a single, central nut, instead of the more common ring of 4 or 5 lug nuts or bolts. It is mostly used in racing and high end sports cars.
The conical lug's taper is normally 60 degrees (although 45 degrees is common for wheels designed for racing applications), and is designed to help center the wheel accurately on the axle, and to reduce the tendency for the nut to loosen due to fretting induced precession, as the car is driven. One popular alternative to the conical lug seating ...
The hub is the center of the wheel, and typically houses a bearing, and is where the spokes meet. A hubless wheel (also known as a rim-rider or centerless wheel) is a type of wheel with no center hub. More specifically, the hub is actually almost as big as the wheel itself. The axle is hollow, following the wheel at very close tolerances.
In the center of the exterior end is a metal pin aligned with the long axis of the tube; the pin's end is approximately flush with the end of the valve body. All Schrader valves used on tires have threads and bodies of a single standard size at the exterior end, so caps and tools generally are universal for the valves on all common applications.
Hub-center steering systems use an arm, or arms, on bearings to allow upward wheel deflection, meaning that there is no stiction, even under braking. Braking forces can be redirected horizontally along these arms, or tie rods, away from the vertical suspension forces, and can even be put to good use to counteract weight transfer .
Hombres were equipped with the S-10's 15×7" steel wheels (with 8 directional vents); the Hombre wheels were painted black (the S-10, Sonoma, and Blazer/Jimmy wheels were painted silver) since a majority were equipped with wheel covers with the Isuzu logo. Hombres were also available with the S-10's aluminum wheels with Isuzu center caps.
