Beadlock
A beadlock or bead lock is a mechanical device that secures the bead of a tire to the wheel of a vehicle. Tires and wheels are designed so that when the tire is inflated, the tire pressure pushes the bead of the tire against the inside of the wheel rim so that the tire stays on the wheel and the two rotate together. In situations where tire pressure is insufficient to hold the bead of the tire in place, a beadlock is needed. There are several styles of beadlocks. For four-wheel drive vehicles, a ring with a number of bolts around the circumference can be used to clamp the tire to the wheel. For motorcycles, a rim lock or bead stopper is a curved plate tightened by a single bolt. For both four-wheel drive vehicles and motorcycles, a different style of beadlock can be used that is similar to an inner tube which is inflated to press the tire against the wheel. History Dodge Military trucks had the first beadlocks, called Combat Wheels; the 'combat wheels' were a divided-rim, that ...

Types Of Motorcycles
In the market, there is a wide variety of types of motorcycles, each with unique characteristics and features. Models vary according to the specific needs of each user, such as ''standard'', ''cruiser'', ''touring'', ''sports'', ''off-road'', ''dual-purpose'', ''scooters'', etc.Scooters are a type of motorcycle: * * * * * * Often, some hybrid types like ''sport touring'' are considered as an additional category. There is no universal system for classifying all types of motorcycles. However, some authors argue that there are generally six categories recognized by most motorcycle manufacturers and organizations, making clear distinctions between these six main types and other motorcycles. For example, scooters, mopeds, underbones, minibikes, pocket bikes, electric bikes such as surrons or talarias or even skark vargs, and three-wheeled motorcycles are often excluded from the main categories within these classifications, but other classification schemes may also include these ...

Rim (wheel)
The rim is the "outer edge of a wheel, holding the tire". It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as car, automobiles. For example, on a bicycle wheel the rim is a large hoop attached to the outer ends of the spokes of the wheel that holds the tire and tube. In cross-section, the rim is deep in the center and shallow at the outer edges, thus forming a "U" shape that supports the bead of the tire casing. In the 1st millennium BC, an iron rim was introduced around the wooden wheels of chariots to improve longevity on rough surfaces. Characteristics ;Design: The first pneumatic tires for bicycles were simple tubes in shape secured to the wooden outer concave surfaced circumference of the wheel by glue and air pressure pressing them against it. The surface for receiving the tube was not very secure thus causing the tires to sometimes come off the rims. Bicycle manufacturer and inventor Thomas B. Jeffery ...

Tire Tread
The tread of a tire or track refers to the rubber on its circumference that makes contact with the road or the ground. As tires are used, the tread is worn off, limiting its effectiveness in providing traction. A worn tire can often be retreaded. The word tread is often used casually to refer to the pattern of grooves molded into the rubber, but those grooves are correctly called the tread pattern, or simply the pattern. The grooves are not the tread, they are in the tread. This distinction is especially significant in the case of racing slicks, which have much tread but no grooves. Tires Street tires The grooves in the rubber are designed to allow water to be expelled from beneath the tire and prevent hydroplaning. The proportion of rubber to air space on the road surface directly affects its traction. Design of tire tread has an effect upon noise generated, especially at freeway speeds. Generally there is a tradeoff of tread friction capability; deeper pattern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automotive Accessories
The automotive aftermarket is the secondary parts market of the automotive industry, concerned with the manufacturing, remanufacturing, distribution, retailing, and installation of all vehicle parts, chemicals, equipment, and accessories, ''after'' the sale of the automobile by the original equipment manufacturer (OEM) to the consumer. The parts, accessories, etc. for sale may or may not be manufactured by the OEM. The aftermarket encompasses parts for replacement, collision, appearance, and performance. The aftermarket provides a wide variety of parts of varying qualities and prices for nearly all vehicle makes and models. Consumers have the option of repairing their vehicles themselves (the "do-it-yourself" or "DIY" segment) or can take the vehicle to a professional repair facility (the "do-it-for me" or "DIFM" segment). The aftermarket helps keep vehicles on the road by providing consumers the choice of where they want their vehicles serviced, maintained, or customized. Size ...

Tire Changer
A tire changer is a machine used to help tire technicians dismount and mount tires with automobile wheels. After the wheel and tire assembly are removed from the automobile, the tire changer has all the components necessary to remove and replace the tire from the wheel. Different tire changers allow technicians to replace tires on automobiles, motorcycles and heavy-duty trucks. New tire and wheel technology has improved certain tire changers to be able to change a low profile tire or a run-flat tire. Components Foot pedals The tire changer has two foot pedals. The left pedal is called the clamp control pedal, a three position pedal that opens and closes the rim clamps. Once pressed, pneumatic pistons move the 4 rim clamps together or apart simultaneously. The right pedal is the table top pedal, which is a three position pedal that controls the rotation of the table top. When the table top pedal is pressed down, the table top spins clockwise. The table top spins counter c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bead Breaker
A bead breaker is a tool used for separating tires from rims. The innermost diameter of the tire that interfaces with the rim of a wheel is called the tire bead. The bead is a thicker section of rubber, and is reinforced with braided steel cables, called the bead bundle. The surface of the bead creates a seal between the tire and rim on radial and bias-ply tires. Often, the bead can become stuck to the rim after rusting or corrosion occurs, requiring the use of a bead breaker in order to be removed. Usage Tire changers have a semi-automated bead loosening system for removing tires, but due to the high cost and lack of portability, these were not suitable in many cases. In addition, tire beads adhered to rims by heat or rust must often be broken free manually; in these cases, a bead breaker is ideal. Used like a chisel, a bead breaker leverages a mechanical advantage to drive the bead away from the rim. A need was experienced by 4x4 enthusiasts and overland travellers f ...

Threaded Fastener
A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel. Other methods of joining materials, some of which may create permanent joints, include: crimping, welding, soldering, brazing, taping, gluing, cement, or the use of other adhesives. Force may also be used, such as with magnets, vacuum (like suction cups), or even friction (like sticky pads). Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general-purpose fasteners. Furniture supplied in flat-pack form often uses cam dowels locked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Tyre
A motorcycle tyre (spelt tire in American English) is the outer part of motorcycle wheel, attached to the rim (wheel), rim, providing traction (engineering), traction, resisting wear, absorbing surface irregularities, and allowing the motorcycle to turn via countersteering. The two tyres' contact patches are the motorcycle's connection to the ground, and so are fundamental to the motorcycle's suspension (motorcycle), suspension behaviour, and critically affect Motorcycle safety, safety, Brake, braking, fuel economy in automobiles, fuel economy, Roadway noise, noise, and rider comfort. History The history of motorcycle tyres is a clear progression of steady improvement in grip, allowing better acceleration, braking, and turning, along with improved comfort, safety, durability, and reliability. This progression has generally meant a steady increase in tyre width, so much so that Kevin Cameron (journalist), Kevin Cameron noted the assumption among riders that "bigger must be better in ...

Street-legal Vehicle
Street-legal, road-legal, or road-going, refers to a vehicle such as a car, motorcycle, or light truck that is equipped and licensed for use on public roads, being therefore Roadworthiness, roadworthy. This will require specific configurations of lighting, signal lights, and safety equipment. Some specialty vehicles that will not be operated on roads, therefore, do not need all the features of a street-legal vehicle; examples are a vehicle used only off-road (such as a sandrail) that is Trailer (vehicle), trailered to its off-road operating area, and a Auto racing, racing car that is used only on closed race tracks and therefore does not need all the features of a street-legal vehicle. As well as motor vehicles, the street-legal distinction applies in some jurisdictions to track bicycles that lack street-legal brakes and lights. Street-legality rules can even affect racing helmets, which possess visual fields too narrow for use on an open road without the risk of missing a fast-mo ...

Polyester
Polyester is a category of polymers that contain one or two ester linkages in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include some naturally occurring chemicals, such as those found in plants and insects. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind, and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for their mechanical propert ...

Valve Stem
A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire), and is then automatically closed and kept sealed by the pressure in the chamber, or a spring (device), spring, or both, to prevent the gas from escaping. There are many types of valves, and they are most commonly used on Tire, automobile, Motorcycle tire, motorcycle, and bicycle tires, but also for many other applications. The most common type is the Schrader valve, but some road bicycles with skinny tires instead use the Presta valve. Schrader Schrader valves consist of a valve stem into which a poppet valve is threaded with a spring attached. They are used on virtually all automobile and motorbike tires and on wider-rimmed bicycle tires. In addition to tires, Schrader valves of varying diameters are used in refrigeration and Air conditioning, air conditioning systems, plumbing, Fuel injection, engine fuel injection, Car suspension, suspension systems, and SCUBA Divin ...

Contact Patch
The contact patch is the portion of a vehicle's tire that is in actual contact with the road surface. It is commonly used in the discussion of pneumatic (i.e. pressurized) tires, where the term is used strictly to describe the portion of the tire's tread that touches the road surface. The term “footprint” is used almost synonymously. Solid wheels also exhibit a contact patch which is generally smaller than the pneumatic “footprint”. Contact patch size The contact patch is the only connection between the road and the vehicle. Pneumatic rubber tires The size and shape of the contact patch, as well as the pressure distribution within the contact patch, are important to the ride qualities and handling characteristics of a vehicle. Since the wear characteristics of tires is a highly competitive area between tire manufacturers, a lot of the research done concerning the contact patch is considered highly proprietary and, therefore, very little is published on the subject.
