ZAP Xebra
The ZAP Xebra was an electric car launched in May 2006 in the United States market by ZAP corporation. It is classified legally as a three-wheel motorcycle in some jurisdictions, and is available in both sedan (model SD) and pickup (model PK) truck variants. It has seat belts. It does not have regenerative braking. The PK pickup has a dump bed, with fold-down sides and tailgate, that allows easy access to the batteries, controller, motor, and charger. The Xebra was phased out in 2009, and in 2013 the company was ordered to buy back all of the 2008 models that were sold and destroy them due to a failure to meet the braking requirements for a motorcycle. Characteristics The top speed of the Xebra is , with a range of about with the standard batteries, or with the optional extended range batteries. The sedan version can carry up to five people. The listed cargo weight capacity for both the SD sedan and the PK pickup is 1000 lb (460 kg), although PK owners have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced some 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Motorcycles And Scooters
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Power is supplied by a rechargeable battery which drives one or more electric motors. Electric scooters are distinguished from motorcycles by having a step-through frame, instead of being straddled. Electric bicycles are similar vehicles, distinguished by retaining the ability to be propelled by the rider pedalling in addition to battery propulsion. Electric scooters with the rider standing are known as e-scooters. History 1895 to 1950 The early history of electric motorcycles is somewhat unclear. On 19 September 1895, a patent application for an "electrical bicycle" was filed by Ogden Bolton Jr. of Canton Ohio. On 8 November of the same year, another patent application for an "electric bicycle" was filed by Hosea W. Libbey of Boston. At the Stanley Cycle Show in 1896 in London, England, bicycle manufacturer Humber exhibited an electric tandem bicycle. Powered by a bank of storage ...

The Press Democrat
''The Press Democrat'', with the largest circulation in California's North Bay, is a daily newspaper published in Santa Rosa, California. History The newspaper was founded in 1897 by Ernest L. Finley who merged his ''Evening Press'' and Thomas Thompson's ''Sonoma Democrat'' (originally created as a voice for the Democratic Party). Finley also bought the ''Santa Rosa Republican'' in 1927 and merged it with the ''Press Democrat'' in 1948. Ernest L. Finley, his wife Ruth, daughter Ruth, and son-in-law Evert Person owned and published the "PD" between 1897 and 1985. Evert and Ruth Finley Person sold the paper to The New York Times Company in 1985. The most popular feature in the newspaper for many years was Gaye LeBaron's community column, according to a readership survey. LeBaron produced more than 8,000 columns between 1961 and her semi-retirement in 2001, writing on human interest, cultural events, ethnic history and local politics. ''The Press Democrat'' is now owned by Sonom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Highway Traffic Safety Administration
The National Highway Traffic Safety Administration (NHTSA ) is an agency of the U.S. federal government, part of the Department of Transportation. It describes its mission as "Save lives, prevent injuries, reduce vehicle-related crashes" related to transportation safety in the United States. NHTSA is charged with writing and enforcing Federal Motor Vehicle Safety Standards as well as regulations for motor vehicle theft resistance and fuel economy, as part of the Corporate Average Fuel Economy (CAFE) system. FMVSS 209 was the first standard to become effective on March 1, 1967. NHTSA cannot licenses vehicle manufacturers and importers, allows or blocks the import of vehicles and safety-regulated vehicle parts, administers the vehicle identification number (VIN) system, develops the anthropomorphic dummies used in U.S. safety testing as well as the test protocols themselves, and provides vehicle insurance cost information. The agency has asserted preemptive regulatory authori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-lock Braking System
An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle. ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practiced by skillful drivers before ABS was widespread. ABS operates at a much faster rate and more effectively than most drivers could manage. Although ABS generally offers improved vehicle control and decreases stopping distances on dry and some slippery surfaces, on loose gravel or snow-covered surfaces ABS may significantly increase braking distance, while still improving steering control. Since ABS was introduced in production vehicles, such systems have become increasingly sophisticated and effective. Mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brake Assist
Brake assist (BA or BAS) or emergency brake assist (EBA) is a term for an automobile braking technology that increases braking pressure in an emergency. The first application was developed jointly by Daimler-Benz and TRW/ LucasVarity. Research conducted in 1992 at the Mercedes-Benz driving simulator in Berlin revealed that more than 90% of drivers fail to brake with enough force when faced with an emergency. By interpreting the speed and force with which the brake pedal is pushed, the system detects if the driver is trying to execute an emergency stop, and if the brake pedal is not fully applied, the system overrides and fully applies the brakes until the anti-lock braking system (ABS) takes over to stop the wheels locking up. This is a lower level of automation than advanced emergency braking which is a collision avoidance system, which may initiate braking on its own if the onboard computer detects an imminent collision. Overview Many drivers are not prepared for the relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Absorbed Glass Mat
A valve regulated lead–acid (VRLA) battery, commonly known as a sealed lead–acid (SLA) battery, is a type of lead–acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel; proportioning of the negative and positive plates so that oxygen recombination is facilitated within the Electrochemical cell, cell; and the presence of a relief valve that retains the battery contents independent of the position of the cells. There are two primary types of VRLA batteries, absorbent glass mat (AGM) and gel cell (gel battery). The lead–acid gel batteries contain a mixture of sulfuric acid and finely divided silica. This mixture forms a thick paste or gel, thereby giving the batteries the name - Gel Cell. Gel batteries can be made with either flat or tubular positive plates. AGM batteries feature fiberglass mesh or an ultra thin glass mat (called AGM separator) between the battery plates which serves to contai ...

Ampere Hour
An ampere hour or amp hour (symbol: A⋅h or A h; often simplified as Ah) is a unit of electric charge, having dimensions of electric current multiplied by time, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3,600 coulombs. The commonly seen milliampere hour (symbol: mA⋅h, mA h, simplified as mAh) is one-thousandth of an ampere hour (3.6 coulombs). Use The ampere hour is frequently used in measurements of electrochemical systems such as electroplating and for battery capacity where the commonly known nominal voltage is dropped. A ''milliampere second'' (mA⋅s) is a unit of measurement used in X-ray imaging, diagnostic imaging, and radiation therapy. It is equivalent to a ''millicoulomb''. This quantity is proportional to the total X-ray energy produced by a given X-ray tube operated at a particular voltage. The same total dose can be delivered in different time periods depending on the X-ray tube current. To help e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep-cycle
A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for Lead–acid battery, lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or 'cranking' automotive batteries designed to deliver only a small part of their capacity in a short, high-current burst for cranking the engine. For lead-acid deep-cycle batteries there is an inverse correlation between the depth of discharge (DOD) of the battery and the number of charge and discharge cycles it can perform; with an average "depth of discharge" of around 50% suggested as the best for storage vs cost. Newer technologies than the traditional lead-acid (such as lithium-ion batteries) are becoming commonplace in smaller sizes in uses such as smartphones and laptops. The new technologies are also beginning to become common in the same form factor as the automotive lead-acid batteries, although at a lar ...
