Renaissance Tropica
The Tropica or Tropica Roadster is an all-electric car made by Renaissance Cars in the 1990s. It was introduced for the model year 1995 and built in a limited number of units, but never entered series production due to financial issues. Overview Renaissance Cars was founded by Bob Beaumont, who previously founded the company which produced the Citicar in the 1970s. The company was headquartered in Palm Bay, Florida. The Tropica Roadster was designed by Jim Muir. Specifications The car was to use an ABS body on an aluminum backbone chassis. Although the first prototype had a fiberglass unibody, later vehicles used an aluminum chassis and a plastic body. The total weight was about at the prototype stage, with plans to reduce it by a further in the production version; the manufacturer ultimately specified the weight of the car as . The battery capacity was about 11.2 kWh, coming from twelve 6V lead-acid batteries, each with a capacity of 156 Ah; the batteries were removable ...

Rear-engine, Rear-wheel Drive Layout
In automotive design, an RR, or rear-engine, rear-wheel-drive layout places both the engine and drive wheels at the rear of the vehicle. In contrast to the RMR layout, the center of mass of the engine is between the rear axle and the rear bumper. Although very common in transit buses and coaches due to the elimination of the drive shaft with low-floor buses, this layout has become increasingly rare in passenger cars. Overview Most of the traits of the RR configuration are shared with the mid-engine rear-wheel-drive, or MR. Placing the engine near the driven rear wheels allows for a physically smaller, lighter, less complex, and more efficient drivetrain, since there is no need for a driveshaft, and the differential can be integrated with the transmission, commonly referred to as a transaxle. The front-engine front-wheel-drive layout also has this advantage. Since the engine is typically the heaviest component of the car, putting it near the rear axle usually results in more ...

Backbone Chassis
Backbone tube chassis is a type of automobile construction chassis that is similar to the body-on-frame design. Instead of a two-dimensional ladder-type structure, it consists of a strong tubular backbone (usually rectangular in cross section) that connects the front and rear suspension attachment areas. A body is then placed on this structure. It was first used in the English Rover 8hp of 1904 and then the French Simplicia automobile in 1909. The backbone chassis was extensively developed by Hans Ledwinka who used it in greater numbers on the Tatra 11 and subsequent vehicles. Ledwinka later used backbone frame with central tube and axles with swinging driveshafts on Tatra trucks, became known as ''Tatra-concept''. Design The truck backbone chassis is a design feature of Czech Tatra heavy trucks (cross-country, military etc.). Hans Ledwinka used this style of chassis for the Tatra 11 car in 1923. He then developed the design on trucks with 6x4 model Tatra 26, which had ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alameda, California
Alameda ( ; ; Spanish for "Avenue (landscape), tree-lined path") is a city in Alameda County, California, located in the East Bay (San Francisco Bay Area), East Bay region of the Bay Area. The city is primarily located on Alameda (island), Alameda Island, but also spans Bay Farm Island, Alameda, California, Bay Farm Island and Coast Guard Island, as well as a few other smaller islands in San Francisco Bay. The city's estimated population in 2019 was 77,624. History Spanish & Mexican era Alameda occupies what was originally a peninsula connected to Oakland. Much of it was low-lying and marshy. The higher ground nearby and adjacent parts of what is now downtown Oakland were the site of one of the largest coastal oak forests in the world. Spanish colonists called the area ''Encinal'', meaning "forest of evergreen oak". ''Alameda'' is Spanish for "grove of poplar trees" or "tree-lined avenue." It was chosen as the name of the city in 1853 by popular vote. The inhabitants at the ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novato, California
Novato (Spanish for "Novatus") is a city in Marin County, California, in the North Bay region of the Bay Area. At the 2020 census, Novato had a population of 53,225. History What is now Novato was originally the site of several Coast Miwok villages: Chokecherry, near downtown Novato; Puyuku, near Ignacio; and Olómpali, at the present-day Olompali State Historic Park. Mexican era In 1839, the Mexican government granted the Rancho Novato to Fernando Feliz. The rancho was named after a local Miwok leader who had probably been given the name of Saint Novatus at his baptism. Subsequently, four additional land grants were made in the area: Rancho Corte Madera de Novato, to John Martin in 1839; Rancho San Jose, to Ignacio Pacheco in 1840; Rancho Olómpali, awarded in 1843 to Camilo Ynitia, son of a Coast Miwok chief; and Rancho Nicasio, by far the largest at , awarded to Pablo de la Guerra and John B.R. Cooper in 1844. Post-Conquest era Following the American Conquest of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...

Car And Driver
''Car and Driver'' (''CD'' or ''C/D'') is an American automotive enthusiast magazine. In 2006 its total circulation was 1.23 million. It is owned by Hearst Magazines, who purchased prior owner Hachette Filipacchi Media U.S. in 2011. It was founded as ''Sports Cars Illustrated.'' The magazine is based in Ann Arbor, Michigan. History ''Car and Driver'' was founded as ''Sports Cars Illustrated'' in 1955. In its early years, the magazine focused primarily on small, imported sports cars. In 1961, editor Karl Ludvigsen renamed the magazine ''Car and Driver'' to show a more general automotive focus. ''Car and Driver'' once featured Bruce McCall, Jean Shepherd, and Brock Yates as columnists, and P. J. O'Rourke as a frequent contributor. Former editors include William Jeanes and David E. Davis, Jr., the latter of whom led some employees to defect in 1985 to create ''Automobile''. Rather than electing a Car of the Year, ''Car and Driver'' publishes its top ten picks each year ...

Fiberglass-reinforced Plastic
Fiberglass (American English) or fibreglass ( Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non- conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

DC Motor
A DC motor is any of a class of rotary electrical motors that converts direct current (DC) electrical energy into mechanical energy. The most common types rely on the forces produced by induced magnetic fields due to flowing current in the coil. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor, a lightweight brushed motor used for portable power tools and appliances can operate on direct current and alternating current. Larger DC motors are currently used in propulsion of electric vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrylonitrile Butadiene Styrene
Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)''x''·(C4H6)''y''·(C3H3N)''z'' is a common thermoplastic polymer. Its glass transition temperature is approximately . ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene crisscrossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The polybutadiene ...
