Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the m ...

Mercedes-Benz S-Class
The Mercedes-Benz S-Class, formerly known as ''Sonderklasse'' (German for "special class", abbreviated as "S-Klasse"), is a series of full-sized luxury sedans, limousines and armored sedans produced by the German automaker Mercedes-Benz, a division of the German company Mercedes-Benz. The S-Class is the designation for top-of-the-line Mercedes-Benz models and was officially introduced in 1972 with the W116, and has remained in use ever since. The S-Class is the flagship vehicle for Mercedes-Benz. The S-Class has debuted many of the company's latest innovations, including drivetrain technologies, interior features, and safety systems (such as the first seatbelt pretensioners). The S-Class has ranked as the world's best-selling luxury sedan. In automotive terms, ''Sonderklasse'' refers to "a specially outfitted car." Although used colloquially for decades, following its official application in 1972, six generations of officially named ''S-Klasse'' sedans have been produced. I ...

Jeep Wrangler
The Jeep Wrangler is a series of compact and mid-size four-wheel drive off-road SUVs manufactured by Jeep since 1986 and is currently in its fourth generation. The Wrangler JL, the most recent generation, was revealed in late 2017 and is produced at Jeep's Toledo Complex. The Wrangler is a direct progression from the World War II Jeep, through the CJ (Civilian Jeeps) produced by Willys, Kaiser-Jeep, and American Motors Corporation (AMC) from the mid-1940s through the 1980s. Although neither AMC nor Chrysler (after it purchases AMC in 1987) have claimed that the Wrangler was a direct descendant of the original military model — both the CJ Jeeps and the conceptually consistent Wrangler, with their solid axles and open top, have been called the Jeep model as central to Jeep's brand identity as the rear-engine 911 is to Porsche. Similar to the Willys MB and the CJ Jeeps before it, all Wrangler models continue to use a separate body and frame, rigid live axles both front an ...

VW Tiguan
The Volkswagen Tiguan () is a car produced by German manufacturer Volkswagen since 2007, sitting between the smaller T-Roc and the larger Touareg in the company's crossover SUV range. The first generation is based on the PQ46 platform, while the second generation, released in 2016, utilizes the Volkswagen Group MQB A2 platform. It is generally considered to be a medium-sized SUV in Europe, while in North America it is considered to be a compact crossover. The name ''Tiguan'' is a portmanteau of the German words ''Tiger'' ("tiger") and ''Leguan'' ("iguana") and won a naming contest by German car magazine publisher ''Auto Bild''—from a field of names that also included ''Namib'', ''Rockton'', ''Samun'' and ''Nanuk''. As of the spring of 2020, six million units had been sold worldwide, with 910,926 units manufactured in 2019 alone. This makes the Tiguan the best-selling car overall in the Volkswagen Group.

Honda Accord
The , also known as the in Japan and China for certain generations, is a series of cars manufactured by Honda since 1976, best known for its four-door sedan variant, which has been one of the best-selling cars in the United States since 1989. The Accord nameplate has been applied to a variety of vehicles worldwide, including coupes, station wagons, hatchbacks and a Honda Crosstour crossover. Since its initiation, Honda has offered several different car body styles and versions of the Accord, and often vehicles marketed under the Accord nameplate concurrently in different regions differ quite substantially. It debuted in 1976, as a compact hatchback, though this style only lasted through 1989, as the lineup was expanded to include a sedan, coupe, and wagon. By the sixth-generation Accord at the end of the 1990s, it evolved into an intermediate vehicle, with one basic platform but with different bodies and proportions to increase its competitiveness against its rivals in diff ...

Rolls-Royce Phantom (2003)
The Rolls-Royce Phantom is a full-sized luxury saloon car made by Rolls-Royce Motor Cars. Launched in 2003, it was the first Rolls-Royce developed and introduced after BMW purchased the right to use the Rolls-Royce name and logo in 1998. It was the seventh Rolls-Royce design to use the Phantom nameplate. It is credited with successfully reviving the Rolls-Royce brand and restoring Rolls-Royce's reputation as a maker of luxury cars. The Phantom Drophead Coupé and Phantom Coupé are two-door derivatives of the Phantom launched in 2007 and 2008, respectively. From 2003 until the launch of the smaller Ghost in 2009, the Phantom was the only car produced by Rolls-Royce. The Phantom acted as the company's flagship model but was less exclusive than all previous Phantoms (none of which surpassed the 600 per year). Initial release (2003–2012) Construction The Phantom uses a unique chassis platform, body, interior, and retains traditional Rolls-Royce design cues. The body is ...

Bicycle And Motorcycle Geometry
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a bike handles. Wheelbase Wheelbase is the ''horizontal'' distance between the centers (or the ground contact points) of the front and rear wheels. Wheelbase is a function of rear frame length, steering axis angle, and fork offset. It is similar to the term wheelbase used for automobiles and trains. Wheelbase has a major influence on the longitudinal stability of a bike, along with the height of the center of mass of the combined bike and rider. Short bikes are much more suitable for performing wheelies and stoppies. Steering axis angle The steering axis angle is called caster angle when measured from vertical axis or head angle when measured from horizontal axis. The steering axis is the axis about which the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full-size Car
Full-size car—also known as large car—is a vehicle size class which originated in the United States and is used for cars larger than mid-size cars, it is the largest size class for cars. In Europe, it is known as E-segment or F-segment. After World War II, the majority of full-size cars have used the sedan and station wagon body styles, however in recent years most full-size cars have been sedans. The highest-selling full-size car nameplate is the Chevrolet Impala, sold as a full-size car from 1958 to 1986, 1994 to 1996, and from 2000 to 2020. Current definition The United States Environmental Protection Agency (EPA) ''Fuel Economy Regulations for 1977 and Later Model Year'' (dated July 1996) includes definitions for classes of automobiles. Based on the combined passenger and cargo volume, ''large cars'' (full-size cars) are defined as having an ''interior volume index'' of more than for sedan models, or for station wagons.

Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bike Dimensions
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedan (automobile)
A sedan or saloon (British English) is a passenger car in a three-box configuration with separate compartments for an engine, passengers, and cargo. The first recorded use of the word "sedan" in reference to an automobile body occurred in 1912. The name derives from the 17th-century litter known as a sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style include the close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan, and sedanet/sedanette. Definition A sedan () is a car with a closed body (i.e. a fixed metal roof) with the engine, passengers, and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles, but in practice, the typical characteristics of sedans are: * a B-pillar (between the front and rear windows) that supports the roof * two rows of seats * a three-box design with the engine at the front and the c ...
