Rolls-Royce Silver Spirit
The Rolls-Royce Silver Spirit is a full-size luxury car produced by Rolls-Royce Motors, in Crewe, England, from 1980 to 1997. It was the first model in the SZ series. The Silver Spur is a long-wheelbase version of the Silver Spirit, produced from 1980 to 2000. It was the first car to feature a retractable '' Spirit of Ecstasy'': the spring-loaded mascot sank into the radiator shell if dislodged from its position. Mark I The Silver Spirit was introduced by Rolls-Royce in 1980 as the first of a new generation of company models. It formed the basis for the Flying Spur, Silver Dawn, Touring Limousine, Park Ward, and Bentley Mulsanne/ Eight series. The Spirit/Spur carried over the basic design of the Silver Shadow, its 6.75 L '' L410'' V8 engine and GM-sourced THM400 3-speed automatic gearbox, and unitary bodywork manufactured at Pressed Steel, which followed the styling of the Pininfarina designed Camargue. The Spur/Spirit continued the Silver Shadow's emphasis on ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rolls-Royce Motors
Rolls-Royce Motors was a British luxury car manufacturer, created in 1973 during the de-merger of the Rolls-Royce automotive business from the nationalised Rolls-Royce Limited. It produced luxury cars under the Rolls-Royce and Bentley brands. Vickers acquired the company in 1980 and sold it to Volkswagen in 1998. Bentley Motors is the company's direct successor; however, BMW acquired the rights to the Rolls-Royce trademark for use on automobiles and launched a new Rolls-Royce company shortly afterwards. History The original Rolls-Royce Limited had been nationalised in 1971 due to the financial collapse of the company, caused in part by the development of the RB211 jet engine. In 1973, the British government sold the Rolls-Royce car business to allow nationalised parent Rolls-Royce (1971) Limited to concentrate on jet engine manufacture. In 1980, Rolls-Royce Motors was acquired by Vickers. A marketing survey in 1987 showed that only Coca-Cola was a more widely known br ...

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 mass ...

Automatic Ride Control
An active suspension is a type of Suspension (vehicle), automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large spring (device), springs to maintain static support and dampen the vertical wheel movements caused by the road surface. Active suspensions are divided into two classes: true active suspensions, and adaptive or semi-active suspensions. While adaptive suspensions only vary shock absorber firmness to match changing road or dynamic conditions, active suspensions use some type of actuator to raise and lower the chassis independently at each wheel. These technologies allow car manufacturers to achieve a greater degree of ride quality and car handling by keeping the chassis parallel to the road when turning corners, preventing unwanted contacts between the vehicle frame and the ground (especiall ...

Frankfurt Motor Show
The International Motor Show Germany or International Mobility Show Germany, in German known as the ''Internationale Automobil-Ausstellung'' (''IAA'' – International Automobile Exhibition), is one of the world's largest mobility trade fairs. It consists of two separate fairs, that subdivided in 1991. While the ''IAA Mobility'' displays passenger vehicles, motorcycles and bikes, the ''IAA Transportation'' specializes in commercial vehicles. Before the separation, the show was held solely at the Messe Frankfurt. In 2021, the IAA adopted the ''New Mobility World'' concept, formats and business model, rebranded to IAA Mobility, and moved to Munich. The IAA is organized by the Verband der Automobilindustrie (VDA – Association of the German Automotive Industry) and is scheduled by the Organisation Internationale des Constructeurs d'Automobiles (OICA), who recognize the IAA as one of the "big five" most prestigious auto shows worldwide.

Shock Absorber
A shock absorber or damper is a mechanical or hydraulics, hydraulic device designed to absorb and Damping ratio, damp shock (mechanics), shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically thermal energy, heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in Pneumatic cylinder, air cylinders, the hot air is usually exhausted to the atmosphere. In other types of ...

Ride Height
Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point of the automobile, typically the bottom exterior of the differential housing (even though the lower shock mounting point may be lower); or, more properly, to the shortest distance between a flat, level surface, and the lowest part of a vehicle other than those parts designed to contact the ground (such as tires, tracks, skis, etc.). Ground clearance is measured with standard vehicle equipment, and for cars, is usually given with no cargo or passengers. Function Ground clearance is a critical factor in several important characteristics of a vehicle. For all vehicles, especially cars, variations in clearance represent a trade-off between handling, ride quality, and practicality. A higher ride height and ground clearance means that the wheels have more vertical room to travel and absorb road shocks. Also, the car is more capable of being driven on surfaces that ...

Self-levelling Suspension
Self-levelling refers to an automobile suspension system that maintains a constant ride height of the vehicle above the road, regardless of load. Purpose Many vehicle systems on a conventional vehicle are negatively affected by the change in attitude coming from changes in load - specifically a heavy load in the rear seat or luggage compartment. This change in attitude affects aerodynamic properties, headlight aim, braking, bumpers, shock absorption from the suspension and the vehicle's performance in a collision. Most of the braking power is on the front wheels of a vehicle, which means you will have more effective braking when more weight is over the front wheels. When the rear end has a heavy load, the braking is not as effective. The weight is concentrated on the rear end of the vehicle, and the rear brakes need to do all of the work. When braking quickly in this situation, the front brakes will be easier to lock up because of the lack of weight transfer to the front of th ...

Hydropneumatic
Hydropneumatic devices (or hydro-pneumatic devices) are systems that operate using water and gas. The devices are used in various applications. Description A hydropneumatic device is a tool that functions by using water and gas. ''Hydropneumatic'' refers to the pneumatic (gas) and hydraulic (water) components needed for operation of the devices. Hydropneumatic accumulators or pulsation dampeners are devices which prevent, but do not absorb, alleviate, arrest, attenuate, or suppress a shock that already exists, meaning that these devices prevent the creation of a shock wave at an otherwise earlier stage. These can include pulsation dampeners, hydropneumatic accumulators, water hammer preventers, water hammer arrestors, and other things. Devices Hydropneumatic suspension Hydropneumatic lock Hydropneumatic recoil mechanism Hydropneumatic water hammer preventers Hydropneumatic water hammer preventers are chambers of sufficient volume to allow an extension of time i ...

Ride Quality
Ride quality refers to a vehicle's effectiveness in insulating the occupants from undulations in the road surface such as bumps or corrugations. A vehicle with good ride quality provides comfort for the driver and the passengers. Importance Good ride quality provides comfort for the people inside the car, minimises damage to cargo and can reduce driver fatigue on long journeys in uncomfortable vehicles, and also because road disruption can impact the driver's ability to control the vehicle. Suspension design is often a compromise between ride quality and car handling because cars with firm suspension can result in greater control of body movements and quicker reactions. Similarly, a lower center of gravity is more ideal for handling, but low ground clearance limits suspension travel and requires stiffer springs. Ambulances have a special need for a high level of ride quality to avoid further injury to the already-ill passengers. Technology Early vehicles, like the Ford Model ...

V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
