Centre Steer
The Centre Steer is the name given by enthusiasts to the prototype of the Land Rover 4x4 automobile. Being a prototype, only one example was built and the production vehicle differed significantly in many ways. Developed in late 1947 by the Rover Motor Co., the Land Rover was intended to be an agricultural vehicle inspired by the wartime Willys Jeep. Design and build Raw materials for car building were allocated by the government based on the company's export performance (as this earned much-needed trade revenue for post-war Britain). Because of this the Land Rover was designed from the outset to be exported to the British Empire and Commonwealth. Rover viewed this 4x4 as a stopgap to get production running and so the company could return to building luxury cars. The Land Rover had to be developed and produced with minimal outlay. The prototype was produced in September 1947. Its most distinctive feature was the centrally-mounted steering wheel, with passenger seats on eithe ...

V4 Engine
A V4 engine is a four-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The V4 engine is less common compared to straight-four engines. However, V4 engines have been used in automobiles, motorcycles, and other applications. Design Most V4 engines have two crankpins that are shared by opposing cylinders. The crankshaft is usually supported by three main bearings. Compared to the more common inline-four engine layout, a V4 engine is much shorter. Although different V angles can be used, if the two pistons are at a 90° V-angle with shared crankpins, the engine offers the additional advantage of perfect primary balance that reduces vibration. The design can also result in a smaller rocking couple than an inline-four engine, and the shorter crankshaft is less susceptible to the effects of torsional vibration due to its increased stiffness. Disadvantages of V4 engines include its design being inherently wider compared to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rover
Land Rover is a British brand of predominantly four-wheel drive, off-road capable vehicles, owned by multinational car manufacturer Jaguar Land Rover (JLR), since 2008 a subsidiary of India's Tata Motors. JLR currently builds Land Rovers in Brazil, China, India, Slovakia, and the United Kingdom. The Land Rover name was created in 1948 by the Rover Company for a utilitarian 4WD off-roader; yet today Land Rover vehicles comprise solely upmarket and luxury sport utility cars. Land Rover was granted a Royal Warrant by King George VI in 1951, and 50 years later, in 2001, it received a Queen's Award for Enterprise for outstanding contribution to international trade. Over time, Land Rover grew into its own brand (and for a while also a company), encompassing a consistently growing range of four-wheel drive, off-road capable models. Starting with the much more upmarket 1970 Range Rover, and subsequent introductions of the mid-range Discovery and entry-level Freelander line ( ...

Mockup
In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup may be a ''prototype'' if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: "You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer". Applications Mockups are used as design tools virtually everywhere a new product is designed. Mockups are used in the automotive device industry as part of the product development process, where dimensions, overall impression, and shapes are tested in a wind tunnel experiment. They can also be used to test consumer reaction. Systems engineering Mockups, wireframes and prototypes are not so clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rover Series
The Land Rover series I, II, and III (commonly referred to as ''series'' Land Rovers, to distinguish them from later models) are compact British off-road vehicles, produced by the Rover Company since 1948, and later by British Leyland. Though inspired by the World War II jeep, the Land Rover immediately distinguished itself from all other cars. From launch, it was the first mass-produced civilian four-wheel drive car with doors on it, and an available hard roof. Contrary to conventional car and truck chassis, it used a sturdier fully box-welded frame. Furthermore, due to post-war steel shortage, and aluminium surplus, Land Rovers received non-rusting aluminium alloy bodies, favouring their longevity. In 1992, Land Rover claimed that 70% of all the vehicles they had built were still in use. Most series models feature leaf-spring suspension with selectable two or four-wheel drive (4WD), however series I's produced between 1948 and mid-1951 had constant 4WD via a freewheel me ...

Rover P3
The Rover Sixty and Rover Seventy-Five or Rover P3 series were 1.6 and 2.0-litre executive cars announced in the middle of February 1948 and produced by the Rover Company until the summer of 1949. Two months after the announcement of the new cars "a new vehicle for agriculture" was announced, the Land Rover, with the engine of the new Sixty. Overview For the post-war market Rover had a new engine that had been in preparation since the late 1930s with overhead inlet and side exhaust valves. It was made in two versions for the car, the Rover 60 had a four-cylinder unit of 1595 cc and the Rover 75 had a six-cylinder version of 2103 cc. The gearbox and traditional Rover freewheel were kept unchanged from the previous model. To go with the engine a new car was prepared. Although the body was similar in styling to the Rover 12 and 16, many of the body panels were in fact new but the wings and bonnet from the 12 were carried over. The car was 0.5 inch (12 mm) wide ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the hydraulic automatic transmission (AT), and the continuously variable transmission (CVT), whereas the automated manual transmission (AMT) and dual-clutch transmis ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the ...

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 ...

Luxury Car
A luxury car is a car that provides increased levels of comfort, equipment, amenities, quality, performance, and associated status compared to moderately priced cars. The term is subjective and reflects both the qualities of the car and the brand image of its manufacturer. Luxury brands rank above ''premium brands'', though there is no fixed demarcation between the two. Traditionally, most luxury cars were large vehicles, though smaller sports-oriented models were always produced. "Compact" luxury vehicles such as hatchbacks, and off-road capable sport utility vehicles, are relatively modern trends. Classification standards Several car classification schemes include a luxury category, such as: * Australia: Since the year 2000, the Federal Government's luxury car tax applies to new vehicles over a certain purchase price, with higher thresholds applying for cars considered as fuel efficient. As of 2019, the thresholds were approximately AU$66,000 (US$,000) for normal car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Of Nations
The Commonwealth of Nations, simply referred to as the Commonwealth, is a political association of 56 member states, the vast majority of which are former territories of the British Empire. The chief institutions of the organisation are the Commonwealth Secretariat, which focuses on intergovernmental aspects, and the Commonwealth Foundation, which focuses on non-governmental relations amongst member states. Numerous organisations are associated with and operate within the Commonwealth. The Commonwealth dates back to the first half of the 20th century with the decolonisation of the British Empire through increased self-governance of its territories. It was originally created as the British Commonwealth of Nations through the Balfour Declaration at the 1926 Imperial Conference, and formalised by the United Kingdom through the Statute of Westminster in 1931. The current Commonwealth of Nations was formally constituted by the London Declaration in 1949, which modernised the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
