Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify '' current'' or '' voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large po ...

Tank Steering Systems
Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both. Half-track vehicles avoid this by combining steerable wheels and fixed-speed tracks. Early steering systems were adopted from tracked work vehicles, generally using a clutch to reduce power to one track, causing it to slow down. These designs have numerous problems, notably when climbing hills or running at high speed, as the reduction in power causes the overall speed to slow. Delivering power to both tracks while turning them at different speeds is a difficult design problem. A series of more advanced designs were introduced, especially through World War II, that maintained power to both tracks during steering, a concept known as regenerative steering. Some also allowed one track to move forward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Steering
Differential steering is the means of steering a land vehicle by applying more drive torque to one side of the vehicle than the other. Differential steering is the primary means of steering tracked vehicles, such as tanks and bulldozers, is also used in certain wheeled vehicles commonly known as skid-steer, and even implemented in some automobiles, where it is called torque vectoring, to augment steering by changing wheel direction relative to the vehicle. Differential steering is distinct from torque steer, which is usually considered a negative side effect of drive-train design choices. History A British agricultural company, Hornsby in Grantham, developed a continuous track, which was patented in 1905. The Hornsby tractors featured a track-steer clutch arrangement. Mechanisms There are several mechanisms that have been developed to vary the torque applied to different sides of a vehicle. These include ''clutch-brake'' steering, ''braked-differential'' steering, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat Tyre
A flat tire (British English: flat tyre) is a deflated pneumatic tyre, which can cause the rim of the wheel to ride on the tire tread or the ground potentially resulting in loss of control of the vehicle or irreparable damage to the tire. The most common cause of a flat tire is puncturing of the tire by a sharp object, such as a nail or pin, letting the air escape. Depending on the size of the puncture, the tire may deflate slowly or rapidly. Other causes Besides puncturing of the tire a flat can be caused by: failure of or damage to the valve stem; rubbing of the tire against the road, ripping the tire, or separation of tire and rim by collision with another object; excessive wear of the tire tread allowing explosive tire failure or allowing road debris to tear through it. Some tyres, particularly those with a slow leak, can be repaired and re-inflated; others, especially those with worn tread, must be replaced. Driving or riding with a flat tire Where a flat tire occurs, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter '' tau''. When being referred to as moment of force, it is commonly denoted by . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Control System
A traction control system (TCS), also known as ASR (from german: Antriebsschlupfregelung, lit=drive slippage regulation), is typically (but not necessarily) a secondary function of the electronic stability control (ESC) on production motor vehicles, designed to prevent loss of traction (i.e., wheelspin) of the driven road wheels. TCS is activated when throttle input and engine power and torque transfer are mismatched to the road surface conditions. The intervention consists of one or more of the following: *Brake force applied to one or more wheels *Reduction or suppression of spark sequence to one or more cylinders *Reduction of fuel supply to one or more cylinders *Closing the throttle, if the vehicle is fitted with drive by wire throttle *In turbocharged vehicles, a boost control solenoid is actuated to reduce boost and therefore engine power. Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylin ...

Individual Wheel Drive
Individual-wheel drive or IWD is a wheeled vehicle with a drivetrain that allows all wheels to receive torque from several motors independent of each other. The term was coined to identify those electric vehicles whereby each wheel is driven by its own individual electric motor. These vehicles inherently have a range of characteristics built-in that are more commonly attributed to four-wheel drive vehicles or vehicles with extensive control systems. These characteristics can be: * Four-wheel drive, i.e. the distribution of available power to all the wheels of a four-wheeled vehicle. * Anti-lock braking system * Anti-skid Other features * If one motor fails, the other motors are powerful enough to drive the vehicle to the nearest repair shop. * Low maintenance. * Easy replacement of motors. * No central gear box. * No mechanical differentials or lockers. * No long and heavy drive shafts. * On the spot, tank/wheelchair-like turning. * On the fly switching between FWD, RWD and A ...

Supercar
A supercar – also called exotic car – is a loosely defined description of street-legal, high-performance sports cars. Since the 2010s, the term hypercar has come into use for the highest performing supercars. Supercars commonly serve as the flagship model within a vehicle manufacturer's line-up of sports cars and typically feature various performance-related technology derived from motorsports. Some examples include the Ferrari 458 Italia, Lamborghini Aventador, and McLaren 720S. In the United States, muscle cars were often referred to as "supercars" during the 1960s. History Europe The Lamborghini Miura, produced from 1966–1973, is often said to be the first supercar. By the 1970s and 1980s the term was in regular use, if not precisely defined. One interpretation up until the 1990s was to use it for mid-engine two-seat cars with at least eight cylinders (but typically a V12 engine), a power output of at least and a top speed of at least .

Electric Vehicle
An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft. For road vehicles, together with other emerging automotive technologies such as autonomous driving, connected vehicles and shared mobility, EVs form a future mobility vision called Connected, Autonomous, Shared and Electric (CASE) Mobility. EVs first came into existence in the late 19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time.
