Hubometer
A hubometer (from ''hub'', center of a wheel; ''-ometer'', measure of) or hubodometer, is a device mounted on the axle of any land vehicle to measure the distance traveled by a vehicle based on the rotations of the wheel hub. The whole device rotates with the wheel, except for an eccentrically mounted weight on an internal shaft. The weight remains pointing downwards, and drives the counting mechanism as the body of the hubometer rotates around it. Typical uses Hubometers are essential for semi-trailers, serving as the primary method to track the accumulated distance traveled throughout the vehicle's lifespan. They find application in buses, trucks, or trailers, particularly those whose tires are provided to the vehicle operator through an independent company under a "price per thousand kilometers" contract. In this arrangement, the tire company installs the hubometer to obtain accurate measurements of the distance covered. In New Zealand, hubodometers are used for the cal ...

Road User Charges (New Zealand)
Road user charges (RUC) are a tax paid by users of vehicles which use energy that is not taxed at its source (e.g., fuel tax). Taxed fuels Vehicles powered by petrol, compressed natural gas (CNG), and liquefied petroleum gas (LPG) generally do not pay RUC as these fuels are taxed at source. In New Zealand, other vehicles such as light diesel vehicles or trucks do pay RUC. Most large vehicles fall into this category. Taxed vehicles Vehicles required to pay RUC include: * Vehicles that have a manufacturer's gross laden weight of 3,500 kg (7,716 lb) or more * Vehicles that use diesel or other fuel not taxed at source Payment Charges are payable to the NZ Transport agency enforced by NZ police so all road users must ensure you have the correct documents displayed at all times in order to avoid a fine. There are several exemptions available for certain types of vehicles such as tractors however the vast majority of larger vehicles will be required to pay RUC. Details on paymen ...

Speedometer
A speedometer or speed meter is a gauge (instrument), gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. Other vehicles may use devices analogous to the speedometer with different means of sensing speed, eg. boats use a pit log, while aircraft use an airspeed indicator. Charles Babbage is credited with creating an early type of a speedometer, which was usually fitted to locomotives. The electric speedometer was invented by the Croats, Croat Josip Belušić in 1888 and was originally called a velocimeter. History The speedometer was originally patented by Josip Belušić (Giuseppe Bellussich) in 1888. He presented his invention at the Exposition Universelle (1889), 1889 Exposition Universelle in Paris. His invention had a pointer and a magnet, using eddy current, electricity to work. German inven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Technology
A vehicle () is a machine designed for self-propulsion, usually to transport people, cargo, or both. The term "vehicle" typically refers to land vehicles such as human-powered vehicles (e.g. bicycles, tricycles, velomobiles), animal-powered transports (e.g. horse-drawn carriages/wagons, ox carts, dog sleds), motor vehicles (e.g. motorcycles, cars, trucks, buses, mobility scooters) and railed vehicles (trains, trams and monorails), but more broadly also includes cable transport ( cable cars and elevators), watercraft (ships, boats and underwater vehicles), amphibious vehicles (e.g. screw-propelled vehicles, hovercraft, seaplanes), aircraft (airplanes, helicopters, gliders and aerostats) and space vehicles (spacecraft, spaceplanes and launch vehicles). This article primarily concerns the more ubiquitous land vehicles, which can be broadly classified by the type of contact interface with the ground: wheels, tracks, rails or skis, as well as the non-contact tec ...

Tach Timer
The tach(ometer) timer is an instrument used in aviation to accumulate the total number of revolutions performed by the engine. The unit of measure is equivalent to the number of hours of running at a certain, specific reference speed of rotation. If the reference speed of rotation is 2400 RPM then the timer runs in real time when the engine is running at 2400 RPM, half speed while the engine is run at 1200 RPM (a fast idle for some aviation engines) or at 5/6ths real time at 2000 RPM (a slow cruise speed). The tach timer integrates over time the instantaneous rotation speed displayed by the tachometer. The displayed number is incremented by one if the engine is run at its reference speed for one hour. The quantity recorded is referred to as tach(ometer) hours. If the reference rotation speed is 2400 RPM then the tach timer records :\frac Uses The tach timer is usually used to schedule engine maintenance, although it is just an approximation of "Time in service" which is use ...

Hobbs Meter
Hobbs meter is a generic trademark for devices used in aviation to measure the time that an aircraft is in use. The meters typically display hours and tenths of an hour, but there are several ways in which the meter may be activated: # It can measure the time that the electrical system is on. This maximizes the recorded time. # It can be activated by oil pressure running into a pressure switch, and therefore runs while the engine is running. Many rental aircraft use this method to remove the incentive to fly with the master electrical switch off. # It can be activated by another switch, either an airspeed sensing vane under a wing (as in the Cessna Caravan) or a pressure switch attached to the landing gear (as in many twin engine planes). In these cases, the meter only measures the time the aircraft is actually flying. Metrics such as Time In Service and Turbine Actual Runtime are kept to monitor overhaul cycles, and are usually used by commercial operators under Federal Aviation R ...

Taximeter
A taximeter or fare meter is a mechanical or electronic device installed in taxicabs and auto rickshaws that calculates passenger fares based on a combination of distance travelled and waiting time. Its shortened form, "taxi", is also a metonym for the hired cars that use them. History The modern taximeter was invented by Germany, German Friedrich Wilhelm Gustav Bruhn in 1891, and the List of Daimler cars, Daimler Victoria—the world's first meter-equipped (and gasoline-powered) taxicab—was built by Gottlieb Daimler in 1897. Taximeters were originally mechanical and mounted outside the cab, above the driver's side front wheel. Meters were soon relocated inside the taxi, and in the 1980s electronic meters were introduced. k constant Constant expressed in pulses per kilometre which represents the number of pulses the taximeter must receive in order to correctly indicate a distance traveled of one kilometre. Functioning Taximeters, when they are installed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachometer
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a axle, shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes . Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine revolutions and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two. History The first tachometer was described by Bryan Donkin in a paper to the Royal Society of Arts in 1810 for which he was awarded the Gold medal of the society. This consisted of a bowl of mercury constructed in such a way that centrifugal force caused the level in a central tube to fall when it rotated and brought down the level in a narrower t ...

Tachograph
A tachograph is a device fitted to a vehicle that automatically records its speed and distance, together with the driver's activity selected from a choice of modes. The drive mode is activated automatically when the vehicle is in motion, and modern tachograph heads usually default to the other work mode upon coming to rest. The rest and availability modes can be manually selected by the driver whilst stationary. A tachograph system comprises a sender unit mounted to the vehicle gearbox, the tachograph head and a recording medium. Tachograph heads are of either analogue or digital tachograph, digital types. All relevant vehicles manufactured in the European Union, EU since 1 May 2006 must be fitted with digital tachograph heads. The recording medium for analogue heads are wax coated paper discs, and for digital heads there are two recording mediums: internal memory (which can be read out with one of a variety of download devices into a so-called .ddd file) and digital driver ...

Odometer
An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical). The noun derives from ancient Greek , ''hodómetron'', from , ''hodós'' ("path" or "gateway") and , ''métron'' ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth of Nations, Commonwealth. History Classical Era Possibly the first evidence for the use of an odometer can be found in the works of the ancient Roman Pliny the Elder, Pliny (NH 6. 61-62) and the ancient Greek Strabo (11.8.9). Both authors list the distances of routes traveled by Alexander the Great (r. 336-323 BC) as by his bematists Diog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
