Service (motor Vehicle)
A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel. A tune-up should not be confused with engine tuning, which is the modifying of an engine to perform ''better'' than the original specification, rather than using maintenance to keep the engine running as it should. Common tasks involved in maintaining a vehicle * Inspection - vehicle components are visually inspected for wear or any leaks. A diagnostic is performed to identify any electrical components reporting a failure or a part operating outside of normal conditions. * Replacement - Given certain lubricants break down over time due to heat and wear, manufacturers recommend replacement. Any parts that are close to their expected fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maintenance (technical)
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure and supporting utilities in industrial, business, and residential installations. Terms such as "predictive" or "planned" maintenance describe various cost-effective practices aimed at keeping equipment operational; these activities occur either before or after a potential failure. Definitions Maintenance functions can be defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions: Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain ...

Drum Brake
A drum brake is a brake that uses friction caused by a set of Brake shoe, shoes or Brake pad, pads that press outward against a rotating bowl-shaped part called a brake drum. The term ''drum brake'' usually means a brake in which shoes press on the Brake lining, inner surface of the drum. When shoes press on the outside of the drum, it is usually called a ''Railway brake, clasp brake''. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a ''pinch drum brake'', though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. History The modern automobile drum brake was first used in a car made by Wilhelm Maybach, Maybach in 1900, although the principle was only later patented in 1902 by Louis Renault (industrialist), Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative material dissipated heat more effectivel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bus Garage
A bus garage, also known as a bus depot, bus base or bus barn, is a facility where buses are stored and maintained. In many conurbations, bus garages are on the site of former car barns or tram sheds, where trams (streetcars) were stored, and the operation transferred to buses. In other areas, garages were built to replace horsebus yards or on virgin sites when populations were not as high as now. Description Most bus garages will contain the following elements: *Internal parking *External parking *Fueling point *Fuel storage tanks *Engineering section *Inspection pits *Bus wash *Brake test lane *Staff canteen/break room *Administration office Smaller garages may contain the minimum engineering facilities, restricted to light servicing capabilities only. Garages may also contain recovery vehicles, often converted buses, although their incidence has declined with the use of contractors to recover break-downs, and the increase in reliability. Overnight, the more valuable or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auto Mechanic
An auto mechanic is a mechanic who services and repairs automobiles, sometimes specializing in one or more List of car brands, automobile brands or sometimes working with any brand. In fixing cars, their main role is to Diagnosis, diagnose and repair the problem accuratelSeasoned auto repair shops start with a (Digital) Inspection to determine the vehicle conditions, independent of the customers concern. Based on the concern, the inspection results and preventative maintenance needs, the mechanic/technician returns the findings to the service advisor who then gets approval for any or all of the proposed work. The approved work will be assigned to the mechanic on a work order. Their work may involve the repair of a specific part or the replacement of one or more parts as assemblies. Basic Service (motor vehicle), vehicle maintenance is a fundamental part of a mechanic's work in modern industrialized countries, while in others they are only consulted when a vehicle is already show ...

Automotive Battery
An automotive battery, or car battery, is a usually 12 Volt lead-acid rechargeable battery that is used to start a motor vehicle, and to power lights, screen wiper etc. while the engine is off. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car's electrical systems is still supplied by the battery, with the alternator charging the battery as demands increase or decrease. Battery in modern cars Gasoline and diesel engine Typically, starting uses less than three percent of the battery capacity. For this reason, automotive batteries are designed to deliver maximum current for a short period of time. They are sometimes referred to as "SLI batteries" for this reason, for starting, lighting and ignition. SLI batteries are not designed for deep discharging, and a full discharge can reduce the ...

Gearbox
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (who founded Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam-powered devices. Applications of these devices included pumps, mills and hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations. Automobiles Since the torque and power output of an internal combustion engine (ICE) varies with its rpm, automobiles powered by ICEs require multiple ...

Clutch
A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission. By disengaging the clutch, the engine speed (RPM) is no longer determined by the speed of the driven wheels. Another example of clutch usage is in electric drills. The clutch's input shaft is driven by a motor and the output shaft is connected to the drill bit (via several intermediate components). The clutch allows the drill bit to either spin at the same speed as the motor (clutch engaged), spin at a lower speed than the motor (clutch slipping) or remain stationary while the motor is spinning (clutch disengaged). Types Dry clutch A ''dry clutch'' uses dry friction to transfer power from the input shaft to the output shaft, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tires
A tire (North American English) or tyre (Commonwealth English) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, tires wer ...

Timing Chain
In a piston engine, either a timing belt (also called a ''cambelt'') or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's poppet valve, valves open and close at the correct times in relation to the position of the pistons. Design In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or gears), which in turn actuates the intake and exhaust poppet valve, valves. These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of gears. The teeth of the belt/chain/gears mesh with both the crankshaft and camshaft(s), thereby synchronising their motion. In many older overhead valve engines, the camshaft is located in the blo ...
