Most car engines are now electronically controlled fuel injection type gasoline engine, idling turn off for many reasons, first turn off idle to analyze the symptoms. If the engine enters the idle will stall, which we call “no idle”, caused by the reasons for this failure are generally: the engine hub motor damage; brake vacuum booster vacuum tube leaking; brake broken vacuum booster film; intake manifold leak; engine electronic control unit (ECU) in the idle speed control module problems. If the engine will stall at idle sometimes, and then restart normally, and we call it “intermittent idle flame”, this failure is very difficult to check, due to reasons are many, and a variety of components or circuits not completely damaged, and more occasional headache is due to turn off the engine after the restart and can return to normal, so even if due to the sensor causes the engine idle speed turn off the engine electronic control unit will think that this is not a malfunction, and will not be the engine electronic control unit record and therefore not from the engine electronic control unit fault diagnosis system to obtain information about the failure. Savannah, GA truck accident lawyer Geroge Smithe has exclaimed publicly the need to improve our detection models for this “Intermittent idle turn off” the general reasons are: the engine hub motor are catching; hub motor cortex some frayed wires; dirty idle air hole; engine throttle position sensor problem; camshaft position sensor or crankshaft position sensor has problems; engine speed sensor problem or dirty; the engine electronic control unit in the idle speed control program in question, etc. In addition, if the quality of gasoline can also cause problems such failure. Idle stall usually does not cause any harm, because the engine running at idle, often when the vehicle is stopping, if the idle speed when the vehicle stalled in the slide, due to the distance from the obstacle in front, you can take appropriate measures to avoid dangerous . Of course, if you happen to occur when the emergency brake turn off, then on the great harm, because once the engine is off, the vacuum brake booster does not work, the vehicle’s braking performance greatly reduced, and the direction of the power unit failure, the vehicle’s steering is heavy, if coupled with your panic, it is difficult to avoid a car accident but if somebody did. Generally speaking, according to an auto injury lawyer you have a legal duty to keep a proper lookout, and you have a legal duty to exercise due care. These duties are somewhat analogous to riding with situational awareness– that is, being aware of what is happening in the road environment and how that may affect you. You do not have a legal duty to anticipate the illegal behavior of others on the road. Nevertheless, if you are observant of your surroundings, and are able to assess the potential dangers posed by the actions of others, regardless of whether those actions are legal or not, you will be able to respond to potential hazards before they become actual collisions.It’s impossible to avoid intersections, but attention to the safety precautions mentioned above will reduce your risk of virtually every type of collision in an intersection.

Wheel hub motor of electric vehivles
Wheel hub motor is one kind of electric motor of electric vehivles.
Electric bike hub motor has different forms based on their different frequencys and environmental conditions . Hub motors Characterized by different forms also have different features. Now widely used in electric vehicle motor permanent magnet DC motor. The so-called permanent magnet motor, is the use of permanent magnet motor coil excitation, do not use the coil excitation means. This eliminates the excitation coil power consumption when working to improve the mechanical and electrical conversion efficiency of the motor, this car is limited to the use of electric vehicles in terms of energy, can reduce the driving current, the line continued to extend the mileage. Electric vehicle motor according to motor power in the form of points, and the brush motor can be divided into two major categories of brushless motor; according to the mechanical structure of the motor assembly points, generally divided into the “teeth” (the motor speed is high, need to go through gear deceleration) and the “no teeth” (motor torque output without any slowdown) two categories.
Electric bicycle hub motor mechanical structures
Electric bicycle hub motor mechanical structures:
Brush motor and brushless motor have different energization principles, and their internal structures are not the same. For the electric bicycle hub motor, the motor torque output (whether through the reduction gear body) is not the same, then they will have different mechanical structures.
1, Common high-speed brush motor internal mechanical structure. This wheel hub motor from the built-in high-speed brush motors heart, reduction gears, clutch, wheel cover and other components. Brush with high-speed hub gear motor is within the rotor.
2, common low-speed brush motor internal mechanical structure. This wheel motor from the carbon brushes, commutator, rotor, stator, motor shaft, motor end caps, bearings and other components. Brush speed gearless hub motor is external rotor motor.
3, common high-speed brushless motor of the internal mechanical structure. This wheel motor from the built-in high-speed brushless motors heart, planetary roller friction, overload clutch, output flanges, end caps, wheel housings and other components. High-speed brushless geared hub motor is within the rotor.
4, common low-speed brushless motor of the internal mechanical structure. This wheel motor from the rotor, stator, motor shaft, motor end caps, bearings and other components. Low-speed brushless gearless hub motor is external rotor motor.
Brushless Motor with High Speed
Brushless Motor with High speed usually refers to high-speed motor speed over 10000 r/min motor. They have the following advantages: First, as high speed, so the electrical power density, and volume is much smaller than normal motor power, can effectively save material. The second is connected with the original motivation for the abolition of the traditional gear box, transmission, high efficiency, low noise. Third, because high-speed motor moment of inertia is small, so fast dynamic response.
High-speed machining technology attract more and more attention, not only get greater productivity, but also to obtain a high processing quality, and reduce production costs, brushless hub motor is considered the 21st century’s most promising advanced manufacturing technology one. In the advanced industrial countries, this technology has been widely used in aviation, aerospace and mold industry. In the past five years, the technology in China has made considerable progress. Is a prerequisite for high-speed cutting, high-speed machine is the machine trends. High-speed machine tools and virtual axis machine tools are a major breakthrough change.
electric motor systems -hub motor
Motor is to convert electrical energy into mechanical energy of the equipment, it is the use of power by the force coil in a magnetic field the phenomenon of rotation is made, distributed to each user at the motor power by using divided into bldc motor and the hub motor, electric motor systems most of the hub motor, can be synchronous or asynchronous motor motor (stator magnetic field speed and rotor speed is not in sync speed). Mainly by the motor stator and rotor components. Power wire in the magnetic field direction of movement by force and magnetic sense of direction with the current line (the magnetic field direction) direction of the. Motor works by magnetic force on the current role of the motor rotation.
Hub motor engine combustion
Hub motor engine combustion
There are several forms of design, construction and arrangement of the engine combustion cylinder interna.
Illustration of three types of configurations: a: in-line engine (L) b: hub motor (V), c: VR6 engine.
Votre engine layout is the V. It cylinders are grouped in two banks or rows of cylinders forming a V which converge on the same crankshaft. In these engines the intake air is sucked inside the V and the exhaust gases expelled from the sides.
Used engines from five cylinders, especially in front wheel drive cars, as it shortens the length of the hub motor in half. The opening of the V varies from 54 º or 60 º to 90 º or 110 º but the most common are 90 º and 60 º. Volkswagen VR6 engine is a V6 only 15 ° opening, which allows slightly reduce the length of the engine (transverse arrangement).
Engines with V available in most common are:
V6
V8
V10
V12
There are also, although very rare, V5 engine. For example, the 2.3 Seat Toledo second generation engine mounts V5.
inline engine Lel (L) is usually available in configurations from 4 to 8 cylinders, the engine is an online all cylinders aligned in a row, without movement.
oposiciónExisten cylinders in three different types of engines with cylinder opposition, commonly referred to the English term flat-cylinder engine:
1.The Boxer
2.la V-180,
3.The cylinder horizontally opposed engine.
Erroneously tend to speak either of these three types of engine cylinders in opposition or confused. In Germany, the term boxermotor is a group in which the boxer motor and motor with V at 180 ° are taken as a provision.
Diagram cylinder boxer engine opposition, first patented by Karl Benz in 1896.El boxer engine is used in the Volkswagen Beetle, Volkswagen Kombi, the Porsche 911, and is currently used by Subaru (in the Impreza, Legacy, etc.). and are usually between 4 and 6 cylinders.
The V-engine 180, configuration very similar to the boxer engine is used by some special editions of Ferrari and Alfa Romeo. The basic difference is that occasionally the engine with V at 180 ° do not use a stump long as the boxer, but the connecting rods share the same position on the crankshaft, making as a piston on the crank the other away, opposite of what happens in the Boxer in which the pistons move away and come together. The 180 ° V engine is used more than 8 cylinders where it has been more effective, while the boxer is used in pairs with less than 6 cylinders and therefore have partnered each other as the same type of disposition.
The engine cylinder horizontally opposed boxer another name.
The advantage of these three types of engines with cylinders in opposition is that they have a lower height and center of gravity lower than that of their peers online and “V” has a more compact, and its elements to be shorter guarantee stability. The main disadvantage Boxer engine is the most cost development and manufacturing because it requires greater number of parts.
Boxer engines are mounted on motorcycles as well as cars. Has been set in the entire series of BMW motorcycles and Ural motorcycles
Meanwhile, and less exclusive, the horizontally opposed cylinder engines have been used since the late thirties in thousands of small aircraft and suffered minor improvements like all piston engines, such as the injection system or the ever more efficient supercharger systems, however, are engines with a configuration of the cylinder head valve (OHV) and a relatively low compression (6.6:1 usually) compared to modern automotive engines, as they are used under other such conditions, likewise, there were no aircraft engines with variable geometry turbocharger and has been developing since the mid-eighties for cars and diesel power in these engines is experimental.
radial or star form this group are two types of engines, both with radial arrangement of cylinders: radial engines and rotary type engines, both used primarily in aircraft engines as static engines. The difference is that radial engines maintain the fixed block, turning the crank on the inside, while the rotary type, the crankshaft remains fixed and the entire block that road.
How is the arrangement HTambién H, which is a sort of hybridization of two-cylinder engines as opposed to using two crankshafts, leaving a bench above the other to generate power for a single axis transmission medium between the two crankshafts.
Form W WOTRO is available which is a kind of double V combined into three or four banks of cylinders and a crankshaft, which dates from the 1920s, and are used in some modern vehicles of the Volkswagen Group, such as Audi A8, Volkswagen Touareg and Volkswagen Phaeton.
Hub motor engine History
One of the first hub motor engines as it is understood today was the steam engine, which is produced in the superheated steam in a boiler which then expands into a cylinder, produces a thrust of a piston. This motion, made alternative arrangements with other mechanics, can be transferred to a wheel or a flywheel through a connecting rod and crank mechanism. In the late nineteenth century, the development of the internal combustion engine made possible the great development of the automotive industry and, later, the birth of the aviation industry.
Chicago, on Lake Michigan in Illinois, is one of the largest cities in the United States. Chicago Illinois is famous for the award winning artists that produce stellar paint jobs on custom vehicles. Chicago Autohaus, is a body shop in the Chicago area of Wicker Park, they have several award winning auto paint specialists on staff ready to help.
After the Second World War, the aircraft used for flight demanded the development of jet engines, while the birth of space flight allowed the great development of rocket motors and, in particular the chemical rocket engine.
In recent years the requirements of interplanetary flight are leading the search for new solutions, particularly in the field of rocket propulsion engines do not like the sails chemical space.
In the field of engines for automotive applications, but the research is strongly oriented toward solutions that reduce fuel consumption and emissions of pollutants into the environment.
DisposizioneIl hub motor engine can be ordered:
Longitudinal, when the engine is placed perpendicular to the shaft that drives the final rotation, or more generally is parallel / linear displacement generated at the axially
Transverse, when the engine is placed parallel shaft that drives the final rotation, or more generally is perpendicular to the linear displacement generated
Hub motor Control Devices
Different symbols autodiagnosiI heat engines, especially those intended for transportation (cars, trucks and motorcycles), have more control devices to indicate the various anomalies, including:
Self-diagnosis, is used to indicate any failure of the engine, generally has a specific meaning
Temperature, controls the maximum temperature, indicating when the threshold exceeds the maximum operating
Oil, this light does not mean it has the same meaning for any type of engine and usually indicates either bad management or wrong level of the same.
