How many parts are there in the car? In fact, this question is not a very accurate standard answer ...
It is estimated，Generally, the car is assembled by about 10,000 irreversible independent parts。Special car with extremely complicated structure，such as F1 car, etc.，The number of independent parts can reach 20,000。
Of course，It is estimated that no one can accurately calculate the number of parts of a car。The more the number of parts of the car，It does not show that the better the performance of the car，Instead, it means that its reliability will be more difficult to guarantee。 Cars are generally from the engine、chassis、Four basic parts including the body and electronic and electrical equipment。Seabet The engine is the power device of the car, mainly by the body,Stranging link mechanism、gas distribution mechanism、Cooling system、Lubrication、The composition of the fuel system and the ignition system (the diesel engine does not ignite)。 ● Cooling system: Generally from water tank、Water pump、radiator、Fan、Temperesental、Water temperature meter and water release and switch composition。The car engine uses two cooling methods，That is air cooling and water cooling。Generally car engines use anti -freezing liquid cooling。 ● Lubrication system: The engine lubrication system is oil pump, filter,Machine oil filter、Oil channel、pressure limit valve、Machine oil meter、Sension plugs and oil ruler composition。
● Fuel system: gasoline engine fuel system from a gasoline tank、gasoline meter、gasoline pipe、gasoline filter、Gasoline pump、Oil Jet Mouth、Air Filter, input exhaust manifold, etc. ● Ordering system: from the ignition power supply、ignition switch、ignition coil、Spark plug、High -voltage line 鞥 composition。 Car chassis The car chassis is mainly used by transmission, driving system, steering system,brake systemComposition.
● Transmission system: mainly by clutch, transmission,Wanxiang Festival, transmission shaft and drive bridge.
The function of the clutch is to stabilize the engine's power with the transmission device or temporarily separate，so that the driver can start the car、Parking、Delivery and other operations。 The transmission is from seabet loginthe transmission shell、Garway Cover、The first axis、Two axis、middle shaft、inverted axis、Gear、Bearing、Composition of machinery and other parts of the manipulation agency，Used for automotive transmission、Change output torque。 ● Driving system: from the frame、Bridge、Suspension and wheels, etc.，Its basic function is to support the quality of the whole car and ensure the driving of the car。 ●Steel Spring and Shock absorber: The role of steel plate spring is to keep the frame and body and wheel or bridge。The role of a shock absorber is to ease the vibration when the car is shocked by the shock。Shock absorbers and steel plate springs combined with。 ● Steering system: from the steering wheel、Treator、Steering Festival、Steering Armor、horizontal pull rod、Straight hoeing, etc.，The role is steering。 ●Pre -wheel positioning: In order to keep the car stable and straight,，Turn to lightweight，Reduce the wear of tires and steering parts during driving，front wheel、Turn to the main sales、The installation between the three front axis has a certain relative position，This is called "front wheel positioning"。It includes leaning after the main sales、Production and sales inside、The front wheels front bouquet。The front beam value refers to the difference between the front edge distance of the front and front of the two front wheels than the distance from the back side.。 ● Brake system:The role of the braking system is to enable the driving cars to compulsory deceleration or even parking according to the requirements of the driver; make the stopped cars stabilized at various road conditions (including on the slope); to make downhill downhill; make the downhill downhill The speed of the car is kept stable。At present, domestic car manufacturers use more use on small and medium -sized finished product cars for the front plate and rear drum -type brake system，Some models are four -wheel disk brakes，Compared to the drum -type brake，disc brakes are more advanced，The braking performance is better。 Car body and attachment The role of the car body is mainly to protect the driver and constitute a good air mechanical environment。Automotive body structure in form，It is mainly divided into non -loading、bearer、Semi -load。Automotive body composition parts include seabet appthe engine cover、The roof lid、suitcase lid、Wings board、Aterior Plate Plate, etc.。 ● Engine cover: The structure of the engine cover is generally composed of the outer board and the inner plate，In the middle clip to heat insulation material，The inner plate plays a role in enhancing rigidity，The geometric shape is selected by the manufacturer，Basically in the form of skeleton。The engine cover is generally flipped backward，There are also a small part of it flipped forward。 ● Dome cover: The cover of the top of the carriage。For the overall rigidity of the car body，The top cover is not a very important part，This is also a reason to allow opening a sunroof on the roof cover。From a design perspective，What is important is how it is with the front、The rear window frame and the junction of the pillars are smooth transition，To get the best visual sense and the smallest air resistance。Of course，For the roof cover of the car, there should be a certain strength and stiffness，Generally add a certain number of enhanced beams under the top cover，The inner layer of the top layer is laid -up thermal pad，To prevent the transmission of the outside temperature and reduce the transmission of noise during vibration。 ● Character lid: The luggage also has an outer board and the inner board，Inner plate has enhanced tendons。Some cars called & QUOT; Sidam Half & Quot;，Its suitcase extends upward，Including the rear -gery glass,，Increase the opening area，Form a door，Therefore, it is also called back door，This can not only maintain a sedan -car shape and can easily store items。 ● Wingsplate: Wing board is the body plate covering the wheels，It is named because of the shape and position of the old body.。According to the installation location, it is divided into front -panels and rear fenders，The front fender is installed at the front wheel，Therefore，The problem of no wheel rotation and rubbing in the wing board，But for the consideration of aerodynamics，The rear wing board is slightly arched arc protruding outward。At present, some sedan panels have become a whole with the body body。 ● Aterior fence: The front fence refers to the partition between the engine compartment and the carriage，It and floor、Aterior Pillar connection，Install the car body，Under the front of the front seabet myenclosure。There are many holes on the front fence，As a pull -up line for manipulation、Ploves、Pipelines and wire beams pass through the pass，Also cooperate with the pedal、Fangwen Machine Pillar and other parts of the installation location。 Electronics Automotive electronics is the total name of the vehicle body automotive electronic control device and the vehicle electronic control device。 Vehicle electronic control device includes: engine control system、The chassis control system and body electronic control system。These are all sensors、Micro -processor MPU、Activator、Tens or even hundreds of electronic components and components of electronic control systems。 Car Electronic Device in the car includes: battery、Generator、regulator、Starting motor、ignition system、Instrument、Lighting device、Audio device、Wiper wiper, etc.。
