Engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engine (reciprocating piston engine) and external combustion engine (Stirling engine, steam engine, etc.). ), jet engines, motors, etc.
For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is suitable for both power generation devices and complete machines (such as gasoline engines and aero-engines) including power devices. The engine was first born in Britain, so the concept of engine also originated in English. Its original meaning refers to "a mechanical device that generates power".
2. Chassis
Chassis refers to the combination of transmission system, driving system, steering system and braking system, which supports and installs the automobile engine and its parts and assemblies, forms the overall shape of the automobile, bears the engine power and ensures normal driving.
Step 3: body
Body refers to the part of the vehicle used to carry people and goods, and also refers to the whole vehicle. The body of some vehicles is not only the driver's workplace, but also the place to accommodate passengers and goods. The car body includes windows, doors, cockpit, passenger compartment, engine compartment and luggage compartment.
There are several types of body modeling, such as box type, fish type, ship type, streamline type and wedge type, and the structural forms are divided into single box type, hatchback type and sedan type. Body modeling structure is the body language of the vehicle, and its design will directly affect the performance of the vehicle.
4. Electrical equipment
Electrical equipment refers to generators, transformers, power lines, circuit breakers and other equipment in the power system.
5. tires
Tire is a round elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. Usually installed on the metal rim, it can support the car body, buffer the external impact, achieve contact with the road surface and ensure the driving performance of the vehicle.
Tires are often used in complex and harsh conditions. They are subjected to various deformations, loads, forces and high and low temperatures during driving, so they must have high bearing performance, traction performance and cushioning performance.
Extended data
1680, Newton, a famous British scientist, conceived a scheme of a jet car, which used steam from a nozzle to propel the car, but failed to make it into a real object.
1769, a Frenchman, N·J· Juno, built a three-wheeled car driven by steam generated by gas combustion. .
1879, German engineer karl benz successfully tested the two-stroke experimental engine for the first time. 1June, 883, founded "Ben Ci Company and Rheinland Gas Engine Factory". 1in June, 885, he manufactured the first Ben Ci patented motor vehicle in Mannheim, which was a three-wheeled vehicle with a two-stroke single-cylinder gasoline engine of 0.9 HP. This car has some basic characteristics of modern cars, such as spark ignition, water cooling cycle and steel tube frame.
18861On October 29th, German engineer karl benz applied for a patent for his motor vehicle. In June165438+1October of the same year, Karl Benz obtained the German patent (patent number: 37435a). This is considered to be the first modern car in the world.
