subject: Automobile Basic Structure [print this page] The braking system is the most important system in cars. If the brakes fail, the result can be disastrous. When stepping on the brakes, the driver commands a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes.Brakes are actually energy conversion devices, which convert the kinetic energy (momentum) of the vehicle into thermal energy (heat).
Steam car-refers to power device drivers, or Traction on the road, For workers with or used for transport by Load items and the project designed Assignment of wheeled vehicles ,The car is by all sorts of institutions and the device component.Although the various agencies, loadingThe structure and installation for position DuoZhong diversity,But the overall structure and the structure of the main partsHave the same basic rules and similar job.
By the following four on the whole car composed of:
1, engine: car power unitwill fuel in gasThe heat energy produced is burning in cylinder into a machineSoldiers, and then through the chassis of the power transmissionSystem driver the car.
2, electrical equipment: provide power supply, starting the engine, pointBurning fuel, monitoring work operation condition,Lighting, improve the driving safety, fuckThe stability and comfort, and so on.
3,bottom plate: will transfer the power of the engine output to floodingDongLun, to make the car produce movement, and insuranceCard moving.
4, car body: to take personnel, loading goods, installation engine, chassis of each system and electrical appliancesEquipment
The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The primary purpose of the brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by when a separate parking brake foot pedal or hand lever is set.
The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder (Figure).
Basically, all car brakes are friction brakes. When the driver applies the brake, the control device forces brake shoes, or pads, against the rotating brake drum or disks at wheel. Friction between the shoes or pads and the drums or disks then slows or stops the wheel so that the car is braked.
