---------------------------------------------------------------最新资料推荐------------------------------------------------------ CHAPTER 4 Braking System and body constructionA separate frame must be light yet strong enough to resist the various loads and road forces. Commercial vehicles normally use a separate steel frame to provide the rigidity needed to support the various loads. The two long side members of channel section are riveted to a number of cross members to give a low weight frame which offers great resistance to bending, twisting.分离式车架必须足够轻巧而且结实，分离式车架必须足够轻巧而且结实，以承受变化的载荷和路面作用力。

CHAPTER 4 Braking System and body constructionMost cars use a unitized body construction, a combined body and frame. Unitized body construction is lighter than body/frame construction, but noisier. Rubber mounts are used between the body section and mechanical parts to absorb vibrations. The floor pan is made of sections that support the rear suspension and the transmission.多数轿车采用承载式车身，多数轿车采用承载式车身，也就是车身和车架融为一体。

---------------------------------------------------------------最新资料推荐------------------------------------------------------ CHAPTER 4 Braking System and body construction Modern cars have a blend-air system that mixes warm and unwarmed air to heat the car. The "heart'' of the system is the heater core. Hot engine coolant flows from the radiator, through the water pump hoses, and to the heater core. Therefore, the heater core is always hot. The temperature of air entering the passenger compartment is controlled by the amount of air moving through the heater core. This heated air is blended with fresh, cool air that bypasses the heater. Small doors in the heating system regulate the air-flow. Control levers on the dash panel open and close these doors to direct air to the heat ducts and window defrosters.多数汽车采用加热过的或未加热过的空气的混合起来加热汽车。
