Chapter III The Manufacturing processQuestion：1.How much you know about the manufacturing process of automobiles？2.Have you ever visited a vehicle production workshop or watched related short films on TV?If yes,how do you feel about your visit or the filmsMoving production line Robots on busy workThe Manufacturing Process ChassisBodyPaintInterior Assembly MateWelding of AutomobileQuality ControlThe Manufacturing processThe manufacturing process begins with 4000 components supplied by many suppliers,company-owned or outside.chassis installation Assembly line completes front and rear suspensions,gas tanks,rear axles and drive shafts,gear boxes,steering box components,and braking systems.body installation The floor pan is the largest body component.First the left and right quarter panels are placed onto the floor pan。
then the front and rear door pillars,roof,and body side panelspainting processThe multi-step painting process requires inspection,cleaning,undercoat dipping,drying,topcoat spraying,and baking.interior assemblyInterior assembly includes two steps,assembling the windshield and the rest.Workers assemble all of the instrumentation and wiring systems,interior lights,seats,door and trim panels,headliners,radios,speakers,all glass except the automobile windshield.Robots place the windshield into the body windshield frame.mating process,Assembly workers bolt the car body to the frame.Once the mating takes place the automobile proceeds down the line to receive final trim components,battery,tires,antifreeze,and gasoline.checking processThere its engine is audited,its lights and horn checked,its tires balanced,and its charging system examined.ExercisesRearrange the following manufacturing steps in the correct order.A.The left and right quarter panels are robotically placed onto the floor pan.B.Assemble all of interior lights.C.Clean the body shell.D.Await shipment to its destination.E.Install complete front and rear suspensions.F.Bolt the car body to the frame.KEY E、A、C、B、F、DDirections:Read the passage and match the topic in Column A with the related information in Column B.Column A 1.Chassis2.Body3.Paint4.Interior assembly5.Mate6.Check Column B a.The shell of the vehicle is built with the floor pan moving down th assembly line.b.Gas tanks,rear axels and drive shafts,gear boxes etc.are installed onto the chassis.c.This process includes cleaning,undercoat dipping,drying etc.d.Check the engine,lights and horn.e.Assemble the wiring systems.f.Bolt the car body to the frame.g.Take a water test.h.Install automobile windshield.i.Install battery and tires.Automobile EngineMatching ExerciseEngine block Spark plugExhaust manifoldFly wheelPVC hoseExhaust pipe Filter hoseSpark plug coverfanSpark plug cable发动机机体发动机机体排气歧管排气歧管飞轮飞轮火花塞高压线火花塞高压线PVC 软管软管排气管排气管火花塞盖火花塞盖滤清器软管滤清器软管车轮车轮火花塞火花塞Matching ExerciseValve spring Water pumpFan beltPulley Radiator hoseGas pump Gas linedistributor Dip stick Cylinder head cover气门弹簧气门弹簧风扇皮带风扇皮带带轮带轮汽缸盖罩盖汽缸盖罩盖散热器软管散热器软管气泵气泵分电器分电器燃油管路燃油管路机油量尺机油量尺水泵水泵 Types of EngineIN-LINE 4 CYLINDER6-CYLINDER V ENGINEFLAT4 How an Engine Works ChassisPower train system Brake systemSteering systemSuspension system1.Power Train SystemClutchTransmissionUniversal JointsDrive shaftFinal driveDifferentialHalf-shaft2.Steering SystemSteering wheelSteering shaftSteering gearSteering knuckleTrack rodtie rod3.Suspensiontie rodstabilizer barshock absorbercoil springtrailing control4.Braking SystemDrum brakes 鼓式制动器鼓式制动器Disc brakes 盘式制动器盘式制动器Brake discpistonFixed caliperhydraulicBrake padWheel CylinderBrake drumTrailingshoeAnchor pinAnchor pinLeading shoeMatching ExerciseFinal driveSteering wheelStabilizer barTrack rodHandle ClutchSteering shaftBrake lineBrake pedalSteering gear离合器主减速器转向器制动管路制动踏板方向盘转向横拉杆横向稳定器拉手转向轴 。
