Lamborghini-Murcielago LP640


Wall Street used the bull to represent the prosperous market,and increase the investor confidence. But today not for the stock market. What do you think the bull can be for auto makers?



Fast & Speed

Italy

Lamborghini Automobile

V12 Engine Block. What an amazing engineering !!

The edge will be removed.

Crankcase
 
Remove the bottom of Crankcase for installing crankshaft.

Crankshaft Manufacturing

Crankshaft Inspect

Install the Crankshaft on the Engine Block.

Install the Piston. 

Bolt the Connecting Rod and Crankshaft

Gasket

Those camshafts had not been ground yet.

Grind Camshaft

Inspect Camshaft

Cylinder Head

CNC bore the Cylinder Head

CNC bore the Cylinder Head

Water washed the Cylinder Head

Ready for inspection

Use the borescope to inspect

Inspect

Check Balance

Check Balance

Install Cylinder Head.
Note that the different color of the valve.

Engine

V12 Engine

Pressure check

Valve Cover

Tight Valve Cover Up

Intake Manifold check.
**What need to be check ???? no idea.

Intake Manifold. Compare to Ferrari V12. See the difference.

Exhaust Pipe

Install Transmission

Lamborghini and Tractor. Lamborghini is associated with the tractor. Do you believe in ?
See the antagonism history between Lamborghini and Enzo Ferrari. Make me laugh !!!!!!
Ferrari used the same clutch with the tractor.

Send the car body to paint

Primer

Paint

Install the Radiator

Sound Absorb Material

Heat Shield.  Keep the heat outside the cabin.

Front Differential

Drivetrain. All Wheel Drive.

Front Alxe.

Double Wishbone Suspension

Disc Brake and Caliper.

Caliper Bracket Bearing installation

Using the hydraulic machine to put the bearing onto the bracket

Dry Sump Oil Tank

Driver-side Panel used for oil cooling.

Oil Radiator

Front Bumper installation.

Alcantara

Glue the Dashboard.

Leather can be manipulated by heat.

Engine engaged the chassis

Scissor Doors.
From the onside of the car, you have no almost visibility.
So sitting on the doorsill you have complete total visibility of the car.

The wheel made in the U.S.A. Cleveland Ohio.

Alcoa

Aluminium Column

Before to the forged process, the aluminium went into the furnace to heat
and to be softened.

Forged the aluminium.
1.Oil lubricant is sprayed onto the mold and ignited by heat.
   The oil keeps the aluminium from stcking to the steel mold.
   Lubricants greatly influence friction and wear.
   Then 4.5 million kilograms of pressure slam down on the wheel from high above and,
   shaping the aluminium into something resembling a wheel.
2.The aluminium went into a second to refine its shape further
    with 4.5 million kilograms of pressure.
3. Pistons manufacturing used the same way
    Refer to "McLaren MP4"

Advantage and Know-How

The Murcielago's wheel are forged, a process invented by Alcoa in 1984.
With forging, aluminium is not melted into liquid like casting.
Instead, it's stamped by the mold. Forging makes a stronger, lighter wheel than casting.
Because it has less imperfections inside the material.
I could have a thinner cross section, and make a light part with the same final mechanical properties.

Outline of forging
 
1.Billet Slug Preform (Shearing Sawing, Cutting off Machining)
2.Furnaces ( Hot Warm Isothermal ) Heated dies
3.Forgeability ( Open die ) Presses, Forging machines, Die design and manufacturing,
   Lubrication
4.Trimming, Machining, Heat treating, Finishing, Cleaning, Inspection.


After the forged, and then shape the wheel.

Punch the center out.

K-M-S Industries. Ship the wheel to machine.

CAM (Computer Assist Engineering)

Machine the wheel.
Five nut holes--> Five Double-Spokes

One piece forged wheel featured the lightest and strongest structure.
Compared to the Die-Casting.

Install the wheel to the Lamborghini.
Ready to Roll.

Crash Test. Due to the engine is behind the driver, the energy must be absorb by
the crumple zone of the front chassis as well as the Airbag.

Install the spoiler.

The rear spoiler increased the down-force to the car.

Roll Test

Road Test.
