    1. 1.  The mechanisms that carry power from the engine to the drive wheels.
    2. 2.  Clutch. - The device that connects and disconnects a shaft from its drive while the drive mechanism is running. - The device that engages and disengages power from the engine to transmission.
    3. 3.  Transmission – a metal case containing an assembly of shafts and gears used to transmit power from the engine to the drive shaft of automotive vehicle. - Provides gear ratios. Transaxle – a power-transmission device attach to one end of the engine that combines the function of the transmission and the drive shaft.
    4. 4.  Drive Shaft (Propeller shaft)- Transfers power from transmission to the differential. Differential -A gear assembly between axles that permits one axle to turn at different speed than the other.
    5. 5.  Hybrid powertrains appear to be promising for Class 8 urban use trucks where stop-and-go driving is prevalent, or in hilly or mountainous areas
    6. 6.  A torque tube system is an automobile driveshaft technology. The "torque tube" transmits this force by directly coupling the axle differential to the transmission. A ball and socket type of joint called a "torque ball" is used at one end of the torque tube to allow relative motion between the axle and transmission due to suspension travel.
    7. 7. Capsule of shoulder-joint (distended). Anterior aspect. 1: Ball and socket joint; 2:Condyloid joint (Ellipsoid); 3:Saddle joint; 4 Hinge joint; 5: Pivot joint;
    8. 8.  Since the torque tube does not constrain the axle in the lateral (side-to-side) direction a panhard rod is often used for this purpose. The combination of the panhard rod and the torque tube allows the easy implementation of soft coil springs in the rear to give good ride quality
    9. 9.  the torque tube is hollow and contains the rotating driveshaft. Inside the hollow torque ball is the universal joint of the driveshaft that allows relative motion between the two ends of the driveshaft. In most applications the drive shaft uses a single universal joint which has the disadvantage that it causes speed fluctuations in the driveshaft when the shaft is not straight.
    10. 10.  Nashs post-war Airflyte model. 1948 American Motors (AMC). Rambler Classic and Ambassador. 1966 1961-1963 Pontiac Tempest. Peugeot 504 and the Volvo 300 Series. Sprintcars and Midget cars. The C5 and C6 Chevrolet Corvette, Lexus LF-A, Porsche 924, Porsche 928, Porsche 944, Aston Martin DBR9, Aston Martin DBS, Aston Martin DB7, and upcoming Mercedes AMG SLS
    11. 11.  The Hotchkiss drive uses two universal joints which has the effect of canceling the speed fluctuations and gives a constant speed even when the shaft is no longer straight. Hotchkiss drive………….
    12. 12.  The Hotchkiss drive is a system of power transmission. FR layoutont-engine, rear-drive cars in the 20th century. French automobile firm of Hotchkiss.
    13. 13.  During the early part of the 20th century the two major competing systems of power transmission were the shaft-drive and chain-drive configurations. It uses universal joints at both ends of the driveshaft. allows the use of simple cross-type universals. universal should be a constant velocity joint.
    14. 14.  allow a rotating shaft to transmit power through a variable angle, at constant rotational speed. Early front wheel drive systems such as those used on the Citroën Traction Avant and the front axles of Land Rover. provide a flexible coupling in some propshafts.
    15. 15.  In the Hotchkiss drive, splines eliminate thrust transmitted back up the driveshaft from the wheels, allowing simple rear-axle positioning using parallel leaf springs. In the torque tube type this thrust is taken by the torque tube. Some Hotchkiss driveshafts are made in two pieces with another universal joint in the center for greater flexibility.
    16. 16.  1984-1987 RWD Toyota Corolla (i.e., Corolla SR5 and GT-S). his design was the main form of power transmission for most cars from the 1920s through the 1970s. Presently (circa 2008), it remains common in pick- up trucks and sport utility vehicles.
    17. 17.  Wikipedia.org Automobile Engineering: A General Reference Work. www.calstart.org. How stuff works.
