SUSPENSION and DRIVETRAINS Transportation Systems Suspension Systems use

SUSPENSION and DRIVETRAINS Transportation Systems

• • • Suspension Systems use: Shocks Struts Coil springs Bushings Stabilizer and sway bars So that they: • Provide comfort and control for the automobile.

Springs: provides RIDE HEIGHT and overall stiffness TYPES: • • coil torsion air springs mono leaf

LOWERING SPRINGS

• Shocks: handle the impact force of bouncing up and down. Some are even tuned so that you can change the damper to make them stiffer or softer!

• STRUTS: Coil over shock setup Provides Stiffness and ride control. “Stable and Efficient”

• Strut Tower Brace: in the engine bay…helps keep the body straight, level and stable in turns. There also REAR braces for the trunk as well.

• Sway Bar – connects the front and rear suspension together, helps with keeping the car level in turns. (The wider diameter bar, the more stiff)

Bushings: connects every suspension component together. The stiffer and stronger the bushing, the more positive the suspension feel is.

Typical Suspension System contains Average control and performance

Independent Suspension System contains Much better!! Very stable! Recommended!

BASIC SUSPENSION SETUP

INDEPENDENT SUSPENSION

LOWER YOUR CAR… • Lowering your car may be a bad idea. Always make sure that you know that the roads here in Rochester are bumpy • A lowered car can bust not only a rim, but the front and rear fascias/ bumpers!

Drive Train Parts

The clutch smoothly engages a spinning engine to a non-spinning transmission by controlling the slippage between them VIDEO

Torque Converters uses Hydraulic pressure to engage the transmission. When the car is idling, the torque is very low, so the pressure on the brake pedal can be very low. When more torque is applied, the converter slips until it connects fully.

Manual Transmissions need to be physically shifted into each gear. The gear lever supplies the linkage necessary to move the forks to connect up the correct gears. VIDEO!

Opposed to a Manual, an automatic transmission uses planetary gear sets to allow slippage between the engine and transmission. The transmission is always slipping until more torque is applied. VIDEO

The Differential transfers the rotating driveshaft 90 degrees to rotate the rear wheels. The driveshaft is perpendicular to the differential.

The driveshaft connects the Transmission to the Differential. The rotating transmission spins the driveshaft which in turn spins the differential

The front wheel drive transaxle converts the rotation of the engine to power the front wheels. The engine is turned transversely so the transmission sits underneath.

The Transfer case connects both the front and rear wheels together in 4 wheel drive setups. Usually it can be controlled by a switch or gear lever.

Front Wheel Drive Train REVIEW Transaxle spins the FRONT WHEELS SPIN ONLY!

Rear Wheel Drive Train REVEW Differential turns the REAR WHEELS TURN ONLY!

Four Wheel Drive Train REVIEW Transfer case allows the rotation of ALL WHEELS
