Modern Automotive Technology: Everything You Must Know (A to Z) Part 2

Figure 1-21. It is a hollow metal tube with two or more universal (swivel) joints. 

The universal joints allow the rear suspension to move up and down without damaging the drive shaft.

Rear Axle Assembly

The rear axle assembly contains a differential and two axles. 

The differential is a set of gears and shafts that transmits power from the driveshaft to the axles. 

The axles are steel shafts that connect the differential and drive wheels, Figure 1-21.

Transaxle 

The transaxle consists of a transmission and a differential in a single housing.

Although a few rear-wheel-drive vehicles are equipped with transaxles, they are most commonly used with front-wheel-drive vehicles, Figure 1-22. Both manual and automatic transaxles are available.

The internal parts of a modern transaxle assembly are illustrated in Figure 1-23. 

Front Drive Axles

The front-drive axles connect the transaxle differential to the hubs and wheels of the vehicle. 

These axles are equipped with constant-velocity joints, which allow the front wheels to be turned to the left or right and to move up and down.

Suspension, Steering, and Brake Systems

The suspension, steering, and brake systems are the movable parts of the chassis. 

They bolt or anchor to the frame and provide important functions that will be explained in the following sections.

Suspension System

The suspension system allows the vehicle’s wheels and tires to move up and down with little effect on body movement. 

This makes the vehicle’s ride smooth and safe. The suspension system also prevents excessive body lean when turning corners quickly. 

As you can see in Figure 1-24, various springs, bars, swivel joints, and arms make up the suspension system.

Steering System 

The steering system allows the driver to control vehicle direction by turning the wheels right or left. 

It uses a series of gears, swivel joints, and rods to do this. Study the names of the parts in Figure 1-24.

Brake System

The brake system produces friction to slow or stop the vehicle. When the driver presses the brake pedal, fluid pressure actuates a brake mechanism at each wheel. 

These mechanisms force friction material (brake pads or shoes) against metal discs or drums to slow wheel rotation. Figure 1-25 shows the fundamental parts of a brake system.

Accessory and Safety Systems

Common accessory systems include the air conditioner, sound system, power seats, power windows, and rear window defogger. 

Common safety systems include seat belts, airbags, and security systems.
