Drivetrain parts are a collection of components that work in unison to transfer power from the transmission to your wheels, propelling your vehicle forward. They include transmission, differential, driveshaft, axles and CV joints.
The drivetrain of your truck includes numerous small parts such as yokes that connect the driveshaft to other driveline components. These little components play a vital role in its operation.
Brakes
Brakes are an integral component of truck drivetrains. They help slow or stop the vehicle while also protecting against rolling over or becoming stuck in its track. Should the brakes fail unexpectedly, this could cause severe injury both to drivers and vehicles alike.
Truck brakes use air to apply pressure to their calipers and drums in order to slow or stop their vehicle. Air is stored in tanks underneath the truck, then when you press your brake pedal it travels through air brake chambers directly to calipers or drums in order to provide brake control.
As soon as you push the brake pedal, air pressure moves a gold rod that pushes a slack adjuster into position – this adjuster calibrates and ensures that the internal spring mechanism works properly.
Commercial trucks feature multiple brake chambers which convert air pressure into mechanical force, matching each wheel they control perfectly to avoid serious imbalance issues. It is critical that these chambers function correctly to avoid serious imbalance issues.
Additionally, truck braking systems must pass a series of rigorous tests under various conditions and circumstances, including freezing temperatures and heavy traffic loads. They must remain functional and effective under such pressure.
As with all parts of a truck drivetrain, having an in-depth knowledge of how to service and repair brakes is vitally important for keeping other drivers safe on the road. Furthermore, knowing how to check system components regularly for damage or failures will save time and money in the long run while keeping your truck running efficiently.
Clutch
The clutch is an integral component of your truck drivetrain that connects its engine, transmission and driveshaft. It optimizes engine performance while increasing fuel economy while guaranteeing top-of-the-line on-road safety.
Your clutch system includes several components, including the clutch disc and pressure plate. The disc is composed of steel plates layered with friction material that works to compress between your flywheel and pressure plate when you press on the clutch pedal.
A pressure plate is attached to the flywheel and contains a diaphragm spring. This allows the pressure plate to loosen its clamping force on the clutch disc when you depress your pedal.
Throwout bearings are another crucial element, pressing against the pressure plate when you depress the clutch pedal to create an opening between them and the flywheel, which allows your clutch disc and transmission to spin freely.
If your clutch pedal remains “floating” after gear changes, this could indicate binding issues with its pressure plate, throw-out bearing or release mechanism. Furthermore, grinding noises or squealing sounds from your clutch may indicate this condition.
Clutches are built to last, but eventually they wear down and require replacement. By following these simple tips and performing regular inspections, however, you can extend its life and keep your truck operating smoothly on the road.
Transmission
Transmissions are mechanical systems designed to manage how much torque from an engine reaches its drive wheels and also ensure a low RPM range below redline (the maximum speed before any damage occurs) is maintained for safe engine operation.
Truck transmissions consist of four main parts, an input shaft, pump, turbine and output shaft. The input shaft connects directly to the engine and clutch pack while pump supplies fluid for transmission to torque converter. Finally, turbine-like turbine sits inside torque converter to receive and utilize fluid sent from pump.
Transmissions require various seals made of different materials; from neoprene and rubber, to other materials like nylon. A front seal protects its connection with a torque converter while rear seals contain fluid between transmission and output shaft.
Most cars use an advanced transmission computer system that monitors sensor data throughout the car in order to automatically shift gear ratios when necessary for optimal fuel economy and power. With this information, the torque converter module (TCM) seamlessly disengages first gear upon acceleration to accommodate engine load needs by engaging second gear seamlessly.
Collars are also an essential component of transmissions, connecting input shafts to clutch packs and gears, providing friction during gear changes. Drivers may hear grinding noises during gear changes due to this component’s primary role as the source of friction.
Selecting the appropriate transmission is essential to keeping your truck performing at its best, which is why JEGS offers a selection of performance transmissions and drivetrain parts so you can upgrade it with components designed specifically to improve performance.
Axles
Axles work together with other components of the truck drivetrain to power and move the vehicle. Additionally, they protect it against sliding on snowy or icy terrain.
Axle configuration decisions vary based on factors like applications, driving surfaces and weather conditions, fuel efficiency, load weights and driver preference. While certain designs are often utilized, others require special consideration.
Full floating and semi-floating axles are two primary axle types. Full floating axles consist of an independent wheel hub system connected directly to an axle shaft while semi-floating axles combine both elements into one unit.
Full-floating axles typically feature bearings both inside and outside the wheel hub; in contrast, semi-floating axles usually only contain bearings inside of their wheel hubs.
An important consideration in axle specification is axle ratios. Higher ratios enable greater mileage with each turn of the engine. Lower gear ratios reduce power and fuel economy.
Axle ratios not only impact how far a truck can travel with every turn of its engine, but they can also have an effect on how much torque is produced by that same engine. Specifically, as more gears in an axle lead to less torque being generated; hence a truck with a high axle ratio may be less capable at towing heavy loads effectively.
Fleet managers must understand the differences among various types of axles and how they impact truck drivetrain performance in order to select appropriate components for their fleets and maintain peak vehicle performance. Understanding these distinctions will assist them in selecting suitable axle components and keeping vehicles operating optimally.
Steering
Steering systems are one of the key elements of truck drivetrain systems. Without precise and responsive steering, it is impossible to safely or efficiently maneuver a truck.
Your truck’s front end is connected to its steering box or rack and pinion through a series of linkages, and if these worn out linkages start malfunctioning you could experience loose or sloppy steering.
Some steering issues can be addressed with simple steering rod adjustments; more severe issues may necessitate replacing the entire system. Since these components are critical for driving safely, if any fail or leak, it’s wise to get them repaired immediately.
There are various steering systems currently used on vehicles, but one of the most prevalent systems is known as a worm-and-sector or rack-and-pinion system. This type of steering uses a worm gear to translate rotary steering wheel motion into linear motion that drives tie rods – ultimately turning your front wheels.
Power steering systems have become an attractive feature of modern vehicles. These systems utilize electric motors with control modules that collect information about speed, steering wheel position, and more so as to determine how much assistive force the system should apply when turning the steering wheel.
Power steering systems can be invaluable in many circumstances, from driving on slippery or wet surfaces to snow and rain conditions. To maintain its effectiveness and ensure proper performance, regular fluid changes must take place; please refer to your vehicle owner’s manual for information regarding when this should take place; in general though, every five years or 50,000 miles is recommended as the minimum frequency for fluid replacement.
