All You Need to Know About Commercial Truck Steering Joint
What is a Commercial Truck Steering Joint?
- A Commercial Truck Steering Joint also called a steering universal joint is a device used in commercial trucks for steering.
- It connects the steering column to the steering linkage, allowing it to move with the steering wheel and turn the front wheels.
- It also helps reduce wear on both parts and provides smoother handling.
- The joint consists of two metal plates connected by a ball-and-socket arrangement, which allows for smooth movement when turning. In addition, this design ensures an even distribution of force throughout the entire system, helping keep components from wearing out prematurely.
- Proper maintenance and lubrication are essential for keeping this part working properly, as failure can result in severe damage to the vehicle or injury to the driver.
- Overall, a commercial truck steering joint is essential to any commercial truck, helping ensure smooth and safe operation.
- Step 1: The steering wheel is rotated.
- Step 2: The torque sensor senses a torque signal, which is then processed by the ECU.
- Step 3: The ECU supplies an electric current to the motor based on the torque signal and the speed of the vehicle.
- Step 4: The motor's rotational torque is amplified by the reduction gear, before being sent to the pinion.
- Step 5: The torque generated by the pinion on the power-assist side (supplemental steering torque), as well as the torque from the pinion on the steering wheel side (steering rotating torque), is converted into a rack axial force to control tire direction.
What does the steering joint in Commercial Truck Use for?
- The steering joint in commercial truck use is responsible for connecting the steering box to the front wheels, allowing them to turn.
- It converts rotary motion from the steering box into linear motion, allowing commercial trucks to change direction. As commercial trucks tend to be heavy and oversized, this joint plays a critical role in maneuverability and driver safety.
- The commercial truck’s steering joint must be properly maintained throughout its lifespan to ensure that it functions correctly and does not fail during operation.
- Commercial trucks will not have complete control over their maneuvering capabilities without proper maintenance, leading to an increased risk of collisions or other accidents.
- Therefore, qualified professionals specializing in commercial vehicle repair services should carry regular maintenance for commercial truck steering joints.
- By ensuring that your commercial truck’s steering joint is kept in top condition, you can maintain the optimal performance and safety of your commercial truck.
What Parts Make Up the Steering Joint?
The following are joint steering components and the materials typically used for each element.
01. Spline yoke – Usually, the head bore has splines to connect other parts; this yoke is forged or casting, and the material is 45#.
02. Universal joint – It is one of the essential parts of the steering joint. It provides a flexible mechanical connection between two parts, allowing them to move around each other while transmitting torque. This connection creates a more efficient and reliable power transfer over an extended distance than traditional rigid methods.
- The body material is 20Cr; roughs are usually forged or cold extruded.
- The needle-bearing material is GCr15.
- The bearing cup material is 20#.
- The grease seal material is NBR.
- The snap spring material is 65Mn.
What are the Technical Standards for Each Component?
Commercial trucks generally carry heavy loads, requiring high-performance standards for each component. The following are the technical requirement standards for each commercial truck steering joint component.
01. Spline yoke – The torque requirement is 300 Nm, so it has high requirements for the rough, which has to be forged, followed by the cast. Our yoke torque can generally reach over 500 Nm.
02. Universal joint clearance – Universal joint clearance requirement is less than 0.03-0.05mm. Our universal joints are made of the “Wanxiang” brand, and the clearance is generally lower than 0.02mm.
03. Screws and nuts – Screws and nuts are also essential parts, screws require 10.9 class strength screws, and nuts require 8 class strength nuts. Screws and nuts require a torque of 120 Nm or more after locking. Our screws use class 10.9, and our nuts use class 8. The torque can generally reach 150 Nm or more after locking.
What Are The Types of Commercial Truck Steering Joints?
Because of the large load characteristics of commercial trucks and dump trucks, their steering joints require high torque and strength, which makes only forged roughs the most suitable, followed by cast roughs.
Forged Steel yoke
Forged yokes are the most widely used in automotive and truck steering shafts.
Because it has the highest material density, the best torque performance, is wear-resistant and durable, and is not easy to deform, this yoke will generally be used in middle and high-end passenger cars, SUVs, trucks, and agricultural machinery.
Casting Steel yoke
Casting yoke material density and performance can not be compared with forging yoke, but in the shape of the yoke, casting has more advantages than forging; casting can make a variety of shapes, not limited by the shape. But sometimes, the surface of the casted yoke will have air holes and sand holes.
So it is generally used for American cars, like Jeep, Ford, Lincoln, Dodge, Chevrolet, Buick, Cadillac, Chrysler, Hummer, GM, etc.
How Many Types of Surface Treatments for Steering Joint and Coupling?
Paint Spraying
Painting is the most common surface treatment for steering joints, as it is not limited by color and can be sprayed in various colors.
However, the surface adhesion of spray paint is not strong enough, and it is easy to scratch when encountering knocks. We add a baking process according to this characteristic, which can increase the adhesion of the spray paint surface, and can effectively solve this problem.
Electrophoresis
Electrodeposition is characterized by strong adhesion, a smooth and shiny surface, and not easy to scratch when bumped.
But it can only do black; no other color options.
And because the product needs to be over-acidic during the electrophoresis process, this leads to easy rusting inside the tube.
Neutral Color
Neutral color is not used much in the steering joint; although the product’s surface is coated with anti-rust oil before leaving the factory, the anti-rust time is not long.
Galvanized
The galvanized steering shaft is not used much. The surface is bright and beautiful, and the rust prevention is powerful.
How to See The Steering Joint Quality?
1. Check the appearance
Check the surface treatment for defects, bumps, or rust, then check the finish of the machined surface.
2. Check the burrs
Check the screw holes and keyways for uncleaned burrs, and this detail is something many small factories will overlook.
3. Check the universal joint
Check whether the universal joint oil seal has ruptured; the universal joint is one of the essential parts of the steering joint; if the oil seal ruptures, it will lead to the overflow of lubricating grease inside the bearing cup and the dirt and dust outside into the universal joint, which will lead to the life of the universal joint is significantly shortened.
4. Turning universal joint
Check whether the rotation is smooth; if there is a jam, the steering joint will have a strange sound in the process of use; feel whether there is a gap in the universal joint during the rotation Universal joint if there is a gap, the steering wheel will have a gap after the product is installed, which will affect the precision of the steering wheel rotation, resulting in increased driving danger.
5. Check the length
Measure the correct length of the product.
6. Check the dimensions
Measure the mounting position dimensions, including the diameter of the inner and outer spline, the number of teeth, the spline parameters, and the angle of the mounting position at both ends are correct.
7. Check the thread
Check if the thread specification is correct.
8. Check the spline
Use a thorough gauge to check if the spline parameters are correct.
9. Check other accessories
Check whether other accessories are complete, such as screws, nuts, gaskets, and other accessories.
What are the Most Common Problems that Occur with Steering Joints?
1. The universal joint quality is too poor to cause various problems.
For example, the universal joint clearance is too large, which causes the steering wheel to have a false position and is not sensitive.
The universal joint does not fit smoothly, and there is a snag in the rotation; this can lead to jerky and uneven steering.
Poor quality of the universal joint grease seal, resulting in grease leakage, will significantly reduce the service life of the steering shaft.
2. Spline parameter error.
For steering joints, spline parameters are critical. The product will not be installed and used if the spline is wrong.
What is our Solution?
For these problems, we offer the perfect solution.
1. We use the world’s best brand “Wanxiang” for universal joints, the best supplier globally.
