All You Need to Know About Commercial Truck Steering Shaft Column
What is a Commercial Truck Steering Shaft Column?
- A commercial truck steering shaft column, also named steering column shaft, is a component of commercial trucks that transfers the steering wheel’s movement to the steering gearbox.
- It transmits rotational torque from the driver input and makes it possible for the vehicle to turn left or right, as desired.
- The commercial truck steering shaft column consists of several components: a spline tube, a spline shaft, two spline yokes, two weld yokes, universal joints, and bearing assemblies.
- Furthermore, it is engineered with safety features such as tilt-away designs that enable easier access for service or repairs.
- In summary, commercial truck steering shaft columns are essential parts in commercial trucks to ensure proper control and safe operation on the roads.
What does the Steering Shaft Column in Commercial Truck Use for?
- The Steering Shaft Column in commercial trucks is an essential component of the steering system used to provide efficient and effective steering capabilities.
- It is a conduit between the steering wheel and the other parts of the truck’s steering assembly, allowing for smooth movement and precise control.
- The Steering Shaft Column connects to components such as the Pitman Arm, center link, idler arm, drag link, tie rod ends, and power steering pump.
- Its primary purpose is to transfer rotational force from the steering wheel to these various components so that they can effectively perform their respective duties in turning or maneuvering commercial trucks.
- Commercial truck drivers would struggle with properly controlling their vehicles without a functioning Steering Shaft Column.
- Therefore, it is essential for commercial truck operators to regularly inspect and maintain their steering shaft columns to ensure optimal steering performance.
What Parts Make Up the Steering Shaft Column?
The following are commercial truck steering shaft column 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 cast, and the material is 45#.
02. Universal joint – It is one of the essential parts of the steering column. 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.
03. Weld yoke – This yoke is forged or cast; it will weld on the spline shaft and the spline tube. The material is 45#.
04. Spline shaft – Usually, the shaft material is 40Cr, and the blue nylon coating material is PA11 coating grade.
05. Dust cover – Its function is to prevent mud and dirt from entering the inside of the spline tube. The material is NBR.
06. Grease nozzle – The material is stainless Steel.
07. Spline tube – The spline tube consists of 2 parts, the part connected to the spline shaft is made of 40Cr, and the tube has spline teeth inside to match the spline shaft. The part connected to the welded fork is made of 20# and has no internal spline teeth. The two sections are joined by welding.
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.
04. Spline shaft and tube clearance – The standard clearance between the spline shaft and tube should be less than 0.05mm; our products’ clearance is generally less than 0.03mm.
What Are The Types of Commercial Truck Steering Shaft Columns?
The following is a classification of commercial vehicle steering shaft columns according to the type of spline shaft.
Four teeth shaft with nylon-coated internal tube teeth without nylon coating.
Four-tooth shaft, no nylon coating, tube internal teeth with nylon coating.
Multi-tooth shaft, no nylon coating. Tube internal teeth with nylon coating.
Long multi-tooth shaft without nylon coating. Tube internal tooth with nylon coating.
Original spline structure, six-tooth shaft with ball bearings, six-tooth matching inside the tube.
01. The number of teeth inside the tube is the same as the number of teeth of the matching spline shaft.
02. If the spline shaft has nylon coating, there is no nylon coating inside the tube. If the spline shaft does not have nylon coating, there will be nylon coating inside the tube.
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.
How to See The Steering Shaft Column 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 grease seal has ruptured; the universal joint is one of the essential parts of the steering shaft column; if the grease 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 telescoping function
With the telescopic steering shaft column to do axial stretching to see whether the expansion and contraction are smooth, if the extension has a jam, it will affect the product’s performance after installation.
6. Check the clearance
The steering shaft column with telescoping also has to do the lateral clearance test; the spline shaft and shaft tube will be twisted backward by hand to see if there is a gap. Average clearance needs to be less than 0.05mm, such as too much clearance, the product will have a strange noise after installation and will affect the precision of the steering wheel rotation.
7. Check the nylon coating
Nylon coating is an essential component in controlling the clearance of the steering shaft column assembly, and it increases the wear and corrosion resistance of the shaft. Check to see if the coating is even and firm and if there are any damaged areas.
8. Check the length
Measure the correct size of the product, and for the steering shaft column with telescoping, measure the right size in tension and compression.
9. 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.
10. Check the welding
Check whether the weld is solid, there is no crack or false welding, and the steering shaft column is a safety part; if welding problems, the use of safety accidents.
11. Check the rubber parts
Check whether the rubber parts are broken.
12. 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 Shaft Columns?
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 column.
2. Spline parameter error.
For steering shaft columns, spline parameters are critical. The product will not be installed and used if the spline is wrong.
3. Poor quality nylon coating
Nylon coating is an essential component in controlling the clearance of the steering shaft column assembly, and it increases the wear and corrosion resistance of the shaft.
Poor quality nylon coating can seriously affect the steering shaft’s quality and significantly impact driver safety.
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.
The gap in the universal joint, jamming, and grease seal leakage can be avoided entirely.
2. To address the problem that spline parameters are prone to errors, we have made unique spline through gauges for each spline specification and bore. Make sure every spline is thoroughly inspected to avoid any wrong product in your hand.
3. We have changed the nylon coating over-molding process to an injection molding process, which makes the nylon coating thickness of each tooth uniform and beautiful.
And we use imported nylon plastic powder coating grade PA11, plus the special nylon primer, which makes the nylon coating not easy to fall off and more wear-resistant corrosion resistance.
It is possible to effectively control the mating clearance between the shaft and the tube to less than 0.05mm.
4. We have developed the same spline shaft process as the original parts, six tooth shaft with ball bearings; this process is more stable and durable and can control the fit clearance between the shaft and the tube to less than 0.03mm.
