All You Need to Know About Intermediate Steering Shaft
What is an Intermediate Steering Shaft?
- An Intermediate Steering Shaft (ISS) is a shaft that connects the steering gear to the steering column in vehicles with rack-and-pinion-type suspension systems.
- The ISS helps to ensure safe and consistent vehicle responsiveness. It also reduces vibrations, road noise, and harshness from transferring from the tires to the driver’s hands.
- In addition, an ISS holds all related parts together for a smoother and more efficient drive by allowing easy power transfer between components. When properly maintained, an ISS can help contribute to the better overall handling of a vehicle as well as improved safety.
- It’s essential to keep your Intermediate Steering Shaft in good condition through regular inspection and maintenance so it can continue performing optimally over time.
- Failure to do so could result in steering system issues, steering wheel vibrations, and other steering-related problems.
- Proper maintenance of your Intermediate Steering Shaft is essential for a safe and pleasant driving experience.
- 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 Intermediate Steering Shaft Use for?
- The Intermediate Steering Shaft is an essential component of steering systems. It connects the steering wheel to the steering column and transfers steering energy from one to the other.
- The steering shaft also serves as a bridge between the steering wheel and the steering box or rack-and-pinion unit, allowing for the smooth operation of the steering system.
- Additionally, it helps to reduce road vibration from reaching the driver by providing cushioning and dampening effects. This allowed for better control when driving and increased safety overall. Its features provide vehicle owners with improved performance and greater comfort while going.
- Overall, the Intermediate Steering Shaft plays an integral role in any car’s steering system, offering reliable performance that can help protect drivers and passengers.
- It is essential for steering systems to be well maintained, and replacing the steering shaft when necessary can help prolong the life of your vehicle. If you suspect that your steering system may need attention, it is essential to have it checked out by a qualified technician as soon as possible.
- Taking care of steering problems early on can save you time and money. So keep an eye on your steering components and promptly get any necessary repairs done.
What Parts Make Up the Intermediate Steering Shaft?
The following is a list of Toyota Camry intermediate steering shaft 45220-33190 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 stamped, and the material is 45#.
02. Universal joint – It is one of the essential parts of the intermediate steering shaft. 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 – Welded yoke bore splines are mated to the spline shaft and tube and welded together after a tight mating connection. This yoke is also stamped, and the material is 45#.
04. Rubber dust cover – The primary function is dust and noise insulation; usually, the material is 40Cr.
05. Spline tube – Spline tube with internal spline teeth to match the spline shaft. Usually, the material is 20#.
06. Spline shaft – Spline shaft connected to spline tube at one end and welded yoke at the other. The nylon used for the spline teeth is injection molded. Usually, the material is 40Cr.
There are four basic types of steering shafts. Splined shafts and “Double D” shafts are the most common. Some vehicles use a smooth post. Newer Ford vehicles use a V-shaped beam.
What Are The Types of Intermediate Steering Shafts?
Stamped Steel Yoke Intermediate Steering Shaft
Stamped yokes are generally used for small displacements of passenger cars like Hyundai, Kia, Renault, Fiat, Peugeot, and forklifts.
Because they have low torque requirements, and the products are simple in structure, light in weight, and low in cost.
Forged Steel Yoke Intermediate Steering Shaft
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 Intermediate Steering Shaft
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.
Extruded Steel Yoke Intermediate Steering Shaft
It is divided into two kinds of warm extrusion and cold extrusion; the surface of this kind of yoke is smooth, beautiful appearance, material density, and use performance are higher, so it now more and more popular.
These yokes are mainly used in small cars because their torque cannot be compared with forged and cast yokes.
Aluminum Intermediate Steering Shaft
The aluminum steering shaft is generally used more in German and tuned cars, think Mercedes-Benz, BMW, Volvo, etc..
It has lightweight, has a beautiful appearance, and has good performance.
Complex Structure of Intermediate Steering Shaft
- Intermediate steering shaft with two universal joints + length compensation.
- Intermediate steering shaft with two centered double joints + length compensation.
- Steering coupling with the corrugated tube.
- More piece I-shaft with top mount.
How Many Types of Surface Treatment for Upper Steering Shafts?
Paint Spraying
Painting is the most common surface treatment for steering shafts, 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 upper steering shaft; although the product’s surface is coated with anti-rust oil before leaving the factory, the anti-rust time is not long.
Zinc-nickel Alloy
Zinc-nickel alloy finish is rarely used on the steering shaft because of its high cost, but the color of the outer tube looks very advanced, and only Audi’s steering shaft is known to use this finish.
Phosphorization
The color after phosphating is the same as the neutral color; the only difference is that after doing the phosphating treatment, there will be a layer of anti-rust material on the product’s surface, which can greatly reduce the rusting of the product.
Galvanized
The galvanized steering shaft is not used much, currently only in the Land Rover useful for such products. The surface is bright and beautiful, and the rust prevention is powerful.
How to See The Upper Steering Shaft 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 intermediate steering shaft; 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 shaft 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 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 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 0.03mm, 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 length
Measure the correct length of the product, and for steering shafts with telescoping, measure the right length in tension and compression.
8. 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.
9. Check the welding
Check whether the weld is solid, there is no crack or false welding, and the upper steering shaft is a safety part; if welding problems, the use of safety accidents.
10. Check the rubber parts
Check whether the rubber parts are broken.
11. 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 Intermediate Steering Shafts?
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. The uneven coating of nylon on the teeth of the spline shaft will lead to too much clearance in the steering assembly, and the steering will have a false position and be unresponsive.
The steering shaft is a safety part, which are unstable factors that significantly affect 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. Regarding the nylon coating of the spline shaft, we use the injection molding process to make the nylon coating of each spline tooth uniform to achieve adequate control of clearance and smoothness of stretching, and more wear-resistant and not easy to fall off.
The difference can be easily seen from the appearance.
