Recently, two piece forged wheels are more and more popular in daily life. A two piece wheel have rims fabricated separately from the center and then fastened together with bolts. It is convenient to use a complicated finish since the barrel and the center are separated. The shape is also more complicated and changeable, more fashionable. Besides, through the different sizes of rims and spokes, it is possible to match the specifications of a variety of hubs to meet the needs of customers.

DH wheel is the forged wheels manufacturer which can custom made for customer to fit their requirements.We could show yousome types of 2-piece forged wheels.

All the 2 piece wheels can be custom made 18-22 inch,andthe wheels size and color can be customized.

From the perspective of vehicle performance and driving experience, they can indeed have different effects. Usually, large wheels usually have a more domineering appearance, making the entire body appear more calm and powerful. At the same time, large wheels can also improve driving stability and reduce the tilt of the vehicle when turning, thereby enhancing handling and safety.

In addition, large wheels can also improve the load capacity and grip performance of the vehicle. When the tire size is larger, the flattening rate of the tire is relatively small, which means that the contact area between the tire and the road surface is larger and the friction force is greater. This is particularly important for high-speed driving and curve driving, because it will make the vehicle more stable and provide stronger support.

But it is worth noting that the big wheels are not perfect. Large wheels will affect the acceleration and braking performance of the vehicle, because the weight and resistance of the wheels will increase. And large wheels are usually noisier than small wheels, which means they produce more tire noise and affect ride comfort.

Therefore, when choosing the size of an automobile hub, it is necessary to balance the needs of various aspects and weigh different advantages and disadvantages. And according to the adaptability of the model, choose the appropriate size of the wheels to ensure the stability and comfort of the vehicle.

Forged wheels are a premium choice for those seeking high performance, durability,lighter,and aesthetic appeal in their vehicles. Unlike cast wheels, which are made by pouring molten metal into molds, forged wheels are created by applying intense pressure to a solid piece of metal, usually aluminum or aluminum alloys.

1.Lightweight and Performance Benefits
One of the main advantages of forged wheels is their lightweight design. The forging process eliminates internal air pockets, creating a denser, stronger structure. This reduces the overall weight of the wheel, which improves vehicle performance in several ways. Lighter wheels reduce the rotational mass, leading to better acceleration, quicker braking, and enhanced handling.

2.Increased Strength and Durability
Forged wheels are significantly stronger than cast wheels due to their solid, uniform structure. The forging process aligns the metal’s grain, enhancing its strength and resistance to deformation. This makes forged wheels moreimpact-resistant andless likely to crack or warp under pressure. This strength is especially important in high-stress conditions, such as racing or driving on rough roads. Forged wheels are better equipped to withstand potholes, curbs, and heavy braking, offering longer-lasting performance and greater safety.

3.Aestheticand Customization
Another key advantage of forged wheels is theiraesthetic flexibility. The forging process allows for more intricate designs and finer detailing, which makes it easier to create wheels with custom shapes and finishes.

4.Long-Term Cost Effectiveness
While forged wheels come at a higher upfront cost, they offer better value over time. Their superior strength and durability mean they are less likely to need replacement due to cracking or wear. Additionally, their ability to reduce weight and improve vehicle performance may result in long-term savings on fuel or battery life in electric vehicles. For those who prioritize quality and longevity, forged wheels are a worthwhile investment.

In summary, forged wheels offer significant advantages in terms of lightweight design, strength, durability, and performance. Their ability to withstand high-impact stresses, improve handling, and dissipate heat makes them ideal for high-performance and luxury vehicles.

When it comes to wheels, the termssize,PCD,ET, andCB refer to important specifications that ensure proper fitment and performance on a vehicle. Here's a breakdown of each term:

1.Size of the Wheel

The size of a wheel typically refers to two key measurements:diameter andwidth.

Diameter: The overall diameter of the wheel, usually measured in inches. Common sizes include 15-inch, 16-inch, 17-inch, 18-inch, and so on. This measurement corresponds to the distance from one end of the wheel to the other, from edge to edge.

Width: The width of the wheel is also measured in inches and refers to the distance between the inside edges of the wheel's rim, where the tire sits. For example, you might see a wheel labeled as 18x8.5, which means the wheel has an 18-inch diameter and an 8.5-inch width.

Example: A wheel size of 18x8.5 means:

· 18 inches in diameter

· 8.5 inches in width

2.PCD (Pitch Circle Diameter)

· Definition: PCD refers to thediameter of the circle formed by the centers of the wheel’s bolt holes.

· Format: It's represented by two numbers: the number of bolt holes (studs) and the diameter of the circle (in mm). For example,5x114.3 means:

o 5 bolt holes

o 114.3 mm diameter of the circle passing through the center of the bolt holes.

Example:5x114.3 means:

· 5 bolt holes

· A bolt circle diameter of 114.3 mm

3.ET (Offset)

· Definition: ET, oroffset, is the distance from the wheel’s mounting face (the part that contacts the hub) to the wheel’s centerline.

· Types:

o Positive Offset (ET +): The mounting face is towards the front (towards the wheel's outer side), pushing the wheel inward.

o Negative Offset (ET -): The mounting face is towards the back, pushing the wheel outward.

o Zero Offset (ET 0): The mounting face is aligned with the centerline of the wheel.

Example:ET40 means:

· The mounting face is 40 mm towards the outside of the wheel centerline.

4.CB (Center Bore)

Definition: Thecenter bore is the diameter of the hole in the middle of the wheel, which fits over the hub of the vehicle. It’s crucial for the wheel to match the hub size to ensure the wheel is properly centered.

Common Sizes: Center bore sizes vary based on the vehicle make and model. For instance, common center bore sizes are56.1 mm,66.1 mm, or70.3 mm.

Example:CB 66.1 means:

· The center bore is 66.1 mm in diameter.

The wheel rim is an important part of the car, also known as the rim.Generally speaking, it is the part of the axle mounted in the center of the wheel.

Automobile wheels are mainly divided into manufacturing processes, namely casting and forging.Generally speaking, the cast ring is aluminum, and the forged ring also has aluminum and titanium.However, in general, forged rings have high strength, cast rings are light in weight, automobile power loss is small, and the running speed is fast.

Another different indicator of the wheel rim is the different hole distance and eccentricity distance.The hole distance is just the position of the screw.The eccentricity distance reflects the distance of therim from the surface of the screw to the centerline of therim.A very good wheel rim requires uniform density, round shape, and good performance.

Car wheels can be updated, and some people will upgrade their wheels.For larger wheels, the outer diameter of the tire remains the same, and the flatness of the tire becomes larger.The lateral swing of the car is smaller and the stability is improved.However, the car has lost its comfort.The wheels currently used are made of aluminum alloy material, which has a beautiful appearance, but they are also very exquisite. In order to maintain the beauty of the wheels, in addition to paying special attention to preventing accidental damage to the wheels during driving, regular maintenance of the wheels is also required.

When choosing the size of a car wheel, there are many factors to consider.Traditionally, larger wheels are considered a better choice because they can provide a better appearance and higher performance.However, not all vehicles are suitable for using large-size wheels, so different factors need to be weighed.

First, larger wheels usually mean smaller tire flatness.This can improve handling and vehicle response, but it may also affect ride comfort.A smaller flatness of the tire may make the tire more susceptible to damage on uneven roads, which may increase the maintenance cost of the vehicle.

Secondly, larger wheels can improve the performance of the vehicle.This is because larger wheels can provide more brake space and lower rotational inertia.These factors can improve braking ability and acceleration performance, but the correct size must be selected to ensure good results.

Finally, larger wheels may have an impact on fuel economy.This is because larger wheels usually mean greater wheel weight and higher rolling resistance of the vehicle.This may lead to a decrease in fuel economy and increase the operating costs of the vehicle.

Considering these factors, the size of the wheel hub varies from car to car.

Generally speaking, smaller cars are suitable for using smaller wheels, while larger SUVs and trucks are suitable for using larger wheels.

In addition, the usage scenarios and personal preferences of the vehicle need to be considered.

When purchasing a new wheel, you should consult a professional automotive technician to ensure that the appropriate wheel size is selected.

“Multi-layer environmental protection ion technology" uses powder spraying technology and magnetic control vacuum coating technology to process electroplating wheels. The production technology replaces the traditional high-pollution, high-cost, zero-pollution, and production model, creating high value-added, advanced product technology, beautiful and luxurious appearance, green environmental protection, and superior performance. It has been widely recognized by the domestic and foreign markets.

Once the electroplated wheel rim is scratched, the cost of replacing the entire wheel rim is relatively high, and it is not affordable, and it cannot be repaired and refurbished.

Generally, some of the original wheels have a painted surface, some have a brushed surface, some have a polished surface, some are imitated electroplating, and some are electroplated wheels.

Then, whether it is painting, drawing, polishing, or electroplating, it can be changed to electroplating wheels.If the surface is electroplated wheels, it can be electroplated after a long time.

Some car owners may question that it is not difficult to change the wheel technology, but if our wheel itself has corrosion, clearance, deformation, etc., can we still electroplate it?

It's completely possible. The electroplating of the wheel rim is to repair the wheel rim and then electroplate it to ensure the quality and effect of the wheel rim electroplating for most car owners.

After the wheel rim enters the factory, it will be handed over to a professional wheel rim maintenance expert for wheel rim inspection to confirm whether the wheel rim has corrosion, gaps, deformation, fracture, etc.If so, after the wheel rim repair is completed, professional electroplating equipment and electroplating technology will be used for electroplating and electroplating.At the same time, combined with professional maintenance technology, new maintenance effects can be achieved, the surface is smooth and bright as a mirror.

The vast majority of aluminum alloy automobile wheels are now cast, despite the heat treatment, the residual stress must still exist. If it is an even number, it is easy to produce greater stress on a pair of spokes at 180 degrees, which exceeds the tensile and shear strength, and then breaks. If it is an odd number of spokes, the stress and deformation can be transferred to more spokes, which plays an average role. If the three frames are too far apart, the force is still concentrated, and the five spokes are ideal. Also because of this reason, the ten-spoke wheels are generally arranged in a double five-spoke manner.

1. What is a car seat slide?

The slide is an important mechanical component on the seat. The common slide is mainly installed under the seat and is used to adjust the front, back, left and right positions. It usually consists of two parallel tracks and a sliding mechanism. By operating the adjustment handle or button on the seat, the seat can move smoothly forward and backward on the slide to meet the riding needs of different drivers and passengers.

The slide is generally composed of upper rails, lower rails, locking mechanisms (manual), adjustment mechanisms (electric), ball rollers and ball roller cages.

 

 

 

2. The role of the slide

（1）Adjust the position of the seat to facilitate the driver to adjust to the appropriate position and control the car; or to allow passengers to get a more comfortable space.

 

 

（2） Ensure the strength and rigidity of the connection between the seat and the base plate, so that the seat can maintain the sitting posture when the car is hit, increasing safety.

 

 

3. Classification of slides

3.1 According to the drive:

① Manual slide: You need to pull the towelbar to unlock the slide, and then push the seat to slide. According to the position of the unlocking handle, it is further divided into built-in unlocking manual slides and external unlocking manual slides.

 

 

 

② Electric slide rail: The slide rail that automatically adjusts the front and rear of the seat is driven by a motor. According to the different positions of the motor, it is further divided into a central electric slide rail and a front electric slide rail.

 

 

3.2 According to the stroke:

① Ordinary slide rail: A slide rail with a shorter adjustment stroke, generally about 180mm-260mm.

 

 

② Long slide rail: Adjust to form a longer slide rail, with a stroke of about 400mm-1500mm.

 

 

3.3 According to the adjustment direction

① Longitudinal slide rail: The most commonly used slide rail, the slide rail that the seat can move in the longitudinal direction.

 

 

② Horizontal slide rail: The slide rail that the seat can move in the horizontal direction is mostly used in some MPVs (Odyssey, Elysion, etc.).

 

 

③ V-type slide rail: The slide rail that the seat moves at a certain angle along the longitudinal direction in the car, and this slide rail is less used.

 

 

3.4 According to the rail type

① W-type rail (M-type): The cross-section of the slide rail is a W-shaped slide rail.

W-type slide rail takes into account cost, process and performance, and is currently the most widely used slide rail.

 

 

②C-type rail: The cross section of the slide rail is a C-shaped slide rail.

 

 

③T-type rail: The cross section of the slide rail is a T-shaped slide rail.

 

 

④High-low rail: The cross section of the slide rail is a slide rail with one side high and one side low.

High-low rail has the characteristics of good peeling strength, high lateral stiffness, and good synchronization, but its manufacturing process is more complicated than that of W-type slide rail and the cost is higher. It is currently used in some high-end models.

 

 

4. Slide rail performance

The main performance of the slide rail includes peeling strength, locking strength, unlocking force, free clearance, etc.
