Wheel Axle Cover

January 24, 2023 by No Comments


A wheel axle cover is a covering device that surrounds a wheel axle in the form of a circular-cylindrical pipe. It is preferably used on rail-mounted vehicles. Wheel Caps The wheel axle is also protected against flying stones. As a result, the axle cover can increase the fuel economy of the truck and improve aerodynamics. In addition, a wheel axle cover can be installed in a matter of minutes.

The axle covers are made of cross-linked polyethylene. This material has improved properties and can withstand high temperatures. They are also resistant to rust formation. These covers are easy to install and can be replaced with a prybar or even hand-tightened. Depending on the type of materials used, the covers can be made from black, chrome, or polished chrome.

The wheel axle covers have circumferential ridges. Each ridge is parallel to the rotation axis of the axle. Ridges have a plane top surface and a plane bottom surface. Their height is approximately 30-50% of the height of the bottom surface. When the ridges are placed on the axle, they abut against the rustproof surface of the axle and form an air channel between them. Air is pressed out radially and is transported away from the axle. Similarly, moisture is pushed out axially and is transported away from the axle.

The ridges of the axle cover can be arranged in a number of ways. Some of the ridges are straight. Others are angled, while others may have an angle of 45deg-90deg. One of the ridges may be abutted against the rustproof surface of the axle while the other abuts against the inner layer of the axle.

Another way of arranging the ridges is to provide them with an axially directed cross channel. When the ridges are assembled, they abut against the corresponding edge surfaces of the second axle cover part. Alternatively, radial gaps are provided between the ridges. Besides, a gap is created between the two axle covers to allow air to be pressed out radially from each cover.

Other features of the axle cover are the elevations between the two parts and the ridges. The elevations help to guide the strip clamps when the axle cover is mounted on the wheel axle. Also, they contribute to the drainage of water. Besides, a ridge can be angled in order to increase the air speed in the air channel. Moreover, the distance between the ridges may be constant or tapered for each axle cover part.

For a rail-mounted vehicle, a width of 2mm is recommended for the top surface of the ridges. The ridges are preferably coated with a two-component epoxy lacquer. However, a top surface that is too narrow indicates that wear is likely to occur and too thick implies that too much load is distributed.

Wheel axle covers can be made from cross-linked polyethylene, which has improved properties and a better temperature range. Alternatively, they can be made from steel or aluminum. An axle cover can be easily mounted with basic tools.
