Why are wheelchair wheels angled?

Wheelchair wheels are angled to improve maneuverability and stability. The angle offsets the load and widens the wheelchair’s base, which makes turning easier and makes it less likely the wheelchair will tip over when doing sharp turns or when you’re on a slope.

Wheelchairs are an essential means of mobility for millions of people around the world. Part of a wheelchair’s design is to with the angle or camber of the wheels. Have you ever wondered why wheelchair wheels are angled? What purpose does it serve? In the rest of this piece I’ll delve into the mechanics and reasoning behind angled wheelchair wheels. I’ll discover how the camber angle affects the wheelchair’s performance and the practical advantages it offers when you deal with various terrains and environments.

So, let’s unravel the mystery behind why wheelchair wheels are angled, and discover the remarkable impact the design choice has on the lives of wheelchair users everywhere.

What does camber mean on a wheelchair?

Camber, when talking about a wheelchair, refers to the tilt or angle at which the wheels are set. It’s a design feature where the top of the wheel is positioned wider apart than the bottom. This angle creates a V-shape when seen from the front or back of the wheelchair. The camber improves the stability, maneuverability, and overall performance of the wheelchair. By tilting the wheels, the wheelchair’s balance is improved, there is a better weight distribution, and increased traction, allowing for smoother navigation and giving you more control.

What is the point of cambered wheels?

Cambered wheels have several purposes, not least as integral to wheelchair design. The point of having cambered wheels is:

• To improve stability – The angled position of the wheels provides a wider base of support, making the wheelchair more stable. This helps prevent tipping or toppling over, especially when you turn sharply or go over uneven ground.
• For better maneuverability – Cambered wheels make it easier to move the wheelchair because the overall turning radius is decreased. The angled wheels allow for easier and tighter turns, making it easier to navigate through narrow spaces and crowds.
• Better weight distribution – The camber angle offsets the vertical load placed on the wheels when you sit in the wheelchair. This means you’re more balanced, ensuring more comfort for whoever is using the wheelchair.
• To make propelling the wheelchair more efficient – Cambered wheels minimize the contact the wheel patch area has with the ground, which reduces resistance. This means users can move the wheelchair with less effort than if the wheels weren’t angled.
• Better traction – Angled wheels help improve grip and traction. When you’re on slippery ground or outdoors, it makes for a more secure and safe experience.

The point of having cambered wheels then, is to maximize stability, efficiency, traction, safety, and maneuverability for wheelchair users.

Later, I’ll find out how you can adjust the camber on a wheelchair. Right now, though, let’s go through the disadvantages of having cambered wheels.

What are the disadvantages of cambered wheels?

It’s worth noting that there are disadvantages to cambered wheels too.

• They increase the width of the wheelchair – Having cambered wheels can make a wheelchair wider, which may make it trickier to navigate narrow doorways and tight spaces.
• They increase the wheelchair’s weight – This may affect the maneuverability of the chair, depending on the amount of weight added and the additional materials needed.
• The wheelchair may be less stable when moving in a straight line – The angle of the camber may make the wheelchair a little less stable when you’re going straight at high speeds.
• More resistance on flat surfaces – If you have cambered wheels, you’re more likely to experience marginally higher resistance on flat services than you would if the wheel weren’t angled.
• The wheelchair will need alignment adjustments and frequent maintenance – You must ensure you make regular adjustments to the wheels to ensure they are properly aligned. If the wheels aren’t aligned properly, it can affect maneuverability, performance, and stability.

Given these drawbacks, it’s vital to consider your specific personal needs and preferences when deciding if you need cambered wheels or not. Ask yourself what you will use the wheelchair for, and in what situations you’re likely to find yourself.  

If you’re unsure whether cambered wheels are necessary, you may want to seek advice from wheelchair specialists or a healthcare professional. Wheelchair specialists can also help you check the alignment of your wheels periodically so you can keep everything in good condition.

It’s time to find out how to adjust the camber.

How do you adjust the camber on a wheelchair?

There are several steps you must take to adjust the camber on a wheelchair, as it normally also entails altering the wheel alignment.

To do so, take the following steps:

• Find the alignment points on the wheelchair frame. You can usually locate these near the axle, or the wheel attachment points.
• Loosen fasteners that secure the wheel to the frame such as screws and bolts, so you can adjust them.
• Change the camber angle. This is usually done by rotating the acle using adjustable camber plates, however, exactly how you do this will depend on the wheelchair’s make and model. Refer to the instruction manual if you’re unsure how to do it.
• Make sure everything is symmetrical. You must change the camber angle evenly on both sides of the wheelchair, so the wheelchair remains balanced and stable.
• Tighten the fasteners using the correct tool, whether that be a screwdriver or wrench.
• Check the alignment to ensure they are straight and parallel to each other because the wheels being misaligned could affect the way the wheelchair performs.

If, at any point, you’re unsure about this process, it’s best to seek advice from a wheelchair specialist, or the wheelchair manufacturer’s support team. They can give you the guidance you need.

Cambered wheels maximize stability, efficiency, traction, safety, and maneuverability

Do wheelchair wheels go flat?

Wheelchair wheels can go flat, like other pneumatic tires. Pneumatic wheelchair tires are filled with air, so are subject to punctures or leaks that cause them to lose air pressure.

This can result in a flat or partially deflated tire. Flat tires can affect the wheelchair’s performance, maneuverability, and comfort. Regular maintenance, such as checking tire pressure and addressing any leaks or punctures, is essential to make sure that the wheels are properly inflated and functional.

Some wheelchairs also have solid or foam-filled tires that aren’t filled with air and are therefore not as prone to going flat.

Summary: Why are wheelchair wheels angled?

Wheelchair wheels are angled, to offer users benefits that enhance stability, maneuverability, weight distribution, efficiency, and traction. This thoughtful design choice makes it easier for wheelchair users to navigate their surroundings with confidence and ease, improving accessibility and quality of life. The cambered wheels exemplify the commitment to innovation and continuous improvement in mobility solutions for disabled people.
