The big wheel of the power wheelchair is the driving wheel, the small wheel is the guiding wheel, whether the big wheel is in the front or the back, it is decided that the driving method of the power wheelchair, the big wheel in the front if the obstacle performance is better, and the big wheel is in the back is smoother and more comfortable, how to choose mainly depends on the road that the power wheelchair is often traveling. When choosing tires for power wheelchairs, there are two kinds of tires: solid tires and hollow tires, so is it good to have solid tires for power wheelchairs? Is it better to have solid or inflatable tires for power wheelchairs? Here together to understand it.
1.Power wheelchair big wheels in the front and in the back which is better
The tires of the electric wheelchair are usually four, a pair of big pairs or small pairs, some electric wheelchairs have big wheels in the back, some are big wheels in the front, so the electric wheelchair has big wheels in the front of the good or big wheels in the back of the good?
The power wheelchair has big wheels in the front the back the difference is mainly front-wheel drive or rear-wheel drive, the big wheel is the driving wheel, and the small wheel is the guiding wheel, front-wheel drive power wheelchair has the big wheels in the front, and vice versa, the big wheels in the back of the rear-wheel drive, the two drive mode of power wheelchair each has its advantages and disadvantages:
1.1 The advantages and disadvantages of front wheel drive power wheelchair
(1) Advantages: Font wheel drive power wheelchair have better barrier-crossing performance, due to the larger diameter of the driving wheel in front, across the higher ditch, and small canter than the rear wheel drive power wheelchair.
(2) Disadvantages: the turning radius is larger, and the rider will feel a kind of forward-leaning feeling when going downhill.(In the specified slope range regardless of what drive form of the regular manufacturers of power wheelchairs are safe, because to solve the power wheelchair uphill and downhill safety hazards, production will be rigorous safety testing.
1.2 The advantages and disadvantages of rear-wheel drive power wheelchairs
(1) Advantages: rear-wheel-drive power wheelchairs are smoother, more comfortable, and more flexible in steering.
(2) Disadvantages: It is easy to throw off the tail on the ice and snow road.
When shopping for a power wheelchair, choose the big wheels in the front or the big wheels in the back available, mainly depending on the user who usually sits in the power wheelchair road conditions.I recommend the electric wheelchair with small front wheels. it is affordable and cost-effective.
2. Power wheelchair solid tires and pneumatic tires which is better
When you buy a power wheelchair, the tires of the power wheelchair are also a more important reference factor, generally, the tires of the power wheelchair have two kinds of solid tires and pneumatic tires, so which kind of tires of the power wheelchair are good?
2.1 Solid tire
(1) Advantages: not afraid of tire puncture, easy maintenance, more economical.
(2) Disadvantages: solid wheel in the flat ground to go faster and not easy to burst, easy to push, but in the potholes on the road, vibration, and stuck in the same width as the tire in the ditch is not easy to pull out.
2.2 Pneumatic tire
(1) Pneumatic wheels have good elasticity, and the feeling of bumps is weaker when traveling on potholes, and pneumatic wheels are lighter.Heavy duty electric wheelchair often have pneumatic tires.
(2) Disadvantages: fear of puncture, the need for frequent inflation and tire repair, long time need to change the inner or outer tires; the inflatable inner tube is more difficult to push, but also easy to puncture, but vibration is smaller than solid; tubeless inflatable type due to the lack of inner tube will not be punctured, and the internal also inflatable, comfortable to sit up, but more than the solid tires are difficult to push.
In general, for electric wheelchairs, the tires are smaller, certainly, solid tires are more practical, and not afraid of zapping; tires are larger, and the inflatable wheels are more convenient, lightweight, and good flexibility. Individuals also have small wheels with pneumatic tires or large wheels with solid tires, this will need to be chosen according to preference. For example, there is no requirement for weight, then the big wheels with solid wheels also save trouble, in turn, the elasticity of the requirements of particularly high, then the small wheels also choose pneumatic wheels.
