Application of Climbing Wheel in Stair Climbing Wheelchair

A stair-climbing wheelchair refers to a special wheelchair that can assist people with reduced mobility to go up and down stairs. General wheelchairs can only walk on flat ground. For some people who need to go upstairs without elevators and cannot move their legs and feet normally, they need to climb stairs wheelchairs. The two groups of larger wheels in the front of the Climbing Wheel have bearings on the surface of the wheel body, followed by a pair of small wheels; the wheels in the rear have no bearings; above the wheels, there are several groups of seemingly complicated drive shafts , Some of these drive shaft sets are connected with the two sets of wheels below, and some are connected with the chair on the top; in front of the wheelchair chair, there are two joysticks similar to the transmission of the car.
