A universal wheel is what is known as a movable caster, which is constructed to allow for horizontal 360-degree rotation under dynamic or static loads. The design of a universal wheel allows a vehicle or piece of equipment to move in multiple directions without having to change its direction or turn.
A universal wheel usually consists of a center shaft and multiple support balls or beads. The center shaft can be mounted on the vehicle or equipment, while the support balls or support beads are arranged at regular intervals around the center shaft. The support balls or beads are usually connected to the center shaft by a device such as a bearing to ensure that the universal wheel can rotate smoothly.
When the universal wheel is subjected to an external force, the support ball or support bead can be rolled freely in more than one direction so that the vehicle or equipment can be moved in more than one direction. For example, when the vehicle or equipment needs to move to the left or right, it can simply turn the steering wheel or handle to the left or right. At this time, the universal wheel will rotate freely along the direction of the plane where the vehicle or equipment is located, thus realizing the movement of the vehicle or equipment.
Universal wheel it is widely used in a variety of vehicles and equipment, such as baby carriages, carts, flatbed trucks, etc., for their movement to provide convenience and flexibility.
For baby carriages or supermarket shopping carts and other light tools, the front and rear of the universal wheel does not have a great impact on the steering. The main factor that affects whether a universal wheel is front or rear mounted is the environment in which it is used.
There are several advantages to using a front mounted gimbal on a stroller: it is easy to cross obstacles, and the brakes are easy to operate. The front of the universal wheel, when encountering obstacles only need to step on the rear wheel axle, hand down a little pressure can be crossed, and there will be no universal wheel rear is generated by the phenomenon of instability. Then is the brake, baby stroller brake device is generally installed in the direction of the wheel, direction of the wheel in the back, parents brake only need to hold the push rod, with the foot gently step on the brake can be. If the universal wheel is rear-mounted, parents need to run to the front of the stroller when braking, which is very inconvenient.
For cargo-carrying flatbed trucks, the universal wheel is usually rear-mounted. Mainly because the rear-mounted universal wheel in the steering, you can get more steering torque, because at this time the steering can simply look at the car around the front wheel for the finger point of rotation, the force arm is longer. The use of cargo flatbed trucks in most cases is pulled, because the pulling of the field of vision is wide open, and more convenient to exert force. For cargo trolley no matter whether it is pushing or pulling, the force is best and the universal wheel in the same direction, so that it is easier to maneuver.
