Universal wheel with direction induction mechanism

Abstract

The invention provides a universal wheel with a direction induction mechanism. The universal wheel comprises a universal wheel body. The universal wheel body comprises a wheel unit, a wheel axle and a universal wheel pendulum shaft. The wheel unit is connected with the wheel axle through bearings, and the wheel axle is fixedly connected with the lower end of the universal wheel pendulum shaft. The induction mechanism is arranged on the upper portion of the universal wheel pendulum shaft and rotatably connected with the upper end of the universal wheel pendulum shaft. The induction mechanism is fixedly connected with an external power source, and driven by the external power source to drive the universal wheel pendulum shaft to rotate, and accordingly the universal wheel pendulum shaft is always located in front of the wheel unit in the advancing direction of the wheel unit. By mounting the induction mechanism capable of driving the universal wheel pendulum shaft to rotate at the upper end of the universal wheel pendulum shaft, it is guaranteed that the universal wheel pendulum shaft is always located in front of the wheel unit in the advancing direction of the wheel unit, the phenomenon that the universal wheel body gets stuck when naturally turning is effectively avoided, it is ensured that large pendulation of the universal wheel body during operation is avoided, a plurality of sets of universal wheels can be applied to large mechanical equipment, a motion control system is simplified, and the reliability and stability of motion of large machines are improved.

Description

technical field [0001] The invention belongs to the technical field of sports machinery, and in particular relates to a universal wheel with a direction inducing mechanism. Background technique [0002] The universal wheel is a very common mechanical mechanism. Due to its simplicity and flexibility, it can be seen in many places such as suitcases and trolleys. The universal wheels on suitcases and trolleys, People generally don't pay attention to the phenomenon that the universal wheel may be stuck instantly when it suddenly turns to retrograde. problems, and even damage to parts; careful analysis is not difficult to find that the wheel is always behind the universal shaft when the universal wheel moves normally. Make 180 ° rotation, just can carry out normal movement. In the process of realizing this steering, the universal wheel will make its carrier laterally displace. For a system with only one universal wheel, this short-term lateral movement will not have much impac...

AI Technical Summary

Problems solved by technology

For a system with only one universal wheel, this short-term lateral movement will not have much impact on the movement of the system, but for a system with more than two universal wheels, if the universal wheel deflects If the direction is inconsistent, there will be a stuck phenomenon

Suitcases pulled by people often get stuck, but as long as they are pulled hard or sideways, they will cross the dead point. As for mechanical equipment, due to the limited power of the configuration, if there is a stuck phenomenon, it is difficult to get over. The above problems need to be improved
