Description

Technical Field

[0001] The utility model relates to the technical field of driving wheels, and more specifically, to a crawler driving wheel. Background Art

[0002] The crawler driving wheel is powered by an electric motor or a hydraulic system, converts electrical energy or hydraulic energy into mechanical energy, and pushes a crawler robot or vehicle forward. The driving wheel can adjust the speed as needed to achieve precise control of the movement of the robot or vehicle to adapt to different working scenarios and task requirements.

[0003] After retrieval in the existing publicly disclosed technical literature, the patent with the Chinese patent publication number CN111994180A discloses a driving wheel for a crawler vehicle. This driving wheel mainly realizes the co-driving of the crawler by the driving teeth and friction force, which is beneficial to reducing the load of the driving teeth and prolonging the service life of the crawler system. Through the design of the first reinforcing rib and the second reinforcing rib, the structural strength of the driving wheel is enhanced, and the situation of the driving wheel being damaged and broken is avoided. The elastic force of the spring pushes the locking rod and the locking head, thereby realizing the clamping connection between the locking head and the driving shaft, which is beneficial to the stability of the installation of the driving wheel. However, this driving wheel has the following defects;

During the rotation process, it mainly rotates in contact with the driving shaft through the internal driving hole. The contact rotation power is large, and it is difficult to disperse the central driving force, which will easily cause the driving hole to be worn and the durability is poor. This requires a crawler driving wheel. Summary of the Utility Model
