Protective cooling device for hub motor

Abstract

One or more embodiments of the invention provide a protective cooling device for a hub motor, which comprises a hub, wherein an inner ring coaxially arranged in the hub, a plurality of fixing frames are fixedly connected between the inner ring and the outer ring of the hub along the radial direction, a plurality of blades are arranged on the inner ring of the front side of the hub along the radial direction, a connecting frame is arranged at the upper end of the outer side of the hub, an annular frame is fixed on the connecting frame, a circulating cylinder is coaxially arranged in the inner ring in a penetrating mode, one end of a cooling pipe is wound through the hub motor and connected to one end of the circulating cylinder in a communicating mode, the other end of the cooling pipe is wound through the fixing frames and connected to the other end of the circulating cylinder in a communicating mode, an impeller is arranged in the circulating cylinder, the impeller is coaxially fixed to the inner side of the rotating ring and drives the hub to rotate along with the hub motor, pulleys are attached to the ring frame to quickly rotate so as to drive the blades to quickly rotate to blow air, and meanwhile, the inner ring drives the impeller to synchronously and rapidly rotate so as to drive a cooling medium to circularly flow in the cooling pipe, so that heat generated on the hub motor is rapidly taken away.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of hub motor heat dissipation, and in particular to a protective cooling device for hub motors. Background technique [0002] With the rapid increase in the number of cars, it also brings about serious environmental pollution and energy shortage problems. For this reason, the traditional automobile industry is gradually targeting the emerging field of electric vehicles. As early as 1900, the front wheel equipment hub has been manufactured. In addition, in recent years, thanks to the rapid development of the logistics system, the AGV (Automated Guided Vehicle) car with the advantages of high degree of automation, stable work, unmanned driving and simple operation has been adopted Widely used in aerospace, transportation, national defense and military fields, and AGV cars usually use hub motors placed in the hub to directly drive the wheels to rotate and walk.

AI Technical Summary

Problems solved by technology

[0003] If the heat generated by the hub motor under different working conditions cannot be dissipated in time in the hub, it is prone to failures such as insufficient power provided by the hub motor, affecting the accuracy of transportation, damage to the braking system, and burning of the motor, and even damage to the transported items and working space. , and with the increase of vehicle speed, the heat generated by the motor also gradually increases. The main methods for heat dissipation of hub motors are natural cooling method and forced air cooling method. Natural cooling is based on its own structure and conducts heat through the thermal conductivity of the material, which is low in cost. But the heat dissipation capacity is poor; the forced air cooling heat dissipation capacity is relatively good, but it will inevitably bring a large amount of additional energy loss, and the corresponding noise is also relatively large
