Magnetically driven crawler wheel capable of switching wheel state and crawler state

Abstract

The invention discloses a magnetically driven crawler wheel capable of switching a wheel state and a crawler state. The wheel includes a fixed-length crawler and a driving device driving the fixed-length crawler to rotate. The driving device includes a cage and driving brake assemblies. Each cage includes inner brackets and outer fixing frame devices. The outer fixing frame devices are symmetrically fixed on the left and right sides of the inner brackets. Each outer fixing frame device includes outer brackets and a bracket connecting sleeve. The outer brackets are several. The several outer brackets are evenly distributed on the outer circumference of the corresponding bracket connecting sleeves. An actuator for switching a state of the fixed-length crawler is connected to each outer bracket. Each driving brake assembly includes a magnetic rotor and a driving stator driving the corresponding magnetic rotor to rotate. The driving stators are fixed to the inner brackets. Each magnetic rotor is rotatably connected between the actuators on the left and right sides of the corresponding inner bracket. The magnetic rotors are engaged with the fixed-length crawler to drive the fixed-lengthcrawler to rotate. The magnetically driven crawler wheel capable of switching the wheel state and the crawler state can switch the wheel state and the crawler state according to different road conditions, which improves the practicability.

Description

technical field [0001] The invention relates to the technical field of vehicle walking, in particular to a magnetically driven crawler wheel that can switch between a wheel-type state and a crawler-type state. Background technique [0002] The problems to be solved by all-terrain vehicles are: adaptability to complex environments, good obstacle-surmounting ability and certain speed. At present, common all-terrain vehicle traveling mechanisms are divided into leg type, wheel type, crawler type, compound type and the like. Although the leg-type driving mechanism has good adaptability and strong obstacle-crossing ability, it also has the disadvantages of too complicated structure, low moving efficiency, and difficult control; the composite driving mechanism has multiple sets of drive systems, and the structure and control are relatively complicated. But it is suitable for some special circumstances. Therefore, these two forms are less used. The wheel and the crawler have bec...

AI Technical Summary

Problems solved by technology

The main disadvantages of the wheeled driving mechanism are: because the wheels are in point or line contact with the ground, the grip performance of the wheels is poor, and they do not have the ability to prevent subsidence; because the ability of the round wheels to cross the vertical wall is proportional to the size of the wheel diameter , so its off-road capability is limited by the height limit of the wheel body

Although the existing technology can expand the diameter of the wheel to about 2.5 meters, its huge wheel body takes up too much car body space. The bigger problem is that a wheel with a diameter of 2.5 meters occupies a lot of space. The effective space of the car body is huge, and the required steering space greatly reduces the effective space of the car body. With the increase of the wheel diameter, the weight of the wheel itself will also increase. The above shortcomings directly limit the The practicality of large diameter wheels

The main disadvantages of crawler type: one is that the fuel consumption of the whole vehicle is large

[0004] The wheel-track combined vehicle invented at present overcomes the shortcomings of ordinary tracked vehicles and tire vehicles, such as high energy consumption and weak obstacle-crossing ability, and comprehensively improves the driving performance of the vehicle. However, its drive system mostly uses the drive system of traditional fuel vehicles. The energy loss of the link, the power transmission and conversion efficiency of the vehicle are seriously affected
