A magnetically driven track wheel that can switch between the wheel state and the track state

Abstract

The invention discloses a magnetically driven crawler wheel which can switch between a wheel type state and a crawler type state, comprising a fixed-length crawler belt and a driving device for driving the fixed-length crawler belt to rotate; the driving device includes: a cage, a drive brake assembly, and a cage Including the inner bracket and the outer bracket device, the outer bracket device is symmetrically fixed on the left and right sides of the inner bracket; the outer bracket device includes the outer bracket and the bracket connecting sleeve, there are several outer brackets, and several outer brackets are evenly distributed on the bracket connection On the outer circumference of the sleeve; the outer bracket is connected with an actuator for changing the fixed-length track; the driving brake assembly includes a magnetic rotor and a driving stator that drives the magnetic rotor to rotate. The driving stator is fixed on the inner bracket, and the magnetic rotor is connected in rotation. Between the actuators on the left and right sides of the inner bracket; the magnetic rotor meshes with the fixed-length crawler belt to drive the fixed-length crawler belt to rotate; the invention can perform mutual conversion between the wheel type and the crawler type according to different road conditions and terrains, and improves the practicality. sex.

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
