Position-adjustable driving wheel assembly

Abstract

The invention relates to the technical field of vehicles, in particular to a position-adjustable driving wheel assembly which comprises a driving wheel assembly body, a driving wheel adjusting mechanism and a driving wheel power transmission device. The assembly is used for the crawler walking system, the position of the driving wheel assembly body can be adjusted, and the driving wheel assembly body can drive a crawler belt while tensioning the crawler belt.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a position-adjustable driving wheel assembly. Background technique [0002] The drive and tensioning functions in existing crawler systems are implemented using different components or devices: [0003] First, the driving device is fixed relative to its supporting parts, that is, the position of the driving wheel cannot be adjusted, and it only has the function of driving or supporting, and does not have the function of tensioning the crawler. The reconfigurable variant wheel, application number 201922303041.9, in this patent is in contact with the inner side of the track through three auxiliary load-bearing wheels, which mainly play the role of supporting the load-bearing of the auxiliary cage and have no tensioning function; another example is disclosed in the Chinese patent. An all-terrain adaptive wheel track and its application, application number: 201910034000.6, the driv...

AI Technical Summary

Problems solved by technology

[0003] One is that the driving device is fixed relative to its supporting parts, that is, the position of the driving wheel cannot be adjusted, and it only has the function of driving or supporting, and does not have the function of tensioning the track. For example, a Chinese patent discloses a wheel-track switching The reconfigurable variant wheel, application number 201922303041.9, in this patent, three auxiliary load-bearing wheels are in contact with the inner side of the track, which mainly play the role of assisting the load bearing of the cage, and do not have the function of tensioning; another example is the Chinese patent disclosure An all-terrain adaptive wheel track and its application, application number: 201910034000.6, the driving wheel in this patent plays the role of driving the track, and also does not have the function of tensioning the track

Another example is a wheel-shoe two-mode deformed wheel, application number: 202110380082.7, the second driving gear in this patent is also fixed on the support frame, mainly plays the role of driving the track, and cannot be adjusted, and the track cannot be tensioned

[0004] The second is that the tensioning device has the function of tensioning the track, but does not have the function of driving the track, such as a wheel-track compound deformation wheel, application number: 201611113617.X, the main wheel of the expansion arm in this patent also plays the role of tensioning the track role, it does not have the function of driving the track

Another example is that a Chinese patent discloses a wheel-track composite deformation chassis, application number: 201910365957.9. The rollers in this patent also play the role of tensioning the track, and the roller does not have the function of driving the track.

The Chinese patent also discloses a crawler tensioning method, a crawler tensioning system and engineering machinery, application number 201310015517.3. This patent controls the extension of the tensioning oil cylinder by detecting the tension of the crawler belt to tension the crawler belt. Although this patent can Tensions the track, but does not have the function of driving the track

[0005] Neither the driving device nor the tensioning device in the above prior art can have the functions of tensioning the crawler belt and driving the crawler belt at the same time
