Embodiment Construction

[0058] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0059] see Figure 1 to Figure 7, the present invention provides a new type of wheel-track compound variable structure wheel, which is used in the mobile chassis that needs to change the walking mode at any time under the complex terrain environment, and can realize the wheel-track conversion according to the needs, specifically including the drive shaft 1, the telescopic deformation mechanism 2 , gear transmission mechanism 3 and rubber track 4, wherein:

[0060] Both the telescopic deformation mechanism 2 and the gear transmission mechanism 3 are installed on the drive shaft 1;

[0061] The drive shaft 1 is used to transmit the power input by an external vehicle engine (such as an off-road vehicle engine) to drive the rotation of the enti...

Abstract

The invention discloses a novel wheel-track composite variable structure wheel which comprises a driving shaft (1), a telescopic deformation mechanism (2), a gear transmission mechanism (3) and a rubber track (4). The telescopic deformation mechanism and the gear transmission mechanism are installed on the driving shaft; the driving shaft is used for transmitting power input by an external vehicleengine and driving the whole wheel-track composite variable structure wheel body to rotate; the gear transmission mechanism comprises two planet-like gear sets which are installed on a front side anda rear side of the wheel-track composite variable structure wheel body respectively; and the rubber track is tightly hooped on the outer side of the wheel-track composite variable structure wheel body and is used for driving after deformation switching between a wheel type state and a track type state. In the invention, mutual conversion of wheel shapes in circles and approximate triangles duringadvancing can be realized so that a mobile chassis has characteristics of quickness, flexibility, high environmental adaptability, high maneuverability and the like when operating in unstructured complex environments such as unpaved road surfaces, disaster relief and the like.

Description

technical field [0001] The invention relates to the technical field of mobile chassis, in particular to a novel wheel-track compound variable-structure wheel, which can realize wheel-track conversion as required, and is used in a mobile chassis that needs to change the walking mode at any time in a complex terrain environment. Background technique [0002] At present, there are two types of mature wheel-track mobile chassis: wheel-track combined type and wheel-track replaceable type. Among them, the wheel-track combined mobile chassis has two systems of wheel type and track type, which can take into account both wheel type and track type. However, the structure is bloated, bulky, and not compact enough; the replaceable wheel-track mobile chassis adopts replaceable track wheels, which can be off-road and walk on all terrains, with small vibration and low noise. The disadvantage is that the replacement of the chassis is more troublesome and requires It takes a long time, and t...
