Problems solved by technology

[0003] In order to solve the problem that the intelligent unmanned car in the background needs to change the wheels and shoes in different terrains, and to meet the needs of the intelligent unmanned cars on the market for a chassis that can perform wheel and shoes changes, the present invention provides a chassis that can change wheels and shoes
The difference from many existing technologies is that the present invention realizes the use of the same power system to operate two different running mechanisms, and does not need to use hub motors to solve the problem of power system incompatibility

Embodiment Construction

[0016] The present invention will be described in further detail below with reference to examples and accompanying drawings.

[0017] figure 1 As shown, the present invention is a chassis capable of changing the wheel and track, including a wheel hub deformation part, a power switching part, and a front rocker part.

[0018] figure 1 and Figure 4 As shown, the front rocker is mainly composed of a front rocker 8, a front track wheel 9, a front wheel support rod 10 and a front wheel 11. The front rocker 8 can swing up and down under the driving of the steering gear, and the front track wheel 9 is connected to the front rocker. The rod 8 is connected by a pin, the front wheel 11 is connected with the front wheel support rod 10 by a pin, and the front wheel support rod 10 is connected to the steering gear fixed on the front crawler wheel and can swing up and down.

[0019] Figure 8 As shown, it includes the deformable hub 2, the floating bar 4, the axle coupler 5, the main a...

Abstract

The invention discloses a wheel-track switching chassis which comprises a wheel-track power switching part, a wheel-track switching part and a front rocker part, and the wheel-track power switching part comprises an axle coupler, an oil pushing sliding block, a main axle, a main shaft gear, a front shaft gear, an ordinary gear train, a lead screw, a driving motor, a guide rail and a lead screw driver; the wheel-track switching part comprises a track, a convertible hub, a hub hydraulic rod, a floating strip, an axle coupler, a track wheel and a main axle; the front rocker part comprises a front rocker, a front crawler wheel, a front supporting rod and a front wheel, and the front rocker, the front crawler wheel, the front supporting rod and the front wheel form a mechanical arm capable of swinging up and down. Two different walking mechanisms are provided, the same power system is used, a hub motor and the like do not need to be used for solving the problem of incompatibility of the power system, and the chassis can be conveniently applied to a small exploration device.

Description

technical field [0001] The invention relates to a chassis structure, in particular to a wheel track changing chassis with a hydraulic rod adjusting the shape of a hub. Background technique [0002] As an important component of the smart car, the chassis is mainly responsible for providing reliable and stable power for the smart car, as well as providing corresponding auxiliary functions. This chassis is suitable for unmanned express vehicles, fire fighting trolleys and various small robots that climb stairs. This deformable chassis can meet the requirements of the unmanned car for climbing stairs and fast driving at the same time, and provides a reliable chassis for the intelligent unmanned car. The current application number is CN201310047258.2, and the title is "A Four-Link Wheel Track Transformation Mechanism for a Wheel Track Changed Structure Mobile Robot", which provides a structure that can perform wheel track transformation. In this patent, the contour shape is cha...
