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...

Examples

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...
