Wheel mechanism for testing trolley chassis of remotely piloted vehicle

Abstract

The invention discloses a wheel mechanism for testing a trolley chassis of a remotely piloted vehicle. The wheel mechanism is provided with a wheel support, a first cross rod and a second cross rod, wherein the first cross rod and the second cross rod are arranged between the two sides of the wheel support and parallel to each other. The wheel mechanism is provided with at least two driving wheel units and at least one universal wheel unit. Each driving wheel unit is provided with a driving wheel and a driving motor assembly. One side of each driving motor assembly is connected with the wheel support through a first rotating assembly, and the other side of each driving motor assembly is connected with the first cross rod through a first spring assembly. Each universal wheel unit is provided with a universal wheel, a second rotating assembly and a second spring assembly. When the wheel mechanism suffers from huge flashy loads, four wheels can automatically shrink inwards, high loads are borne by a chassis body mechanism, losses of vulnerable parts of the wheel mechanism are reduced accordingly, and the trolley chassis of the remotely piloted vehicle is tested more economically in a more environment-friendly mode.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle testing, in particular to a wheel mechanism of an unmanned vehicle testing trolley chassis. Background technique [0002] In the process of testing the safety of the driverless car, the test car often causes a huge instantaneous load on the chassis of the test car due to the bouncing and impact of the wheels of the driverless car, which also brings a huge momentary load to the wheel mechanism of the car chassis. Because the wheel mechanism of the existing test trolley chassis is a rigid wheel mechanism, when a huge instantaneous load acts on the wheel mechanism, it will often cause damage to the wheel, aggravating the wear and tear on the wheel, thereby reducing the service life of the test trolley chassis. And it is not economical and environmentally friendly, causing a waste of social resources. Contents of the invention [0003] The present invention aims at defects such as the rigi...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at defects such as the rigidity of the wheel mechanism of the unmanned vehicle test trolley chassis in the prior art, the easily damaged wheels, the reduction of the service life of the test trolley chassis, and the waste of social resources. After a huge instantaneous load, the four wheels can be automatically retracted, so that the high load can be borne by the main body of the chassis, thereby reducing the loss of the vulnerable parts of the wheel mechanism, and the wheel mechanism of the chassis of the unmanned vehicle test trolley is more economical and environmentally friendly.
