Transmission system of intelligent inspection robot

Abstract

The utility model provides an intelligent inspection robot transmission system which comprises a steering engine assembly, a shock absorber assembly and a driving assembly, and a hub rotating support shaped like a Chinese character'wang 'is arranged between the driving assembly and the steering engine assembly and located on the front end side of the driving assembly. The shock absorber assembly is connected with the rear upper end of the hub rotating support shaped like the Chinese character'wang 'and the rear end side of the traveling assembly, a joint motor is adopted for a horizontal driving part of the steering engine assembly, and a servo motor is adopted for a front-back driving part of the traveling assembly. By adopting the mode that the joint motor controls the transmission system to steer and the spline is matched with and fixes the joint motor, steering integrated control is added, the transmission accuracy is improved, the risk that the joint motor is exposed and is prone to damage is reduced, the requirement for the space size of a chassis is reduced, the structure is more compact, and rapid mounting and dismounting are convenient; the steering engine assembly and the walking assembly are independently designed, so that the whole transmission system meets the national II-class anti-explosion requirement and the IP66 / 68 sealing grade requirement.
