Design Features Analysis of the Multifunctional Transport Platform with Cross-Country Capacity

Abstract

The purpose of the article is to conduct a comparative analysis of the technical characteristics and design
features of transport platforms with cross-country capacity.

The novelty of the proposed design is the method of fastening the undercarriages to the platform body. The coupling pin of the undercarriage is installed in the bearing unit of the body. These two elements ensure the mobility of the undercarriages relative to the body in the vertical plane. Thus, two wheels of the undercarriages are constantly in contact with the ground. The undercarriage contains helium lead-acid traction batteries, a brushless DC electric motor, a chain transmission, and all wheels are driving.

The range of motion of the undercarriage relative to the body is limited by two springs. The ends of the springs are fixed to the body, the central part of the springs is fixed to the undercarriage. The damping of the undercarriage oscillations relative to the platform in the horizontal plane is achieved by installing limiters. The undercarriage is constantly pressed against the limiters and slides along them during vertical movement relative to the body.

The developed platform has high maintainability, due to the use of a minimum number of purchased components, as well as the possibility of modifications due to the different design of the body, applicable to the purpose of the platform.
