Southward pointing cart with composite fixed-axis differential mechanism

Abstract

The invention relates to a southward pointing cart with composite fixed-axis differential mechanism. The southward pointing cart comprises a gear assembly, a clutch assembly and a connecting push rod assembly, wherein the clutch assembly is located above the gear assembly and connected with the gear assembly through a center stand column, the connecting push rod assembly is located at the two ends of the clutch assembly, a pointing rod is fixedly connected to the upper portion of the clutch assembly. A directional beacon is mounted on the pointing rod. The gear assembly is fixedly connected with wheels through a gear shaft, a shell is arranged between the gears, the gear shaft penetrates through a side plate of the shell and is rotationally connected with the side plate through a bearing, and the pointing rod penetrates through a top plate of the shell and is rotationally connected with the top plate through a bearing. The southward pointing cart with the composite fixed-axis differential mechanism can solve the problem that an existing southward pointing cart is inaccurate in orientation.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a compass car with a composite fixed-axis differential mechanism. Background technique [0002] Over the years, people have obtained a lot of results in the research on the transmission mechanism of the guide car. These researches have greatly activated the research field of mechanics, resulting in the emergence of many new mechanisms with different functions, and promoted the development of mechanical research. However, there are also deficiencies in previous research and practice. For example, most of them only use gear transmission or adopt quite complex structural designs, and some use electronic control methods such as single-chip microcomputers, but none of them has a relatively simple structure. , the design scheme of the transmission mechanism with relatively complete functions is put forward, which needs to be further developed. Starting from the combina...
