Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of armored vehicle propulsion system, and particularly relates to a multifunctional high-precision power device flexible support and calibration device. BACKGROUND

[0002] As the core system to meet the mobility of armored vehicles, the propulsion system includes a power system, a transmission system, an auxiliary system, and a power battery system. In order to meet the overall design requirements of high power density, high mobility, and high environmental adaptability of vehicle power transmission device in space, the modularized power device of multiple tonnage, serialization, generalization, and multiple forms (power transmission device transverse, power transmission device vertical, and power transmission device used alone) has become a research hotspot. However, during the general assembly and adjustment process, first of all, all general assembly products need to be weighed and data recorded before they can be installed on the tool support. Secondly, the tool support needs to be designed for each vehicle architecture to provide support. The tool support for power transmission devices of multiple tonnage and multiple modular configurations cannot be used universally, and it is connected to the power device at fixed points and cannot be flexibly adjusted. Thirdly, the tool support only serves as a support. Due to space and power device interference, the traditional steel ruler and tape measure cannot effectively measure the distance between the points, and the measurement accuracy cannot be guaranteed, which cannot support the distance calibration between the power device support positions. Moreover, due to the operation space and process interference, the operation process can only be installed in the order of power unit-transmission unit (or vice versa), and the general assembly process cannot be parallel. After the general assembly is completed, the test tool needs to be replaced on the test bench. In summary, due to the above reasons, the existing technology and tool support result in low efficiency of power device assembly and adjustment, which cannot meet the high-efficiency research and development requirements of power devices of multiple tonnage, serialization, generalization, and multiple forms of modular power devices.
