Description

Technical Field

[0001] The present invention belongs to the technical field of armored vehicle propulsion systems, and in particular relates to a modular power unit flexible support device. Background Art

[0002] The propulsion system, the core system for ensuring the mobility of armored vehicles, comprises the powertrain, transmission, auxiliary systems, and battery system. To meet the overall design requirements for high power density, high mobility, and environmental adaptability within the vehicle powertrain's spatial constraints, modular powertrains with multiple tonnages, serialization, universality, and various configurations (including transverse and longitudinal powertrain placement, and standalone powertrains) within the propulsion system have become a research hotspot. However, during assembly and commissioning, dedicated support brackets are required for each vehicle architecture. These brackets, designed for powertrains of varying tonnages and modular configurations, are not universal and are fixed to the powertrain at fixed points, preventing flexible adjustment. Due to operational space constraints, the assembly process must be performed sequentially, from power unit to transmission unit (or vice versa), preventing parallel assembly steps. After assembly, the test bench must be refitted with test fixtures, hindering assembly and commissioning efficiency and failing to meet the requirements for the efficient development and use of modular powertrains with multiple tonnages, serialization, universality, and various configurations.

[0003] Therefore, those skilled in the art need to design a modular flexible support device that can not only meet the requirements of modular power unit assembly with multiple tonnage, universality, serialization, and various forms (horizontal power transmission device, longitudinal power transmission device, etc.), but also meet the requirements of parallel multi-process of power unit and transmission unit and test bench testing, so as to solve the above-mentioned problems existing in the prior art.

It supports the longitudinal layout of the power transmission device, with the power unit and transmission unit axes arranged in a normal orientation. It is adjustable along the length of the transmission device, the spacing between the power unit and transmission device, and the length and width of the power unit. If necessary, the height of the power unit and transmission unit axes can be adjusted by changing the height of the transmission unit suspension support. If necessary, the position of the power unit and transmission unit can be adjusted by adding a transmission unit connecting flange. This provides flexible support for the power transmission device at the module port. Locking pins, locking screws, and locking holes enable control of the original point position, allowing for rapid reset and tightening. The height of the transmission unit output axis is aligned with the height of the test bench dynamometer axis, enabling integrated assembly and adjustment. After final assembly, the unit can be moved to the dynamometer bench and the power unit and transmission unit legs can be locked. This reduces tooling replacement time, simplifies final assembly and commissioning, and achieves efficient installation of the power transmission device.

10. The modular power plant flexible support device according to claim 8, characterized in that: The double-group mode is a grouping mode of the power unit bracket or the transmission unit bracket itself; the power unit bracket is fastened together with bolts and nuts through the power unit longitudinal connection flange; it is used to support high-load multi-point complex devices; and has flexible adjustment and locking functions at each point.
