摘要
军用越野车对动力装置要求日益增高，采用液压马达驱动可以有效的提高车辆的动力性和通过性。将马达、减速器和制动器集成在轮毂中，设计出动力性强于轮毂电机的集成式液动轮，完全改变了传统车辆的传动结构，增加了车内空间。液动轮的使用可以较好的提高整车的性能，增强作战能力。本文阐述了液压驱动的基本原理和优点，液动轮的设计流程，选定了液压马达的类型和布置形式。进行了整体的方案设计、配齿计算和关键部件的校核并进行了相关零件的结构设计。经过绘制二维图纸对比不同方案的优缺点后，确定了整体方案，并绘制三维图进行装配流程的设计以及干涉排查。最终基于北京理工大学“薪火摇臂无人平台”完成了集成式液动轮一体化的设计。

Abstract
As military off-road vehicles place increasingly greater demands on vehicle power plants, employing hydraulic motors can effectively improve vehicle dynamic performance and trafficability. This thesis integrates motor, speed reducer and brake into the wheel hub, designs an integrated hydraulic power wheel with better dynamic performance than in-wheel motor, differing completely from traditional vehicles in terms of transmission device, and saving room for the vehicle. Hydraulic wheel can improve vehicle performance and strengthen its abilities in the battlefield. This thesis elaborates the basic principles and advantages of a hydraulic motor, introduces the designing process of a hydraulic wheel, and determines the type of hydraulic motor and its detailed design. The thesis makes an overall design, calculates gear tooth parameter, checks key accessories and forms physical design of certain accessories. After drafting plans and comparing the advantages and disadvantages between two designs, an overall design is decided and a graphic model is established, with assembly process well designed and interference ruled out. Finally, based on the “Xinhuo” rockers unmanned vehicle, the design of an integrated hydraulic power wheel is completed.
