摘要

振动压路机是利用其自身的重力和振动压实各种建筑和筑路材料。在公路建设中，振动压路机最适宜压实各种非粘性土壤、碎石、碎石混合料以及各种沥青混凝土而被广泛应用。目前国产振动压路机以中小吨位和机械传动方式为主，而性能优良的全液压重型振动压路机主要依赖于进口。之所以出现处于这种状况是由于全液压压路机液压液压系统结构比较复杂并且各类液压元件加工复杂，为彻底改变这种现状本文对现有压路机液压系统进行调研，研制出结构优良的全液压压路机液压系统。

本文在理论分析和计算的基础上，完成了YZJ13型振动压路机液压系统的设计，在方案、结构和设计方法上进行了创新：采用全液压的传动方案，通过3个相互独立的液压回路实现行驶、振动和转向三大基本功能，与机械传动相比在压实效果、爬坡能力、质量分配、操作控制和整体布局方面具备更大优势。转向结构采用铰接式车架折腰转向的方案，转弯半径小、机动性好、前后轮迹重叠、重心低、驾驶员视野开阔。同时本文对分动箱的机构进行了详细的设计计算，为缩小分动箱的体积本次采用齿面硬度达60HRC的齿轮和双列滚柱轴承的结构。

Abstract

Vibratory roller is the use of its own gravity and vibration compaction of various building and road construction materials. In the process of highway construction, vibratory roller is the most suitable for compaction of various kinds of non cohesive soil, crushed stone, crushed stone mixture and asphalt concrete. At present, the domestic vibratory roller is mainly based on the medium and small tonnage and mechanical transmission mode, and the full hydraulic vibratory roller with good performance mainly depends on import. The reason in this situation is due to hydraulic roller hydraulic system of complex structure and various hydraulic components processing complex, to completely change this situation in the research of the existing roller hydraulic system, developed the fine structure of the full hydraulic roller hydraulic system.

In this paper, on the basis of theoretical analysis and calculation, completed the design of YZJ13 type hydraulic system of vibratory roller, the innovation in the scheme, structure and design method: using hydraulic transmission scheme, realize the vibration and turned to the three basic functions of the 3 independent hydraulic circuits, compared with mechanical the transmission has more advantages in the compaction effect, climbing ability, quality distribution, operation control and overall layout. Steering articulated frame structure using articulated steering scheme, small turning radius, good maneuverability, and the wheel track overlap, low center of gravity, the driver vision. At the same time, the mechanism of the transfer case were calculated with the structure design, in order to reduce the volume of the transfer gear tooth surface hardness of 60HRC gear and double row roller bearing.
