Excavator and chassis thereof
The invention discloses an excavator and a chassis thereof in the technical field of excavator bottom plates, and aims to solve the problem of huge rotation resistance of an upper vehicle part when the excavator runs on a slope section in the prior art. Comprising; when the slope direction of the road surface is approximately overlapped with the uphill and downhill direction, the pitching oil cylinder telescopically drives the slewing bearing mounting table and the base to pitch around the middle frame, the included angle between the axis of the slewing bearing shaft and the gravity direction of the loading part is reduced on one degree of freedom, and then the axis of the slewing bearing shaft is adjusted to be approximately overlapped with the gravity direction of the loading part; when the component direction of a part of the gradient of the road surface is approximately overlapped with the uphill and downhill directions and the component direction of the other part points to the left side and the right side, the at least two pitching oil cylinders unequally stretch out and draw back to drive the slewing bearing mounting table to tilt towards the left side and the right side around the base, and the included angle between the axis of the slewing bearing shaft and the gravity direction of the getting-on part is reduced on two degrees of freedom; and then the axis of the slewing bearing shaft is adjusted to be approximately coincident with the gravity direction of the loading part.
本发明公开了挖掘机底板技术领域的挖掘机及其底盘，旨在解决现有技术中行驶在坡度段时上车部分回转阻力巨大的问题。其包括;当路面坡度方向与上下坡方向接近重合时，俯仰油缸伸缩驱动回转支承安装台与底座绕中间架俯仰，在一个自由度上减小回转支承轴的轴心线与上车部分的重力方向夹角，进而调整回转支承轴的轴心线与上车部分的重力方向接近重合；当路面坡度部分分量方向与上下坡方向接近重合，还有部分分量方向指向左右两侧时，至少两个俯仰油缸不平等伸缩驱动回转支承安装台绕底座朝左右两侧倾转，在两个自由度上减小回转支承轴的轴心线与上车部分的重力方向夹角，进而调整回转支承轴的轴心线与上车部分的重力方向接近重合。
