自动平地机环形驱动组件
摘要：
本发明公开一种用于自动平地机的环形驱动组件。环形驱动组件包括：能够围绕转动轴线转动的环形部件、用于能够转动地驱动环形部件的第一液压缸和第二液压缸、以及第一和第二连接机构。第一液压缸具有连接到第一连接机构的第一端，并且第二液压缸具有连接到第二连接机构的第二端。第一连接机构和第二连接机构能够控制地在夹紧位置和非夹紧位置之间移动。在第一连接机构处于夹紧位置中时，第一液压缸能够转动地驱动环形部件，并且在第二连接机构处于夹紧位置中时，第二液压缸能够转动地驱动环形部件。
摘要（英）：

The present disclosure provides a circle drive assembly for a motor grader. The circle drive assembly includes a circle member being rotatable about a rotation axis, a first hydraulic cylinder and a second hydraulic cylinder for rotatably driving the circle member, and a first and second coupling mechanisms. The first hydraulic cylinder has a first end coupled to the first coupling mechanism and the second hydraulic has a second end coupled to the second coupling mechanism. The first coupling mechanism and second coupling mechanism can be controllably moved between a clamped position and an unclamped position. The first hydraulic cylinder rotatably drives the circle member when the first coupling mechanism is in the clamped position and the second hydraulic cylinder rotatably drives the circle member when the second coupling mechanism is in the clamped position.
