发明名称 Tensioning device i.e. short-arm tightener, for traction mechanism drive e.g. belt drive, in internal combustion engine, has tightener carrier prestressed at base part by spring elements so that carrier sums spring forces of elements
摘要 <p>The device has a tightener carrier (6) rotatably supported on a centrally arranged bearing journal (2) of a fixed base part (1) over a sliding bearing (4) by a hub-shaped bearing part (5). The carrier is prestressed at the base part by two spring elements (11, 12) such that the carrier sums operative spring forces of the spring elements. The spring elements concentrically surround the bearing part, and are arranged concentric to each other and supported at the base part at one end and at the carrier at another end. The elements are formed by screw and/or spiral-shaped torsion springs.</p>
