The springing device includes pivot points (10, 11) on the bearers (1), to which crossing struts (2, 3) are attached. At about half their length, the struts have elongated holes (2a, 3a) covered by shells (4, 5) which can move along them. A pivot bolt (8) passes through the shells and holes. the struts contain compression springs (6, 7). |
